Afghanistan is the world's largest producer of opium. For more than 10 years, US troops have invaded Afghan territory but failed to reduce opium production.
Afghanistan is the world's largest producer of opium, according to the United Nations Office on Drugs and Crime (UNODC). Its opium harvest accounts for more than 80% of the world's supply. In 2018 the UNODC estimated opium production contributed up to 11% of the country's economy.
