Smokeless tobacco refers to tobacco products that are used without combustion, allowing users to consume nicotine without inhaling smoke. Common forms include chewing tobacco and snuff, which are placed in the mouth or nasal cavity. These products are often marketed as a less harmful alternative to smoking, but they still pose significant health risks. The use of smokeless tobacco can lead to various health issues, including gum disease, tooth decay, and an increased risk of oral cancer. Despite these dangers, many individuals continue to use these products, often due to addiction or cultural practices surrounding tobacco use.
