Table 1 – Needing But Not Receiving Treatment at a Specialty Facility for a Substance Use Problem in the Past Year, by Age Group and State: Percentages, Annual Averages, and P Values from Tests of Differences between Percentages, 2010-2011 and 2011-2012 NSDUHs
State	12+ (2010- 2011)	12+ (2011- 2012)	12+ (P Value)	12-17 (2010- 2011)	12-17 (2011- 2012)	12-17 (P Value)	18-25 (2010- 2011)	18-25 (2011- 2012)	18-25 (P Value)	26+ (2010- 2011)	26+ (2011- 2012)	26+ (P Value)	18+ (2010- 2011)	18+ (2011- 2012)	18+ (P Value)
NOTE: State and census region estimates are based on a survey-weighted hierarchical Bayes estimation approach, with their p values being the Bayes significance levels for the null hypothesis of no change between the 2010-2011 and 2011-2012 population percentages. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods. NOTE: Needing But Not Receiving Treatment refers to respondents classified as needing treatment for a substance use problem, but not receiving treatment for an illicit drug or alcohol problem at a specialty facility (i.e., drug and alcohol rehabilitation facility [inpatient or outpatient], hospital [inpatient only], or mental health center). Illicit Drugs include marijuana/hashish, cocaine (including crack), heroin, hallucinogens, inhalants, or prescription-type psychotherapeutics used nonmedically, including data from original methamphetamine questions but not including new methamphetamine items added in 2005 and 2006. ^a Difference between the 2010-2011 and 2011-2012 population percentages is statistically significant at the 0.05 level. ^b Difference between the 2010-2011 and 2011-2012 population percentages is statistically significant at the 0.10 level.
