Effects of tobacco
The health effects of tobacco are the consequences that use of tobacco has on human health, and worry about health effects of tobacco has a long history. Study has concentrated principally on cigarette tobacco smoking. Research shows a close link between lung cancer and smoking.
A few years later the British Doctors Study, a study of some forty doctors over twenty years, established the proposal, formed on which the government issued advice that lung cancer and smoking rates were linked.
The single greatest cause of preventable death globally is tobacco use. As many as half of individuals who use tobacco die from the outcome of this use.
WHO evaluates that each year tobacco causes about six million deaths,-about ten percent of all deaths with six lac of these arising in non-smokers due to second hand smoke.
In the twentieth century tobacco is believed to have caused hundred million deaths. Likewise, the U.S Centers for Disease Control and Prevention reports tobacco use as "the single most crucial preventable risk to human health in developed countries and an significant cause of premature death around the world."
Tobacco use leads most frequently to diseases affecting the liver, lungs and heart. Smoking is a main risk factor for strokes, heart attack, cancer (particularly lung cancer, cancers of the larynx and mouth, and pancreatic cancer). It also causes peripheral vascular disease and hypertension and chronic obstructive pulmonary disease (COPD) (including emphysema and chronic bronchitis).
