I am confused as to the answers I see regarding timeframes for detection. If undergoing drug and alcohol testing is it the answer that a drink is not detectible after 2 hrs or so or that it can take up to 30-36 hrs to not be detected? I weigh 210 pounds and typically have no more than 2 3.2 beers and a glass of wine. How long before it is not going to cause a detectible trace?

If you do what you are supposed to be doing then you would always pass your tests without worrying and your stress levels would be lower.
Personally I think they should be giving 24 hour notices to show up at a test center....more people would have to do what they were supposed to be doing in the first place.

The purpose of this site is not to assist you in learning how to cheat on required alcohol and drug tests. Which is the apparent intent of your question.

Nobody volunteers for drug or alcohol testing and its only done to stay out of jail, or to keep a job. So there are consequences to failing so why take that kind of a chance on losing a job, or your freedom on a some what arbitrary set of factors?

I mean if that beer or wine or joint is more important than what's at stake what's the worry?
