Health question can one pill over your perscription( narcotics) amount be detected in a urine test?

All narcotics show up on urine tests. It doesn't say how much of the narcotic that you took. If you have a prescription, then don't worry about taking narcotics, if you are taking someone else's prescription narcotics and you have a urine test coming up, now is the time to worry and clean your system out!
