Psychedelics are illegal in California. Under California psychedelics laws, substances like psilocybin, LSD, DMT, mescaline, and MDMA are classified as Schedule I controlled substances, and possessing them without authorization is a misdemeanor punishable by up to a year in county jail. That said, a first offense usually carries a maximum fine of just $70, and most eligible defendants can complete a diversion program that ends with the charges dismissed. The bigger risks come from selling or transporting, which remain felonies, and from collateral consequences that can outlast the case itself.
How the State Classifies These Substances
California Health and Safety Code Section 11054 lists psilocybin, psilocyn, DMT, LSD, mescaline, peyote, ibogaine, and dozens of synthetic variants as Schedule I hallucinogens.1California Legislative Information. California Code Health and Safety Code HSC 11054 MDMA is also Schedule I, listed in a different subdivision. State law mirrors federal law here: 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 Californians face both state and federal exposure, though federal prosecution of simple possession is rare.
Ketamine is the one meaningful exception. It’s classified as Schedule III, which means licensed physicians can prescribe it for off-label uses like depression and chronic pain. Ketamine-assisted therapy clinics operate legally throughout the state and are, for now, the only widely available psychedelic-adjacent treatment under California law.
Penalties for Personal Possession
Simple possession of psychedelics in California is a misdemeanor, not a felony. California voters passed Proposition 47 in 2014, which reclassified possession offenses under Health and Safety Code Section 11377 from felonies (or wobblers) to straight misdemeanors.3California Courts. Proposition 47 Frequently Asked Questions That change covers psilocybin, LSD, MDMA, and other substances listed under Section 11377.
The maximum penalty for a first offense is up to one year in county jail. The maximum fine 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 In practice, first-time cases often result in probation rather than jail, especially when diversion is available.
There is one narrow exception. People with prior convictions for certain serious violent felonies or sex offenses requiring registration can still be sentenced to state prison time under Penal Code 1170(h).4California Legislative Information. California Health and Safety Code 11377 For everyone else, simple possession stays at the misdemeanor level.
Proposition 36 and Repeat Offenders
Voters approved Proposition 36 in November 2024, partially rolling back Proposition 47 for certain repeat drug offenders. Under Proposition 36, prosecutors can 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 prosecutors will routinely apply this to psychedelics cases remains to be seen, but the mechanism exists.
Penalties for Selling or Transporting
Penalties climb sharply once possession crosses from personal use to commercial activity. Possessing psychedelics for sale is a felony under Health and Safety Code Section 11378, punishable by 16 months, two years, or three years under Penal Code 1170(h).6California Legislative Information. California Health and Safety Code 11378
Selling, transporting, or giving away psychedelics carries a state prison sentence of two, three, or four years under Health and Safety Code Section 11379. If the transportation crosses noncontiguous county lines (counties that don’t share a border), the range increases to 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 from one place to another does not automatically trigger these penalties.
Prosecutors use quantity, packaging materials, scales, large amounts of cash, and communications evidence to distinguish personal use from intent to sell. The difference between a $70 misdemeanor fine and a multi-year prison sentence can come down to those facts.
Diversion Under Penal Code 1000
For most people caught with psychedelics, diversion is the realistic outcome. 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, all of the following must be true:
- No conviction for a controlled substance offense within the five years before the current charge.
- The current offense did not involve violence or the threat of violence.
- No evidence of another narcotics violation at the same time.
- No felony conviction of any kind within the five years before the current charge.
The prosecutor reviews these criteria and files a declaration on eligibility. If accepted, the defendant enters a certified drug treatment or education program. Successful completion results in dismissal, with no conviction on the record. Participants may be required to submit to drug testing during the program, but those test results cannot be used to build a new criminal case.8California Legislative Information. California Penal Code 1000 Defense attorneys who handle these cases routinely treat diversion eligibility as the first and most important goal.
Consequences Beyond the Criminal Case
Even a misdemeanor conviction, or in some cases just an arrest, can create problems that outlast the case itself. These collateral consequences are easy to overlook during a plea negotiation, which is exactly when they matter most.
Housing is one pressure point. 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. Beyond those mandatory bars, housing authorities can screen for any criminal history that might affect the safety or peaceful enjoyment of the property.
Education is less of a problem than it used to be. Federal student aid is no longer automatically denied based on a drug conviction, a change that took effect starting with the 2021–2022 school year. Some state grants, private scholarships, individual colleges, and private student loan lenders still maintain their own policies that may weigh a drug conviction against an applicant.
Employment and licensing may be the most durable issue. Licensing boards in healthcare, law, education, and other regulated fields routinely ask about criminal convictions, and a possession conviction, even a misdemeanor, can complicate or delay licensure. This is where diversion pays off: a dismissed charge carries far less weight than a conviction.
Cities That Deprioritize Enforcement
Three California cities have passed resolutions making enforcement of psychedelics laws a low law enforcement priority. These create pockets where personal use is unlikely to draw an arrest, but they do not change the underlying state law.
Oakland went first. In June 2019, the city council unanimously adopted a resolution directing local law enforcement to treat the investigation and arrest of adults involved with entheogenic plants on the federal Schedule I list as among the lowest priorities.9City of Oakland. File 18-1790 – Decriminalizing Entheogenic Plants The resolution covers plant-based and fungi-derived psychedelics but not synthetic substances like LSD or MDMA.
Santa Cruz followed in January 2020 with a unanimous city 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.11San Francisco Board of Supervisors. Resolution 379-22 – Supporting Entheogenic Plant Practices
These resolutions direct local police and prosecutors to deprioritize enforcement. They do not legalize anything, and they do not stop state or federal authorities from bringing charges. They also do not authorize sales. If you possess psychedelics for personal use in one of these cities, you are far 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, the 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
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 attempted to claim protection under the federal Religious Freedom Restoration Act, but no California statute shields them from prosecution. Any such defense would have to be raised case by case in federal court.
On the medical side, no psychedelic other than ketamine is available through legal prescription in California. Ketamine’s Schedule III status lets licensed physicians prescribe it off-label for conditions like treatment-resistant depression, and clinics offering ketamine infusions and ketamine-assisted therapy operate legally across the state. For patients interested in psychedelic-assisted mental health treatment, ketamine is the only lawful option right now.
Where Reform Stands
The most prominent statewide push was Senate Bill 58, introduced by Senator Scott Wiener. It would have decriminalized personal possession and use of specified quantities of mescaline, DMT, psilocybin, and psilocyn for adults 21 and older. The bill passed both chambers before landing on Governor Newsom’s desk.
Newsom vetoed SB 58 on October 7, 2023. He 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 responded with SB 1012 in 2024, a therapeutic-framework-first bill that would have created a Board of Regulated Psychedelic Facilitators, established licensing requirements for therapists conducting psychedelic-assisted sessions, and set up an expert committee to develop safety regulations. It was held in committee in May 2024 and never reached the governor.
Since then, California bills have shifted toward research access rather than decriminalization. AB 1103, signed into law by Newsom in October 2025, streamlines approval for psychedelic-focused research studies. AB 2489 would let the state’s Research Advisory 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.
The federal picture may matter more in the near term. The FDA rejected MDMA-assisted therapy for PTSD in August 2024, citing concerns about how adverse events were reported in clinical trials, a failure to show durability of effect past the 18-week study period, and questions about selection bias.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 trials: Compass Pathways’ COMP360 for treatment-resistant depression, with results expected throughout 2026 and possible approval by the end of that year; HLP003 as an add-on treatment for major depressive disorder, with Phase 3 results expected in late 2026; and Usona Institute’s synthetic psilocybin as a single-dose treatment for major depressive disorder, with Phase 3 results expected in late 2026 or early 2027.
If any of these receives FDA approval, it would open a legal pathway for prescribed psilocybin therapy in California without any change in state law, the same way ketamine is available now. Federal approval would not decriminalize personal or recreational use, but it would let qualified providers administer psilocybin in a clinical setting.
