According to a recent study by the US. National Institute for Occupational Safety and Health, U.S. workers are continuing, and slightly increasing, their use of smokeless tobacco products. Smokeless tobacco (snuff and chew tobacco) are known to cause oral, esophageal and pancreatic cancer. The study did not include other smokeless tobacco products, such as e-cigarettes and candy-flavored dissolvable tobacco, therefore the usage numbers may actually be underestimated.
