Needle Exchange

So I like to do a fairly (perhaps even radically) liberal playthrough and thus one of the things I enjoy doing is trying to get Narcotics fully legalized without triggering a Drug Addiction crisis.

And it IS possible if you take every step possible to reduce drug addiction in the country. This includes the rather conservative policy of maximizing Armed Police (I believe the logic behind this is not that the cops with guns will stop people from becoming addicted but rather keep the addicts u der control).

This would be fine, I understand compromises must be made sometimes but… I can’t figure out why the Needle Exchange Program policy does nothing at all to curb Drug Addiction when the flavor text explicitely states that the program helps people get clean.

Surely this is an oversight?
