Among lifetime marijuana users (n = 315), prevalence of lifetime MD was 12.1%. Within the lifetime marijuana use sample (n = 315), 275 (87.3%) reported any trauma exposure; among those TE individuals, mean PTSD symptoms was 3.17 (sd=3.61). Trauma load was not associated with increased risk for MD; however, individuals with MD showed significantly greater mean PTSD symptoms (Table 1). After controlling for demographic variables, each additional PTSD symptom increased odds of MD by 1.1 (Table 3). Results for MD were consistent when controlling for AD and ND in that MD was not related to TE and was related to PTSD.
