Has this drug reached its expiration date?

If so, we - and more sophisticated users such as hospitals - throw it out. But the federal government does not necessarily do so, as the drugs are still useful for their intended purposes. For decades, the federal government has stockpiled massive stashes of medication, antidotes and vaccines in secure locations throughout the country. The drugs are worth tens of billions of dollars and would provide a first line of defense in case of a large-scale emergency.It spends a lot of money to do so but the roi is quite high, like $677 saved for every dollar spent.
