Objectives Tobacco and areca nut are two of the most widely used psychoactive plant substances worldwide, yet the biocultural factors that account for variation in use patterns are not well understood. Here we attempt to understand the high prevalence of, and variation in, tobacco and areca nut use among reproductive-aged women. Methods Research was carried out in Mysore, Karnataka, India. First, we conducted a qualitative investigation where participants engaged in semistructured interviews and focus group discussions to uncover cultural norms of women's tobacco use. Findings informed the second stage of research which quantitatively tested three models of tobacco and areca nut use (N = 74). Results The qualitative study found that women were more likely to chew "natural" forms of tobacco and areca nut products (kaddipudi and paan). Quantitative tests of our hypotheses revealed that kaddipudi and combined tobacco use were best explained by the self-medication model, with somatic and environmental stress as strong indicators of use. The presence of cotinine, our biological indicator of tobacco use, was best modeled by gender inequality. We also found that men and women reported approximately equal tobacco use, even though their preferred types of tobacco and areca nut products differed. Conclusions Findings did not support the protection hypothesis as it relates to plant toxins. Instead, this study suggests that women might exploit neurotoxins such as nicotine and arecoline to offset the cognitive and energetic costs associated with iron deficiency in stressful environments.

Background and Aim: Tobacco is a leading preventable cause of death which causes death of six millions each year worldwide. One of the most effective methods of preventing this are tobacco counseling sessions as it provides a platform for the patient and the dental professionals to map out a plan for the patient to lead a tobacco free life. Therefore, the study was conducted to assess nicotine dependence, cotinine level and carbon monoxide levels among tobacco users employed in private automobile companies in Chennai. Study Design: Cross-sectional study. Subject and Methods: A cross sectional study of 53 males was conducted among automobile company employees, using simple random sampling technique in Chennai, India. A detailed questionnaire assessing their demographic data, pattern of usage of tobacco, Fagerstrom test for Nicotine Dependence was recorded, carbon monoxide levels were recorded using Smokerlyzer, and presence of urine cotinine was recorded. Descriptive statistics and Chi square test were used to analyze the data. Results: The mean age of the study participants was 31.7 +/- 11.32. Prevalence of smoking tobacco (64.20%) was higher among the study participants. Majority of the smoker study participants were highly dependent on tobacco, according to the FNTD scale. No statistical significance was found between dependency on nicotine and carbon monoxide levels among users of smoking tobacco (p<0.05). A statistical significant association (p<0.05) was found between dependency on nicotine and presence of urine cotinine among smokers. Conclusion: High level of nicotine dependence was observed in the smoker participants, and cotinine in urine was found to be a prominent marker of nicotine among users of smoking tobacco. Carbon monoxide levels were high among people with higher dependency on smoking.
