The giants at the heart of the opioid crisis

Three states — New York, Vermont and Washington — have recently filed civil suits against pharmaceutical distributors, accusing the companies of devising systems to evade regulators. They allege that the distributors warned pharmacies at risk of being reported to the Drug Enforcement Administration, helped others to circumvent limits on how many opioids they were allowed to buy, and often gave advance notice of audits.

The distributors reject the allegations. The companies named in the suits include Cardinal Health, McKesson and AmerisourceBergen, all three among the 15 largest American companies by revenue. Together, they distribute more than 90 percent of the nation’s drug and medical supplies.

Background: Since the painkiller OxyContin was introduced in 1996, there have been more than 200,000 overdose deaths related to prescription opioids, according to the Centers for Disease Control and Prevention. Overdose deaths continue to rise, but the number of opioid prescriptions has been falling since 2012.
