What percentage of the alcohol consumed is absorbed by the small intestine?

The percentage of alcohol consumed that is absorbed by the small intestine is around 80%. This is because the small intestine has a large surface area and rich blood supply, making it highly effective for the absorption of substances, including alcohol. While some alcohol is absorbed in the stomach, the majority is taken up in the small intestine, where it enters the bloodstream more rapidly. This rapid absorption contributes to the effects of alcohol felt shortly after consumption. Understanding this process is essential for comprehending the pharmacokinetics of alcohol and its effects on the body during a Standardized Field Sobriety Test (SFST).
