FDA Proposes to Limit NNN in Smokeless Tobacco


The potent carcinogen N-nitrosonornicotine (NNN) is a tobacco-specific compound found widely in smokeless tobacco products like snuff and chewing tobacco--causing significantly higher oral cancer risks for users. The proposed new rules will require that NNNs not exceed 1 microgram/g of tobacco (dry weight) and that packaging include a manufacturing code, expiration date, and storage instructions. There is a 75-day period for public comment after formal publication.

PositiveTip: Support these rule changes while recognizing the best way to avoid NNN exposure is to not use these tobacco products.
