Three different California ballot measures have been numbered Proposition 36, and each one changed criminal sentencing in a different direction. The 2000 version sends people convicted of nonviolent drug possession to treatment instead of jail. The 2012 version narrowed the Three Strikes Law so a life sentence generally requires a serious or violent third felony. The 2024 version, the most recent, raised penalties again for repeat drug and theft offenders. Which California Proposition 36 applies to a given case depends entirely on the charge and the year.
Proposition 36 (2024): Tougher Penalties for Repeat Drug and Theft Offenses
Passed in November 2024 as the Homelessness, Drug Addiction, and Theft Reduction Act, this measure rolled back parts of Proposition 47 and created new felony categories aimed at people with prior convictions.1Legislative Analyst’s Office. Proposition 36 Ballot Analysis
Treatment-Mandated Felonies for Drug Possession
Possessing fentanyl, heroin, cocaine, or methamphetamine can now be charged as a “treatment-mandated felony” rather than a misdemeanor when the defendant has two or more prior drug-related convictions. Complete the court-ordered treatment and the charges are dismissed. Refuse treatment or fail to finish and the sentence is up to three years in state prison.1Legislative Analyst’s Office. Proposition 36 Ballot Analysis
Repeat Theft and Aggregated Value
Under Proposition 47, stealing property worth $950 or less was generally a misdemeanor. The 2024 measure makes that same theft a felony punishable by up to three years when the defendant has two or more prior convictions for offenses like shoplifting, burglary, robbery, carjacking, grand theft, receiving stolen property, or identity theft. When three or more people commit a theft or property-damage offense together, the felony sentence can be extended by up to three additional years.1Legislative Analyst’s Office. Proposition 36 Ballot Analysis
Prosecutors also picked up a new charging tool. The value of property taken across multiple incidents can be combined into a single charge, so a string of small thefts that would each be misdemeanors can now be aggregated to hit the felony threshold. For serial shoplifting cases, this is often the provision that changes the outcome most.
Proposition 36 (2012): Three Strikes Reform
Before 2012, someone with two prior serious or violent felony convictions faced 25 years to life for any new felony, no matter how minor.2Legislative Analyst’s Office. 2011 Initiative Analysis – Three Strikes Reform Act of 2012 The Three Strikes Reform Act of 2012 changed that: for a life sentence, the third felony itself now generally has to be serious or violent. When the third strike is a non-serious, non-violent felony, the defendant is sentenced as a second-striker instead, meaning double the normal term for that crime rather than 25 to life.3California Legislative Information. California Penal Code PEN 667
Life sentences are still preserved in specific situations. If the current offense involved a firearm or deadly weapon, an intent to cause great bodily injury, a large-quantity controlled substance enhancement, or a sex crime requiring registration, the 25-to-life term still applies. The same is true when a prior strike was for particularly serious conduct such as homicide or attempted homicide, a sexually violent offense, child molestation of a victim under 14, solicitation to commit murder, or any serious or violent felony punishable by life or death in California.3California Legislative Information. California Penal Code PEN 667
Resentencing for People Already Serving Life
The 2012 measure also opened a resentencing petition for inmates already serving life terms whose third strike was not a serious or violent felony. The petition, filed in the original sentencing court, must list every felony that produced the life sentence and every prior strike that was alleged and proved.4California Legislative Information. California Penal Code PEN 1170.126
Eligibility tracks the same disqualifiers listed above. Meeting them is not enough on its own. The court makes a separate finding on whether releasing the petitioner would pose an unreasonable risk to public safety, weighing the person’s criminal history, prison disciplinary record, rehabilitation efforts, and any other evidence the court finds relevant. If the petition is granted, the life sentence is vacated and a second-strike sentence takes its place. People serving enhanced second-strike terms are not eligible for this process.4California Legislative Information. California Penal Code PEN 1170.126
Proposition 36 (2000): Drug Treatment Instead of Jail
The Substance Abuse and Crime Prevention Act of 2000 requires probation with mandatory treatment, not incarceration, for anyone convicted of personally using, possessing for personal use, or transporting drugs for personal use. Under Penal Code 1210.1, the court cannot tack jail time onto that probation as an extra condition.5California Legislative Information. California Penal Code PEN 1210.1
Not everyone qualifies. The law excludes anyone with a serious or violent felony conviction in the past five years, unless they stayed out of prison custody and free of new felony convictions during that entire period. It also excludes people convicted of a non-drug misdemeanor or any additional felony in the same proceeding. A co-occurring psychiatric or developmental disorder, by itself, cannot be used to deny eligibility.5California Legislative Information. California Penal Code PEN 1210.1
Dismissal After Successful Treatment
The main benefit comes at the end. When the court finds that the defendant finished treatment and substantially complied with probation, including staying drug-free after the program, the conviction is set aside and the charges are dismissed. The arrest and conviction are then treated as though they never happened, and the person can generally answer “no” to prior criminal history questions on applications.5California Legislative Information. California Penal Code PEN 1210.1
The clean slate is not absolute. A dismissed conviction still bars firearm ownership, and law enforcement can still see the record. Disclosure is also required on applications for public office, peace officer positions, state or local licensing, California State Lottery contracts, and jury service questionnaires.5California Legislative Information. California Penal Code PEN 1210.1
Immigration Risk for Non-Citizens
None of these state measures shield a non-citizen from federal immigration consequences. Under federal law, any non-citizen convicted of a controlled substance offense at the state or federal level is deportable, with a narrow exception for a single offense of possessing 30 grams or less of marijuana for personal use.6Office of the Law Revision Counsel. 8 USC 1227 – Deportable Aliens A lawful permanent resident can lose a green card, a visa holder can be blocked from future applications, and a pending citizenship application will almost certainly be denied. A waiver for drug-related inadmissibility is generally unavailable, though a certified remission of a substance use disorder can sometimes overcome the health-related inadmissibility ground through a medical re-examination.7U.S. Citizenship and Immigration Services. Waiver of Drug Abuse and Addiction Anyone who is not a U.S. citizen should talk to an immigration attorney before accepting any plea deal on a drug charge, including one that sends them to treatment rather than jail.
