My statement is from personal experience, knew a lot of musicians, can you prove otherwise. ?
I hate getting distracted by all this smoking vs anti-smoking bullshit, but I can't bear ignorance.
I have played the piano at a high professional level for 36 years. Most of the musicians with whom I have performed do not smoke, but are not anal about it. I guess the total number involved here is approximately 83, 70 of whom do not smoke. However, they do not view the other 13 as either pariahs or people that they'd rather not be around.
The musicians of my acquaintance have more important things to do than be concerned about smoking.
