Well i gotta say you can pass if you say you excersise often and just drink lots of water and cranberry juice. Especially if you are a thin person you burn out the THC in your fattie cells much faster.. just make sure that you excersised enough and sweat alot. I've been smoking for 3 years and i literly smoke everyday about 2 or 3 blunts.. it takes me 1 to 1 1/2 weeks to get clean if i excersise constantly and drink lots of water and cranberry juice for those days and DON'T SMOKE!:rastasmoke:
