Lee Cantrell, an associate professor of clinical pharmacology at the University of California, San Diego, with a collection of vintage expired medications. Sandy Huffaker for ProPublica hide caption. The box of prescription drugs had been forgotten in a back closet of a retail pharmacy for so long that some of the pills predated the moon landing.
