Psilocybin (the active compound in “magic mushrooms”) is legal for supervised use in Oregon, making it the first state in the U.S. to create a regulated system for psilocybin services. Other psychedelics, including LSD and MDMA, remain illegal. The legal landscape is more nuanced than a simple yes or no, so here’s what you need to know.
How Oregon’s Psilocybin Program Works
Oregon voters passed Ballot Measure 109 in November 2020, creating a first-of-its-kind regulatory framework for psilocybin. Now codified as ORS 475A, the law allows adults 21 and older to consume psilocybin at licensed service centers under the supervision of a trained facilitator. The Oregon Health Authority oversees the entire program, from licensing facilitators and service centers to regulating the products themselves.
This is not a recreational legalization model. You cannot buy psilocybin at a dispensary, take it home, or use it on your own. Every session happens on-site at a licensed facility, guided by a licensed facilitator who stays with you throughout the experience.
What a Psilocybin Session Looks Like
You do not need a prescription, a medical diagnosis, or a referral from a doctor. The only hard requirement is being 21 or older. There is also no residency requirement for clients, so visitors from other states can legally access psilocybin services in Oregon.
A session typically involves a preparation period, the administration session itself, and an integration conversation afterward. During the administration session, the maximum dose is 50 mg of psilocybin, including any secondary doses you might take during the same visit. That 50 mg cap also applies to any 24-hour period, so you cannot move between centers to consume more. Doses can be split across multiple packages. For example, a 20 mg dose could come as two 10 mg servings.
Service centers can range in size and layout. Some include outdoor spaces for the experience, as long as those areas have clearly defined boundaries and are free from hazards. Centers must be located at least 1,000 feet from a school, with some exceptions when a physical barrier like a highway or river separates the two.
Not Every Part of Oregon Allows It
Oregon law gave cities and counties the power to restrict or ban psilocybin businesses within their borders. Several jurisdictions have done exactly that. Clatsop County, for instance, passed a temporary moratorium on psilocybin growing, processing, and administration in unincorporated areas in 2022, then replaced it with a more permanent ordinance in late 2024. Rules vary significantly between cities and counties, so the fact that psilocybin services are legal statewide does not mean a service center exists near every community. If you’re looking into a specific area, checking with the local government is a practical first step.
Other Psychedelics Are Still Illegal
Oregon’s regulated framework applies only to psilocybin. LSD, MDMA, DMT, mescaline, and other psychedelics remain controlled substances under both state and federal law. Possessing them can result in criminal charges.
Oregon did briefly take a more lenient approach to personal drug possession under Measure 110, passed the same year as the psilocybin law, which reduced possession of small amounts of any drug to a civil violation. That experiment was short-lived. In 2024, the state legislature passed HB 4002, which re-established criminal penalties for unlawful drug possession effective September 1, 2024. Possession is now classified as a “drug enforcement misdemeanor,” though the law includes a conditional discharge process that can lead to sealed records.
Ketamine occupies a separate legal space. It is a federally approved medication that licensed medical providers in Oregon can administer for therapeutic purposes, including through naturopathic doctors who meet specific continuing education requirements. Ketamine therapy operates under standard medical licensing, not under the psilocybin services framework.
The Federal Conflict
Psilocybin remains a Schedule I controlled substance under federal law, which classifies it as having no accepted medical use and a high potential for abuse. Oregon’s program exists in a legal gray area similar to state-legal marijuana: technically in conflict with federal law, but operating on the expectation that the federal government will not intervene. So far, the Department of Justice has not taken enforcement action against Oregon’s licensed psilocybin operations, following the same hands-off pattern it has largely maintained with state marijuana programs.
This matters for a few practical reasons. Psilocybin service centers cannot use the federal banking system as easily as other businesses. And anyone working in or using the system should understand that federal law has not changed, even though state law permits it. The risk of federal prosecution appears low based on current enforcement trends, but the legal tension is real and unresolved.
Cost and Practical Access
Because psilocybin services operate outside the medical system, health insurance does not cover them. Sessions typically cost several hundred to over a thousand dollars when you factor in preparation, the administration session, and integration. The state legislature included language about making services “safe, accessible and affordable,” but affordability remains one of the biggest barriers for most people interested in trying it. The number of licensed service centers is still growing, with availability concentrated in the Portland metro area and a handful of other communities.
