Smoking Causes Dangerous Diseases
Smoking is a precarious habit and recent studies show that smoking is directly or indirectly related to some form of health risk and disease. Lung cancer has long been identified as a result of smoking and smoking also has a hand in most other common ailments like heart disease and cancers. It was way back in 1962 when smoking was considered to be a direct contributor to bronchitis, lung cancers, duodenal ulcers and coronary heart disease. In 1979, this theory was further confirmed by studies, the results of which showed cigarettes to be the leading cause of numerous cancers including larynx, esophagus, lung and oral cavity. Cigarettes were also known to be a contributing factor for other cancers namely kidney, bladder and pancreas.
Now there is no doubt that smoking looks like the major cause of COPD which is the Chronic Obstructive Pulmonary Disease (a combination of chronic bronchitis and emphysema). Both men and women are at risk of COPD and even second hand smoking can be a cause of that. In fact second hand smoking can actually cause premature death in children and even some adults who have never once touched a cigarette. SIDS or Sudden Infant Death Syndrome is very common in children with parents who smoke. There can also be several other problems from second hand smoke including respiratory problems like asthma and respiratory infections. Second hand smoke can also cause ear, lung and cardiovascular problems in both young ones and adults.
In conclusion, first hand smoke and cigarette smoking is directly related to such problems like coronary disease and lung cancers while it is a contributing factor in blood pressure and a number of other cancers. Second hand smoke on the other hand, is indirectly related to SIDS and directly related to COPD.
