Apples and oranges. There isn’t any way to compute a fully accurate exchange rate. I’m more averse to smoking (never smoked anything) than drinking in moderation. Though there’s no way to equally measure consumption, I think smoking is more likely to cause lung cancer, emphysema, etc., and it makes you and your surroundings smell and taste like stale cigarette smoke. Alcohol can also get you killed in various ways (drunk driving, falling, fighting, bad mistakes, and when overused chronically, organ disease), but in moderation is not really unhealthy. But alcoholics can have terrible behavior problems which can lead to domestic violence, depression, unemployment, etc. I’d want the alcoholic to get help first if they are having behavior problems. Then I’d want the smoker to try to quit.
