Smokers are prone to develop Chronic Obstructive Pulmonary Diseases (COPD) than non-smokers. Chronic Obstructive Pulmonary Diseases (COPD) includes chronic bronchitis, bronchial Asthma, and emphysema. Pulmonary function test is a routine procedure for assessment and monitoring diseases. OBJECTIVE To estimate the Pulmonary function test like Forced Vital Capacity(FVC), Forced Expiratory Volume in one second(FEV???), FEV???/FVC ratio and Peak Expiratory Flow Rate (PEFR)among smokers and non-smokers. Also, to study the effect of age and body mass index (BMI) on the pulmonary function of these groups of people. MATERIAL AND METHOD It is a cross sectional study. The study was conducted among students and staff of Silchar Medical College and Hospital 121 subjects were selected, among them 60 were smokers and 61 non-smokers. Spirometric tests were carried out to assess pulmonary function. EXCLUSIONS CRITERIA Subjects having cardio pulmonary diseases. RESULT Mean FVC, FEV??? and PEFR were found to be of lower value in smokers than non-smokers. There were significant differences between mean spirometric values among smokers and non-smokers. CONCLUSION Pulmonary function declines in smoker
