Oregon Measure 109: What it does and doesn't permit

In November 2020, Oregon became the first state to create a regulated psilocybin services framework. Understanding exactly what the law permits — and what it doesn't — is essential for anyone considering access.

What the law actually says

Measure 109 created two new license categories: psilocybin service centers and psilocybin facilitators. Both are regulated by the Oregon Health Authority. The law deliberately separates psilocybin services from the medical system — no prescription, diagnosis, or physician referral is required.

Clients must be 21 or older, undergo a preparation session with their facilitator before the service session, and remain on-site for the duration of the experience. Facilitators are required to be present throughout.

Critically, the law does not permit the sale of psilocybin products for home use, nor does it create any protection under federal law. Interstate transport of psilocybin — even to receive services in Oregon — remains federally illegal.

Quick Reference
Do I need a doctor's referral?
No. Oregon's framework does not require a prescription or medical diagnosis. It's a services model, not a medical one.
Can I take psilocybin home?
No. The law only permits consumption at a licensed service center under facilitator supervision. Home use is not permitted.
Is it legal to fly to Oregon for treatment?
Flying to Oregon to access services is legal. However, you cannot legally transport psilocybin across state lines under federal law.
Does insurance cover it?
Not currently. Psilocybin services are cash-pay only. Some centers offer sliding scale fees or scholarship programs.
