Psychedelic Sitters School was established in 2012 through the Center for Medicinal Mindfulness, first as a Psychedelic Harm Reduction and Peer Support training, and once cannabis was legalized in Colorado in 2014, as a professional psychedelic therapy and guide training program for psychotherapists and non-therapist alike . Since COVID-19, we have reimagined the program and have switched to an online/small group hybrid, and added additional information on a professional credentialing program.
