"Want a bunch of health problems? Some asthma, blocked blood vessels, some lung disease – perhaps a little cancer? Neither do I." – Sarah Chalke, Scrubs
Currently, 20.9 percent of American adults, or 45.1 million people, smoke cigarettes, with a majority falling between the ages of 18-24. With nearly 6,000 children under 18 years of age trying cigarettes each day, education is becoming more important as younger kids experiment with smoking. Smokers not only harm themselves, but also put their family and friends at risk by exposing them to secondhand smoke. By saving someone from smoking, we can also reduce the risk to those around them, which will prevent millions of deaths per year.
Cigarettes contain over 4,800 chemicals, more than 60 of which are known carcinogens. In addition to the substances found in tobacco, manufacturers add hundreds of more chemicals, including arsenic, tar and carbon monoxide, in order to improve the taste of cigarettes. Because tobacco companies are not required to reveal the amount of each substance that is added to cigarettes, the health risk of these chemicals remains unknown.
Nicotine, the prominent drug found in tobacco, is highly addictive – as addictive as heroin or cocaine. When a person inhales cigarette smoke, nicotine enters into the lungs, where it is quickly absorbed into the bloodstream. The drug is then carried to all parts of the body, including the heart, blood vessels and brain.
Nicotine produces favorable feelings for smokers, creating a desire to smoke even more. It also acts as a depressant, impeding the flow of information passing between nerve cells. As the nervous system adapts to the nicotine, smokers increase the number of cigarettes they smoke in order to feel the same effects. Eventually, smokers reach a certain level of nicotine and then smoke in order to maintain that level.
Smokers not only become physically addicted to cigarettes, but also associate smoking with various social activities, making it even more difficult to quit. These habits are developed at a young age, as about 90% of smokers start before the age of 21. Family relationships also affect smoking habits; children of smokers are twice as likely to start smoking than children of non-smokers.
Cigarette smoking is the leading cause of preventable death worldwide. Each year, over 430,000 Americans die from smoking-related causes, making cigarettes more lethal than alcohol, homicide, suicide, AIDS, car accidents and illegal drugs combined.
Smoking causes about 30 percent of all cancer deaths and 87 percent of lung cancer deaths, the most common of cancer fatalities and one of the most difficult to treat. Cigarettes are a leading cause of other types of cancer, including larynx, esophagus, and bladder. Cancer accounts for only half of smoking-related deaths; smoking is also a major cause of heart disease, bronchitis, emphysema, and strokes. About 8.6 million people suffer from at least one chronic disease caused by smoking, costing the United States over $167 billion per year in health care costs. On average, male smokers lose 13.2 years of life while female smokers lose an estimated 14.5 years of life from smoking.
More visible effects of smoking include premature wrinkling of the skin, bad breath, yellow fingernails and blindness in the elderly. In women, smoking is also linked to reduced fertility, higher risk of miscarriage, premature delivery, stillbirth and low birth weight in newborns.
Secondhand smoke is a mixture of smoke coming from the end of the cigarette and the smoke that is exhaled by the smoker. Secondhand smoke contains more than 250 toxic chemicals and is responsible for over 3,000 lung cancer deaths and 46,000 heart disease fatalities each year.
More than 126 million Americans are exposed to secondhand smoke in the home, workplace and public areas. Non-smokers who are exposed to cigarette smoke increase their risk of lung cancer by 20-30 percent and heart disease by 25-35 percent. Even small amounts of secondhand smoke are harmful; smoke inhalation has immediate effects on the cardiovascular system and increases the risk of heart attack. Secondhand smoke can also cause chest discomfort and irritation of the eyes, throat, and lungs. So far, fifteen states have banned smoking in all public areas, including restaurants and bars.
Most of secondhand smoke exposure occurs in the home. In the United States, 21 million children are exposed to cigarette smoke, resulting in more ear infections and respiratory symptoms. Children exposed to secondhand smoke are also more likely to develop asthma and are at increased risk of sudden infant death syndrome.
70 percent of smokers want to quit, and while 35 percent attempt to quit each year, only 5 percent succeed. People who quit smoking at a younger age experience the greatest health benefits. Those who quit before the age of 30 can avoid most of the health risks associated with cigarettes. Yet, smokers who quit before the age of 50 still reduce their risk of dying within 15 years by one-half compared to those who continue to smoke.
Quitting smoking reduces the risk of lung cancer, stroke, heart disease and respiratory illnesses. More immediate benefits include a sharper sense of taste and smell, fewer ailments and improved respiratory function. Benefits of quitting are both physical and economical. A smoker who buys a pack a day will save about $700 per year, and with the increasing prices of cigarettes, these savings will only increase in the future.
The absence of nicotine causes both physical and mental effects, making it difficult for smokers to successfully quit. Withdrawal symptoms include dizziness, increased appetite, irritability, headache, restlessness and sleep disturbances. Those attempting to quit often begin smoking again in order to raise their nicotine level, which alleviates these symptoms. Withdrawal signs usually start within a few hours after the last cigarette and can last for several weeks.
Cigarettes are not only detrimental to the smoker, but also to non-smokers who breathe in the smoke. Take certain precautions in order to protect yourself and your family from the harmful effects of secondhand smoke.
