Description:Counterfeit, adulterated, or otherwise compromised prescription drugs are a major problem in Africa and a growing problem in the First World, argues Bate. In recent years, counterfeiters passed off hundreds of thousands of phony Lexapro pills around the globe and in 2008 at least 149 Americans died from fake Heparin, a blood-thinning drug. All told, says Bate, the number of deaths globally from ineffective drugs ranges from 100,000 to 1 million.(7:02)
