More and more Americans are dying from drug overdoses, underlining warnings given in recent years by federal health officials.

FOX's Eben Brown reports:

Drug overdoses resulting in death have increased nearly 25 percent in the past few years, with nearly 50,000 OD deaths nationwide. The findings are part of a study by the National Center for Health Statistics done from 2010 to 2014.

Oxycodone has been replaced as the drug most overdosed by street-grade heroin, accounting for a quarter of overdose deaths in 2014. But the number of deaths attributed to Fentanyl have quadrupled in the same time period. Fentanyl is similar to morphine but infinitely more potent, and is now being made in makeshift illegal labs.
