File on 4 Investigates - Trip Shocked

Download Trip Shocked

Psychedelics are having a moment — hailed as miracle cures for depression, PTSD and addiction. But what happens when the trip doesn’t end?

In Trip Shocked, writer and researcher Ed Prideaux takes a hard look at the risks lurking in the psychedelic renaissance. Drawing on his own long-term side effects from LSD, Ed explores a hidden history of harms: from persistent hallucinations and underground support groups to therapy sessions that crossed the line.

As billionaires, biotech firms and media stars race to mainstream psychedelics, are we ignoring inconvenient truths about safety, science and consent?
