False positives
Well I couldn't find too much information with various Google searches and I'm curious: what can cause false positives on a "standard" drug test (marijuana/opiates/benzos/barbs/alcohol/pcp/cocaine)? By this I mean are there legal "dietary supplements" that would flag for one of these? Anyone have any experience with a false positive they can attribute to something legal they took? I have heard that ibeuprofin can cause a false for marijuana. I ask mainly so I can avoid these things, but also out of curiosity.
