Cannabis Use and Violent Behavior in Young US Adults: Complex Sex-Specific Patterns
Among 113,000 young US adults, daily cannabis use was associated with 1.7-1.8x higher violent behavior in males specifically with or without CUD, while in females any cannabis use was associated with 1.6-2.4x higher odds regardless of frequency or CUD status.
Quick Facts
What This Study Found
For males, only daily cannabis use (with or without CUD) was associated with violent behavior (adjusted PRs: 1.7-1.8). For females, cannabis use at any frequency and CUD status was associated with violent behavior (adjusted PRs: 1.6-2.4). The sex-specific patterns suggest different pathways linking cannabis to violent behavior in men and women.
Key Numbers
113,454 participants aged 18-34. 28.9% past-year cannabis use. Males: daily use without CUD PR=1.7, daily with CUD PR=1.8 (vs no use baseline 1.7%). Females: any cannabis use PR=1.6-2.4 (vs no use baseline 1.0%).
How They Did This
Analysis of 113,454 participants aged 18-34 from the 2015-2019 National Surveys on Drug Use and Health. Cannabis use (daily/non-daily, with/without CUD by DSM-IV) and violent behavior (attacking someone with intent to seriously harm) were assessed. Multivariable logistic regression with sex stratification.
Why This Research Matters
Young adults commit 52% of violent crimes but are only 23% of the population. Understanding how cannabis use intersects with violence risk in this demographic has direct implications for prevention and risk assessment.
The Bigger Picture
The sex-specific pattern is important: in males, only daily use matters, suggesting a dose-response or chronic exposure mechanism. In females, any use is associated, suggesting either a lower threshold or different confounding structure.
What This Study Doesn't Tell Us
Cross-sectional design cannot determine directionality. Violent behavior may lead to cannabis use rather than vice versa. Self-reported measures may underestimate both cannabis use and violent behavior. Cannot control for all confounders.
Questions This Raises
- ?Does cannabis use directly increase violence risk, or are both driven by shared factors?
- ?Why is the female association present at any use level?
- ?Would longitudinal data clarify the causal direction?

What do these levels mean? →Frequently Asked Questions
Is cannabis use linked to violence?
In this national study, daily cannabis use was associated with higher violent behavior in males (1.7-1.8x), while any cannabis use was associated in females (1.6-2.4x). The study cannot determine if cannabis causes violence or if shared factors explain both.
Why is the pattern different for men and women?
The researchers found males showed elevated violence only with daily use, while females showed elevated violence at any use level. This suggests different mechanisms or threshold effects by sex, though the reasons remain unclear.
