Introduction : Tobacco smoking in India has been increasing alarmingly. Aims and Objectives: The present work is undertaken to study the effect of 2-5 years of tobacco smoking on ventilatory functions.

Material and Methods: The study group consisted of 25 male, young, healthy medical students, free from cardiopulmonary diseases and with history of smoking of 2-5 years duration, on an average of 10 cigarettes per day. The control group consisted of 25 males age matched healthy individuals who had never smoked tobacco. Peak expiratory flow rate is measured using Wright's peak flow meter.

Result : PEFR is decreased in tobacco smoking students compared to non-smoking students. Conclusion:This study shows that 2-5 years of tobacco smoking leads to a definite tendency to narrowing of small airways.

Keywords: Peak expiratory flow rate, smokers, medical students, Wright's peak flow meter.
