Random drug test for Alc/MDMA/N?
My boyfriend recently had a random drug screening at work an the control form they sent home with him is a bit unclear about what exactly he was tested for. The form stated that tests performed are "SAP 9-20 +ALC/MDMA/N". The alcohol and MDMA are obvious to me, although ridiculous they would test a legal adult for alcohol (and worrisome because he had a beer with dinner the night before), but I don't understand what the N stands for. Is this another symbol for THC or another drug?
