Opinion
Following the enactment of Proposition 36, the “Substance Abuse and Crime Prevention Act of 2000,” which took effect July 1, 2001, a defendant who has been convicted of a “nonviolent drug possession offense” must receive probation and diversion into a drug treatment program, and may not be sentenced to incarceration as an additional *1273 term of probation. (Pen. Code, § 1210.1, subd. (a).) 1 A defendant is ineligible for probation and diversion to such a program, however, if he or she has been “convicted in the same proceeding of a misdemeanor not related to the use of drugs or any felony.” (Pen. Code, § 1210.1, subd. (b)(2).) 2 An offense is defined as one “not related to the use of drugs” if it does not involve the defendant’s “simple possession or use” of drugs or drug paraphernalia, presence where drugs are being used, or failure to register as a drug offender, or any similar activity. (§ 1210, subd. (d).)
The issue in the present case is whether defendant, who was convicted of transporting a controlled substance (methamphetamine), a felony, together with driving a vehicle while under the influence of a controlled substance, a misdemeanor, has been “convicted in the same proceeding of a misdemeanor not related to the use of drugs,” within the meaning of section 1210.1, subdivision (b)(2) and section 1210, subdivision (d). We conclude that the misdemeanor of driving a vehicle while under the influence of a controlled substance is “a misdemeanor not related to the use of drags” within the meaning of those provisions, and that therefore section 1210.1, subdivision (a) is inapplicable to defendant. Accordingly, we affirm the judgment of the Court of Appeal upholding the trial court’s determination that defendant was not entitled to probation and drug treatment diversion under Proposition 36.
I
At approximately 10:40 p.m. on March 17, 2001, a police officer observed a person driving a vehicle (with two passengers) down the center of a road, straddling the center divider, for approximately one block. The officer, suspecting the driver was under the influence of drags or alcohol, made a traffic stop.
The driver, defendant Michelle Elaine Canty, appeared to be under the influence of alcohol or drags, and admitted to the officer that she had ingested methamphetamine, which she also had provided to her two passengers, earlier that evening. The officer conducted a search, discovered that defendant possessed two grams of methamphetamine, and arrested her. Later tests confirmed she was under the influence of methamphetamine.
Defendant was charged with several felonies, including transportation, possession for sale, and being under the influence of methamphetamine, as *1274 well as several misdemeanors, including driving while under the influence of alcohol and a drug. It further was alleged that defendant had served a prison term in 1996 for possession of methamphetamine.
On June 19, 2001, defendant pleaded guilty to transportation of methamphetamine (Health & Saf. Code, § 11379, subd. (a)), a felony, and to driving a vehicle while under the influence of alcohol or drugs (Veh. Code, § 23152, subd. (a)), a misdemeanor. The remaining charges were dismissed.
Subsequently, Proposition 36 having become effective on July 1, 2001, the trial court referred the matter to the probation department to determine whether, pursuant to section 1210.1, subdivision (a), defendant was entitled to probation and diversion to a drug treatment program. The probation report, noting that defendant had suffered several prior convictions, recommended that she not be granted probation under Proposition 36 or any other provision, and that she serve a term in state prison for the felony drug conviction.
Defendant and her mother both submitted written requests that the trial court order that defendant receive drug treatment. Defendant’s letter explained that she previously had attended a drug treatment program that had enabled her to “stay clean” for more than two years, and that she had resumed drug use only recently.
On August 7, 2001, at the sentencing hearing, the trial court denied defendant’s request to be placed on probation and be diverted to a drug treatment program. The trial court determined that defendant was ineligible both because her convictions preceded the effective date of section 1210.1 and because her conviction for driving while under the influence was a “misdemeanor not related to the use of drugs” within the meaning of section 1210.1, subdivision (b)(2).
The trial court imposed and suspended execution of a sentence of two years in state prison for defendant’s conviction of transporting methamphetamine, placed her on five years’ formal probation requiring service of 90 days in county jail, and ordered her to pay restitution and to register as a controlled substance offender. The trial court also imposed a term of six months in county jail for defendant’s conviction of driving a vehicle while under the influence of drugs. Defendant timely filed a notice of reasonable grounds for an appeal based upon the sentence she received, and the trial court issued a certificate of probable cause (§ 1237.5).
The Court of Appeal accepted a concession by the Attorney General that the circumstance of defendant’s offenses having predated the enactment of Proposition 36 did not render that measure inapplicable. The appellate court *1275 affirmed the trial court’s ruling that defendant was not entitled to be sentenced under the provisions of Proposition 36, concluding that defendant’s conviction for driving while under the influence of drugs was a “misdemeanor not related to the use of drugs” within the meaning of section 1210.1, subdivision (b)(2), and thus precluded probation and diversion to a drug treatment program. We granted defendant’s petition for review.

Proposition 36 mandates probation and diversion to a drug treatment program for those offenders whose illegal conduct is confined to using, possessing, or transporting a controlled substance. Its provisions outline “an alternative sentencing scheme” for persons convicted of certain drug offenses.
(In re Varnell
(2003)
Section 1210.1, subdivision (a) provides in relevant part that subject to the exceptions set forth, “any person convicted of a nonviolent drug possession offense shall receive probation. As a condition of probation the court shall require participation in and completion of an appropriate drug treatment program.” Section 1210, subdivision (a) defines a “drug possession offense,” as used in section 1210.1, as “the unlawful personal use, possession for personal use, or transportation for personal use of any controlled substance identified in Section 11054, 11055, 11056, 11057 or 11058 of the Health and Safety Code, or the offense of being under the influence of a controlled substance in violation of Section 11550 of the Health and Safety Code. The term ‘nonviolent drug possession offense’ does not include the possession for sale, production, or manufacturing of any controlled substance and does not include violations of Section 4573.6 or 4573.8.” (As amended Stats. 2003, ch. 155, § 1.)
Section 1210.1, subdivision (b) describes those defendants who are 'disqualified from receiving mandatory probation and diversion pursuant to section 1210.1, subdivision (a). Section 1210.1, subdivision (b)(1) generally disqualifies persons previously convicted of serious or violent felonies. Section 1210.1, subdivision (b)(2) disqualifies “[a]ny defendant who, in addition to one or more nonviolent drug possession offenses, has been convicted in the same proceeding of a misdemeanor not related to the use of drugs or any felony.” (Italics added.) Section 1210, subdivision (d) defines the term “misdemeanor not related to the use of drugs” as “a misdemeanor that does not involve (1) the simple possession or use of drugs or drug paraphernalia, being present where drugs are used, or failure to register as a drug offender, or (2) any activity similar to those listed in paragraph (1).” (Italics added.)
*1276 Defendant contends that misdemeanor driving while under the influence of drugs constitutes an activity similar to “simple possession or use of drugs or drug paraphernalia, being present where drugs are used, or failure to register as a drug offender,” and therefore falls within the category of offenses that, as described in section 1210, subdivision (d)(2), do not disqualify a defendant from receiving probation and diversion to a drug treatment program in lieu of traditional punishment. Defendant observes that misdemeanor driving while under the influence of drugs is not similar to those offenses (such as selling or distributing drugs) listed in section 1210, subdivision (a)—offenses that are not considered to be among the “nonviolent drug possession offense[s]” that entitle a defendant to such probation and diversion.
A
In interpreting a voter initiative such as Proposition 36, we apply the same principles that govern the construction of a statute.
(Robert L. v. Superior Court
(2003)
Our first task is to examine the language of the statute enacted as an initiative, giving the words their usual, ordinary meaning.
(Curie, supra,
The language is construed in the context of the statute as a whole and the overall statutoiy scheme, and we give “significance to every word, phrase, sentence, and part of an act in pursuance of the legislative purpose. [Citation.]”
(Curie, supra,
“If the Legislature has provided an express definition of a term, that definition ordinarily is binding on the courts.”
(Curie, supra,
We therefore apply the principles that pertain where statutory ambiguity exists, adopting the interpretation that leads to a more reasonable result.
(Deukmejian, supra,
We also consider that, under the traditional “rule of lenity,” language in a penal statute that truly is susceptible of more than one reasonable construction in meaning or application ordinarily is construed in the manner that is more favorable to the defendant.
(People
v.
Avery
(2002)
*1278 B

Defendant points out that “being under the influence of drugs” in violation of Health and Safety Code section 11550 constitutes a “nonviolent drug possession offense” pursuant to section 1210, subdivision (a). She urges that the misdemeanor of driving while under the influence of drugs should be equated with that of being under the influence of drugs or of possessing drugs. Defendant reasons that the use of drugs is integral to each offense.
In response to the observation of the Court of Appeal that the driving offense involves public safety, whereas simple use or possession does not, defendant asserts that the presence of a risk to public safety is not the feature that separates qualifying from nonqualifying offenses. Defendant urges that a person may be found guilty of driving while under the influence of drugs despite having driven a minimal distance and not having exposed others to actual danger. A person may be convicted of certain other offenses, such as transportation of drugs, and still receive diversion under section 1210.1, even though these latter offenses actually pose a greater danger to the public than driving while under the influence of drugs.
We cannot agree with defendant’s equation of the two offenses, for several reasons. As an initial matter, the offenses of being under the influence of drugs and driving while under the influence of drugs differ significantly in the level or degree of impairment required for conviction. One may be guilty of
being
under the influence of drugs in violation of Health and Safety Code section 11550 by being in that state in any detectable manner: “ ‘The symptoms of being under the influence within the meaning of that statute are not confined to those commensurate with misbehavior, nor to those which demonstrate impairment of physical or mental ability.’ ”
(People v. Enriquez
(1996)
By contrast, for a defendant to be guilty of
driving
while under the influence of drugs in violation of Vehicle Code section 23152, subdivision (a), “ ‘the . . . drug(s) must have so far affected the nervous system, the brain, or muscles [of the individual] as to impair to an appreciable degree
the ability to operate a vehicle
in a manner like that of an ordinarily prudent and cautious person in full possession of his faculties. [Citations.]’ ”
(People v. Enriquez, supra,
Second, the conduct that is the central focus of each statute is not similar. The permissible drug-related misdemeanors described in section 1210, subdivision (d)(1)—simple possession or use of drugs or drug paraphernalia, presence where drugs are used, or failure to register as a drug offender—share an emphasis on the individual offender’s own private involvement with the proscribed substance. By contrast, the driving-while-under-the-influence misdemeanor described in Vehicle Code section 23152 primarily is concerned not with the offender’s use of the proscribed substance, but with his or her use of a motor vehicle. (See
Byrd
v.
Municipal Court, supra,
Third, as a related point, the interest that society seeks to protect by criminalizing each activity is not identical. In proscribing
“being-
under the influence,” the statute’s legislative purpose primarily is to
protect the user
from the consequences—such as addiction to the substance used—of his or her own conduct. (See
Bosco
v.
Justice Court
(1978)
Our comparative analysis of these provisions leads us to conclude, in construing the statutory definition of the term “misdemeanor not related to the use of drugs” as an offense other than those set forth in section 1210, subdivision (d), that the misdemeanor of driving while under the influence is *1280 not an activity similar to those misdemeanors involving the simple possession, use, or presence at the use of drags, or the failure to register one’s status as a drag offender.
2
Because the most reasonable interpretation of a provision may be reflected, in part, by evidence of the enacting body’s intent beyond the statutory language itself, in its history and background (Birkett, supra,
In approving the “Drags, Probation and Treatment Program” initiative on November 7, 2000, the electorate adopted uncodified findings and declarations that treatment for substance abuse is “a proven public safety and health measure,” and that a similar proposition had been endorsed by voters in Arizona with proven success in enhancing public safety. 3 In addition, the electorate expressed the purpose and intent to divert nonviolent defendants charged with “simple drug possession and drag use offenses” from incarceration into community-based substance abuse treatment programs, to halt the expenditure of hundreds of millions of dollars to incarcerate and re-incarcerate “nonviolent drag users” better served by community-based treatment, to enhance public safety by reducing drag-related crime and reserving *1281 jails and prisons for serious and violent offenders, and to improve public health by treatment of drug abuse and dependence through proven and effective drug treatment strategies. (Prop. 36, § 3, subds. (a)-(c); see Historical and Statutory Notes, 51 West’s Ann. Pen. Code, supra, foil. § 1210, p. 249.)
The purpose and intent expressed in the preamble to these statutes tends to reinforce the conclusion that misdemeanor driving while under the influence of drugs is not an activity similar to the conduct that underlies those misdemeanors that merely involve personal interaction with drugs, described in section 1210, subdivision (d). As explained more fully below, the statutes that prohibit driving while under the influence of drugs contemplate graduated levels of incarceration as well as other restrictions, such as suspension or revocation of a driver’s license, and thus do not appear to be “simple” offenses for purposes of the probation and diversion statutes.
In construing these statutes, we also may refer to “other indicia of the voters’ intent, particularly the analyses and arguments contained in the official ballot pamphlet. [Citation.]”
(Rizo, supra,
*1282 In view of the express advice given the voters that Proposition 36 was strictly limited—affecting “only simple drug possession,” and changing “[n]o other criminal laws” (Ballot Pamp., Gen. Elec. (Nov. 7, 2000) argument in favor of Prop. 36, p. 26)—we must assume that the voters did not intend to amend other criminal statutes. If we were to interpret section 1210.1, subdivision (b)(2) not to preclude a defendant convicted of misdemeanor driving while under the influence of drugs from receiving probation and drug treatment under section 1210.1, subdivision (a), however, such a change in a statutory scheme would result.
At present, the Vehicle Code imposes increasingly harsh punishments on those drivers who reoffend in violation of its provisions. Those statutes impose a 96-hour jail term for a first conviction (Veh. Code, § 23536, subd. (a)), a 90-day jail term for a second conviction within seven years (Veh. Code, § 23540), a 120-day jail term for a third conviction within seven years (Veh. Code, § 23546), and a term of not less than 180 days in jail (or a term in state prison) for a fourth conviction within' seven years (Veh. Code, § 23550; see
People
v.
Casillas
(2001)
Pursuant to Proposition 36 (§ 1210.1, subd. (d)(1)), if the court finds that a defendant has completed an appropriate drug treatment program, the court “shall” expunge the conviction from the defendant’s record. Thus, such a defendant’s subsequent conviction of misdemeanor driving while under the influence of drugs would be treated as a first offense. That result would be contrary to the evident intent of the Vehicle Code—which clearly is to increase, with each new violation, the punishment for driving while under the influence of drugs. 6
*1283 Further, that result would be inconsistent with the design of the relevant Vehicle Code provisions to punish impaired drivers identically, whether they drive while under the influence of alcohol or drugs. As the Court of Appeal observed, Vehicle Code section 23152 does not make any distinction between a driver impaired by alcohol and a driver impaired by drugs. That section is part of a comprehensive statutory scheme encompassing both “driving-while-under-the-influence” treatment programs and mandatory incarceration. (See Veh. Code, § 23536 et seq.) An interpretation of section 1210.1, subdivision (b)(2) permitting a defendant convicted of misdemeanor driving while under the influence of drugs to receive probation and drug treatment under section 1210.1, subdivision (a), would afford drivers impaired by drugs more lenient treatment than that afforded drivers impaired by alcohol.
Although defendant suggests that such inconsistent treatment is justified because one who drives under the influence of alcohol has not ingested an illegal substance and has a much greater opportunity to participate in appropriate treatment programs, the fact remains that such an interpretation of the probation and diversion measures would work a modification of the statutes proscribing driving while under the influence, contrary to the representations made to the voters in the official ballot pamphlet.
*1284 3
We also briefly examine the Arizona statute (Ariz. Rev. Stat., § 13-901.01) that had its source in an initiative endorsed by the Arizona voters (Proposition 200), which became the model for California’s similar initiative measure. (See,
ante,
at p. 1280, fn. 3.) The purpose of the Arizona statute is to divert nonviolent drug users and possessors to drug treatment programs and reserve prison for drug dealers and violent offenders.
(State v. Tousignant
(2002)
Arizona Revised Statutes section 13-901.01 provides that a person convicted of “personal possession or use of a controlled substance or drug paraphernalia” is eligible to receive probation and treatment.

Defendant also observes that in
People
v.
Duncan
(1990)
The deferred entry of judgment statutes (§ 1000 et seq.) are in some ways analogous to Proposition 36.
(Varnell, supra,
As the court explained in
Duncan, supra,
Considering the foregoing points individually and collectively, it is evident to us that section 1210, subdivision (d)(2) may not fairly be construed to include the offense of misdemeanor driving while under the influence of drugs as an “activity similar” to the offenses described in section 1210, subdivision (d)(1). Accordingly, a conviction of misdemeanor driving while under the influence of drugs constitutes “a misdemeanor not related to the use of drugs” that, pursuant to section 1210.1, subdivision (b)(2), disqualifies a defendant from receiving the alternative disposition provided in section 1210.1, subdivision (a). Defendant, convicted of transporting a controlled substance and misdemeanor driving while under the influence of drugs in the same proceeding, is not entitled to, and the trial court did not err in denying, the probation and drug treatment provided under Proposition 36.
*1286 III
The judgment of the Court of Appeal is affirmed.
Kennard, J., Baxter, J., Werdegar, J., Chin, J., Brown, J., and Moreno, 1, concurred.
Notes
Proposition 36 is codified in Penal Code sections 1210, 1210.1, and 3063.1 and Health and Safety Code section 11999.4 et seq.
(People v. Superior Court
(Jefferson) (2002)
All further undesignated section references are to the Penal Code.
In Proposition 36, section 2, the findings and declarations provide in part: “[|] (a) Substance abuse treatment is a proven public safety and health measure. Nonviolent, drug-dependent criminal offenders who receive drug treatment are much less likely to abuse drugs and commit future crimes, and are likelier to live healthier, more stable and more productive lives. H] (b) Community safety and health are promoted, and taxpayer dollars are saved, when nonviolent persons convicted of drug possession or drug use are provided appropriate community-based treatment instead of incarceration. [1] (c) In 1996, Arizona voters . . . passed the Drug Medicalization, Prevention, and Control Act, which diverted nonviolent drug offenders into drug treatment and education services rather than incarceration .... [The Act] is ‘resulting in safer communities and more substance abusing probationers in recovery,’ has already saved state taxpayers millions of dollars, and is helping more than 75 percent of program participants to remain drug free.” (See Historical and Statutory Notes, 51 West’s Ann. Pen. Code (2004 supp.) foil. § 1210, p. 249.)
The Attorney General has requested that we take judicial notice of that portion of the California General Election Pamphlet prepared for the November 7, 2000 election pertaining to Proposition 36, including the ballot measure summary, analysis by the legislative analyst, arguments pro and con, and the text of the proposed law. We grant this request. (See
Varnell, supra,
30 CalAth 1132, 1144, fn. 7;
People
v.
Superior Court
(Turner) (2002)
The Attorney General’s ballot measure summary described the initiative as “[r]equir[ing] probation and drug treatment program, not incarceration, for conviction of possession, use, transportation for personal use or being under [the] influence of controlled substances and similar parole violations, not including sale or manufacture. []Q Permits additional probation conditions except incarceration.” (Ballot Pamp., Gen. Elec. (Nov. 7, 2000) Official Title and Summary of Prop. 36, p. 22.) The Legislative Analyst’s analysis of Proposition 36 informed the voters: “The measure defines a nonviolent drug possession offense as a felony or *1282 misdemeanor criminal charge for being under the influence of illegal drugs or for possessing, using, or transporting illegal drugs for personal use. The definition excludes cases involving possession for sale, producing, or manufacturing of illegal drugs. HI] • • • HI • • • This measure specifies that certain offenders would be excluded from its provisions and thus could be sentenced by a court to a state prison, county jail, or probation without drug treatment.. . . This measure also excludes offenders convicted in the same court proceeding of a misdemeanor unrelated to drug use or any felony other than a nonviolent drug possession offense. . . .” (Ballot Pamp., Gen. Elec. (Nov. 7, 2000) analysis of Prop. 36 by Legis. Analyst, p. 23.)
In her reply brief, defendant asserts that interpreting section 1210.1, subdivision (b)(2) not to exclude a defendant convicted of misdemeanor driving while under the influence of drugs from receiving probation and drug treatment pursuant to section 1210.1, subdivision (a), would not affect the Vehicle Code’s design of increasing the punishment for recidivist offenders. Defendant reasons that in the event a defendant completes drug treatment, section 1210.1, subdivision (d)(1) requires dismissal solely of “the charge upon which the Proposition 36 probation was granted,” and not the conviction of driving while under the influence of drugs. Thus, a subsequent conviction of driving while under the influence of drugs would be appropriately punished as a subsequent offense.
*1283 The relevant provisions do not support that view. As amended effective October 11, 2001, section 1210.1, subdivision (a) provides in part: “Notwithstanding any other provision of law, and except as provided in subdivision (b), any person convicted of a nonviolent drug possession offense shall receive probation,” conditioned upon “participation in and completion of an appropriate drug treatment program .... A court may not impose incarceration as an additional condition of probation. Probation shall be imposed by suspending the imposition of sentence.” As we have discussed {ante, at p. 1275), subdivision (b)(2) disqualifies a defendant who, in addition to a nonviolent drug possession offense, “has been convicted in the same proceeding of a misdemeanor not related to the use of drugs.” Subdivision (d)(1) provides in part that “[a]t any time after completion of drug treatment, a defendant may petition the sentencing court for dismissal of the charges. If the court finds that the defendant successfully completed drug treatment, ... the conviction on which the probation was based shall be set aside and the court shall dismiss the indictment, complaint, or information against the defendant. In addition . . . both the arrest and the conviction shall be deemed never to have occurred.” (Italics added.) Subdivision (e) provides for proceedings to continue or revoke the probation mandated by subdivision (a) when a defendant violates that probation by committing either a new nonviolent drug possession offense, or a new misdemeanor involving simple possession or use of drugs or paraphernalia, presence where drugs are used, failure to register, or similar activity (§ 1210, subd. (d)).
Considered as a whole, the provisions require probation for a conviction in the same proceeding of a nonviolent drug possession offense and a drug-related misdemeanor. The provisions also require that, following a defendant’s completion of drug treatment, the conviction itself, rather than a particular charge, will be dismissed, and, together with the arrest, will be deemed never to have occurred. Were we to conclude that a conviction of misdemeanor driving while under the influence of drugs does not preclude eligibility for probation and drug treatment under section 1210.1, subdivision (a), such a disposition would preclude the subsequent use of that misdemeanor to determine the appropriate punishment upon a new violation of the Vehicle Code.
