A mysterious flesh-eating drug, Krokodil, is now spotted in the US, particularly Arizona. The drug first emerged in Russia about ten years ago, Fox News reports.

Krokodil is made up of mixed codeine with gasoline, alcohol, paint thinner or maybe even oil. The weird mix is injected into the veins which causes the skin to turn green, scaly and eventually rot.

According to Dr Frank LoVecchio, the co-medical director for Banner Good Samaritan Poison and Drug Information Center based in Arizona, there have already been two cases of the use of such a drug mix within the state. However, he did not make any additional comments about it yet.

It was in Russia that a large number of uses of Krokodil were discovered. It was the Federal Drug Control Service of Russia who told Time that there were 65 million doses of Krokodil that were taken during the first quarter of 2011.

Dr Aaron Skolnik, a toxicologist from the same hospital in Arizona expressed how frightening the situation can be if it gets worse. "This something we hoped would never make it to the U.S. because it's so detrimental to the people who use it," he stated.

Codeine is a controlled substance within the US and only used for treatment of mild pain. However it is an over the counter drug in Russia, according to Fox News.

In 2010 the estimated number of people using it reached to a million in Russia alone, as Time mentioned. Other reports say that the Krokodil first appeared within Siberia in 2002 and just spread in the country eventually through the more recent years.

On the other hand, Dr. Lewis Nelson who is a toxicologist from Bellevue Hospital Center based in New York said two years ago that Krokodil won't likely to become a "club drug" in the US since there are other cheaper yet more potent drugs in the country like Oxycontin and black tar heroin.

Just like other IV drug addicts, the Krokodil users are prone to get inflicted with diseases like HIV and hepatitis C along with other ailments that are blood borne.

One Russian lady who was a Krokodil user way back in 2011 mentioned to The Independent that she knew a fellow addict who refused to get help from the hospital. Her friend's flesh was "falling off" and the patient could barely move, USA Today mentioned.
