San Diego, CA: CBD administration reduces alcohol intake and alcohol-associated withdrawal symptoms in rodents, according to preclinical data published in the journal Nature: Neuropsychopharmacology.
Investigators affiliated with the University of California at San Diego assessed the effects of CBD dosing on alcohol-dependent rats. They reported that CBD mitigated alcohol intake, prevented alcohol-induced damage to the brain, and attenuated relapse-like behaviors.
“The present study demonstrates that chronic administration of cannabidiol attenuates both behavioral and neurobiological manifestations of alcohol dependence in rodent models,” authors concluded. “Specifically, CBD reduced alcohol intake and withdrawal symptoms, lowered relapse-like behaviors, normalized neuronal excitability in the basolateral amygdala (BLA), and prevented alcohol-induced neurodegeneration in striatal regions associated with reward and habit formation. … These results underscore CBD’s potential therapeutic utility for alcohol use disorder (AUD) and provide mechanistic insights into its actions.”
Placebo-controlled clinical data published earlier this year concluded that the oral administration of 800 mg of synthetic CBD significantly reduces subjects’ cravings for alcohol. A 2021 observational study determined that the consumption of CBD-dominant cannabis is associated with reductions in subjects’ alcohol intake. The authors of that study reported that participants who ingested CBD-dominant cannabis during the trial period “drank fewer drinks per drinking day, had fewer alcohol use days, and fewer alcohol and cannabis co-use days” compared with those who did not.
According to 2024 survey data, 60 percent of cannabis consumers say that using cannabis leads to less alcohol consumption.
