You probably know about the relationship between smoking and lung cancer, but did you know smoking is also linked to heart disease, strokeand other chronic diseases? Smoking can increase your risk for cancer of the bladder, throat, mouth, kidneys, cervix and pancreas. Thinking about quitting? Look at the facts!
Why should you quit?
- Smoking is the most preventable cause of death in the United States.
- Almost one third of deaths from coronary heart disease are due to smoking and secondhand smoke.
- Smoking is linked to about 90% of lung cancer cases in the United States.
- Smoking rates overall are down, but too many adults still smoke, vape and use other forms of tobacco, especially between the ages of 21 and 34.
- About half of U.S. children ages 3-11 are exposed to secondhand smoke.
- On average, smokers die more than 10 years earlier than nonsmokers.
- You can be one of the millions of people who successfully quit every year.
What makes cigarettes so toxic and dangerous?
There are more than 5,000 chemical components found in cigarette smoke and hundreds of them are harmful to human health, according to the Centers for Disease Control and Prevention.
Here are a few examples:
- 1,3-Butadiene is a chemical used to manufacture rubber. It is considered to be a carcinogenic chemical that can cause certain blood cancers.
- Arsenic is used to preserve wood. Some arsenic compounds have been linked to cancer of the lung, skin, liver, and bladder.
- Benzene is used to manufacture other chemicals. It can cause cancer, particularly leukemia, in humans.
- Cadmium is a metal used to make batteries. Cadmium and cadmium compounds can cause lung cancer and have been associated with kidney and prostate cancer.
- Chromium VI is used to make alloy metals, paint and dyes. Chromium VI compounds cause lung cancer and have been associated with cancer of the nose and nasal sinuses.
- Formaldehyde is used to make other chemicals and resins. It is also used as a preservative. Formaldehyde causes leukemia and cancer in respiratory tissues.
- Polonium-210 is a radioactive element that has been shown to cause cancer in animals.
- Tar is not one single chemical, instead it describes several chemicals that are in tobacco smoke. It leaves a sticky, brown residue on your lungs, teeth and fingernails.
Carbon monoxide & nicotine: A dangerous duo
Carbon monoxide is a harmful gas you inhale when you smoke. Once in your lungs, it’s transferred to your bloodstream. Carbon monoxide decreases the amount of oxygen that is carried in the red blood cells. It also increases the amount of cholesterol that is deposited into the inner lining of the arteries which, over time, can cause the arteries to harden. This leads to heart disease, artery disease and possibly heart attack.
Nicotine is a dangerous and highly addictive chemical. It can cause an increase in blood pressure, heart rate, flow of blood to the heart and a narrowing of the arteries (vessels that carry blood). Nicotine may also contribute to the hardening of the arterial walls, which in turn, may lead to a heart attack. This chemical can stay in your body for six to eight hours depending on how often you smoke. Also, as with most addictive substances, there are some side effects of withdrawal. And some e-cigarettes and newer tobacco products deliver even more nicotine than traditional cigarettes.
Secondhand Smoke
Smokers aren’t the only ones affected by tobacco smoke. Secondhand smoke and vapor is a serious health hazard for nonsmokers, especially children. Nonsmokers who have high blood pressure or high blood cholesterol have an even greater risk of developing heart diseases when they’re exposed to secondhand smoke. Secondhand tobacco smoke contributes to thousands of premature heart disease and lung cancer deaths. Studies show that the risk of developing heart disease is about 25-30 percent higher among people exposed to environmental tobacco smoke at home or work. Secondhand smoke promotes illness, too. Children of smokers have many more respiratory infections than do children of nonsmokers.
The bottom line
Cigarettes, e-cigarettes and tobacco products contain many dangerous toxins. The best thing you can do for your health is to quit tobacco entirely. Don’t spend the rest of your life chained to a nicotine addiction. Thousands of people kick the habit every year, and you can be one of them. It may not be easy, but you can do it!
As a seasoned expert in public health and tobacco control, I bring a wealth of knowledge and hands-on experience to shed light on the critical link between smoking and its detrimental effects on human health. My expertise spans several dimensions, including the epidemiology of tobacco-related diseases, the chemical composition of cigarette smoke, and the broader societal impact of smoking.
The article you've presented touches upon key aspects of the pervasive health risks associated with smoking, emphasizing the urgent need for individuals to quit tobacco use. Let's break down the concepts mentioned and delve into the wealth of evidence supporting these claims:
-
Health Risks and Diseases:
- Smoking is not solely linked to lung cancer but is also associated with heart disease, stroke, and various chronic conditions. This is a well-established fact supported by numerous epidemiological studies conducted globally.
-
Cancer Risk:
- Smoking significantly increases the risk of cancers in various organs, including the bladder, throat, mouth, kidneys, cervix, and pancreas. The statistical correlation between smoking and these cancers has been extensively documented in scientific literature.
-
Mortality Rates:
- Smoking is identified as the most preventable cause of death in the United States. The claim that almost one-third of coronary heart disease deaths are attributable to smoking and secondhand smoke is substantiated by mortality data and epidemiological studies.
-
Lung Cancer and Smoking Rates:
- Approximately 90% of lung cancer cases in the United States are linked to smoking, underscoring the profound impact of tobacco use on respiratory health. The assertion that smoking rates have decreased overall but remain prevalent, especially among adults aged 21-34, aligns with trends observed in public health surveys.
-
Secondhand Smoke Exposure:
- The article rightly points out that about half of U.S. children aged 3-11 are exposed to secondhand smoke, emphasizing the broader impact of smoking on nonsmokers, especially vulnerable populations like children.
-
Life Expectancy:
- Smokers, on average, die more than 10 years earlier than nonsmokers. This is a stark statistic highlighting the direct correlation between smoking and reduced life expectancy.
-
Chemical Components in Cigarette Smoke:
- The hazardous nature of cigarette smoke is attributed to over 5,000 chemical components, with hundreds deemed harmful by the Centers for Disease Control and Prevention. The listed examples such as 1,3-Butadiene, Arsenic, Benzene, Cadmium, Chromium VI, Formaldehyde, Polonium-210, and Tar are indeed toxic and have established links to various health conditions, including cancer.
-
Carbon Monoxide and Nicotine:
- The elucidation of how carbon monoxide and nicotine contribute to heart disease and other cardiovascular conditions is rooted in physiological mechanisms. The impact on oxygen transport, cholesterol deposition, and arterial hardening is well-documented in scientific literature.
-
Secondhand Smoke Risks:
- The dangers of secondhand smoke are underscored, particularly for nonsmokers, with a focus on increased risks for heart disease and lung cancer. Studies supporting a 25-30% higher risk of heart disease among those exposed to environmental tobacco smoke at home or work align with the broader understanding of passive smoking risks.
-
Quitting Tobacco:
- The article encourages readers to quit tobacco entirely, highlighting the thousands of successful quitters each year. This advice is grounded in comprehensive smoking cessation programs and the documented health benefits of quitting.
In conclusion, the provided information underscores the urgent need for public awareness and individual action to combat the pervasive health hazards associated with smoking. The evidence presented aligns with the broader scientific consensus on the detrimental effects of tobacco use, making a compelling case for individuals to prioritize their health and quit smoking.
