Smokers who think they are escaping the lung-damaging effects of inhaled tobacco smoke may have to think again, according to the findings of two major new studies, one of which the author originally titled “Myth of the Healthy Smoker.”

Chronic obstructive pulmonary disease, or C.O.P.D., may be among the best known dangers of smoking, and current and former smokers can be checked for that with a test called spirometry that measures how much air they can inhale and how much and how quickly they can exhale. Unfortunately, this simple test is often skipped during routine medical checkups of people with a history of smoking.

But more important, even when spirometry is done, the new studies prove that the test often fails to detect serious lung abnormalities that cause chronic cough and sputum production and compromise a person’s breathing, energy level, risk of serious infections and quality of life.

“Current or former smokers without airflow obstruction may assume that they are disease-free,” but that’s not necessarily the case, one of the research teams pointed out. These researchers projected that there are 35 million current or former smokers older than 55 in the United States with unrecognized smoking-caused lung disease or impairments. Many, if not most, of these people could get worse with time, even if they have quit smoking.

They are also unlikely to be referred for pulmonary rehabilitation, a treatment that can head off encroaching disability.

Perhaps most important, those currently smoking may be inclined to think they’ve dodged the bullet and so can continue to smoke with impunity. Doctors, who are often reluctant to urge patients with symptoms to quit smoking, may be even less likely to recommend smoking cessation to those with normal spirometry results.

What an inspirational article you have shared here. It is well said that smoking is particularly bad for your oral heal. Tobacco causes bad breath, cancer, loss of smell and taste, a hairy black tongue and mouth sores and spots. If you quit today, you’re one step closer to a healthy mouth. Either way, regularly visit your dentist for professional cleaning and advice on how to best take care of your teeth.

Thank you.
