This reason Smokers Can Have Healthy Lungs

British scientists have found the explanation behind the mystery that few people seem to have healthy lungs although in their lifetime smoked.

Scientists are analyzing as many as 50,000 people. As reported by the BBC recently, following some reason smokers can have healthy lungs.

First, the scientists observed a chronic lung disease that causes breathing difficulties, coughing, and recurrent chest infections. This condition is estimated to occur in three million people in the UK, including diseases such as bronchitis and emphysema.

However, researchers have found parts of the DNA that reduces the risk of chronic lung disease stretcher. So, smokers who have good genes have a lower risk affected by chronic lung disease than in those who had had bad genes. Thus, if people smoked all his life, but have good genes, it can have healthy lungs.

Secondly, smoking can also increase the risk of heart disease and cancer, which are not covered in this study. However, the scientists found that parts of the genetic code is more visible in smokers than in non-smokers.

The genetic code is changing brain function and easier for people to become addicted to nicotine, although this remains to be proven. "Instructions were fantastic about the workings of the body that had never previously known, and things like this that may yield important breakthroughs in drug development." Said one of the researchers at the University of Leicester, Professor Martin Tobin.

Meanwhile, the head researcher British Lung Foundation, Ian Jarrold said the findings represent an important step in helping us get a clearer picture of the reality of lung health complex and fascinating. "Understanding the genetic predisposition is important to help us develop new treatments in people who suffer from lung diseases and also for healthy people, in order to make their lungs better," said Ian Jarrold.
