Father smoked for a while he quit, he has had a cough for a long time and in the morning when he wakes up his voice is rough. is this normal does everyone have rough voice / cough from smoking or should i be worried?

Smoking may result in a number of pulmonary conditions. It is very good that he quit. Provide support and check with your local lung association to continue his smoking cessation. Avoid second hand smoke. An oral and pulmonary examination are indicated. PFTs and a chest radiograph may be discussed at the time of the visit. Watch for blood in any mucus expectorated, and if this occurs, the ED.
