More than 26% of 12- to 20-year-olds said they consumed alcohol in the month before they participated in the National Survey on Drug Use and Health between 2008 and 2010, according to a Substance Abuse and Mental Health Services Administration report. Almost 9% of the respondents reported purchasing their own alcohol the last time they drank. Researchers found that Vermont had the highest rate of underage drinking, while Utah had the lowest.
