How Switzerland defeated its heroin epidemic

In the 1990s, Switzerland decided to tackle one of Europe's worst drugs epidemics by trying radical new policy ideas including providing safe-injection rooms for addicts and even prescribing pure heroin. The new strategy dramatically cut overdoses, HIV infections and the number of new users, and in 2008 the Swiss voted in a referendum to enshrine the changes permanently in law. Zak Brophy talks to Andre Seidenberg, a Swiss doctor who worked with addicts for decades, and to former Swiss president Ruth Dreifuss, who campaigned for the change in policy.
