LGBTQ+ College Students Show Higher Cannabis Risk Linked to Trauma History
LGBTQ+ college students reported significantly more lifetime trauma and hazardous cannabis use than cisgender-heterosexual peers, with trauma emerging as a key risk pathway.
Quick Facts
What This Study Found
LGBTQ+ students showed greater lifetime trauma (d=-0.79) and hazardous cannabis use (d=0.30) compared to cisgender-heterosexual peers. Lifetime traumatic experiences significantly predicted both hazardous cannabis use and negative cannabis consequences specifically among LGBTQ+ students.
Key Numbers
322 students surveyed. 27% identified as LGBTQ+. LGBTQ+ students had significantly greater trauma (t=−5.90, p<.001, d=−.79) and hazardous use (t=2.18, p=.03, d=.30). Trauma predicted hazardous use (b=0.74, p=.04) and negative consequences (b=0.53, p=.03) for LGBTQ+ students.
How They Did This
Cross-sectional online survey of 322 college students at a northeastern U.S. university. Mean age 19.04 years; 27% LGBTQ+, 77% cisgender-heterosexual; 84% white. Used validated measures of trauma exposure, cannabis use, and cannabis consequences.
Why This Research Matters
Understanding why LGBTQ+ college students face elevated cannabis risk can help develop targeted interventions. This study identifies trauma — not identity itself — as the mechanism, pointing toward trauma-informed approaches rather than identity-based ones.
The Bigger Picture
This fits within broader research on minority stress theory — the idea that marginalized groups face chronic stressors that increase health risks. Rather than cannabis use being inherent to LGBTQ+ identity, it may be a coping response to disproportionate trauma exposure.
What This Study Doesn't Tell Us
Single university, predominantly white sample (84%), cross-sectional design. Cannot establish that trauma causes cannabis use. Self-reported measures. Small LGBTQ+ subsample. Northeastern university may not generalize nationally.
Questions This Raises
- ?Would trauma-informed interventions reduce cannabis harm in LGBTQ+ college students?
- ?Are specific types of trauma more strongly linked to cannabis use?
- ?Do these patterns hold across more diverse samples?

What do these levels mean? →Frequently Asked Questions
Why do LGBTQ+ college students use more cannabis?
This study suggests trauma is the key mechanism — LGBTQ+ students experience significantly more lifetime traumatic events, which in turn predicts riskier cannabis use and more negative consequences.
Is being LGBTQ+ itself a risk factor for cannabis problems?
Not directly. The research suggests minority stress and resulting trauma exposure drive the elevated risk, pointing toward trauma-informed support rather than identity-focused interventions.
