Psilocybin is still illegal statewide in Massachusetts in 2026, though eight cities have deprioritized enforcement and a supervised psychedelic-therapy pilot is advancing in the legislature.
Massachusetts sits in an in-between place on psilocybin in 2026: still illegal statewide, but closer to limited therapeutic access than ever before. Voters said no to full legalization in November 2024, rejecting Question 4 by a wide margin, and psilocybin remains a Class C controlled substance across the Commonwealth. At the same time, eight municipalities — Somerville, Cambridge, Northampton, Easthampton, Amherst, Salem, Provincetown, and Medford — have formally asked police to treat personal use of natural psychedelics as a lowest enforcement priority. The real movement is now on Beacon Hill. In December 2025, a legislative committee approved psilocybin bills for the first time in state history, and in July 2026 the House passed a five-year pilot program that would allow up to three licensed clinics to offer supervised, on-site psilocybin treatment. Neither track is law yet: until the Senate and Governor Healey act, there is no legal way to buy or use psilocybin in Massachusetts — only spores for microscopy, amanita muscaria, and functional mushrooms can be bought without running into drug law.
Possession
Possessing any amount of psilocybin is a crime everywhere in Massachusetts — it is a Class C controlled substance under state law. Eight municipalities have passed resolutions making enforcement against personal use of plant- and fungi-based psychedelics among the lowest police priorities, but those resolutions do not change state law or protect anyone from arrest.
Cultivation
Growing psilocybin mushrooms is treated as manufacturing a controlled substance under Massachusetts law and remains a felony statewide, even in cities with deprioritization resolutions.
Retail / purchase
No purchase of psilocybin is legal anywhere in Massachusetts in any form — there are no licensed dispensaries, service centers, or therapy programs. Mushroom-related purchases that are not barred by drug law are limited to psilocybin spores sold for microscopy, amanita muscaria products (not a controlled substance, but not FDA-approved for food), and functional (non-psychoactive) mushrooms.

Spores
Psilocybin spores are legal to buy and possess in Massachusetts for microscopy and research purposes, because the spores themselves contain no psilocybin — state law bans the compound, not the spore. Only California, Georgia, Idaho, and Florida ban psilocybin spores outright, and Massachusetts is not among them. The exemption is narrow: germinating spores into mushrooms is illegal cultivation, and selling or possessing spores with the intent that they be grown into psilocybin mushrooms can still be charged under state drug law.
Amanita muscaria
Amanita muscaria is a different mushroom from psilocybin species and is not a controlled substance federally or under Massachusetts law, so it is sold openly in the state. Its regulatory footing is weaker than 'legal' suggests: in December 2024 the FDA determined that Amanita muscaria and its constituents muscimol and ibotenic acid are not approved and not generally recognized as safe for use in conventional food, and the agency is still evaluating their use in dietary supplements; some state regulators, including Florida's, have treated amanita edibles as adulterated products. Louisiana is the one state with an outright ban (Act 159, with an exception for ornamental and decorative use). Because the category is unapproved rather than regulated, potency, labeling, and dosing vary widely between products, and amanita has its own toxicity profile — approach with caution.
Recent changes
In November 2024, Massachusetts voters rejected Question 4, the Natural Psychedelic Substances Act, which would have legalized regulated therapeutic access and home cultivation of five natural psychedelics (psilocybin, psilocin, DMT, mescaline, and ibogaine); the final tally was roughly 56.9% no to 43.1% yes. Medford had become the eighth city to adopt a deprioritization resolution in February 2024, and no ninth municipality has followed since. Momentum shifted to the legislature: on December 20, 2025, the Joint Committee on Public Health voted 10-1 (one abstention) to advance H.2532 (a psilocybin-therapy and clinical-research framework) and H.2506 (psilocybin access for veterans, law enforcement, first responders, and qualifying patients with conditions such as severe depression or cancer) — the first time a Massachusetts committee approved a psilocybin legalization measure. On July 9, 2026, the House unanimously adopted an amendment to its $561 million economic development bond bill, H.5562 (which then passed the chamber 148-2), creating a five-year pilot allowing the Department of Public Health to permit up to three licensed mental-health clinics to administer supervised, on-site treatment with naturally occurring psychedelic materials; participating clinics cannot be affiliated with cannabis, pharmaceutical, or psychedelic drug-development companies, and the amendment separately directs the state to help facilitate federally authorized research on ibogaine, 5-MeO-DMT, and MDMA-assisted therapy. As of late July 2026 the pilot still needs Senate approval and Governor Healey's signature, so nothing in it is in effect yet.
First-offense possession of a Class C substance like psilocybin carries up to one year in a house of correction and a fine of up to $1,000 under M.G.L. c. 94C, § 34. In practice many first-time defendants receive a lesser disposition such as pretrial probation or a continuance without a finding that ends in dismissal, but that is a discretionary outcome negotiated case by case — the statute's automatic probation-and-dismissal provision applies to Class D (marijuana) offenses, not Class C. Cultivation or sale is charged as manufacturing or distributing a Class C substance under § 32C, a felony carrying substantially heavier exposure. This is general information, not legal advice.
Legal options for Massachusetts residents
The nearest genuinely legal psilocybin access for Massachusetts residents is travel to Oregon's licensed psilocybin service centers or Colorado's licensed healing centers, both operating under state-regulated supervised-session programs. Within Massachusetts, spores for microscopy, amanita muscaria products, and functional mushrooms are the only mushroom purchases that do not run into drug law.

FAQ
Are shrooms legal in Massachusetts?
No. Psilocybin mushrooms are illegal to possess, grow, or sell anywhere in Massachusetts in 2026. Voters rejected a legalization ballot measure (Question 4) in November 2024, and while eight cities — including Somerville, Cambridge, and Salem — have told police to make personal-use enforcement a lowest priority, that is not the same as legal.
Are magic mushrooms decriminalized in Boston?
No. Boston has not passed a deprioritization resolution. Eight other Massachusetts municipalities have — Somerville, Cambridge, Northampton, Easthampton, Amherst, Salem, Provincetown, and Medford — but even in those cities psilocybin remains illegal under state law; police have simply been asked to treat personal use as a low enforcement priority.
Did Massachusetts legalize psychedelics in 2024?
No. Question 4, the Natural Psychedelic Substances Act, was defeated in November 2024 by about 56.9% to 43.1%. It would have created state-regulated therapy centers and allowed limited home cultivation of psilocybin, psilocin, DMT, mescaline, and ibogaine. Under Article 48 of the Massachusetts Constitution, an initiative substantially the same as one submitted to voters at either of the two preceding biennial state elections cannot go back on the ballot, which keeps a repeat measure off the 2026 and 2028 ballots — so reform efforts have moved to the legislature.
Can you buy psilocybin legally anywhere in Massachusetts?
No. There is no legal retail or therapeutic market for psilocybin in Massachusetts, and anything sold in the state is unregulated and illegal. What can be bought without breaking drug law is limited to psilocybin spores for microscopy, amanita muscaria products (unscheduled, though the FDA has not approved them for food), and functional mushrooms. Residents seeking legal psilocybin experiences must travel to Oregon's licensed psilocybin service centers or Colorado's licensed healing centers and go through those states' regulated programs.
Will Massachusetts legalize psilocybin therapy?
Possibly in limited form. On July 9, 2026 the Massachusetts House passed a five-year pilot program (the pilot amendment was adopted unanimously; the underlying economic development bill passed 148-2) that would let the Department of Public Health permit up to three licensed mental-health clinics to offer supervised, on-site treatment with naturally occurring psychedelic materials; the bill also directs the state to facilitate federally authorized research on ibogaine, 5-MeO-DMT, and MDMA. It still needs Senate approval and Governor Healey's signature, and separate bills covering veterans, law enforcement, first responders, and qualifying patients advanced out of the Joint Committee on Public Health in December 2025. Nothing in either track is law yet, so psilocybin remains illegal in Massachusetts today.
