Marijuana use has been reported to promote hypercoagulable states among trauma patients, particularly respecting venous thromboembolism (VTE), a major contributor to morbidity and mortality in patients sustaining traumatic injury. We sought to investigate this further through a retrospective, single institutional study performed from January 2018 through June 2021, utilizing data from patients presenting to a Level 1 Trauma Center as a trauma activation. We observed less frequent VTE development in the marijuana-positive group compared to the marijuana-negative group, with patient thromboelastography revealing a longer mean R-time in the marijuana-positive group. Overall occurrence of VTE was too low for definitive conclusions, but a trend toward reduction in VTE frequency among marijuana users compared to nonusers was noted. More studies with larger populations and more VTE occurrences are needed to confirm a potential correlation between marijuana use and VTE development
