In a fasting individual, it is generally agreed that 20% to 25% In a fasting individual, it is generally agreed that 20% to 25% of a dose of alcohol is absorbed from the stomach and 75% to of a dose of alcohol is absorbed from the stomach and 75% to 80% is absorbed from the small intestine. Thus, in fasting 80% is absorbed from the small intestine. Thus, in fasting people, peak BACs are achieved in 0.5 to 2.0 hours; while in people, peak BACs are achieved in 0.5 to 2.0 hours; while in non-fasting people, peak alcohol BACs are achieved in 1.0 to non-fasting people, peak alcohol BACs are achieved in 1.0 to 6.0 hours. 6.0 hours.
While alcohol will be absorbed from the stomach, it is a While alcohol will be absorbed from the stomach, it is a slower and less efficient transition. Because alcohol is slower and less efficient transition. Because alcohol is absorbed most efficiently in the small intestine, the ingestion absorbed most efficiently in the small intestine, the ingestion of food can slow down the absorption of alcohol by keeping of food can slow down the absorption of alcohol by keeping the alcohol in the stomach longer the alcohol in the stomach longer
