Ya, when I worked HR the tests were just another way to get rid of employees when needed. Companies suck. We would do "randoms" and the higher ups would give me their list of people they wanted a reason they could fire them for...dummy, it's not about whether or not you smoke, it's about the man having a fire-able offense on record to control you. i'm sure if they can keep you in line they all come back negative until they don't want you any more.
