Flesh-Eating Krokodil (S06E01)

When heroin users in America began turning up with raw lesions, decaying skin and grotesque sores, doctors were worried. The symptoms looked like those associated with Krokodil ' a home-cooked, super-strong opiate that got its start in Siberian Russia. Made from codeine cooked with toxic ingredients, Krokodil can be stronger than heroin, and more addictive. Drugs, Inc. journeys to Armenia, Georgia and Ukraine to meet Krokodil's users and dealers as they reveal the true horror of this drug. (National Geographic)
