Quick answer: Yes, mushroom spores are legal in Rhode Island. Since February 1, 2025, Rhode Island has controlled psilocybin and psilocyn by adopting the federal Schedule I list (21 C.F.R. § 1308.11) through R.I. Gen. Laws § 21-28-2.01, instead of the old state schedule in section 21-28-2.08. Neither the federal rule nor Rhode Island’s drug law mentions spores, mycelium or mushrooms. That makes mushroom spores legal in Rhode Island to buy, own and ship for microscopy, taxonomy and educational use.
What is not legal is germinating them. Rhode Island defines “manufacture” to include “propagation” and “cultivation,” and manufacturing a Schedule I substance carries up to 30 years in prison. Bills to legalize psilocybin have been filed every year since 2023, and none has become law.

What Rhode Island law says (and doesn’t say)
Rhode Island’s drug law is the Uniform Controlled Substances Act, Chapter 21-28 of the General Laws. For decades its schedules were written out in section 21-28-2.08. In 2024 the General Assembly repealed that section (P.L. 2024, ch. 390 and ch. 391), effective February 1, 2025. If you see section 21-28-2.08 cited as Rhode Island’s Schedule I, that citation is out of date.
Today, section 21-28-2.01 says that “the director of the department of health shall control all substances enumerated in the most current version of Title 21 of the Code of Federal Regulations.” The federal Schedule I list, 21 C.F.R. § 1308.11(d), controls “any material, compound, mixture, or preparation, which contains any quantity” of the listed hallucinogens, and it lists “(29) Psilocybin” and “(30) Psilocyn.” The Rhode Island Department of Health’s own controlled substance listing says the department “recognizes the current version of Title 21 of the Code of Federal Regulations (CFR) as the most updated list of controlled substances in Rhode Island.”
That is where the mushroom compounds live in Rhode Island law. The federal rule does not mention spores. Rhode Island’s definitions section (21-28-1.02) and its paraphernalia chapter (21-28.5) do not mention spores, mycelium or mushrooms either.
Why are mushroom spores legal in Rhode Island when the mushrooms are not?
A spore contains no psilocybin and no psilocyn. Schedule I reaches material that “contains any quantity” of a listed substance; a spore contains none, so it is not a Schedule I 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 adds 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.
Rhode Island’s definition of “manufacture” in section 21-28-1.02 begins “the production, preparation, propagation, cultivation, compounding, or processing of a drug or other substance.” The line in Rhode Island is the same as the federal line: the spore is legal, and the germinated material is not.
Penalties for psilocybin mushrooms in Rhode Island
Section 21-28-4.01 sets the penalties. Rhode Island measures possession by the weight of “a mixture or substance containing a detectable amount of a controlled substance.”
- Possession of 10 grams or less (§ 21-28-4.01(c)(2)(i)): a misdemeanor, punishable by up to 2 years in prison or a fine of up to $500.
- Possession of more than 10 grams but less than one ounce (§ 21-28-4.01(c)(2)(ii)): a felony, punishable by up to 3 years in prison or a fine of up to $5,000.
- Manufacture, delivery or possession with intent (§ 21-28-4.01(a)(4)(i)): for a Schedule I substance, up to 30 years in prison or a fine of $3,000 to $100,000. Because “manufacture” includes propagation and cultivation, growing mushrooms from spores is charged here.
The paraphernalia law: sale and delivery only
Rhode Island’s paraphernalia chapter (21-28.5) is unusual, and it is favorable to a hobbyist.
- The definition in section 21-28.5-1 covers equipment “intended for use or designed for use in planting, propagating, cultivating, growing, harvesting” a controlled substance. It names kits for “planting, propagating, cultivating, growing, or harvesting of any species of plant which is a controlled substance.”
- There is no simple-possession offense in the chapter. The only offenses are delivering or selling paraphernalia, possessing it with intent to deliver or sell, or manufacturing it for delivery or sale, “knowing that it will be used to plant, propagate, cultivate, grow, harvest” or use a controlled substance (§ 21-28.5-2). That carries up to 2 years in prison, a fine of up to $5,000, or both. Delivering paraphernalia to a person under 18 carries up to 5 years (§ 21-28.5-3).
- How courts decide: the definition lists factors, including statements by the owner about the object’s use, instructions provided with it, advertising, and whether legitimate uses for the object exist in the community.
A spore syringe bought for study is not paraphernalia. The same syringe sold or handed over with a stated plan to grow mushrooms can be. 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.
Providence, Warwick, Cranston: any local decriminalization?
No. No Rhode Island city or town has passed a psilocybin decriminalization or deprioritization measure. It would not matter for spores if one had, because spores are already legal statewide.
The 2023–2026 psilocybin bills
Rhode Island lawmakers have filed a psilocybin legalization bill in every session since 2023. One passed the House, and none has become law.
- 2023: H 5923 and S 0806. Rep. Brandon Potter and Sen. Meghan Kallman introduced matching bills on March 1, 2023. They would have allowed a person to possess less than one ounce of psilocybin and to cultivate it at home for personal use, and they told the Department of Health to prepare rules for therapeutic use if the FDA reschedules psilocybin. The House Judiciary Committee added a sunset date of July 1, 2025. The House passed the amended bill on June 12, 2023. In the Senate, the companion bill was held in committee for further study, and neither bill received a Senate vote.
- 2024: H 7047. Rep. Potter filed a similar bill on January 5, 2024, with a sunset date of July 1, 2026. After a hearing, the House Judiciary Committee held it for further study, and it did not advance.
- 2025: H 5186. A new version with a sunset date of July 1, 2027 was introduced on January 24, 2025. The House Judiciary Committee held it for further study on February 11, 2025, and it did not advance.
- 2026: H 7756. The latest version was introduced on February 12, 2026. It would have added a new section 21-28-2.11 exempting less than one ounce of psilocybin and home cultivation for personal use, from July 1, 2026 to July 1, 2028. It was withdrawn at the sponsors’ request on April 9, 2026.
As of September 2026, no psilocybin law has been enacted in Rhode Island, and section 21-28-2.11 does not exist. Psilocybin mushrooms remain illegal. None of this affects spores, which were legal before these bills and remain legal now.
Buying spores in Rhode Island
- It is legal to buy and own Psilocybe cubensis spores in Rhode Island for microscopy, taxonomy and educational use.
- Ordering online is legal. Federal mail rules bar controlled substances and paraphernalia, and spores are neither. We ship spore syringes to Rhode Island.
- Use spores for study only. Rhode Island’s definition of “manufacture” names propagation and cultivation, and its paraphernalia law turns on what a seller knows about intended use. Studying spores is a legal hobby, and anything that points toward cultivation is where the law starts.

Are psilocybin mushrooms legal in Rhode Island?
No. Possessing 10 grams or less is a misdemeanor, and possessing more is a felony. Growing them is manufacturing a Schedule I substance, which carries up to 30 years in prison.
