“Smoking is injurious to health.”

We all are aware of this sentence but this is not the whole story. It only depicts the one-sided story and is all about the person directly involved in smoking. But it is a fact that most of the smoke produced during smoking does not go to the lungs of a smoker. Rest of the smoke remains in the environment around and if someone is present there will be effected highly due to inhaling of this smoke.

“The second-hand smoke contains a combination of two clouds of smoke; one from the burning of a cigarette (mainstream smoke) and other from the exhalation of a smoker (sidestream smoke) and this is also known as passive smoke.”

It is a proven fact that second-hand smoke contains more than seven thousand chemicals in it and 70 of them can cause cancer.
