Moral injury and cannabis use disorder among Israeli combat veterans: The role of depression and perceived social support.

Introduction: Cannabis use is highly common among military combat veterans, who are also inclined toward developing Cannabis Use Disorder (CUD). The present study examined the association between Moral Injury (MI), which may occur following combat-related acts that violate one's deep moral beliefs, and CUD, as well as the mediating role of depression and the moderating role of perceived social support.

Methods: Participants were 215 Israel Defense Forces male combat veterans discharged from military service within the past five years, who reported using cannabis regularly (≥3 days weekly) during the past six months.
