I have custody of my son and I have had to take random drug test at my home. Out of almost 10 months I have failed 2 times for alcohol. Both times I had a monster drink before the testing. It is a urine test and also some kind of card looking thing they dip in the urine. The instant card thing showed nothing positive. But, the urine they send off came back as a weak positive. Can this drink have anything to do with it? Because I have no other idea of how it could be positive for alcohol, considering I do not drink.
