The United States

One federal law, fifty-one answers.

Federal law

Federal law applies in every state

Under federal law, psilocybin is illegal everywhere in the United States, including in states that license their own psilocybin programs. It has been a Schedule I controlled substance, the most restrictive federal category, since 1971.

In motion: 10 federal actions recorded in 2026, one executive order and nine agency actions. None of them changed the legal status of psilocybin.

States can

  • Write their own criminal laws, and choose not to prosecute
  • License programs, as Oregon and Colorado have

States cannot

  • Shield anyone from federal law
  • Approve psilocybin as a prescription medicine

Nearest date: 14 Sep 2026, the Food and Drug Administration hearing on the possible future medical use of psychedelic drugs.

What changed this year?

This year across the states, newest first. A correction means our reading changed, not the law.

  • New MexicoRegulatory action

    New Mexico has opened applications for psilocybin testing laboratories. The Department of Health said on 5 October 2026 that its online portal for laboratory permits is open, under the producer and laboratory rule that took effect in June. A laboratory permit is for testing psilocybin grown for the programme. It does not let anyone treat a patient, because the rule that would enroll patients and certify clinicians is still a proposal.

  • OregonRegulatory action

    Portland's City Council voted on 30 September 2026 to make the personal, non-commercial use of natural psychedelics, including psilocybin mushrooms, a low priority for law enforcement. The ordinance takes effect on 30 October 2026, excludes peyote and allows no sales. Oregon state law is unchanged.

  • OregonRegulatory action

    Oregon will not raise psilocybin licence fees after all. On 22 September 2026 the Oregon Health Authority said it is dropping the rulemaking that proposed doubling the main licence fees from 1 January 2027 and will not adopt the increases, so the fees businesses pay today stay as they are. The changes in that package that had nothing to do with fees go into a new rulemaking the authority plans to start in the coming weeks, aiming for them to take effect on 15 January 2027. Oregon's legal status is unchanged.

  • New MexicoRegulatory action

    New Mexico has issued its first psilocybin producer permit. The Department of Health said on 18 September 2026 that it has permitted Sacred Alto Spores, that the grower is starting operations, and that it expects to open laboratory permit applications shortly. A permitted grower may only supply practitioners and healing centers once those are certified, and the rule that would certify them is still a proposal going to public hearing on 2 October 2026. No patient can be treated under the programme yet.

  • OregonRegulatory action

    Oregon's proposed rule text now puts figures on the fee increase. A facilitator licence would cost $4,000 a year, up from $2,000, service center and manufacturer licences would double to $20,000, and a worker permit would go from $25 to $200, while the reduced fees now available to nonprofits, veterans and applicants on public benefits would be removed. The state's filed notice says the increases would take effect on 1 January 2027, with laboratories paying the higher fee only from 2029, and it expects the change may shrink the number of licensees. Nothing is final until Oregon adopts the rules, and written comments close on 21 September 2026.

  • ColoradoRegulatory action

    Colorado's Natural Medicine Division has opened rulemaking to carry out House Bill 26-1325, with a stakeholder meeting on 30 September and a final hearing on 4 November 2026, when written comments also close. The proposed topics include temporary premises permits, limited sales licences and testing waivers. The Division also confirms that its emergency rules of 12 August created a limited sales licence for healing centers, and the application form is now available.

  • OregonRegulatory action

    Oregon's psilocybin and medical marijuana programmes are now one section of the state health authority. On 1 September 2026 the Oregon Health Authority merged Oregon Psilocybin Services and the Oregon Medical Marijuana Program into a Medical Cannabis & Psilocybin section led by the psilocybin programme's existing manager, and the state says services and processes carry on without disruption while forms and web pages take the new name over the coming months.

  • OregonRegulatory action

    Oregon took public comment on a petition to change the rule that governs how psilocybin facilitator training programmes get their curriculum approved. The comment period closed on 29 August 2026. This is a separate track from the state's larger annual rule changes.
