Plus, pretty much every Ron Paul supporter I've met here can be reduced to 'ZOMG LEGAL POT HURRDURR'
It's a stupid assertion that people only support RP for his support for legalized marijuana. Maybe those are the people you've met, I can't speak for your experience - but you can't make those generalizations.
His actual position is a constitutional position, states have a right to regulate it in their own way.
His PERSONAL position is though that there should be no paternalistic government laws, such as seat belt laws, drug/alcohol prohibition or anything like that. It's not the role of the government to mold behavior.
I have never seen or touched drugs nor will I ever consume them yet I support the legalization of all drugs. The effects are going to be only positive. Saving large amounts of money in the criminal justice system, as well as there being an easier method for rehab groups to reach out to abusers. The way drug laws are being enforced is also RACIST. Ron Paul would STOP that. Blacks make up something like 1/7 of drug users but over half of those incarcerated for non-violent drug offenses are black.
Plus, if we're going to draw any conclusions from Portugal, a country that legalized all hard drugs a few years back, it's that the number of deaths from overdoses have dramatically decreased. They have not decriminalized the sale of drugs though, which they should have.
I strongly believe that inner city major crime, including homicide, would drastically decrease if distribution and usage of drugs were fully legal.
