BP and NNK can induce benzo(a)pyrene diol epoxide-dG and O6-methyl-dG adducts in human lung and bladder epithelial cells, but these inductions can be inhibited by acrolein, which also reduces DNA repair activity and repair proteins.
It is seen that electronic cigarettes have a higher amount of NNN when compared with nicotine replacement products such as nicotine band and nicotine gum in terms of TSNAs, and NNK is higher in nicotine band than in e-cigarette.
NNN, NNK, NAT, and NAB contents were determined according to SPE-LC-MS/MS methods [45-47].
NNK and NNK-Ae were purchased from Toronto Research Chemicals (Toronto, ON, Canada).
The main stream smoke of a cigarette contains 310mg of NNN and 150ng of NNK. These agents act locally on keratinocytes, stem cells and are absorbed and act in many other tissues in the body.

(44) Analyses of e-cigarette vapor yielded reductions in nicotine, carbon monoxide, tobacco specific nitrosamines (TSN) including N'-nitrosonornicotine (NNN), N'nitrosoanatabine (NAT), N'nitrosanabasine (NAB), and 4-(methylnitrosamino-1-(3-pyridyl)1-butanone (NNK), carbonyl compounds including formaldehyde, acetaldehyde, acrolein, and o-methylbenzaldehyde, volatile organic compounds such as toluene and pim-xyline, the metals cadmium, nickel, and lead, and polyaromatic hydrocarbons.
With respect to the NSRL hazard quotients for cancer related health effects, four of the nine chemicals analyzed exceeded 1.0 for the direct exposure to users; lead (1.33), formaldehyde (1.64), NNK (2.36), and cadmium (5.13).
