Q & A
What is the leading cause of cancer-related death globally?
-Lung cancer is the leading cause of cancer-related death in the world.
How does smoking contribute to the spread of toxic substances in the body?
-Every time you smoke a cigarette, toxic gases pass into your lungs and then into your bloodstream, where they spread to every organ in your body.
What harmful substances are released when tobacco and its compounds burn?
-Burning tobacco and its compounds release thousands of dangerous chemicals, including over 40 known to cause cancer.
What are the poisonous gases found in cigarette smoke?
-Cigarette smoke contains the poisonous gases carbon monoxide and nitrogen oxide, as well as trace amounts of cancer-causing radioactive particles.
Is nicotine addictive, and how does it affect the brain?
-Yes, nicotine is an addictive chemical in tobacco. After inhalation, it flows through the bloodstream to the brain, inducing a pleasurable feeling and causing desensitization, which leads to cravings for more nicotine to feel normal.
What are some major health problems associated with smoking?
-Smoking increases the risk of heart disease, heart attack, stroke, lung cancer, and death from chronic obstructive pulmonary disease (COPD).
How does smoking lead to cardiovascular disease?
-Smoking causes the release of epinephrine, which raises blood pressure, and can damage the inner walls of arteries. This can lead to the buildup of fatty deposits called plaque, resulting in atherosclerosis and increased risk for heart attack.
What are the two main parts of the lungs damaged by smoking?
-Smoking damages the bronchial tubes (airways) and alveoli (small air sacs) in the lungs.
What is the condition known as smoker's cough?
-Smoker's cough is a condition where the body attempts to expel pollutants and mucus from the lungs by coughing repeatedly, often occurring after waking up.
What is COPD, and what are its implications?
-COPD, or chronic obstructive pulmonary disease, is a gradual loss of the ability to breathe caused by chronic bronchitis and emphysema. It is a progressive disease with no cure.
How can smoking during pregnancy affect the baby?
-If a woman smokes during pregnancy, it exposes the baby to harmful chemicals, increasing the risk of low birth weight, miscarriage, preterm delivery, stillbirth, infant death, and sudden infant death syndrome.
What are some other health effects of smoking besides respiratory and cardiovascular issues?
-Other health effects of smoking include low bone density, increased risk for hip fracture, gum disease, immune system dysfunction, delayed wound healing, and sexual impotence in men.
Outlines
๐ญ The Dangers of Smoking and Lung Cancer
This paragraph discusses the severe health risks associated with smoking, emphasizing lung cancer as the leading cause of cancer-related deaths globally. It explains how smoking introduces toxic gases and chemicals into the body, including over 40 known carcinogens. The addictive nature of nicotine is highlighted, along with the increased risks of heart disease, stroke, and chronic obstructive pulmonary disease (COPD). The paragraph also covers the damaging effects of smoking on the cardiovascular system, leading to conditions like atherosclerosis and heart attack, and the potential for blood clots and peripheral vascular disease. Lastly, it touches on the damage to the lungs' airways and alveoli, resulting in conditions like chronic bronchitis and emphysema.
๐คง The Consequences of Smoking on Health and Pregnancy
The second paragraph delves into the continuation of smoking's harmful effects, focusing on the recovery of the lungs during sleep and the body's attempts to expel pollutants through coughing, leading to smoker's cough. It discusses the development of chronic bronchitis and the damage to alveoli, which impairs oxygen and carbon dioxide exchange. The paragraph also addresses the carcinogenic substances in cigarette smoke and their role in causing various types of cancer. The risks of smoking to reproductive health, pregnancy outcomes, and infant well-being are detailed, including infertility, low birth weight, miscarriage, and sudden infant death syndrome. Additional health effects such as low bone density, gum disease, immune system dysfunction, and sexual impotence are also mentioned.
