Do you get a deeper voice from smoking?

It sure can! In most cases permanent changes to voice would happen over a period of several years of smoking. However routine smoking can cause a person to have periodic episodes of hoarseness esp with bronchitis or "colds." If you smoke and have a sudden change in your voice that lasts more than several days have it checked out by your doctor as it could be serious, for example a tumor or polyp in your throat or voice box (larynyx.)
