Krokodil drug user pictures show a horrifying effect, and now the Russian drug is here in the United States.  Two krokodil drug users were found in Arizona, reported by the Banner Poison Control center.
The average drug user of krokodil lives only 2 to 3 years once they become a user.  When the drug is injected, it rots the skin by rupturing blood vessels, causing the tissue to die. The skin hardens and rots, sometimes even falling off to expose the bone. Horrifying pictures of krokodil drug users have emerged showing the way in which krokodil rots flesh.
Krokodil is produced using codeine, a legal over the counter opiate painkiller; however, it also uses gasoline, paint thinner, hydrochloric acid, iodine and red phosphorous, which is scraped from the sides of matchboxes by krokodil drug users.

According to official estimates in Russia, up to a million people are drug users of krokodil.  
As for its prevelance in the US, the two cases of krokodil drug users are the first reported cases.  Dr. Frank LoVechhio, co-medical director at Banner Good Samaritan Poison and Drug Information Center in Arizona, told CBS 5: "As far as I know, these are the first cases in the United States that are reported.  So we're extremely frightened."

Time Magazine followed the story of Irina Pavlova, who somehow managed to survive being a krokodil drug user for six years.  Pavlova "developed a speech impediment, and her pale blue eyes have something of a lobotomy patient's vacant gaze. "Her motor skills are shot from the brain damage," says Andrei Yatsenko, the house manager, who was addicted to heroin for seven years. "She'll try to walk forward and instead jolts back into something. So we try to be gentle with her.""
