Naomi Hunter: Are you smoking?
Snake: Yeah, so what?
Naomi: Didn't you know that cigarettes contain benzopyrene, a chemical that leads to lung cancer? We now know that when benzopyrene enters the body, it changes to benzopyrene diolepoxide (BPDE) and attaches to the receptors on the P53 gene, the gene that causes lung cancer. The BPDE attaches to the P53 gene in three specific locations and causes precancerous changes to the lung tissue.
Snake: You know a lot about science, but you don't know how good a cigarette tastes in the morning.
