Oregon
Psilocybin is legal in Oregon for adults 21 and over at a state-licensed service center, where they take it under a licensed facilitator's supervision and leave with none. Nothing is sold at retail or on prescription, and possessing psilocybin anywhere outside the program is still a crime.1

1. What the law is
Licensed service centers have been running in Oregon since 2023, and the state is now widening who may sit with a client. HB 4040, signed in April 2026, lets occupational and physical therapy licensees train as psilocybin facilitators, and from January 1, 2027 it opens Oregon licensure to facilitators trained under other states' approved programs.
Voters approved Measure 109 in November 2020. Service centers began operating in summer 2023. An adult books a preparation session with a licensed facilitator, takes psilocybin at a licensed service center under supervision, then returns afterward for an integration session. Nothing is prescribed and nothing goes home. The Oregon Health Authority reported 5,935 clients in 2025 and 952 more in the first quarter of 2026, and approved 377 facilitator licenses and 25 service center licenses over the course of 2025.
Colorado adopted a comparable supervised-access framework under Proposition 122 in 2022. No other US state has opened one since. Oregon's program rules are revised annually by the health authority, so licensing terms change more often than the statute does.

5. Common questions
Are mushrooms legal in Oregon?
Within one program, for adults 21 and over. Measure 109 lets a client buy, possess and consume psilocybin at a licensed service center during a supervised administration session, after a preparation session with a licensed facilitator, and the law confines all three acts to the service center itself. Mushrooms bought anywhere else, grown at home or carried out the door fall under Oregon's ordinary drug laws.
Can you buy mushrooms in Oregon?
The one lawful sale is to a client at a licensed service center during an administration session, and the Oregon Health Authority's own guidance says products may not be purchased and taken off-site. Oregon issues no retail license for psilocybin, so a shop, dispensary or website selling mushrooms or mushroom gummies to the public is outside the state program.
Is psilocybin therapy legal in Oregon?
Oregon licenses psilocybin services, and the informed consent form every client signs states that they are not a medical or clinical treatment and need no diagnosis or referral. Facilitators hold a facilitator license, and the rules bar them from diagnosing or treating physical or mental health conditions during services, with one exception: a facilitator who also holds a health license, such as a nurse or a psychologist, may provide that care during preparation and integration sessions after notifying the state and telling the client first.
Who can prescribe psilocybin in Oregon?
No one prescribes it. A client books directly with a licensed service center without a prescription or medical referral, and federal law does not allow psilocybin to be prescribed at all, because it has no FDA approval and remains in Schedule I of the Controlled Substances Act.
Do you have to live in Oregon to use a service center?
Residency is not required. The Oregon Health Authority says clients do not need to live in Oregon, and a visitor goes through the same steps as a resident: proof of being 21 or older, a preparation session with a licensed facilitator, a plan for getting home afterward, and the administration session itself at a licensed service center.
How much does psilocybin cost in Oregon?
The state sets no prices. The Oregon Health Authority says it has no authority to set or regulate what service centers and facilitators charge, so each center sets its own. The state does set the license fees businesses pay, and those are unchanged. On 22 Sep 2026 the authority withdrew proposed increases that would have doubled the main ones, and its other proposals go to a new rulemaking planned to take effect 15 Jan 2027.
Is psilocybin still decriminalized in Oregon?
Possession became a crime again on 1 Sep 2024, when House Bill 4002 replaced the non-criminal violation that Measure 110 had created. Possessing psilocybin outside the licensed program is now a drug enforcement misdemeanor, sentenced by default to probation of up to 18 months, while 12 grams or more is a Class A misdemeanor and making or delivering it without a license is a Class A felony.
Can you grow mushrooms at home in Oregon?
Oregon's psilocybin law counts planting, cultivating and harvesting as manufacture, and only a licensed manufacturer may do it. Growing psilocybin mushrooms at home without that license is manufacturing a Schedule I substance under the state's general drug statute, a Class A felony.
Where can you find a licensed service center in Oregon?
The Oregon Health Authority's licensee directory lists the service centers that agreed to be named, a list that is not complete, and its license status search confirms a license by number. Cities and counties may ban service centers and manufacturers by a vote at a statewide general election, and the health authority keeps a spreadsheet of those local ordinances.
Is Oregon's psilocybin program legal under federal law?
Federal law is unchanged by it. Psilocybin is still a Schedule I controlled substance, and the consent form Oregon requires every client to sign says federal law prohibits its manufacture, distribution and possession even in states that allow it.
Are magic mushrooms ("shrooms") legal in Oregon?
"Magic mushrooms" and "shrooms" are common names for fungi that contain psilocybin, and this entry states the law on psilocybin itself, which some laws treat separately from the fungus. Psilocybin is legal in Oregon for adults 21 and over at a state-licensed service center, where they take it under a licensed facilitator's supervision and leave with none. Nothing is sold at retail or on prescription, and possessing psilocybin anywhere outside the program is still a crime.

Correction. An update dated 15 September 2026 recorded the fees in Oregon's proposed psilocybin rules, among them a facilitator licence rising from $2,000 to $4,000 a year and service center and manufacturer licences rising to $20,000. Those amounts were already public in the proposed rule text Oregon filed with the Secretary of State on 28 August 2026, which an earlier update records; 15 September was the day of the first public hearing and the day the figures reached us. Oregon has since dropped the increases, and its legal status is unchanged.
Portland's City Council voted on 30 September 2026 to make the personal, non-commercial use of natural psychedelics, including psilocybin mushrooms, a low priority for law enforcement. The ordinance takes effect on 30 October 2026, excludes peyote and allows no sales. Oregon state law is unchanged.
A note on method for the entry of 22 September 2026: the Oregon Health Authority statement it reports was read in full on 28 September 2026, as the HTML its web page served. Nothing in that entry changes, and Oregon's legal status is unchanged.
Oregon will not raise psilocybin licence fees after all. On 22 September 2026 the Oregon Health Authority said it is dropping the rulemaking that proposed doubling the main licence fees from 1 January 2027 and will not adopt the increases, so the fees businesses pay today stay as they are. The changes in that package that had nothing to do with fees go into a new rulemaking the authority plans to start in the coming weeks, aiming for them to take effect on 15 January 2027. Oregon's legal status is unchanged.
Oregon's proposed rule text now puts figures on the fee increase. A facilitator licence would cost $4,000 a year, up from $2,000, service center and manufacturer licences would double to $20,000, and a worker permit would go from $25 to $200, while the reduced fees now available to nonprofits, veterans and applicants on public benefits would be removed. The state's filed notice says the increases would take effect on 1 January 2027, with laboratories paying the higher fee only from 2029, and it expects the change may shrink the number of licensees. Nothing is final until Oregon adopts the rules, and written comments close on 21 September 2026.
Two Oregon licensing figures are corrected. The state approved 377 facilitator licences and 25 service center licences during 2025, and those figures count approvals granted across the year. They are not a roster of licences held at its end, and the health authority publishes no year end count. How many people received services is unchanged, at 5,935 in 2025 and 952 in the first quarter of 2026. Oregon's legal status is unchanged.
Oregon's psilocybin and medical marijuana programmes are now one section of the state health authority. On 1 September 2026 the Oregon Health Authority merged Oregon Psilocybin Services and the Oregon Medical Marijuana Program into a Medical Cannabis & Psilocybin section led by the psilocybin programme's existing manager, and the state says services and processes carry on without disruption while forms and web pages take the new name over the coming months.
Oregon took public comment on a petition to change the rule that governs how psilocybin facilitator training programmes get their curriculum approved. The comment period closed on 29 August 2026. This is a separate track from the state's larger annual rule changes.
Oregon has filed the formal notice for its 2026 psilocybin rule changes. The proposed rules would double licence fees and end the reduced fees used by nonprofits, veterans and people receiving SSI or SNAP, which accounted for about thirty two percent of licence transactions this biennium. The state says the programme was meant to pay for itself and does not. Comments close on 21 September 2026, with public hearings on 15 and 16 September. The same rules carry House Bill 4040, which would let Oregon recognise facilitator training approved by other states.
Oregon has opened a public comment period on new psilocybin rules that would change all licence fees and end reduced fees. Comments run from 1 to 21 September 2026, with public hearings on 15 and 16 September. The state gives rising costs and programme sustainability as the reason.
Oregon's entry now cites the session law rather than a bill overview page that did not carry the dates the entry published. The facts are the same; the citation now proves them.
Oregon is taking public comment on a petition to change the rule that sets how facilitator training courses are approved. Comments close 29 Aug 2026. The program itself is unchanged.
Oregon's pending bill list is cleared. HB 4040 is enacted and HB 4110 died in committee.
Oregon's psilocybin program laid out its 2026 rule changes: proposed rules publish 1 Sep 2026 and restructure all fees, including ending reduced fees. Public comment runs 1 to 21 Sep, with hearings 15 and 16 Sep. The program's legal status is unchanged.
Oregon's status held. HB 4040, which widens who may be licensed as a facilitator, became law in April 2026, and the ibogaine bill HB 4110 died in committee, so neither is listed as pending any more.
