Do you really want to go there?

Going on that logic, with the passage of this law, smokers who wish to smoke while enjoying a drink or food are forced to go to "underground" establishments (prohibition, speakeasies, what?). What say you?

As for this:

There is no philosophical or Constitutional reason a State can't choose to regulate time and place with smoking - where's the Constitutional prohibition.

No philosophical reason? Are you kidding me? So then you would agree with the statement that there is no philosophical or constitutional reason the state couldn't ban smoking? Would you also agree with the statement that there is no philosophical or constitutional reason the state couldn't place arbitrary restrictions upon the use of private property?
