How did heroin spread beyond big cities in America? What's the connection between heroin and America's opioid problem? Sam Quinones, author of Dreamland, talks with EconTalk host Russ Roberts about the explosion in heroin use and how one small Mexican town changed how heroin was produced and sold in America. That in turn became entangled with the growth in the use of pain-killers as recreational drugs. Drawing on the investigative reporting that culminated in his book, Quinones lays out the recent history and economics of the growth in heroin and pain-killer usage and the lost lives along the way.
