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 2010-2011 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
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 2010-2011 estimate is statistically significant at the 0.05 level.
b Difference between the 2002-2003 estimate and the 2010-2011 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 2010-2011 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
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 2010-2011 estimate is statistically significant at the 0.05 level.
b Difference between the 2002-2003 estimate and the 2010-2011 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 2010-2011 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
a Difference between the 2002-2003 estimate and the 2010-2011 estimate is statistically significant at the 0.05 level.
b Difference between the 2002-2003 estimate and the 2010-2011 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 2010-2011 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 of hours of each other) on at least 1 day in the past 30 days.
a Difference between the 2002-2003 estimate and the 2010-2011 estimate is statistically significant at the 0.05 level.
b Difference between the 2002-2003 estimate and the 2010-2011 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 2010-2011 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.
a Difference between the 2002-2003 estimate and the 2010-2011 estimate is statistically significant at the 0.05 level.
b Difference between the 2002-2003 estimate and the 2010-2011 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 2010-2011 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
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 2002-2003 estimate and the 2010-2011 estimate is statistically significant at the 0.05 level.
b Difference between the 2002-2003 estimate and the 2010-2011 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 2010-2011 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
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.

Methodology Used to Estimate the Bayes Posterior Probability of No Change
between the 2002-2003 and 2010-2011 Small Area Estimates

To estimate changes in the 2002-2003 and 2010-2011 State prevalence rates, let [pi 1 sub s and a] and [pi 2 sub s and a] denote 2002-2003 and 2010-2011 prevalence rates, respectively, for State-s and age group-a. A 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 [lor 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 2010-2011 and 2002-2003 prevalence rates]). The [lor sub s and a] is defined as

Equation 1,     D


where ln denotes the natural logarithm. The p value given in each of the above tables (i.e., 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 [Log-odds ratio lor 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 2010-2011 State estimates presented at http://www.samhsa.gov/data/NSDUH/2k11State/NSDUHsae2011/Index.aspx. To compute the variance of [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 2010-2011 Bayesian confidence intervals given here, 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 2010-2011 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 2010-2011), 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 lor is normal with [Mean is equal to 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 [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 z.
