Opium has been available for 5,000 years. Chinese indigenous opium was inferior to the opium grown by the British on Indian plantations, so opium users favored the imported product. The British essentially forced imported opium on the Chinese, and large numbers of people became addicted. The British used profits to fund its domination of India. The Chinese government tried to control drug abuse in the 19th century, but found it was impossible without British support. The British were very much against the Chinese growing their own opium. There is no reason to believe that poppies are not native to parts of China. See "Opium," by Martin Booth.
