This was followed up by another study done by the World Bank and the UN Office on Drugs and Crime, entitled Afghanistan's Drug Industry: Structure, Functioning, Dynamics, and Implications for Counter-Narcotics Policy. It estimated that the trade at that point had increased to about $3 billion, accounting for 92% of global production and for about one-third of the total economic activity of Afghanistan.
Une autre étude de la Banque mondiale et de l'Office intitulée Afghanistan's Drug Industry: Structure, Functioning, Dynamics, and Implications for Counter-Narcotics Policy a estimé qu'à ce moment-là le trafic était passé à environ 3 milliards de dollars, soit 92 p. 100 de la production mondiale et environ le tiers de toute l'activité économique de l'Afghanistan.
