Tobacco products are items made from the leaves of the tobacco plant, which contain nicotine, a highly addictive substance. Common forms of tobacco products include cigarettes, cigars, and pipe tobacco. These products are often smoked, but they can also be chewed or sniffed. In addition to traditional smoking products, there are also smokeless tobacco options, such as chewing tobacco and snuff. Many people use tobacco products for various reasons, including socializing or stress relief, but they are associated with serious health risks, including lung cancer, heart disease, and respiratory issues.
