I guess it depends on who you are. Don't believe that month gimmick either. I know a couple of guys that couldn't pass after 50 days. For me I'm not sure. I might smoke for a straight week and can pass in three weeks. I'll have a test coming up where I have smoke for a solid month. I'm on day 17 clean now still pissing hot, hoping to buy myself another week or two. It depends on who you are and how much you smoked. Sucks the good lord made a drug so great and so harmless that can be detected for so long. Makes me wanna switch to snorting coke or something.
