Drinking affects others much more than smoking does, it's just that it doesn't affect random strangers. In a study of the harms of various substances, alcohol came out on top by a mile for the damage it does to the family and others close to the drinker.

I should qualify the above: it doesn't affect random strangers as often as second-hand smoke does. But drunk driving and drunk violence are a thing, and both can affect anyone.
