Psilocybin therapy is legally available in Oregon right now, with Colorado close behind. Beyond those two states, clinical trials at major research institutions offer another path, and international retreats in Jamaica and the Netherlands provide legal options for those willing to travel. Where you go depends on your location, budget, and whether you qualify for a specific program.
Oregon: The Only Fully Operational U.S. Program
Oregon is currently the only state where any adult can walk into a licensed service center and receive psilocybin. Voters approved Measure 109 in 2020, and the Oregon Health Authority published final rules in 2022. The state now maintains a public licensee directory where you can search for licensed service centers and facilitators by location. You contact a service center directly to schedule services.
No diagnosis is required. Oregon’s program is not structured as medical treatment. It’s a supervised wellness service open to adults 21 and older. Each session follows a three-part model: a preparation session where you meet your facilitator, discuss your intentions, and learn what to expect; the administration session itself, during which a licensed facilitator stays with you the entire time; and an integration session afterward to help you process the experience.
The catch is cost. Oregon does not regulate pricing, so each service center sets its own fees. Full experiences (preparation, dosing session, and integration) commonly run between $1,500 and $3,500, though prices vary widely. Insurance does not cover it. To find a center, start at the Oregon Health Authority’s OPS Licensee Directory, which lists every licensed service center and facilitator in the state.
Colorado: Opening Soon
Colorado passed Proposition 122 in 2022, creating the Natural Medicine Health Act. The state appointed its advisory board in 2023 and opened facilitator licensing through the Department of Regulatory Agencies (DORA) in December 2024. Approved training programs are already listed on DORA’s website, and facilitators are actively getting licensed, with current licenses valid through January 2026.
The full scope of Colorado’s program is still taking shape. Unlike Oregon, Colorado’s law also covers other natural medicines beyond psilocybin. If you’re in Colorado and want to be among the first to access services, check DORA’s Natural Medicine homepage for updates on when licensed healing centers begin accepting clients. The infrastructure is being built now, so availability will expand throughout 2025.
Clinical Trials Across the U.S.
If you don’t live near Oregon or Colorado, clinical trials are the most accessible legal route. Psilocybin has received multiple FDA breakthrough therapy designations, which means several large trials are actively recruiting participants. The advantage: treatment is free. The tradeoff: you may receive a placebo, and eligibility criteria are strict.
NYU Langone alone is currently recruiting for studies covering major depressive disorder, postpartum depression, alcohol use disorder, smoking cessation, and anxiety and depression in advanced cancer. Other major research universities run similar programs. ClinicalTrials.gov lets you search by condition and location to find studies near you.
Each study targets a specific population. The major depression trial, for example, evaluates a single 25 mg dose of psilocybin against placebo, measuring changes in depressive symptoms over 43 days. The smoking cessation study pairs two psilocybin sessions with psychotherapy over about two weeks. Most trials include the same three-phase structure used in Oregon: preparatory sessions, the dosing day, and integration afterward.
Who Cannot Participate
Whether you’re applying for a clinical trial or visiting a service center, certain conditions are firm disqualifiers. The most important: anyone with a personal history of schizophrenia, psychotic disorders, or bipolar disorder (type I or II) is excluded from virtually every psilocybin program. This isn’t overcaution. Psilocybin can trigger psychotic episodes or manic states in people with these conditions.
Cardiovascular concerns also matter. Trials typically exclude people with recent coronary artery disease, stroke, uncontrolled high blood pressure, or certain heart rhythm abnormalities. A history of seizures, dementia, or cerebral aneurysm will also disqualify you. Most programs exclude anyone with a moderate to severe substance use disorder within the past year (other than caffeine or tobacco), and anyone with a recent medically significant suicide attempt.
Oregon’s service centers conduct screening during the preparation phase, and facilitators can decline to proceed if they identify risk factors. Clinical trials use more formal medical evaluations, including physical exams and sometimes heart monitoring.
International Retreats
Jamaica and the Netherlands are the two most established international destinations. In Jamaica, psilocybin mushrooms have never been scheduled or prohibited under the Dangerous Drugs Act. They’re simply unregulated, which means retreat centers operate legally and openly. Retreats typically run five to seven days and include multiple facilitated sessions, group processing, and sometimes yoga or breathwork. Prices range from roughly $2,500 to $7,000 depending on the provider and accommodations.
In the Netherlands, psilocybin mushrooms themselves are banned, but psilocybin truffles (a different growth form of the same organism) remain legal. Dutch retreat centers use truffles in supervised sessions, often in a group setting. The experience is pharmacologically identical. Costs are generally comparable to Jamaican retreats.
Neither country requires a medical referral or diagnosis. The quality and safety protocols of retreat centers vary enormously, so look for programs that include medical screening, trained facilitators, preparation sessions, and integration support. A center that skips screening is a red flag regardless of jurisdiction.
What the Experience Looks Like
Across all legal settings, psilocybin therapy follows roughly the same structure. The preparation phase, usually one or two sessions, is where you build rapport with your facilitator, set intentions, and learn what to expect physically and emotionally. This step matters. Research on psychedelic-assisted therapy consistently emphasizes that the relationship between participant and facilitator, along with the physical environment, significantly shapes outcomes.
The dosing session itself lasts about six to eight hours. You’ll typically lie down in a comfortable room, sometimes wearing an eye mask and listening to music. Your facilitator stays present the entire time but doesn’t direct the experience. Effects usually begin within 30 to 60 minutes and peak around two to three hours in. Experiences range widely, from visual imagery and emotional release to difficult or frightening passages that facilitators help you move through.
Integration comes afterward, sometimes the next day, sometimes over several weeks. This is where you work with your facilitator or therapist to make sense of what came up during the session and connect it to your daily life. Many practitioners consider integration the most important part of the process.
Cost and Insurance
Psilocybin therapy is almost entirely out of pocket right now. No major insurance provider covers it, and Oregon explicitly has no authority to regulate pricing. However, the groundwork for future coverage is being laid. In 2023, the American Medical Association created the first billing codes specifically for psychedelic-assisted therapy: three Category III codes that went into effect January 1, 2024. These are temporary tracking codes, not a guarantee of reimbursement, but they allow hospitals and clinics to start reporting psychedelic therapy services in a standardized way. This data collection is considered a necessary first step before Medicare, Medicaid, or private insurers build coverage policies.
For now, if cost is a barrier, clinical trials remain the only free option. Some Oregon service centers offer sliding scale pricing, but availability varies. When comparing retreat or service center prices, check what’s included. A lower headline price sometimes excludes the preparation and integration sessions, which you’ll want regardless of where you go.
How to Verify a Facilitator’s Credentials
In Oregon, every licensed facilitator must complete an approved training program and pass an exam administered by Oregon Psilocybin Services. You can verify any facilitator’s license through the state’s public directory. Colorado uses a similar model through DORA, requiring completion of an approved training program and a formal application for licensure.
Several universities now offer approved facilitator training for both states. Naropa University, for example, runs a certificate program approved by both Oregon and Colorado, and portability of licensure between the two states is expected. If a facilitator claims to be licensed, you should be able to confirm it through the relevant state directory. Anyone offering psilocybin services in a state where it isn’t legal, regardless of their training, is operating outside the law.
