How long does alcohol stay in your urine? Alcohol typically stays in the body for up to 24 hours after consumption, but specialized tests may be able to detect traces of alcohol even past that timeframe. For example, the EtG Urine Alcohol Test can detect urine in the body up to 80 hours after drinking.
Alcohol itself stays in your system for 1-1.5 hours for each drink you take, plus approximately 1 hour delay for the initial drink -- this is when it's detectable in breath and blood, and when it will affect you. It then stays in your urine for another hour or so, where it's detectable in a urine test.
