So there's no scientific proof that it works or it don't work then. The science has to work both ways correct? I've also read hundreds of post of ppl who have posted that it has worked for them. There for that's y I think that it could possibly work for sum n not for all. I thought about going with the syntethic urine but kinda get afraid of geting pat down (I had a friend loose her job that way) and I just don't wana risk getin caught n loosing the chance of landing a good paying job. That's y I rather just go with cleaning myself out completely. Plus I'm thinking it can get pretty expensive if u have to drug test again & again & again...lol. But thanx for the info. I'm new here and my no means am I trying to mislead n give wrong info...peace.
