Coughing and Other Respiratory Symptoms Improve Within Weeks of Smoking Cessation

If the proven long-term benefits of smoking cessation are not enough to motivate young adults to stop smoking, a new study shows that 18- to 24-year olds who stop smoking for at least two weeks report substantially fewer respiratory symptoms, especially coughing. The study findings are detailed in Pediatric Allergy, Immunology, and Pulmonology, a peer-reviewed journal published by Mary Ann Liebert, Inc. The article is available online.

Karen Calabro, DrPH and Alexander Prokhorov, MD, PhD, The University of Texas MD Anderson Cancer Center, Houston, compared self-reported respiratory symptoms among two groups of college students who participated in programs designed to motivate them to stop smoking. One group achieved smoking cessation for two weeks or longer and the other group failed to stop smoking. More than half of the students smoked 5-10 cigarettes a day and had smoked for 1-5 years.

“That the benefit of stopping smoking starts in days to weeks–not years or decades–is important. Now health care providers can counsel young smokers that their breathing can feel better soon after they stop. This can help to motivate young adults to stop smoking before the severe damage is done,” says Harold Farber, MD, MSPH, Editor of Pediatric Allergy, Immunology, and Pulmonology and Associate Professor of Pediatrics, Section of Pulmonology, Baylor College of Medicine, Houston, TX.

Pediatric Allergy, Immunology, and Pulmonology is a quarterly peer-reviewed journal published in print and online. The Journal synthesizes the pulmonary, allergy, and immunology communities in the advancement of the respiratory health of children. The Journal provides comprehensive coverage to further the understanding and optimize the treatment of some of the most common and costly chronic illnesses in children. It includes original translational, clinical and epidemiologic research; public health, quality improvement, and case control studies; patient education research; and the latest research and standards of care for functional and genetic immune deficiencies and interstitial lung diseases.

When we smoke and for all the years that we smoked each and every puff on a cigarette destroyed the cilia, or tiny little hair-like projections lining our respiratory tract. These cilia are responsible for filtering out all the impurities we breathe on a daily basis. They line our nose and reach all the way down into our lungs. When we quit smoking, the first thing, essentially to start repairing itself, is the respiratory tract......and as soon as we take the last puff, the cilia start to regenerate themselves. In some people these cilia grow back faster than others.

Coughing is a natural byproduct of the reemerging cilia. It makes no difference how long or how much you smoked, the rate of regrowth can and is different in most of us. The faster the cilia grow, the more likely we are to cough lots in the first weeks of a quit. Our bodies are healing and our lungs are clearing themselves of all the toxins and impurities.
