Tolerance

People who regularly become intoxicated, or who regularly consume large amounts of alcohol, may develop a tolerance to alcohol. Such a drinker may require a higher BAC to exhibit the same symptoms that an average social drinker exhibits at a lower BAC. Conversely, a person who drinks alcohol infrequently may show intoxication symptoms at lower BACs than the average social drinker, and is said to have a low tolerance to alcohol.
