Q. How is marijuana related to mental illness?
A. Marijuana increases the risk of psychosis, in which people lose touch with reality and may experience delusions, hallucinations and paranoia, Volkow says. Marijuana is also associated with chronic psychotic disorders, such as schizophrenia, in people who are genetically susceptible. Heavy marijuana use can lead these people to experience a psychotic episode two to six years earlier than otherwise.
Colorado police have reported two deaths this year related to psychosis-like episodes in pot users. In March, a 19-year-old African exchange student jumped off a hotel balcony after eating a marijuana cookie. The next month, a Denver man who had purchased marijuana, including an edible form called "Karma Kandy," began hallucinating and fatally shot his wife.
