There is no comparison between tobacco smoke found in even the smokiest of bars or nightclubs and the smoke found in a typical house fire. If you want to ask a firefighter (which is what they prefer to be called) about this, you just did.
On behalf of every fireman in the U.S. thanks for your opinion. Look, if you want to claim that smoke is good for us go ahead. I did not make the claim that the smoke produced by cigarettes is the same as smoke in your average house fire. What I did say was that smoke is the number one killer in fires and that smoke is not good for human lungs. If you wish to dispute that, be my guest.
