30. Krokodil

Dangerous drugs have been the scourge of humans for many years, destroying the lives of the millions of people who are unlucky to fall into the filthy habit of taking them. What’s sad is that many others are falling prey to newer, more sinister narcotics, one of them is Desomorphine, more commonly known in the streets as Krokodil.

The drug, first introduced in Russia and the Ukraine as a substitute to Heroin, has deadly and horrifying side-effects, thanks to the toxic substances that it contains. These chemicals cause the user’s skin to “rot,” forming large tissue infections that eats through flesh. Searching for Krokodil on Google will lead you to images of its effects, pictures that will definitely make your stomach turn.
