Chronic obstructive pulmonary disease-copd (emphysema and bronchitis) deaths. If the cilia are covered in tar, they can"t do their job properly, and germs, chemicals and dirt can stay in your lungs and cause disease-cancer. It is not the nicotine that is the health hazard (nicotine causes the addiction), it is the tar that covers the cilia. Smoking and chronic obstructive pulmonary disease (copd: smoking permanently damages the alveoli (air sacks) in the lungs, making it harder to breathe, the alveoli are built like tiny, stretchy balloons. Smoking and death: tobacco kills about 37,000 canadians a year, tobacco kills about 480,000 americans a year. 15-20% of people smoke on a regular basis. The higher income, the less likely you are to smoke.
