> Just plain giving them heroin safely, cheaply and predictably can help addicts start to get their lives back on track

That's part of Switzerland's drug policy since the late 90s of the last century. It was confirmed multiple times in referundums by the public and I think it's overall very successful.

The greatest success, in my opinion, is that it completely reversed the image of heroin consumption. By turning it from a "hero" drug to a total loser drug.

Cool kids don't do heroin nowadays.
