Get a friend to pee in a small bag. Pour it into a thermos right until you get to the place where you get tested. Then roll up the small bag and hide it somewhere that will keep it warm (like between your legs). Pour it into the sample cup they give you and you are home safe. Unless all your friends are druggies.

one was born with a knowledge of God. -Voltaire
