NOTE: State and census region estimates are based on a survey-weighted hierarchical Bayes estimation approach, with their p values being the Bayes significance levels for the null hypothesis of no change between the 2012-2013 and 2013-2014 population percentages. 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 2012-2013 and 2013-2014 population percentages is statistically significant at the 0.05 level.
b Difference between the 2012-2013 and 2013-2014 population percentages 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 significance levels for the null hypothesis of no change between the 2012-2013 and 2013-2014 population percentages. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
a Difference between the 2012-2013 and 2013-2014 population percentages is statistically significant at the 0.05 level.
b Difference between the 2012-2013 and 2013-2014 population percentages 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 significance levels for the null hypothesis of no change between the 2012-2013 and 2013-2014 population percentages. 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 (with the at-risk population defined as 0.5 × X1 + X2). Both of the computation components, X1 and X2, are based on a survey-weighted hierarchical Bayes estimation approach. The age group shown is based on a respondent's age at the time of the interview, not his or her age at first use. For details, see Section B of the "2011-2012 NSDUH: Guide to State Tables and Summary of Small Area Estimation Methodology" at http://www.samhsa.gov/data/.

NOTE: State and census region estimates are based on a survey-weighted hierarchical Bayes estimation approach, with their p values being the Bayes significance levels for the null hypothesis of no change between the 2012-2013 and 2013-2014 population percentages. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
NOTE: Illicit Drugs Other Than Marijuana include 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 2012-2013 and 2013-2014 population percentages is statistically significant at the 0.05 level.
b Difference between the 2012-2013 and 2013-2014 population percentages 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 significance levels for the null hypothesis of no change between the 2012-2013 and 2013-2014 population percentages. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
a Difference between the 2012-2013 and 2013-2014 population percentages is statistically significant at the 0.05 level.
b Difference between the 2012-2013 and 2013-2014 population percentages 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 significance levels for the null hypothesis of no change between the 2012-2013 and 2013-2014 population percentages. 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 2012-2013 and 2013-2014 population percentages is statistically significant at the 0.05 level.
b Difference between the 2012-2013 and 2013-2014 population percentages 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 significance levels for the null hypothesis of no change between the 2012-2013 and 2013-2014 population percentages. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
NOTE: Tobacco Products include cigarettes, smokeless tobacco (i.e., chewing tobacco or snuff), cigars, or pipe tobacco.
a Difference between the 2012-2013 and 2013-2014 population percentages is statistically significant at the 0.05 level.
b Difference between the 2012-2013 and 2013-2014 population percentages 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 significance levels for the null hypothesis of no change between the 2012-2013 and 2013-2014 population percentages. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
a Difference between the 2012-2013 and 2013-2014 population percentages is statistically significant at the 0.05 level.
b Difference between the 2012-2013 and 2013-2014 population percentages 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 significance levels for the null hypothesis of no change between the 2012-2013 and 2013-2014 population percentages. 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.
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 2012-2013 and 2013-2014 population percentages is statistically significant at the 0.05 level.
b Difference between the 2012-2013 and 2013-2014 population percentages 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 significance levels for the null hypothesis of no change between the 2012-2013 and 2013-2014 population percentages. 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.
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 2012-2013 and 2013-2014 population percentages 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 significance levels for the null hypothesis of no change between the 2012-2013 and 2013-2014 population percentages. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
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], or 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.
a Difference between the 2012-2013 and 2013-2014 population percentages is statistically significant at the 0.05 level.
b Difference between the 2012-2013 and 2013-2014 population percentages 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 significance levels for the null hypothesis of no change between the 2012-2013 and 2013-2014 population percentages. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
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], or mental health centers).
a Difference between the 2012-2013 and 2013-2014 population percentages is statistically significant at the 0.05 level.
b Difference between the 2012-2013 and 2013-2014 population percentages 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 significance levels for the null hypothesis of no change between the 2012-2013 and 2013-2014 population percentages. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
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. For details, see Section B of the "2011-2012 NSDUH: Guide to State Tables and Summary of Small Area Estimation Methodology" at http://www.samhsa.gov/data/.
NOTE: There are minor wording differences in the questions in the adult and adolescent MDE modules. Therefore, data from youths aged 12 to 17 were not combined with data from adults aged 18 or older to produce an estimate for those aged 12 or older.
a Difference between the 2012-2013 and 2013-2014 population percentages is statistically significant at the 0.05 level.

Methodology Used to Estimate the Bayes
Significance Level for the Null Hypothesis of No Change between the
2012-2013 and 2013-2014 Population Percentages

Comparisons between the state population percentages displayed in Tables 1 to 26 in this document are based on the 2012 through 2014 National Surveys on Drug Use and Health (NSDUHs). The moving average state estimates for the overlapping 2012-2013 and 2013-2014 time periods were obtained from independent applications of the survey-weighted hierarchical Bayes (SWHB) methodology; that is, the 2013-2014 models were fit independently of the previously fitted 2012-2013 models. This independent analysis approach was followed because there was no desire to revise the previously published 2012-2013 estimates. Moreover, the same fixed predictor variables were used in the 2012-2013 and 2013-2014 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 250 "within-state" area-level random effects.2

To estimate change in state population percentages, let pi 1 sub s and a and pi 2 sub s and a denote the 2012-2013 and 2013-2014 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 log-odds ratio, 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 2013-2014 and 2012-2013 prevalence rates.) The log-odds ratio, 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 log-odds ratio, lor sub s and a is given by

Equation 2,     D


where the p 1 sub s and a represents the previously published 2012-2013 state estimates and the p 2 sub s and a represents the 2013-2014 state estimates. 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 2012-2013 Bayesian confidence intervals and the 2013-2014 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 2012, 2013, and 2014 NSDUH data. This simultaneous modeling approach was adopted based on the results of the validation study3 conducted for measuring change in the 1999-2000 and 2000-2001 state population percentages. For this simultaneous model, 4 age groups (12 to 17, 18 to 25, 26 to 34, and 35 or older) by 3 years (2012, 2013, and 2014), 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 effects4 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 correlation between 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 (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 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 (Log-odds ratio lor sub zero equals zero.), the Bayes p value or significance level for the null hypothesis 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.

This Bayesian significance level (or p value) for the null value of log-odds ratio lor, say log-odds ratio lor sub zero, is defined following Rubin5 as the posterior probability for the collection of the log-odds ratio lor values that are less likely or have smaller posterior density d of the log-odds ratio lor than the null (no change) value log-odds ratio lor sub zero. That is, The p value of log-odds ratio lor sub zero is equal to the probability of d of the log-odds ratio lor when it is less than or equal to d of the log-odds ratio lor sub zero.. With the posterior distribution of log-odds ratio lorapproximately normal, the p value of log-odds ratio lor sub zero is given by the above expression.

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.
