Enlisting Peer Cooperation in the Service of Alcohol Use Prevention in Middle School

This article reports on a cluster randomized trial of cooperative learning (CL) as a way to prevent escalation in alcohol use during middle school (N = 1,460 seventh‐grade students, age 12–13, seven intervention and eight control schools). We hypothesized that CL, by bringing students together in group‐based learning activities using positive interdependence, would interrupt the process of deviant peer clustering, provide at‐risk youth with prosocial influences, and in turn, reduce escalations in alcohol use. Results indicated that CL significantly reduced growth in deviant peer affiliation and actual alcohol use, and effects for willingness to use alcohol were at the threshold of significance (p = .05). CL also attenuated the link between willingness to use alcohol and later alcohol use.

Whatever your personal position on the subject of marijuana legalization, whether for medical or recreational use, a growing body of research reveals concerns over the potential harms caused by cannabis. The concerns are more than academic. With increasing public support (varying by demographic cohorts) for legalized marijuana, and 10 states legalizing recreational marijuana and 33 states where medical marijuana use is legal, the cannabis movement is just gaining steam. A new Pew Research Center report shows that 6 in 10 Americans (62 percent) say marijuana should be legal. Millennials support legalized marijuana more tha...

ConclusionsIn female, but not male rats, an appetitive conditioning history with nicotine decreases methamphetamine, but not alcohol, self-administration. This dissociation suggests that the effects may be due to a specific increase in the reinforcing value of methamphetamine. This may have implications for better understanding the progression of drug use from nicotine to methamphetamine.

The ethanolic extracts of Bacopa monnieri (BME) are used in Indian traditional medicines for the management of alcoholic disorders. However, the underlying mechanism(s) associated with the influence of BME on alcohol abstinence-induced anxiety-like behavior have not been adequately addressed. Therefore, the present study was planned to examine the beneficial effects of BME in alc...

The experiment has shown that only non‑hydrogen-bonded alcohol molecules were present in the sample at 10 K. Conformational analysis using high-level ROCBS-QB3 ab-initio calculations has shown that only 111 of 122 1-hexanol conformers can exist. The most stable conformer was determ...
