What happens when the states pass laws banning smoking in public. It then becomes illegal.
No, the commodity is still legal. Go to California. You can still buy cigarettes, tobacco, rolling papers (Haaaaaa), cigars, etc.
And it should STILL be up to the business owner/manager as to allow, or disallow, smoking in their business but the anti-smoking cabal has, once again, used junk science, scare tactics, and in this case, the California health nuts to get laws passed that shouldn't even be on the books.
