Desomorphine or Krokodil is a home-cooked opiate-based drug that is reportedly up to ten-times stronger than heroin and many times cheaper. With a high toxicity, the effects of the drug are both terrifying and fatal. The name Krokodil comes from the reaction users experience – skin will become greenish and scaly, resembling that of a crocodile.
Krokodil has become increasingly popular in Europe among heroin addicts, though horrific effects the drug has on the body mean that users don’t have their addiction very long. Users will often die within two years of using this home-made drug, made with a combination of pain medication and toxic chemicals. Some of the ingredients include, but are not limited to, a combination of codeine-based tablets, paint thinner, lighter fluid, gasoline, hydrochloric acid, red phosphorous (scraped from matchboxes) and iodine.
Users often continuously cook up the drug in their kitchen to ensure they can maintain their high. The caramel-colored liquid is injected into damaged and gangrenous areas giving users a high that will last 30 minutes at most. The toxic nature of the chemicals in krokodil cause users' skin to change color, turn scaly and eventually become gangrenous. Users' skin will be covered in ulcerations around the injection sites as blood vessels rupture and cause tissue to die. The users skin will eventually be eaten away by the chemicals in the drug which rots flesh to the bone. Users teeth with literally rot out of their heads, brain damage is common and tetanus and blood poisoning is nearly assured.
