In 1729, the Chinese banned the smoking of what product?

In 1729, the Yongzheng Emperor of China issued the world's first anti-drug law, targeting the sale and consumption of this powerful narcotic. The edict was a direct response to a growing social crisis. While the substance had been known in China for centuries as a medicine, the practice of smoking it recreationally was a more recent development introduced by foreign traders. This method of consumption was found to be far more addictive and destructive, leading to widespread addiction that the emperor saw as a threat to social order and productivity.

The ban specifically targeted the burgeoning "opium dens" where people gathered to smoke the drug. The court was concerned that the practice was causing citizens to neglect their work, drain their family finances, and fall into a state of moral decay. The imperial government hoped that by criminalizing the recreational smoking of the drug, it could stamp out the problem before it spread further from the coastal provinces into the heart of the empire.

Unfortunately, this early prohibition was largely unsuccessful. The immense demand for the drug, coupled with the enormous profits to be made, meant that a vast smuggling network (Review) quickly emerged. Foreign merchants, particularly the British East India Company, ramped up illegal importation to feed the growing addiction. This escalating conflict over the illicit trade would eventually culminate in the devastating Opium Wars of the mid-19th century, more than a hundred years after this initial ban.
