Are Psilocybin Retreats Legal?

Psilocybin retreats are legal in a short list of places and illegal across most of the world. We run ayahuasca retreats in Colombia, and every week we speak with people who were given inaccurate information about the law by someone selling them a ceremony. Oregon and Colorado license supervised psilocybin sessions inside their own state programmes. Jamaica never wrote psilocybin into its drug law. Dutch centres serve truffles rather than mushrooms, and the Dutch statute draws that line deliberately.

Anywhere not named below, treat it as illegal until you have read the law yourself. The list is not exhaustive. Drug law changes, sometimes inside a single legislative session, so confirm the current status before you pay a deposit. Every claim below carries a source you can open. Legal status last checked 4 September 2026.

Which Laws Allow a Psilocybin Retreat

Oregon, Colorado, Jamaica and the Netherlands are the four places where a psilocybin retreat can point at something specific in law. Only Oregon and Colorado have a regulator behind them. Jamaica and the Netherlands rest on an absence of law rather than on a permission, and nothing stops a legislature closing that gap between your deposit and your flight.

The place-by-place picture, including the countries that are not covered here, is set out in our guide to psilocybin retreats country by country.

Every one of those four carries conditions, and the conditions are set out below, one place at a time.

Oregon’s Licensed Psilocybin Services

Oregon licenses psilocybin sessions through a state programme, and psilocybin stays illegal in Oregon outside it. Voters passed Measure 109 in 2020. The state codified it as ORS chapter 475A and handed it to the Oregon Health Authority to run. Licence applications opened on 2 January 2023, and service centres opened to clients in the summer of that year.

Four things about the programme surprise people.

• You have to be 21 or older, and so does the facilitator.
• A facilitator needs a high school diploma, a training course the Oregon Health Authority approves, and a passed state exam. Not a medical licence. ORS 475A.325 sets that list out in full.
• You take the psilocybin at the licensed service centre under supervision, and none of it goes home with you. That is ORS 475A.498, by name.
• A preparation session before and an integration session after are both written into the statute, at ORS 475A.345 and ORS 475A.360.

The facilitator point is the one worth sitting with. Oregon built a supervised-session programme rather than a medical one. It can be that the facilitator you get has years of sitting behind them. It can also be that they hold the minimum the statute asks for, which is a diploma, a course and an exam. Oregon law does not sort those two apart, and neither will a retreat website.

None of ORS chapter 475A touches federal law. It does not make Oregon a place you can carry mushrooms around in either. ORS 475A.530 lets a locality set its own time, place and manner rules for service centres. An Oregon address on a map does not mean a service centre near it.

Colorado’s Natural Medicine Health Act

Colorado did two separate things in 2022, and people run them together. Proposition 122, the Natural Medicine Health Act of 2022, removed state criminal penalties for adults 21 and over who possess, use, grow or share entheogenic plants and fungi. It also set up a licensed healing-centre system, which is a different thing with different rules.

The Act is explicit that sharing is not the same as selling. It does not permit anyone to distribute or sell those plants and fungi for remuneration as part of a business promotion or other commercial activity. Personal use and passing some to a friend sit inside the decriminalisation. A paid retreat sits outside it and needs the licence.

On the regulated side, the Act as passed puts licensing with the Department of Regulatory Agencies. A licensed facilitator supervises the session, and the Act allows it to happen at a healing centre or at another location the department’s rules permit.

Until 1 June 2026 the Act limited natural medicine to psilocybin and psilocyn only. After that date the department may add dimethyltryptamine, ibogaine and mescaline other than peyote, on a recommendation from its advisory board. Whether the department has added any of them is a question for the centre, not for a website: ask for the rule that allows what it is offering.

A Colorado locality can regulate the time, place and manner of a healing centre. Under section 12-170-107 of the Act it cannot ban them outright, which is where Colorado and Oregon part company.

Jamaica and the Netherlands Rest on a Gap

Jamaica and the Netherlands are the other two, and both rest on something a legislature left out rather than on something it granted. Psilocybin was never written into Jamaica’s Dangerous Drugs Act, so there is no licence to hold, no age limit set by a psilocybin statute, and no regulator watching retreats. Legal and regulated are different words, and Jamaica has the first without the second.

The Netherlands drew its line inside the statute instead. List II of the Dutch Opium Act names psilocybin-containing mushrooms species by species, from agrocybe farinacea down a long alphabetical list to psilocybe zapotecorum, and sclerotia, sold as truffles, are not on it. The ministerial answer and the 2008 Staatsblad text behind both positions are quoted in full in our guide to psilocybin retreats country by country.

Colombia and Costa Rica

Two countries come up constantly and we are not going to state a position on either. Colombia is the first. Harmonica runs ayahuasca retreats in Colombia and we have published no position on psilocybin there, so this is not where you should get one. If Colombia is your real question, bring it to a consultation call and ask it directly.

Costa Rica is the second, for a different reason. It has a large retreat scene and no statute that licenses any of it, which our guide to psilocybin retreats country by country sets out in full with sources.

Everywhere else, the answer is the one we give for ayahuasca. Assume illegal until a named statute says otherwise, and treat a retreat’s own website as marketing rather than legal research.

Psilocybin Is Schedule I Under US Federal Law

Psilocybin and psilocyn are both Schedule I controlled substances under United States federal law, and neither Oregon nor Colorado changes that. 21 CFR §1308.11(d) lists psilocybin at Drug Enforcement Administration code 7437 and psilocyn at 7438, among the hallucinogenic substances in Schedule I.

Two consequences get missed.

• A state programme is a defence against state prosecution and not against federal prosecution. Oregon and Colorado wrote their programmes knowing that. What has left them alone so far is federal enforcement policy, and policy is not statute.
• Dose does not matter. There is no microdose exemption anywhere in federal drug law. A tenth of a gram of dried mushrooms is the same Schedule I possession as a full dose. The only thing that changes is how likely anyone is to notice.

How federal scheduling collides with state law is set out at length on our page about whether ayahuasca is legal in the US, using a different molecule. The mechanics are identical, and so are the ways retreats misdescribe them.

What the FDA Designations Mean

An FDA breakthrough therapy designation is not an approval and it changes no drug’s legal status. The FDA grants it when preliminary clinical evidence suggests a drug may be substantially better than the therapy already available, and what it does is speed up development and review.

Psilocybin has held one since 2018, when Compass Pathways received it for COMP360 in treatment-resistant depression. Two Phase 3 trials have reported since. COMP005 ran 258 patients on a single 25mg dose against placebo. It met its primary endpoint in June 2025, a 3.6-point difference on the Montgomery-Åsberg Depression Rating Scale at six weeks. COMP006 ran 581 patients and met its endpoint in February 2026, a 3.8-point difference for two 25mg doses against a 1mg comparator. The FDA then granted a rolling review of the new drug application, and issued a National Priority Voucher in April 2026.

None of that is an approval, and an approval on its own would not be legalisation either. Compass Pathways says as much in its own quarterly filing with the Securities and Exchange Commission. COMP360 contains a Schedule I controlled substance, so the Drug Enforcement Administration would have to reschedule it. States would then have to do the same before a doctor could prescribe it. The sequence runs approval, federal rescheduling, fifty state decisions. A retreat telling you psilocybin is about to be legal has skipped two of those three steps.

How to Check a Retreat’s Legal Claim

Ask for the statute rather than the reassurance. A retreat operating legally can name the law it operates under in one sentence. The ones that cannot will offer you a paragraph about tradition instead, and the swap is easy to spot once you are listening for it.

Five questions get you most of the way.

1. Which law lets you do this? A licensed Oregon or Colorado centre gives you a licence number. A Jamaican one tells you psilocybin is not in the Dangerous Drugs Act.
2. Who regulates you, and can I look you up? In Oregon that is the Oregon Health Authority, and its licensee directory lists every service centre and facilitator by name. In Jamaica the answer is nobody, and a straight operator will say so without being pushed.
3. What are you actually serving? In the Netherlands the answer should be truffles.
4. What is your screening list? Somewhere that does not ask about SSRIs, lithium, bipolar disorder or a family history of psychosis is not somewhere to hand over your nervous system.
5. What happens at three in the morning if it goes wrong? The answer should involve a phone, a car and a named hospital.

This page is not for you if you have already chosen a country that is not named above and want confirmation it is fine. Nobody can give you that from a website, and a retreat that gives it to you is selling. Take the country to a lawyer who practises there, or bring it to a consultation call and we will tell you which of the two you need.

What would change our answer is straightforward. If the FDA approves COMP360 and the Drug Enforcement Administration reschedules psilocybin, most of the United States position above stops being true, and we will rewrite it.

If you are weighing ayahuasca against magic mushrooms, or working out whether psilocybin retreats are legal somewhere you can travel to, book a free consultation call and ask. Part of that call is us telling you when the person you need is a lawyer rather than a facilitator.
