Young adults have the highest prevalence of smoking amongst all age groups. Significant uptake occurs after high school age. Although neighborhood exposures have been found to be associated with smoking behavior, research on neighborhood exposures and the smoking trajectories among young adults, and on the role of geographic scale in shaping findings, is scarce. We examined associations between...

Data from twin studies have suggested that cigarette smoking has a significant heritable component. The serotonin transporter gene (5-HTT) is a plausible candidate gene for smoking predisposition because of its association with psychological traits relevant to smoking behavior. The present investigation evaluated the associations of smoking practices and smoking cessation with a common polymorp...

increased metabolic activity in muscle secondary to excessive muscle activity during the uptake phase and shortly before fdg injection is a known phenomenon. we present fdg pet/ct findings in a young male, known case of carcinoma maxilla his scan showed diffuse increased metabolic activity in multiple skeletal muscle groups. there was history of unaccustomed, strenuous sports activity of skiing...

We examined whether use of snus influenced cognitions in terms of smoking expectancies and smoking prototype perceptions in a direction that could promote smoking initiation, thus highlighting potential causal mechanisms between the use of snus and smoking behavior. A telephone-based longitudinal survey among Norwegian adolescents was conducted with two points of measurement during a 1-year per...

Many researchers have conceptualized smoking uptake behavior in adolescence as progressing through a sequence of developmental stages. Multiple social, psychological, and biological factors influence this process, and may play different functions at different points in the progression, and play different roles for different people. The major objective of this paper is to review empirical studie...
