“Cannabis use has been reported to affect the course of various psychiatric disorders, however its effect on the course of major depressive disorder (MDD) is not yet clear.
After adjusting for baseline confounding factors, no associations were found between cannabis use and suicidality, functionality and quality of life.
We conclude that many of the associations between cannabis use and a more severe course of MDD do not seem to be attributed to cannabis use itself but to associated sociodemographic and clinical factors.”
