New study makes strong link between use of potent cannabis and psychosis

The study, which examines how cannabis use and strength affects the incidence of psychosis, found that the odds of having the disorder among daily users of the drug were 3.2 times higher than among non-users. The study also discovered that psychosis was five times more likely among those who used high-potency cannabis on a daily basis, and estimated that one in five new cases of psychosis across the 12 sites in the study were linked to daily cannabis use. In Amsterdam, four in 10 (43.8%) new cases of psychosis were estimated to be linked to daily cannabis use, and five in 10 (50.3%) new cases were linked to high potency use.
