The United Nations Office on Drugs and Crime reports that China (including Hong Kong, Macau and Taiwan) consume 70 percent of all the heroin that is abused in the East Asia and Pacific Region.
Up to 65 tonnes of heroin is used by addicts in China each year. In order to meet the demand, 90 percent of all heroin that is produced in the Golden Triangle (Laos, Myanmar and Thailand) is trafficked to China. Laos has also begun increasing its opium production, with an increase of 66 percent of opium farming taking place in the country in 2011.
Criminal justice and public health programs in China have officially registered 1.2 million heroin addicts in the country.
