And yet it was widely available on the streets back when it was illegal, and now it's hard to find on the streets and it's still illegal. So what changed? Clearly it was not the law that fixed things, right?

> Also there still is a heroine problem though arguably smaller than it used to be.

A tiny fraction of what it used to be. Since I would consider that success, I don't get your point? I very much doubt anyone is expecting addiction to disappear? The point is that it costs tax payers far less when you fix the actual problem instead of trying to treat medical problems as if they are a legal problem.

Very few people are incarcerated for dealing because people with this problem have better and safer alternatives than street scores.
