My friend smoked probably half gram of meth between Wednesday 2pm - Saturday 8am. He was just smoking half points - points at once . He smoked a point at 2pm Wednesdays and was up all night wednesday night drinking lots of water and urinating every 15-20mins . He didn t smoke anymore untill Thursday morning around 11 which would have been another point . He got 6 hours sleep Thursday night . Friday around 2pm he smoked possibly 2points, then at about 9.30 Friday night smoked another half point and then again Saturday at 8am he smoked another half point . Since he has done this over a period of time will it take longer for it to get out of his system ? He s beeb flushing/drinking lots and lots of water to try flush his system out . He started flushing around 10am Saturday morning . ? He s worried parole might ring up for a urine test on Monday . Is there any chance if that was to happen he would be clean if he did the test late Monday afternoon??
