MICHEL MARTIN, HOST:
Drug overdose deaths in the U.S. continue to surge. The Centers for Disease Control and Prevention released new data this week showing drug overdoses killed more than 107,000 people in the U.S. last year. That's another record. Correspondent Brian Mann reports on addiction for NPR, and he's here with us now to tell us more. Brian, welcome. Thank you for joining us.
BRIAN MANN, BYLINE: Thanks, Michel.
