Prop 36 Drug Possession Felony: Treatment Option

October 16, 2026

Quick Answer 

A Prop 36 drug possession felony is formally called a treatment-mandated felony and comes from Health and Safety Code 11395. It applies when a person is charged with possessing a “hard drug” such as fentanyl or heroin after two or more earlier drug convictions. The charge is a wobbler, which means it can be punished as a misdemeanor or as a felony. A person charged this way may elect treatment instead of jail or prison by pleading guilty or no contest and agreeing to complete a court-approved program. A person who completes treatment can have the charge dismissed. 

Summary 

• The charge applies only to possession of listed hard drugs by a person with two or more qualifying prior drug convictions. 

• The person may elect treatment in place of jail or prison by entering a plea and agreeing to a court-approved program. 

• Successful completion leads to a dismissal that California law says does not count as a conviction. 

• Immigration law may treat the plea differently so noncitizens need advice before any plea. 

• The theft rules in Proposition 36 are separate and work differently. 

Introduction 

Proposition 36 took effect on December 18, 2024. On the drug side it created a new offense for repeat possession of hard drugs along with a treatment path that lets the person avoid incarceration. Before this change possession of a controlled substance for personal use was often a misdemeanor even for a person with several earlier drug cases. 

This guide explains what the treatment-mandated felony is and which drugs and prior convictions trigger it. It also walks through how the treatment option works and what happens when treatment succeeds or ends early. It covers the drug possession provisions only. The theft provisions of Proposition 36 follow different rules and are covered in DefendCA’s guide to Prop 36 felony theft in California. 

What Is a Prop 36 Drug Possession Felony? 

A Prop 36 drug possession felony is a charge under Health and Safety Code 11395 against a person who possesses a hard drug without a valid prescription and who has two or more qualifying prior drug convictions. The statute calls itself the Treatment-Mandated Felony Act. The offense is a wobbler so it can be punished as a misdemeanor or as a felony. 

Two things have to be present: 

• The person possesses a hard drug without a valid prescription. 

• The person has two or more prior convictions for offenses listed in the statute and the prosecution alleges and proves them. 

The new offense must have happened on or after December 18, 2024. The Immigrant Legal Resource Center explains that the earlier convictions can be from any time. 

Section 11395 does not cover possession for sale or the sale and transportation of drugs. Those charges fall under other statutes and carry different penalties. 

Which Drugs Count as Hard Drugs Under Prop 36? 

A hard drug is a controlled substance listed in Health and Safety Code 11054 or 11055 with certain exceptions. The definition names fentanyl, heroin, cocaine, cocaine base, methamphetamine and phencyclidine (PCP) along with their analogs. 

Methamphetamine is the exception inside section 11055(d). It is covered even though most other substances in that subdivision are not. The definition works by reference to the drug schedules so the exact substance involved matters and is worth confirming against the lab report and the statute. 

Which Prior Convictions Trigger the Charge? 

Section 11395 requires two or more prior convictions for specific drug offenses. The priors can be misdemeanors or felonies and the statute sets no time limit. Convictions from before December 18, 2024 count. 

The listed offenses are violations of Health and Safety Code sections 11350, 11351, 11351.5, 11352, 11353, 11353.5, 11353.7, 11370.1, 11377, 11378, 11378.5, 11379, 11379.5, 11379.6, 11380 and 11395 itself. In plain terms they cover drug possession, sale, possession for sale and possession while armed. 

Several details affect whether a prior counts: 

• Pleading and proof. The priors must be alleged in the charging document and then admitted in open court or found true by the judge or jury. 

• Offenses that do not count. The ILRC advisory says being under the influence and possessing paraphernalia are not on the list. 

• Diversion and treatment outcomes. The ILRC says a pretrial diversion that ends without a conviction and a completed treatment program under section 11395 are not convictions under state law and cannot serve as priors. 

• Dismissed convictions. The ILRC also says a conviction later dismissed under Penal Code 1203.4 can still count. 

What Penalties Can Apply to a Prop 36 Drug Possession Charge? 

The offense is a wobbler. A first conviction is punishable by county jail either as a misdemeanor (up to one year) or as a felony under Penal Code 1170(h) which covers felony sentences served in county jail. Senate Public Safety Committee staff describe the felony county jail term as up to three years for a first offense. A second or later conviction can result in county jail or state prison. 

The treatment option changes how those penalties work in practice. A court generally cannot sentence the person to jail or prison under section 11395 unless it first finds the person ineligible or unsuitable for treatment or finds one of the grounds for ending treatment described below. The sentence a court actually imposes depends on the facts and on the person’s record. 

Two other features matter. Section 11395 applies “notwithstanding any other law” so it can reach conduct that would otherwise be a misdemeanor under Health and Safety Code 11350 or 11377 or be eligible for Penal Code 1000 diversion according to the Attorney General’s information bulletin. After an arrest the statute also requires a court to review the person’s risk to public safety and likelihood of returning to court before release.

How Does the Treatment Option Work? 

A person charged under section 11395 may elect treatment instead of jail or prison. The process is a form of deferred entry of judgment which means the case is paused after a plea while the person completes treatment. It is not diversion because the plea comes first. 

The steps in the statute run in this order: 

1. The election. The person pleads guilty or no contest and admits the alleged priors. The person also waives time for sentencing and judgment and agrees to complete a treatment program that a drug addiction expert develops and the court approves. Under California law the plea is not a conviction unless the court later enters judgment because treatment ends early. 
2. Evaluation. The court may order a substance abuse and mental health evaluation at the request or with the consent of the defendant or counsel. With the person’s consent the court may also check eligibility for benefits such as Medi-Cal. 
3. The program. Treatment can include drug treatment and mental health treatment along with job training and other court-approved conditions. The court holds regular progress hearings. 
4. Cost and access. The court refers the person to no-cost programs that it and the parties consider credible and effective. A person may also pay for a court-approved program. 
5. Custody credit. Time in residential treatment earns actual-time credit under Penal Code 2900.5. Other programs and counseling earn no credit. 

Senate Public Safety staff note that the statute sets no length or standard conditions for treatment and does not say what happens if no program is available. In practice the details depend on the court and the program. Ask the attorney and the court which programs are approved for the case. 

What Happens When You Complete Treatment? 

After successful completion the charge is dismissed. The court needs a positive treatment recommendation and a motion to dismiss which the defendant, the prosecutor, the court or probation can bring. Penal Code 1000.4 then applies and the arrest is treated as though it never occurred. 

The statute says the dismissal does not count as a conviction for any purpose including as a prior under section 11395 itself. That is the state-law result. How a dismissal appears on a background check or a licensing application is a separate question and a lawyer can address it for a specific situation. 

What Happens If Treatment Ends Early or Fails? 

Treatment can be terminated and the case can move to judgment and sentencing. The prosecutor or probation can ask the court to end treatment and the court can also act on its own. The grounds in the statute are: 

• Unsatisfactory performance in the program 

• Not benefiting from treatment or not being amenable to it 

• Refusing treatment 

• A conviction for a crime committed after treatment began 

The court holds a notice and hearing before it decides. If it finds one or more grounds true it enters judgment and sentences the person under section 11395. 

The court may instead send the person back to treatment if that serves the interest of justice and the person is currently amenable and agrees to participate and complete a program. Re-referral is not available when the person has been found to have committed a new crime since treatment began. Nothing here is guaranteed and every case turns on its own facts. 

Does Prop 36 Treatment Affect Immigration Status? 

It can. California law says a completed section 11395 program is not a conviction. Federal immigration law uses its own definition under 8 U.S.C. 1101(a)(48)(A) which looks at whether the person entered a plea and whether a judge imposed some form of punishment or restraint. The ILRC advisory concludes that the plea and the treatment requirement can make the case a conviction for immigration purposes even if the person completes treatment and the charge is dismissed under state law. 

The ILRC also notes that pretrial diversion without a plea is treated differently from deferred entry of judgment. Any noncitizen facing a drug charge should speak with a criminal defense lawyer who understands immigration consequences before entering a plea or choosing treatment. 

What Else Did Prop 36 Change for Drug Cases? 

Several other changes affect drug sales and fentanyl cases. They are separate from the treatment option: 

• Written warning. Under Health and Safety Code 11369 a court must give a written warning to a person convicted of certain hard drug sale offenses. The warning says that illegally making or selling drugs can be deadly and that a resulting death could lead to a homicide charge. 

• Fentanyl weight enhancements. Health and Safety Code 11370.4 sets added prison terms based on the amount of fentanyl involved in certain sale and transportation offenses. 

• Possession while armed. Health and Safety Code 11370.1 now covers substances containing fentanyl. 

What Should You Do If You Face a Prop 36 Drug Charge? 

Read the charging document and identify which prior convictions the prosecution relies on and which substance is alleged. Speak with a California criminal defense attorney before entering a plea because the plea is the first step of the treatment option and it can carry consequences beyond the case itself. 

These steps are general information and not advice for a specific case: 

1. Check whether the complaint cites Health and Safety Code 11395 and lists the priors. 
2. Gather records from earlier cases if you have them. Each alleged prior has to be a listed offense and has to be proved. 
3. Do not discuss the case with anyone other than your lawyer. 
4. Attend every court date. 
5. Ask about immigration and licensing consequences before any plea. 
6. If treatment is offered ask what program the court would approve and what the court expects at each progress hearing.

Conclusion 

Proposition 36 created a felony option for repeat hard drug possession and paired it with a treatment path that lets a person avoid jail or prison. What happens in a particular case depends on the substance and the alleged priors along with the court’s findings about treatment.
