No. Massachusetts voters rejected Question 4 (natural psychedelic substances) in November 2024, 57–43. Psilocybin is Schedule I under MGL c.94C §31. Seven cities have deprioritization resolutions (Somerville, Cambridge, Northampton, Easthampton, Salem, Amherst, Provincetown) but these are not legal protections.
No. Massachusetts voters rejected Question 4 — the Natural Psychedelic Substances Initiative — in November 2024 by a 57-43 margin. Psilocybin remains Schedule I under Massachusetts General Laws c.94C §31. Seven cities (Somerville, Cambridge, Northampton, Easthampton, Salem, Amherst, Provincetown) have passed deprioritization resolutions, but these affect local police priorities only and do not make psilocybin legal.
Yes. Question 4 on the November 2024 ballot would have decriminalized personal use and possession of psilocybin, DMT, mescaline, and ibogaine for adults and created a regulatory framework for therapeutic access. Voters rejected it 57% to 43%.
Not legally. Cambridge has a city deprioritization resolution, but Boston does not. Massachusetts state law applies in both cities — psilocybin is Schedule I. Cambridge's resolution directs local police to treat entheogen enforcement as lowest priority; it is not a legal protection against state or federal charges.
Yes. A new ballot initiative could be filed for a future election cycle. Advocacy organizations are analyzing what changes to the ballot language might improve passage. A legislative approach (through the state legislature rather than ballot initiative) is also possible.
Possession of psilocybin in Massachusetts is a criminal offense. Under Massachusetts General Laws c.94C §34, possession of a Class C controlled substance — which includes psilocybin — is punishable by up to one year in jail and a fine of up to $1,000 for a first offense. Subsequent offenses carry up to two years. Distribution or trafficking under MGL c.94C §32B carries substantially heavier penalties. The seven cities with deprioritization resolutions do not provide legal protection against state or federal charges.
Yes. Amanita muscaria (the red-and-white spotted mushroom) is not a controlled substance under Massachusetts General Laws c.94C or federal law. It contains muscimol, not psilocybin, and is a legally distinct product. Amanita muscaria gummies and extracts are sold legally in Massachusetts. However, Amanita muscaria is not psilocybin and does not produce the same clinical or psychedelic effects.
