What Are 5 Harmful Effects Of Tobacco?

 Tobacco use and other people's smoke inhalation (passive smoking) causes about 5,000 deaths each year from cancer, stroke and heart disease.5 It is the leading cause of death and preventable disease in New Zealand.6, 7 Stop smoking completely, not just cut back. Smoking causes cancer, heart disease, stroke, lung disease, diabetes, and chronic obstructive pulmonary disease (COPD), which includes emphysema and chronic bronchitis. Smoking has also been linked to other cancers, leukemia, cataracts, type 2 diabetes, and pneumonia. Smoking causes cancer of the lung, esophagus, larynx, mouth, throat, kidney, bladder, liver, pancreas, stomach, cervix, colon and rectum, and acute myeloid leukemia (1-3). 

Smoking cigars can also lead to lung and throat cancers, with a lower increased risk than smoking. Although smoking is associated with a greater increased risk of cancer than smoking cigars, people who smoke cigars are still at greater risk for many health problems, including cancer, than non-smokers. In addition to known cancer risks, smoking can cause many other chronic (long-term) health problems that require ongoing treatment. 

In addition, exposure to secondhand smoke or environmental smoke is associated with an increased risk of cancer and heart disease, as well as other detrimental health effects. Studies show that the risk of developing cardiovascular disease is about 25-30% higher among people exposed to environmental tobacco smoke at home or at work. Higher risk of other serious diseases caused by tobacco use, such as heart and lung disease or recurrent cancer. 

In both sexes, smoking 1-4 cigarettes per day was associated with a significantly higher risk of death from coronary heart disease and death from all causes (both sexes), and in women - from lung cancer. Since the 1960s, the risk of developing lung cancer or COPD has actually increased in smokers compared to nonsmokers, although the number of cigarettes smoked per smoker has decreased (1). 

Smoking and the Heart Most people know that cigarette and tobacco smoking increases the risk of lung cancer and breathing problems, but few realize that it also significantly increases the risk of heart disease, peripheral vascular disease (diseases in the lungs), and blood vessels. arms and legs) and an aneurysm of the abdominal aorta. Smoking also increases the risk of tuberculosis, certain eye diseases, and immune system problems, including rheumatoid arthritis. 

Exposure to secondhand smoke increases the risk, up to 30 percent, that others may have lung cancer and many other cancers, which can lead to emphysema and heart damage. Smoking makes the blood sticky, raises the "bad" LDL cholesterol, and damages the lining of blood vessels. According to the American Heart Association, about 40,000 people die from heart and blood vessel disease caused by secondhand smoke. Exposure to secondhand smoke can cause health problems in both adults and children, such as coughing, phlegm, decreased lung function, pneumonia, and bronchitis. Smoking or any use of tobacco affects all major organs, the respiratory system, circulatory system, reproductive system, pulmonary system, sensory organs and increases the risk of many different types of cancer.
