A massive study of more than 600,000 U.S. veterans suggests that popular GLP-1 drugs such as semaglutide may do far more than help with diabetes and weight loss—they could also fight addiction itself. Researchers found that people taking these medications were less likely to develop substance use disorders involving alcohol, nicotine, cannabis, cocaine, opioids, and other drugs, while those already struggling with addiction experienced fewer overdoses, hospitalizations, emergency visits, and drug-related deaths.

A recent trial is the latest to suggest that GLP-1s aren't just for treating diabetes and obesity.
