How's this for a crazy statistic: according to the Center for Disease Control and Prevention, more people die each year from drug overdoses than car accidents -- and 70 percent of those deaths are caused by legally prescribed medication. Kaleo, a pharmaceutical firm, hopes it can change that. It's creating a device called Evzio, a small, easy to use drug delivery system that can safely administer a life-saving dose of naloxone. This device could save the lives of thousands of patients who have been prescribed legal opiates to treat pain. Not sure how to use it? Don't worry about it: it talks.
