Tobacco is partially or completely made up of tobacco leaves that are used as raw material. Tobacco products can be consumed in the form of chewing, sucked and in snuffing form. Snuffed and chewing tobacco is also known as smokeless tobacco. Generally, tobacco is responsible for containing all the highly addictive psychoactive elements such as nicotine. According to a different literature review, it is stated that tobacco use is considered as one of the major risk factors for the cause of chronic disorders e.g. cancer, lung cancer and even consumption of it leads toward the cardiovascular diseases. Despite the severe consequence of tobacco use, it is still common all over the world. Although a large number of countries has restricted legislations for it control like restriction for its advertisement and regulating authorities are there to control buy and sale of tobacco and its products as well (“Tobacco”).

Tobacco use is thought to be one of the major leading causes of cancer and even death from cancer. Basically, people who consume tobacco or tobacco related products on the regular base and people who sit in a smoking environment are more vulnerable to cancer. Cancer risk increased when tobacco is consumed because tobacco contains many chemicals that are responsible for DNA damage (“Tobacco”). Smoking not only harmful only to any specific body organ it basically affects the overall body and in other words, it diminishes the overall health of a person. Tobacco use is accountable for causing various types of cancer that are included as lung cancer esophagus, mouth, bladder, kidney, pancreas, cervix, colon, rectum liver, throat and stomach etc. People who mostly consumed chewing or snuffing tobacco has more risk of mouth esophagus and pancreatic cancer (“Smoking And Cancer | Overviews Of Diseases/Conditions | Tips From Former Smokers | CDC”).

Tobacco use in any form is not safe. People who used any kind/brand of tobacco are advised to quit it. People who take advice serious despite of their age their lifestyle improved like their life expectancy rate increased as compared to those who do not quit smoking. However, quitting smoking after cancer diagnostic stage the risk of death due smoking are decreases. Quitting smoking after cancer diagnosis almost 30-40% risk of death rate reduced.Tobacco smoke generally contains a various form of chemical which are thought to be dangerous for smoker and nonsmoker as well. Tobacco is harmful even when it is breathed in little amount (“Study Confirms There Is No Safe Level Of Smoking”).

According to assorted reviews, it is stated that almost tobacco contains 7,000 chemicals. Out of these 250 are considered as injurious to health. Some of these are known as hydrogen cyanide, ammonia and carbon dioxide. Amongst the 250 chemicals of tobacco that are known as detrimental, at least 69 out of them are held to be responsible for cancer cause. These cancer-causing chemicals include aromatic amines, acetaldehyde, arsenic, benzene, cadmium, Ethylene oxides, Tobacco-specific nitrosamines, vinyl chloride and polycyclic aromatic hydrocarbons (PAHs) (“Harms Of Cigarette Smoking And Health Benefits Of Quitting”).

Tobacco is injurious to health because it contains a high level of chemicals in it, e.g. cigarette contains chemical when people smoke a cigarette these chemicals enter into the bloodstream and then these chemicals affect the whole body. That is why smoking causes many serious diseases, includes 14 types of cancer as well as heart disease and different sort of lung disorders. Almost out of 5 smokers 4 are suffering from lung cancer. Lung cancer is one of the most common forms of all cancers and it is also thought to be a widespread source of cancer death (“How Smoking Causes Cancer”).

In relation to smoke and cancer, it is stated that almost more than 16 million people have been suffering from common disease due to smoking habit; and more than 20 million American died just because of smoking, including 2.5 million has died only owing to exposure to cast-off smoke. However, 8.6 million people are having an illness because of smoking. Smokers have 30-40% more chances of becoming diabetic patient than the no smokers (tobacco).

Whereas 18 million males are having age more than 20 are suffering from erectile dysfunction. Smoking is the main cause of the erectile dysfunction (ED) because cigarette smoke alters the flow of blood that is needed for an erection. On the overall point of literature, almost smoker die 13-14 years before then such people who do not smoke or nonsmoker (“Facts About Smoking And Tobacco Use”).

Lung cancer is the major leading cause of death among men and women. Almost 90% men and 80% women deaths occur due to smoking. According to epidemiological studies, it is evident that lung cancer causes due to PAH and nitrosamines (Vineis et al. 99-106). polycyclic aromatic hydrocarbons (PAH) and nitrosamines are the major carcinogens in tobacco smoke Not only cigarette but also smoking any other forms of tobacco use such as bidi, cigar and pipe can also cause cancer in numerous body organs(tobacco).

Worldwide use of tobacco has been drastically increased and it is also like to be worse in future as well. In developed countries, approximately 30% death rate due to cancer whereas the rate of death in developing countries are also increasing due to tobacco smoking. The rapid rise in tobacco consumption resulted in the rapid rise of lung cancer after a period of latency. Furthermore, smoking accounts for more than 85% of all lung cancer deaths. Risk of disease owed to smoking can be controlled by preventing smoking behavior (“Tobacco: Which Is The True Cancer Risk?”). In short decreased smoking prevalence decreased the risk of lung cancer in various countries such as UK, Finland, and Australia; however present smoking pattern carry on then in 21st-century smoking will be accountable for more than 1 billion death.
