I recently took a pre employment DOT alcohol and drug screen. 7 days later i received a very hard to hear phone call from florida . The woman said, i think, in esscence that i had tested positive for a drug . I stated i couldnt hear her well and she replied she couldnt hear me either very well. She put someone on phone saying that he was a doctor and i had failed a test. When I spoke he said he couldnt hear me well and gave me back to lady saying he needed a translator( a joke i guess). She asked if i had any medical reason. I told her i had brought a list of my medicines to the testing site, but the site had no interest in loooking at them. They didnt take my list. I explained ti lady in Florida, i do not take any illegak drugs. Must be a mistake with sample, or was it one of the herbal products i take, or maybe even somene had put something in my food. All i know is that I didn't take an illicit drug. She said they would call back in a couple days. They never did. A few weeks later i got an email on an account i no longer use. Saying that i now had a violation in the FMCSA Clearinghouse. . I have driven 37 yesrs as truck driver, countless negative test results from DOT drug screens. 3 million safe miles. And I would take a substance just before a planned drug screen? This ruins my career, my family. Ill lose my home. .. removal of violation from FMCSA Clearinghouse is my wish. Sincerely. D. M.
