With all the other news going on, it can be easy to lose track of this fact. But it's true: In 2015, more than 52,000 people died of drug overdoses, nearly two-thirds of which were linked to opioids like Percocet, OxyContin, heroin, and fentanyl. That's more drug overdose deaths than any other period in US history — even more than past heroin epidemics, the crack epidemic, or the recent meth epidemic. And the preliminary data we have from 2016 suggests that the epidemic may have gotten worse since 2015.
This situation did not develop overnight, but it has quickly become one of the biggest public health crises facing America. To understand how and why, I've put together a series of maps and charts that show the key elements of the epidemic — from its start through legalpainkillers prescribed in droves by doctors to the recent rise of the highly potent opioid fentanyl.
