- Rutgers University researchers published a study in the journal Criminology finding that GLP-1 drugs like Ozempic and Wegovy may weaken the link between impulsivity and violent behavior in adults.
- The study analyzed data from a 2025 survey of 7,521 US adults, with the main analysis focusing on 821 people who had used a GLP-1 medication at some point.
- The relationship between impulsivity and violent behavior was about 62% weaker among current GLP-1 users compared to former users, the study's strongest finding.
- The connection between alcohol use and violent behavior was about 52% weaker among current users, though those results were less consistent across additional sensitivity analyses.
- Lead author Daniel Semenza, director of research at the New Jersey Gun Violence Research Center, said understanding the behavioral effects of these increasingly widespread drugs is important for public safety.
- Coauthor Christopher Thomas compared the medications' apparent effect to cognitive behavioral therapy, saying they weaken 'the path from impulse to action rather than eliminating impulsivity itself.'
- Researchers cautioned the study is observational and cross-sectional, meaning it can identify associations but cannot prove causation; they called for longitudinal and experimental studies to confirm the findings.
Why it matters: With a 62% attenuation of the impulsivity-violence link among current GLP-1 users versus former users, the finding is the strongest signal yet that these blockbuster drugs may alter behavior beyond appetite. But the cross-sectional design means the result identifies association only — and the researchers themselves explicitly call for longitudinal and experimental work before any public safety claims can be made.
