California Psychedelics Laws: Penalties, Diversion, and Reform

California psychedelics laws still classify psilocybin, LSD, DMT, MDMA, mescaline, and similar substances as Schedule I controlled substances, which means possessing them without authorization is illegal. What has changed is the severity: since Proposition 47 passed in 2014, simple possession is a misdemeanor carrying up to a year in county jail and a maximum $70 fine, and most first-time defendants qualify for a diversion program that ends with the charges dismissed. Three cities have deprioritized enforcement, a statewide decriminalization bill was vetoed in 2023, and FDA decisions on psilocybin-based therapy are expected in late 2026 or early 2027.

Which Substances Are Covered

California’s Health and Safety Code Section 11054 lists hallucinogens as Schedule I controlled substances. Subdivision (d) covers psilocybin, psilocyn, DMT, LSD, mescaline, peyote, ibogaine, and dozens of synthetic variants.1California Legislative Information. California Code Health and Safety Code HSC 11054 MDMA is also Schedule I, in a different subdivision of the code. State classification mirrors federal law: under 21 U.S.C. § 812, Schedule I substances are defined as having a high potential for abuse, no accepted medical use, and a lack of accepted safety even under medical supervision.2Office of the Law Revision Counsel. 21 U.S. Code 812 – Schedules of Controlled Substances Possession carries both state and federal exposure in theory, though federal prosecution of simple possession is rare.

Ketamine sits outside this group. It’s a Schedule III substance, which means licensed physicians can prescribe it for off-label uses including treatment-resistant depression and chronic pain. Ketamine-assisted therapy clinics operate legally throughout California and are currently the only widely available psychedelic-adjacent treatment under state law.

Penalties for Simple Possession

Simple possession of psychedelics in California is a misdemeanor, not a felony. Proposition 47, approved by voters in 2014, reclassified possession offenses under Health and Safety Code Section 11377 from felonies and wobblers down to straight misdemeanors.3California Courts. Proposition 47 Frequently Asked Questions The change applies to psilocybin, LSD, MDMA, and the other substances listed under Section 11377.

The maximum penalty for a first offense is up to one year in county jail. The statutory fine cap is $70, written directly into the statute, and the court must consider the defendant’s ability to pay.4California Legislative Information. California Health and Safety Code 11377 Many first-time cases resolve with probation rather than jail time, particularly when diversion is on the table.

One narrow exception moves possession out of the misdemeanor box. People with prior convictions for certain serious violent felonies or sex offenses requiring registration can still be sentenced under Penal Code 1170(h), which allows state prison time.4California Legislative Information. California Health and Safety Code 11377 For everyone else, simple possession stays misdemeanor-level.

Proposition 36 and Repeat Offenders

Voters approved Proposition 36 in November 2024, partially rolling back Proposition 47 for certain repeat drug offenders. Prosecutors can now charge a “treatment-mandated felony” instead of a misdemeanor when someone possesses drugs and has two or more prior drug convictions. The measure specifically targets fentanyl, heroin, cocaine, and methamphetamine.5Legislative Analyst’s Office. Proposition 36 Ballot Analysis Defendants who complete court-ordered treatment have their charges dismissed; those who refuse or drop out face up to three years in state prison. Whether this provision will be used routinely against psychedelics possession is still unsettled, but the mechanism exists.

Possession for Sale and Distribution

Penalties jump sharply once conduct crosses from personal use to commercial activity. Possessing psychedelics for sale is a felony under Health and Safety Code Section 11378, punishable by a state prison sentence of 16 months, two years, or three years under Penal Code 1170(h).6California Legislative Information. California Health and Safety Code 11378

Actually selling, transporting, or giving away psychedelics carries two, three, or four years in state prison under Health and Safety Code Section 11379. Transportation across noncontiguous county lines (counties that don’t share a border) carries three, six, or nine years.7California Legislative Information. California Health and Safety Code 11379 The statute defines “transports” as transporting for sale, so moving personal-use quantities between locations does not automatically trigger these penalties.

Prosecutors use quantity, packaging materials, scales, large amounts of cash, and communications evidence to argue intent to sell. The gap between a misdemeanor with a $70 fine and a multi-year prison sentence often comes down to those facts.

Drug Diversion Under Penal Code 1000

Diversion is the most important thing to understand for anyone facing a possession charge. California Penal Code Section 1000 lets eligible defendants charged with simple possession under HSC 11377 complete a drug education or treatment program instead of being convicted.8California Legislative Information. California Penal Code 1000

To qualify, the defendant must meet all of the following:

  • No conviction for a controlled substance offense in the five years before the current charge.
  • No violence or threat of violence in the current offense.
  • No evidence of another narcotics violation at the same time.
  • No felony conviction of any kind in the five years before the current charge.

The prosecutor reviews these criteria and files a declaration with the court on eligibility. Accepted defendants enter a certified drug treatment or education program. Successful completion means the charges are dismissed, with no conviction on the record. Participants may be required to submit to drug testing during the program, and those test results cannot be used as the basis for a new criminal prosecution.8California Legislative Information. California Penal Code 1000

Diversion is the single biggest reason most first-time psychedelics cases in California don’t end in conviction. Defense attorneys usually push for diversion eligibility as the first priority.

Collateral Consequences Beyond the Criminal Case

Even a misdemeanor drug conviction, and in some cases just an arrest, can create problems that outlast the court case.

On housing, federal guidelines give public housing authorities broad discretion to deny admission or terminate assistance based on drug-related criminal activity. A mandatory denial applies to anyone evicted from federally assisted housing within the prior three years for drug-related activity, anyone currently using illegal drugs, or anyone convicted of manufacturing methamphetamine in federally assisted housing. Housing authorities can also screen applicants for any criminal history that might affect the safety or peaceful enjoyment of the property.

On education, federal student financial aid is no longer automatically denied based on a drug conviction; that rule changed starting with the 2021–2022 school year. Some state grants, private scholarships, and individual colleges keep their own policies that may disqualify applicants with drug convictions, and private student loan lenders may consider criminal history.

On employment, professional licensing boards in healthcare, law, education, and other fields routinely ask about convictions. A misdemeanor drug possession conviction can complicate or delay licensure. This is where successful diversion becomes especially valuable, because a dismissed charge carries far less weight than a conviction.

Cities That Have Deprioritized Enforcement

Three California cities have passed resolutions making enforcement of psychedelics laws among the lowest priorities for local police. State law has not changed in those places; local arrests simply become much less likely.

Oakland acted first. In June 2019, the city council unanimously adopted a resolution directing law enforcement to treat the investigation and arrest of adults involved with entheogenic plants on the federal Schedule I list as among the lowest enforcement priorities.9City of Oakland. File 18-1790 – Decriminalizing Entheogenic Plants The resolution covers plant and fungi-derived psychedelics but not synthetics like LSD or MDMA.

Santa Cruz followed in January 2020 with a unanimous council vote adopting a similar resolution covering a broad range of psychedelics.10Senator Scott Wiener. In Historic First, Legislation to Decriminalize Possession and Personal Use of Psychedelics Passes Senate Public Safety Committee San Francisco adopted Resolution 379-22 in September 2022, urging law enforcement to make investigation and arrest of adults for planting, cultivating, purchasing, transporting, distributing, or possessing entheogenic plants among the city’s lowest priorities, and urging that city resources not be used for enforcement arising from these activities.11San Francisco Board of Supervisors. Resolution 379-22 – Supporting Entheogenic Plant Practices

These resolutions do not change state law and do not legalize sales. State or federal authorities can still bring charges. If you possess psychedelics for personal use in one of these cities, you are much less likely to be arrested by local police, but you are not legally protected.

Religious and Medical Exceptions

Federal law carves out a narrow religious exemption for peyote use by members of the Native American Church. Under 42 U.S.C. § 1996a, use, possession, and transportation of peyote by Native Americans for traditional ceremonial purposes is protected, and no state or federal agency may prohibit it.12Office of the Law Revision Counsel. 42 U.S. Code 1996a – Traditional Indian Religious Use of Peyote The protection is subject to the balancing test under the Religious Freedom Restoration Act and allows restrictions in safety-sensitive jobs like law enforcement or public transportation.

California does not have a state-level religious exemption for other psychedelics. Groups that use ayahuasca (which contains DMT) or psilocybin mushrooms as spiritual sacraments have raised RFRA defenses, but no California-specific statute shields them from prosecution, and any defense would need to be built case by case in federal court.

On the medical side, no psychedelic substance other than ketamine is currently available by prescription in California. For patients interested in psychedelic-assisted mental health treatment, ketamine remains the only lawful option under current state law.

Where California Reform Stands Now

The most prominent push for statewide reform was Senate Bill 58 from Senator Scott Wiener, which would have decriminalized personal possession and use of specified quantities of mescaline, DMT, psilocybin, and psilocyn for adults 21 and older. It passed both chambers before Governor Newsom vetoed it on October 7, 2023. Newsom did not reject the concept outright. His veto message said California should “immediately begin work to set up regulated treatment guidelines” covering dosing, therapeutic protocols, protections against exploitation during guided sessions, and medical screening for underlying psychotic conditions. His objection was that the bill decriminalized possession before those guidelines existed.13Governor of California. Senate Bill 58 Veto Message

Wiener followed in 2024 with SB 1012, which took the therapeutic-framework-first approach Newsom had asked for. It would have created a Board of Regulated Psychedelic Facilitators, set licensing requirements for therapists conducting psychedelic-assisted sessions, and established an expert oversight committee. SB 1012 was held in committee in May 2024 and never reached the governor.

Since those two failures, the legislative strategy has shifted toward research access. AB 1103, signed into law in October 2025, streamlines approval for psychedelic research studies by letting a smaller cohort of the state’s Research Advisory Panel approve qualifying applications without a full panel vote. AB 2489 would let the panel submit FDA applications for clinical trials using certain Schedule I and II substances, including psilocybin, specifically for veterans. SB 751 would establish a Veterans and First Responders Research Pilot Program focused on psilocybin services in up to five counties, and may be reconsidered in 2026.

What the FDA Could Change

Federal developments may matter more than state ones in the near term. The FDA rejected MDMA-assisted therapy for PTSD in August 2024, issuing a complete response letter that pointed to problems with adverse event reporting, questions about whether the treatment effect lasted beyond the 18-week study period, and selection bias concerns because roughly 40% of participants had prior MDMA experience. The agency said the most efficient path forward would be a new clinical trial.14U.S. Food and Drug Administration. Complete Response Letter NDA 215455

Psilocybin is further along. Multiple synthetic psilocybin formulations have received FDA breakthrough therapy designation, and at least three groups are running Phase 3 clinical trials, with results expected throughout 2026 and into early 2027. If any receives FDA approval, prescribed psilocybin therapy would become legal in California the same way ketamine is now, without any change in state law. Federal approval would not decriminalize personal possession or recreational use, but it would open a clinical pathway for Californians seeking psychedelic-assisted treatment.
