SAMHSA Report: In 2012, 7.3 
percent of Americans were current users of marijuana – up from 5.8 
percent in 2007. 
Notes from the report: The
 rate of past month nonmedical use of prescription drugs among young 
adults aged 18 to 25 in 2012 was 5.3 percent – similar to rates in 2010 
and 2011, but significantly lower than the rate from 2009 (6.4 percent),
 according to a new report by the Substance Abuse and Mental Health 
Services Administration (SAMHSA). SAMHSA issued its 2012 National Survey on Drug Use and Health (NSDUH) report in conjunction with the 24th annual national observance of National Recovery Month.
The
 SAMHSA report also found that the rates of past month drinking, binge 
drinking and heavy drinking among underage adolescents aged 12 to 17 
remained lower than their levels in 2002 and 2009. The percentage of 
people aged 12 and older who drove under the influence of alcohol at 
least once in the past year in 2012 was 11.2 percent, significantly 
lower than the level in 2002 (14.2 percent) but similar to the rate in 
2011 (11.1 percent).
Overall, the use of illicit drugs among Americans aged 12 and older remained stable since the last survey in 2011. The NSDUH report shows that 23.9 million Americans aged 12 or older were current (past month) illicit drug users – (9.2 percent of the population 12 and older).

Marijuana
 continues to be the most commonly used illicit drug. In 2012, 7.3 
percent of Americans were current users of marijuana – up from 5.8 
percent in 2007. Although past month use of marijuana rose in nearly 
every age group between 2007 and 2012, it did drop among those aged 12 
to 17 from 7.9 percent in 2011 to 7.2 percent in 2012. 
In
 addition to marijuana, the use of heroin also rose significantly. The 
number of people aged 12 and older who used heroin in the past year rose
 from 373,000 in 2007 to 669,000 in 2012. 
The
 report showed some other areas of continued improvement including a 
drop in the rate of past month use of tobacco products among 12 to 17 
year olds – from 15.2 percent in 2002, to 8.6 percent in 2012. Similarly
 between 2002 and 2012, the percentage of youth aged 12 to 17 with 
substance dependence or abuse declined from 8.9 percent to 6.1 percent.
The
 2012 report also showed that many Americans needing treatment for a 
substance use disorder are still not receiving specialty 
treatment. According to the report 23.1 million Americans aged 12 or 
older needed treatment for an illicit drug or alcohol use problem in 
2012 and only 2.5 million (or 10.8 percent of those in need) received it
 in a specialized treatment setting.
NSDUH
 is a scientifically conducted annual survey of approximately 70,000 
people throughout the country, aged 12 and older. Because of its 
statistical power, it is a primary source of statistical information on 
the scope and nature of many substance abuse and mental health issues 
affecting the Nation.
