Psilocybin law in Michigan
Decriminalised or deprioritised Checked 26 October 2026
Psilocybin is illegal in Michigan: it is a Schedule 1 controlled substance under MCL 333.7212, though Ann Arbor, Detroit and several other cities have made entheogenic plants a lowest enforcement priority.
Psilocybin is still illegal, but state law reduces the penalty for personal possession, or one or more cities or counties have made it a lowest enforcement priority. Supplying it remains a crime. A summary of published sources, not legal advice.
Source status: Prohibited. Psilocybin remains a Schedule I drug under US federal law.
