I was recently on medical leave due to a car accident. The day I returned to work, I was drug tested. After being asked to empty my pockets and my purse, i listed my prescribed medications, which included Norco, Flexeril and Xanax. I tested positive for Xanax. They stated I was under the influence, placed me on unpaid leave and called a taxi to take me home. I am sitting at home waiting for the lab to confirm the levels of what I was positive for. Can I loose my job for being positive for a prescribed benzodiazapine or any other prescription for that matter?
