DUI Impairment Chart - Blood Alcohol Levels
A
lcohol is metabolized by the body at a rate of approximately one drink per hour.
Scientific research shows that women metabolize alcohol more slowly than men. Therefore, a woman with an equivalent body weight to a man who consumes the same amount of alcohol consumption over an equal period of time may have a higher blood alcohol content than a male with the exact same criteria.
