Have you ever noticed that men tend to drink more alcohol than women? Have you ever wondered why women appear to be more affected by the same amount of alcohol? Could it be as simple as differences in physical size? Check out the information below and the Blood Alcohol Concentration Charts.

Generally, the same amount of alcohol consumed over the same period of time will result in a higher BAC for women than for men. This effect is related to differences in average body water content and to the ability to break down alcohol in the stomach.
