Psilocybin law and access in Washington

A concise, source-dated explanation of statewide law, regulated access, and the difference between state and local policy.

Laws and implementation can change quickly. This page is educational information, not legal advice.

Possession

Statewide legal status

Washington lists psilocybin and psilocyn as Schedule I controlled substances. Unauthorized possession remains unlawful; Washington has not enacted statewide personal-use decriminalization.

Regulated access

Programs and services

Washington has no general statewide psilocybin service-center, dispensary, or retail program.

Current context

Controlled · narrow research pilot

A 2023 law directed the University of Washington to establish a narrow pilot, subject to funding and federal requirements. It did not create general consumer access.

What local policy means

Washington has documented municipal actions in Seattle and Tacoma. Those actions affect local priorities only; they do not create statewide legalization, licensed retail, or medical suitability.

Cities covered by the Washington guide

The statewide explanation above covers Bellevue, Bellingham, Everett, Kirkland, Seattle, Spokane, Tacoma and Vancouver. A separate page appears below only where a documented municipal action adds material local context.

Sources used for this review

The statewide baseline was checked against Washington’s controlled-substance and possession provisions and the enacted, partially vetoed 2023 bill that retained a task force and narrow University of Washington pilot.
