A new report published last week, "A Day in the Life of American Adolescents," details the self-reported habits of 12-17 year-olds in 2006. The report is the work of the Office of Applied Studies, which is part of the Substance Abuse and Mental Health Services Administration and the federal Department of Health and Human Services.
On an average day in 2006, researchers found that:
Nearly 1.2 million teenagers smoked cigarettes
More than 630,000 drank
Approximately 586,000 used marijuana
To put the numbers in perspective, the nationwide number of adolescents using cigarettes on an average day equals more students than are enrolled in Washington state's K-12 school system.
A short form of the report is also available here.
