I just found out yesterday that because of a dui, I have to submit to an alcohol test program on Friday. I do not have an alcohol problem but I did have 3 beer on my birthday Tuesday. How long does alcohol stay in your system?

Drug test - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/Drug_test)

Time it takes depend on size of person, type of alcohol, and also if you've already had food in your stomach. For your average consumption, 9-12 hrs to play it safe

I am concerned about the accuracy of your information.Could you please provide a link to your information?

How are you concerned with my information? I "ONLY" said you could use the 9-12 hrs as a rule of thumb. I'm not going to get into any detail with my profession, but if you or anyone else does not believe it or thinks otherwise that is fine.
