This hour: the deadly reality of counterfeit drugs. We discuss the history and proliferation of fake pharmaceuticals with Dr. Muhammad Zaman, author of Bitter Pills: The Global War on Counterfeit Drugs, and consider their impact both internationally and at home. 

Also: a new report from the Centers for Disease Control and Prevention outlines an alarming trend in the U.S. -- fleas, ticks, and mosquitos are on the rise. But what, exactly, is driving the increase? And what does it mean for public health?
