    TSNAs in Cigarette Smoke

    Some of the TSNAs found in cigarette smoke particles are

    N-nitrosonornicotine (NNN)
    4-(N-methyl-N-nitrosamino)-1-(3-pyridyl)-1-butanone (NNK)
    N-nitrosoanatabine (NAB)

    Other TSNAs include

    4-(N-methyl-N-nitrosamino)-1-(3-pyridyl)-1-butanol (NNAL)
    N-nitrosoanatabine (NAT)
    N-nitrosoanabasine (NAB)
    4-(N-methyl-N-nitrosamino)-4-(3-pyridyl)-1-butanol (iso-NNAL)
    4-(N-methyl-N-nitrosamino)-4-(3-pyridyl)butyric acid (iso-NNAC)

    The U.S. National Academy of Science estimates that a pack-a-day smoker is exposed to about 17 micrograms (mg) of cancer-causing TSNAs daily.

    Re: TSNAs in Cigarette Smoke

    Tobacco-specific N-nitrosamines (TSNAs) are known to be some of the most potent carcinogens present in smokeless tobacco, snuff and tobacco smoke.

    TSNAs consist of four chemical compounds:

    N-nitrosonornicotine (NNN)
    4-methyl-N-nitrosamino-1-(3-pyridyl)-1-butanone (NNK)
    N-nitrosoanatabine (NAT)
    N-nitrosoanabasine (NAB)

    Two of these chemical compounds, NNN and NNK, have been classifed as Group 2B carcinogens.
