In this eye-opening first part of our conversation with Ed Prideaux, we explore the world of Hallucinogen Persisting Perception Disorder (HPPD). Ed, a researcher and someone who has personally experienced HPPD, provides a comprehensive explanation of this rare condition that can occur after psychedelic use. He discusses:

1. The definition and symptoms of HPPD
2. His personal journey with the condition
3. The varying degrees of HPPD severity, from mild to debilitating
4. The potential link between adolescent psychedelic use and HPPD
5. The challenges of diagnosis and self-diagnosis
6. The intersection of HPPD with other conditions like depersonalization and derealization

Ed offers valuable insights into the complexities of HPPD, shedding light on a condition that is often misunderstood or overlooked in discussions about psychedelic use. Listener discretion advised.
