I recently took a drug test for a job. I tested positive for opiates in my urine. I do not and have never taken drugs of any sort other than alcohol. I dont take any prescription drugs, how is it possible that this happened. I hade consumed some beer about12 hours before the test.
Will methadone show up as an opiate in a urine drug test? If you take a 5 Panel Drug Screen, it will be Negative for  Methadone. Methadone is synthetic and does not cause a positive  Opiate result. However, the 10 and 12 panel drugâ¦ screens do  specifically test for Methadone as one of the 10 or 12 types of  drugs.
