Alright, so I don't have a scheduled drug test yet, but I have a feeling I will in about two weeks. What is the best way to go about detoxing my body? I'm about 5'10" 185 and I smoked probably 4 times last week. I've heard about GNC drinks and about Metamucil, but i'd be happy to spend the money on a drink or something if I knew it would work. Any tried and true methods? Thanks!
