For an American adult, there are four places where psilocybin can be taken without breaking the local law, and they work in completely different ways: supervised access without a diagnosis in Oregon and Colorado, a state medical program in New Mexico that has not yet opened, and Jamaica, where psilocybin was never scheduled at all. None of them changes US federal law, under which psilocybin is a Schedule I controlled substance.
This page sets the four side by side: what the law actually allows, who is in the room, whether a diagnosis is needed, and what follows you home. It is not legal advice, and it is not a recommendation to travel anywhere.
Where is psilocybin legal in the United States?
In two states, adults can access it under supervision: Oregon, under Measure 109, and Colorado, under Proposition 122. New Mexico has passed a Medical Psilocybin Act, but its program is not yet treating patients. Under federal law psilocybin and psilocyn remain Schedule I controlled substances, and that federal law still applies in every state, including Oregon and Colorado. The full comparison is on where psilocybin is legal.
Do you need a diagnosis in Oregon or Colorado?
No. Neither state requires a diagnosis, a prescription or a referral. In Oregon any adult aged 21 or over may access services at a licensed service center: a preparation session, a supervised administration session and an optional integration session. Colorado licenses “healing centers” that provide supervised access to adults.
Who supervises the session in Oregon and Colorado?
A licensed facilitator, a role that does not require a clinical qualification. In Colorado, facilitators are regulated by the Department of Regulatory Agencies, not by a medical board, which is the clearest single indication that these are not medical frameworks. Whether that is better or worse depends on what you need, but it is a different thing from a prescription.
What about New Mexico?
New Mexico’s Medical Psilocybin Act creates a state program in which licensed clinicians with a Department of Health permit give psilocybin to qualified patients in approved settings, with a preparation, an administration and an integration session. The qualifying conditions in the law are major treatment-resistant depression, post-traumatic stress disorder, substance use disorders and end-of-life care. The law has been in force since 20 June 2025, but the program is not yet treating patients. The Department of Health has set a target of 31 December 2026, and the law requires it to be running by 31 December 2027.
Is psilocybin legal in Jamaica?
It is not prohibited. Jamaica’s Dangerous Drugs Act, the law that defines the country’s drug offenses, has never listed psilocybin or psilocin. That is a narrower statement than “legal” usually suggests: no license is specific to psilocybin services, no law sets their screening, dosing or staffing, and the Ministry of Health and Wellness has approved no psilocybin product. Our Jamaica legal reference sets out each law with its source.
Can you bring psilocybin back to the United States?
No. Psilocybin and psilocyn are Schedule I controlled substances under US federal law, and so is any material that contains them, which includes the mushrooms. Importing a Schedule I substance without authorization is a federal offense. Jamaica’s law stops at its border. Do not pack it.
Which option includes medical screening?
None of them by law, except New Mexico’s program once it opens. Oregon and Colorado require no diagnosis and no clinician, and Jamaican law sets no screening standard at all. In practice, screening is whatever the provider decides it is, so ask before you book: who screens you, what rules someone out, and who is in the room.
Which one is right for you?
It depends on what you need. If you want a licensed framework on US soil and do not need medical oversight, Oregon and Colorado are built for that. If you have one of New Mexico’s qualifying conditions and want a medical route, its program is the one to watch. If you want psychiatric and medical screening, a clinical team present and months of structured work afterward, that is something a provider has to build, wherever the sessions take place.
The four side by side
The full comparison of ten jurisdictions, with the statute behind each, is on where psilocybin is legal.
Oregon
Supervised adult access under Measure 109 (ORS 475A), for adults aged 21 or over, at a licensed service center. No diagnosis. Led by a licensed facilitator who need not be a clinician. Licensing opened 2 January 2023.
Colorado
Supervised adult access under Proposition 122 and SB23-290, at licensed healing centers. No diagnosis. Facilitators regulated by the Department of Regulatory Agencies, not a medical board. First regulated session 6 June 2025.
New Mexico
A state medical program for four qualifying conditions, run by licensed clinicians with a Department of Health permit. In force since 20 June 2025; not yet treating patients.
Jamaica
Never scheduled under the Dangerous Drugs Act, so no permission is needed and none is available. No license, standard or approved product. Screening and staffing are set by each provider.
Where our program fits
We are not a US service, and we say so plainly. Our residencies take place in Jamaica, at a private site, one client at a time. Because Jamaican law sets no standard, we set our own: psychiatric and medical screening before acceptance, two trained facilitators in the room for the whole of every session, a dual board-certified nurse practitioner on site throughout the residency, and six months of one-to-one work around three seven-day residencies.
