The concept of disease is fast replacing the concept of responsibility. With increasing zeal Americans use and interpret the assertion "I am sick" as equivalent to the assertion "I am not responsible": Smokers say they are not responsible for smoking, drinkers that they are not responsible for drinking, gamblers that they are not responsible for gambling, and mothers who murder their infants that they are not responsible for killing. To prove their point — and to capitalize on their self-destructive and destructive behavior — smokers, drinkers, gamblers, and insanity acquitees are suing tobacco companies, liquor companies, gambling casinos, and physicians.
