Large study finds a strong link between depression and cannabis use

A new meta-analysis of 55 studies involving more than 3 million people has found that 31% of individuals with cannabis use disorder (CUD) also struggle with major depressive disorder (MDD). While a link between these two conditions has been known for some time, this study provides the clearest evidence to date that the relationship goes both ways. CUD was also found to be present in 10% of those with MDD.
