Aim: To determine the Nicotine concentration and pH in commercially available brands of Cigarettes and Bidis. Materials and Methods: Tobacco products were obtained from the local markets. Pure form of Nicotine was used as standard which was obtained from Sigma Aldrich Chemicals. Nicotine was extracted and the concentration was estimated by Spectrophotometer. lgm of nicotine was suspended in 20 m1 of distilled water and pH was estimated using a pH meter, after 30 minutes. Statistical analysis was done using t-Test and p < 0.05 was selected in describing the level of significance. Results: The analyses shows that Nicotine Concentration was more in Bidi compared to Cigarettes and was found to be statistically significant (p < 0.05), the pH was more in Bidi when compared to Cigarettes. Conclusions: The study results show a substantial difference in nicotine concentration in Bidi and Cigarettes, but there was no significant difference in the pH of Bidi and Cigarettes. However the addictive potential of tobacco products may be controlled by altering the pH, size of tobacco, use of filter.
