Cannabis usage and addiction had been linked to an increased risk of psychiatric disorders. However, the association has not been well-characterized in the literature. This prospective cohort study was conducted in Denmark to examine the the relationship between cannabis use disorder to depression and bipolar disorder
The study followed more than 6.6 million participants between 1995 and 2021. The researchers found that cannabis use disorder increased the risk of unipolar depression by 84%. This elevated risk is true in both psychotic and nonpsychotic unipolar depression. Cannabis usage is also associated with a 196% higher risk of bipolar disorder in men and 154% in women. In terms of psychosis in bipolar disorder, cannabis use disorder is linked with more cases of the psychotic subtype than the nonpsychotic subtype. The authors of this study would like to highlight that the many mild cases of depression could have been managed in a primary care setting and would not have been included in the database.
