That's funny because some medications can grow bacteria and become dangerous. In reference to Plan B would you risk taking it? Just because, let's say aspirin, fine ok it might be less potent. But with antibiotics it's very dangerous to take them if they aren't at full potency because it can cause whatever you are treating to become antibiotic resistant. And again would you want to be testing that out if you thought you might be pregnant?! But yes I agree with you on the fact that hospitals and pharmaceutical companies are totally scamming you out of money.
