Marijuana doesn't really go through enough hands to be funding crimes like heroin and cocaine do.In most situations it goes from grower to seller to buyer, all you purchase funds is for the dealer to get a new stereo or something. If I buy heroin or cocaine (which I rarely do as often anymore, coke that is not H) it might help contribute to the civil unrest in Columbia and the killing of Narcs (which is good, why should anyone let informants live?).
