This undated photo provided by Dr. Noah Craft shows a patient that suffered a severe skin reaction after using adulterated cocaine. In a June 7 paper in the Journal of the American Academy of Dermatology, doctors analyzed two cases in Torrance, near Los Angeles, and four in New York where patients showed up at the emergency room complaining of purple blotches on their ears and other areas after taking cocaine. The study's authors say the drug users were suffering adverse reactions to cocaine that had been cut with the livestock de-worming medication levamisole. (AP Photo/Courtesy Dr. Noah Craft) less
