I don't completely agree with the article's message. I think people who deal with statistical quantities of product and do extensive quality control testing probably have some wisdom about what's really safe. The article refers to a paper (which I've skimmed) that leaves a bunch of unanswered important questions.
I would push two prongs: reinforce that expiration dates are serious, and at the same time test and extend any/all dates to the actual behavior of each drug. turn a one year into 5, 10, 20? Hell yes.
Pretty obvious that big chunks of the health care system are rigged for profit, not efficiency or usefulness.
