Association of Cannabis Use with Venous Thromboembolism Risk After Traumatic Injury

Conflicting evidence exists on the association between cannabis (THC) use and post-traumatic deep vein thrombosis (DVT) risk. A two-center retrospective analysis of 7365 trauma patients found that THC use was not associated with increased DVT risk. Patients using THC had higher Glasgow Coma Scale scores, shorter hospital stays, and lower rates of pelvic fractures and mortality compared to other drug users. These findings suggest that THC use may not increase DVT risk in trauma patients with adequate chemoprophylaxis.
