Cigarettes are intentionally planned to provide a quick nicotine hit. Nicotine induces addiction in a similar manner as cocaine or heroin. Nicotine raises the heart rate and causes effects on many different components of the body and brain. There are many reasons as to why people smoke. People utilize smoking to support them if things are not right. Others smoke together with other people as a shared task or as a way to initiate conversations and increase self confidence. There is also a belief that smoking aids in reducing weight.
There are a number of diseases that are associated with smoking including lung cancer, emphysema, bronchitis, coronary heart disease, among others. Lung cancer is not only the disease that is mostly linked to smoking but is also the risk factor that is most responsible for the disease (Burdon, Juniper and Killian).
Emphysema, which is a chronic, terminal disease, is primarily caused by cigarette smoking. Function of the lung, as well as patterns of breathing, are critically modified by this health trouble that increasingly restricts levels of oxygen in the bloodstream. Based on the American Lung Association, this disease and its associated disease, chronic bronchitis, stands for the fourth main source of all deaths in America. This disease can be contributed by contact with the environmental contamination as well as occupational particulate, though about 85 percent of every case of emphysema is linked to use of tobacco (Elisabetta and Giorgio).
The typical smoker's cough associated with chronic bronchitis renders this respiratory illness almost synonymous with cigarette smoking. Bronchitis may be brought about by other environmental irritants, though it frequently affects users of tobacco.The chronic bronchitis is listed as the illness that most frequently linked to smoking being 49 percent of all smokers by the Centers for Disease Control.
Smoking increases the danger for coronary heart disease as well as heart attack by between two and four times the normal rate in nonsmokers. Tobacco smoking speeds up vascular decline through atherosclerosis, or thinning of the arteries. This decrease in circulation may as well upset flow of oxygen to the heart, leading to heart attack as well as heart failure. Contact with secondhand smoke raises a risk of nonsmokers for heart disease by 30 percent (David and Daniel).
