What are three ways in which tobacco use affects the respiratory system?

Is this question multiplc choice or open-ended? Anyways, I'll give you some ideas.

-Chronic obstructive pulmonary disease, a disease that gets worse over time and causes wheezing, shortness of breath, chest tightness, and other symptoms.

-Pneumonia

-Chronic Bronchitis, which causes swelling of the lining of your bronchial tubes. When this happens, less air flows to and from your lungs.
