Quick answer: Yes. Missouri lists psilocybin and psilocyn as Schedule I hallucinogens in section 195.017 of the Revised Statutes of Missouri, and neither that section nor the drug definitions in section 195.010 mention spores, mycelium or mushrooms. That leaves mushroom spores legal in Missouri to buy, own and ship for microscopy, taxonomy and educational use, because spores contain neither compound.
What is not legal is germinating them. Missouri’s definition of “production” includes “planting, cultivation, growing, or harvesting,” and knowingly growing a controlled substance is a class C felony under section 579.055. Missouri lawmakers have filed psilocybin research and therapy bills every year since 2023, and none has become law.

What Missouri law says (and doesn’t say)
Missouri’s drug schedules are in section 195.017 of the Revised Statutes of Missouri (RSMo). The hallucinogen list in Schedule I controls “any material, compound, mixture or preparation which contains any quantity of the following hallucinogenic substances,” and it includes “(ll) Psilocybin” and “(mm) Psilocyn.” That is where the mushroom compounds live in Missouri law.
Section 195.017 does not mention spores, mycelium or mushrooms. The definitions in section 195.010, which set out what counts as manufacturing, production and drug paraphernalia, do not mention them either. Missouri law controls the chemicals, and a spore does not contain them.
Why spores are legal 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. In a letter dated January 2, 2024, the DEA’s Drug & Chemical Evaluation Section confirmed that mushroom spores that do not contain psilocybin or psilocin are not controlled, and it 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.
Section 195.010 defines “manufacture” as “the production, preparation, propagation, compounding or processing” of a controlled substance, and it says “production” includes “the manufacture, planting, cultivation, growing, or harvesting” of one. The line in Missouri is the same as the federal line: the spore is legal, and the germinated material is not.
Penalties for the mushrooms themselves
Missouri’s drug crimes are in chapter 579, and the sentence ranges for each class of offense are in chapter 558.
- Possession (RSMo 579.015): possessing any controlled substance other than 35 grams or less of marijuana is a class D felony, punishable by up to seven years in prison and a fine of up to $10,000.
- Manufacture (RSMo 579.055): knowingly manufacturing, producing or growing a controlled substance, attempting to, or possessing one with intent to do so is a class C felony, punishable by three to ten years in prison. It is a class B felony within 2,000 feet of a school or college. Growing mushrooms from spores is charged under this section.
The paraphernalia law: RSMo 579.074
Missouri’s paraphernalia law is the provision that matters most to a spore buyer, because it turns on intended use.
- The definition in section 195.010 covers equipment “used, intended for use, or designed for use, in planting, propagating, cultivating, growing, harvesting, manufacturing” a controlled substance. It specifically includes “kits used, intended for use, or designed for use in planting, propagating, cultivating, growing or harvesting of any species of plant which is a controlled substance or from which a controlled substance can be derived.”
- Possession (RSMo 579.074): knowingly using or possessing paraphernalia with intent to use it to grow or manufacture a controlled substance is a class D misdemeanor, which carries a fine of up to $500. It is a class A misdemeanor, punishable by up to one year in jail, for someone with a prior drug conviction.
- Manufacture (RSMo 579.076): manufacturing paraphernalia with intent to deliver it, knowing it will be used with a controlled substance, is a class A misdemeanor, or a class E felony if it is done for commercial purposes.
- How courts decide: section 195.010 tells courts to consider, among other factors, “statements by an owner or by anyone in control of the object concerning its use,” “instructions, oral or written, provided with the object concerning its use,” and “the existence and scope of legitimate uses for the object in the community.” There is no exemption for research or microscopy, so the question is intent and context.
A spore syringe bought for study is not paraphernalia. The same syringe next to cultivation equipment, with a stated plan to use it that way, 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.
Kansas City, St. Louis, Columbia: any local decriminalization?
No Missouri city council or county has passed a psilocybin decriminalization or deprioritization measure. It would not matter for spores if one had, because spores are already legal statewide. Minneapolis, by contrast, made psilocybin the lowest police priority by mayoral executive order in 2023, as our Minnesota guide explains.
Psilocybin research and therapy bills, 2023–2026
Missouri lawmakers have filed a psilocybin research or therapy bill in every session since 2023, and each one has failed.
2023: HB 1154. Rep. Dan Houx’s bill would have required the Department of Health and Senior Services to fund a $2 million study of psilocybin therapy for depression, PTSD, substance use disorders and end-of-life care, subject to appropriation, in partnership with a Missouri university hospital or VA medical facility. The House gave it initial approval in March 2023, but it never received the final House vote it needed to go to the Senate.
2024: HB 1830 and SB 768. These bills would have allowed Missouri veterans 21 and older with conditions such as PTSD to use psilocybin while enrolled in approved studies. HB 1830, sponsored by Rep. Aaron McMullen, and SB 768 each cleared a committee, and neither received a final vote in its chamber.
2025: SB 90. Sen. Stephen Webber’s bill would have allowed veterans and other patients with qualifying conditions to use psilocybin while enrolled in approved studies, and it would have put $3 million toward psilocybin research. The Senate Families, Seniors and Health Committee approved it on March 12, 2025, but it never reached a Senate floor vote. A House version, HB 951, did not advance.
2026: HB 1717. Rep. Richard West’s bill, combined with HB 1643, would have required the state to study psilocybin and other alternative therapies and allowed veterans and first responders enrolled in the study to possess psilocybin given by a facilitator. It called for $2 million in research grants through the Department of Mental Health, subject to appropriation, and it also covered ibogaine. The House passed it 137–11 on April 2, 2026, which was the first time the House had sent one of these psilocybin bills to the Senate. A Senate committee approved it, but it was placed on the Senate’s informal calendar on May 7 and did not get a final vote before the session ended on May 15, 2026.
As of September 2026, Missouri has no psilocybin therapy law and no state-funded psilocybin research program. None of these bills would have changed the status of spores, which are already legal.
Buying spores in Missouri
- It is legal to buy and own Psilocybe cubensis spores in Missouri 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 Missouri.
- Use spores for study only. Missouri’s paraphernalia law is intent-based, and its manufacturing law names growing. Spores for microscopy are a legal hobby; anything that points toward cultivation is where the law starts.
