The Platzspitz or “Needle Park” in Zürich was one of the world’s most notorious open drug scenes, attracting users from all over Europe. After its closure, a new drugs policy was introduced in Switzerland to better protect drug addicts. Dr André Seidenberg was a pioneer of this approach. Swiss TV took him back to the Needle Park, along with a heroin addict who was heavily involved in the scene at that time.
