Is psilocybin legal where you live?

All 50 states and DC, sorted by what you can actually do — not by what the headlines imply. Two states have legal supervised access. Most do not, and several are widely listed as reformed when they are not.

The short answer

As of 30 August 2026, psilocybin remains a Schedule I controlled substance under the federal Controlled Substances Act. It has not been approved by the FDA and has not been rescheduled by the DEA. Under state law, 2 states (Oregon and Colorado) run legal supervised-access programs, 1 (New Mexico) is building one, 7 fund research or pilot access only, and 7 have cities that deprioritized enforcement without changing state law. In 34 it is simply illegal.

Decriminalized is not legal

Three words get used interchangeably and only one of them means you will not be arrested. The gap between them is where people get hurt.

Federal law has not changed, whatever 2026 felt like

2026 has been the most eventful year in the history of American psychedelic policy and almost none of it has changed what is legal. An executive order, three FDA priority vouchers, a federal directive to the states — all real, none of them rescheduled anything. We keep the full ledger of what each action did and did not do on the federal policy page.

Three states that national trackers get wrong

We check other trackers, and three errors circulate widely enough to be worth naming.

  • Nevada is not decriminalized. SB 242 was amended before passage to create a working group and nothing more. The “four ounces, adults 18+” language that appears in several trackers comes from the introduced bill, not the enacted law.
  • Connecticut is not decriminalized. Decriminalization bills passed the House in 2023 and again in 2025 and died in the Senate both times. Connecticut’s real reform is a therapy pilot, which is a different thing.
  • Rhode Island is not decriminalized. The 2023 bill passed one chamber; the 2026 successor was withdrawn.

We flag these inside the relevant state entries too. If you find an error in ours, tell us — corrections are logged publicly under our editorial standards.

Deprioritization is not protection

Roughly two dozen US cities have made enforcement against entheogenic plants and fungi the lowest law-enforcement priority. None of them changed a statute. Possession remains a criminal offense in all of them, prosecutors retain discretion, and federal jurisdiction is untouched. If you are relying on a city resolution as legal cover, you do not have legal cover — we set out exactly what each category permits on its own page.

Where the two real programs stand

Oregon’s program, created by Measure 109 in 2020, has served more than 20,000 people since opening in mid-2023. It requires no diagnosis and no prescription — an adult 21 or over books a session at a licensed service center. In August 2026, JAMA Network Open published the first real-world outcomes study of a legal US program: 346 clients across 24 service centers, with 91.5% reporting benefit at one month and 2% describing the experience as harmful at three months.[1] It is observational rather than randomized, and the authors note participants were healthier than typical trial populations — so it tells you what happens in practice, not how well the treatment works against a control.

Colorado went further in one respect: Proposition 122 made personal possession, cultivation and gratuitous sharing lawful for adults 21+, alongside a licensed healing-center system that issued its first license in April 2025. New Mexico’s Medical Psilocybin Act is the one to watch — producer applications opened on 17 August 2026, and the state is targeting first patient access by the end of the year.

Common questions

Questions people actually ask

The four that come up most. Twenty more, grouped by topic, are on the questions page.

Is psilocybin legal in the United States?
No. Psilocybin remains a Schedule I controlled substance under federal law as of August 2026. It has not been approved by the FDA and has not been rescheduled by the DEA. Two states — Oregon and Colorado — operate legal supervised-access programs under state law, but participation there does not protect you under federal law.
Which states have legal psilocybin?
Oregon and Colorado are the only two states where an adult can legally take psilocybin at a licensed site with a trained facilitator. New Mexico has passed a medical psilocybin law and began accepting producer applications in August 2026, but no patient can be treated there yet.
What is the difference between decriminalization and legalization?
Decriminalization reduces or removes criminal penalties. What most US cities have actually done is narrower still: deprioritization, which instructs police to treat enforcement as their lowest priority. State law is unchanged, the conduct remains illegal, and you can still be arrested and prosecuted — including federally. Legalization, as in Oregon and Colorado, creates an affirmatively lawful route.
What is a psilocybin trigger law?
A trigger law is a state statute already on the books that automatically changes psilocybin's state status once the FDA approves a psilocybin medicine and the DEA reschedules it. Arizona, South Dakota, Virginia and Georgia have versions of this. Because neither federal event has happened, these laws currently create no access at all.
