I assume you are talking about "street" drugs, not EVERYTHING. The Netherlands tried this tactic years ago, to legalize marijuana and give out free needles to the addicts for safety sake. Total flop. People came from all over the world to sleep in the streets and parks, taking advantage of the system and in general creating a locale for useless (to society) addicts. Recently the law was repealed. I believe they restrict the needles to citizens only. These people need more than free access to their crutches, they need free access to mental health.
