A ProPublica video reports on a year-long investigation by Debbie Cenziper and Megan Rose into foreign-made generic drugs — 90% of what Americans take — finding lab-tested tacrolimus pills with too little active ingredient, factory record manipulation, and FDA secret deals exempting banned plants during drug shortages. The piece ties this to Hannah Goetz, who died at 21 after rejection despite two versions of the drug, and offers its Rx Inspector tool for looking up a pill's factory.
