Deaths from drug overdoses in the U.S. skyrocketed 21 percent last year according to the CDC.
For the first time, the powerful painkiller fentanyl and its close opioid cousins played a bigger role in the deaths than any other legal or illegal drug.
The drug deaths drag down life expectancy in the U.S. for the second straight year.

Early detection can mean fewer cancer deaths and better outcomes for patients.
Some 11 million low-income Americans have been able to join Medicaid since the passage of the Affordable Care Act in 2010.
