Read here and you'll see that if they do a hair drug test, meds like fentanyl will stay in the hair for 90 days to even six months. http://www.answers.com/topic/drug-test...
If you have a prescription for fentanyl, don't worry. Just keep acopy of a doctor's note saying it's a legitimate prescription.
If you are taking it without a prescription....worry.
