The Indian farmers were reluctant to grow opium, as they wanted to produce opium at a cheap rate and sell it at a high price to opium agents in Calcutta, who then shipped it to China. This difference between the buying and selling price was the government’s opium revenue. The prices given to the peasants were so low that by the early eighteenth century angry peasants began agitating for higher prices and refused to take advances. In regions around Benaras, cultivators began giving up opium cultivation. They produced sugarcane and potatoes instead. Many cultivators sold off their crop to traveling traders (pykars) who offered higher prices.
