Unfortunate for the Europeans, the Chinese did not have a lot of demand for European products, and so you had a balance of trade problem. These products would be exported from China into Europe, and you would have hard silver currency going to China. And so the imperial powers, especially the British, were looking for a solution. And they eventually found that opium grown in India, which is a highly addictive drug, it's the core constituent of heroin and morphine, could be addictive to the Chinese people, and maybe could help solve this balance of trade problem, that silver could then flow outside of China. Well you could imagine the Chinese government, the Qing Dynasty, had no interest in opium coming into China. It was destructive to their society. It was an addictive drug.
