The amount of alcohol in the blood reaches its highest level about an hour after drinking. But food in the stomach may increase the amount of time it takes for the blood alcohol to reach its highest level. About $90\%$ of alcohol is broken down in the liver. The rest of it is passed out of the body in urine and your exhaled breath. Symptoms of alcohol intoxication include confusion, lack of coordination, unsteadiness that makes it hard to stand or walk, or erratic or unsafe driving. Dope test is not related to alcohol.
