“…The findings of our study are consistent with previous studies, where the scientists also observed similar trend. 12,17, 18 We have found that there is a significant difference between the decline of peak expiratory flow rate in smokers and non-smokers (p<0.001). The decline of peak expiratory flow rate increases with advancement of age and also with increasing intensity of smoking.…”

INTRODUCTION:There is a clear relationship between the amount of cigarette smoked and mortality. Ironically there is also an increased incidence of cigarette smoking in women all over the world with an increased risk of spontaneous abortion in pregnant women. Although exposure is small as compared with that experienced by mainstream smokers, non-smoking passive smokers, who are in the same room may show pulmonary deposition of smoke particles as well as increased blood levels of nicotine and carboxyhaemoglobin, which became dangerous for infant and children. Smoking cessation is usually associate with improvement of lung functions, that can returns to normal over a period of time. AIMS: To compare the efficiency of lung function in active smokers, passive smokers and after cessation of smoking. MATERIALS AND METHODS: 200 subjects with various age groups ranging from less than 20 years upto 60 years, selected from the relative and attendants of patients attending the outpatient department and indoor wards. They were divided into study and control group. Their lung functions were tested by spirometry with the help of Medispiror. The results obtained were analyzed statistically. STATISTICAL ANALYSIS: the statistical analysis was done by using the formulas of two tail t test. RESULT: There is a highly significant (p<0.001) reduction in pulmonary function parameters in smokers as compared to non-smokers and quitters. Among the pulmonary function parameters the mean forced expiratory flow rates are significantly (respectively p<0.05, p<0.01) less in quitters as compared to non-smokers but FVC, FEV1, PEFR. FEF25-75 are not reduced significantly (p>0.05). CONCLUSION: All the pulmonary functions get worse because of smoking and even passive smoking, which can come back to normal (as in non-smoker) after cessation of smoking, which is a true fact for both the genders.
