MEMORANDUM OPINION AND ORDER
Defendants move to dismiss this action contending that the definition of a controlled substance analogue as applied here is unconstitutionally vague. 21 U.S.C. § 802(32)(A). Hearing on the motion was held on November 19, 1992. Because the definition of “analogue” as applied here provides neither fair warning nor effective safeguards against arbitrary enforcement, it is void for vagueness. Defendants’ motion is granted and this action is dismissed.
Defendants are charged in a four cotint indictment with distribution of alphaethyl-tryptamine (AET), in violation of 21 U.S.C. §§ 813, 841, and 846. AET is not a scheduled controlled substance. Rather, .the indictment alleges that it is a “controlled substance analogue” having a substantially similar chemical structure to dimethyltryp-tamine (DMT) and diethyltryptamine (DET), both schedule I controlled substances. This is the first case where the government has prosecuted the distribution of AET under the controlled substance analogue statute.
Unless otherwise noted, the unique operative facts underlying this prosecution are undisputed. AET is an anti-depressant developed and marketed in 1960 by the Upjohn Chemical Company as “Monase.” After several years it was discovered to have toxic side effects in some patients and it was taken off the market. However, to this day, the public can purchase AET without any restrictions directly from two chemical manufacturers. Defendants here allegedly purchased AET from Sigma Chemical Company and it was allegedly delivered to. them through the U.S. mails.
There is great diversity of opinion whether AET’s chemical structure is substantially similar to DMT or DET so as to constitute a controlled substance analogue. See, infra, Section I. Indeed, Robert K. Sanger, chief of DEA’s western field laboratory, stated in a 1990 DEA memorandum “there is a great diversity of opinion whether this material is controlled as an analogue under the 1986 Act.”
Defendants presented the affidavit of Drs. James Ruth and Charles Duncan, who are both Ph.D. neuropharmacologists at the University of Colorado School of Pharmacy. Dr. Ruth also testified at the hearing on the motion. These experts conclude that AET is not substantially similar to DMT or DET, and that AET may not be derived by minor manipulations or tinkering with the DMT or DET molecule. Further, they conclude that AET does not have a hallucinogenic or stimulant effect on the central nervous system that is substantially similar to DMT or DET. Ruth testified that the mechanism through which AET effects the central nervous system is different than the mechanism of hallueinogen-ics and stimulants. Finally, they believe that other scientists in their field would agree with their conclusions.
The government presented a contrary scientific opinion. Drug Enforcement Administration (DEA) chemist Frank Sapienza testified that AET is a controlled substance analogue that has a substantially similar *234 chemical structure. Sapienza agrees that AET cannot be synthesized from either the DMT or the DET molecule. Rather, he concludes that AET is substantially similar to DMT and DET because they all share a structural family root, the tryptamine family, and they all produce some degree of hallucinogenic and stimulant activity. However, another DEA chemist, Roger Ely, testified at the hearing that AET’s chemical structure is not substantially similar to DMT or DET. Ely focused on another part of the AET molecule, the amine group, and noted that AET is a primary amine while DMT and DET are tertiary amines. Sapienza concluded that reputable scientists in this field disagree even on the methodology applicable to determine structural similarity.
Defendant Forbes was arrested by Boulder, Colorado police in 1990 for the distribution of AET, among other drugs. Because Colorado did not have an analogue statute, the Boulder County district attorney referred the prosecution of the AET sale to the United States Attorney’s office. Although subject to dispute, I find from the evidence that assistant U.S. attorney Ken Buck declined to prosecute because he determined that AET was not a controlled substance analogue. I further find from the evidence that, through discovery in his state case, Forbes obtained a copy of the DEA report stating that Buck declined to prosecute due to the conflict within the government as to AET’s structural similarity to DMT and DET. He also obtained a copy of Ely’s report on which Buck’s decision was based.
Defendants now move to dismiss this prosecution as violating the due process clause of the Fifth Amendment to the United States Constitution. They argue that the statutory definition of a controlled substance analogue as applied to AET under the circumstances of this case is unconstitutionally vague. Because this argument is premised upon a disputed question of statutory construction, I will address that issue first and then turn to the vagueness question.
I.
Defendants are charged in this case with violations of 21 U.S.C. § 813 which provides that “A controlled substance analogue shall, to the extent intended for human consumption, be treated ... as a controlled substance in schedule I.” The statute defines controlled substance analogue as:
(32)(A) Except as provided in subpara-graph (B), the term “controlled substance analogue” means a substance—
(i) the chemical structure of which is substantially similar to the chemical structure of a controlled substance in schedule I or II;
(ii) which has a stimulant, depressant, or hallucinogenic effect on the central nervous system that is substantially similar to or greater than [such effect] of a controlled substance in schedule I or II; or
(iii) with respect to a particular person, which such person represents or intends to have a stimulant, depressant, or hallucinogenic effect on the central nervous system that is substantially similar to or greater than [such effect] of a controlled substance in schedule I or II.
21 U.S.C. § 802(32), (emphasis added).
Defendants contend that this section requires a two-pronged definition. The first prong requires a substantially similar chemical structure. The second prong requires either a substantially similar effect on the human nervous system or the intent to have such an effect. The government argues that a substance may be an analogue if it satisfies any of the three clauses. I agree with defendants.
The goal of statutory construction is to effectuate the intent and purpose of Congress.
Rocky Mountain Oil & Gas Assoc. v. Watt,
The government’s reading of the analogue definition has superficial appeal. As a matter of simple grammar, when an “or” is placed before the last term in a series, each term in the series is usually intended to be disjunctive. Under this reading, AET would be an analogue if it satisfies any of the three clauses. However, this reading ignores other grammatical principles that apply in favor of defendants’ construction. The operative segments of clauses (ii) and (iii) both begin with the word “which”, signaling the start of a dependent relative clause modifying a precedent noun. In each case, the precedent noun is “chemical structure” found in clause (i). Because both clauses (ii) and (iii) can be read to modify clause (i), the statutory language can be fairly read as requiring the two-pronged definition asserted by defendants.
See, First Charter Financial Corp. v. U.S.,
Defendants’ reading is also bolstered by a deeply rooted rule of statutory construction. A statute must be construed to avoid unintended or absurd results.
American Tobacco Co. v. Patterson,
Further, defendants’ construction is supported by legislative history. In July, 1985, the Senate began consideration of the “Designer Drug Enforcement Act of 1985” (S.1417, later redesignated the “Controlled Substance Analog Enforcement Act of 1985”, S.1437). The bill’s stated purpose was “to prohibit persons who specifically set out to manufacture or to distribute drugs which are substantially similar to the most dangerous controlled substances from engaging in this activity.” S.Rep. No. 196, 99th Cong., 1st Sess. 5 (1985). The Senate Judiciary Committee reported that law enforcement authorities find themselves one step behind underground chemists who slightly alter the molecular structure of controlled substances to create new drugs. Id. at 1-2. The Senate proposed a two-part definition of the term analogue: either the substance has a substantially similar chemical structure or it was “specifically designed” to produce an effect substantially similar to schedule I or II drugs.
In July, 1986, the House of Representatives considered the Designer Drug Enforcement Act of 1986 (H.R. 5246). As with the Senate, the House bill focused on underground chemists who seek to evade the drug laws by slightly altering a controlled substance. H.R.Rep. No. 948, 99th Cong., 2d Sess. 4 (1986). The House proposed a two-pronged definition of analogue that is virtually identical to the construction advocated by defendants here. The House bill contained the same three clauses as the current statute, but added the word “and” after clause (i).
The term “controlled substance analogue” is defined to conform as closely as possible to the policy of the Controlled Substances Act by requiring a chemical relationship to a substance which is controlled ... and either the existence of some stimulant, depressant, or hallucinogenic effect on the central nervous system, or a representation or intent that the substance have a stimulant, depressant, or hallucinogenic effect substantial *236 ly similar to, or greater than, such effect of any controlled substance.
Id. at 2, (emphasis added). The report illustrates the point with coffee. “Coffee, for example, has a stimulant effect on the central nervous system, but it is not chemically substantially similar to' a controlled substance.” Id. at 7.
Congress ultimately adopted the analogue statute as part of the comprehensive “Anti-Drug Abuse Act of 1986” (H.R. 5484). Inexplicably, the analogue definition enacted by Congress dropped the word “and” after clause (i). Otherwise, that definition and the two-pronged definition considered by the House are virtually identical. I consider the House report to be persuasive legislative history as to Congress’ intent underlying its definition of a controlled substance analogue.
The legislative history thus clearly supports defendants’ construction. The analogue statute is directed at underground chemists who tinker with the molecular structure of controlled substances to create new drugs that are not scheduled. If a substance could be an analogue without a substantially similar chemical structure, Congress’ stated purpose would be significantly expanded. Moreover, by essentially adopting the House definition, Congress evidenced its intent to require a two-pronged definition.
Additionally, the government and defense experts who testified agree that the question of structural similarity must, in part, be evaluated in conjunction with the molecule’s hallucinogenic and stimulant activity. Because structurally similar substances have similar pharmacological effects on the central nervous system, a finding of such similar effects is some indication that the molecular structures should be classified as substantially similar. The scientific interdependence of molecular structure and effect on the central nervous system is consonant with the legislative history evidencing congressional intent to establish a dependent, two-prong test.
Finally, courts must construe criminal statutes narrowly in favor of lenity to the accused.
United States v. Enmons,
Therefore, I hold that a substance may be a controlled substance analogue only if it satisfies clause (i) and clauses (ii) or (iii).
II.
Defendants argue that the statutory definition of controlled substance analogue is unconstitutionally vague as applied to AET under the circumstances of this case. While not contesting defendants’ characterization of scientific opinion, the government argues that whether AET is a controlled substance analogue is a question for the trier of fact. It further argues that the phrase “substantially similar” is not unconstitutionally vague.
The void for vagueness doctrine stems from the Fifth Amendment’s constitutional guarantee of due process.
Connally v. General Constr. Co.,
Vague laws offend several important values. First, because we assume that man is free to steer between lawful and unlawful conduct, we insist that the laws give the person of ordinary intelligence a reasonable opportunity to know what is *237 prohibited, so that he may act accordingly. Vague laws may trap the innocent by not providing fair warning. Second, if arbitrary and discriminatory enforcement is to be prevented, laws must provide explicit standards for those who apply them. A vague law impermissibly delegates basic policy matters to policemen, judges, and juries for resolution on an ad hoc and subjective basis, with the attendant dangers of arbitrary and discriminatory applications, (footnotes and citations omitted).
Grayned v. City of Rockford,
Defendants contrast this case with two recent decisions which together hold that a statute is not vague if the meaning of the statutory standard is generally accepted when applied to a particular situation. In
U.S. v. Jackson,
In
U.S. v. Vasarajs,
Here, the relevant statutory standard is the phrase “the chemical structure of which is substantially similar to the chemical structure of a controlled substance in schedule I or II.” Clearly, this standard incorporates a scientific term of art and requires reference to the appropriate fields of chemistry and pharmacology to determine its meaning. Although the “substantially similar” language may be generally susceptible to adequate definition, it runs afoul of the vagueness doctrine when it is applied to AET under the circumstances of this case.
It is undisputed that there is no scientific consensus whether AET has a chemical structure that is substantially similar to DMT or DET. The government’s own chemists cannot agree on this point, and the U.S. attorneys’ office once before declined to prosecute defendant Forbes for the very conduct that is charged here. The. scientific community cannot even agree on a methodology to use to determine structural similarity. Thus, unlike the meaning of cocaine base or the boundaries of a military reservation, a defendant cannot determine in advance of his contemplated conduct whether AET is or is not substantially similar to a controlled substance.
See, Gentile v. State Bar of Nevada,
— U.S. —, — - —,
*238
Moreover, the definition of controlled substance analogue does not require any scienter—a defendant does not have to “know” that a substance has a substantially similar chemical structure to an illegal drug.
See, The Village of Hoffman Estates v. The Flipside,
This conclusion is buttressed by the announced purpose of the controlled substance analogue statute. Congress declared that the purpose of the statute is to attack underground chemists who tinker with the molecules of controlled substances to create new drugs that are not yet illegal. None of the defendants here engaged in such conduct. They are not chemists who created or marketed a new designer drug. Rather, they allegedly purchased and distributed a substance that pre-existed the drugs to which it is a purported analogue. Under these circumstances, defendants had no fair warning that their alleged conduct was proscribed.
Nevertheless, the government argues that whether AET is a controlled substance analogue is a question of fact for the jury that cannot be resolved by the court before trial. Of course, whether AET is a controlled substance analogue would ultimately be a question for the trier of fact. However, the question posed by defendants’ motion is not whether AET is an analogue of DMT or DET—the dispositive issue is whether the statutory definition as applied to AET under the circumstances here is unconstitutionally vague. Next, the government argues that the phrase substantially similar is not vague and has been upheld in other contexts. Again, the government misstates the relevant question. While substantially similar may be adequate to pass constitutional muster in other contexts, it does not when applied to AET under the circumstances of this case.
Further, the government’s reliance on
United States v. Granberry,
[T]he term “controlled substance analogue” in § 813 is clearly and specifically defined.... It provides adequate notice of what conduct is prohibited. The statute makes plain that drugs which have been chemically designed to be similar to controlled substances, but which are not themselves listed on the controlled substance schedules, will nonetheless be considered as schedule I substances....
Granberry,
Lastly, the government relies on recent Tenth Circuit law holding “the mere fact that different minds may reach different results when seeking to determine whether a given object falls within the statutory definition of drug paraphernalia does not render the statute void for vagueness.”
U.S. v. Murphy,
Perhaps more importantly in this case, the analogue definition as applied to AET *239 is so vague as to permit arbitrary enforcement. In 1990, the DEA investigated defendant Forbes for allegedly distributing AET, but the U.S. attorneys’ office declined to prosecute, citing DEA chemist Roger Ely’s conclusion that AET is not substantially similar to DMT or DET. Now, in 1992, Forbes is prosecuted by the same office for the same alleged offense. Nothing changed in the intervening two years except the personalities of the government prosecutors and their hand-picked DEA chemists.
This prosecution illustrates precisely the evils attending delegation of basic policy decisions for ad hoc, subjective resolution by those who wield prosecutorial power.
Grayned,
Although I recognize the strong presumption favoring constitutionality of statutes and requiring courts to construe statutes in a constitutional manner, there is no construction possible here that would satisfy due process without re-writing the statute. See, Murphy, supra, at 505. Thus, for the reasons set out above, I conclude that defendants have clearly and convincingly rebutted the presumption of constitutionality in this case.
I hold that the definition of controlled substance analogue as applied to AET under the unique facts here is unconstitutionally vague. Without doubt, it provides neither fair warning nor effective safeguards against arbitrary enforcement.
Accordingly, IT IS ORDERED THAT:
(1) Defendants’ motion to dismiss is GRANTED; and,
(2) This action shall be DISMISSED.
