As a future medical professional I see this as absurd.
Some one doesn't like being cut out of the gravy train. BTW, has anyone here even heard of a single person you know EVER get sold fake antibiotics? Additionally antibiotics are a low margin product. Why would someone take all the time and money to counterfeit something that will sell for very little? Sounds to me like that is your medical indoctrination talking.
I'd rather have someone (Silk Road?) selling cocaine to anyone than selling strong antibiotics to anyone. Cocaine hurts the person who decides to use it, and his family, friends, perhaps strangers (if the user becomes violent)... but it does not threaten society as a whole.
Antibiotics do. Every time someone takes antibiotics, the possibility of antibiotic-resistant bacteria evolving approaches 1. Antibiotics have their uses, certainly. But they NEED to be regulated. The average person can't tell if they have a viral or a bacterial disease. So if they order amoxicillin online, take it, and get better in a week or so, they promptly associate amoxicillin with the disappearance of their ilness.
Already we're seeing MRSA and XRSA... and when bacteria become immune to a drug, that drug becomes worse than useless. There are a limited number of possible antibiotics, an even tinier number of /effective/ antibiotics.
