Public interest in psychedelics and adult use has grown alongside research into their clinical potential. A landscape analysis of online, publicly available information identified 298 organizations offering psychedelic retreats to English-speaking consumers between July and December 2023. Most organizations focused on general wellness rather than religious identity. Ayahuasca was the most commonly offered substance, followed by psilocybin and San Pedro. Retreats were held at 440 distinct physical locations worldwide, with 130 inside the United States and 310 outside. Prices varied widely. Further research into retreat practices is recommended to reduce harm and support consumer education.
Psychedelic retreat organizations vary widely in their safety precautions. All 49 organizations interviewed collected participant medical histories, and 73.5% excluded individuals with certain health conditions. Most required or recommended medication washout periods ranging from one day to over six weeks. While 69.4% worked with a licensed health care professional or someone with emergency response training, only 65.3% had such personnel in attendance at retreats at least some of the time. All organizations offered integration support. The variability in practices, particularly around medication washout and polysubstance use, may increase risks to participants. Best practice guidelines are needed and should be codeveloped with Indigenous and nonclinical communities.
