A injectable drug new to the US is poisoning people in Arizona.

Desomorphine, which goes by the street name Krokodil, originated in Russia where it was dubbed "the drug that eats junkies." It is three-times cheaper to produce than heroin and gives users an intense high.

The problem is that the drug, which is a mixture of codeine, gasoline, paint thinner, hydrochloric acid, iodine and red phosphorous, is generating gangrenous sores in users that open all the way to the bone.

"We've had two cases this past week that have occurred in Arizona," Dr. Frank LoVecchio, co-medical director at Banner's Poison Control Center, told KLTV.

"As far as I know, these are the first cases in the United States that are reported. So we're extremely frightened," he added.

The drug first reared its ugly head in Russia in 2002; currently there are three million users.
