In February 1991, a deadly new drug hit the streets of New York City, packaged in small baggies marked 'Tango & Cash,' leading to a surge of overdose deaths. This crisis quickly spread to other cities including Philadelphia and Boston, prompting law enforcement to issue warnings through loudspeakers in affected neighborhoods. The source of this new scourge was traced to George Erik Marquardt, a high school dropout who had established a makeshift fentanyl lab in Kansas. A new four-part documentary, 'The Godfather of Fentanyl,' features rare interviews with Marquardt, likening him to a real-life Walter White from 'Breaking Bad.' Marquardt's early fascination with science and his criminal activities began well before his infamous fentanyl production, as he had previously been involved in making LSD and meth. The documentary reveals Marquardt's perspective on his life choices and the devastation his actions caused across the nation.
