The number of Americans aged 12 or older who used illicit drugs remained steady in 2011, while the rates of binge drinking among underage people continued to decline, HHS' Substance Abuse and Mental Health Services Administration reported Monday.
Statistics from SAMHSA's 2011 National Survey on Drug Use and Health showed that about 22.5 million Americans aged 12 or older—or about 8.7% of that population—used an illicit drug prior to a survey interview, compared with a rate of 8.9% in 2010. Marijuana was the most commonly used illicit drug, with the rate of use rising to 7% in 2011 from 5.8% in 2007.
Meanwhile, the number of heroin users dropped slightly to 620,000 in 2011 from 621,000 in 2010, but the most recent figure is still considerably higher than the 373,000 reported users in 2007. In 2011, there were 1.4 million cocaine users aged 12 or older, just below the 1.5 million cocaine users in 2010.
