Isn't that the truth. Another example came to mind immediately which is the treatment of alcoholism. AA is really big in the United States but has abysmal recovery rates, whereas preliminary studies with muscle relaxants have shown great promise.
Yet in public discourse diseases are treated like one's 'personal demons', a 'challenge that has to be overcome' and so on. It almost seems like a personal growth lifestyle change rather than an objective medical assessment with programs like AA suggesting opening oneself up to 'higher powers' in their official guidelines.
There really needs to be a big culture shift that moves health debate from a sort of Puritanism to objective medical evaluation that keeps the personal angle out. Especially when it comes to drug abuse and dietary related illnesses. Obesity is a big issue as well.
