I'm a big fan of the free market. I guess that point would have been better stated that drug money making empires rubs me wrong. But then, so does Tom Hanks or Harrison Ford getting $20 mill to make a movie, when a single cop or a fireman is worth ten times those silly Hollywood dorks. But I wouldn't change the system, I'd try to change the hearts of people.
My approach as well because attempting to legislate away personal choice causes way, way more problems than drug use ever would. Education, persuasion, appeal to reason work. Telling people, "Because I say so," usually has exactly the opposite result of what was intended.
