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 2002-2003 and the 2008-2009 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 estimates published prior to 2012 due to updates (see Section 1.5 of the report on State Estimates of Substance Use and Mental Disorders from the 2009-2010 NSDUHs).
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 2002-2003 estimate and the 2008-2009 estimate is statistically significant at the 0.05 level.
b Difference between the 2002-2003 estimate and the 2008-2009 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 2002-2003 and the 2008-2009 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 estimates published prior to 2012 due to updates (see Section 1.5 of the report on State Estimates of Substance Use and Mental Disorders from the 2009-2010 NSDUHs).
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 2002-2003 estimate and the 2008-2009 estimate is statistically significant at the 0.05 level.
b Difference between the 2002-2003 estimate and the 2008-2009 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 2002-2003 and the 2008-2009 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 estimates published prior to 2012 due to updates (see Section 1.5 of the report on State Estimates of Substance Use and Mental Disorders from the 2009-2010 NSDUHs).
a Difference between the 2002-2003 estimate and the 2008-2009 estimate is statistically significant at the 0.05 level.
b Difference between the 2002-2003 estimate and the 2008-2009 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 2002-2003 and the 2008-2009 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 estimates published prior to 2012 due to updates (see Section 1.5 of the report on State Estimates of Substance Use and Mental Disorders from the 2009-2010 NSDUHs).
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 2002-2003 estimate and the 2008-2009 estimate is statistically significant at the 0.05 level.
b Difference between the 2002-2003 estimate and the 2008-2009 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 2002-2003 and the 2008-2009 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
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.
NOTE: The 2008-2009 estimates may differ from estimates published prior to 2012 due to updates (see Section 1.5 of the report on State Estimates of Substance Use and Mental Disorders from the 2009-2010 NSDUHs).
a Difference between the 2002-2003 estimate and the 2008-2009 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 2002-2003 and the 2008-2009 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 estimates published prior to 2012 due to updates (see Section 1.5 of the report on State Estimates of Substance Use and Mental Disorders from the 2009-2010 NSDUHs).
a Difference between the 2002-2003 estimate and the 2008-2009 estimate is statistically significant at the 0.05 level.
b Difference between the 2002-2003 estimate and the 2008-2009 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 2002-2003 and the 2008-2009 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 estimates published prior to 2012 due to updates (see Section 1.5 of the report on State Estimates of Substance Use and Mental Disorders from the 2009-2010 NSDUHs).
a Difference between the 2002-2003 estimate and the 2008-2009 estimate is statistically significant at the 0.05 level.
b Difference between the 2002-2003 estimate and the 2008-2009 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 2002-2003 and the 2008-2009 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 estimates published prior to 2012 due to updates (see Section 1.5 of the report on State Estimates of Substance Use and Mental Disorders from the 2009-2010 NSDUHs).
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 2002-2003 and the 2008-2009 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 estimates published prior to 2012 due to updates (see Section 1.5 of the report on State Estimates of Substance Use and Mental Disorders from the 2009-2010 NSDUHs).
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 is based on the definition found in the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV).
a Difference between the 2002-2003 estimate and the 2008-2009 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 2002-2003 and the 2008-2009 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 estimates published prior to 2012 due to updates (see Section 1.5 of the report on State Estimates of Substance Use and Mental Disorders from the 2009-2010 NSDUHs).
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 2002-2003 estimate and the 2008-2009 estimate is statistically significant at the 0.05 level.
b Difference between the 2002-2003 estimate and the 2008-2009 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 2002-2003 and the 2008-2009 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 estimates published prior to 2012 due to updates (see Section 1.5 of the report on State Estimates of Substance Use and Mental Disorders from the 2009-2010 NSDUHs).
NOTE: Needing But Not Receiving Treatment refers to respondents classified as needing treatment for alcohol, but not receiving treatment for an alcohol problem at a specialty facility (i.e., drug and alcohol rehabilitation facilities [inpatient or outpatient], hospitals [inpatient only], and mental health centers).
a Difference between the 2002-2003 estimate and the 2008-2009 estimate is statistically significant at the 0.05 level.
b Difference between the 2002-2003 estimate and the 2008-2009 estimate is statistically significant at the 0.10 level.

Methodology Used to Estimate the Bayes Posterior Probability of No Change between the 2002-2003 and 2008-2009 Small Area Estimates

To determine if the differences between the 2002-2003 and 2008-2009 State prevalence rates are statistically significant, let pi 1 sub s and a and pi 2 sub s and a denote 2002-2003 and 2008-2009 prevalence rates, respectively, for State-s and age group-a. The difference between pi 1 sub s and a and pi 2 sub s and a is defined in terms of the log-odds ratio (l o r sub s and a) as opposed to the simple difference because the posterior distribution of l o r sub s and a is closer to Gaussian than the posterior distribution of the simple difference (Pi 2 sub s and a minus pi 1 sub s and a represents the simple difference between the 2008-2009 and 2002-2003 prevalence rates.). The difference estimator l o r sub s and a is defined as

Equation 1,     D


where ln is the natural logarithm. The p value given in Tables 1 to 22 is computed to test the null hypothesis of no change (i.e., Pi 2 sub s and a is equal to pi 1 sub s and a or equivalently, Log-odds ratio, lor sub s and a, is equal to zero). An estimate of l o r sub s and a is given by

Equation 2,     D


where p 1 sub s and a are the previously published 2002-2003 State estimates1 and p 2 sub s and a are the 2008-2009 State estimates. To compute the variance of estimates the estimate of the log-odds ratio, lor hat sub s and a, that is, variance v of the estimate of the log-odds ratio, lor hat sub s and a, let Theta 1 hat equal the ratio of p 1 sub s and a and 1 minus p 1 sub s and a and Theta 2 hat equal the ratio of p 2 sub s and a and 1 minus p 2 sub s and a, then

Equation 3,     D

where covariance between the natural logarithm of Theta 1 hat and the natural logarithm of Theta 2 hat denotes the covariance between natural logarithm of Theta 1 hat and natural logarithm of Theta 2 hat. This covariance is defined in terms of the associated correlation as follows:

Equation 4.     D

Note that variance v of the natural logarithm of Theta 1 hat and variance v of the natural logarithm of Theta 2 hat used here to calculate variance v of the estimate of the log-odds ratio, lor hat sub s and a are the same variances used in calculating the previously published 2002-2003 Bayesian confidence intervals and the 2008-2009 Bayesian confidence intervals, respectively.

The correlation between natural logarithm of Theta 1 hat and natural logarithm of Theta 2 hat was obtained by simultaneously modeling the pooled 2002-2003 and pooled 2008-2009 National Survey on Drug Use and Health (NSDUH) data. For this simultaneous model, four age groups (12 to 17, 18 to 25, 26 to 34, and 35 or older) by two time periods (2002-2003 and 2008-2009), that is, eight subpopulation-specific models, were fitted, each with its own set of fixed and random effects. In this case, the general covariance matrices for the State and within-State random effects were 8 × 8 matrices corresponding to the eight element (age group × time period) vectors of random effects.

To calculate the p value for testing the null hypothesis of no difference ([Log-odds ratio lor is equal to zero), it is assumed that the posterior distribution of log-odds ratio lor is normal with Mean is equal to the estimate of the log-odds ratio, lor hat sub s and a and Variance is equal to the variance v of the estimate of the log-odds ratio, lor hat sub s and a. With the null value of ([Log-odds ratio lor is equal to zero), the Bayes p value or posterior probability of no difference is The p value is equal to 2 times the probability of realizing a standard normal variate greater than or equal to the absolute value of a quantity z, where Z is a standard normal random variate, Quantity z is the estimate of the log-odds ratio, lor hat sub s and a, divided by the square root of the variance v of the estimate of the log-odds ratio, lor hat sub s and a, and absolute value of quantity z denotes the absolute value of quantity z.


During regular data collection and processing checks for the 2011 NSDUH, data errors were identified. These errors affected the data for Pennsylvania (2006 to 2010) and Maryland (2008 and 2009). Cases with erroneous data were removed from the data files, and the remaining cases were reweighted to provide representative estimates. Therefore, some estimates using 2006 to 2010 NSDUH data (including the 2008-2009 small area estimates shown in these tables) will differ from corresponding estimates found in some previous reports.2 All of the source lines in these tables have a note that includes the text "(Revised March 2012)" to indicate that the 2008-2009 small area estimates are based on revised NSDUH data. However, the correlation shown in the covariance term above was not based on revised data. All other estimates used in the p value calculations, including the prevalence rates and variances, were based on revised data. Tests based on several outcome measures indicated that revising the correlations did not affect the p values greatly; hence, a decision was made by SAMHSA's Center for Behavioral Health Statistics and Quality not to redo the correlations.
