Smoking is also the leading cause of coronary heart disease, stroke, and many other cancers and illnesses.1 See more about health effects caused by smoking. Cigarette smoking alone increases your risk of developing coronary heart disease; the heart of a smoker is between two and four times as likely to develop coronary artery disease as the heart of a non-smoker .
Cigarette smoking impacts the respiratory system, circulatory system, reproductive system, skin, and eyes, and increases the risk for a number of different types of cancers. Cigarette smoking also increases your risk for lung and heart diseases, like chronic obstructive pulmonary disease. Smoking also increases the risk of lung infections like pneumonia and tuberculosis, and can make certain existing lung diseases, like asthma, worse. Even if you only smoke one cigarette per day, this has significant health consequences.
Smoking also has an impact on your insulin, making you more likely to develop insulin resistance. Smoking does not just affect your cardiovascular health -- it affects the health of people around you who are not smoking. Cigarette smoking causes inflammation and cellular damage across your body, as well as weakening your immune system, making you less able to fight disease. In fact, according to the Centers for Disease Control and Prevention (CDC), cigarette smoking increases the risk of death from all causes, not just from those related to tobacco pipe use.
In addition to the known risks to developing cancer, smoking causes a number of other chronic (long-term) health problems, which require continuous treatment. Womens risk of smoking-related diseases has increased dramatically in the past 50 years, now matching that of men, with respect to lung cancer, COPD, and heart disease. Smoking damages almost every organ in the body, and is a leading cause of lung cancer and COPD. Smoking is directly responsible for about 90% of lung cancer deaths, and about 80% of deaths caused by chronic obstructive pulmonary disease (COPD), including emphysema and chronic bronchitis.
Fifty percent of all smokers die from smoking-related diseases, and life expectancy of 1 in 4 smokers is reduced by up to 15-20 years . Smoking also significantly increases the risk of heart diseases, including stroke, heart attack, cardiovascular diseases, and aneurysm.51,52 Cardiovascular diseases are responsible for 40% of all smoking-related deaths.53 Smoking causes coronary heart disease, which is one of the leading causes of death in the U.S. Cigarette smoking causes decreased circulation, narrowing the vessels (arteries), and puts smokers at risk of developing peripheral vascular disease (i.e., blockages in major arteries of the arms and legs, which can cause a number of problems, ranging from pain to tissue loss to gangrene). Cigarette smoking also increases blood pressure, weakens blood vessel walls, and increases the number of blood clots.
Recent studies found that cigarette smokers who smoke only one cigarette per day had almost half the risk of developing coronary heart disease and stroke as those who smoked 20 cigarettes per day. Tobacco use also causes many other diseases, and it can harm almost every organ in the body, including your lungs, heart, blood vessels, reproductive organs, mouth, skin, eyes, and bones.
