I'm wondering if someone can answer why my system isn't clean. I got a P.O. and being tested for weed. I've stop completely and have been for two month but as I do each week, I went to see Ms. Walker and requested her to give me a drug text but I failed. Now she acts like I'm not being honest. I quit cold-turkey and haven't look back. When I did smoke I was one of the biggest smoker around. I'd smoke 15 to 30 grams a day but now It's seems that I can't get clean. How long, does it take for weed to get your system? don't forget tak I'm almost 6'4 at 245 pounds.
