Although the influence of peers on adolescent smoking should vary depending on social dynamics, there is a lack of understanding of which elements are most crucial and how this dynamic unfolds for smoking initiation and continuation across areas of the world. The present meta-analysis included 75 studies yielding 237 effect sizes that examined associations between peers' smoking and adolescents...

Although there is clearly an inverse relationship between smoking and body weight, recent studies suggest that weight attenuation via smoking is slow and may take decades to accrue. This investigation prospectively evaluated the relationships between smoking dosage (or lack thereof) and relative weight change in 1697 adolescents followed over 4 years. A 4 (smoking groups: 0, 1, 2, or 3 or more ...
