1. What the law is
Measure 109 (Oregon Psilocybin Services Act), codified as ORS 475A; amended by HB 4040 (2026), enrolled as 2026 Oregon Laws chapter 109, approved by the Governor and filed with the Secretary of State April 7, 2026, effective on passage. Sections 36 to 38 amend ORS 475A.325, 475A.338 and 475A.372; section 39 makes those amendments operative January 1, 2027.1
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. The Oregon Psilocybin Services Act, Measure 109, remains the framework.
Oregon is the first U.S. state to legalize regulated psilocybin services. In November 2020, voters passed Measure 109 (the Oregon Psilocybin Services Act), directing the Oregon Health Authority (OHA) to create a licensing framework for psilocybin-assisted therapy. After a two-year development period, licensed service centers began operating in summer 2023. The model is not retail or recreational: clients must complete a preparation session with a licensed facilitator, consume psilocybin at a licensed service center under supervision, and complete an integration session afterward. Oregon also passed Measure 110 in the same election, which decriminalized possession of small amounts of all drugs, though this measure has since been partially rolled back. As of 2026, Oregon remains the most advanced psilocybin access model in the country, with over 20 licensed service centers operating statewide.
Oregon's regulatory model has become the blueprint for other states considering psilocybin legislation. Colorado's Proposition 122 (2022) adopted a similar supervised-access framework. Several other states have introduced bills modeled on Oregon's approach. The OHA continues to refine licensing rules, and the legislature has introduced additional bills in 2026 addressing ibogaine prescribing (HB 4110) and expanded program access (HB 4040).

Oregon's pending bill list is cleared. HB 4040 is enacted and HB 4110 died in committee.
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 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 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.
