Psilocybin retreats, and the wider retreat map
A retreat is the loosely regulated cousin of a licensed service center: lawful where the compound was never scheduled, customary where tradition covers it, and a gray zone anywhere that won't say. We index 214 retreat records in 16 countries, about 203 distinct operators. 172 of those records carry a stated legal basis and the rest carry none — that gap is the fact the glossy retreat sites leave out.
What the retreat world actually offers
Psilocybin leads, but the retreat map is wider than one molecule: ayahuasca centers cluster in Peru and Costa Rica under traditional-use protections, and ibogaine programs (Mexico, Costa Rica, Canada hold the largest shares) sit in their own risk class entirely; cardiac screening there is non-negotiable, not a nicety.

Read a retreat record like a clinician
Three checks before anything else. The legal basis: if a center can't name the statute or scheduling status it operates under, that silence is the answer. Screening: ask what conditions and medications they exclude, and walk away from anyone who says "none." Staffing: a physician or licensed therapist on site is the difference between a retreat and a vacation with a liability waiver. Four records from the list, one per operator, with the legal-basis line each one carries:

US residents have supervised options under actual state regulation: Oregon's 24 OHA-licensed service centers and Colorado's 47 approved healing centers. And recruiting clinical trials remain the no-cost, fully legal route in the other 48 states.
