Just sell the drugs from the government. Make it super lame, and medicalized. Cut off the funding for the glorification of drug use in art and music, and make it like the junkie DMV. Sell perfectly pure, precisely diluted, heroin/coke/whatever and then make the addicts stay in the room until they're presentable. Don't let them take needles etc out. Anything else is a half measure that keeps all of the problems with the black markets and all of the social impact of addiction.
