Me and my friend have been at a debate about whether or not certo works for passing a drug test. He doesn't listen to actual facts on why it wouldn't work, so we are conducting an experiment. (He's willing to put his freedom on the line with certo (probation), and p.s. his PO does NOT take diluted piss) We are going to conduct an experiment. We both are everyday tokers. I am going to go buy 2 at home THC tests. For the first one, he i going to only use 1 packet of certo, with NO water diliution because he believes its the certo and not the water allowing him to pass. I will be using certo, and DILUTING with it...as I read about everyone doing when using certo, which is why it works...go figure) I'm going to post the results on here, because I GUARENTEE that certo does NOTHING for passing a drug test...its the dilution that allows you to pass a drug test. Anyone got any comments about using Certo to pass? I'm 100% against that it indeed does NOT work.
