Stringsinger you made a clear statement that "since smoking second hand smoke is an occupational hazard for musicians ....."

That statement is incorrect. I repeat it is not an occupational hazard for musicians, nor has it been since 2007.

I do not argue that smoking has harmful effects or that musicians who played in pubs and clubs prior to 2007 may have suffered negative effects from passive/second hand smoke. However the truth of the matter is that (non-smoking)musicians are no longer subject to such hazards.

Fact, my friend, fact.
