Quizplus · Accepted Answer

The British used opium to break China's self-imposed isolation. They smuggled large amounts of opium from India into China, which created a huge demand and addiction among the population, leading to social and economic problems for the Chinese government. As a result, the Chinese government attempted to crack down on the opium trade, which ultimately led to the Opium War between Britain and China.
