Smokeless tobacco
Summary
Chewing tobacco, snuff, and similar products are associated with mouth, esophageal, and pancreatic cancer.
Detail
Smokeless tobacco is Group 1 with sufficient evidence for cancers of the oral cavity, esophagus and pancreas. WHO, IARC and major national cancer bodies agree that no form of tobacco is safe; smokeless products do not eliminate cancer risk.
