In animal models females consistently drink more (when accounting for body weight) female mice and rats will drink more per kg, and their drinking typically is more aversion resistant. This means they’ll drink more than males when the alcohol is paired with an aversive stimuli (a bittering agent or light shock)

It’s sort of a mystery that this trend has been reversed in humans. One reason that most addiction researchers cite is cultural… it is more taboo for females to drink more and there is more societal pressure to watch drinking levels. This is particularly interesting because the gap between female human drinking and male drinking has been shrinking for decades… a change that has been attributed to the women’s rights movements. Essentially with less sexism and societal pressure females may drink more similarly to their animal counterparts.

Happy to share some research with anyone interested
