How Long Does Alcohol Stay on Your Breath?
People often ask how long does alcohol stay on your breath because the answer affects decisions like driving and workplace testing. A related concern is how long does alcohol stay in your system when a test is possible the next day. Alcohol does not simply sit in the mouth. Ethanol moves from the stomach and intestines into the bloodstream, then reaches the lungs. As blood passes through the lungs, some ethanol transfers into the air that is exhaled, which is why breath alcohol testing works. The key point is that “alcohol on your breath” can mean two different things, and those two timelines do not always match.
