Tobacco smoking refers to the practice of ingesting the smoke that is produced from burning tobacco in cigarettes, cigars and pipes. Smoking is one of the most common forms of consuming tobacco. Nicotine released from tobacco smoking in the body contains lead and other harmful chemicals.
Tobacco smoking kills millions of people worldwide and is one of the leading causes of lung cancer along with tuberculosis, arthritis and eye disease. What is even more shocking that a percentage of these deaths are due to “passive smoking” i.e. of non-smokers who are forcefully exposed to the cigarette smoke exhaled by smokers. Consumption of all forms of tobacco is harmful and there is no “safe level” of tobacco exposure.
Chewing tobacco is a smokeless tobacco product that is usually placed between the lower gum and cheek to extract its flavour. After the tobacco mixed saliva reaches a quantity in the mouth, the user spits it out and waits for the next round of saliva to form. Almost all chewing tobacco products are created through fermentation and leaf curing,
While the levels of chemicals are lower in chewed tobacco as compared to smoked tobacco, they are equally harmful. Those who chew tobacco are exposed to almost 25 chemicals that can cause cancer and death. Tobacco-specific Nitrosamines, or TNSA, are the most harmful cancer-causing substances in smokeless tobacco.
