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?

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.
