About a year ago, Rutgers University researcher Daniel Semenza was listening to a podcast about an expansive study of GLP-1 medications when a question occurred to him.
The 2025 study , published in Nature Medicine , had examined millions of Department of Veterans Affairs records to map the potential benefits and risks of glucagon-like peptide-1 receptor agonists, a class of drugs better known by brand names like Ozempic, Wegovy, and Zepbound.
In addition to treating diabetes and obesity, the medications appeared to affect substance use, impulse control, and other behaviors associated with the brain’s reward system.
Researchers and patients had also begun reporting possible reductions in compulsive shopping, gambling, skin picking, and other repetitive behaviors.
“The lightbulb kind of went off,” Semenza told us.
“What about aggression?
Or what about violence?”
Semenza, who is research director at the New Jersey Gun Violence Research Center, knew that impulsivity and substance use — particularly alcohol use — are two established risk factors for violent behavior, including gun violence.
His question became the basis of a new study he conducted with Christopher Thomas, a Rutgers University professor of sociology, anthropology, and criminal justice.
Published in June in the journal Criminology , their resulting study suggests that GLP-1s may somehow blunt the links between impulsivity, alcohol, and violence.
It found that associations between impulsivity and violence, and alcohol and violence, were weaker among people currently taking GLP-1 medications than among those who had stopped taking them.
The association between impulsivity and violence was about 62 percent weaker among current users of the medications than among former users, according to the study.
The association between alcohol use and violence was about 52 percent weaker.
The findings are a preliminary look at GLP-1s and violence and do not necessarily suggest that GLP-1 drugs make people less impulsive, Semenza said.
Instead, the medications may affect whether an impulsive tendency turns into an aggressive or violent reaction.
“Their impulsivity isn’t necessarily going away, but that impulsivity isn’t turning into such a reaction that they are then reporting they’re engaging in violence,” Semenza said.
GLP-1 receptor agonists include medications such as Ozempic, Wegovy, Rybelsus, and Trulicity.
Since initially being prescribed for Type 2 diabetes, their use has expanded rapidly as they became FDA-approved for weight loss beginning in 2021.
Similar drugs like Mounjaro and Zepbound also act on GLP-1 receptors.
Emerging research suggests the medications may also affect dopamine signaling, cravings, reward-seeking, and stress regulation.
Those possible effects have led researchers to study GLP-1 drugs in connection with alcohol use disorder, other substance use, and compulsive behaviors.
For their study, Semenza and Thomas examined data collected in 2025 through a nationally representative survey of 7,521 U.S. adults, 821 of whom reported having used a GLP-1 medication at some point.
Of those, 597 were current users, and 224 were former users.
Respondents answered questions measuring impulsivity, alcohol consumption, and self-reported violent behavior during the previous 12 months.
The measure of violence included questions about whether respondents had hit someone who insulted them, participated in a physical fight, threatened someone with a weapon, or committed robbery.
As expected, greater impulsivity and alcohol use were both strongly associated with more reported violence.
But those associations were weaker for respondents who were currently taking a GLP-1 drug.
The researchers adjusted for a range of characteristics, including age, sex, race and ethnicity, education, income, employment, health insurance, diabetes, perceived weight, and neighborhood safety.
As a result, the impulsivity result proved more consistent.
The alcohol finding, which relied on only two questions, was less stable, becoming statistically insignificant under some alternative analyses.
The authors said that finding should be interpreted cautiously until it can be replicated with larger samples and more detailed measures.
“There is much more work to do, but the robustness and sturdiness of the impulsivity finding were striking to us,” Semenza said.
Other recent studies suggest GLP-1 medications may reduce alcohol consumption and craving.
And research has long connected alcohol to gun violence.
A 2024 study, for example, found that shortening late-night alcohol-sale hours around bars and taverns in one Baltimore neighborhood was followed by a 23 percent annual decline in violent crime.
“Two of the most well-established risk factors for violence are impulsivity and alcohol use,” said Rose Kagawa, a researcher at the University of California, Davis School of Medicine.
“If there’s something that can sort of dampen the effects of those risk factors, that’s a really powerful tool potentially.”
But neither line of research establishes that GLP-1 use reduces gun violence, and drawing that connection will require much stronger evidence, Kagawa said.
“Right now, we’re not looking at individuals over time under different conditions.”
Future research could use more robust methodologies, such as case-control or cohort studies, or, if possible, a randomized controlled trial.
Semenza was also clear that the study has limitations.
It captured respondents’ medication use and behavior at one point in time, meaning it cannot determine whether GLP-1 use caused the weaker associations.
And the survey did not identify why former users stopped taking the medication — cost, side effects, insurance coverage, or health differences.
Violence was also relatively uncommon in the sample, making it more difficult to identify statistically significant associations.

Semenza and Thomas’s study also didn’t address another major player in U.S. gun deaths: suicide.
As injuries and deaths from community violence and interpersonal gun violence have plummeted since 2022, firearm suicides — which account for the vast majority of U.S. gun deaths — have continued to tick up .
Earlier research has shown that suicide attempts often occur during brief periods of acute distress , impaired judgment, or impulsive action — the same broad behavioral processes Semenza’s study suggests GLP-1 medications might affect — while firearms make those attempts more likely to result in death compared to other means.
Other studies have identified more direct links between alcohol abuse and firearm suicide, Kagawa said.
A 2021 study she coauthored found that people who purchased a firearm after a prior conviction for driving under the influence of alcohol were at elevated risk of subsequent suicide when compared to gun buyers who had no previous alcohol-related convictions.
Another 2023 study found that as the amount of alcohol consumed increases, the probability of using a firearm as the method of suicide also increases.
Taken together, the research suggests scalable interventions targeting alcohol use may potentially reduce the suicide mortality rate.
Despite some concerns that GLP-1s might be associated with depression, an early but promising body of research has instead found associations between GLP-1 use and lower risk of suicidal ideation, attempts, or self-harm among some groups.
The possibility that GLP-1s could interrupt the progression from suicidal impulse to action remains an open research question.
Regardless, Semenza cautioned against treating medication as the solution to violence.
Poverty, unemployment, inequality, and neighborhood disadvantage remain central drivers of violence, he said.
“I would never advocate for medicalizing violence as a social problem,” he said.
Instead, he sees pharmacological research as one possible component of a broader violence-prevention strategy.
If more intensive studies confirm the results, GLP-1 medications could help researchers better understand how biological, behavioral, and environmental factors interact.
Semenza said researchers are now exploring ways to link administrative data, including Medicaid and arrest records, to examine the question more closely.
That could better establish when people were taking the medication and whether their behavior changed over time.
“Violence is preventable,” Semenza said.
“If we can find different ways and different opportunities to make that so, then I think it’s worth pushing in every direction that we can.”
