I haven't smoked in 9 days and get tested in 4 days. I am 5'2 and weigh around 112 pounds. I go to the gym a lot and sauna as well. I eat relatively healthy and have a high metabolism. I just tested myself and I failed. Last time I used two detoxs and drank two gallons of water in a day and just threw it all u and they didn't even work for me. i feel like the world is against me and I really can't fail this next drug test. Someone help what should I do do cranberry pills really work?
