I haven't smoked since May 14th 2013, and my pre-employment drug test was yesterday, August 12th 2013. Roughly 90-91 days sober from marijuana, I have drank water for every meal, including whenever I got thirsty during this time. I've also increased my fiber intake, and have pooped a lot. I'm 26, 5'10, 190 lbs, and I smoked heavily every day for years. I did a take home drug test and was negative, but those things can sometimes be misleading...
