How long does alcohol stay in my system for a saliva test? Depends: Alcohol has an approximate detection time of 12-24 hrs,The detection time depends on the maximum level of blood alcohol content (BAC) which can vary. One serving of alcohol can be fully absorbed in the blood stream 30 min up to 2 hrs after intake. The body metabolizes aprox 0.25 oz per hour.
Usually, alcohol would stay within your system for around 24 hours after you have had a few drinks and this would be the time period during which it would be detectable in your urine. However, there are a few special tests which can detect its presence in urine for up to 48 hours.
