I have a urine test coming up soon, I ll have been absent for just over 40 days when I take it, would have been closer to 50 days, but smoked about a 1/2 gram after being absent for a week, prior to that I smoked about a gram a day, the cut off for the test is 50 ng/ml, I m 6 3 200lbs, how likely am I to pass this upcoming test?
