McKinsey never told the FDA it was working for opioid makers while also working for the agency

Since 2008, McKinsey & Company has regularly advised the Food and Drug Administration’s drug-regulation division, according to agency records. The consulting giant has had its hand in a range of important FDA projects, from revamping drug-approval processes to implementing new tools for monitoring the pharmaceutical industry.

During that same decade-plus span, as emerged in 2019, McKinsey counted among its clients many of the country’s biggest drug companies — not least those responsible for making, distributing and selling the opioids that have ravaged communities across the United States, such as Purdue Pharma and Johnson & Johnson.
