Can Weight Loss Drugs Reduce Violent Crime?

Highlights

Are weight loss drugs affecting criminal activity? There’s data suggesting that it does.

There seems to be a wide array of new observations beyond weight loss drugs that could be having an impact on criminal activity, including the decreasing percentage of young people in society, reduced use of alcohol and drugs, fewer mental health episodes, and the millions of people lost to drug overdoses, all of which may challenge our traditional thoughts about what impacts crime.

GLP drugs and their association with crime was addressed on this site in early July 2026 at Sorry Reporters-Why Crime Has No Easy Answers.

How could using weight-loss drugs influence crime?

There are endless theories and explanations for criminal behavior. When I taught criminology at a state university, I warned students that criminological theories were endless and that few would work their way into today’s evolving understanding of criminality.

Today, we have speculation that GLP weight loss drugs have an impact on drug and alcohol use and impulsiveness; all are connected (correlated) with violence and overall criminal activity.

Background

When I was the senior specialist for crime prevention for the Department of Justice’s clearinghouse, the question was whether criminals planned their activities or mostly reacted to unexpected opportunities.

The consensus was that most criminal activity was unplanned and impulsive. Earlier research (within select cities) stated that most arrested people tested positive for drugs or alcohol, which is known to affect behaviour.

At the time, the belief was that most crime could be stopped by citizen precautions, the rationale behind McGruff the Crime Dog and his “Take A Bite Out of Crime” slogan.

I was the person at the National Crime Prevention Council who provided the national advertising team with research and statistics for the award-winning McGruff national advertising campaign.

Locking doors and windows meant fewer burglaries. Walking or being with other people reduced the risk of violent crime. Home security precautions worked, according to surveys of offenders.

The heart of the campaign was the impulsive nature of criminality, probably fueled by substance abuse.

I interviewed a criminal in prison who stated that he battered and sexually assaulted a lone woman for coming onto his street. “If she was that stupid to drive on my street and ask for directions,” he said, “she deserved to get what she got.”

He was high on drugs at the time.

Biology and Crime: Can Our Bodies Influence Criminal Behavior?

For more than a century, criminologists have explored whether biology plays a role in criminal behavior.  Biological factors may increase or decrease a person’s risk.

Some theories focus on genetics, suggesting that traits such as impulsivity or aggression may make some people more vulnerable to criminal behavior. 

New Research Raises Intriguing Questions About Impulse Control, Addiction, and Public Safety

Millions of Americans take medications such as Ozempic, Wegovy, Mounjaro, and Zepbound to treat diabetes or lose weight. Doctors have already discovered that these drugs do much more than reduce appetite. They lower the risk of heart disease, improve blood sugar, and may help protect the kidneys.

Now researchers are exploring another surprising possibility: Could these medications also reduce impulsive behavior and reduce the craving for drugs and alcohol, and perhaps, over time, some forms of violent crime?

The answer today is that we don’t know. But new research suggests the question is worth studying.

Glucagon-Like Peptide-1 Receptor Agonist Use and Violent Crime Among US Adults, The Journal of Criminology

A study published in the Journal of Criminology specifically explored whether GLP-1 use was associated with violent crime.

It examined the health records of more than two million people with diabetes taking GLP-1 receptor agonists, the class of medications that includes Ozempic and similar drugs.

Rather than focusing on weight loss, researchers looked at 175 different health outcomes.

Among their findings, people taking these medications were less likely to develop several conditions, including:

• Alcohol use disorders.
• Drug use disorders.
• Suicidal thoughts and self-harm.
• Some neurological and psychiatric conditions.

Where Crime Enters the Picture

The study never examined violent crime. It never asked whether people taking GLP-1 medications committed fewer assaults, robberies, or homicides.

Instead, the criminal justice connection comes from what researchers already know about impulsive behavior.

For decades, criminologists have found that poor impulse control is one of the strongest predictors of violent offending. People who act before thinking are generally more likely to become involved in assaults, domestic violence, road rage incidents, and other aggressive acts.

Scientists now believe GLP-1 medications affect parts of the brain involved in reward, cravings, decision-making, and self-control.

If future studies confirm that these drugs improve impulse control, they could eventually have implications that extend well beyond medicine.

Alcohol May Be the Bigger Story

The strongest criminal justice connection may actually involve alcohol.

Alcohol contributes to a significant share of violent crime in the United States, including assaults, domestic violence, sexual assaults, and many homicides. It also plays a major role in impaired driving and disorderly conduct arrests.

If GLP-1 medications reduce alcohol cravings or help people drink less—as several recent studies suggest—they could indirectly reduce crimes associated with excessive alcohol use.

That possibility has attracted growing attention from both medical researchers and criminologists.

Medical research is opening another possible avenue: improving brain health and reducing the biological factors that contribute to impulsive behavior and addiction.

If medications can successfully reduce substance abuse or improve self-control, they could eventually become part of a broader strategy to prevent crimes before they occur.

That idea remains speculative, but it reflects a growing understanding that crime is influenced by a complex mix of biological, psychological, and social factors.

Stanford: GLP-1s Show Promise For Opioid, Alcohol, And Nicotine Addiction

Early studies suggest that GLP-1s may be effective in treating opioid, alcohol, and nicotine addiction. In one small study of patients with opioid use disorder, a GLP-1 medication reduced their cravings for opioids by 40% over three weeks. Another study found that people with opioid or alcohol use disorder who took GLP-1s had a 40% lower rate of opioid overdose and a 50% lower rate of alcohol intoxication than people who weren’t on the medications. 

Conclusions

Reported crime is decreasing a tad in 2023 and 2024, per the FBI. Cities are reporting more substantial reductions. Some say that the decrease may be more meaningful in 2025 (that data will be out soon).

Having said this, the great majority of crime is not reported, and the USDOJ’s National Crime Victimization Survey has shown large increases in rates of violent crime (44 percent) in recent years. Per Gallup, there is more fraud and identity theft than all FBI-reported crimes.

Thus, the study of crime data is complex. You could make a case for increasing and decreasing crime using Gallup and USDOJ data.

But there seems to be good news in terms of alcohol consumption, which is heavily connected to violence. The rate of younger people in America is decreasing, and criminology 101 suggests that crime is connected to the number and percentage of young people within society. Mental health problems and drug and alcohol use by younger people are decreasing.

Another possible explanation for fewer reported crimes is that exceptionally high overdose mortality among chronic substance users (the toll approaches two million deaths over time) may have had some effect on crime. 

It is reasonable to ask whether overdose mortality removed enough high-rate offenders from the community to influence crime statistics. To date, however, this possibility has received little direct empirical study. 

Now we have a series of weight loss drugs where research suggests an impact on impulsive behavior and drug and alcohol use. There are dozens of articles documenting the impact of weight loss drugs.

“If” reported crime is decreasing, there may be reasons we haven’t considered. 

For now, the science supports cautious optimism as to the impact of weight loss drugs, not sweeping conclusions. The research raises an intriguing question that deserves further study, but it does not yet fully justify claims that weight-loss drugs reduce violence.
