I have a friend who for years has used Certo (I think it's used for canning or baking, it's like gelatin) to pass drug tests for MJ. You just gulp it down with water before the test. He smokes up all the time, and (as far as I know) has never come up positive. His work tests him regularly and he still has his job. I've never tried it myself because it seems kind of risky. I prefer just laying off for a few days and then slamming like a half gallon of water before I get my rights violated.
I would think so as well, but somehow this guy has kept his job, despite regular urine testing and frequent marijuana use.
Very true... But it just seemed very out there.... Helping you pass a drug test... Try see if you pass then well know.... Just cause you heard it Doesn't mean its true!
I've heard it can help, but i really dought it, Best bet is to over hydrate and eat low fat foods the day of the test and drink a huge energy drink a few hours before...
