Absorption of Alcohol for Drunk Driving

By: Wallin & Klarich

Alcohol is rapidly absorbed once it reaches the small intestine. Anything that delays the stomach from emptying its contents into the small intestine will slow the rate of alcohol absorption. Generally, the most rapid absorption takes place when alcohol is consumed on an empty stomach. Diluted drinks take somewhat longer to absorb. In addition, alcoholic beverages containing ingredients that require digestion, such as carbonated beverages, may also slow absorption. Absorption may also be affected by emotional state, shock and medications that impact stomach function and the general condition of the gastrointestinal tract.


One of the most important factors affecting absorptions is the presence of food in the stomach simultaneous with alcohol. Food requires digestion and any alcohol trapped in food particles will take longer to be absorbed. The extent of the effect depends on the amount and type of food.

Absorption rates and times vary considerably between subjects (even within the same subject at different times under similar conditions). This is very important to discuss with your DUI attorney. Based upon your absorption of alcohol, your blood alcohol results may require further analysis before being deemed valid.
