This survey from the Substance Abuse and Mental Health Services Administration (SAMHSA) showed the rates of recent drinking, binge drinking, and heavy drinking among underaged people continued a decline from 2002. Alcohol use within the past 30 days among 12- to 20-year olds declined from 28.8 percent in 2002 to 25.1 percent in 2011, while binge drinking (consuming five or more drinks on a single occasion on at least one day in the past 30 days) declined from 19.3 percent in 2002 to 15.8 percent in 2011, and heavy drinking declined from 6.2 percent in 2002 to 4.4 percent in 2011. Overall, the use of illicit drugs among Americans age 12 and older remained stable since the last survey in 2010. The survey shows that 22.5 million Americans aged 12 or older were current (past month) illicit drug users—8.7 percent in 2011 versus 8.9 percent in 2010. To download the survey, click here.
