Findings indicate that both are associated with high-school student alcohol use and binge drinking.
Alcohol use that begins during adolescence affects the development of alcohol use disorders during adulthood. A new study looks at the effects of interplay between peer drinking and the functional variant rs1229984 in the alcohol dehydrogenase 1B gene (ADH1B) among adolescents.

The magnitude of these effects is much larger than effects for established risk factors for future weight gain, such as parental obesity.
