In recent years, prevalence of smoking among women has been significantly increasing. The aim of this research was to examine the relationships of smoking susceptibility and smoking behavior, specifically in youth teenage girls, in order to have tools for smoking prevention among women. Three studies were conducted in successive years in public and private secondary schools of Mexico City; in total, 1.460 female adolescents participated in them. Psychometric scales were constructed and reconstructed to susceptibility, experimentation and smoking could be measured. In the latest versions of the scales were obtained explained variances > 59% and coefficients a > 0.82. Results showed high and significant coefficients of correlation between susceptibility to smoking and experimentation with tobacco (r = 0.743) as well as smoking (r = 0.424). According to the regression analysis, the susceptibility explained 28.9% of experimentation variance, and 22% of smoking variance, so it is a good predictor of smoking behavior among girls. It was concluded that smoking susceptibility is a measure that can be used reliably to evaluate smoking risk in adolescent women; in this way the prevention efforts will be properly focused on.

Abstract: Ethnopharmacological relevance and Aims: The traditional use of the Hallucinogenic sage, Salvia divinorum has been of ethnopharmalogical interest for some time. This plant, endemic to Oaxaca Mexico and traditionally used by the Mazatec, is now utilized worldwide for its psychoactive effects. This use demonstrates a novel use pattern which is distinctly different from Mazatec use. This study offers a new methodology to study emerging global plant use and assesses the users’ experience with it. The aim of this research was to develop a new methodology to collect and analyze archived data on the World Wide Web, specifically videos which depict Salvia divinorum use. Methods: The basis of the methodology for this project was unobtrusive observation which allows the researcher to observe without influencing the event which is being observed. Qualitative, ethnographic data was used in conjunction with quantitative meta data collected by a customized web crawler programed to archive YouTube™ data. Results: Using this methodology enabled us to understand reported uses and the users’ experiences as expressed on the World Wide Web. The main result of this research was the documentation of a distinct, novel use pattern of Salvia divinorum which has developed outside of Oaxaca; a use pattern which differs in a number of ways from traditional, Mazatec use. The majority of the YouTube™ videos analyzed were found to present indications of a positive Salvia divinorum experience. This result highlighted the contradiction between ethnographic data and what is reported by the media. Finally the representation of Salvia divinorum on YouTube™ (and by inference the WWW as a whole) is a growing phenomena. Conclusions: While anthropological and more specifically medico-anthropological research has, for many years, embraced the dynamics of cultures, until recently, ethnopharmalogical research has generally focused on ‘traditional’ plant use, failing to capture the dynamic elements of plant/human interaction and framing research in the past or as decontextualized largely descriptive reports. Global migration and urban environments formed a basis for looking at the interplay of continuity and change. Such cultural dynamics are exacerbated by the opportunities which the WWW offers.
