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 2004-2005 and the 2005-2006 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
NOTE: The 2005-2006 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 2004-2005 estimate and the 2005-2006 estimate is statistically significant at the 0.05 level.
b Difference between the 2004-2005 estimate and the 2005-2006 estimate is statistically significant at the 0.10 level.

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 2004-2005 estimate and the 2005-2006 estimate is statistically significant at the 0.05 level.
b Difference between the 2004-2005 estimate and the 2005-2006 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 2004-2005 and the 2005-2006 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
NOTE: The 2005-2006 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 2004-2005 estimate and the 2005-2006 estimate is statistically significant at the 0.05 level.
b Difference between the 2004-2005 estimate and the 2005-2006 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 2004-2005 and the 2005-2006 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
NOTE: The 2005-2006 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 2004-2005 estimate and the 2005-2006 estimate is statistically significant at the 0.05 level.
b Difference between the 2004-2005 estimate and the 2005-2006 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 2004-2005 and the 2005-2006 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
NOTE: The 2005-2006 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 hours of each other) on at least 1 day in the past 30 days.
a Difference between the 2004-2005 estimate and the 2005-2006 estimate is statistically significant at the 0.05 level.
b Difference between the 2004-2005 estimate and the 2005-2006 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 2004-2005 and the 2005-2006 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
NOTE: The 2005-2006 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: 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 2004-2005 estimate and the 2005-2006 estimate is statistically significant at the 0.05 level.
b Difference between the 2004-2005 estimate and the 2005-2006 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 2004-2005 and the 2005-2006 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
NOTE: The 2005-2006 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: 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 2004-2005 estimate and the 2005-2006 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 2004-2005 and the 2005-2006 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
NOTE: The 2005-2006 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: Major depressive episode (MDE) 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. MDE data from 2005 and 2006 for adults 18 or older are not comparable. Therefore, only estimates for youths aged 12 to 17 are shown for MDE. For details, see Section A.11 in Appendix A of the report on State Estimates of Substance Use and Mental Disorders from the 2009-2010 NSDUHs.
a Difference between the 2004-2005 estimate and the 2005-2006 estimate is statistically significant at the 0.05 level.
b Difference between the 2004-2005 estimate and the 2005-2006 estimate is statistically significant at the 0.10 level.

Methodology Used to Estimate the Bayes Posterior Probability of
No Change between the 2004-2005 and 2005-2006 Small Area Estimates

Comparisons between State small area estimates displayed in Tables 1 to 23 in this document are based on the 2004 through 2006 National Surveys on Drug Use and Health (NSDUHs). The moving average State prevalence estimates for the overlapping 2004-2005 and 2005-2006 time periods were obtained from independent applications of the survey-weighted hierarchical Bayes (SWHB) methodology; that is, the 2005-2006 models were fit independently of the previously fitted 2004-2005 models. This independent analysis approach was followed because there was no desire to revise the previously published 2004-2005 estimates. Moreover, the same fixed predictor variables were used in the 2004-2005 and 2005-2006 models, but annual updates were made when more current versions became available.1 The age group-specific fixed predictor variables were defined at five levels (namely, the person level, census block group level, tract level, county level, and State level). Also, each age group model had 51 State-level random effects and 300 "within-State" area-level random effects.

To estimate change in State estimates, let pi 1 sub s and a and pi 2 sub s and a denote the 2004-2005 and 2005-2006 prevalence rates, respectively, for State-s and age group-a. The change between pi 1 sub s and a and pi 2 sub s and a is defined in terms of the log-odds ratio (lor sub s and a) as opposed to the simple difference because the posterior distribution of the 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 2005-2006 and 2004-2005 prevalence rates.). The lor sub s and a is defined as

Equation 1,     D


where ln denotes the natural logarithm. The p value given 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 lor sub s and a is given by

Equation 2.     D


where the p 1 sub s and a are previously published 2004-2005 State estimates and the p 2 sub s and a are the 2005-2006 State estimates. To compute the variance of 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 the covariance between the natural logarithm of Theta 1 hat and the natural logarithm of Theta 2 hat denotes the covariance between the natural logarithm of Theta 1 hat and the 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 2004-2005 Bayesian confidence intervals and the 2005-2006 Bayesian confidence intervals, respectively.

The correlation between the natural logarithm of Theta 1 hat and the natural logarithm of Theta 2 hat was obtained by simultaneously modeling the 2004, 2005, and 2006 NSDUH data. This simultaneous modeling approach was adopted based on the results of the validation study2 conducted for measuring change in the 1999-2000 and 2000-2001 State estimates. For this simultaneous model, 4 age groups (12 to 17, 18 to 25, 26 to 34, and 35 or older) by 3 years (2004, 2005, and 2006), that is, 12 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 12 × 12 matrices corresponding to the 12 element (age group × year) vectors of random effects. Note that the survey-weighted, Bernoulli-type log likelihood employed in the SWHB methodology was appropriate for this simultaneous model because the 12 age group × year subpopulations were nonoverlapping. The correlation the natural logarithm of Theta 1 hat and the natural logarithm of Theta 2 hat was approximated by the correlation calculated using the posterior distributions of the natural logarithm of pi 1 sub s and a divided by 1 minus pi 1 sub s and a and the natural logarithm of pi 2 sub s and a divided by 1 minus pi 2 sub s and a from the simultaneous model.

To calculate the p value for testing the null hypothesis of no difference (lor = 0), it is assumed that the posterior distribution of 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 variance v of the estimate of the log-odds ratio, lor hat sub s and a. With the null value of (lor = 0), 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 abs(z) denotes the absolute value of 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 2005-2006 small area estimates shown in these tables) will differ from corresponding estimates found in some previous reports.3 All of the source lines in these tables have a note that includes the text "(Revised March 2012)" to indicate that the 2005-2006 small area estimates are based on revised NSDUH data.
