Template:Warning/Nicotine
The nicotine metabolite N-nitrosonornicotine is classified as a IARC Group 1 carcinogen Nicotine in the mouth and stomach can react to form N-nitrosonornicotine (NNN),[1] a known type 1 carcinogen,[2] suggesting that consumption of non-tobacco forms of nicotine may still play a role in carcinogenesis.[3] This suggests that even oral nicotine replacement therapy products could theoretically contribute to cancer risk. To stay safer: Nicotine patches used as directed do not pose this risk, since NNN formation does not occur through absorption via the skin. |
