Summary: The AIDS crisis is not over was the title of a manifestation in the Museum of Modern Art in Amsterdam in the early 1990s. Given that this outcry is still valid to date, it is also the leading thought of this presentation on the HIV epidemic among young gay men. It will be argued that in industrialised nations,

Grunewald A; Akersberga, Sweden. Fax: 46-8540-60669.
The restrictive Swedish drug policy is considered to be successful in keeping narcotic drug abuse on a relatively low level and has therefore attracted international attention. The Swedish laws are well adjusted to the three UN Conventions on Narcotic Drugs (1961, 1971, 1988). The combination of resources for preventiv
