The NIDA-supported Good Behavior Game recently was honored with the 2012 Mentor International Best Practice Award. The game, which focuses on reducing disruptive behaviors in elementary school classrooms, has been shown to prevent drug abuse and other problems in adolescence and young adulthood.
Towns that implemented a drug abuse prevention program called Communities That Care will see a return of $5.30 for each $1 they invested during the 5-year trial of the intervention, according to a cost-benefit analysis. The estimate is based on reductions in smoking and delinquency observed during the fourth year of the study among eighth-graders and the projected total costs of smoking, delinquency, and crime avoided over the lifetimes of study participants.
abril del 2012 Dr. Volkow discusses NIDA’s efforts to develop effective antismoking treatments for populations with persistently high rates of smoking, such as people with psychiatric disorders, high school dropouts, and Native Americans.
Pregnant women who received financial incentives to refrain from smoking during late pregnancy were more successful at remaining abstinent and less likely to have babies with low birth weight, according to data from three trials.
While viewing images of cigarettes, smokers reported milder cravings when they shifted their focus from the pleasures of smoking to its harmful effects. Brain imaging showed a correlation between the reductions in craving and altered activity levels in regions associated with emotional regulation and reward.
New research suggests that differences in tobacco consumption reflect, in part, differences in the functional efficacy of a specific type of receptor in a pathway of the brain. In animal studies, nicotinic acetylcholine receptors with the α5 subunit played a key role in producing aversive responses to nicotine, thereby dissuading further consumption of the drug.
