Krokodil, already a popular drug in Russia, has finally made its way to the United States. The Banner Poison Control Center in Arizona has reported two cases of the flesh-rotting drug’s use, believed to be the first in the US. The drug is a mixture of codeine and hydrocarbons like gasoline, paint thinner, or oil that is injected directly into veins. It’s named krokodil because once injected, it rots your skin from the inside out, causing an alligator skin-like appearance. It’s really, really gross. You probably want to avoid the YouTube videos.
You should really stop doing cocaine. Not because it's addictive, or anything, but because it's likely laced with levamisole, a veterinary drug used for de-worming livestock, and it will make your flesh rot off.
