It is revealed in a recent study that more than half of active smokers or those who have recently quit smoking and thing they are disease free after passing successfully the lungs infection tests conducted on them might have entered the early stage of COPD or chronic obstructive pulmonary disease. 

The term COPD entails for a collection of chronic and acute lungs diseases, such as chronic bronchitis and emphysema. Breathlessness, persistent cough with phlegm, and recurrent chest infections are the most common symptoms of this category of disease. 

Smoking is identified as the primary cause of COPD. As per the recently released NHS figures almost three million people in the United Kingdom are affected with the diseases, and only 900,000 cases have been diagnosed till date. 

According to reports, researchers hailing from National Jewish Health are gearing to evaluate the relationship between COPD diagnosis and smoking. The research is conducted to debunk the myth of healthy smokers. 

The team has already recruited 8,872 people between 45 and 80 years of age who have reportedly smoked at least 10 cigarettes per day over a span of ten years for the purpose of the study. However, sources revealed that most of the participants in the evaluation smokes 30 to 50 cigarettes per day. 

Results obtained from the lung-function tests revealed that half of the participants in the evaluation were disease free.

During the evaluation several factors such as physical function, respiratory medication, CT scans, and respiratory symptoms of the participants were taken into consideration. Based on these aspects it was observed that as many as 55% of the participants who were disease free actually had some kind of impairment related to their respiratory symptom. 

These people also had a comparatively worse life quality than the nonsmokers. 

Smokers who achieved ‘normal’ results from the lung-function tests most often have a respiratory disease. A majority of these smokers are likely to be in the early stage of chronic obstructive pulmonary disease, said Elizabeth Regan, who is leading the team of researchers for the study.
