Over the past decade, nearly 21 million prescription painkillers have been shipped to a tiny town in West Virginia, a state where more people have overdosed on opioids and died than in any other in the nation.

The House Energy and Commerce Committee, which has been investigating the opioid epidemic, revealed that 20.8 million hydrocodone and oxycodone pills have been delivered to Williamson, West Virginia, a town with a community college, a rail yard – and fewer than 3,200 residents, according to the most recent Census figures.

That’s more than 6,500 pills per person – though not all of the painkillers stayed in Williamson.

As the Charleston Gazette-Mail reported, committee leaders sent letters to two regional drug distributors, asking why the companies oversupplied this town, among others, with painkillers. “These numbers are outrageous, and we will get to the bottom of how this destruction was able to be unleashed across West Virginia,” Reps. Greg Walden, R-Ore., and Frank Pallone Jr., D-N.J., said in a statement, according to the Gazette-Mail.

A 2016 investigation by the Gazette-Mail shed light on the issue in West Virginia – and The Post reported last year that a new legal front has opened in the war against the opioid crisis, as attorneys in the state began to file federal lawsuits targeting some of the nation’s largest distributors

Tug Valley Pharmacy declined to comment. But Nicole McNamee, the owner of Hurley Drug Company, said that while the numbers may seem disproportionate, the two pharmacies have to cover a large service area:
