The World According to Tyler Cowen

"You have people smoking marijuana and taking cocaine, pretending it’s a semi-acceptable thing. I think people should just voluntarily treat it like the plague. It’s not a great solution, and a lot of the technical fixes—like changing electronic medical records so we know who is over-prescribing, and who has gotten what from other doctors—will only solve the problem a bit. But we should do them all. 

I think addiction is an underrated issue. It’s stressed in Homer’s Odyssey and in Plato, it’s one of the classic problems of public order—yet we’ve been treating it like some little tiny annoyance, when in fact it’s a central problem for the liberal order."
