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 2012-2013 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.
a Difference between the 2002-2003 estimate and the 2012-2013 estimate is statistically significant at the 0.05 level.
b Difference between the 2002-2003 estimate and the 2012-2013 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 2012-2013 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
NOTE: Average annual initiation of marijuana (%) = 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 individuals 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 2012-2013 estimate is statistically significant at the 0.05 level.
b Difference between the 2002-2003 estimate and the 2012-2013 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 2012-2013 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 2012-2013 estimate is statistically significant at the 0.05 level.
b Difference between the 2002-2003 estimate and the 2012-2013 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 2012-2013 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 2012-2013 estimate is statistically significant at the 0.05 level.
b Difference between the 2002-2003 estimate and the 2012-2013 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 2012-2013 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 2012-2013 estimate is statistically significant at the 0.05 level.
b Difference between the 2002-2003 estimate and the 2012-2013 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 2012-2013 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 2012-2013 estimate is statistically significant at the 0.05 level.
b Difference between the 2002-2003 estimate and the 2012-2013 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 2012-2013 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 2012-2013 estimate is statistically significant at the 0.05 level.
b Difference between the 2002-2003 estimate and the 2012-2013 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 2012-2013 Small Area Estimates

To determine whether the differences between the 2002-2003 and 2012-2013 National Survey on Drug Use and Health (NSDUH) State prevalence rates are statistically significant, let pi 1 sub s and a and pi 2 sub s and a denote the 2002-2003 and 2012-2013 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 (lor sub s and a) as opposed to the simple difference because the posterior distribution of 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 2012-2013 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 tables in this document (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 2012 2013 State estimates presented in Tables 1 to 22 and elsewhere at http://www.samhsa.gov/data/population-data-nsduh/reports?tab=33. 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 2012-2013 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 2012-2013 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 2012-2013), 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 (based on some empirical studies carried out earlier) 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 capital 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.

Long description, Equation 2. The estimate of the log-odds ratio, lor hat sub s and a, is defined as the natural logarithm of the ratio of two quantities. The numerator of the ratio is p 2 sub s and a divided by 1 minus p 2 sub s and a. The denominator of the ratio is p 1 sub s and a divided by 1 minus p 1 sub s and a, where p 1 sub s and a are the 2002-2003 State estimates and p 2 sub s and a are the 2012-2013 State estimates.

Long description, Equation 3. Variance v of the estimate of the log-odds ratio, lor hat sub s and a, is a function of three quantities: q1, q2, and q3. It is expressed as the sum of q1 and q2 minus q3. Quantity q1 is the variance v of the natural logarithm of Theta 1 hat, quantity q2 is the variance v of the natural logarithm of Theta 2 hat, and quantity q3 is 2 times the covariance between the natural logarithm of Theta 1 hat and the natural logarithm of Theta 2 hat.

Long description, Equation 4. The covariance between the natural logarithm of Theta 1 hat and the natural logarithm of Theta 2 hat is equal to the correlation between the natural logarithm of Theta 1 hat and the natural logarithm of Theta 2 hat multiplied by the square root of the product of the variance v of the natural logarithm of Theta 1 hat and the variance v of the natural logarithm of Theta 2 hat.
