China is now a major international supplier of precursor chemicals for the manufacture of the frightening and ruinous drug Ice and other new-generation drugs. "The quickest way to make a fortune is to deal drugs - to sell drugs here", Professor Wu Jiang tell us. This report takes us right into the heart of the illicit tearaway trade on the Myanmar border, where drugs flow through in huge quantities. But for the Chinese it's not just the through traffic of drugs that's worrying. "The number of drug dealers doesn't seem to change much, but there are many more drug users", a Chinese man on the border explains. In the super-cities like Shanghai, unlike previous generations China's partying young are driving a booming market in so-called recreational drugs. It has become, "fun and fashionable to take drugs". One credible report estimates the number of registered drug addicts has grown from 70,000 in 1990 to nearly 2 million a year ago. The number of regular drug users may be as high as 12 million. If it continues to grow exponentially, it's a social, health and legal time bomb for the Chinese authorities.
