NOTE: State and census region estimates are based on a survey-weighted hierarchical Bayes estimation approach, with their p values being the Bayes posterior probability of no change between the 2008-2009 and the 2009-2010 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
NOTE: The 2008-2009 estimates may differ from previously published estimates due to updates (see Section 1.5 of this report).
NOTE: 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. See Section B.4.8 in Appendix B of the Results from the 2008 National Survey on Drug Use and Health: National Findings.
a Difference between the 2008-2009 estimate and the 2009-2010 estimate is statistically significant at the 0.05 level.
b Difference between the 2008-2009 estimate and the 2009-2010 estimate is statistically significant at the 0.10 level.

NOTE: The 2008-2009 estimates may differ from previously published estimates due to updates (see Section 1.5 of this report).
NOTE: Average annual marijuana initiation rate =100 × {[X1 ÷ (0.5 × X1 + X2)] ÷ 2}, where X1 is the number of marijuana initiates in the past 24 months and X2 is the number of persons who never used marijuana. Both of the computation components, X1 and X2, are based on a survey-weighted hierarchical Bayes estimation approach. Note that the age group is based on a respondent's age at the time of the interview, not his or her age at first use.
a Difference between the 2008-2009 estimate and the 2009-2010 estimate is statistically significant at the 0.05 level.
b Difference between the 2008-2009 estimate and the 2009-2010 estimate is statistically significant at the 0.10 level.

NOTE: State and census region estimates are based on a survey-weighted hierarchical Bayes estimation approach, with their p values being the Bayes posterior probability of no change between the 2008-2009 and the 2009-2010 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
NOTE: The 2008-2009 estimates may differ from previously published estimates due to updates (see Section 1.5 of this report).
a Difference between the 2008-2009 estimate and the 2009-2010 estimate is statistically significant at the 0.05 level.
b Difference between the 2008-2009 estimate and the 2009-2010 estimate is statistically significant at the 0.10 level.

NOTE: State and census region estimates are based on a survey-weighted hierarchical Bayes estimation approach, with their p values being the Bayes posterior probability of no change between the 2008-2009 and the 2009-2010 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
NOTE: The 2008-2009 estimates may differ from previously published estimates due to updates (see Section 1.5 of this report).
NOTE: Binge Alcohol Use is defined as drinking five or more drinks on the same occasion (i.e., at the same time or within a couple of hours of each other) on at least 1 day in the past 30 days.
a Difference between the 2008-2009 estimate and the 2009-2010 estimate is statistically significant at the 0.05 level.
b Difference between the 2008-2009 estimate and the 2009-2010 estimate is statistically significant at the 0.10 level.

NOTE: State and census region estimates are based on a survey-weighted hierarchical Bayes estimation approach, with their p values being the Bayes posterior probability of no change between the 2008-2009 and the 2009-2010 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
NOTE: The 2008-2009 estimates may differ from previously published estimates due to updates (see Section 1.5 of this report).
NOTE: Binge Alcohol Use is defined as drinking five or more drinks on the same occasion (i.e., at the same time or within a couple hours of each other) on at least 1 day in the past 30 days.
a Difference between the 2008-2009 estimate and the 2009-2010 estimate is statistically significant at the 0.05 level.
b Difference between the 2008-2009 estimate and the 2009-2010 estimate is statistically significant at the 0.10 level.

NOTE: State and census region estimates are based on a survey-weighted hierarchical Bayes estimation approach, with their p values being the Bayes posterior probability of no change between the 2008-2009 and the 2009-2010 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
NOTE: The 2008-2009 estimates may differ from previously published estimates due to updates (see Section 1.5 of this report).
NOTE: Dependence or abuse is based on definitions found in the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV).
a Difference between the 2008-2009 estimate and the 2009-2010 estimate is statistically significant at the 0.05 level.
b Difference between the 2008-2009 estimate and the 2009-2010 estimate is statistically significant at the 0.10 level.

NOTE: State and census region estimates are based on a survey-weighted hierarchical Bayes estimation approach, with their p values being the Bayes posterior probability of no change between the 2008-2009 and the 2009-2010 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
NOTE: The 2008-2009 estimates may differ from previously published estimates due to updates (see Section 1.5 of this report).
NOTE: 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. See Section B.4.8 in Appendix B of the Results from the 2008 National Survey on Drug Use and Health: National Findings.
NOTE: Dependence or abuse is based on definitions found in the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV).

NOTE: State and census region estimates are based on a survey-weighted hierarchical Bayes estimation approach, with their p values being the Bayes posterior probability of no change between the 2008-2009 and the 2009-2010 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
NOTE: The 2008-2009 estimates may differ from previously published estimates due to updates (see Section 1.5 of this report).
NOTE: Needing But Not Receiving Treatment refers to respondents classified as needing treatment for illicit drugs, but not receiving treatment for an illicit drug problem at a specialty facility (i.e., drug and alcohol rehabilitation facilities [inpatient or outpatient], hospitals [inpatient only], and mental health centers). Illicit Drugs include marijuana/hashish, cocaine (including crack), inhalants, hallucinogens, heroin, or prescription-type psychotherapeutics used nonmedically, including data from original methamphetamine questions but not including new methamphetamine items added in 2005 and 2006. See Section B.4.8 in Appendix B of the Results from the 2008 National Survey on Drug Use and Health: National Findings.
a Difference between the 2008-2009 estimate and the 2009-2010 estimate is statistically significant at the 0.05 level.

NOTE: State and census region estimates are based on a survey-weighted hierarchical Bayes estimation approach, with their p values being the Bayes posterior probability of no change between the 2008-2009 and the 2009-2010 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
NOTE: The 2008-2009 estimates may differ from previously published estimates due to updates (see Section 1.5 of this report).
NOTE: Serious Mental Illness is defined as having a diagnosable mental, behavioral, or emotional disorder, other than a substance use disorder, that met the criteria found in the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) and resulted in serious functional impairment in carrying out major life activities. For details, see Section A.11 in Appendix A of this report.
a Difference between the 2008-2009 estimate and the 2009-2010 estimate is statistically significant at the 0.05 level.

NOTE: The 2008-2009 estimates may differ from previously published estimates due to updates (see Section 1.5 of this report).
NOTE: Major depressive episode is defined as in the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV), which specifies a period of at least 2 weeks when a person experienced a depressed mood or loss of interest or pleasure in daily activities and had a majority of specified depression symptoms. For details, see Section A.11 in Appendix A of this report.
NOTE: There are minor wording differences in the questions in the adult and adolescent major depressive episode modules. Therefore, data from youths aged 12 to 17 were not combined with data from persons aged 18 or older to get an overall estimate (12 or older).
a Difference between the 2008-2009 estimate and the 2009-2010 estimate is statistically significant at the 0.05 level.
