In December of 2021 the PBS program NOVA released a short video exploring the link between marijuana use and psychosis.

In the video, mental health experts weigh the dangers of marijuana-use — especially among young people.

Since the release of this video, research has emerged estimating that as many as 30% of schizophrenia cases among men between the ages of 21 and 30 might have been prevented by not using marijuana.
