Prolonged inhalation of benzene leaves smokers at a high risk of contracting acute myeloid leukemia and is also believed to contribute to chronic lymphocytic leukemia. The damage to white blood cells over a long period of is quite substantial.

Tobacco-specific nitrosamines – These are a group of carcinogenic chemicals that are found to exist in tobacco and tobacco smoke, namely the Nicotine-derived nitrosamine ketone (NNK) and N-Nitrosonornicotine(NNN). According to studies, these two are hugely responsible for oral cancer. NNK is lung specific meaning it’s more likely to be found in the human lungs, thus it can’t be eliminated as a possible cause for lung cancer.
