What Oregon law says (and doesn’t say)

Oregon does not print its own list of hallucinogens in the statute books. Under ORS 475.005, a “controlled substance” is a drug classified in Schedules I through V of the federal Controlled Substances Act, “as modified under ORS 475.035,” which lets the State Board of Pharmacy change the schedules by rule. The Board’s Schedule I rule, OAR 855-080-0021, adopts the substances “listed in 21 CFR 1308.11.” That federal list includes psilocybin and psilocyn among the hallucinogens and controls “any material, compound, mixture, or preparation, which contains any quantity” of them.

The same Oregon definition contains an important exception. Psilocybin and psilocin are not controlled substances “only if and to the extent that” a person manufactures, delivers or possesses them in accordance with ORS 475A.210 to 475A.722, the psilocybin services law, and its rules. Outside that program, they are ordinary Schedule I drugs.

None of these texts mentions spores. ORS chapter 475 does not mention spores or mycelium in its definitions, offenses or paraphernalia sections, and the Board of Pharmacy rule does not either. Chapter 475A, which runs the licensed program, defines “psilocybin products” as psilocybin-producing fungi and mixtures containing a detectable amount of psilocybin, and it never mentions spores.

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: 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 also said 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.

Oregon’s definition of “manufacture” in ORS 475.005 is “the production, preparation, propagation, compounding, conversion or processing of a controlled substance.” Propagation is germination. The line in Oregon is the same as the federal line: the spore is legal, and the germinated material is not, unless a licensed manufacturer grows it inside the state program.

Oregon’s psilocybin program: what Measure 109 covers

Oregon voters approved Measure 109 in November 2020. It is now codified as ORS chapter 475A, the Oregon Psilocybin Services Act, and it directs the Oregon Health Authority to license and regulate the manufacturing, delivery and sale of psilocybin products and the provision of psilocybin services. The Health Authority’s Oregon Psilocybin Services section began accepting license applications on January 2, 2023, and service centers began opening to clients in 2023.

• Who is licensed: the law has four license types: psilocybin product manufacturers, service center operators, facilitators and testing laboratories.
• How clients take part: a client consumes psilocybin during an “administration session” at a licensed service center, under the supervision of a licensed facilitator (ORS 475A.498). The Health Authority may not require a client to have any particular medical condition (ORS 475A.235), so no prescription is needed. Products cannot be bought and taken home.
• The legal protection: ORS 475A.275 says that manufacture, delivery or possession by a licensee in compliance with the law and its rules “does not constitute a criminal or civil offense under the laws of this state.”

The program does not cover anyone outside it. There is no home-grow provision, and the exception in ORS 475.005 applies only “to the extent” someone follows the program’s rules. A person without a manufacturer license who grows psilocybin mushrooms is manufacturing a Schedule I substance under ordinary Oregon drug law.

The program also does not change anything about spores, because spores were never controlled in the first place. You do not need a license to buy or own spores for microscopy, and the program’s licenses are not a route to growing at home.

Penalties for the mushrooms themselves

Outside the licensed program, psilocybin is a Schedule I substance, and the penalties in ORS 475.752 apply.

• Manufacture or delivery (ORS 475.752(1)(a)): a Class A felony for a Schedule I substance. Because “manufacture” includes propagation, growing psilocybin mushrooms outside the program falls here.
• Possession of a small amount (ORS 475.752(3)(a)): a drug enforcement misdemeanor since September 1, 2024. Under ORS 475.896, the court can impose probation of up to 18 months, and jail of up to 180 days.
• Larger amounts (ORS 475.752(7)): possession of 12 grams or more of a mixture or substance containing psilocybin or psilocin is a Class A misdemeanor. Possession that is a commercial drug offense, or that involves a substantial quantity, is a Class B felony.

These rules are recent. Measure 110, which voters also passed in November 2020, turned possession of small amounts of drugs into a Class E violation with a maximum fine of $100, effective February 1, 2021. The Legislature reversed that in 2024 with House Bill 4002, which made possession a crime again starting September 1, 2024. Some news summaries describe the new offense as a Class C misdemeanor, but the statute itself calls it a drug enforcement misdemeanor, and that is the term used above.

The paraphernalia law: ORS 475.525

Oregon’s paraphernalia law covers selling and supplying paraphernalia, not owning it, and its penalty is civil rather than criminal.

• What it prohibits: selling, delivering, or possessing or manufacturing with intent to sell or deliver drug paraphernalia, “knowing that it will be used to unlawfully plant, propagate, cultivate, grow, harvest” or otherwise produce or use a controlled substance.
• The definition includes “kits marketed for use or designed for use in unlawfully planting, propagating, cultivating, growing or harvesting” a plant from which a controlled substance can be derived.
• The penalty: a civil penalty of at least $2,000 and not more than $10,000 (ORS 475.565).
• Simple possession of paraphernalia for personal use is not an offense under this section.
• How courts decide: the statute lists factors, including instructions provided with the object, descriptive material packaged with it, and advertising about its use.

A spore syringe bought for study is not paraphernalia. The law turns on knowledge and marketing, which 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.

Local votes on psilocybin businesses

In Oregon, the local votes that matter have been about whether to allow licensed psilocybin businesses at all. ORS 475A.718 lets a city or county refer a ban on psilocybin businesses to its voters. In November 2022, voters in 25 of Oregon’s 36 counties voted against allowing psilocybin businesses, and dozens of cities did the same.

These votes only decide where licensed service centers and manufacturers can operate. They do not change the statewide possession and manufacturing rules, and they have nothing to do with spores, which are legal everywhere in Oregon. For the law just north of Oregon, see our Washington guide.

Recent laws and bills in Oregon

• House Bill 4002 (2024): ended Measure 110’s decriminalization of possession and created the drug enforcement misdemeanor, effective September 1, 2024 (Oregon Laws 2024, chapter 70).
• House Bill 2387 (2025): lets doctors, therapists and other licensed health professionals provide psilocybin services if they also hold a facilitator license, and adds new product labeling requirements. It became law as Oregon Laws 2025, chapter 147.
• House Bill 4040 (2026): a broader health care bill that, among other things, extends the same dual-licensing approach to occupational therapists and physical therapists. It became law as Oregon Laws 2026, chapter 109, and the Health Authority proposed rules to carry it out in August 2026.

All of these laws adjust who can provide psilocybin inside the licensed program. None of them adds spores to Oregon law or allows personal cultivation.

Buying spores in Oregon

• It is legal to buy and own Psilocybe cubensis spores in Oregon for microscopy, taxonomy and educational use.
• Ordering online is legal. Federal mail rules bar controlled substances and paraphernalia; spores are neither. We ship to Oregon.
• Use spores for study only. Oregon’s program licenses manufacturers, and growing outside it is manufacturing a Schedule I substance. Spores for microscopy are a legal hobby; anything that points toward cultivation is where the law starts.

Frequently asked questions

Are mushroom spores legal in Oregon?

Yes. Oregon’s Schedule I list covers psilocybin and psilocyn, and spores contain neither. No Oregon statute or rule mentions spores.

Is it legal to buy mushroom spores in Oregon?

Yes. You can legally buy and own mushroom spores in Oregon for microscopy, taxonomy and educational use.

Is it legal to order mushroom spores online in Oregon?

Yes. There is no Oregon or federal law against mailing spores. The mail rules cover controlled substances and paraphernalia, and spores are neither.

Are Psilocybe cubensis spores legal in Oregon?

Yes. The species does not change the analysis, because no Psilocybe spore contains a Schedule I substance.

Are psilocybin mushrooms legal in Oregon?

Psilocybin is legal only inside the licensed program, where adults can take it at a licensed service center under a licensed facilitator’s supervision. Outside the program, possession is a drug enforcement misdemeanor or worse, and manufacturing is a Class A felony.

Can I grow psilocybin mushrooms at home under Measure 109?

No. Measure 109 licenses manufacturers and service centers, and it has no home-grow provision. Growing without a manufacturer license is manufacturing a Schedule I substance.

Are mushroom grow kits legal in Oregon?

A kit for culinary species is legal. Selling a kit knowing it will be used to grow a controlled substance violates ORS 475.525, and such a kit is also paraphernalia under federal law. We do not sell cultivation kits or supplies.

Do you ship spore syringes to Oregon?

Yes, to every Oregon address. The only states we exclude are California, Florida, Georgia and Idaho. If you live nearby, see our guides for California and Idaho, two of the states where spores are restricted, or read about New Mexico’s medical psilocybin program.
