Since mere possession and use is such a minor offense, in most places, as to be no offense at all; we have in effect legitimatized the market for drugs. So our drug policy states the market is legitimate but serving that market is not. Which is a little screwy. It can't work. And that leads to foreign cops and soldiers dying in large numbers trying to stop their countrymen from selling us something we really really want. Which is not only screwy but dishonorable.

A small point but one of the reasons for drug prohibition is to make sure the potential economic contribution of users isn't lost. From observation I believe most of those people will never contribute in any event so we are trying to preserve something that isn't there in the first place.
