Even after an increase in the number of bans on smoking in airplanes, restaurants and many other public places, it seems that this has hardly been able to have any positive impact upon those who desire smoking every now and then.

And now, researchers have presented foremost biological data that offers confirmation to health hazards that are posed due to the exposure to second-hand smoke.

Dr. Ronald Crystal at Weill Cornell Medical College, who led the team of researchers, documented the alterations in genetic shifts amongst people, who did not smoke, was triggered by exposure to secondhand smoke of cigarette.

All the public health bans inflicted upon smoking are the byproducts of populace-based information that associates secondhand smoke exposure and an elevated instance of lung diseases like emphysema and also, lung cancer, however, it does not offer any genetic cause for the drawn parallelism.

It is for the first time, the now researchers can state one probable reason, which is, the passive receiver's genetic set that in actuality suffer the impact.

The results sought by the study suggested that the genetic mutations amongst those exposed less to cigarette smoke or secondhand smokers mirrored those of smokers, which represented the initial molecular move towards later development of lung disease.
