FDA Proposes Limit on Carcinogenic Chemical in Smokeless Tobacco

The Food and Drug Administration is proposing to establish a limit on N-nitrosonornicotine (NNN) in finished smokeless tobacco products, it said (here). The agency said NNN is a “potent carcinogenic agent found in smokeless tobacco products and is a major contributor to the elevated cancer risks associated with smokeless tobacco use.” FDA proposes that the limit would apply to smokeless tobacco products manufactured, imported, distributed or sold beginning three years after the publication date of the final rule. Comments on the proposal are due April 10.
