Study Finds that Smoking Damages DNA Within Minutes

Smoking has negatively impacted my family for years now so when I came across this article I felt compelled to post it. I had always known that smoking caused lung cancer but I had no idea just how fast it started…

Cigarettes damage the body within minutes of taking a puff, new research suggests. In a small study, scientists tracked the level of a chemical associated with cancer—one polycyclic aromatic hydrocarbon (PAH)—in 12 smokers and found it began damaging their DNA within 15 to 30 minutes of finishing a cigarette, according to a report published in the American Chemical Society’s journal Chemical Research in Toxicology. “Almost everybody knows that smoking can cause lung cancer,” Martin Dockrell, director of policy and research at the advocacy group Action on Smoking and Health, told BBC News. “The chilling thing about this research is that it shows just how early the very first stages of the process begin—not in 30 years, but within 30 minutes of a single cigarette. But it is never too late to quit.

I hope this was informative and will sway more people to quit smoking.
