There’s a bar in Baltimore, Maryland, that very few people get to enter. It has a cocktail station, beer taps and shelves stacked with spirits. But only scientists or drug-trial volunteers ever visit, because this bar is actually a research laboratory. Here, in a small room at the US National Institutes of Health (NIH), scientists are harnessing the taproom ambience to study whether blockbuster anti-obesity drugs might also curb alcohol cravings.
Evidence is mounting that they could. Animal studies and analyses of electronic health records suggest that the latest wave of weight-loss drugs — known as glucagon-like peptide 1 (GLP-1) receptor agonists — cut many kinds of craving or addiction, from alcohol to tobacco use.
