i cannot use a clean persons sample because it is random, they will test me on the spot. From your point of view, how many days would you "think" it would take for the thc to get out of my system considering my size, etc. i am 145 lbs 5' 5". 30 yrs old. An educated guess if you can please? :-) also if I drink plenty of water and cranberry juice and bike riding everyday. Also do you know of any foods that help burn fat? Thank you
