19th centuryBankers from London to New York have made a killing off the drug trade for hundreds of years. Demand only grows the more markets are flooded with drugs — but the interconnections between the drug trade and imperialism go deeper than profit. Historian Alfred W. McCoy’s 1991 book “The Politics of Heroin: CIA Complicity in the Global Drug Trade” traces the threads of the drug trade throughout the Cold War, demonstrating the role of the U.S. intelligence community and big banks in undergirding the global drug trade.

This marked the advent of the most brutal and violent epoche in the history of the drug trade in Mexico.
