The Comprehensive Smokeless Tobacco Health Education Act of 1986 (Public Law 99-252) required three rotating warning labels on smokeless tobacco packaging and advertisements:
WARNING: This product may cause mouth cancer.
WARNING: This product may cause gum disease and tooth loss.
WARNING: This product is not a safe alternative to cigarettes.
Warning labels that appear on smokeless tobacco products in the United States are weaker, less informative, and less obvious labels used on the products than they are in some countries. The FTC is reviewing public comments on the effectiveness of the existing warning labels.
