There are acceptable threshold limit values on every chemical in
cigarette smoke but they do not apply if the source is cigarette
smoke.
I'm pro freedom. I've stated here in this thread many, many times. I
don't care how much someone smokes. Get your kids to smoke. Take them to
the smoking lounge at the airport, I don't care.
BUT, smokers are DIRECTLY harming the health of innocent people. THAT is
the problem.
