It would raise a red flag. But the testing company would call you to verify the reason. So long as you have a valid prescription for it. You should be good to go.
They ask for all prescriptions before the test and depending on the amount still in your urine how long ago you took it. Codeine is a amphetamine so only stays in your system for 30 days you'll be fine.
so they only do a wiz quiz i am very curious i don't want to go out there and get sent home over something stupid like a pain pill for a tooth i got pulled i don't even know how long that stays in your system,any info would be great .....:smt066
