What Massachusetts law says (and doesn’t say)

Massachusetts sorts controlled substances into Classes A through E instead of numbered schedules. Chapter 94C, section 31 sets out the classes, and Class C lists “Psilocybin” and “Psilocyn” among its hallucinogenic substances. It controls “any material, compound, mixture, or preparation, which contains any quantity of” them.

That is where the mushroom compounds live in Massachusetts law. Section 31 does not mention spores. Section 1, which holds the definitions for the chapter, including “manufacture” and “drug paraphernalia,” does not mention them either. Massachusetts has never written spores, mycelium or mushrooms into its statutes.

Why spores are legal when the mushrooms are not

A spore contains no psilocybin and no psilocyn. Class C reaches material that “contains any quantity” of a listed substance; a spore contains none, so it is not a Class C material. The federal government reached the same conclusion. On January 2, 2024, the DEA’s Drug & Chemical Evaluation Section confirmed in writing that mushroom spores that do not contain psilocybin or psilocin are not controlled. The letter added that “if at any time the material contains a controlled substance such as psilocybin or psilocin (for example, upon germination), the material would be considered a controlled substance under the CSA.” Our state-by-state guide covers the federal letter in detail.

Massachusetts defines “manufacture” in section 1 as “the production, preparation, propagation, compounding, conversion or processing of a controlled substance.” Germination is propagation. The line in Massachusetts is the same as the federal line: the spore is legal, and the germinated material is not.

Penalties for the mushrooms themselves

Psilocybin is a Class C substance, so the Class C penalties apply.

• Possession (M.G.L. c. 94C, § 34): for a first offense, up to one year in jail, a fine of up to $1,000, or both.
• Manufacture, distribution or possession with intent (M.G.L. c. 94C, § 32B): up to five years in state prison or up to two and a half years in a jail or house of correction, and a fine of $500 to $5,000. The penalties rise for a second offense. Because “manufacture” includes propagation, germinating spores falls under this section.

The paraphernalia law: M.G.L. c. 94C, § 32I

The paraphernalia law is the Massachusetts provision that matters most to a spore buyer, because it turns on intended use.

• The definition (section 1) covers items “primarily intended or designed for use in planting, propagating, cultivating, growing, harvesting, manufacturing” a controlled substance, including kits for growing “any species of plant which is a controlled substance or from which a controlled substance can be derived.” The factors a court weighs include “the existence and scope of legitimate uses for the object in the community.”
• The offense (section 32I(a)) is to “sell, possess or purchase with intent to sell, or manufacture with intent to sell” paraphernalia, “knowing, or under circumstances where one reasonably should know,” that it will be used to plant, propagate, cultivate or grow a controlled substance. The penalty is up to two years in jail, a fine of up to $5,000, or both.
• Selling to a person under 18 (section 32I(b)) carries three to five years in state prison, a fine of $1,000 to $5,000, or both.

The text of section 32I is written around selling. Some Massachusetts defense lawyers describe possession of paraphernalia for personal use as a crime and others do not, so the sources disagree on that point. Either way, the law turns on cultivation intent. A spore syringe bought for study is not paraphernalia. This is why we sell spores for microscopy only, do not provide cultivation instructions, and cancel orders from customers who tell us they intend to cultivate.

Somerville, Cambridge, Salem: what local decriminalization means

At least eight Massachusetts communities have passed local psychedelic measures. They are listed below in the order they acted.

• Somerville: city council resolution, unanimous, January 14, 2021. It made the arrest of adults for using or possessing controlled substances “amongst the lowest law enforcement priority” for the city.
• Cambridge: city council policy order, February 2021, passed 8–1.
• Northampton: city council resolution, unanimous, April 2021.
• Easthampton: city council resolution, October 2021.
• Amherst: a town council resolution supporting the decriminalization of plant medicines, July 18, 2022. News reports differ on whether it changes local police priorities or only calls for state action.
• Salem: city council resolution, unanimous, May 2023. It covers psilocybin mushrooms only.
• Provincetown: select board resolution, December 2023, passed 3–1 with one abstention.
• Medford: city council resolution, February 2024.

Every one of these is a “lowest law enforcement priority” resolution or a statement of support. None changes state law, and none affects spores, because spores are legal statewide with or without them. If you read a page claiming that Somerville or Cambridge “legalized” mushrooms, it is wrong.

Question 4: the 2024 ballot measure voters rejected

On November 5, 2024, Massachusetts voted on Question 4, “Limited Legalization and Regulation of Certain Natural Psychedelic Substances.” It would have let adults 21 and older possess set amounts of psilocybin, psilocyn, DMT, mescaline and ibogaine, grow them at home in a 12-foot by 12-foot area, and use them at licensed locations with a licensed facilitator. A new Natural Psychedelic Substances Commission would have regulated the system.

Voters rejected it. According to the official results, 1,902,513 voters (56.8 percent) voted no and 1,444,797 (43.2 percent) voted yes. Its defeat did not change anything about spores.

Psilocybin bills in the 2025–2026 session

After Question 4 failed, legislators turned to narrower, medical proposals. As of September 2026, none has become law.

• H.2203, filed by Representative Marjorie Decker, would create a psilocybin pilot program run by the Department of Public Health for adults with PTSD and certain other conditions. H.4200, filed by Representative James O’Day, would allow a pilot using psychedelics in licensed treatment facilities. Both were reported favorably by the Joint Committee on Mental Health, Substance Use and Recovery in March 2026 and by the Joint Committee on Health Care Financing in July 2026. Both are now in the House Committee on Ways and Means.
• H.2506 (decriminalizing psilocybin as a treatment for PTSD and certain other conditions) and H.2532 (therapeutic psilocybin treatment centers) were combined by the Joint Committee on Public Health into a new draft, H.4986, on January 28, 2026. H.4986 is in the Joint Committee on Health Care Financing, which has until December 31, 2026 to report on it.
• The HERO Act (Chapter 178 of the Acts of 2024), signed August 8, 2024, created a working group to study psychedelic therapy for veterans. It did not change any drug law.

None of these bills mentions spores.

Buying spores in Massachusetts

• It is legal to buy and own Psilocybe cubensis spores in Massachusetts for microscopy, taxonomy and educational use.
• Ordering online is legal. Federal mail rules bar controlled substances and paraphernalia, and spores are neither. We ship to Massachusetts.
• Use spores for study only. Massachusetts defines manufacturing to include propagation, and its paraphernalia statute turns on what an item is intended for. Spores for microscopy are a legal hobby, and anything that points toward cultivation is where the law starts.

Our guides for New York and New Jersey explain the law in nearby states.
