"Marc Young, a pharmacist who helped run the extension program from 2006 to 2009, says it has had a “ridiculous” return on investment. Each year the federal government saved $600 million to $800 million because it did not have to replace expired medication, he says.
An official with the Department of Defense, which maintains about $13.6 billion worth of drugs in its stockpile, says that in 2016 it cost $3.1 million to run the extension program, but it saved the department from replacing $2.1 billion in expired drugs. To put the magnitude of that return on investment into everyday terms: It’s like spending a dollar to save $677."
