How Long Does Alcohol Stay in Your System?

In late February, a school bus driver was arrested and charged with driving under the influence (DUI) after he confessed to police officers of consuming three-quarters of a gallon of bourbon the previous night. To prove it, he supplied a breath sample of .18 – more than twice the legal limit for driving.

In this article, we’ll talk about just how long it takes for alcohol to leave your system.

How Alcohol Enters the Bloodstream

Merely 30 seconds after you consume it, alcohol will be introduced into your bloodstream. While about 20% of it will be carried through your body and eventually to the brain through your blood vessels, the remaining 80% will go through your digestive system as it makes its way through your bloodstream after its absorbed by the small intestines.

Before it’s expelled from the body through sweating, breathing and urination, most of the alcohol will find its way to the liver, where it will be metabolized.

According to medical data, 1 ounce of alcohol should be metabolized by your liver per hour.

How Long Before Alcohol Leaves Your System?

While there are a few variables to consider (how much was consumed, how strong the drinks were, whether or not you had food), our livers should be able to metabolize alcohol at about the same rate – about 0.015 on the blood alcohol content (BAC) scale.

So, if you have a BAC of 0.030, you’d need about 2 hours for the alcohol to make its way from your system.

For the school bus driver in the case above who had a BAC of .18, he probably needed about 12 hours of downtime for the alcohol to leave his system.
