Britain began to develop opium trade with China through the East India Company. The East India Company just liked the epitome of the British government in Asia in the 18th century. In 1757, the East India Company took control of the main poppy growing areas in India. The British government receives taxes from these imports and exports. In addition, several boxes of opium were sold at an auction in Kolkata and then smuggled to China. In 1735, there were 200 boxes per year, and then in 1786, each box increased to 1,000. In 1850, 30,000 boxes entered China every year. The opium trade has become one of the most valuable single commodity trade in the world.
