Numerous UN conferences and summits have been devoted to negotiating a harmonized global approach to illicit drugs. Yet more and more cracks are beginning to appear in the supposedly universal model which is based on a highly fragile consensus. The failure to counter the ever-growing problems related to the use of illicit drugs has led countries to question current policies and to experiment with approaches less driven by the US-inspired ideology of "zero tolerance" and more rooted in pragmatism. This has led to increasing acceptance of the concept of harm reduction for consumers, where drug use is treated as a public health rather than a law enforcement problem. On the production side, discussion centers on the need to secure alternative livelihoods for involved farmer communities and how to most effectively promote alternative development.
Drug consumption rooms have been established in several countries, where confirmed drug users are allowed to consume their drugs in hygienic conditions and without fear of arrest. These facilities, which mostly operate in big cities, emerged because of serious health and public order problems associated with drug use, especially drug injecting in public places. In 2004, there were about 60 consumption rooms in 36 European cities and two pilot projects of medically supervised injecting centres in Australia and Canada.
