It's not illegal to smoke, but I think it is widely accepted that were the practice/drug had been introduced for the first time now it would be an illegal drug. It is antisocial in that it affects those around the smoker so a large portion of the present population has had enough. So it should be no surprise at all that governments want folk to behave better towards their fellow citizens and not continue to risk their health too.
As for alcohol, if it was introduced now it would probably also be illegal, but at least it is excess imbibing that causes issues, both short term for those around them, and longer term for themselves. And in small quantities it is an aid to sociability. Even so it is also subject to laws, which is fair enough.
As for the other problems mentioned I'm unsure why they are. Do you think all these things are in competition with each other ? That if you smoke you can't cause a road death, or if you drink you can't commit domestic violence ? You seem to be muddying any points you are trying to make so one can not see what you are getting at.
