Magic mushrooms have gained attention in recent years for their potential therapeutic benefits. Clinical trials show promise for treating depression, PTSD, and anxiety. Cities across the country are reconsidering their approach to psilocybin, the active compound in these fungi.
But are mushrooms legal in California in 2025?
Magic mushrooms in California remain illegal under state law.
Despite growing interest in psychedelic therapy and several legislative attempts to change the law, possession, cultivation, and sale of psilocybin mushrooms are still criminal offenses under both state and federal law.
What California Law Says About Psilocybin
California classifies psilocybin and psilocyn as Schedule I controlled substances under the Health and Safety Code. This puts magic mushrooms in the same category as heroin and LSD.
You can face criminal charges for:
- Possessing magic mushrooms
- Growing psilocybin-containing fungi
- Selling or distributing mushrooms
- Transporting psilocybin across state or county lines
Penalties You Could Face
Simple possession typically results in misdemeanor charges:
- Up to one year in county jail
- Fines up to $1,000
Cultivation or sales charges are more serious. These can be charged as felonies, potentially leading to state prison time.
The Confusion Around Decriminalization
Several California cities have passed measures that make people think magic mushrooms are legal:
- Oakland
- San Francisco
- Santa Cruz
- Berkeley
- Arcata
What These Measures Actually Do
They make enforcement of psilocybin laws a low priority for local police. Officers in these cities are directed to deprioritize arrests and citations for personal possession and use.
What They Don’t Do
Deprioritization is not legalization. You can still be arrested and charged under state law, even in these cities. Travel outside city limits with mushrooms? You’re subject to enforcement by county sheriffs and state officers who aren’t bound by these local policies.
Recent Legislative Attempts
California lawmakers have tried multiple times to change the state’s approach to psychedelics.
Senate Bill 58: The Closest California Came
State Senator Scott Wiener introduced SB 58 in 2023. The bill would have:
- Decriminalized possession and personal use of psilocybin, psilocyn, DMT, and mescaline
- Applied to adults 21 and older
- Taken effect January 1, 2025
The bill passed both chambers with bipartisan support.
Why It Failed
Governor Gavin Newsom vetoed the bill in October 2023.
His reasoning? California needed proper therapeutic guidelines and safety protocols first:
- Dosing information
- Therapeutic guidelines
- Protections against exploitation during guided treatments
- Medical screening for underlying psychoses
He acknowledged California’s role in leading drug policy reform. But he wasn’t ready to implement decriminalization without these safeguards in place.
What About Therapeutic Use?
Some people assume psilocybin is available for therapy in California. Two common misconceptions drive this:
Misconception #1: Research institutions like UCLA and UC San Francisco are conducting clinical trials, so therapy must be available.
The reality: Clinical trials operate under strict federal research protocols. They’re not accessible to the general public.
Misconception #2: Oregon has legalized psilocybin therapy, so California must have something similar.
The reality: California has no legal framework for therapeutic psilocybin services.
As of 2025, there are no licensed clinics or centers in California where you can legally use psilocybin for therapy. Anyone advertising such services is operating outside the law.
Federal Law Still Applies
Even if California legalized psilocybin at the state level, federal law would still classify it as a Schedule I controlled substance.
Federal agencies can:
- Enforce drug laws independently
- Work with state and local law enforcement
- Prosecute cases regardless of state law
Think of It Like Marijuana
Cannabis is legal under California law, but remains federally illegal. This creates ongoing tensions and legal uncertainties.
For psilocybin—which lacks the commercial infrastructure and widespread acceptance of cannabis—federal prohibition creates even more risk.
Interstate transport always falls under federal jurisdiction. Cross state lines with mushrooms and you’re breaking federal law.
Real-World Consequences of Possession
If you’re caught with magic mushrooms in California, the consequences depend on several factors: the amount in your possession, whether there’s evidence of intent to sell, your criminal history, and where you were arrested.
First-time possession of a small amount might result in:
- Misdemeanor charges
- Up to one year in county jail
- Fines up to $1,000
- Informal probation
- Drug education programs
More serious charges—cultivation, sales, or possession of large quantities—can lead to felony convictions. These carry longer sentences and create lasting problems with employment, housing, and professional licensing.
What Might Change
The law will likely continue evolving as research progresses and public opinion shifts.
The “Heal Our Heroes Act”
Lawmakers are exploring more targeted approaches. This bill, proposed in 2024, would have:
- Allowed veterans and former first responders to access psilocybin
- Limited access to San Diego, Santa Cruz, and San Francisco counties
- Required use at licensed facilities only
The bill didn’t advance. But the concept could return.
Why This Approach Makes Sense
Many advocates believe starting with a limited therapeutic access program is more politically viable than broad decriminalization. Focusing on specific populations—particularly veterans struggling with PTSD—builds public support.
The Research Continues
Studies show therapeutic potential for:
- Treatment-resistant depression
- End-of-life anxiety
- Addiction
- PTSD
As evidence accumulates, pressure grows for legal pathways to access these treatments. But until California legislators pass new laws—and the governor signs them—magic mushrooms remain in the same legal category as other controlled substances.
What This Means For You
If you’re considering using psilocybin, you should know the risks. Despite decriminalization measures in some cities and growing therapeutic interest, magic mushrooms remain illegal throughout California.
If you’re facing charges related to psilocybin, talking to a defense attorney familiar with California drug laws is the best step. The Nieves Law Firm handles drug-related cases throughout California and can help you understand your options and build a defense strategy.
Policy change takes time. For now, anyone interested in psilocybin should stay informed about legal developments, understand current risks, and make decisions with full awareness of California’s existing laws.
