In this gripping documentary, scientists and survivors uncover the hidden mental health dangers of cannabis use. Through personal stories and cutting-edge research, HIGH RISK explores the unsettling link between cannabis and psychosis—delving into hallucinations, paranoia, and long-term mental health consequences. We’ll hear the story of 19-year-old Johnny Stack, who died by suicide after becoming psychotic from dabbing high-potency THC, and Bryn Spejcher, who stabbed a man to death in 2018 while in the depths of a cannabis-induced psychotic episode.
