Introduction: The use of tobacco and its products has increased in the population over the past two decades, resulting in considerable systemic exposure to nicotine. Aims and Objectives: To estimate and compare the serum nicotine levels among smokers and gutkha chewers, along with the effect of nicotine replacement therapy on serum nicotine levels between them. Materials and Methods: Forty individuals were selected and divided into two groups with 20 individuals in each group. First group included individuals with a smoking habit, whereas the second group included individuals with the habit of chewing gutkha exclusively. Four blood samples were collected from all the participants in both the groups and subjected to serum nicotine estimation. Two blood samples were obtained (first sample after 30 min and the next sample after 60 min following smoking/chewing) on the first day, and the other two were obtained after 24 h of tobacco abstinence (after 24 h all the participants were asked to chew nicotine chewing gums each containing 2 mg of nicotine). Statistical Analysis Used: The particulars of age, frequency of habit (smoking and chewing gutkha), and serum nicotine levels before and after replacement therapy (nicotine chewing gum) were recorded and analyzed statistically by cross-tabulation for calculation of mean and frequency. Results: The serum concentration of nicotine in smokers at 30 min after smoking ranged 120-309 ng/ml and at 60 min ranged 29-77 ng/ml. In group 1, individuals' serum nicotine concentration after replacement therapy with nicotine chewing gum ranged 29-77 ng/ml at 30 min and 1-6 ng/ml at 60 min. Serum concentration of nicotine at 30 min after chewing gutkha ranged 86-200 ng/ml and at 60 min ranged 61-102 ng/ml. The serum nicotine concentration in group 2 individuals at 30 min following chewing nicotine gum ranged 24-55 ng/ml and at 60 min ranged 0-3 ng/ml. Conclusion: Serum nicotine concentration in chewers was less at 30 min and 60 min after chewing gutkha compared to smokers. Serum concentration after replacement therapy in chewers was slightly reduced after 30 min and considerably reduced after 60 min of chewing nicotine gum compared to smokers, indicating that nicotine levels were more in smokers than chewers and replacement therapy is effective in chewers than in smokers.
