Drug charges in California: possession, sales and diversion, and what Prop. 36 changed

In California, simple possession of the drugs listed in Health and Safety Code §§ 11350 and 11377 is a misdemeanor with up to one year in county jail, while possession for sale is a felony-level offense (§§ 11351, 11378). A first possession case may qualify for pretrial diversion that ends in dismissal (Penal Code § 1000 and following). Since Proposition 36 took effect in December 2024, a person with two or more prior drug convictions who possesses a "hard drug" can be charged with a treatment-mandated felony (§ 11395).

Drug cases reach families in different ways: a few pills found in a car in Irvine, a vape cartridge at a party, or an accusation that someone was selling. The charge depends on what the substance was, how much there was, what the evidence says about sale, and the person's record. This page explains the main California possession and sales charges, the diversion and treatment routes, what Proposition 36 changed, and how cases move in Orange County. It sits under the firm's criminal defense and family law practice areas.

How a drug case moves in Orange County, step by step

1. The stop or search. Police find a substance on a person, in a car or in a home, and send it for testing. The legal identity of the substance decides which section applies.
2. Arrest or citation. A simple possession case may start with a citation; a sales allegation can mean booking and bail from the county schedule. Under § 11395, an arrest requires judicial review before release (§ 11395(f), Proposition 36 text). Release rules are on the page about how bail works in California.
3. The diversion review. For the possession offenses listed in Penal Code § 1000(a), the prosecutor must review the file for eligibility and state the grounds on the record, so the court can set a diversion hearing at the arraignment (§ 1000(b)).
4. Arraignment. Misdemeanors from Irvine, Newport Beach, Laguna Niguel, Mission Viejo and the rest of south county are heard at the Harbor Justice Center in Newport Beach; the Central Justice Center in Santa Ana lists every Orange County city for various felony hearings. The steps before that first hearing are explained on the page about arrest to arraignment in Orange County.
5. Diversion, treatment or litigation. The person may enter pretrial diversion, elect treatment under § 11395, be considered for an Orange County collaborative court such as Adult Drug Court, or contest the charge, for example by challenging the search or the lab result.
6. Resolution. Completed diversion ends in dismissal (§ 1000.3(d)); otherwise the case ends in dismissal, plea or trial.

Pretrial diversion under Penal Code § 1000

Diversion is an early question in a possession case. It applies to listed offenses, including §§ 11350, 11357, 11364, 11365 and 11377, and being under the influence, when four conditions are met: no conviction for other drug offenses in the five years before the charged offense; no crime of violence or threatened violence; no evidence of a contemporaneous drug violation beyond the listed offenses; and no felony conviction in the prior five years (§ 1000(a)).

To be granted diversion, the person pleads not guilty and waives the rights to a speedy trial, a speedy preliminary hearing and a jury trial, if applicable (§ 1000.1(a)(3), (b)). Diversion lasts from 12 to 18 months, and any bail posted is exonerated when it is granted (§ 1000.2(b), (c)). Statements made to the probation officer or treatment program during the process cannot be used later (§ 1000.1(c)). If the person completes the program, the charges are dismissed (§ 1000.3(d)) and the arrest is deemed never to have occurred, with exceptions for peace officer applications and access by criminal justice agencies (§ 1000.4(a), (c), (d)). Licensing agencies listed in Business and Professions Code § 144 may request diversion records (§ 1000.4(b)). If the person does not perform satisfactorily, or is convicted of a felony or a violent offense, diversion can be terminated and the case resumes (§ 1000.3).

What Proposition 36 changed for drug cases

Proposition 36, approved in November 2024, created a "treatment-focused court process for some drug possession crimes", in the words of the Legislative Analyst's Office. Its centerpiece is Health and Safety Code § 11395, the Treatment-Mandated Felony Act. It applies to a person who possesses a hard drug and has two or more prior convictions for listed drug offenses, including §§ 11350, 11351, 11377 and 11378, counting convictions from before the law took effect. "Hard drug" means a substance listed in §§ 11054 or 11055, including fentanyl, heroin, cocaine, cocaine base, methamphetamine and phencyclidine, and does not include cannabis, peyote, LSD, mescaline or psilocybin.

The person may elect treatment by pleading guilty or no contest and admitting the priors. An addiction evaluator ordered by the court assesses the person, the court approves a treatment plan and holds regular review hearings, and on successful completion the court dismisses the charge, with § 1000.4 applying as if the arrest had never occurred. If the person does not do well in treatment, the court can enter judgment and sentence them (§ 11395(d)(4)); otherwise, no one may be sentenced to jail or prison under this section unless the court finds them not eligible or suitable for treatment (§ 11395(b)(2)). Proposition 36 also requires courts to give a written advisory, known as Alexandra's Law, to people convicted of listed sale and possession-for-sale offenses involving a hard drug, warning that a resulting death could lead to a homicide charge (§ 11369). The same measure changed theft law, explained on the page about theft and fraud charges after Proposition 36.

What changes the answer?

• Possession or sale. Simple possession is up to one year in county jail (§§ 11350(a), 11377(a)); possession for sale carries felony-level terms under § 1170(h) (§§ 11351, 11378).
• Prior record. Two or more listed drug priors bring § 11395 into play; certain serious priors or sex offender registration allow § 1170(h) terms even for simple possession (§§ 11350(a), 11377(a)); and a drug conviction in the past five years can bar § 1000 diversion (§ 1000(a)(1)).
• Violence. A charge involving violence or threatened violence is not eligible for § 1000 diversion (§ 1000(a)(2)).
• Treatment history. A person convicted of a nonviolent drug possession offense must generally receive probation with drug treatment under § 1210.1(a), with exclusions such as certain prior serious or violent felonies (§ 1210.1(b)).
• Driving. Driving under the influence of a drug is a separate offense, explained on the page about how a California DUI case works.
• Firearms. A person addicted to a narcotic drug may not possess firearms (Pen. Code § 29800(a)(1)), and a prior drug conviction raises carrying charges (§ 25400(c)(5)); see the page on weapon and firearm charges.
• Citizenship. Before a guilty or no contest plea, the court must warn a noncitizen that a conviction may lead to deportation, exclusion or denial of naturalization (Pen. Code § 1016.5(a)). This matters especially because § 11395 treatment requires a guilty or no contest plea. This office does not give immigration advice.

A worked example

For example, imagine a 23-year-old in Mission Viejo, born in Tehran and now a permanent resident. This is a hypothetical, not a real case. During a traffic stop, an officer finds a small bag of pills in his jacket that he says a friend gave him for anxiety. The lab later reports a listed controlled substance. He has no criminal record.

The likely charge is simple possession under § 11350 or § 11377, a misdemeanor heard at the Harbor Justice Center. Because he has no drug conviction in the past five years, no felony and no violence, he appears to meet the § 1000(a) conditions, and the prosecutor must state for the record whether he is eligible. Diversion would require him to plead not guilty and waive time, attend a program approved under the county's rules for 12 to 18 months, and, if he completes it, the case would be dismissed and the arrest treated as if it never occurred, with the exceptions in § 1000.4. The defense would also examine the stop and the search before any decision.

Because he is a permanent resident, he should speak with a separate immigration attorney before choosing any path that involves a plea; this office does not give immigration advice. If his parents, who speak mostly Persian, want to understand the options, a Persian-speaking attorney can explain them, and a dismissal later can be paired with the record relief described on the page about clearing a record under Penal Code 1203.4.

Common mistakes in drug cases

• Explaining where the drugs came from at the roadside. Statements about sharing or selling can turn a possession case into a sales case.
• Pleading guilty before diversion is reviewed. Section 1000 diversion requires a not guilty plea, and the prosecutor's eligibility review comes first.
• Assuming Proposition 36 always means prison. Under § 11395, jail or prison is allowed only if the person is not eligible or suitable for treatment, or a ground in § 11395(d)(4) applies, such as failing treatment.
• Pleading without immigration advice. For noncitizens, speak with a separate immigration attorney before any plea, including a plea required to enter treatment under § 11395.
• Leaving diversion early. Unsatisfactory performance can end diversion and restart the case (§ 1000.3).
• Keeping firearms while addicted to a narcotic. That is itself a felony under § 29800(a)(1).

Frequently asked questions

Is drug possession a felony in California?

Simple possession under §§ 11350 and 11377 is punishable by up to one year in county jail, except for people with certain serious priors or a registration requirement. Since Proposition 36, possession of a hard drug by a person with two or more listed drug priors can be charged under § 11395, which allows a jail or § 1170(h) term only if the person is not eligible or suitable for treatment, or a ground in § 11395(d)(4) applies.

What is drug diversion under Penal Code 1000?

A pretrial program for listed possession offenses, lasting 12 to 18 months, for people who meet the § 1000(a) conditions. The person pleads not guilty and waives time, and on completion the charges are dismissed (§§ 1000.1 to 1000.3).

Will diversion show on my record?

After successful completion, the arrest is deemed never to have occurred and the court may seal the arrest records, but the arrest may still be disclosed for peace officer applications and remains accessible to criminal justice agencies (§ 1000.4).

What is a "hard drug" under Proposition 36?

A substance listed in Health and Safety Code § 11054 or § 11055, including fentanyl, heroin, cocaine, cocaine base, methamphetamine and phencyclidine. Cannabis, peyote, LSD, mescaline and psilocybin are excluded (§ 11395(e)).

Is there a drug court in Orange County?

The Orange County Superior Court runs Adult Drug Court, a voluntary program of at least 18 months in five phases for defendants who meet its eligibility criteria, as one of its collaborative courts.

Can a drug conviction affect my immigration status?

It can, which is why the court gives the § 1016.5 advisement before a plea. This office does not give immigration advice; speak with a separate immigration attorney first.
