Michigan
Psilocybin legal status, legislation & access — 2025
Enforcement context
Psilocybin is a Schedule I controlled substance under Michigan law with no statewide decriminalisation or therapeutic access framework. A wave of local ordinances passed between 2020 and 2023 significantly reduced enforcement in the Detroit metro area. Ann Arbor decriminalised the cultivation, possession, and use of entheogenic plants and fungi by unanimous City Council vote in September 2020 — one of the earliest US cities to act. Detroit voters approved Proposal E in November 2021, decriminalising entheogenic plants and fungi at the local level. Hazel Park followed on March 22, 2022, and Ferndale followed on February 27, 2023. State-level possession still carries criminal penalties in jurisdictions without a local ordinance or deprioritisation policy.

Frequently asked questions
Is psilocybin legal in Michigan?
Psilocybin is a Schedule 1 controlled substance in Michigan. However, Ann Arbor, Detroit, Ferndale, and Hazel Park have each enacted local decriminalisation ordinances making personal possession the lowest law-enforcement priority within those cities.
When did Ann Arbor decriminalise psilocybin?
Ann Arbor City Council voted unanimously to decriminalise entheogenic plants and fungi in September 2020, making it one of the first US cities to take this step. The resolution makes enforcement of personal possession the city's lowest law-enforcement priority and directs no city resources toward prosecution.
Has Detroit decriminalised psilocybin?
Detroit passed a decriminalisation resolution in December 2021, making personal possession and use of entheogenic plants and fungi the lowest law-enforcement priority in the city. The resolution does not legalise possession under Michigan state law — psilocybin remains illegal at the state level — but directs Detroit police not to enforce state law for personal-use quantities.
