Why do women reach a higher bac before men?

Answer 1

Women of the same height and weight as men tend to become intoxicated faster when consuming the same amount of alcohol over the same length of time. That's because they have a higher proportion of fat (which doesn't absorb alcohol, thus concentrating it in the blood), less of a stomach enzyme (dehydrogenase) that helps metabolize alcohol, and because of the action of female hormones.
