Why were measures taken to stop the opium trade between china and great Britain?

Measures were taken to stop the opium trade between China and Great Britain primarily due to the severe social and health impacts of opium addiction in China. The Chinese government sought to curb the crisis by enforcing bans on opium imports, leading to heightened tensions with Britain, which was profiting immensely from the trade. The situation escalated into the Opium Wars, ultimately resulting in China's defeat and the signing of treaties that favored British interests, but also highlighted the need for reform in China's approach to foreign trade and opium control.
