The Netherlands have a minor problem with heroin compared with most Western European countries. One of the main reasons is the setting up of "coffee shops" over 20 years ago, along with a sensible education policy. The coffee shops decriminalised cannabis and separated the market for cannabis from that for hard drugs. Another mainstay of their policy is to treat addiction as a medical and social problem and not as a criminal problem, which has led to the trials with prescribing heroin. As well as a relatively small, stable number of heroin addicts they also have the lowest rate of teenage use of cannabis in the western world. Why are this country's political parties so blinkered?
