You do realize that in many, many countries, you can buy antibiotics over the counter, right? Nearby countries like Mexico, and far away countries like India (with a huge population)? And that people are buying them and using them constantly?
Sure, there's the risk of antibiotic resistant bacteria developing, but the U.S. isn't going to stop that from happening no matter how difficult they make it for people to buy and use the drugs they need.
I'm starting to lose patience with people trying to take away the right of other people to control their own body.
And it's not just antibiotics. Things like prescription drugs being essentially purposefully laced with poison (acetaminophen) to prevent people from "abusing" them and other drugs like cannabis being illegal is utterly ridiculous.
If we don't own our own bodies, what do we get to own?
