Cannabis Contributes to 15% of Case of Schizophrenia

A study in Psychological Medicine (May 2, 2023) reported on ” Danish registry data spanning five decades and representing more than 6.9 million people in Denmark to estimate the population-level percentage of schizophrenia cases attributable to (cannabis use disorder) CUD. A total of 60,563 participants were diagnosed with CUD. Three quarters of cases were in men; there were 45,327 incident cases of schizophrenia during the study period. The researchers estimate that in 2021, about 15% of schizophrenia cases among males aged 16 to 49 could have been avoided by preventing CUD, compared with 4% among females in this age range. For young men aged 21 to 30, the proportion of preventable schizophrenia cases related to CUD may be as high as 30%, the authors report.

Editors Note: Other data also support an increased risk for bipolar disorder in those abusing cannabis. The notion that cannabis use carries few risks is baloney. Making pot legal does not make it safe.
