The Impact of Tobacco Smoking on Adult Asthma Outcomes
<b>Background</b>: Tobacco smoking is associated with more severe asthma symptoms, an accelerated decline in lung function, and reduced responses to corticosteroids. Our objective was to compare asthma outcomes in terms of disease control, exacerbation rates, and lung function in a popul...
