Abstract :

Obstructive airway diseases, both chronic obstructive pulmonary disease (COPD) and asthma are leading cause of mortality and morbidity worldwide. Active or passive smoking is being recognized as most important causative factor for COPD. There is no direct relationship of smoking as a cause of asthma in most of the adult patients, however there is enough of evidence for adverse effects of smoking on asthma too.^1,2There are a few reports on smoking relationship with different forms of atopy and asthma. As there is paucity of data, we planned this study to assess the epidemiology of smoking in patients with obstructive lung diseases in India.

Our study population had a male predominance with maximum number of patients in age group of 40–49 years. 60% patients were active smokers, while 29.3% were passive smoker. 48.9% patients were former smokers. 54% patients were bidi smoker while 6% were cigarette smokers. COPD patients had a higher smoking exposure than patients with asthma. Exposure to Environmental Tobacco Smoke (ETS), was also a significant factor for development of COPD and asthma especially in females.
