How cigarette smoke causes cancer

That title might need a question mark following it, as I’m not absolutely convinced that this is definitive, but recent research appears to point to hydrogen peroxide as the source of cancer from cigarette smoke.

In the research study, Goldkorn and colleagues describe how they exposed different sets of human lung airway cells (in the laboratory) to cigarette smoke and hydrogen peroxide. After exposure, these cells were then incubated for one to two days. Then they, along with unexposed airway cells, were assessed for signs of cancer development. The cells exposed to cigarettes smoke and the cells exposed to hydrogen peroxide showed the same molecular signatures of cancer development, while the unexposed cells did not.

I wonder what implications this has for folks who use that same stuff to bleach their hair? How much trouble does the evaporating liquid cause to those exposed to it briefly and infrequently?

And a bonus quote for those that believe in the Bill of Rights:

“Guns kill, bombs kill and cigarettes kill,” said Gerald Weissmann, MD, Editor-in-Chief of The FASEB Journal. “While biologists can’t do much about the first two, studies like this will help in the fight against tobacco-related death and disease.

Sounds like a gun-control advocate to me, no? (via QJ Science)
