Question

Quizplus · Accepted Answer

N-nitrosamine is a highly carcinogenic substance found in tobacco smoke. It is formed when nicotine in tobacco is burned at high temperatures. Sidestream smoke, which is the smoke that comes from the burning end of a cigarette, contains a higher concentration of N-nitrosamine than mainstream smoke, which is the smoke that is exhaled by the smoker. This is because the temperature of the burning tobacco in the sidestream smoke is higher than the temperature of the tobacco in the mainstream smoke, which leads to the formation of more N-nitrosamine.
