I have been searching all of these forums to see how others have passed their drug tests. Most forums stated that the Strip NC stuff works for them every time. I told a friend about this method and he stopped smoking weed nearly a month before his drug test and loaded himself up on gallons of water ever day of that time. He also purchased the Strip NC week long pills and took a proper drug test at a clinic to see if he had passed. It was about 3 weeks later and he failed miserably! He still had 220 ml in his system at that time. He then took the Strip NC pills and 1 Oz. bottle hours before his real drug test again with lots of water and he failed again. He is a very fit person who works out daily and has little if any body fat. Everything we were told on these forums is crap because he followed all of them and he still failed terribly. Some of these people are saying they smoked up to days before their tests and still passed. I don't believe it anymore. It seems to me that these people who are on these forums are stating that these so called cover ups work, probably only work for the companies and are full of it. Just thought I would post and let all of you know that the only way to really pass a drug test is to either quit smoking a long time in advance, or substitute someone else's piss if that is possible. In my friend's case substitution wasn't an option, since he had a full physical moments before his piss test and he was stripped down to nothing (even had the doctor feeling his balls for hernias). Any comments would be appreciated.
