It’s a no-brainer that smoking is bad for the health, yet a lot of people still continue to have their daily dose of nicotine. When you start, it’s almost impossible to stop, and that’s why it’s also one of the major causes of chronic diseases such as lung and heart disease, as well as certain types of cancer.
According to the World Health Organization (WHO), tobacco kills about six million people every year – about 600,000 of those are the result of secondhand smoke. This just shows that even the non smokers are affected once they are exposed to smoking.
But what really happens in the lungs when exposed to cigarette smoke? Smokers’ lungs explained by UK scientists in this report by James Gallagher on BBC News:
Rare ‘healthy’ smokers’ lungs explained
The mystery of why some people appear to have healthy lungs despite a lifetime of smoking has been explained by UK scientists.
The analysis of more than 50,000 people showed favourable mutations in people’s DNA enhanced lung function and masked the deadly impact of smoking.
The Medical Research Council scientists say the findings could lead to new drugs to improve lung function. Read more…
Smokers’ lungs explained: it’s all in the genes. As said in the report, the genes “affect the way the lungs grow and respond to injury.” But whether you have a good or bad gene, the key to a healthier and longer life is to avoid cigarette smoking in general.
WHO reports that most tobacco users want to quit but cannot since they are already addicted. It may be hard to stop, but there are counselling and medication available that help smokers succeed in quitting. Even some countries implement high tobacco taxes to hopefully reduce its use.
