What Arizona law says (and doesn’t say)

Arizona’s criminal code does not use the phrase “Schedule I.” Instead, A.R.S. § 13-3401(6) defines “dangerous drug,” and subdivision (a) controls “any material, compound, mixture or preparation that contains any quantity of” a long list of hallucinogens, among them “(xxxviii) Psilocybin” and “(xxxix) Psilocyn.” (Schedule I also exists in the public-health title, where the Board of Pharmacy adopts the federal schedules by rule, but the criminal penalties run through the “dangerous drug” definition.)

Spores are not mentioned anywhere in section 13-3401, in the dangerous-drug offense section 13-3407, or in the paraphernalia section 13-3415. Arizona has never written spores, mycelium or mushrooms into its drug statutes.

The same section shows the difference. When the legislature wanted to control a whole organism, it said so: marijuana is defined as the plant “whether growing or not, and the seeds of such plant,” and peyote as “any part of a plant of the genus lophophora.” Psilocybin and psilocyn are listed as chemicals only. They say nothing about seeds or spores.

Why spores are legal when the mushrooms are not

A spore contains no psilocybin and no psilocyn. The dangerous-drug definition reaches material that “contains any quantity” of a listed substance; a spore contains none, so it is not a dangerous drug. 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, and that the material becomes controlled once it contains psilocybin or psilocin, for example after germination. Our 50-state guide covers the federal position in detail.

Arizona draws the same line through its definitions. Section 13-3401(17) defines “manufacture” as to “produce, prepare, propagate, compound, mix or process,” and section 13-3401(29) defines “produce” as to “grow, plant, cultivate, harvest, dry, process or prepare for sale.” Germinating a spore is propagation; the spore in the syringe is not.

Penalties for the mushrooms themselves

Arizona’s “threshold amounts,” which remove probation eligibility for sale offenses, list no weight for psilocybin; it falls under a catch-all based on a $1,000 street value.

• Possession or use (§ 13-3407(A)(1)): a Class 4 felony, one to 3.75 years for a first offender. Two rules can lower this penalty. Under § 13-3407(B)(1), a first-time possessor with no prior felony or drug conviction can, on the prosecutor’s motion, have the conviction entered as a Class 1 misdemeanor (up to six months and $2,500). And under § 13-901.01, the 1996 voter initiative known as Proposition 200, a first or second conviction for personal possession must be sentenced to probation and treatment, not prison.
• Manufacture (§ 13-3407(A)(4)): a Class 2 felony, three to 12.5 years for a first offender, and under § 13-3407(F) a person convicted of manufacturing “is not eligible for suspension of sentence, probation, pardon or release” until the sentence is served. Proposition 200’s probation rule expressly excludes manufacturing and production. Because “manufacture” includes propagation, growing is charged here.
• Possessing equipment or chemicals for manufacturing (§ 13-3407(A)(3)): its own Class 3 felony.
• Possession for sale, sale, or transport for sale (§ 13-3407(A)(2), (7)): Class 2 felonies.

Every dangerous-drug felony also carries a fine of at least $1,000 or three times the value of the drugs, up to $150,000.

Arizona’s paraphernalia law: every offense is a felony

Arizona’s paraphernalia statute, § 13-3415, is harsher than most states’ because every offense in it is a Class 6 felony rather than a misdemeanor, and it is the provision that matters most to a spore buyer because it turns on intended use and on what a seller says.

• The definition (§ 13-3415(F)(2)) covers equipment “used, intended for use or designed for use in planting, propagating, cultivating, growing, harvesting… a drug,” where “drug” means any narcotic drug, dangerous drug, marijuana or peyote. Its kit example refers to “any species of plant that is a drug,” and fungi are not plants, but the general definition is not so limited.
• The factors (§ 13-3415(E)) that a court “shall consider” include “instructions, oral or written, provided with the object concerning its use,” “descriptive materials accompanying the object that explain or depict its use,” “national and local advertising concerning its use,” whether the seller “is a legitimate supplier of like or related items to the community,” and “the existence and scope of legitimate uses for the object in the community.”
• Use or possession with intent to use (subsection A), delivery or manufacture for delivery under circumstances where one “reasonably should know” of a drug use (subsection B), and advertising (subsection C) are each a Class 6 felony, four months to two years for a first offender.
• No research or education exemption appears in the section.

A syringe of spores sold for microscopy, with no cultivation instructions and no cultivation supplies, is not paraphernalia under these factors; a spore syringe sold with a grow kit and a description of how to use it would be, and in Arizona that would be a felony for the seller. 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.

The state-funded mushroom trial

Arizona is the first state to fund clinical trials of whole psilocybin mushrooms. The program was created by a 2023 budget law (SB 1726, Laws 2023, Chapter 139, section 6, signed May 11, 2023), which established a Psilocybin Research Advisory Council in the Department of Health Services, set up grants for “whole mushroom psilocybin” phase one, two and three trials, and protected grant recipients and their employees working on the trials (but not the people taking part in them) from prosecution for possessing psilocybin. The $5 million for the grants, for the 2024 fiscal year, came from the 2023 General Appropriations Act (SB 1720).

The grant went to the Scottsdale Research Institute for a PTSD trial in veterans and first responders, which received FDA authorization in 2025. The strain being studied is Jedi Mind Fuck, a Psilocybe cubensis strain whose history is covered in our Jedi Mind Fuck guide. The program and this protection were in section 6 of the 2023 law. That section expired on June 30, 2026, and we found no 2026 law that extended it. Nothing in the program touched spores or private citizens, and the state’s 2025 and 2026 budgets funded ibogaine research rather than more psilocybin work.

Phoenix, Tucson, Flagstaff: any local decriminalization?

No. No Arizona city or county has adopted a psilocybin decriminalization or deprioritization measure.

The bills and the ballot

Arizona has come closer than most states to a psilocybin-services law, and has still passed nothing that affects mushrooms.

• SB 1570 (2024, Senator Shope) would have licensed psilocybin service centers starting in 2026. It passed both chambers (the House on June 14, 2024), and Governor Hobbs vetoed it on June 18, 2024, citing the research council’s view that there was not yet enough evidence for widespread use.
• SB 1555 (2025, Senator Shope) was introduced as an advisory-board bill and passed the Senate 23–4, then was rewritten in the House. The governor signed the rewritten version on June 27, 2025 (Laws 2025, Chapter 231). It applies only to a pharmaceutical “crystalline polymorph psilocybin” product, and only if the FDA approves it and the federal government reschedules it by January 1, 2031. It does not touch mushrooms or spores.
• 2026: no psilocybin bill was introduced.
• The ballot: Arizona allows citizen initiatives for statutes. A “Regulated Access to Psychedelic Mushrooms” initiative was filed but turned in no signatures by the July 2024 deadline. Nothing on psychedelics is on the 2026 ballot.

None of these measures mentions spores, and none would change the status of spores, which are already legal.

Buying spores in Arizona

• It is legal to buy and own Psilocybe cubensis spores in Arizona for microscopy, taxonomy and educational use.
• Ordering online is legal. Federal mail rules bar controlled substances and paraphernalia; spores are neither. We ship to Arizona.
• Use spores for study only. Arizona’s manufacturing definition turns on propagation, its paraphernalia law makes every offense a felony, and possessing equipment for manufacturing is a felony on its own. Spores for microscopy are a legal hobby; anything that points toward cultivation is where the law starts.

Frequently asked questions

Is it legal to buy mushroom spores in Arizona?

Yes. Arizona’s dangerous-drug definition covers psilocybin and psilocyn and says nothing about spores, which contain neither.

Is it legal to order mushroom spores online in Arizona?

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

Are Psilocybe cubensis spores legal in Arizona?

Yes. The species does not change the analysis; no Psilocybe spore contains a dangerous drug.

Are psilocybin mushrooms legal in Arizona?

No. Possession is a Class 4 felony (often reduced to a misdemeanor or probation for a first offense), and growing them is manufacturing, a Class 2 felony with no probation.

Are mushroom grow kits legal in Arizona?

A kit for culinary species is legal. Equipment intended for cultivating a dangerous drug is paraphernalia under § 13-3415, and using, selling or advertising it is a Class 6 felony. We do not sell cultivation kits or supplies.

Has Arizona legalized psilocybin therapy?

No. The 2024 service-center bill was vetoed, and the 2025 law covers only a future FDA-approved pharmaceutical product.

What is the Arizona mushroom study?

A state-funded PTSD trial of whole psilocybin mushrooms in veterans and first responders, run by the Scottsdale Research Institute under FDA authorization. It does not change Arizona law for the public.

Do you ship spore syringes to Arizona?

Yes, to every Arizona address. The only states we exclude are California, Florida, Georgia and Idaho.
