Why the opioid epidemic may have fueled America’s murder spike

Over the past few years, America saw its murder rate rise — in 2015, 2016, and, according to the most recent data, the first half of 2017. Meanwhile, an opioid epidemic has led to the deadliest drug overdose crisis in US history — with nearly 64,000 drug overdose deaths in 2016 (at least two-thirds of which were linked to opioids), up more than 20 percent from the more than 52,000 drug overdose deaths in 2015.
