Alcohol can be detected from 12 to 24 hours in the breath, as well as in saliva. And when tested in the hair, especially at the root, alcohol can be detected up to 90 days after a person has stopped drinking. The percentage of alcohol that is in a person’s bloodstream is known as the Blood Alcohol Concentration (BAC). BAC is usually expressed as a percentage of ethanol that is present in the blood in units of mass of alcohol per volume. For most people, one ounce of alcohol will produce a .015% blood-alcohol concentration. This means someone with a .015% blood-alcohol level will have little to no alcohol in their bloodstream after 10 hours have passed.
It’s important to note that the more you drink, the longer alcohol stays in the system. There’s a difference between a blood alcohol content test, which measures how much alcohol is in your system, and a test designed simply to determine if there was alcohol in your system. BAC tests can be unreliable if they aren’t performed correctly, and many people attempt to influence the test by trying to delay or contaminate it.

However, hair tests cannot determine a person’s blood alcohol content. It can only determine if the person has been drinking within the last 90 days. Once swallowed, alcohol enters the digestive system and travels to the stomach and small intestine.
