The quality of the photocopy is a little low, but the FDA’s Establishment Inspection Report (EIR) for the Duragesic Fentanyl patch factory in Vacaville, California sheds some light on (a) why there needed to be a recall of so many defective fentanyl patches, and (b) why so many people died from defective patches.  This document was produced during the discovery process in a Duragesic lawsuit.  If it weren’t for fentanyl lawyers finding documents like this, the public might never have known why so many patches had to be recalled.

Here’s the entire Establishment Inspection Report from this fentanyl lawsuit in PDF format.
