NSDUH 2011 survey shows decline in teen drinking: The Substance Abuse and Mental Health Services Administration (SAMHSA) has released the 2011 National Survey on Drug Use and Health (NSDUH). Survey data indicate that rates of past-month drinking among underage Americans continued a decline from 2002. Past-month alcohol use among youths age 12–20 declined from 28.8% in 2002 to 25.1% in 2011, while binge drinking (consuming five or more drinks on a single occasion) declined from 19.3% to 15.8% and heavy drinking declined from 6.2% to 4.4%. Rates of past-month tobacco use by youths age 12 to 17 declined from 15.2% in 2002 to 10.0% in 2011. Overall, illicit drug use among Americans age 12 and older remained unchanged since the 2010 survey: 8.7% (22.5 million people) were past-month illicit drug users in 2011 (8.9% in 2010). Marijuana remains the most commonly used illicit drug; in 2011, 7.0% of Americans were current users, up from 5.8% in 2007. According to the survey report, 21.6 million Americans needed treatment for a substance use problem in 2011 and only 2.3 million (or 10.8% of those in need) received it in a specialized treatment setting, including hospitals (inpatient only), drug or alcohol rehabilitation facilities (inpatient or outpatient), or mental health centers. The survey findings are available on the SAMHSA Web site at www.samhsa.gov/data/NSDUH/2k11Results/NSDUHresults2011.pdf.
