Desomorphine, drug for the poor, kills all of its victims
23.06.2011
The police of the city of Ufa found a drug nest in one of the city apartments. The police found a pregnant woman and two young mothers in a state of strong narcotic intoxication in a common city apartment in Aurora Street. Investigators have determined that the flat was used for the production of one of most dangerous drugs - desomorphine, which is known in Russia as 'crocodile'. Unlike heroine, the drug is available to practically anyone. The ingredients for the production of desomorphine can be bought in a common drug store without any prescriptions. A person, who becomes addicted to crocodile, usually begins to rot alive.

Just as crack is the broke addict’s cocaine, krokodil is a substitute for a much more expensive drug, heroin. The chemical behind krokodil, desomorphine, was available as a morphine substitute shortly after laboratory synthesis in 1932. Desomorphine is 8-10 times more potent than morphine. The medicinal use of desomorphine was concentrated to Europe, particularly Switzerland. The synthetic opiate has a structure nearly identical to heroin.

The above chart shows how it's made.
In Russia.... Drugs eat you!!!
