Smoking can cause lung disease by damaging your airways and the small air
sacs (alveoli) found in your lungs. According to World Health Organization,
the tobacco epdidemic is one of the biggest public health threat,the world
has ever faced, killing over 8million people per year. Including 1.2million
from second-hand exposure to smoking.Second-hand tobacco smoke is the smoke emitted from the burning end of a cigarette or from other smoked tobacco products (such as bidis and water-pipes) and the smoke exhaled by the smoker. More than 4000 chemicals have been identified in tobacco smoke and there is no safe level of exposure to second-hand tobacco smoke
Key Facts
Tobacco kills up to half of its users
Tobacco kills more than 8 million people each year. More than 7 million of those deaths are the result of direct tobacco use while around 1.2 million are the result of non-smokers being exposed to second-hand smoke
On average, people who smoke die about 10 years earlier than people who have never smoked
Most people know smoking can cause cancer. But it can also cause a number of other diseases and can damage nearly every organ in the body, including the lungs, heart, blood vessels, reproductive organs, mouth, skin, eyes, and bones.
Smoking damages the airways and small air sacs in your lungs. This damage starts soon after someone starts smoking, and lung function continues to worsen as long as the person smokes. Still, it may take years for the problem to become noticeable enough for lung disease to be diagnosed
