Fentanyl is a powerful opioid that is 50 to 100 times more potent than morphine and 30 to 50 times more potent than heroin, and a dose as small as a quarter of a milligram can be fatal.
Drug enforcement officials say they confiscated enough fentanyl, a deadly synthetic opioid, to kill 26 million people.
As NPR's Brian Naylor reported, much of that fentanyl is coming from overseas through the U.S. Postal Service, which handles 1.3 million packages coming into the country each day.
