For those who dabble in the white world, it may be time to think twice about what is really in your $50 baggie. Officials in Alberta have discovered that Canadian coke heads have been exposed to tainted blow, and seven people have been diagnosed with "agranulocytosis, a condition that makes the immune system incapable of fighting off infections." This is something a flu shot will not prevent people. Apparently, "officials have linked the cases to cocaine laced with levamisole, a chemical compound developed to treat intestinal worms in humans and animals." And now people are snorting it for fun. What a wonderful world. [CBC]
