Marijuana use boosts risk of psychosis: study
（the Canadian Broadcasting Corporation - Radio Canada）
LONDON - Teens and young adults who frequently use marijuana are at higher risk of developing psychotic
symptoms later in life, researchers say.
Dutch scientists studied 2,437 young people aged 14-24 to identify their predisposition to psychosis.
Participants were questioned about their use of cannabis and followed for up to four years.
In the study, researchers used a broad definition of psychosis, ranging from occasionally hearing voices and
paranoia to schizophrenia.
Jim van Os of the University of Maastricht in the Netherlands and his team found 21 per cent of cannabis
users had experienced psychotic symptoms compared with 15 per cent among non-users.
