Eh? Cigarettes kill ten times as many people as alcohol.

That is why I had my little disclaimer at the bottom...

If we are just talking effect on the user then Alcohol isn't nearly as bad as cigarettes but if we are talking about the user affecting other people than aside from a bad smell it is unlikely a smoker will affect you negatively*

*If you were to spend a lifetime performing in smoking clubs though then you would have to reverse it again but I can't imagine there are many people at all especially in our rich western democracies who are going to die of inhaling the cigarette smoke of other people only...
