Nornicotine in Smokeless Tobacco as a Precursor for Carcinogen Exposure

Recruiting

Smokeless tobacco users who are unable or unwilling to quit tobacco use may be exposed to the potent oral and esophageal carcinogen NNN not only from tobacco itself, but also via its endogenous synthesis from nornicotine. The proposed study will lead to an understanding of the endogenous formation of NNN from nornicotine in humans, and will also investigate the effect of the reduction of nornicotine content in smokeless tobacco on the extent of endogenous NNN formation. The knowledge gained in this study will lead to the development of recommendations for the regulation, or potentially elimination, of nornicotine in smokeless tobacco products in order to minimize exposure to NNN in the users of these products.

I'm interested
