When smoking mainstream cigarettes, a large amount of air passes through the filter of the smoke and enters the burning trembling cigarette butt, and there is no lack of oxygen at this time.

Therefore, the nitric oxide content in mainstream tobacco is low, and when it is not completely burned, the benzopyrene and other carcinogens formed are relatively small, so the harm of mainstream tobacco is relatively low. However, when these harmful substances are spit out, a large number of pollutants can be formed;

2. Side-flow smoke: refers to when you don't smoke, you take the cigarette and burn it, and the smoke that comes out is the side-stream smoke. Side-stream smoke does not have a large amount of air passing through the burning butt, and there is more anaerobic combustion at this time.
