Secondhand smoke is never safe at any level

The U.S. Surgeon General released a report that says there is no safe level of second-hand smoke.

"...even a few minutes inhaling someone else's smoke harms nonsmokers, he found. And separate smoking sections, even the best ventilated ones, don't protect enough. Carmona called for completely smoke-free buildings and public places to lessen what he termed "involuntary smoking."

So the discussion is over, except from the tobacco companies. Now it is just a case of outlawing smoking in all public places and educating the ones who smoke at home. The latter should include helping everyone who is hooked on smoking break the addiction.
