wish i got a notice for my random drug testes, they just drive out in the field, snag me up and were on our way. You need to get some synthetic urine, someone mentioned quick fix that is what i use and have used it well over 20times, gonna buy stock in the company soon. It comes with a heat pad, i get the bottle typeand put it in slide it down on the side of my knee high socks while wearing pants of course, temp sensor side to skin and heat pad on out side, takes 15mins to hit the desired temps, check out your local smoke shops
