disrupting Afghanistan's lucrative opium market." Both demand and supply reduction are important. "the consuming countries need to get serious about curbing drug addiction. If there was less demand for heroin, the bottom really would fall out of the opium market." Farmers economically dependent on opium must have viable alternatives that give sustainable income. On the supply side, identifying the most-wanted traffickers and subjecting them to international arrest warrants with extradition, asset seizure, and travel bans could help. While it is not easy to destroy opium storage and heroin production laboratories, it is far easier to destroy drugs at the source than in transit. "Afghanistan's neighbors are either accomplices or victims in the opium trade, so they need to be part of the solution. They could, for example, improve intelligence-sharing and border security to ensure that more opium is seized. At the moment, less than a quarter of the world's opium is intercepted, compared with around half of global cocaine output." This complicates, of course, the complex US relations with Pakistan and Iran. The nexus between the drug industry and hawala There is an important nexus between drugs and hawala (informal money transfer system) in Afghanistan. The UN analysis is based on interviews with a sample of 54 hawala brokers in the main centers of hawala activity of Afghanistan as well as during a visit to Peshawar, Pakistan. In addition, interviews were conducted with users of the hawala system (drug dealers, businessmen, traders, international aid workers), regulators (government officials, central bank personnel), and formal service providers (bankers, accountants). In addition to hawala, they found protection payments and connections, by which the drug industry has major linkages with local administration as well as high levels of the national government. See informal money transfer systems to support clandestine activity, including terrorism, drug trade, and intelligence collection. See the section of the article, CIA transnational anti-terrorism activities on how the intelligence community and the United States Department of the Treasury attempt to control hawala used to finance terrorism. Different localities studied by the UNODC give different views of the laundering of drug funds. It is difficult to get a solid sense of the overall economy. In Faizabad, for example, indicated that during certain times of the year close to 100% of the liquidity of the hawala system in the province is derived from drugs, whereas in Herat, the Northern Alliance stronghold, it was estimated
