In what could seem like a plot out of The Walking Dead, a flesh-eating drug with Russian origins has emerged in the United States.

NBC Chicago reports that Presence St. Joseph Medical Center, located in the Chicago, Ill. suburb of Joliet, has treated patients who claimed to have used the drug called "krokodil." Dr. Abhin Singla says the drug has similar characteristics to methamphetamine but not as expensive. As with meth, users can concoct krokodil using codeine and household products like paint thinner or gasoline.

“It is a horrific way to get sick," Singla said. "The smell of rotten flesh permeates the room. Intensive treatment and skin grafts are required, but they often are not enough to save limbs or lives.”

Long-term use of krokodil causes gangrene and abscesses on the human body, and in some more severe cases, muscles and bones become visible. The drug can be injected into the body or consumed orally, making it a cheaper option compared to heroin.

We hope we're not one krokodil use away from the zombie apocalypse.
