Smoking is an addiction and one of the most preventable causes of premature death in the U.S. Smoking cigarettes exposes the smoker to over 4,000 chemicals, many of which are toxic. Smoking causes the vast majority of cases of lung cancer. Smoking also cause other cancers, including mouth cancer, kidney cancer, esophagus cancer, throat cancer and pancreas cancer. Smoking also causes or worsens other lung diseases. People close to a smoker can also experience similar effects due to the inhalation of second-hand smoke.
Dangerous toxins found in cigarettes include formaldehyde and cyanide. Another harmful substance is nicotine. Nicotine is an addictive drug whose side effects include raising heart rate, irritates blood vessels, and raises the risk of developing blood clots. This results in increased risk of cardiovascular disease, heart attack and stroke.
Another dangerous substance produced by smoking is carbon monoxide, which lowers the amount of oxygen in the blood. Smoking also constricts blood vessels. Smoking complicates asthma and other lung diseases, raises cholesterol, and can lead to life-threatening blood clots in women who take oral contraceptives (The Pill).
Because of the addictive nature of smoking, quitting is a difficult challenge. However, it is one of the best things smokers can do for themselves, their health, and their family and friends. Quitting smoking is also known as smoking cessation.
The rewards of successful smoking cessation are many and include a longer life. This is because one in three smokers dies early due to diseases that can result from smoking, such as emphysema, heart disease, lung cancer, and chronic obstructive pulmonary disease (COPD), according to the American Lung Association. Smoking cessation significantly decreases the risk of developing these serious lung diseases and cardiovascular diseases.
Smoking cessation improves the health of the lungs and increases respiratory capacity. This is the ability to take in oxygen, and people who quit smoking quickly experience less shortness of breath with activities and feel less fatigued and have more energy. Another important benefit of smoking cessation is the improvement in vital signs, including decreased blood pressure and pulse, and an increase in oxygen in the blood. The amount of carbon monoxide also drops in the blood after smoking cessation.
Because smoking constricts blood vessels and negatively affects circulation, smoking cessation is very beneficial for people who have other serious diseases, such as diabetes, which also damage blood vessels.
