Krokodil drug is the street name for an opioid drug called desomorphine. It is a cheap heroin alternative that’s an opioid derivative of codeine, similar to morphine. Unfortunately, Krokodil also frequently contains other toxic substances like paint thinner and gasoline. So it sometimes goes by other names such as Alligator Drug, Krok, Russian Magic, Poor Man’s Heroin, and Zombie Drug. The drug was first reported in Russia around 2003 after heroin became hard to hold and prices surged. welevelup.com/addiction/krokodil-drug/
