California is one of at least nine States that authorize the use of marijuana for medicinal purposes.1 The question presented in this case is whether the power vested in Congress by
I
California has been a pioneer in the regulation of marijuana. In 1913, California was one of the first States to prohibit the sale and possession of marijuana,2 and at the end of the century, California became the first State to authorize limited use of the drug for medicinal purposes. In 1996, California voters passed Proposition 215, now codified as the Compassionate Use Act of 1996.3 The proposition was de-
Respondents Angel Raich and Diane Monson are California residents who suffer from a variety of serious medical conditions and have sought to avail themselves of medical marijuana pursuant to the terms of the Compassionate Use
Respondent Monson cultivates her own marijuana, and ingests the drug in a variety of ways including smoking and using a vaporizer. Respondent Raich, by contrast, is unable to cultivate her own, and thus relies on two caregivers, litigating as “John Does,” to provide her with locally grown marijuana at no charge. These caregivers also process the cannabis into hashish or keif, and Raich herself processes some of the marijuana into oils, balms, and foods for consumption.
On August 15, 2002, county deputy sheriffs and agents from the federal Drug Enforcement Administration (DEA) came to Monson‘s home. After a thorough investigation, the county officials concluded that her use of marijuana was entirely lawful as a matter of California law. Nevertheless, after a 3-hour standoff, the federal agents seized and destroyed all six of her cannabis plants.
Respondents thereafter brought this action against the Attorney General of the United States and the head of the DEA seeking injunctive and declaratory relief prohibiting the enforcement of the federal Controlled Substances Act (CSA), 84 Stat. 1242,
The District Court denied respondents’ motion for a preliminary injunction. Raich v. Ashcroft, 248 F. Supp. 2d 918 (ND Cal. 2003). Although the court found that the federal enforcement interests “wane[d]” when compared to the harm that California residents would suffer if denied access to medically necessary marijuana, it concluded that respondents could not demonstrate a likelihood of success on the merits of their legal claims. Id., at 931.
A divided panel of the Court of Appeals for the Ninth Circuit reversed and ordered the District Court to enter a preliminary injunction.8 Raich v. Ashcroft, 352 F. 3d 1222 (2003). The court found that respondents had “demonstrated a strong likelihood of success on their claim that, as applied to them, the CSA is an unconstitutional exercise of Congress’ Commerce Clause authority.” Id., at 1227. The Court of Appeals distinguished prior Circuit cases upholding the CSA in the face of Commerce Clause challenges by focusing on what it deemed to be the “separate and distinct class of activities” at issue in this case: “the intrastate, noncommercial cultivation and possession of cannabis for personal medical purposes as recommended by a patient‘s physician pursuant to valid California state law.” Id., at 1228. The
The majority placed heavy reliance on our decisions in United States v. Lopez, 514 U. S. 549 (1995), and United States v. Morrison, 529 U. S. 598 (2000), as interpreted by recent Circuit precedent, to hold that this separate class of purely local activities was beyond the reach of federal power. In contrast, the dissenting judge concluded that the CSA, as applied to respondents, was clearly valid under Lopez and Morrison; moreover, he thought it “simply impossible to distinguish the relevant conduct surrounding the cultivation and use of the marijuana crop at issue in this case from the cultivation and use of the wheat crop that affected interstate commerce in Wickard v. Filburn.” 352 F. 3d, at 1235 (opinion of Beam, J.).
The obvious importance of the case prompted our grant of certiorari. 542 U. S. 936 (2004). The case is made difficult by respondents’ strong arguments that they will suffer irreparable harm because, despite a congressional finding to the contrary, marijuana does have valid therapeutic purposes. The question before us, however, is not whether it is wise to enforce the statute in these circumstances; rather, it is whether Congress’ power to regulate interstate markets for medicinal substances encompasses the portions of those markets that are supplied with drugs produced and consumed locally. Well-settled law controls our answer. The CSA is a valid exercise of federal power, even as applied to the troubling facts of this case. We accordingly vacate the judgment of the Court of Appeals.
Shortly after taking office in 1969, President Nixon declared a national “war on drugs.”9 As the first campaign of that war, Congress set out to enact legislation that would consolidate various drug laws on the books into a comprehensive statute, provide meaningful regulation over legitimate sources of drugs to prevent diversion into illegal channels, and strengthen law enforcement tools against the traffic in illicit drugs.10 That effort culminated in the passage of the Comprehensive Drug Abuse Prevention and Control Act of 1970, 84 Stat. 1236.
This was not, however, Congress’ first attempt to regulate the national market in drugs. Rather, as early as 1906 Congress enacted federal legislation imposing labeling regulations on medications and prohibiting the manufacture or shipment of any adulterated or misbranded drug traveling in interstate commerce.11 Aside from these labeling restrictions, most domestic drug regulations prior to 1970 generally came in the guise of revenue laws, with the Department of the Treasury serving as the Federal Government‘s primary enforcer.12 For example, the primary drug control law, before being repealed by the passage of the CSA, was the Harrison Narcotics Act of 1914, 38 Stat. 785 (repealed 1970). The Harrison Act sought to exert control over the possession and sale of narcotics, specifically cocaine and opiates, by requiring producers, distributors, and purchasers to register with the Federal Government, by assessing taxes against
Marijuana itself was not significantly regulated by the Federal Government until 1937 when accounts of marijuana‘s addictive qualities and physiological effects, paired with dissatisfaction with enforcement efforts at state and local levels, prompted Congress to pass the Marihuana Tax Act, 50 Stat. 551 (repealed 1970).14 Like the Harrison Act, the Marihuana Tax Act did not outlaw the possession or sale of marijuana outright. Rather, it imposed registration and reporting requirements for all individuals importing, produсing, selling, or dealing in marijuana, and required the payment of annual taxes in addition to transfer taxes whenever the drug changed hands.15 Moreover, doctors wishing to prescribe marijuana for medical purposes were required to comply with rather burdensome administrative requirements.16 Noncompliance exposed traffickers to severe federal penalties, whereas compliance would often subject them to prosecution under state law.17 Thus, while the Marihuana Tax Act did not declare the drug illegal per se, the onerous administrative requirements, the prohibitively expensive taxes, and the risks attendant on compliance practically curtailed the marijuana trade.
Then in 1970, after declaration of the national “war on drugs,” federal drug policy underwent a significant transformation. A number of noteworthy events precipitated
Title II of that Act, the CSA, repealed most of the earlier antidrug laws in favor of a comprehensive regime to combat the international and interstate traffic in illicit drugs. The main objectives of the CSA were to conquer drug abuse and to control the legitimate and illegitimate traffic in controlled substances.20 Congress was particularly concerned with the
To effectuate these goals, Congress devised a closed regulatory system making it unlawful to manufacture, distribute, dispense, or possess any controlled substance except in a manner authorized by the CSA.
“(2) The illegal importation, manufacture, distribution, and possession and improper use of controlled substances have a substantial and detrimental effect on the health and general welfare of the American people.
“(3) A major portion of the traffic in controlled substances flows through interstate and foreign commerce. Incidents of the traffic which are not an integral part of the interstate or foreign flow, such as manufacture, local distribution, and possession, nonetheless have a substantial and direct effect upon interstate commerce because—
“(A) after manufacture, many controlled substances are transported in interstate commerce,
“(B) controlled substances distributed locally usually have been transported in interstate commerce immediately before their distribution, and
“(C) controlled substances possessed commonly flow through interstate commerce immediately prior to such possession.
“(4) Local distribution and possession of controlled substances contribute to swelling the interstate traffic in such substances.
“(5) Controlled substances manufactured and distributed intrastate cannot be differentiated from controlled substances manufactured and distributed interstate. Thus, it is not feasible to distinguish, in terms of controls, between controlled substances manufactured and distributed interstate and controlled substances manufactured and distributed intrastate.
“(6) Federal control of the intrastate incidents of the traffic in controlled substances is essential to the effective control of the interstate incidents of such traffic.”
In enacting the CSA, Congress classified marijuana as a Schedule I drug.
The CSA provides for the periodic updating of schedules and delegates authority to the Attorney General, after consultation with the Secretary of Health and Human Services, to add, remove, or transfer substances to, from, or between
III
Respondents in this case do not dispute that passage of the CSA, as part of the Comprehensive Drug Abuse Prevention and Control Act, was well within Congress’ commerce power. Brief for Respondents 22, 38. Nor do they contend that any provision or section of the CSA amounts to an unconstitutional exercise of congressional authority. Rather, respondents’ challenge is actually quite limited; they argue that the CSA‘s categorical prohibition of the manufacture and possession of marijuana as applied to the intrastate manufacture and possession of marijuana for medical purposes pursuant to California law exceeds Congress’ authority under the Commerce Clause.
In assessing the validity of congressional regulation, none of our Commerce Clause cases can be viewed in isolation. As charted in considerable detail in United States v. Lopez, our understanding of the reach of the Commerce Clause, as well as Congress’ assertion of authority thereunder, has
Cases decided during that “new era,” which now spans more than a century, have identified three general categories of regulation in which Congress is authorized to engage under its commerce power. First, Congress can regulate the channels of interstate commerce. Perez v. United States, 402 U. S. 146, 150 (1971). Second, Congress has authority to regulate and protect the instrumentalities of interstate commerce, and persons or things in interstate
Our case law firmly establishes Congress’ power to regulate purely local activities that are part of an economic “class of activities” that have a substantial effect on interstate commerce. See, e. g., Perez, 402 U. S., at 151; Wickard v. Filburn, 317 U. S. 111, 128-129 (1942). As we stated in Wickard, “even if appellee‘s activity be local and though it may not be regarded as commerce, it may still, whatever its nature, be reached by Congress if it exerts a substantial economic effect on interstate commerce.” Id., at 125. We have never required Congress to legislate with scientific exactitude. When Congress decides that the “total incidence” of a practice poses a threat to a national market, it may regulate the entire class. See Perez, 402 U. S., at 154-155 (“[W]hen it is necessary in order to prevent an evil to make the law embrace more than the precise thing to be prevented it may do so” (quoting Westfall v. United States, 274 U. S. 256, 259 (1927))). In this vein, we have reiterated that when ““a general regulatory statute bears a substantial relation to commerce, the de minimis character of individual instances arising under that statute is of no consequence.“” E. g., Lopez, 514 U. S., at 558 (quoting Maryland v. Wirtz, 392 U. S. 183, 196, n. 27 (1968); emphasis deleted).
Our decision in Wickard, 317 U. S. 111, is of particular relevance. In Wickard, we upheld the application of regulations promulgated under the Agricultural Adjustment Act of 1938, 52 Stat. 31, which were designed to control the volume of wheat moving in interstate and foreign commerce in order to avoid surpluses and consequent abnormally low prices. The regulations established an allotment of 11.1 acres for Filburn‘s 1941 wheat crop, but he sowed 23 acres, intending to use the excess by consuming it on his own farm. Filburn
“The effect of the statute before us is to restrict the amount which may be produced for market and the extent as well to which one may forestall resort to the market by producing to meet his own needs. That appellee‘s own contribution to the demand for wheat may be trivial by itself is not enough to remove him from the scope of federal regulation where, as here, his contribution, taken together with that of many others similarly situated, is far from trivial.” Id., at 127-128.
Wickard thus establishes that Congress can regulate purely intrastate activity that is not itself “commercial,” in that it is not produced for sale, if it concludes that failure to regulate that class of activity would undercut the regulation of the interstate market in that commodity.
The similarities between this case and Wickard are striking. Like the farmer in Wickard, respondents are cultivating, for home consumption, a fungible commodity for which there is an established, albeit illegal, interstate market.28 Just as the Agricultural Adjustment Act was designed “to
More concretely, one concern prompting inclusion of wheat grown for home consumption in the 1938 Act was that rising market prices could draw such wheat into the interstate market, resulting in lower market prices. Wickard, 317 U. S., at 128. The parallel concern making it appropriate to include marijuana grown for home consumption in the CSA is the likelihood that the high demand in the interstate market will draw such marijuana into that market. While the diversion of homegrown wheat tended to frustrate the federal interest in stabilizing prices by regulating the volume of commercial transactions in the interstate market, the diversion of homegrown marijuana tends to frustrate the federal interest in eliminating commercial transactions in the interstate market in their entirety. In both cases, the regulation is squarely within Congress’ commerce power because production of the commodity meant for home consumption, be it wheat or marijuana, has a substantial effect on supply and demand in the national market for that commodity.29
The fact that Filburn‘s own impact on the market was “trivial by itself” was not a sufficient reason for removing him from the scope of federal regulation. Wickard, 317 U. S., at 127. That the Secretary of Agriculture elected to exempt even smaller farms from regulation does not speak to his power to regulate all those whose aggregated production was significant, nor did that fact play any role in the Court‘s analysis. Moreover, even though Filburn was indeed a commercial farmer, the activity he was engaged in—the cultivation of wheat for home consumption—was not treated by the Court as part of his commercial farming operation.30 And while it is true that the record in the Wickard case itself established the causal connection between the production for local use and the national market, we have before us findings by Congress to the same effect.
Findings in the introductory sections of the CSA explain why Congress deemed it appropriate to encompass local activities within the scope of the CSA. See n. 20, supra. The
lar commodity. Lopez, 514 U. S., at 571 (KENNEDY, J., concurring) (“In the Lottery Case, 188 U. S. 321 (1903), the Court rejected the argument that Congress lacked [the] power to prohibit the interstate movement of lottery tickets because it had power only to regulate, not to prohibit“); see also Wickard, 317 U. S., at 128 (“The stimulation of commerce is a use of the regulatory function quite as definitely as prohibitions or restrictions thereon“).
To support their contrary submission, respondents rely heavily on two of our more recent Commerce Clause cases. In their myopic focus, they overlook the larger context of modern-era Commerce Clause jurisprudence preserved by those cases. Moreover, even in the narrow prism of respondents’ creation, they read those cases far too broadly.
Those two cases, of course, are Lopez, 514 U. S. 549, and Morrison, 529 U. S. 598. As an initial matter, the statutory challenges at issue in those cases were markedly different from the challenge respondents pursue in the case at hand. Here, respondents ask us to excise individual applications of a concededly valid statutory scheme. In contrast, in both Lopez and Morrison, the parties asserted that a particular statute or provision fell outside Congress’ commerce power in its entirety. This distinction is pivotal for we have often reiterated that “[w]here the class of activities is regulated and that class is within the reach of federal power, the courts have no power ‘to excise, as trivial, individual instances’ of the class.” Perez, 402 U. S., at 154 (quoting Wirtz, 392 U. S., at 193 (emphasis deleted)); see also Hodel, 452 U. S., at 308.
At issue in Lopez, 514 U. S. 549, was the validity of the
“Section 922(q) is a criminal statute that by its terms has nothing to do with ‘commerce’ or any sort of economic enterprise, however broadly one might define those terms. Section 922(q) is not an essential part of a larger regulation of economic activity, in which the regulatory scheme could be undercut unless the intrastate activity were regulated. It cannot, therefore, be sustained under our cases upholding regulations of activities that arise out of or are connected with a commercial transaction, which viewed in the aggregate, substantially affects interstate commerce.” 514 U. S., at 561.
The statutory scheme that the Government is defending in this litigation is at the opposite end of the regulatory spectrum. As explained above, thе CSA, enacted in 1970 as part of the
While the statute provided for the periodic updating of the five schedules, Congress itself made the initial classifications. It identified 42 opiates, 22 opium derivatives, and 17 hallucinogenic substances as Schedule I drugs. 84 Stat. 1248. Marijuana was listed as the 10th item in the 3d subcategory. That classification, unlike the discrete prohibition established by the Gun-Free School Zones Act of 1990, was merely one of many “essential part[s] of a larger regulation of economic activity, in which the regulatory scheme could be undercut
Nor does this Court‘s holding in Morrison, 529 U. S. 598. The
Unlike those at issue in Lopez and Morrison, the activities regulated by the CSA are quintessentially economic. “Economics” refers to “the production, distribution, and consumption of commodities.” Webster‘s Third New International
The Court of Appeals was able to conclude otherwise only by isolating a “separate and distinct” class of activities that it held to be beyond the reach of federal power, defined as “the intrastate, noncommercial cultivation, possession and use of marijuana for personal medical purposes on the advice of a physician and in accordance with state law.” 352 F. 3d, at 1229. The court characterized this class as “different in kind from drug trafficking.” Id., at 1228. The differences between the members of a class so defined and the principal traffickers in Schedule I substances might be sufficient to justify a policy decision exempting the narrower class from the coverage of the CSA. The question, however, is whether Congress’ contrary policy judgment, i. e., its decision to include this narrower “class of activities” within the larger regulatory scheme, was constitutionally deficient. We have no difficulty concluding that Congress acted rationally in determining that none of the characteristics making up the purported class, whether viewed individually or in the aggregate, compelled an exemption from the CSA; rather, the subdivided class of activities defined by the Court
First, the fact that marijuana is used “for personal medical purposes on the advice of a physician” cannot itself serve as a distinguishing factor. Id., at 1229. The CSA designates marijuana as contraband for any purpose; in fact, by characterizing marijuana as a Schedule I drug, Congress expressly found that the drug has no acceptable medical uses. Moreover, the CSA is a comprehensive regulatory regime specifically designed to regulate which controlled substances can be utilized for medicinal purposes, and in what manner. Indeed, most of the substances classified in the CSA “have a useful and legitimate medical purpose.”
Nor can it serve as an “objective marke[r]” or “objective facto[r]” to arbitrarily narrow the relevant class as the dissenters suggest, post, at 47 (opinion of O‘CONNOR, J.); post, at 68 (opinion of THOMAS, J.). More fundamentally, if, as the principal dissent contends, the personal cultivation, possession, and use of marijuana for medicinal purposes is beyond the “‘outer limits’ of Congress’ Commerce Clause authority,” post, at 42 (opinion of O‘CONNOR, J.), it must also be true that such personal use of marijuana (or any other homegrown drug) for recreational purposes is also beyond those “outer limits,” whether or not a State elects to authorize or even regulate such use. JUSTICE THOMAS’ separate dissent suffers from the same sweeping implications. That is, the dissenters’ rationale logically extends to place any federal regulation (including quality, prescription, or quantity controls) of any locally cultivated and possessed controlled substance for any purpose beyond the “outer limits” of Congress’ Commerce Clause authority. One need not have a degree in economics to understand why a nationwide exemption for the vast quantity of marijuana (or other drugs) locally cultivated for personal use (which presumably would include use by friends, neighbors, and family members) may have a substantial impact on the interstate market for this extraordinarily popular substance. The congressional judgment that an exemption for such a significant segment of the total market would undermine the orderly enforcement of the entire regulatory scheme is entitled to a strong presumption of validity. Indeed, that judgment is not only rational, but “visible to the
Second, limiting the activity to marijuana possession and cultivation “in accordance with state law” cannot serve to place respondents’ activities beyond congressional reach. The Supremacy Clause unambiguously provides that if there is any conflict between federal and state law, federal law shall prevail. It is beyond peradventure that federal power over commerce is “‘superior to that of the States to provide for the welfare or necessities of their inhabitants,‘” however legitimate or dire those necessities may be. Wirtz, 392 U. S., at 196 (quoting Sanitary Dist. of Chicago v. United States, 266 U. S. 405, 426 (1925)). See also 392 U. S., at 195-196; Wickard, 317 U. S., at 124 (“[N]o form of state activity can constitutionally thwart the regulatory power granted by the commerce clause to Congress“). Just as stаte acquiescence to federal regulation cannot expand the bounds of the Commerce Clause, see, e. g., Morrison, 529 U. S., at 661-662 (BREYER, J., dissenting) (noting that 38 States requested federal intervention), so too state action cannot circumscribe Congress’ plenary commerce power. See United States v. Darby, 312 U. S. 100, 114 (1941) (“That power can neither be enlarged nor diminished by the exercise or non-exercise of state power“).38
Indeed, that the California exemptions will have a significant impact on both the supply and demand sides of the market for marijuana is not just “plausible” as the principal dissent concedes, post, at 56 (opinion of O‘CONNOR, J.), it is readily apparent. The exemption for physicians provides them with an economic incentive to grant their patients permission to use the drug. In contrast to most prescriptions for legal drugs, which limit the dosage and duration of the usage, under California law the doctor‘s permission to
The exemption for cultivation by patients and caregivers can only increase the supply of marijuana in the California market.41 The likelihood that all such production will
So, from the “separate and distinct” class of activities identified by the Court of Appeals (and adopted by the dissenters), we are left with “the intrastate, noncommercial cultivation, possession and use of marijuana.” 352 F. 3d, at 1229. Thus the case for the exemption comes down to the claim that a locally cultivated product that is used domestically
V
Respondents also raise a substantive due process claim and seek to avail themselves of the medical necessity defense. These theories of relief were set forth in their complaint but were not reached by the Court of Appeals. We therefore do not address the question whether judicial relief is available to respondents on these alternative bases. We do note, however, the presence of another avenue of relief. As the Solicitor General confirmed during oral argument, the statute authorizes procedures for the reclassification of Schedule I drugs. But perhaps even more important than these legal avenues is the democratic process, in which the voices of voters allied with these respondents may one day be heard in the halls of Congress. Under the present state of the law, however, the judgment of the Court of Appeals must be vacated. The case is remanded for further proceedings consistent with this opinion.
It is so ordered.
JUSTICE SCALIA, concurring in the judgment.
I agree with the Court‘s holding that the Controlled Substances Act (CSA) may validly be applied to respondents’ cultivation, distribution, and possession of marijuana for personal, medicinal use. I write separately because my understanding of the doctrinal foundation on which that holding rests is, if not inconsistent with that of the Court, at least more nuanced.
Since Perez v. United States, 402 U. S. 146 (1971), our cases have mechanically recited that the Commerce Clause permits congressional regulation of three categories: (1) the
It is misleading because, unlike the channels, instrumentalities, and agents of interstate commerce, activities that substantially affect interstate commerce are not themselves part of interstate commerce, and thus the power to regulate them cannot come from the Commerce Clause alone. Rather, as this Court has acknowledged since at least United States v. Coombs, 12 Pet. 72 (1838), Congress‘s regulatory authority over intrastate activities that are not themselves part of interstate commerce (including activities that have a substantial effect on interstate commerce) derives from the Necessary and Proper Clause. Id., at 78; Katzenbach v. McClung, 379 U. S. 294, 301-302 (1964); United States v. Wrightwood Dairy Co., 315 U. S. 110, 119 (1942); Shreveport Rate Cases, 234 U. S. 342, 353 (1914); United States v. E. C. Knight Co., 156 U. S. 1, 39-40 (1895) (Harlan, J., dissenting).1 And the category of “activities that substantially affect interstate commerce,” Lopez, supra, at 559, is incomplete because the authority to enact laws necessary and proper for the regulation of interstate commerce is not limited to laws
I
Our cases show that the regulation of intrastate activities may be necessary to and proper for the regulation of interstate commerce in two general circumstances. Most directly, the commerce power permits Congress not only to devise rules for the governance of commerce between States but also to facilitate interstate commerce by eliminating potential obstructions, and to restrict it by eliminating potential stimulants. See NLRB v. Jones & Laughlin Steel Corp., 301 U. S. 1, 36-37 (1937). That is why the Court has repeatedly sustained congressional legislation on the ground that the regulated activities had a substantial effect on interstate commerce. See, e. g., Hodel, supra, at 281 (surface coal mining); Katzenbach, supra, at 300 (discrimination by restaurants); Heart of Atlanta Motel, Inc. v. United States, 379 U. S. 241, 258 (1964) (discrimination by hotels); Mandeville Island Farms, Inc. v. American Crystal Sugar Co., 334 U. S. 219, 237 (1948) (intrastate price fixing); Board of Trade of Chicago v. Olsen, 262 U. S. 1, 40 (1923) (activities of a local grain exchange); Stafford v. Wallace, 258 U. S. 495, 517, 524-525 (1922) (intrastate transactions at stockyard). Lopez and Morrison recognized the expansive scope of Congress‘s authority in this regard: “[T]he pattern is clear. Where economic activity substantially affects interstate commerce, legislation regulating that activity will be sustained.” Lopez, supra, at 560; Morrison, supra, at 610 (same).
This principle is not without limitation. In Lopez and Morrison, the Court—conscious of the potential of the “substantially affects” test to “obliterate the distinction between what is national and what is local,” Lopez, supra, at 566-567
As we implicitly acknowledged in Lopez, however, Congress‘s authority to enact laws necessary and proper for the regulation of interstate commerce is not limited to laws directed against economic activities that have a substantial effect on interstate commerce. Though the conduct in Lopez was not economic, the Court nevertheless recognized that it could be regulated as “an essential part of a larger regulation of economic activity, in which the regulatory scheme could be undercut unless the intrastate activity were regulated.” 514 U. S., at 561. This statement referred to those cases permitting the regulation of intrastate activities “which in a substantial way interfere with or obstruct the exercise of the granted power.” Wrightwood Dairy Co., supra, at 119; see also United States v. Darby, 312 U. S. 100, 118-119 (1941); Shreveport Rate Cases, supra, at 353. As the Court put it in Wrightwood Dairy, where Congress has the authority to enact a regulation of interstate commerce, “it possesses every power needed to make that regulation effective.” 315 U. S., at 118-119.
In Darby, for instance, the Court explained that “Congress, having . . . adopted the policy of excluding from interstate commerce all goods produced for the commerce which do not conform to thе specified labor standards,” 312 U. S., at 121, could not only require employers engaged in the production of goods for interstate commerce to conform to wage and hour standards, id., at 119-121, but could also require those employers to keep employment records in order to demonstrate compliance with the regulatory scheme, id., at 125. While the Court sustained the former regulation on the alternative ground that the activity it regulated could have a “great effect” on interstate commerce, id., at 122-123, it affirmed the latter on the sole ground that “[t]he require-
As the Court said in the Shreveport Rate Cases, the Necessary and Proper Clause does not give “Congress . . . the authority to regulate the internal commerce of a State, as such,” but it does allow Congress “to take all measures necessary or appropriate to” the effective regulation of the interstate market, “although intrastate transactions . . . may thereby be controlled.” 234 U. S., at 353; see also Jones & Laughlin Steel Corp., 301 U. S., at 38 (the logic of the Shreveport Rate Cases is not limited to instrumentalities of commerce).
II
Today‘s principal dissent objects that, by permitting Congress to regulate activities necessary to effective interstate regulation, the Court reduces Lopez and Morrison to little “more than a drafting guide.” Post, at 46 (opinion of O‘CONNOR, J.). I think that criticism unjustified. Unlike the power to regulate activities that have a substantial effect on interstate commerce, the power to enact laws enabling effective regulation of interstate commerce can only be exercised in conjunction with congressional regulation of an interstate market, and it extends only to those measures necessary to make the interstate regulation effective. As Lopez itself states, and the Court affirms today, Congress may regulate noneconomic intrastate activities only where the failure to do so “could . . . undercut” its regulation of interstate commerce. See Lopez, supra, at 561; ante, at 18, 24-25. This is not a power that threatens to obliterate the line between “what is truly national and what is truly local.” Lopez, supra, at 567-568.
Lopez and Morrison affirm that Congress may not regulate certain “purely local” activity within the States based solely on the attenuated effect that such activity may have in the interstate market. But those decisions do not declare noneconomic intrastate activities to be categorically beyond
And there are other restraints upon the Necessary and Proper Clause authority. As Chief Justice Marshall wrote in McCulloch v. Maryland, even when the end is constitutional and legitimate, the means must be “appropriate” and “plainly adapted” to that end. Id., at 421. Moreover, they may not be otherwise “prohibited” and must be “consistent with the letter and spirit of the constitution.” Ibid. These phrases are not merely hortatory. For example, cases such as Printz v. United States, 521 U. S. 898 (1997), and New York v. United States, 505 U. S. 144 (1992), affirm that a law is not “‘proper for carrying into Execution the Commerce Clause‘” “[w]hen [it] violates [a constitutional] principle of state sovereignty.” Printz, supra, at 923-924; see also New York, supra, at 166.
III
The application of these principles to the case before us is straightforward. In the CSA, Congress has undertaken to extinguish the interstate market in Schedule I controlled substances, including marijuana. The Commerce Clause unquestionably permits this. The power to regulate interstate commerce “extends not only to those regulations which aid,
By this measure, I think the regulation must be sustained. Not only is it impossible to distinguish “controlled substances manufactured and distributed intrastate” from “controlled substances manufactured and distributed interstate,” but it hardly makes sense to speak in such terms. Drugs like marijuana are fungible commodities. As the Court explains, marijuana that is grown at home and possessed for personal use is never more than an instant from the interstate market—and this is so whether or not the possession is for medicinal use or lawful use under the laws of a particular State.3
See ante, at 25-33. Congress need not accept on faith that state law will be effective in maintaining a strict division between a lawful market for “medical” marijuana and the more general marijuana market. See ante, at 30, and n. 38. “To impose on [Congress] the necessity of resorting to means which it cannot control, which another government may furnish or withhold, would render its course precarious, the result of its measures uncertain, and create a dependence on other governments, which might disappoint its most important designs, and is incompatible with the language of the constitution.” McCulloch, 4 Wheat., at 424.
Finally, neither respondents nor the dissenters suggest any violation of state sovereignty of the sort that would render this regulation “inappropriate,” id., at 421—except to argue that the CSA regulates an area typically left to state regulation. See post, at 48, 51 (opinion of O‘CONNOR, J.); post, at 66 (opinion of THOMAS, J.); Brief for Respondents 39-42. That is not enough to render federal regulation an inappropriate means. The Court has repeatedly recognized that, if authorized by the commerce power, Congress may regulate private endeavors “even when [that regulation] may pre-empt express state-law determinations contrary to the result which has commended itself to the collective wisdom of Congress.” National League of Cities v. Usery, 426 U. S. 833, 840 (1976); see Cleveland v. United States, 329 U. S. 14, 19 (1946); McCulloch, supra, at 424. At bottom, respond

I thus agree with the Court that, however the class of regulated activities is subdivided, Congress could reasonably conclude that its objective of prohibiting marijuana from the interstate market “could be undercut” if those activities were excepted from its general scheme of regulation. See Lopez, 514 U. S., at 561. That is sufficient to authorize the application of the CSA to respondents.
JUSTICE O‘CONNOR, with whom THE CHIEF JUSTICE and JUSTICE THOMAS join as to all but Part III, dissenting.
We enforce the “outer limits” of Congress’ Commerce Clause authority not for their own sake, but to protect historic spheres of state sovereignty from excessive federal encroachment and thereby to maintain the distribution of power fundamental to our federalist system of government. United States v. Lopez, 514 U. S. 549, 557 (1995); NLRB v. Jones & Laughlin Steel Corp., 301 U. S. 1, 37 (1937). One of federalism‘s chief virtues, of course, is that it promotes innovation by allowing for the possibility that “a single courageous State may, if its citizens choose, serve as a laboratory; and try novel social and economic experiments without risk to the rest of the country.” New State Ice Co. v. Liebmann, 285 U. S. 262, 311 (1932) (Brandeis, J., dissenting).
This case exemplifies the role of States as laboratories. The States’ core police powers have always included authority to define criminal law and to protect the health, safety, and welfare of their citizens. Brecht v. Abrahamson, 507 U. S. 619, 635 (1993); Whalen v. Roe, 429 U. S. 589, 603, n. 30 (1977). Exercising those powers, California (by ballot initiative and then by legislative codification) has come to its own conclusion about the difficult and sensitive question of whether marijuana should bе available to relieve severe pain and suffering. Today the Court sanctions an application of the federal Controlled Substances Act that extinguishes that experiment, without any proof that the personal cultivation, possession, and use of marijuana for medicinal purposes, if economic activity in the first place, has a substantial effect on interstate commerce and is therefore an appropriate subject of federal regulation. In so doing, the Court announces a rule that gives Congress a perverse incentive to legislate broadly pursuant to the Commerce Clause—nestling questionable assertions of its authority into comprehensive regulatory schemes rather than with precision. That rule and the result it produces in this case are irreconcilable with our decisions in Lopez, supra, and United States v. Morrison, 529 U. S. 598 (2000). Accordingly I dissent.
I
In Lopez, we considered the constitutionality of the Gun-Free School Zones Act of 1990, which made it a federal offense “for any individual knowingly to possess a firearm . . . at a place that the individual knows, or has reasonable cause to believe, is a school zone,”
Our decision about whether gun possession in school zones substantially affected interstate commerce turned on four considerations. Lopez, supra, at 559-567; see also Morrison, supra, at 609-613. First, we observed that our “substantial effects” cases generally have upheld federal regulation of economic activity that affected interstate commerce, but that § 922(q) was a criminal statute having “nothing to do with ‘commerce’ or any sort of economic enterprise.” Lopez, 514 U. S., at 561. In this regard, we also noted that “[s]ection 922(q) is not an essential part of a larger regulation of economic activity, in which the regulatory scheme could be undercut unless the intrastate activity were regulated. It cannot, therefore, be sustained under our cases upholding regulations of activities that arise out of or are connected with a commercial transaction, which viewed in the aggregate, substantially affects intеrstate commerce.” Ibid. Second, we noted that the statute contained no express jurisdictional requirement establishing its connection to interstate commerce. Ibid.
Third, we found telling the absence of legislative findings about the regulated conduct‘s impact on interstate commerce. We explained that while express legislative findings are neither required nor, when provided, dispositive, findings “enable us to evaluate the legislative judgment that the activity in question substantially affect[s] interstate commerce, even though no such substantial effect [is] visible to the naked eye.” Id., at 563. Finally, we rejected as too attenuated the Government‘s argument that firearm possession in school zones could result in violent crime which in turn could
In my view, the case before us is materially indistinguishable from Lopez and Morrison when the same considerations are taken into account.
II
A
What is the relevant conduct subject to Commerce Clause analysis in this case? The Court takes its cues from Congress, applying the above considerations to the activity regulated by the Controlled Substances Act (CSA) in general. The Court‘s decision rests on two facts about the CSA: (1) Congress chose to enact a single statute providing a comprehensive prohibition on the production, distribution, and possession of all controlled substances, and (2) Congress did not distinguish between various forms of intrastate noncommercial cultivation, possession, and use of marijuana. See
The Court‘s principal means of distinguishing Lopez from this case is to observe that the Gun-Free School Zones Act of 1990 was a “brief, single-subject statute,” ante, at 23,
Today‘s decision allows Cоngress to regulate intrastate activity without check, so long as there is some implication by legislative design that regulating intrastate activity is essential (and the Court appears to equate “essential” with “necessary“) to the interstate regulatory scheme. Seizing upon our language in Lopez that the statute prohibiting gun possession in school zones was “not an essential part of a larger regulation of economic activity, in which the regulatory scheme could be undercut unless the intrastate activity were regulated,” 514 U. S., at 561, the Court appears to reason that the placement of local activity in a comprehensive scheme confirms that it is essential to that scheme. Ante, at 24-25. If the Court is right, then Lopez stands for nothing more than a drafting guide: Congress should have described the relevant crime as “transfer or possession of a firearm anywhere in the nation“—thus including commercial and noncommercial activity, and clearly encompassing some activity with assuredly substantial effect on interstate commerce. Had it done so, the majority hints, we would have sustained its authority to regulate possession of firearms in school zones. Furthermore, today‘s decision suggests we would readily sustain a congressional decision to attach the regulation of intrastate activity to a pre-existing comprehensive (or even not-so-comprehensive) scheme. If so, the Court invites increased federal regulation of local activity even if, as it suggests, Congress would not enact a new inter
I cannot agree that our decision in Lopez contemplated such evasive or overbroad legislative strategies with approval. Until today, such arguments have been made only in dissent. See Morrison, 529 U. S., at 657 (BREYER, J., dissenting) (given that Congress can regulate “‘an essential part of a larger regulation of economic activity,‘” “can Congress save the present law by including it, or much of it, in a broader ‘Safe Transport’ or ‘Worker Safety’ act?“). Lopez and Morrison did not indicate that the constitutionality of federal regulation depends on superficial and formalistic distinctions. Likewise I did not understand our discussion of the role of courts in enforcing outer limits of the Commerce Clause for the sake of maintaining the federalist balance our Constitution requires, see Lopez, 514 U. S., at 557; id., at 578 (KENNEDY, J., concurring), as a signal to Congress to enact legislation that is more extensive and more intrusive into the domain of state power. If the Court always defers to Congress as it does today, little may be left to the notion of enumerated powers.
The hard work for courts, then, is to identify objective markers for confining the analysis in Commerce Clause cases. Here, respondents challenge the constitutionality of the CSA as applied to them and those similarly situated. I agree with thе Court that we must look beyond respondents’ own activities. Otherwise, individual litigants could always exempt themselves from Commerce Clause regulation merely by pointing to the obvious—that their personal activities do not have a substantial effect on interstate commerce. See Maryland v. Wirtz, 392 U. S. 183, 193 (1968); Wickard, 317 U. S., at 127-128. The task is to identify a mode of analysis that allows Congress to regulate more than nothing (by declining to reduce each case to its litigants) and less than everything (by declining to let Congress set the
A number of objective markers are available to confine the scope of constitutional review here. Both federal and state legislation—including the CSA itself, the California Compassionate Use Act, and other state medical marijuana legislation—recognize that medical and nonmedical (i. e., recreational) uses of drugs are realistically distinct and can be segregated, and regulate them differently. See
Having thus defined the relevant conduct, we must determine whether, under our precedents, the conduct is economic and, in the aggregate, substantially affects interstate commerce. Even if intrastate cultivation and possession of marijuana for one‘s own medicinal use can properly be characterized as economic, and I question whether it can, it has not been shown that such activity substantially affects interstate commerce. Similarly, it is neither self-evident nor demonstrated that regulating such activity is necessary to the interstate drug control scheme.
The Court‘s definition of economic activity is breathtaking. It defines as economic any activity involving the production, distribution, and consumption of commodities. And it appears to reason that when an interstate market for a commodity exists, regulating the intrastate manufacture or possession of that commodity is constitutional either because that intrastate activity is itself economic, or because regulating it is a rational part of regulating its market. Putting to one side the problem endemic to the Court‘s opinion—the shift in focus from the activity at issue in this case to the entirety of what the CSA regulates, see Lopez, supra, at 565 (“depending on the level of generality, any activity can be looked upon as commercial“)—the Court‘s definition of economic activity for purposes of Commerce Clause jurisprudence threatens to sweep all of productive human activity into federal regulatory reach.
The Court uses a dictionary definition of economics to skirt the real problem of drawing a meaningful line between “what is national and what is local,” Jones & Laughlin Steel, 301 U. S., at 37. It will not do to say that Congress may regulate noncommercial activity simply because it may have an effect on the demand for commercial goods, or because the noncommercial endeavor can, in some sense, substitute for commercial activity. Most commercial goods or services have some sort of privately producible analogue. Home care
In Lopez and Morrison, we suggested that economic activity usually relates directly to commercial activity. See Morrison, 529 U. S., at 611, n. 4 (intrastate activities that have been within Congress’ power to regulate have been “of an apparent commercial character“); Lopez, 514 U. S., at 561 (distinguishing the Gun-Free School Zones Act of 1990 from “activities that arise out of or are connected with a commercial transaction“). The homegrown cultivation and personal possession and use of marijuana for medicinal purposes has no apparent commercial character. Everyone agrees that the marijuana at issue in this case was never in the stream of commerce, and neither were the supplies for growing it. (Marijuana is highly unusual among the substances subject to the CSA in that it can be cultivated without any materials that have traveled in interstate commerce.) Lopez makes clear that possession is not itself commercial activity. Ibid. And respondents have not come into possession by means of any commercial transaction; they have simply grown, in their own homes, marijuana for their own use, without acquiring, buying, selling, or bartering a thing of value. Cf. id., at 583 (KENNEDY, J., concurring) (“The statute now before us forecloses the States from experimenting . . . and it does so by regulating an activity beyond the realm of commerce in the ordinary and usual sense of that term“).
The Court suggests that Wickard, which we have identified as “perhaps the most far reaching example of Commerce Clause authority over intrastate activity,” Lopez, supra, at 560, established federal regulatory power over any home consumption of a commodity for which a national market ex
Even assuming that economic activity is at issue in this case, the Government has made no showing in fact that the possession and use of homegrown marijuana for medical purposes, in California or elsewhere, has a substantial effect on interstate commerce. Similarly, the Government has not shown that regulating such activity is necessary to an interstate regulatory scheme. Whatever the specific theory of “substantial effects” at issue (i. e., whether the activity substantially affects interstate commerce, whether its regulation is necessary to an interstate regulatory scheme, or both), a concern for dual sovereignty requires that Congress’ excursion into the traditional domain of Statеs be justified.
That is why characterizing this as a case about the Necessary and Proper Clause does not change the analysis signifi
There is simply no evidence that homegrown medicinal marijuana users constitute, in the aggregate, a sizable enough class to have a discernable, let alone substantial, impact on the national illicit drug market—or otherwise to threaten the CSA regime. Explicit evidence is helpful when substantial effect is not “visible to the naked eye.” See Lopez, 514 U. S., at 563. And here, in part because common sense suggests that medical marijuana users may be limited in number and that California‘s Compassionate Use Act and similar state legislation may well isolate activities relating to medicinal marijuana from the illicit market, the effect of those activities on interstate drug traffic is not self-evidently substantial.
In this regard, again, this case is readily distinguishable from Wickard. To decide whether the Secretary could regulate local wheat farming, the Court looked to “the actual effects of the activity in question upon interstate commerce.” 317 U. S., at 120. Critically, the Court was able to consider “actual effects” because the parties had “stipulated a summary of the economics of the wheat industry.” Id., at 125. After reviewing in detail the picture of the industry provided in that summary, the Court explained that consumption of homegrown wheat was the most variable factor in the size of the national wheat crop, and that on-site consumption could have the effect of varying the amount of wheat sent to market by as much as 20 percent. Id., at 127. With real numbers at hand, the Wickard Court could easily conclude that “a factor of such volume and variability as home-consumed wheat would have a substantial influence on price and market conditions” nationwide. Id., at 128; see also id., at 128-129 (“This record leaves us in no doubt” about substantial effects).
The Court recognizes that “the record in the Wickard case itself established the causal connection between the produc
They amount to nothing more than a legislative insistence that the regulation of controlled substances must be absolute. They are asserted without any supporting evidence—descriptive, statistical, or otherwise. “[S]imply because Congress may conclude that a particular activity substantially affects interstate commerce does not necessarily make it so.” Hodel v. Virginia Surface Mining & Reclamation Assn., Inc., 452 U. S. 264, 311 (1981) (REHNQUIST, J., concurring in judgment). Indeed, if declarations like these suffice to justify federal regulation, and if the Court today is right about what passes rationality review before us, then our decision in Morrison should have come out the other way. In that case, Congress had supplied numerous findings regarding the impact gender-motivated violence had on the national economy. 529 U. S., at 614; id., at 628-636 (SOUTER, J., dissenting) (chronicling findings). But, recognizing that “‘[w]hether particular operations affect interstate commerce sufficiently to come under the constitutional power of Congress to regulate them is ultimately a judicial rather than a legislative question,‘” we found Congress’ detailed findings inadequate. Id., at 614 (quoting Lopez, supra, at 557, n. 2, in turn quoting Heart of Atlanta Motel, Inc. v. United States, 379 U. S. 241, 273 (1964) (Black, J., сoncurring)). If, as the Court claims, today‘s decision does not
In particular, the CSA‘s introductory declarations are too vague and unspecific to demonstrate that the federal statutory scheme will be undermined if Congress cannot exert power over individuals like respondents. The declarations are not even specific to marijuana. (Facts about substantial effects may be developed in litigation to compensate for the inadequacy of Congress’ findings; in part because this case comes to us from the grant of a preliminary injunction, there has been no such development.) Because here California, like other States, has carved out a limited class of activity for distinct regulation, the inadequacy of the CSA‘s findings is especially glaring. The California Compassionate Use Act exempts from other state drug laws patients and their caregivers “who posses[s] or cultivat[e] marijuana for the personal medical purposes of the patient upon the written or oral recommendation or approval of a physician” to treat a list of serious medical conditions.

We would do well to recall how James Madison, the father of the Constitution, described our system of joint sovereignty to the people of New York: “The powers delegated by the proposed Constitution to the federal government are few and defined. Those which are to remain in the State governments are numerous and indefinite. . . . The powers reserved to the several States will extend to all the objects which, in the ordinary course of affairs, concern the lives, liberties, and properties of the people, and the internal order, improvement, and prosperity of the State.” The Federalist No. 45, pp. 292-293 (C. Rossiter ed. 1961).
Relying on Congress’ abstract assertions, the Court has endorsed making it a federal crime to grow small amounts of marijuana in one‘s own home for one‘s own medicinal use. This overreaching stifles an express choice by some States, concerned for the lives and liberties of their people, to regulate medical marijuana differently. If I were a California citizen, I would not have voted for the medical marijuana ballot initiative; if I were a California legislator I would not have supported the Compassionate Use Act. But whatever the wisdom of California‘s experiment with medical marijuana, the federalism principles that have driven our Commerce Clause cases require that room for experiment be protected in this case. For these reasons I dissent.

As I explained at length in United States v. Lopez, 514 U. S. 549 (1995), the Commerce Clause empowers Congress to regulate the buying and selling of goods and services trafficked across state lines. Id., at 586-589 (concurring opinion). The Clause‘s text, structure, and history all indicate that, at the time of the founding, the term “‘commerce’ consisted of selling, buying, and bartering, as well as transporting for these purposes.” Id., at 585 (THOMAS, J., concurring). Commerce, or trade, stood in contrast to productive activities like manufacturing and agriculture. Id., at 586-587 (THOMAS, J., concurring). Throughout founding-era dictionaries, Madison‘s notes from the Constitutional Convention, The Federalist Papers, and the ratification debates, the term “commerce” is consistently used to mean trade or exchange—not all economic or gainful activity that has some attenuated connection to trade or exchange. Ibid. (THOMAS,

More difficult, however, is whether the CSA is a valid exercise of Congress’ power to enact laws that are “necessary and proper for carrying into Execution” its power to regulate interstate commerce.
In McCulloch v. Maryland, 4 Wheat. 316 (1819), this Court, speaking through Chief Justice Marshall, set forth a test for determining when an Act of Congress is permissible under the Necessary and Proper Clause:
“Let the end be legitimate, let it be within the scope of the constitution, and all means which are appropriate, which are plainly adapted to that end, which are not prohibited, but consist with the letter and spirit of the constitution, are constitutional.” Id., at 421.
To act under the Necessary and Proper Clause, then, Congress must select a means that is “appropriate” and “plainly adapted” to executing an enumerated power; the means cannot be otherwise “prohibited” by the Constitution; and the means cannot be inconsistent with “the letter and spirit of the [C]onstitution.” Ibid.; D. Currie, The Constitution in the Supreme Court: The First Hundred Years 1789-1888, pp. 163-164 (1985). The CSA, as applied to respondents’ conduct, is not a valid exercise of Congress’ power under the Necessary and Proper Clause.
1
Congress has exercised its power over interstate commerce to criminalize trafficking in marijuana across state
On its face, a ban on the intrastate cultivation, possession, and distribution of marijuana may be plainly adapted to stopping the interstate flow of marijuana. Unregulated local growers and users could swell both the supply and the demand sides of the interstate marijuana market, making the market more difficult to regulate. Ante, at 12-13, 22 (majority opinion). But respondents do not challenge the CSA on its face. Instead, they challenge it as applied to their conduct. The question is thus whether the intrastate ban is “necessary and proper” as applied to medical marijuana users like respondents.3
Respondents are not regulable simply because they belong to a large class (local growers and users of marijuana) that
California‘s Compassionate Use Act sets respondents’ conduct apart from other intrastate producers and users of marijuana. The Act channels marijuana use to “seriously ill Californians,”
This class of intrastate users is therefore distinguishable from others. We normally presume that States enforce their own laws, Riley v. National Federation of Blind of N. C., Inc., 487 U. S. 781, 795 (1988), and there is no reason to depart from that presumption here: Nothing suggests that California‘s controls are ineffective. The scant evidence that exists suggests that few people—the vast majority of whom are aged 40 or older—register to use medical marijuana. General Accounting Office, Marijuana: Early Experiences with Four States’ Laws That Allow Use for Medical Purposes 22-23 (Rep. No. 03-189, Nov. 2002), http://www.gao.gov/new.items/d03189.pdf (all Internet materials as visited June 3, 2005, and available in Clerk of Court‘s case file). In part because of the low incidence of medical marijuana use, many law enforcement officials report that the introduction of medical marijuana laws has not affected their law enforcement efforts. Id., at 32.
These controls belie the Government‘s assertion that placing medical marijuana outside the CSA‘s reach “would prevent effective enforcement of the interstate ban on drug trafficking.” Brief for Petitioners 33. Enforcement of the CSA can continue as it did prior to the Compassionate Use Act. Only now, a qualified patient could avoid arrest or prosecution by presenting his identification card to law enforcement officers. In the event that a qualified patient is arrested for possession or his cannabis is seized, he could seek to prove as an affirmative defense that, in conformity with state law, he possessed or cultivated small quantities of marijuana intrastate solely for personal medical use. People v. Mower, 28 Cal. 4th 457, 469-470, 49 P. 3d 1067, 1073-1075 (2002); People v. Trippet, 56 Cal. App. 4th 1532, 1549, 66 Cal. Rptr. 2d 559, 560 (1997). Moreover, under the CSA, certain drugs that present a high risk of abuse and addiction but that nevertheless have an accepted medical use—drugs like mor-
But even assuming that States’ controls allow some seepage of medical marijuana into the illicit drug market, there is a multibillion-dollar interstate market for marijuana. Executive Office of the President, Office of Nat. Drug Control Policy, Marijuana Fact Sheet 5 (Feb. 2004), http://www.whitehousedrugpolicy.gov/publications/factsht/marijuana/index.html. It is difficult to see how this vast market could be affected by diverted medical cannabis, let alone in a way that makes regulating intrastate medical marijuana obviously essential to сontrolling the interstate drug market.
To be sure, Congress declared that state policy would disrupt federal law enforcement. It believed the across-the-board ban essential to policing interstate drug trafficking.
In sum, neither in enacting the CSA nor in defending its application to respondents has the Government offered any obvious reason why banning medical marijuana use is necessary to stem the tide of interstate drug trafficking. Congress’ goal of curtailing the interstate drug trade would not plainly be thwarted if it could not apply the CSA to patients like Monson and Raich. That is, unless Congress’ aim is really to exercise police power of the sort reserved to the States in order to eliminate even the intrastate possession and use of marijuana.
2
Even assuming the CSA‘s ban on locally cultivated and consumed marijuana is “necessary,” that does not mean it is
In Lopez, I argued that allowing Congress to regulate intrastate, noncommercial activity under the Commerce Clause would confer on Congress a general “police power” over the Nation. 514 U. S., at 584, 600 (concurring opinion). This is no less the case if Congress ties its power to the Necessary and Proper Clause rather than the Commerce Clause. When agents from the Drug Enforcement Administration raided Monson‘s home, they seized six cannabis plants. If the Federal Government can regulate growing a half-dozen cannabis plants for personal consumption (not because it is interstate commerce, but because it is inextricably bound up with interstate commerce), then Congress’ Article I powers—as expanded by the Necessary and Proper Clause—have no meaningful limits. Whether Congress aims at the possession of drugs, guns, or any number of other items, it may continue to “appropriat[e] state police powers under the guise of regulating commerce.” United States v. Morrison, 529 U. S. 598, 627 (2000) (THOMAS, J., concurring).
Even if Congress may regulate purely intrastate activity when essential to exercising some enumerated power, see Dewitt, 9 Wall., at 44; but see Barnett, The Original Meaning of the Necessary and Proper Clause, 6 U. Pa. J. Const. L. 183, 186 (2003) (detailing statements by Founders that the Necessary and Proper Clause was not intended to expand the scope of Congress’ enumerated powers), Congress may not use its incidental authority to subvert basic principles of federalism and dual sovereignty. Printz v. United States, 521 U. S. 898, 923-924 (1997); Alden v. Maine, 527 U. S. 706, 732-733 (1999); Garcia v. San Antonio Metropolitan Transit Authority, 469 U. S. 528, 585 (1985) (O‘CONNOR, J., dissenting); The Federalist No. 33, pp. 204-205 (J. Cooke ed. 1961) (A. Hamilton) (hereinafter The Federalist).
II
The majority advances three reasons why the CSA is a legitimate exercise of Congress’ authority under the Commerce Clause: First, respondents’ conduct, taken in the aggregate, may substantially affect interstate commerce, ante, at 22; second, regulation of respondents’ conduct is essential to regulating the interstate marijuana market, ante, at 24-25; and, third, regulation of respondents’ conduct is incidental to regulating the interstate marijuana market, ante, at 22. JUSTICE O‘CONNOR explains why the majority‘s reasons cannot be reconciled with our recent Commerce Clause jurisprudence. The majority‘s justifications, however, suffer from even more fundamental flaws.
A
The majority holds that Congress may regulate intrastate cultivation and possession of medical marijuana under the Commerce Clause, because such conduct arguably has a substantial effect on interstate commerce. The majority‘s decision is further proof that the “substantial effects” test is a “rootless and malleable standard” at odds with the constitutional design. Morrison, supra, at 627 (THOMAS, J., concurring).
The majority‘s treatment of the substantial effects test is rootless, because it is not tethered to either the Commerce Clause or the Necessary and Proper Clause. Under the Commerce Clause, Congress may regulate interstate commerce, not activities that substantially affect interstate commerce, any more than activities that do not fall within, but that affect, the subjects of its other Article I powers. Lopez, 514 U. S., at 589 (THOMAS, J., concurring). Whatever additional latitude the Necessary and Proper Clause affords, supra, at 65-66, the question is whether Congress’ legislation is essential to the regulation of interstate cоmmerce itself—not whether the legislation extends only to economic
The majority‘s treatment of the substantial effects test is malleable, because the majority expands the relevant conduct. By defining the class at a high level of generality (as the intrastate manufacture and possession of marijuana), the majority overlooks that individuals authorized by state law to manufacture and possess medical marijuana exert no demonstrable effect on the interstate drug market. Supra, at 64. The majority ignores that whether a particular activity substantially affects interstate commerce—and thus comes within Congress’ reach on the majority‘s approach—can turn on a number of objective factors, like state action or features of the regulated activity itself. Ante, at 47-48 (O‘CONNOR, J., dissenting). For instance, here, if California and other States are effectively regulating medical marijuana users, then these users have little effect on the interstate drug trade.6
The substantial effects test is easily manipulated for another reason. This Court has never held that Congress can
Moreover, even a Court interested more in the modern than the original understanding of the Constitution ought to resolve cases based on the meaning of words that are actually in the document. Congress is authorized to regulate “Commerce,” and respondents’ conduct does not qualify under any definition of that term.7 The majority‘s opinion8
The majority‘s rewriting of the Commerce Clause seems to be rooted in the belief that, unless the Commerce Clause covers the entire web of human activity, Congress will be left powerless to regulate the national economy effectively. Ante, at 18-19; Lopez, 514 U. S., at 573-574 (KENNEDY, J., concurring). The interconnectedness of economic activity is not a modern phenomenon unfamiliar to the Framers. Id., at 590-593 (THOMAS, J., concurring); Letter from J. Madison to S. Roane (Sept. 2, 1819), in 3 The Founders’ Constitution 259-260 (P. Kurland & R. Lerner eds. 1987). Moreover, the Framers understood what the majority does not appear to fully appreciate: There is a danger to concentrating too much, as well as too little, power in the Federal Government. This Court has carefully avoided stripping Congress of its ability to regulate interstate commerce, but it has casually allowed the Federal Government to strip States of their ability to regulate intrastate commerce—not to mention a host of local activities, like mere drug possession, that are not commercial.
One searches the Court‘s opinion in vain for any hint of what aspect of American life is reserved to the States. Yet this Court knows that “[t]he Constitution created a Federal Government of limited powers.” New York v. United States, 505 U. S. 144, 155 (1992) (quoting Gregory v. Ashcroft, tween different parts of the same country“); Webster‘s 3d 456 (“the exchange or buying and selling of commodities esp. on a large scale and involving transportation from place to place“).

The majority also inconsistently contends that regulating respondents’ conduct is both incidental and essential to a comprehensive legislative scheme. Ante, at 22, 24-25. I have already explained why the CSA‘s ban on local activity is not essential. Supra, at 64. However, the majority further claims that, because the CSA covers a great deal of interstate commerce, it “is of no moment” if it also “ensnares some purely intrastate activity.” Ante, at 22. So long as Congress casts its net broadly over an interstate market, according to the majority, it is free to regulate interstate and intrastate activity alike. This cannot be justified under either the Commerce Clause or the Necessary and Proper Clause. If the activity is purely intrastate, then it may not be regulated under the Commerce Clause. And if the regulation of the intrastate activity is purely incidental, then it may not be regulated under the Necessary and Proper Clause.
Nevertheless, the majority terms this the “pivotal” distinction between the present case and Lopez and Morrison. Ante, at 23. In Lopez and Morrison, the parties asserted facial challenges, claiming “that a particular statute or provision fell outside Congress’ commerce power in its entirety.” Ante, at 23. Here, by contrast, respondents claim only that the CSA falls outside Congress’ commerce power as applied
It is true that if respondents’ conduct is part of a “class of activities . . . and that class is within the reach of federal power,” Perez, supra, at 154 (emphasis deleted), then respondents may not point to the de minimis effect of their own personal conduct on the interstate drug market, Wirtz, supra, at 196, n. 27. Ante, at 47 (O‘CONNOR, J., dissenting). But that begs the question at issue: whether respondents’ “class of activities” is “within the reach of federal power,” which depends in turn on whether the class is defined at a low or a high level of generality. Supra, at 61-62. If medical marijuana patients like Monson and Raich largely stand outside the interstate drug market, then courts must excise them from the CSA‘s coverage. Congress expressly provided that if “a provision [of the CSA] is held invalid in one or more of its applications, the provision shall remain in effect in all its valid applications that are severable.”
Even in the absence of an express severability provision, it is implausible that this Court could set aside entire portions of the United States Code as outside Congress’ power in Lopez and Morrison, but it cannot engage in the more restrained practice of invalidating particular applications of the CSA that are beyond Congress’ power. This Court has regularly entertained as-applied challenges under constitutional provisions, see United States v. Raines, 362 U. S. 17, 20-21 (1960), including the Commerce Clause, see Katzenbach v. McClung, 379 U. S. 294, 295 (1964); Heart of Atlanta
If the majority is correct that Lopez and Morrison are distinct because they were facial challenges to “particular statute[s] or provision[s],” ante, at 23, then congressional power turns on the manner in which Congress packages legislation. Under the majority‘s reasoning, Congress could not enact—either as a single-subject statute or as a separate provision in the CSA—a prohibition on the intrastate possession or cultivation of marijuana. Nor could it enact an intrastate ban simply to supplement existing drug regulations. However, that same prohibition is perfectly constitutional when integrated into a piece of legislation that reaches other regulable conduct. Lopez, 514 U. S., at 600-601 (THOMAS, J., concurring).
Finally, the majority‘s view—that because some of the CSA‘s applications are constitutional, they must all be constitutional—undermines its reliance on the substantial effects test. The intrastate conduct swept within a general regulatory scheme may or may not have a substantial effect on the relevant interstate market. “[O]ne always can draw the circle broadly enough to cover an activity that, when taken in isolation, would not have substantial effects on commerce.” Id., at 600 (THOMAS, J., concurring). The breadth of legislation that Congress enacts says nothing about whether the intrastate activity substantially affects interstate commerce, let alone whether it is necessary to the scheme. Because medical marijuana users in California and elsewhere are not placing substantial amounts of cannabis

The majority prevents States like California from devising drug policies that they have concluded provide much-needed respite to the seriously ill. It does so without any serious inquiry into the necessity of federal regulation or the propriety of “displac[ing] state regulation in areas of traditional state concern,” id., at 583 (KENNEDY, J., concurring). The majority‘s rush to embrace federal power “is especially unfortunate given the importance of showing respect for the sovereign States that comprise our Federal Union.” United States v. Oakland Cannabis Buyers’ Cooperative, 532 U. S. 483, 502 (2001) (STEVENS, J., concurring in judgment). Our federalist system, properly understood, allows California and a growing number of other States to decide for themselves how to safeguard the health and welfare of their citizens. I would affirm the judgment of the Court of Appeals.
I respectfully dissent.
