COPD is an auto-immune disease that reacts to the pollution of even one single cigarette! It doesn't care if you are young or old! It doesn't care if you are a closet smoker or a walking chimney! It doesn't care if you smoke one a week or 3 packs a day! If you smoke AT ALL - you risk cancer, heart disease, stroke, bronchitis and emphysema! COPD is simply a combination of 2 of the following: Asthma, Bronchitis, Emphysema or Alpha 1 (hereditary respiratory obstruction)! So if you already grew up with Asthma then you were already 1/3 of the way there! People with Asthma are playing with fire! Don't ever think it can't happen to me because the truth is it CAN! If you have been diagnosed, don't despair! Quitting Smoking is the single BEST way to slow the progress of the disease! TODAY is a Great Day to Quit Smoking!
