Researchers in France and Belgium reviewed 26 previous studies published between 1974 and June 2018 that explored the effects of CBD on animal subjects dosed with ethanol. They found several studies that showed CBD can reduce alcohol consumption.
Not only does cannabidiol appear to “facilitate drinking reduction,” the paper’s authors write, but research also shows the compound “may provide idiosyncratic protection to the liver and brain, which could reduce the development and impact of alcohol-related liver disease and alcohol-related brain injury.”
The review, which is awaiting publication in the journal Frontiers in Pharmacology, offers a comprehensive look at how promising the data is so far regarding the effectiveness of CBD on alcohol use disorders (AUD) in animal models. The authors, however, also call for human clinical trials, of which none have been published to date, to “pave the way for testing new harm reduction approaches in AUD.”
