Psilocybin is a psychedelic drug compound found in certain types of mushrooms, which, when ingested, produce powerful hallucinations and other mind-altering effects including changes in perception, a distorted sense of time, and mystical or spiritual experiences. There is evidence that the use of psilocybin mushrooms by humans in religious ceremonies predates recorded history, and they have a long-documented history in both Mesoamerican and Siberian Indigenous culture. In a modern context, there have been several recent studies conducted to test psilocybin’s efficacy in a variety of therapeutic settings, most specifically for treating depression. Psilocybin has also been used to treat ailments including cluster headaches, obsessive-compulsive disorder, anxiety, PTSD, and addiction. We’ve started gathering valuable information on this topic, but haven’t yet curated the findings.
