Mushroom shops in Corvallis, Oregon

Oregon became the first U.S. state to legalize supervised psilocybin services when voters passed Measure 109 in 2020. The Oregon Health Authority (OHA) began licensing service centers, facilitators, manufacturers, and testing labs in 2023. Adults 21+ can legally consume psilocybin at a licensed service center under the guidance of a trained facilitator — no medical diagnosis or referral required.

Practically, that means three different kinds of shop can show up in a search for "mushroom dispensary near me" in Corvallis: state-licensed psilocybin providers (only in Oregon and Colorado), gray-market shops in decriminalized cities, and legal Amanita muscaria retailers that can operate almost anywhere. We tag each one so you know what you're walking into. Read more in our Oregon guide.
