- smoking causes coronary heart disease, the leading cause of death in the United States and other parts of the world.
- Cigarette smoking causes reduced circulation by narrowing the blood vessels (arteries) and puts smokers at risk of developing peripheral vascular disease (i.e., obstruction of the large arteries in the arms and legs that can cause a range of problems from pain to tissue loss or gangrene)
Peripheral Vascular Disease
Smoking causes lung cancer. Smoking causes lung diseases (e.g., emphysema, bronchitis, chronic airway obstruction) by damaging the airways and alveoli (i.e., small air sacs) of the lungs. The effects of smoking on human health are serious and in many cases, deadly. There are approximately 4000 chemicals in cigarettes, hundreds of which are toxic. The ingredients in cigarettes affect everything from the internal functioning of organs to the efficiency of the body’s immune system. The effects of cigarette smoking are destructive and widespread.
The effects of smoking on your heart are devastating. Nicotine raises blood pressure and makes the blood clot more easily. Carbon monoxide robs the blood of oxygen and leads to the development of cholesterol deposits on the artery walls. All of these effects add up to an increased risk of heart attack. In addition, the poor circulation resulting from cholesterol deposits can cause strokes, loss of circulation in fingers and toes and impotence.
The digestive system is also affected. The tars in smoke can trigger cancer of the esophagus and throat. Smoking causes increased stomach acid secretion, leading to heartburn and ulcers. Smokers have higher rates of deadly pancreatic cancer. Many of the carcinogens from cigarettes are excreted in the urine where their presence can cause bladder cancer, which is often fatal. High blood pressure from smoking can damage the kidneys.
