We begin this morning with Dr. Leana Wen. She is Baltimore’s Health Commissioner, and a regular guest on our program for a series we call Healthwatch. Dr. Wen joins us here in the studio once a month to talk about issues affecting the health and well-being of Charm City residents…and she’s just back from the National Prescription Drug Abuse & Heroin Summit in Atlanta, where on Tuesday she joined President Obama and a panel of experts for a discussion of the nation’s, and Baltimore’s, epidemic of opioid drug abuse.
