A researcher at the University of Minnesota studying the effects of cocaine apparently tried some of the drug himself. Repeatedly. Dr. Keith Kajander used grant money to buy 140 grams of cocaine over a seven-year period before dying from a cocaine overdose. The university has said it will refund $11,000 in grant money to the National Institutes of Health that Kajander used to buy the drug after admitting it didn’t know how many of the 140 grams went to research and how many went up Kajander’s nose. (AP) ...Which isn’t to say that wasn’t part of his research.
