Okay, now I am not sure exactly HOW it works, but I do know that it DOES WORK!!! In order to pass a piss test you don't need to think of all of these crazy ass ideas to get someone else's piss in the room with you. All you need is....YOURSELF. HOW TO: This was almost so simple it blew me away. All you have to do is 1st: Piss about 1/3 of your piss into the toilet first, then hold it. 2nd: Now piss the middle of your urine in the testing container, then hold. 3rd: Now piss the rest into the toilet. My cousin has used this method 11 times and swears to it. I was with him when he was smoking a fat blunt and then had a piss test 2 hours later!! He said that there is something about the middle part of your piss that doesn't contain any evidence of drugs. Something about concentration. If anyone would like to elaborate on this, please go right head. But that is how he told me to do it. I hope this helps anyone out out there who has a piss test coming up.
