What over the counter drugs show up as meth in your urine?

Are you being tested for Meth? Or just a standard drug test? (Like for work or whatever) Unless you are being tested exclusively for a specific chemical in your urine, there won't be sirens and lights flashing in the lab with your name blinking this person is on METH! hahaha But if you do use, and you don't even know the garbage that goes into making that crap, now would be a perfect time to do some research on the net.
