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.

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.
