What psilocybin retreats cost in Jamaica and the Netherlands

Oregon and Colorado

Licensed services in the two US states are a different product: a preparation session, a supervised administration session at a licensed centre and an integration offer, not a residential retreat. The state registers publish no prices, so none are shown here.

What a price does not tell you

A higher price does not show better screening or safer care. These are the cited risks to ask any centre about, whatever it charges.

• Lithium: seizure riskSerious risk

  An analysis of online reports found that 47% of 62 reports of lithium taken with a classic psychedelic (such as psilocybin or LSD) involved seizures and 39% involved medical attention, while none of 34 lamotrigine reports did. The authors provisionally concluded psychedelic use may pose a significant seizure risk for people on lithium. (Pharmacopsychiatry, 2021)

• Oregon bars recent lithium usersSerious risk

  Oregon's required Client Information Form asks whether the client has taken lithium in the last 30 days; a yes answer means the client may not participate in an administration session. (Oregon Health Authority, Public Health Division, 2026)

• Psychosis and severe psychiatric historySerious risk

  Published research safety guidelines recommend excluding volunteers with a personal or family history of psychotic disorders or other severe psychiatric disorders, and note prolonged psychoses triggered by hallucinogens are less common than acute distress. Oregon's Client Information Form bars anyone who has ever been diagnosed with or treated for active psychosis. (Journal of Psychopharmacology, 2008; Oregon Health Authority, Public Health Division, 2026)

• Bipolar disorderSerious risk

  In an international survey of 541 people with self-reported bipolar disorder who had used psilocybin, 32.2% described new or increasing symptoms after trips, prominently manic symptoms, sleep problems and anxiety; 3.3% used emergency medical services. The authors say bipolar symptoms may emerge or intensify after psilocybin use. (Journal of Psychopharmacology, 2023)

• No quality control of truffle ceremoniesSerious risk

  The Trimbos Institute's DRUGSinfo warns that nobody checks the quality of truffle or mushroom ceremonies, including intake, aftercare or the number of sober people present, and that a truffle ceremony can be dangerous for people who take medication or have psychological complaints.
