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.
