I was given a drug test for a promontion at work which resulted in a false positive. I tried to resolve this though escreen, but was treated very rudely and told that the over the counter drugs I was using for my flu would not result in a positive test result. I had not used pot in nearly a year since I moved from Colorado and had passed a mouth swab test for Safeway just a few months prior. This not only cost me my promotion but also my job.
