ion (minus expenses) was profit made by the East India Company. In addition to securing poppies cultivated on lands under its direct control, the company's board issued licences to the independent princely states of Malwa, where significant quantities of poppies were grown.
By the late 18th century, company and Malwan farmlands (which were traditionally dependent on cotton growing) had been hard hit by the introduction of factory-produced cotton cloth, which used cotton grown in Egypt or the American South. Opium was considered a lucrative replacement, and was soon being auctioned in ever larger amounts in Calcutta. Private merchants who possessed a company charter (to comply with the British royal charter for Asiatic trade) bid on and acquired goods at the Calcutta auction before sailing to Southern China. British ships brought their cargoes to islands off the coast, especially Lintin Island, where Chinese traders with fast and well-armed small boats took the goods inland for distribution, paying for the opium with silver. The Qing administration initially tolerated opium importation because it created an indirect tax on Chinese subjects, as increasing the silver supply available to foreign merchants through the sale of opium encouraged Europeans to spend more money on Chinese goods. This policy provided the funds British merchants needed to then greatly increase tea exports from China to England, delivering further profits to the Qing monopoly on tea exports held by the imperial treasury and its agents in Canton.
However, opium usage continued to grow in China, adversely affecting societal stability. From Canton, the habit spread outwards to the North and West, affecting members from every class of Chinese society. This spread led to the Qing government issuing an edict against the drug in 1780, followed by an outright ban in 1796, and an order from the governor of Canton to stop the trade in 1799. To circumnavigate the increasingly stringent regulations in Canton, foreign merchants bought older ships and converted them into floating warehouses. These ships were anchored off of the Chinese coast at the mouth of the Pearl River in case the Chinese authorities moved against the opium trade, as the ships of the Chinese navy had difficulty operating in open water. Inbound opium ships would unload a portion of their cargo onto these floating warehouses, where the narcotic was eventually purchased by Chinese opium dealers. By implementing this system of smuggling, foreign merchants could avoid inspection by Chinese officials and prevent retaliation against the trade in legal goods, in which many smugglers also participated.
In the early 19th century American merchants joined the trade and began to introduce opium from Turkey into the Chinese market—this supply was of lesser quality but cheaper, and the resulting competition among British and American merchants drove down the price of opium, leading to an increase in the availability of the drug for Chinese consumers. The demand for opium rose rapidly and was so profitable in China that Chinese opium dealers (who, unlike European merchants, could legally travel to and sell goods in the Chinese interior) began to seek out more suppliers of the drug. The resulting shortage in supply drew more European merchants into the increasingly lucrative opium trade to meet the Chinese demand. In the words of one trading house agent, "[Opium] it is like gold. I can sell it anytime." From 1804 to 1820, a period when the Qing treasury needed to finance the suppression of the White Lotus Rebellion and other conflicts, the flow of money gradually reversed, and Chinese merchants were soon exporting silver to pay for opium rather than Europeans paying for Chinese goods with the precious metal. European and American ships were able to arrive in Canton with their holds filled with opium, sell their cargo, use the proceeds to buy Chinese goods, and turn a profit in the form of silver bullion. This silver would then be used to acquire more Chinese goods. While opium remained the most profitable good
