GLP-1 Drugs and Addiction

The rise of weight-loss medications like Ozempic and Wegovy has shifted how the medical community treats obesity and diabetes. However, patients and researchers are noticing an unexpected benefit beyond the scale. Emerging evidence suggests that GLP-1 agonists, the class of drugs used for weight management, may effectively curb cravings for alcohol, opioids, and nicotine. This potential dual benefit could revolutionize addiction treatment.

The Science Behind the Suppression

To understand why a diabetes drug stops someone from craving a glass of wine or a cigarette, you have to look at the brain. Drugs like semaglutide (the active ingredient in Ozempic and Wegovy) mimic a hormone called glucagon-like peptide-1.

While this hormone primarily helps the pancreas release insulin and tells the stomach to empty more slowly, its receptors are also found in the brain. Specifically, they reside in the mesolimbic system. This area is often called the “reward center” of the brain. It regulates dopamine, the chemical driver behind pleasure and addiction.

When you eat a sugary donut, drink alcohol, or take opioids, your brain releases a surge of dopamine. GLP-1 drugs appear to dampen this dopamine release. Essentially, they lower the volume on the “reward” signal. Patients report that the buzz from alcohol feels less intense, or that the thought of using substances simply becomes less intrusive.

Analyzing the Data on Opioids and Alcohol

The link between GLP-1s and reduced substance use is not just anecdotal. A major study published in October 2024 involving researchers from Loyola University Chicago provided concrete data. The researchers analyzed electronic health records of over 500,000 patients with a history of opioid use disorder (OUD).

The results were statistically significant:

  • Patients with OUD who had a prescription for GLP-1 drugs had a 40% lower rate of opioid overdose compared to those not taking the medication.
  • The study also looked at alcohol use disorder (AUD). It found that patients on GLP-1s had a 50% lower rate of alcohol intoxication events compared to the control group.

This data supports earlier animal studies. For years, researchers observed that rodents given GLP-1 analogs lost interest in alcohol and cocaine. Now, real-world human data is confirming those biological mechanisms.

Specific Drugs Showing Promise

Not all GLP-1 drugs are the same, but several are showing similar effects on addictive behaviors.

Semaglutide (Ozempic, Wegovy)

This is the most widely discussed drug in this category. Manufactured by Novo Nordisk, it is currently FDA-approved for Type 2 diabetes and obesity. The anecdotal reports of “Ozempic face” are now joined by reports of patients spontaneously quitting smoking or leaving half a glass of wine on the table because they lost interest.

Tirzepatide (Mounjaro, Zepbound)

Produced by Eli Lilly, this drug acts on both GLP-1 and GIP receptors. Because it has a dual mechanism, some researchers hypothesize it might be even more potent in altering reward pathways. Clinical trials are currently underway to see if its efficacy in weight loss translates to higher efficacy in addiction cessation.

Liraglutide (Saxenda, Victoza)

This is an older, daily injection. While less potent for weight loss than semaglutide, earlier studies indicated it could reduce alcohol intake in heavy drinkers.

Current Clinical Trials and Future Outlook

While the retrospective data is promising, these drugs are not yet FDA-approved for treating addiction. To change that, rigorous randomized clinical trials (RCTs) are necessary.

Currently, several trials are recruiting or underway:

  • Christian Hendershot at the University of North Carolina at Chapel Hill is leading trials specifically looking at semaglutide’s ability to reduce alcohol intake and smoking.
  • Alexandra DiFeliceantonio at Virginia Tech is studying how these drugs alter food and drug rewards in the brain.

If these trials are successful, we could see label expansions for these drugs within the next three to five years. This would allow insurance companies to cover Ozempic or Mounjaro specifically for addiction treatment, drastically increasing access.

Barriers to Treatment

Despite the excitement, there are significant hurdles. The primary issue is cost and availability.

  • Price: Without insurance coverage, drugs like Wegovy can cost between \(900 and \)1,350 per month. Most insurance plans only cover them for diabetes or strict obesity diagnoses.
  • Supply: Shortages have plagued the market since 2022. Adding millions of patients seeking addiction treatment could strain the supply chain further.
  • Side Effects: These are not risk-free medications. Common side effects include nausea, vomiting, and more serious risks like gastroparesis (stomach paralysis) or pancreatitis.

Conclusion

The potential for GLP-1 agonists to treat addiction represents a massive shift in psychiatry. For decades, treatments for alcoholism and opioid dependence have been limited and often have low adherence rates. If a weekly injection can reduce cravings for food, drugs, and alcohol simultaneously, it offers a comprehensive approach to health that modern medicine has rarely seen.

Frequently Asked Questions

Can I get a prescription for Ozempic to help me stop drinking? Technically, yes, but it would be an “off-label” prescription. This means a doctor can legally prescribe it for addiction if they believe it will help, but insurance is unlikely to cover the cost. You would likely have to pay the full retail price, which exceeds $900 monthly.

Does this work for behavioral addictions like gambling? There is anecdotal evidence suggesting it might. Because GLP-1 drugs target the dopamine reward system, which drives gambling and shopping addictions, some patients report a decrease in these impulses. However, scientific studies specifically focusing on gambling are still in very early stages compared to substance use studies.

Are there other medications for alcohol use disorder? Yes. FDA-approved medications include Naltrexone, Acamprosate, and Disulfiram. Naltrexone works somewhat similarly by blocking the euphoric effects of alcohol, but many patients find the side effects of GLP-1s more manageable or prefer the weekly injection schedule over daily pills.

Will I lose interest in all pleasures, like hobbies or socializing? This is a condition known as anhedonia. While some patients report a general flattening of excitement, most studies suggest the drug specifically targets the “craving” and “seeking” drive rather than the enjoyment of life itself. However, this is a side effect researchers are monitoring closely in ongoing clinical trials.
