Billions of dollars are funneled into federal drug programs to keep our children away from drugs and our cities safe from crime and economic turmoil. Our guest this week, journalist and author Johann Hari, has spent the last several years traveling and researching the war on drugs for his new book Chasing The Scream: The First and Last Days of the War on Drugs, to find out if federal programs are as effective and righteous as we are often led to believe.

Hari talks to host Josh Zepps about how he discovered the troubling beginnings of drug war riddled with corruption and ulterior motives, and argues that everything we thought we understood about drug addiction appears to be wrong.
