Enforcement Reality
While several cities in Massachusetts have decriminalized psilocybin, it remains illegal at the state level. Enforcement varies by jurisdiction, with some local police departments deprioritizing prosecution for personal use. However, state and federal laws are still in effect, and individuals can be prosecuted for possession and distribution.
A common mistake is to assume that local decriminalization measures provide complete legal protection. State and federal laws still apply, and individuals can face legal consequences, especially for distribution or possession in jurisdictions that have not decriminalized psilocybin.
Local Exceptions
None identified. State law applies uniformly across Massachusetts. Local ordinances may still vary — check with your city or county government for any additional rules.
Bottom Line
Psilocybin Therapy is illegal in Massachusetts. This activity can result in criminal charges. Do not assume enforcement is lax — penalties are real. Consult a licensed attorney if you have specific questions.
