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.
Opiates are one of the SAMHSA-5. The five drugs tested for in the standard NIDA approved drug test. The standard tests are a one step rapid qualitative immunoassay for the detection of opiate and opiate metabolites in urine.
