According to the Centers for Disease Control and Prevention (CDC), diseases caused by smoking kill more than 480,000 people in the U.S. each year. In fact, smoking is directly responsible for almost 90% of lung cancer and COPD deaths. Even with antismoking campaigns and health warnings, many people continue to smoke or start to smoke every year. About 8% of kids under the age of 18 years are current tobacco users.
Smokers not only increase their risk of lung disease, including lung cancer, but they also increase their risk of other illnesses, including heart disease, stroke, and oral (mouth) cancer. Risks from smoking, as they relate to lung disease, include the following:
Chronic obstructive pulmonary disease (COPD) which includes:
Chronic bronchitis. Chronic bronchitis, a long-term inflammation of the bronchi (large airways), is characterized by coughing mucus over a long period.
Emphysema. Emphysema, a chronic lung condition that affects the air sacs in the lungs (alveoli), is characterized by shortness of breath, coughing, fatigue, sleep and heart problems, weight loss, and depression.
Lung cancer. Lung cancer, an abnormal, growth of cells that can result in lumps, masses, or tumors, It may start in the lining of the bronchi (large airways), or other areas of the respiratory system. Symptoms of lung cancer include a cough, chest pain, shortness of breath, wheezing, recurring lung infections, bloody or rust-colored sputum, hoarseness, swelling of the neck and face, pain and weakness in the shoulders, arms, or hands, and unexplained fever. Smoking, including secondhand smoke, is the leading cause of lung cancer.
Other cancers. Not only does smoking increase the risk of lung and oral cancer, it also increases the risk of other respiratory system cancers including cancer of the nose, sinuses, voice box, and throat. And, smoking increases the risk of many other cancers of gastrointestinal, urinary, and female reproductive systems.
The symptoms of smoking-related lung diseases may look like other lung conditions or medical problems. If you have any symptoms of lung disease, see your health care provider as soon as possible.
Secondhand smoke is smoke that is exhaled by smokers and smoke emitted from the burning end of a lit cigarette, cigar, or pipe. It causes more than 7,000 lung cancer deaths each year in persons who do not smoke. It can also lead to lung conditions and heart disease. Symptoms associated with exposure to secondhand smoke may include:
Irritation of the eyes, nose, and throat
Excessive mucus in the airways
Chest discomfort or pain
Children and infants exposed to tobacco smoke are more likely to experience ear infections, and asthma. They are also at a higher risk for sudden infant death syndrome (SIDS) than children and infants not exposed to secondhand smoke.
People who quit smoking can actually reverse some of the lung damage. Other benefits of quitting smoking may include the following:
Decreased risk for lung disease
Decreased risk for heart disease
Decreased risk for cancer
Reduced cigarette stains on fingers and teeth
Reduced occurrence of cough
Elimination of stale cigarettes smell on clothing and hair
Improved smell and taste
Saving money by not buying cigarettes
Cigars actually pose the same, if not greater, risk as cigarettes for oral cancer. Although many cigar smokers do not inhale, their risk for oral, throat, and esophageal cancers is the same as for cigarette smokers. Consider these facts from the CDC:
Compared with nonsmokers, cigar smokers who inhale are more likely to develop oral cancer, esophageal cancer, and laryngeal cancer.
Cigar smokers who inhale and smoke five cigars a day may have a lung cancer risk similar to one-pack-a-day cigarette smokers.
Secondhand smoke from cigars contains toxins and cancer-causing agents (carcinogens) similar to secondhand cigarette smoke, but in higher concentrations.
Quitting smoking is very difficult. The American Academy of Otolaryngology and the American Lung Association offer the following tips to help users quit using tobacco products:
Think about why you want to quit. Make a list of the reasons.
Set a quit date.
Try to pick a time when you have as little stress as possible.
Ask for support and encouragement from family, friends, and coworkers.
If you don't already exercise, start to increase your physical activity to improve your health.
Try to get enough sleep each night and eat healthy. Along with exercise, healthy sleeping and eating will help you cope with quitting.
Join a smoking cessation program, or support group. These programs are available in most communities. And, there are also programs available by phone and Internet.

There are both prescription and over-the-counter medications that can help you stop smoking. Talk with your health care provider about these medications and whether or not any of them are right for you.
Nicotine patch. Nicotine is delivered through the skin.
Nicotine gum. Gum delivers nicotine quickly.
Nicotine lozenge. Lozenges are like hard candy.
Nicotine nasal spray. Nicotine is also delivered quickly.
Nicotine inhaler. Using an inhaler is like smoking cigarettes.
Zyban (bupropion). It helps to lessen cravings for nicotine.
Chantix (varenicline tartrate). It helps to lessen the discomfort of quitting and the pleasure you get from smoking.
