Research consistently demonstrates that physical activity declines with age. However, such declines do not occur linearly. The transition into early adulthood is one period in which disproportionate declines in physical activity have been evident, but much of our understanding of such declines among young adults has been based on either cross-sectional data or prospective studies that focus exclusively on college/university students. ⋯ Physical activity decline was evident during young adults' transition into early adulthood, with declines being steepest among men who entered a college/university. Although there were increases in several health-risk behaviors during adolescence, individuals tend to grow out of binge drinking and smoking as they mature.

Blunts are hollowed-out cigars or leaf tobacco filled with marijuana. Use of blunts has increased since the 1990s and, in 2005, 3.5% of all American youth were estimated to have used blunts in the past month. Blunt smokers may have greater odds of cannabis and tobacco dependency and are at risk of smoking-related diseases. Previous studies have suggested that blunt use is more common among blacks, older teens, and men. However, data pertaining to blunt use in non-adolescent African-American populations are scarce. ⋯ Blunt use is relatively common among male African Americans aged 19-30 years and is frequently associated with concomitant cigarette use. Tobacco control efforts in this male African-American population should also address blunt usage.
