While cannabis use in the military is low, with the expansion of legalization of marijuana, particularly for medical use, the authors review the current evidence for use of cannabis products for treatment of pain and post-traumatic stress disorders (PTSD). After review of meta-analysis, the authors found no benefit for pain with the use of cannabinoids; further, studies suggested any perceived benefits by patients were attributable to placebo effect. Similarly, across multiple studies, there did not appear to be any benefit from cannabinoids for treatment of PTSD. Based on current evidence, the authors state cannabinoid for treatment of PTSD or pain in military personnel or veterans is not supported.
