Substance Abuse and Mental Health Services Administration (SAMHSA) recently released 2012 National Survey on Drug Use and Health (NSDUH) report – the largest of its kind (70,000 participants throughout the United States), and is the government’s primary vehicle for determining how many persons are using illegal drugs, alcohol, and tobacco, as well as how many are misusing pharmaceuticals.
Although the rate of marijuana use rose in almost every age group, and was up from 5.8% of all Americans in 2007 to 7.3% in 2012, use of this substance dropped slightly for those aged 12 to 17 years.
