SANTO DOMINGO, Dominican Republic (CNS) — Heroin and painkillers plague the streets of U.S. cities and small towns. Mexican drug cartels have turned swaths of that country into battle zones. In South Africa, young people are getting hooked on a drug made from a medication meant to fight HIV. Around the globe, a worldwide addiction to illicit drugs is fueling violence, human trafficking, a proliferation of guns, organized crime and terrorism, the Vatican has said. Now, as the U.N. General Assembly prepares to meet April 19-21 for a special session on the issue, the church is calling on governments and civil society groups to address a problem that has existed for decades but continues to morph and pose new threats. “From poor rural workers in war-torn zones of production to affluent metropolitan end-users, the illicit trade in drugs is no respecter of national boundaries or of socioeconomic status,” Msgr. Janusz Urbanczyk, Vatican observer to U.N. agencies in Vienna, wrote in the statement. “International solutions require therefore, that effective efforts be indeed focused in zones of production but must also address the underlying causes for the demand in illegal drugs.” The Vatican position puts it at the center of a tense policy that will play out at the highest levels of the United Nations.
