Psilocybin and Psychedelics in Massachusetts: Decriminalized
This page tracks the current legal status of psilocybin, psychedelics, and entheogens in Massachusetts. Status is updated from our legislation sync, with citations to the underlying bills and policy decisions.
Massachusetts voters rejected Question 4 in November 2024, which would have decriminalized psychedelic substances statewide and established a regulated marketplace for adults 21+. Multiple cities (Cambridge, Somerville, Northampton, Easthampton) maintain local decriminalization ordinances. Advocates are regrouping with a potential revised approach for 2028 that focuses more narrowly on therapeutic access rather than broad decriminalization.
