Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are widely prescribed for diabetes and obesity, but studies have found evidence that the medications may also influence behavior, such as supporting impulse control and reducing substance use and alcohol consumption by potentially interacting with the brain's reward and stress systems. New research in Criminology adds to this growing evidence.

When investigators analyzed data from a 2025 nationally representative U.S. survey involving 821 adults who had ever used GLP-1 medications, they found that while impulsivity and alcohol use were strongly associated with committing violent crime, these associations were significantly weaker among current GLP-1 RA users than among former users.

Even when a GLP-1 RA user drinks or acts impulsively, the situation is less likely to escalate into violent criminality. More thorough analyses showed that this finding was especially consistent for impulsivity, but less so for alcohol use.

The findings suggest that GLP-1 RAs may lessen the extent to which certain established risk factors translate into violent behavior.

"As GLP-1 medications become increasingly widespread, understanding their broader behavioral effects becomes an important public health and criminological question that requires careful study," said corresponding author Daniel C. Semenza, Ph.D., of Rutgers University.
