Actually it might surprise you.
Being around smokers and smelling the smoke hurts more than smoking it yourself. So yea somehow you must take care of this matter in a right way before your voice chords gets damaged slowly.
how much does staying with smokers affect health and especially does smelling the smoke affect my voice if I'm someone who cares about his voice and sing alot?
I had a roommate that was a smoker. After living with her a few months I developed bronchitis. I went to the doctors got treated. It came back a few weeks later. This cycle continued for about 6 months at which time my doctor told me to move out. I did. No more bronchitis, but I had to wash everything I owned because it all smelled like smoke even though she never smoked in my room. While I was never a singer, it surely effected my breathing and throat.
Second hand smoke is almost as bad as smoking yourself ! It will affect you almost as bad. I would sure do my best to get away from it as soon as possible.
I was raised by smokers and it seemed as tho I always had a cough or a stuffy nose. When I left home for the Navy, the stuffy nose ansd the recurring cough magically disappeared.
