Q. Is it possible to keep singing if you're a smoker?

A. Yes. However, smoking has certain effects on your body which will affect your singing:


Smoke burns the cilia that line the airways to your lungs. These cilia protect the suface they line from infection. In addition, without these cilia lining your airways, you will likely begin to experience a retention of fluid in your lungs because the mucus created in your nose and elsewhere will continually slide down your windpipe.
You will find yourself short of breath not only because of fluid in your lungs, but because the smoke burns, turns black, and destorys your alveolar, the air sacs in your lungs. Less of them means less air, the exact thing you need to have to sing.
