California has a reputation for being ahead of the curve on plant medicine. Still, when it comes to psilocybin, often referred to as “magic mushrooms”, the laws are more complicated than most people expect. Headlines talk about “decriminalization,” bills are worded differently depending on the city in which they were written, and statewide measures appear and disappear with unnerving regularity.
It’s no surprise that people often struggle to find clarity.
If you’re trying to understand the legal landscape surrounding the use of mushrooms, you’re in the right place. Here’s a grounded, up-to-date explanation of how California currently handles psilocybin, and why people can easily become confused when trying to find this information.
The Short Answer: Are Mushrooms Legal in California?
Right now, psilocybin is not legal in California at the state level. It remains a controlled substance under state law.
What makes things confusing is the number of California cities that have passed decriminalization resolutions, lowering enforcement priority for adult possession of natural psychedelics. Decriminalization isn’t the same as legalization; it doesn’t create a legal market, and it doesn’t guarantee protection from prosecution. It simply signals that some local jurisdictions choose not to target personal possession as aggressively.
What “illegal but partially decriminalized” actually means
When something is illegal, it’s prohibited under the law.
When something is decriminalized, enforcement shifts from “actively pursued” to “lowest priority.” Penalties may still exist, and police discretion remains a factor, but it is not subject to a targeted campaign. In California’s case, statewide law has not changed. Only some cities have adjusted how they enforce it.
Psilocybin vs. other types of mushrooms
The law specifically addresses psilocybin-containing mushrooms. Culinary mushrooms, functional mushrooms, and non-psychoactive species are not part of these regulations. You may have recently seen an influx of conversation related to medicinal mushrooms as well – and to be clear, medicinal mushrooms are not the same as “magic mushrooms.”
Medicinal mushrooms are classified differently and fall into the category of functional mushrooms. Think mushroom types like Cordyceps, Reishi, Chaga, etc. These mushrooms are often found in a variety of product offerings, such as gummies, tinctures, and capsules.

California’s Current Laws on Psilocybin
California treats psilocybin the same way many states do, classifying it as a Schedule I controlled substance. Possession, cultivation, and the sale of psilocybin remain illegal under state law, and there is no regulated program for therapeutic or supervised use.
Under current state codes, psilocybin possession or cultivation can lead to criminal penalties. While enforcement has softened in some regions, the underlying laws haven’t been repealed or replaced.
What decriminalization does and doesn’t do
Decriminalization typically means:
-
Law enforcement may choose not to prioritize cases involving personal possession.
-
Local prosecutors may deprioritize related charges.
-
The city formally recognizes natural psychedelics as a low-enforcement issue.
Decriminalization does not mean:
-
Psilocybin becomes legal.
-
Retail sales or commercial activity are allowed.
-
Cultivation becomes regulated or protected.
-
State-level prosecution is off the table.
Each city establishes its own legal resolution on this matter, so approaches vary by location. Some apply only to personal possession, while others include non-commercial cultivation. In fact, there are specific laws related to growing your own mushrooms. You can learn more about it here: How to Grow Mushrooms at Home: Pros, Cons, and Is It Even Legal?
The key idea is that enforcement becomes less aggressive, not nonexistent. This means there is a “grey area” when purchasing certain mushroom-based products. One of the biggest emerging trends has been microdosing mushrooms – see How to Microdose Mushrooms: A Clear Beginner-Friendly Guide – and the wide range of benefits users report experiencing.
From perceptive creativity and focus to a more centered, balanced approach to everyday life, microdosing has quickly become a tool for those looking to expand their wellness mindset. To learn more, see our buyer’s guide: Where Can I Buy Microdose Mushroom Gummies?
Cities in California That Have Decriminalized Mushrooms
Several California cities have adopted local measures adjusting their approach to the possession and use of psychedelics as a whole.
Oakland
In 2019, Oakland became the first U.S. city to decriminalize natural entheogens. The resolution deprioritized adult possession and non-commercial cultivation.
Santa Cruz
Santa Cruz followed Oakland’s lead shortly after, focusing primarily on personal possession for adults.
San Francisco
In 2022, San Francisco passed a resolution encouraging law enforcement to make naturally occurring psychedelics their lowest priority.
How local decriminalization differs from state law
Local resolutions don’t override state law. These policy statements are used to direct local enforcement agencies, but aren’t necessarily reflective of changes in statewide law.
Recent Ballot Measures and Legislative Attempts
California lawmakers have made multiple attempts to change statewide policy on psychedelics. These efforts have attracted considerable public interest, but none have yet created a legal, regulated psilocybin framework.
Proposals such as SB-58 aimed to decriminalize certain psychedelics at the state level or create pathways for regulated access. These bills gained attention but ultimately did not become law. Previous bills have stalled in the past due to common reasons like:
-
Concerns about public health implications
-
Lack of consensus on regulatory details or gaps in how the bill addressed key issues
-
Unclear distinctions between therapeutic use and broad adult access
However, just because these bills have stalled in the past doesn’t mean there won’t be another push for different legalization. Especially as emerging categories continue to capture consumer interest, California will likely continue debating:
-
Regulated therapeutic models
-
Decriminalization with safety guidelines
-
Expanded research access
Nothing is guaranteed, but the current momentum behind the decriminalization movement suggests this conversation isn’t going away.
How California Compares to Other States
California is often assumed to be the most progressive state on plant medicine, but the national picture shows a more varied landscape.
Oregon and Colorado have created structured programs for therapeutic or supervised use. These frameworks are still developing, but they represent the first state-level projects that facilitate non-criminal access to psilocybin. New Jersey recently passed an experimental bill that would allow patients to seek medical use of psilocybin. You can read more here: Are Mushrooms Legal in New Jersey?
What makes California’s path unique
California’s approach has been more city-driven than state-driven. Instead of sweeping statewide change, policy shifts here often begin with local resolutions before broader legislative efforts gain traction.

Why So Many People Are Confused About Mushroom Laws
Headlines from Californian news outlets often suggest major policy shifts, even when the actual legal changes may be minimal or largely symbolic. Terms like “legal,” “decriminalized,” or “approved” are sometimes used loosely. Policy announcements can create impressions that differ from the actual legal text.
A city itself can deprioritize enforcement, but the state still sets criminal statutes. Without a statewide bill, the legal foundation remains unchanged.

Psilocybin is not legal in California today. Some cities have chosen to treat natural psychedelics as low-priority issues, but this isn’t the same as legalization. California continues to debate broader changes, and new proposals surface regularly, but, for now at least, the same laws remain in place.
Understanding the difference between statewide law, local policy, and future proposals helps you to cut through any ambiguity relating to this issue. As the conversation evolves, keeping an eye on official state channels is the best way to stay informed.
