You've never been to Switzerland if you think there are no drug dealers there.

I don't know about heroin, but there are something like 3/4 Swiss cities in the top 20 for cocaine consumption based waste water sampling.

There are, in fact, even heroin dealers in Switzerland, and of course all sorts of other drugs are still being sold illegally, but compared to the early 1990s, before the heroin prescription policy, there is practically no visible drug addict scene anymore.
