I know that trails are underway to examine the impact of GLP-1 agonists on AUD (Alcohol use disorder). I asked Claude about trails for addictions more broadly and it gave me the info below;
Yes, quite actively — it's become one of the more exciting areas of GLP-1 research.Yes, quite actively — it's become one of the more exciting areas of GLP-1 research. Trials are underway or recently completed looking at:
Alcohol — probably the most advanced, with Novo Nordisk running specific trials on semaglutide for alcohol use disorder
Opioids — there are trials looking at whether GLP-1 agonists reduce cravings and relapse rates, with some promising early signals
Cocaine and stimulants — earlier stage but active research, particularly in the US where the stimulant addiction crisis is significant
Nicotine/smoking — some observational data suggesting people on GLP-1s spontaneously smoke less, and trials are following up on that
Gambling and behavioural addictions — very early stage but researchers are interested given the reward pathway mechanism
The underlying theory across all of these is the same — GLP-1 receptors in the brain's dopamine reward circuitry appear to dampen the "want" signal that drives addictive behaviour, not just for food but for anything that triggers that system. If that holds up it would be quite a profound finding, essentially suggesting these drugs are modulating reward-seeking behaviour generally rather than just appetite specifically.
The challenge is that addiction trials are slower and harder to run than weight loss trials — outcomes are less easy to measure and confounders are everywhere. But given the scale of the addiction crisis globally, there's a lot of research money going in. Worth watching over the next 3-5 years.
I need to stop taking MJ because I was not overweight when I started and I am now approaching the lower end of the healthy BMI band. I also have a history of ED (a long time ago) but I can see that being on this drug is not very good for me in that respect. There is a drug called Naltrexone which works differently to the GLP-1s but is a pharmacological 'solution' to AUD so I might investigate that if I struggle to manage my alcohol consumption when I come off MJ.
