Which statement is true regarding smokeless tobacco?

The statement that smokeless tobacco can lead to cancer is true and supported by extensive scientific research. Smokeless tobacco, which includes products like chewing tobacco and snuff, contains numerous harmful chemicals and carcinogens that can increase the risk of various types of cancer, particularly cancers of the mouth, throat, esophagus, and pancreas. The risk associated with smokeless tobacco use is significant, as it can cause not only cancer but also other serious health issues, including gum disease and tooth decay.

In contrast, the other statements inaccurately represent the health implications of smokeless tobacco. It is not a safe alternative to smoking; in fact, both forms of tobacco use pose serious health risks. While smokeless tobacco may not involve inhaling smoke, it is still highly addictive and can lead to dependence due to the presence of nicotine. Additionally, smokeless tobacco products contain a variety of harmful substances, making the claim that they contain no addictive substances false. Finally, smokeless tobacco is not a healthier choice compared to traditional cigarettes, as both can have detrimental effects on health.
