Abstract:

The objective of this study was to assess the association between cannabis use disorder (CUD) and self-injury among veterans. As expected, after adjusting for sex, age, sexual orientation, combat exposure, traumatic life events, traumatic brain injury, posttraumatic stress disorder, depression, alcohol use disorder, and noncannabis drug use disorder, CUD was significantly associated with both suicidal (OR  =  3.10, p  =  .045) and nonsuicidal (OR  =  5.12, p  =  .009) self-injury. CUD was the only variable significantly associated with self-injury in all three models examined. These findings are consistent with prior research among civilians and suggest that CUD may also increase veterans' risk for self-injurious behavior.
