Are Psilocybin Mushrooms Legal in the United States?
Psilocybin mushrooms remain a Schedule I controlled substance under federal law, which means possession, sale, and use are illegal at the national level. However, a growing number of states and cities have passed their own measures to either legalize regulated therapeutic use or decriminalize personal possession.
The result is a patchwork of laws that changes from state to state, and sometimes from city to city. This guide breaks down exactly where psilocybin stands in 2026 so you can stay informed.
Federal Status: Still Schedule I
Under the Controlled Substances Act, psilocybin and psilocin are classified as Schedule I substances, the most restrictive category. This classification means the federal government considers psilocybin to have a “high potential for abuse” and “no currently accepted medical use.”
That said, federal enforcement of personal psilocybin possession has historically been rare. Most enforcement action is handled at the state and local level, which is where the real differences emerge.
Meanwhile, the FDA has granted Breakthrough Therapy designation to psilocybin-assisted therapy for treatment-resistant depression, signaling a shift in how the medical establishment views these compounds. Clinical trials from Johns Hopkins University and NYU Langone Health continue to produce promising results for depression, PTSD, and end-of-life anxiety.
States Where Psilocybin Is Legal for Therapeutic Use
Oregon: The First State to Legalize Psilocybin Therapy
Oregon made history in 2020 when voters passed Measure 109, creating the nation’s first regulated psilocybin therapy program. Licensed psilocybin service centers began operating in 2023, and the program continues to expand in 2026.
Here is what Oregon’s program looks like:
- Legal for supervised therapeutic sessions at licensed service centers
- No prescription or diagnosis required; adults 21 and older can access services
- Sessions include a preparation visit, a facilitated psilocybin experience, and an integration session
- Microdose sessions start around $25, while full-dose sessions typically begin at $350
- Personal possession and recreational use are still illegal outside of licensed settings
Oregon simultaneously passed Measure 110, which decriminalized personal possession of small amounts of all drugs, though this measure was partially rolled back in 2024.
Colorado: Natural Medicine Health Act
In November 2022, Colorado voters approved Proposition 122, the Natural Medicine Health Act. This law does two things:
- Decriminalizes personal possession, use, and cultivation of psilocybin, psilocin, DMT, ibogaine, and mescaline (excluding peyote) for adults 21+
- Establishes a regulated system for licensed healing centers, with the framework rolling out through 2026
Colorado’s approach is broader than Oregon’s because it covers multiple natural psychedelic compounds and allows personal cultivation. The state’s Natural Medicine Division continues to develop rules for the therapeutic access program.
States and Cities That Have Decriminalized Psilocybin
Decriminalization is different from legalization. When a city or state decriminalizes psilocybin, it means enforcement of possession laws becomes the lowest priority for local police. You can still technically be charged, but law enforcement has been directed to focus resources elsewhere.
City-Level Decriminalization
Several cities have taken matters into their own hands:
- Denver, Colorado (2019): The first U.S. city to decriminalize psilocybin mushrooms. Passed Initiative 301, making personal possession and use the lowest law enforcement priority for adults 21+.
- Oakland, California (2019): Decriminalized all entheogenic plants and fungi, including psilocybin, ayahuasca, and mescaline-containing cacti.
- Santa Cruz, California (2020): Followed Oakland’s lead in decriminalizing entheogenic plants and fungi.
- Ann Arbor, Michigan (2020): Made enforcement of laws against entheogenic plants and fungi the city’s lowest priority.
- Washington, D.C. (2020): Voters passed Initiative 81, making enforcement of laws against entheogenic plants the lowest policing priority.
- Somerville, Massachusetts (2021): Decriminalized all entheogenic plants.
- Cambridge, Massachusetts (2021): Passed a similar resolution to Somerville.
- Northampton, Massachusetts (2021): Decriminalized entheogenic plants.
- Seattle, Washington (2021): City council passed a resolution making psilocybin enforcement the lowest priority.
- Detroit, Michigan (2021): Voters approved Proposal E, decriminalizing entheogenic plants and fungi.
- San Francisco, California (2022): The Board of Supervisors passed a resolution urging deprioritization of enforcement.
Important note: Even in decriminalized cities, psilocybin remains illegal under both state and federal law. Decriminalization only affects local enforcement priorities.
State-Level Decriminalization Efforts
Beyond Oregon and Colorado, several states have introduced or advanced psilocybin-related legislation:
- Massachusetts: Multiple cities have decriminalized, and statewide ballot initiatives for therapeutic access continue to gain momentum.
- California: SB 58, which would have decriminalized personal possession and facilitated use of psilocybin, narrowly failed after a gubernatorial veto in 2023. New legislative efforts continue in 2026.
- Connecticut: Has introduced bills exploring a regulated therapeutic framework.
- New Jersey: Proposed legislation for psilocybin-assisted therapy pilot programs.
- New York: Bills have been introduced to create therapeutic access programs, though none have passed yet.
- Hawaii: Established a task force in 2022 to study therapeutic psilocybin use and make recommendations.
- Minnesota: A psychedelic therapy task force was created to explore regulatory options.
States Where Psilocybin Is Strictly Illegal
In the majority of U.S. states, psilocybin mushrooms are fully illegal with no exceptions for therapeutic or personal use. Penalties vary widely:
- Felony possession states: In states like Texas, Florida, Georgia, and Alabama, possession of any amount of psilocybin mushrooms can result in felony charges, significant fines, and prison time.
- Misdemeanor possession states: Some states treat small-amount possession as a misdemeanor, but penalties can still include jail time and fines.
- Enhanced penalties for distribution: Manufacturing, growing, or selling psilocybin mushrooms carries heavier penalties in every state where it remains illegal, often including mandatory minimum sentences.
Key Factors Shaping Psilocybin Law in 2026
Clinical Research and FDA Approval
The FDA’s Breakthrough Therapy designation has accelerated clinical trials. Major research institutions continue to publish results showing psilocybin-assisted therapy can be effective for:
- Treatment-resistant depression
- End-of-life anxiety and existential distress
- PTSD and trauma
- Alcohol and tobacco addiction
A full FDA approval of psilocybin-assisted therapy could fundamentally change the legal landscape. If approved as a prescription medication, psilocybin would likely be rescheduled from Schedule I to a less restrictive category.
The Difference Between Psilocybin and “Magic Mushroom” Spores
An important legal nuance: in most states, psilocybin mushroom spores are technically legal because they do not contain psilocybin or psilocin. However, cultivating those spores into mature mushrooms is illegal in most jurisdictions. The exceptions are California, Georgia, and Idaho, where spores themselves are also illegal.
What About Mushroom Products Sold Online?
You may see “mushroom” products marketed for wellness, focus, or mood support. These typically fall into two categories:
- Functional mushroom supplements (lion’s mane, reishi, chaga, cordyceps): These are completely legal and widely available. They do not contain psilocybin.
- Psilocybin-containing products: These are illegal to sell in most states, regardless of how they are marketed. Be cautious of products making euphoric or psychedelic claims without clearly stating their ingredients.

Frequently Asked Questions
Is it legal to buy psilocybin mushrooms online?
In most states, no. Purchasing psilocybin mushrooms online is illegal under federal law and in the vast majority of states. Oregon allows access through licensed service centers, and Colorado permits personal use for adults 21+, but neither state has legal retail sales.
Can I grow psilocybin mushrooms at home?
Colorado is currently the only state where adults 21+ can legally cultivate psilocybin mushrooms for personal use. In all other states, cultivation is illegal and can carry felony charges.
What is the penalty for psilocybin possession?
Penalties vary by state. In some states, possession of any amount is a felony that can carry years in prison. In others, small amounts may be treated as a misdemeanor. In Oregon and Colorado, possession has been either legalized (in therapeutic settings) or decriminalized.
Will psilocybin become federally legal?
There is no timeline for federal legalization. However, the FDA’s Breakthrough Therapy designation and ongoing clinical trials suggest a path toward rescheduling is possible if psilocybin-assisted therapy receives full FDA approval.
Are psilocybin retreats legal in the United States?
Only in Oregon, where licensed psilocybin service centers operate under state regulation. Colorado is developing its regulated healing center framework. All other “psilocybin retreats” operating in the U.S. are not legally sanctioned.
