This doesn't help them at all, only lose profits when people don't throw away drugs anymore to buy new ones. ...

Unlike expired foods, which can be full of bacteria and fungi after the expiration, most drugs are good for at least 10 years after the expiration date. The reason they don't have longer expiration dates is that drug companies have to prove effectiveness beyond that time, which cost them a lot of time and resources to test. And why would they want to test for longer expiration dates? This doesn't help them at all, only lose profits when people don't throw away drugs anymore to buy new ones.

Many of our expired drugs go overseas, especially to Africa. Many are simply thrown away because we have too much money and paranoia to take expired drugs.

I'm not saying this from a conspiracy theory, either. Got this from a medical professor. ...
