LGBTQ+ college students reported significantly more lifetime trauma and hazardous cannabis use than cisgender-heterosexual peers, with trauma emerging as a key risk pathway.
College students, LGBTQ+ individuals, campus health professionals, and counselors working with young adults.
What the researchers 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.
Why it 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 numbers in context
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 the study worked
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.
What this study cannot 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.
How to read the evidence
Single-site cross-sectional study with a predominantly white sample — important preliminary finding but needs replication in diverse populations.
When this study was published
Published in 2026, addressing an understudied area of cannabis health disparities.
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.
Questions still open
- 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?
Common questions
Why do LGBTQ+ college students use more cannabis?
Is being LGBTQ+ itself a risk factor for cannabis problems?
