Maybe if that someone was just smoking pot and otherwise paid taxes. This particular group of drug users are not the central point of concern of the UN Special Assembly, even though its part of the wider problem. They are not dying in the streets and they are not socially marginalized. Allthough (anecdotally) i've known several fumb pot-smoking ducks who thought they could finance their proclivity through distribution and wound up several thousand dollars in debt to people who take names and chew bubble-gum.
