Smoking also causes coronary disease, stroke, aortic aneurysm (an inflatable lump in a chest artery), chronic obstructive pulmonary disease (COPD) (constant bronchitis and emphysema), diabetes, osteoporosis, rheumatoid joint inflammation, age-related macular degeneration, and waterfalls, as well as destroying asthma symptoms in adults. Smokers are more likely to contract pneumonia, TB, and other diseases. When you quit smoking, it increases aggravation and reduces the invulnerable capacity.
