And no Emphysema!!! LOL - (of course - the hardened smokers will not want to read below)!!
Emphysema Causes:
Cigarette smoking is by far the most dangerous reason that people develop emphysema, and it is also the most preventable cause. Other risk factors include a deficiency of an enzyme called alpha-1-antitrypsin, air pollution, airway reactivity, heredity, male sex, and age.
The importance of cigarette smoking as a risk factor for developing emphysema cannot be overemphasized. Cigarette smoke contributes to this disease process in 2 ways. It destroys lung tissue, which is the cause of the obstruction, and it causes inflammation and irritation of airways that can cause the disease to get worse.
Destruction of lung tissue occurs in several ways. First, cigarette smoke directly affects the cells in the airway responsible for clearing mucus and other secretions. Occasional smoking temporarily disrupts the sweeping action of tiny hairs called cilia that line the airways. Continued smoking leads to longer dysfunction of the cilia. Long-term exposure to cigarette smoke causes the cilia to disappear from the cells lining the air passages. Without the constant sweeping motion of the cilia, mucous secretions cannot be cleared from the lower respiratory tract. Furthermore, smoke causes mucous secretion to be increased at the same time that the ability to clear the secretions is decreased. The resulting mucous buildup can provide bacteria with a rich source of food and lead to infection.
So give it up - save Loads'a money - live longer - smell sweeter!! Happy new year!
