One-Third of All Cocaine Seized in U.S. Laced With Lethal De-Worming Drug

(AP) Nearly a third of all cocaine seized in the United States is laced with a dangerous veterinary medicine - a livestock de-worming drug that might enhance cocaine's effects but has been blamed in at least three deaths and scores of serious illnesses.

The medication called levamisole has killed at least three people in the U.S. and Canada and sickened more than 100 others. It can be used in humans to treat colorectal cancer, but it severely weakens the body's immune system, leaving patients vulnerable to fatal infections.

Scientific studies suggest levamisole might give cocaine a more intense high, possibly by increasing levels of dopamine, the brain's "feel-good" neurotransmitters.

Drug Enforcement Administration documents reviewed by The Associated Press indicate that 30 percent of all U.S. cocaine seizures are tainted with the drug. And health officials told the AP that most physicians know virtually nothing about its risks.

"I would think it would be fair to say the vast majority of doctors in the United States have no idea this is going on," said Eric Lavonas, assistant director of the Rocky Mountain Poison and Drug Center in Denver, where as much as half of the cocaine is believed to contain levamisole. "You can't diagnose a disease you've never heard of."

Authorities believe cocaine manufacturers are adding the levamisole in Colombia, before the cocaine is smuggled into the U.S. and Canada to be sold as white powder or crack.
