The Dark Side of Psychedelics - Mattha Busby - Zoom

The Dark Side of Psychedelics - Reporting on the dark side of the psychedelic renaissance

As a journalist reporting on the psychedelic world at the same time as having his own experiences, for both research and as part of a personal quest for growth, Mattha Busby has seen it all. Ceremonies bathed in love and light, and rituals steeped in darkness. Through all of this, he has witnessed and experienced both the benefits of psychedelics and their serious potential for harm. To tell this story, Mattha embarks on a rip-roaring journey through a brave—and profoundly weird—new world in which psychedelics are more available than ever before in human history. Retreat organizers are paying for targeted ads on Instagram, and giving celebrities free trips in exchange for positive testimonials. Illegal psychedelic dispensaries have popped up on high streets, and vendors are selling psychedelic toad venom on tropical beaches and in hotels, often without adequate safety measures.

For many, these psychedelic experiences have provided welcome relief from a near-constant sense of anxiety, but others have been left dazed and confused, or worse, and with few avenues for support. In rare cases, people have even died at psychedelic retreat centers, and at clinics, though we often do not hear about this until someone investigates. Some of these incidents have highlighted the folly of erasing the reality of the darker aspects of shamanism in popular representations and denying the sometimes radical cultural differences between those who serve psychedelics and those who receive. There has been scant discussion of how many of the traditional uses of ayahuasca were for sorcery and other nefarious purposes.

Ultimately, it can be difficult to deduce good psychedelic facilitators between the less well-intentioned until you've spent time with them. But increasing numbers of people around dinner tables now tell of destabilising journeys and touchy shamans. There are no easy answers to all of this — but the first step would be leaders in the psychedelic industry accepting this fact and not dismissing critiques as ill intentioned tellings of isolated incidents.
