If asthma patients quit smoking habit, the lung functions may improve within two months. The researchers found during a study that, after just seven days of without cigarettes, the lung functions in asthma patients improved by fifteen percent.
Dr. Neil C. Thomson, of the departments of respiratory medicine and immunology at the University of Glasgow said that the improvement in lung function displays about a reversible component to the harmful effects of smoking in asthma.
He says further that this improvement might be happened either because of the removal of the acute bronchoconstrictor effects of cigarette smoke or a reduction in the proinflammatory effects of cigarette smoke. The July issue of the American Journal of Respiratory and Critical Care Medicine has published the report.
