Smokeless tobacco and carcinogens

The effects of processing on a key group of carcinogens in several smokeless tobacco products from around the world: Tobacco-specific nitrosamines (TSNAs) in ng/g

Tobacco leaves, when processed differently, can create products with vastly different carcinogen levels. The levels of TSNAs (a major group of carcinogens) vary dramatically as a consequence of manufacturing processes that increase microbial production of nitrite, which reacts to form TSNAs.
