While the overwhelming majority of heroin in Europe, Russia, the Middle East, and Asia is supplied by Afghanistan, most of the heroin used in the US is derived from poppy plants grown in Columbia and Mexico.
Additionally, America's national security is now being affected by the opioid crisis. The majority of heroin entering the United States is produced on poppy fields in Mexico, with a slew of significant cartels in charge of production and running distribution centers in significant American cities.
Furthermore, large amounts of heroin are manufactured in South American nations, mainly Colombia, and transported by sea and air to the United States. Afghanistan is the source of the majority of the world's opium, yet the country only produces a minor percentage of the nation's supply.
