Diseases caused by smoking kill more than 438,000 people in the US each year. In fact, smoking is directly responsible for the majority of lung cancer cases (87 percent), emphysema cases, and chronic bronchitis cases. Even with anti-smoking campaigns and medical health disclaimers in place, many people continue to smoke or start to smoke every year. Over 1,100 teenagers younger than age 17 become regular smokers each day.
Smokers not only increase their risk of lung disease, including lung cancer, but they also increase their risk of other illnesses, including heart disease, emphysema, stroke, and oral cancer. Risks from smoking, as they relate to lung disease, may include, but are not limited to, the following:
The symptoms of smoking-related lung diseases may resemble other lung conditions or medical problems. Always consult your physician for a diagnosis.
Secondhand smoke, smoke that is exhaled by smokers and smoke emitted from the burning end of a lit cigarette, cigar, or pipe, causes nearly 3,000 lung cancer deaths each year in persons who do not smoke themselves. Also called involuntary or passive smoking, secondhand smoke can also lead to heart disease. The following are some of the most common symptoms associated with exposure to secondhand smoke. However, each individual may experience symptoms differently. Symptoms may include:
Children and infants exposed to tobacco smoke are more likely to experience ear infections, and asthma, and are at a higher risk for sudden infant death syndrome (SIDS) than children and infants without the same exposure.
The symptoms of secondhand smoke may resemble other medical conditions and problems. Always consult your physician for a diagnosis.
People who quit smoking can actually reverse some of the damage that has been done to their lungs over an extended period of time. Other benefits of quitting smoking may include the following:
Cigars became a trend in the 1990s, attracting the young and the old. Perceived as less detrimental to one's health, 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:
Zyban®, a non-nicotine alternative to help people stop smoking, was approved in 1996 by the US Food and Drug Administration (FDA). Offered to smokers who want to quit, Zyban (Bupropion HCI), in pill form, has been shown to alter mood transmitters in the brain that are linked to addiction. Zyban must be prescribed by a physician and may not be appropriate for everyone. Consult your physician for more information.
There is another new smoking cessation medication approved by the FDA called Chantix® (varenicline) that has been available in the US as of 2006. This medication works differently than any of the other nicotine replacement products or Zyban. Chantix affects the nicotine receptors in the brain, decreasing nicotine cravings and withdrawal symptoms, and making smoking less pleasurable. It is available only by prescription. In early studies, Chantix appears to be even more effective than Zyban in helping people stay smoke-free. Talk to your physician for more information.
Quitting smoking is both a mental and a physical undertaking. Mentally, you should be ready and relatively stress-free. Physically, you need to commit to exercising daily and getting plenty of sleep. A person trying to quit must overcome two obstacles: a physical addiction to nicotine and a habit. The American Academy of Otolaryngology and the American Lung Association offer the following tips to help users quit using tobacco products:
In some cases, smokers benefit from nicotine replacement products to help break their smoking habit. Nicotine replacement products continue to give the smoker nicotine, although in smaller quantities than a cigarette, to meet their nicotine craving. However, the benefit of nicotine replacement products is the elimination of tars and poisonous gases that cigarettes emit. Pregnant or nursing women, and people with other medical conditions, should consult with their physician before using any nicotine replacement products. Some examples of nicotine replacement products include:
