Pulmonary function test is a routine procedure for the assessment and monitoring of the Respiratory diseases. This study was undertaken to see the effect of smoking on lung function.

Data Collection: Using Pre-designed questionnaire, information on Socio-demographic profile, history of Smoking, anthropometric measurements  height, weight,  FEV1 recording  using Wrights Peak Flow Meter. Data analysis used was SPSS v19.

Results: Mean FEV1 among the smokers was 2.13±1.00  and 2.40±0.51 among the non- smokers; FEV1 was ranging between  150-300 liters in 88.9% of those who had smoked for more than 10yrs of duration, FEV1 value among the smokers was reduced compared to  non –smokers, which was statistically significant (p<0.05.). Significant association was found with duration of smoking and the reduction of FEV1 values.

Conclusions: Smoking causes reduction of FEV1 values, which was significant among the smokers than the Non-smokers.
