Oregon psilocybin centers follow screening rules, but the median session costs $1,900

Oregon's licensed psilocybin service centers are sticking to the state's safety screening rules, but a session is expensive and insurance doesn't cover it. That's the finding of a mystery-shopper study by WashU Medicine researchers, published in Health Affairs Scholar and announced by WashU Medicine on October 12, 2026. Posing as prospective clients, the researchers reached 15 of Oregon's 22 active centers. The median session cost was $1,900, and no center accepted insurance.

What the mystery shoppers found

Every center the researchers reached followed Oregon's screening rules, and none would let a client take psilocybin home. That second point matches how the program is built: under Measure 109, adults 21 and older can take psilocybin only at a state-licensed service center with a licensed facilitator.

Why the price matters

Because no center took insurance, clients pay that $1,900 median out of pocket. The price adds context to the largest real-world study of the program so far. In August 2026, an OHSU-led study in JAMA Network Open followed about 346 adults who used licensed service centers. More than half reported improved mental health symptoms, and there were four serious adverse reactions, all in first-time users. Outside experts cautioned that the study was uncontrolled and that its sample was affluent.

The program's own finances are under pressure too. The Oregon Health Authority (OHA) had proposed doubling annual license fees and ending fee discounts for veteran and low-income licensees. After unanimous opposition at two public hearings, OHA said on September 22, 2026 that it "will not adopt the proposed fee increases." The agency is still weighing a higher 15% psilocybin product tax and faces a projected multimillion-dollar budget shortfall, the Oregon Capital Chronicle reported.

How Oregon's program works

Measure 109 (2020) created Oregon Psilocybin Services. State law bars sales to anyone under 21 and bars people under 21 from licensed premises. The first service center was licensed on May 5, 2023. Outside that system, possessing psilocybin has been a misdemeanor again since September 1, 2024, when HB 4002 replaced the earlier Class E violation. Psilocybin is still a Schedule I drug under federal law.

More change is scheduled. HB 4040, signed April 7, 2026, will accept out-of-state facilitator training starting January 1, 2027, and Colorado training programs qualify. It also expands dual licensure to more professional boards, including occupational and physical therapy, and adds a low-dose data reporting point. OHA plans a new rulemaking for its other pending rule changes, targeting January 15, 2027.
