Lethal Doses

Lethal Doses explores the compelling story behind the rise of fentanyl in America, tracing its origins back to the brilliant yet dangerous chemist George Erik Marquardt, whose early talents led him to produce a spectrum of illicit drugs and dangerous substances. Award-winning author and former undercover agent John Madinger provides an in-depth account of the DEA’s three-year pursuit of Marquardt, shedding light on the origins of the fentanyl crisis that now claims hundreds of lives daily. This revealing narrative is the basis for the hit docuseries, The Godfather of Fentanyl.
