I live in the mid-west and am a union construction worker. We are subject to random drug tests all the time. I always have kept a quick fix kit or "the one" kit handy to jump through their hoops. My buddy got a ramdom the other day so he took his kit and did his thing. The nurse took the cup from him and gave it a little shake and frickin smelled it. The nurse said he would not accept this sample because it is synthetic urine. The companys name that is doing these tests is Mid-West Toxicoligy(sp). Just a heads up to everybody!!
