China had the highest national use of opium in the mid-1800s, with an estimated 10 million people addicted to the drug. This was due to the opium trade from British India, which was fueled by British demand for tea and Chinese demand for silver. The opium trade had devastating effects on Chinese society, leading to widespread addiction and social and economic decline.
