It's pretty well known that Advil can give you false positives on the EMIT test. Recently I've been taking a lot of Advil for various cuts and bruises since Aspirins been too hard on the stomach. My question is, is the buildup of Advil in my system over a week's span going to jeapordize any upcoming UA I may be taking? I know they do the GC/MS confirmation to make sure, but still, I don't want any hassle. So the chemicals in Advil that cause you to get a false positive, how long before they are cleared out of your system? I hope this isn't a fat soluble thing like THC...
