A class of medications best known for treating diabetes and obesity may also reduce the risk of addiction \u2013 and help people who already have one, a new study shows<\/a>. <\/p>\n

Semaglutide (also known as Ozempic), liraglutide and tirzepatide (Wegovy) belong to a class of drugs called GLP-1 (glucagon-like peptide-1) receptor agonists. These mimic a hormone involved in regulating blood sugar and appetite.<\/p>\n

Interest in GLP-1s for addiction<\/a> has grown in the past decade, as some people prescribed them for diabetes or weight loss noticed they were drinking less alcohol or smoking less. <\/p>\n

Animal studies<\/a> suggested these drugs might reduce cravings and lower the risk of relapse. Large studies using health records or administrative data<\/a> hinted at similar patterns.<\/p>\n

This new study<\/a>, published today in the BMJ, found starting a GLP-1 drug was linked with a 14% overall reduced risk of developing new substance use disorders, including alcohol, cannabis, cocaine, nicotine and opioids. Among people with an existing substance use disorder, taking a GLP-1 was associated with a 26% reduction in substance-related hospital admissions.<\/p>\n

What did the researchers do?<\/p>\n

Researchers examined electronic health records from more than 600,000 veterans with diabetes who were treated through the United States Department of Veterans Affairs. <\/p>\n

Researchers compared those newly prescribed a GLP-1 with those started on a different class of diabetes medication called SGLT2 inhibitors (including empagliflozin and dapagliflozin) \u2013 a well-established treatment used as a comparison point.<\/p>\n

The study followed participants for up to three years, asking two questions:<\/p>\n

among people with no prior addiction diagnosis, were those on GLP-1 drugs less likely to develop one? <\/p>\n

among people who already had a substance use disorder, were those on GLP-1 drugs less likely to experience serious harms, such as hospitalisation, overdose, emergency department visits, or death?<\/p>\n

The researchers used a method called \u201ctarget trial emulation,\u201d which structures an observational study to resemble a randomised controlled trial as closely as possible. <\/p>\n

In a randomised controlled trial, participants are randomly assigned to receive either the drug being tested or a comparison treatment. The two groups should be similar in every way except for the treatment they receive. If one group does better, we can be confident the drug caused it.<\/p>\n

Observational studies work differently. No matter how carefully researchers try to account for differences such as weight, age and other health conditions, there is always the possibility that some unmeasured factor explains the results. <\/p>\n

The target trial emulation design used here is among the best available approaches for observational data, but it cannot eliminate this problem. It can tell us that something is associated with better outcomes; it cannot prove that the drug caused those outcomes.<\/p>\n

What did they find?<\/p>\n

With that caveat in mind, the results were notable. Among people without a prior substance use disorder, those on GLP-1 drugs were less likely to develop one across every substance category examined: <\/p>\n

alcohol, an 18% lower risk
\ncannabis, 14% lower
\ncocaine, 20% lower
\nnicotine, 20% lower
\nopioids, 25% lower.<\/p>\n

This amounted to roughly 1\u20136 fewer cases per 1,000 people over three years.<\/p>\n

For those who already had a substance use disorder, those prescribed GLP-1 drugs had better outcomes across every measure: <\/p>\n

31% fewer emergency department visits related to their substance use disorder
\n26% fewer hospital admissions
\na 39% reduction in overdoses
\na 25% reduction in suicidal thoughts or attempts
\n50% fewer deaths.<\/p>\n

This amounted to around 1\u201310 fewer events per 1,000 people over three years.<\/p>\n

That these patterns held across multiple substances and multiple outcomes makes them harder to dismiss. <\/p>\n

But they remain associations, not proof. The ongoing randomised trials will be essential for determining whether GLP-1 drugs genuinely cause these benefits, or whether something else is at work.<\/p>\n

But these results might not apply to everyone<\/p>\n

The cohort was 90% male with an average age of 65, so findings may not extend to women, younger people, or those without type 2 diabetes. <\/p>\n

The group also had significant health complexity. More than half (57%) were current or former smokers, over 40% had high cholesterol, and many had additional conditions including high blood pressure, heart disease and heart failure. <\/p>\n

Mental health conditions were also common \u2013 more than 18% had post-traumatic stress disorder (PTSD), over 10% had depression and over 10% had anxiety. <\/p>\n

We also don\u2019t know whether participants were receiving any treatment for their substance use disorder, which could itself influence outcomes.<\/p>\n

The bigger picture<\/p>\n

Perhaps the most important takeaway isn\u2019t about GLP-1 drugs at all. Substance use disorders are highly treatable. <\/p>\n

Effective, evidence-based medications already exist \u2013 naltrexone and acamprosate for alcohol, methadone and buprenorphine for opioids \u2013 alongside a wide range of psychological therapies. <\/p>\n

These treatments are safe<\/a> and effective<\/a>, yet only a small fraction of people who could benefit from them ever receive them. An estimated 3% of people with alcohol use disorder<\/a> are ever prescribed effective medication.<\/p>\n

The biggest barrier isn\u2019t availability: it\u2019s stigma, shame, fear of judgment and discrimination. Society still views addiction as a moral failing rather than a health condition.<\/p>\n

For people living with a substance use disorder, this research on GLP-1s is encouraging but the more immediate message is that effective treatments are already available.<\/p>\n","protected":false},"excerpt":{"rendered":"A class of medications best known for treating diabetes and obesity may also reduce the risk of addiction…\n","protected":false},"author":2,"featured_media":458550,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[42],"tags":[102,6591,56,54,55],"class_list":["post-458549","post","type-post","status-publish","format-standard","has-post-thumbnail","category-medication","tag-health","tag-medication","tag-uk","tag-united-kingdom","tag-unitedkingdom"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/458549","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/comments?post=458549"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/458549\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media\/458550"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media?parent=458549"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/categories?post=458549"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/tags?post=458549"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
