Colombia’s government and the FARC guerilla organization announced an agreement May 16, entitled "Solution to the Problem of Illicit Drugs," in which they pledge to work together agianst the narco trade. The FARC, whose top leaders face extradition to the United States on trafficking charges, agreed to "end any relationship" with the illicit drug trade, and cooperate in a "National Program for the substitution of the illicit uses of coca, poppy, and marijuana crops." The accord calls for "integral development plans" for rural communities impacted by the drug trade, to be drawn up with the participation of those communities, in the context of an "Integral Rural Reform." It also calls for an international conference to be held under the auspices of the UN to reconsider global strategies against drugs—the one veiled reference in the agreement to the FARC's earlier proposals to decriminalize cultivation of coca leaf and cannabis. "With this we will eliminate the gasoline that has fuelled the conflict in Colombia—drug trafficking," said the government's lead negotiator, Humberto de la Calle.
