Last night I played in a venue that i work in on a regular basis with my band and a few others,in fact the last time I was there was NYE. Since Jan 1st Chicago has started a smoking ban. This was something that I have been looking forward to for a long time because as a non smoker who works in a lot of clubs and has for many years I worry about the effect's of second hand smoke on my long term health.In fact the singer in my band my band who is a very successful jingle/voice over artist basically refused to work that room until after the ban took affect because the smoke was so bad.last night was great from that perspective although you still can smell the residue. Many of the employees of the club ,who are all heavy smokers,were not happy about the ban saying that it would cost them business. I have worked in New York,LA and Toronto and they all have no smoking and seemed to do ok so i don't know what there talking about. I know that as i sit here writing this I feel much much better than I usually do after playing a night in that club,for some reason the first night always makes me feel pretty rough the next day from the smoke.so my question is;Do you you have a smoking ban in your city and if so have you seen any effects good or bad from it?
