Okay, so i recently got into trouble and have to take a drug test but i don't know when. i've been clean for about a week and three days and i think i'm what is considered a light smoker? i am about 5'7 and 114 pounds and have a really fast metabolism. i have been drinking like 9 big cups of water a day but am still freaked out cause if i don't pass i'll have to go into some kind of program. Any tips?
