Tobacco is a major health risk and its use can have significant health effects. The three main health risks of tobacco are secondhand smoke, respiratory diseases, and lung infections. Secondhand smoke is the smoke emitted from burning tobacco products or breathing in the smoke exhaled by smokers. This form of exposure to tobacco has been linked to an increased risk of respiratory infections, lung diseases, and other respiratory symptoms. Furthermore, smoking hand-rolled cigarettes has been linked to stunted lung growth in children and adolescents as well as other significant health effects. Lastly, breathing in any type of tobacco smoke can increase one’s risk for developing various types of respiratory diseases such as asthma or bronchitis due to the presence of certain toxins found in cigarette smoke.


One of the most serious health risks from tobacco use is obstructive pulmonary disease (COPD), a serious lung condition primarily caused by smoking cigarettes or cigars. COPD can cause permanent damage to the lungs, making breathing difficult for those affected. Other health risks include heart diseases, lung and other cancers of the larynx, pharynx, esophagus and even other organs in the body.


In the last 50 years, smoking has been linked to ischaemic heart disease, cardiovascular diseases and some womens' diseases. It is estimated that today's smokers who smoke 4 cigarettes per day are at higher risk of disease than those who smoke fewer cigarettes. There is also evidence that lung cancer is more common in both sexes. The health risks associated with smoking tobacco have increased significantly over the last 50 years and it can be seen in the number of deaths due to tobacco related illnesses each year.


Smoking tobacco is linked to a variety of serious illnesses, including coronary heart disease, which is the leading cause of death worldwide. Coronary heart disease affects the cardiovascular system, which includes the heart and blood vessels. It occurs when arteries in the heart become narrowed or blocked due to plaque buildup from smoking tobacco. Heart attacks are also associated with smoking tobacco, as it damages the blood vessels and can reduce oxygen supply to vital organs in the body. According to a report from Centers for Disease Control (CDC), 52 percent of all cardiovascular diseases are caused by smoking cigarettes alone. This means that one cigarette can increase your risk of having a stroke or heart attack drastically over time. The CDC also reports that 40 percent of all deaths due to coronary heart disease were caused by smoking cigarettes, making it one of the most dangerous health risks associated with smoking tobacco products today.


Studies have also found that smoking can cause a variety of long-term complications, including cancer risks, cardiovascular health problems and damage to other body systems. In addition, smoking can cause a variety of short-term effects on the body, such as increased risk of stroke and heart attack. The American Cancer Society estimates that approximately 30 percent of all cancer deaths in the US are directly related to smoking cigarettes and other tobacco products.


There are three main health risks associated with tobacco use: smoke damage, obstructive pulmonary disease, and lung diseases. Smoke damage is caused by the inhalation of cigarette smoke or secondhand hand smoke. This toxic mix of more than 7,000 chemicals can cause a range of respiratory problems and long-term lung damage. Obstructive pulmonary disease is a chronic condition where air flow to the lungs becomes blocked, making it difficult to breathe normally. Lung diseases such as emphysema and chronic bronchitis are common among states smokers due to direct tobacco use. Many other illnesses have been linked to long-term exposure to cigarette smoke including heart disease, stroke, and various types of cancer. The health risks associated with smoking cigarettes are both immediate and long term; the effects vary from person to person but can be severe for those who are exposed over an extended period of time.
