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.
What is this test? This test measures opiates in urine. Opiates are central nervous system depressant drugs that may be obtained by prescription or as illegal (street) drugs. This test is used for suspected overdose or abuse of opiates[1][2][3][4]. Urine opiate measurement.
