List of substances that cause false positives on drug tests

I figured this might be useful, mostly because a false positive at best usually means they'll make you test again and at worst means you won't get whatever job you're applying for. Things like poppyseeds --> heroin aren't surprising, but you might jump at aleve (naproxen) ---> cannabis and amoxicillin ---> cocaine. Some of the refs are very good (anything that says ref 29 for example, it's a handbook from a drug test maker) while others are not so much (e.g the one off the phentermine forum). I'd still avoid these in the lead-up to a test, I guess.

The Vicks stuff is interesting, because it actually contains methamphetamine, but only the entirely inactive isomer laevomethamphetamine. Drug tests, apparently, are achiral.
