The main purpose of this evaluation was to determine to what extent the principal goal of Dutch drug policy has been achieved, as stated in the 1995 Policy Document on Drugs (Drugsnota). This asserts the primacy of protecting public health, and thus gives priority to drugs prevention and to the management of the individual and social risks that arise from drug use.
Building on a long history and culture of tolerance, the Dutch responded to illicit drugs with decades of pragmatic measures free of judgment. A central element of modern Dutch drug policy was a crucial decision to establish a legal and practical separation of cannabis—judged to pose "acceptable" risks to consumers and society—from hard drugs associated with unacceptable risk. This policy effectively decriminalized possession and use of cannabis and opened the door for tolerated outlets for small-scale cannabis sales that eventually took the form of the well-known Dutch "coffee shops."
The head of the UN Office on Drugs and Crime (UNODC), Antonio Costa, recently visited Amsterdam on 24 April. Accompanied by some officials of the Netherlands Ministry of Health and of the City of Amsterdam and UNODC staff, he dropped in on the coffeeshop De Dampkring (the Atmosphere) and a user room (for inhalation and injection of heroin and cocaine). He wrote his personal account for his blog Costa’s corner but it was never published. Apparently it proved to be too controversial with his Dutch host. It now has popped up on the Transform drug policy blog and the ENCOD website.
