Cocaine cut with a drug used to deworm cattle is causing people's ears and noses to literally fall off, and their doctors may not even know why, says a group of Canadian physicians.
"I equate it to voluntarily walking into a zone of radiation," said Dr. Alan Kaplan, a family physician in Toronto. "You're basically taking a chemical here that's going to do similar things to you."
It's long been common practice for street dealers to cut cocaine with levamisole, a veterinary immune system drug that's been banned from human use in Canada since 1999. Now, it's mostly used to deworm cattle.
