Williamson, W.Va., sits right across the Tug Fork river from Kentucky. The town has sites dedicated to its coal mining heritage and the Hatfield and McCoy feud and countsjust about 3,000 residents.

But despite its small size, drug wholesalers sent more than 20.8 million prescription painkillers to the town from 2008 and 2015, according to an investigation by the House Committee on Energy and Commerce. The opioids — hydrocodone and oxycodone pills — were provided to two pharmacies just four blocks apart.
