I have used my wife's piss to pass 2 drug tests. I had her piss across the street from the place in a container.(we have a dunkin dounuts across from the drug test place) I used a hand warmer (Hot hands) Put the piss and hot hand thing into my boot and put my pant leg over boot. Went into place filled out the paper gave my id and off to the bathroom. Once inside I got the piss out poured into the cup (my piss test cup had a temp guage on it so I made sure it went up enough) If it dont just touch the hot hands pad to the temp guage for a sec. Not too much you dont want it to get to hot. Then I put the empty container and hot hand pad back into my boot and flushed the toilet. I passed 2 this way at 2 different drug test places. I never had aproblem. I worried ALOT about my tests and it worked out great. If I ever have to take one again I will do the same thing! Good Luck
