Michigan Lawmaker Files Bill to Decriminalize Psilocybin and Psilocyn for PTSD Patients

State Representative Mike McFall (D) has introduced legislation that would allow adults diagnosed with post-traumatic stress disorder (PTSD) to legally possess small amounts of psilocybin and psilocyn, the psychedelic compounds found in magic mushrooms.

Psilocybin mushrooms.

The bill, filed yesterday with six Democratic cosponsors, has been referred to the House Committee on Families and Veterans.

House Bill 4686 proposes amending the state’s public health code to create exemptions from criminal penalties for individuals who meet specific criteria. Under the bill, adults aged 18 and older would be allowed to possess up to 2 ounces of a substance containing psilocybin or psilocyn, provided it is strictly for personal use and accompanied by medical documentation of a PTSD diagnosis.

The bill outlines nearly identical provisions for both psilocybin and psilocyn, clarifying that individuals who meet the requirements would not be in violation of existing controlled substance statutes, including sections 7401, 7403, and 7404 of the Michigan Public Health Code, which currently prohibit the possession and use of these substances.

Supporters of the measure argue that psychedelics like psilocybin have shown promise in clinical trials for alleviating symptoms of PTSD, depression, and anxiety. McFall and his colleagues hope the legislation will provide a new therapeutic option for those struggling with trauma, particularly military veterans.

If approved by the committee and passed by the full legislature, Michigan would join a growing number of states and localities exploring psychedelic reforms focused on mental health treatment.
