I don't understand this separation of individualised vices. What's the difference when society allows you to eat 10 large pizzas a night, become diabetic and obese, and the State will treat the diabetes? What's the difference when society allows you to smoke 5 packs of cigs a day, get lung cancer, and the State will treat that cancer? What's the difference when society allows you to drink 5 bottles of bourbon a night, kill your liver, and the State will attempt to find you another liver? And please remember: alcohol is a drug. A very very bad drug.
