I know many people that have failed with the drinks! I would never trust it. All my friends use the wisanator(spell)
The Original Whizzinator - HOME - Pass Your Drug Test!. It is not cheap but it does work. I Like I said I have never had to use it but I was in line with my friend that had a test right before meand we where at a party the night before and he smoked all night. I knew for 100% he was dirty(I was clean) . Any how he passed. You know what was funny tho was he got in a accident at work(whenever that happens we have to piss again no matter what) and needless to say he dint have his back up and he failed.
