They evaluated a national sample of 32,320 US adults collected between 2013 and 2014, who provided urine samples for the analysis of nitrosamine-specific tobacco, N-nitrosonornicotine ( NNN), a known oral and esophageal carcinogen, and 4- (methynitrosamino) -1- (3) -pyridyl-1-butanol (NNAL), a carcinogenic lung metabolite (NNK), as well as n total among participants, 48% are women and 61% are non-Hispanic whites aged 18 to 90, with a median age of 35 years.

All categories of smoking showed high levels of nicotine and TSNA compared to non-users. Smokeless tobacco users have the highest level of exposure to TSNA, whether they use a tobacco product or other types of products.
