Even with a Joliet, Ill., drug treatment physician, publicly stating that he's seen as many as four users of Krokodil, the DEA is not sounding the alarm.
The drug, which is made by cooking codeine with various chemicals, such as lighter fluid, gasoline and industrial cleaners, was first reported in 2011.
It's been on the radar, with Krokodil reports in the U.S. making news lately.
Still, federal officials say they are skeptical that the nightmare drug, a cheap heroin knockoff, that originated in Russia has reached American soil.
“We, the DEA, are not seeing cases of it,” agency spokeswoman Dawn Dearden told Fox News Thursday. “Nothing’s been turned into any of our labs."
"As far as the DEA is concerned, we have not seen any cases.”
