The Cannabis and Psychosis Awareness Project, a four-year study from Canada that was released on Tuesday, finds that smoking marijuana – particularly heavy use in early adolescence – is associated with a 40% increased risk of psychosis. Youth with a family member identified as having a mental illness are 4x more likely to develop psychosis if they use marijuana, the study says. 50 young Canadians who participated in the study created the video Awareness Strategy for Youth.
