Smoke constituents

According to the U.S. Department of Health and Human Services^[1], the following carcinogens are found in cigarette smoke:

N-Nitrosodimethylamine: 5.7 to 43 nanograms
N-Nitrosodi-n-Propylamine: 1 nanogram
4-(N-Nitrosomethylamino)-1-(3-Pyridyl)-1-Butanone: up to 4.2 micrograms
N-Nitrosonornicotine: 14 micrograms
N-Nitrosopiperidine: unknown
