Drug abuse in China can be traced to the late Qing Dynasty (1644-1911 A. D.), when British colonists forcefully brought Indian opium into China for exchange of silk, tea, and cash. Opium was then locally planned. By the founding of new China in 1949, more than 20 million Chinese people were opium addicts, representing 5% of the total population [3] . After a short nationwide antidrug campaign, drug abuse was reported to be eliminated from the mainland in the early 1950s, and for the next three decades China was believed to be a drug-free nation [3] .
