EL PASO, Texas (June 8, 2026) – A new study led by researchers at The University of Texas at El Paso found that use of weight loss drugs like Ozempic and other GLP-1s is associated with a lower risk of developing alcohol, opioid, nicotine and cocaine use disorders.

The study, led by UTEP School of Pharmacy researchers Tadesse Abegaz, Ph.D., and Gabriel Frietze, Ph.D., was published in Frontiers in Psychiatry. It looked at more than 142,000 cases of patients with type 2 diabetes or obesity, of which around 20,000 were prescribed GLP-1 medications. They then examined whether GLP-1 users were more or less likely to develop substance use disorders than similar counterparts who were not on the medications.

"Our findings add to growing evidence that GLP-1 medications may influence more than appetite and blood sugar regulation," said lead author Abegaz. "These medications appear to affect brain pathways involved in reward and craving, which could help explain the lower rates of substance use disorders observed in our study."

The study found that people taking GLP-1 medications had:

74% lower odds of alcohol use disorder

69% lower odds of opioid use disorder

68% lower odds of nicotine use disorder

75% lower odds of cocaine use disorder

The team emphasizes that their findings do not establish cause and effect — GLP-1s do not specifically prevent patients from abusing substances.

“We do not support prescribing these medications for addiction treatment at this time, Frietze said. “Because this was an observational study in a specific clinical population, randomized clinical trials are needed before GLP-1 medications can be recommended for treating addiction.”

However, the team believes their results are promising and plan to continue studying GLP-1s’ effect on substance abuse.
