On May 1, the "Smoke-Free Arizona Act" went into effect. The law bans smoking in all public places, including restaurants, bars and common areas. Tribal areas are sovereign lands and therefore exempt. That means even more $$$ for the Indian casinos - the last refuge for folks with petty vices.
I don't smoke, but I do use the stairwell as a shortcut to the food court. Thus, I may well be the first collateral casualty in Arizona's global war on smoking.
