World drug report 2012

Many illicit drug markets have reached global dimensions and require control strategies on a comparable scale. In that context, there is a need to better understand these transnational markets and the manner in which they operate. This annual report is a contribution towards that objective. It presents comprehensive information on the illicit drug situation and provides detailed estimates and trend analysis on production, trafficking and consumption in the opium/heroin, coca/cocaine, cannabis and amphetamine-type stimulants markets
