Smoking stays in your genes after you quit

Cigarette habit may leave a molecular mark.

Gene expression changes brought on by heavy smoking may persist long after the smoker has kicked the habit, researchers have found. The results could provide a molecular explanation for the continued increased risk of lung cancer and other pulmonary ailments among former smokers.

Interesting piece of research. The question is whether other kinds of damaging environmental effects would also cause long-term genetic changes in individuals.

Does this research conclude the same results with second hand smoke?

I am a smoker.and so surprised abot the results this paper showed. but Iam also confused abot the samples you had used. in briefle, they are different individuls. maybe the differet expression is normal.

Since lung cancer is not the be-all and end-all of evils that most people talk about, I would hesitate to make too much of the study. It is important to quit for many reasons, not just the possibility of lung cancer. Nobody every said that quitting would restore you to pristine status. What is more important is the removal of the habit from society, so that young generations cease to start, and the improvement of training to encourage quitting. I still see the same old commercial philosophy encouraging the use of nicotine patches and other such nonsense solutions that only serve to perpetuate the acid-alkali imbalance which is at the root of the craving.
