I weigh 130 pounds and I have had just a few drinks of alcohol, how long will it take to be out of my system for a urine test?

Count the number of drinks that you had and multiply by 2. That is a safe way to determine maximum amount of time for alcohol clearance.

If the test is checking for EtG/EtS that extends detection time considerably. Would need to know gender, height, weight, number and type of drinks consumed and the time span from start to finish of drinking.
