Episode 72: When The Trip Doesn’t End with Ed Prideaux
Psychedelics and other drugs can trigger a condition called Hallucinogen Persisting Perception Disorder, a terrible name for a real condition that we don’t have much data on and is poorly understood. But while it’s clear that psychedelics shouldn’t be illegal, it’s also clear we’re still learning about some of the risks. This fascinating and often distressing phenomenon deserves a closer look, but not everything about it is devastatingly tragic, either.
In this episode of Narcotica, co-host Troy Farah talks all about HPPD with Ed Prideaux, a master’s student in psychology at the University of East London with a background in journalism. Ed is currently focused on researching and addressing the problems, possibilities and questions raised by HPPD: a broad, under-researched and not entirely uncommon condition in which people experience sustained and distressing changes to their visual perception (among other effects) after psychedelic trips. Ed has lived with these visual effects for nearly seven years, and is affiliated with a nonprofit launched last year to promote harm reduction around HPPD called the Perception Restoration Foundation.
