National Survey on Drug Use and Health:
Comparison of the 2004-2006 and 2006-2008 Model-Based Substate Estimates

NOTE: The methodology used to conduct significance testing for substate estimates between the 2004-2006 and the 2006-2008 NSDUHs and to calculate p values is provided after Table 22.

-- Not available. These regions were not defined consistently across the two time periods (i.e., 2004-2006 and 2006-2008); hence, the 2004-2006 estimates and p values are not available for these regions. The definitions of the substate regions listed in this table are provided in the "2006-2008 National Survey on Drug Use and Health Substate Region Definitions" at http://www.samhsa.gov/data/NSDUH/substate2k08/toc.aspx.
NOTE: The 2006-2008 estimates may differ from previously published estimates due to updates in the region definitions (using the 2008-2010 substate region definitions) and updates to the data. For details, see the "2006-2008 National Survey on Drug Use and Health: Guide to Substate Tables and Summary of Small Area Estimation Methodology" at http://www.samhsa.gov/data/NSDUH/substate2k08/toc.aspx.
NOTE: Substate, State, and census region estimates, along with the 95 percent Bayesian confidence (credible) intervals, are based on a survey-weighted hierarchical Bayes estimation approach and are generated by Markov Chain Monte Carlo techniques, with their p values being the Bayes posterior probability of no change between the 2004-2006 and 2006-2008 estimates. The "Total United States" estimates, along with the 95 percent confidence intervals (CIs) and p values, are based on design-based (direct) estimation methods. Note that the 2004-2006 CIs included in these tables for the "Total United States" row are design-based CIs rather than model-based CIs published in prior 2004-2006 substate tables.
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 2004-2006 estimate and the 2006-2008 estimate is statistically significant at the 0.05 level.
b Difference between the 2004-2006 estimate and the 2006-2008 estimate is statistically significant at the 0.10 level.
1 Names of some of the substate regions for this State have changed across the two time periods (2004-2006 vs. 2006-2008). For details, see the "2006-2008 National Survey on Drug Use and Health Substate Region Definitions" at http://www.samhsa.gov/data/NSDUH/substate2k08/toc.aspx.

-- Not available. These regions were not defined consistently across the two time periods (i.e., 2004-2006 and 2006-2008); hence, the 2004-2006 estimates and p values are not available for these regions. The definitions of the substate regions listed in this table are provided in the "2006-2008 National Survey on Drug Use and Health Substate Region Definitions" at http://www.samhsa.gov/data/NSDUH/substate2k08/toc.aspx.
NOTE: The 2006-2008 estimates may differ from previously published estimates due to updates in the region definitions (using the 2008-2010 substate region definitions) and updates to the data. For details, see the "2006-2008 National Survey on Drug Use and Health: Guide to Substate Tables and Summary of Small Area Estimation Methodology" at http://www.samhsa.gov/data/NSDUH/substate2k08/toc.aspx.
NOTE: Substate, State, and census region estimates, along with the 95 percent Bayesian confidence (credible) intervals, are based on a survey-weighted hierarchical Bayes estimation approach and are generated by Markov Chain Monte Carlo techniques, with their p values being the Bayes posterior probability of no change between the 2004-2006 and 2006-2008 estimates. The "Total United States" estimates, along with the 95 percent confidence intervals (CIs) and p values, are based on design-based (direct) estimation methods. Note that the 2004-2006 CIs included in these tables for the "Total United States" row are design-based CIs rather than model-based CIs published in prior 2004-2006 substate tables.
a Difference between the 2004-2006 estimate and the 2006-2008 estimate is statistically significant at the 0.05 level.
b Difference between the 2004-2006 estimate and the 2006-2008 estimate is statistically significant at the 0.10 level.
1 Names of some of the substate regions for this State have changed across the two time periods (2004-2006 vs. 2006-2008). For details, see the "2006-2008 National Survey on Drug Use and Health Substate Region Definitions" at http://www.samhsa.gov/data/NSDUH/substate2k08/toc.aspx.

-- Not available. These regions were not defined consistently across the two time periods (i.e., 2004-2006 and 2006-2008); hence, the 2004-2006 estimates and p values are not available for these regions. The definitions of the substate regions listed in this table are provided in the "2006-2008 National Survey on Drug Use and Health Substate Region Definitions" at http://www.samhsa.gov/data/NSDUH/substate2k08/toc.aspx.
NOTE: The 2006-2008 estimates may differ from previously published estimates due to updates in the region definitions (using the 2008-2010 substate region definitions) and updates to the data. For details, see the "2006-2008 National Survey on Drug Use and Health: Guide to Substate Tables and Summary of Small Area Estimation Methodology" at http://www.samhsa.gov/data/NSDUH/substate2k08/toc.aspx.
NOTE: Substate, State, and census region estimates, along with the 95 percent Bayesian confidence (credible) intervals, are based on a survey-weighted hierarchical Bayes estimation approach and are generated by Markov Chain Monte Carlo techniques, with their p values being the Bayes posterior probability of no change between the 2004-2006 and 2006-2008 estimates. The "Total United States" estimates, along with the 95 percent confidence intervals (CIs) and p values, are based on design-based (direct) estimation methods. Note that the 2004-2006 CIs included in these tables for the "Total United States" row are design-based CIs rather than model-based CIs published in prior 2004-2006 substate tables.
a Difference between the 2004-2006 estimate and the 2006-2008 estimate is statistically significant at the 0.05 level.
b Difference between the 2004-2006 estimate and the 2006-2008 estimate is statistically significant at the 0.10 level.
1 Names of some of the substate regions for this State have changed across the two time periods (2004-2006 vs. 2006-2008). For details, see the "2006-2008 National Survey on Drug Use and Health Substate Region Definitions" at http://www.samhsa.gov/data/NSDUH/substate2k08/toc.aspx.

-- Not available. These regions were not defined consistently across the two time periods (i.e., 2004-2006 and 2006-2008); hence, the 2004-2006 estimates and p values are not available for these regions. The definitions of the substate regions listed in this table are provided in the "2006-2008 National Survey on Drug Use and Health Substate Region Definitions" at http://www.samhsa.gov/data/NSDUH/substate2k08/toc.aspx.
NOTE: The 2006-2008 estimates may differ from previously published estimates due to updates in the region definitions (using the 2008-2010 substate region definitions) and updates to the data. For details, see the "2006-2008 National Survey on Drug Use and Health: Guide to Substate Tables and Summary of Small Area Estimation Methodology" at http://www.samhsa.gov/data/NSDUH/substate2k08/toc.aspx.
NOTE: Substate, State, and census region estimates, along with the 95 percent Bayesian confidence (credible) intervals, are based on a survey-weighted hierarchical Bayes estimation approach and are generated by Markov Chain Monte Carlo techniques, with their p values being the Bayes posterior probability of no change between the 2004-2006 and 2006-2008 estimates. The "Total United States" estimates, along with the 95 percent confidence intervals (CIs) and p values, are based on design-based (direct) estimation methods. Note that the 2004-2006 CIs included in these tables for the "Total United States" row are design-based CIs rather than model-based CIs published in prior 2004-2006 substate tables.
a Difference between the 2004-2006 estimate and the 2006-2008 estimate is statistically significant at the 0.05 level.
b Difference between the 2004-2006 estimate and the 2006-2008 estimate is statistically significant at the 0.10 level.
1 Names of some of the substate regions for this State have changed across the two time periods (2004-2006 vs. 2006-2008). For details, see the "2006-2008 National Survey on Drug Use and Health Substate Region Definitions" at http://www.samhsa.gov/data/NSDUH/substate2k08/toc.aspx.

-- Not available. These regions were not defined consistently across the two time periods (i.e., 2004-2006 and 2006-2008); hence, the 2004-2006 estimates and p values are not available for these regions. The definitions of the substate regions listed in this table are provided in the "2006-2008 National Survey on Drug Use and Health Substate Region Definitions" at http://www.samhsa.gov/data/NSDUH/substate2k08/toc.aspx.
NOTE: The 2006-2008 estimates may differ from previously published estimates due to updates in the region definitions (using the 2008-2010 substate region definitions) and updates to the data. For details, see the "2006-2008 National Survey on Drug Use and Health: Guide to Substate Tables and Summary of Small Area Estimation Methodology" at http://www.samhsa.gov/data/NSDUH/substate2k08/toc.aspx.
NOTE: Substate, State, and census region estimates, along with the 95 percent Bayesian confidence (credible) intervals, are based on a survey-weighted hierarchical Bayes estimation approach and are generated by Markov Chain Monte Carlo techniques, with their p values being the Bayes posterior probability of no change between the 2004-2006 and 2006-2008 estimates. The "Total United States" estimates, along with the 95 percent confidence intervals (CIs) and p values, are based on design-based (direct) estimation methods. Note that the 2004-2006 CIs included in these tables for the "Total United States" row are design-based CIs rather than model-based CIs published in prior 2004-2006 substate tables.
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. 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 2004-2006 estimate and the 2006-2008 estimate is statistically significant at the 0.05 level.
b Difference between the 2004-2006 estimate and the 2006-2008 estimate is statistically significant at the 0.10 level.

-- Not available. These regions were not defined consistently across the two time periods (i.e., 2004-2006 and 2006-2008); hence, the 2004-2006 estimates and p values are not available for these regions. The definitions of the substate regions listed in this table are provided in the "2006-2008 National Survey on Drug Use and Health Substate Region Definitions" at http://www.samhsa.gov/data/NSDUH/substate2k08/toc.aspx.
NOTE: The 2006-2008 estimates may differ from previously published estimates due to updates in the region definitions (using the 2008-2010 substate region definitions) and updates to the data. For details, see the "2006-2008 National Survey on Drug Use and Health: Guide to Substate Tables and Summary of Small Area Estimation Methodology" at http://www.samhsa.gov/data/NSDUH/substate2k08/toc.aspx.
NOTE: Substate, State, and census region estimates, along with the 95 percent Bayesian confidence (credible) intervals, are based on a survey-weighted hierarchical Bayes estimation approach and are generated by Markov Chain Monte Carlo techniques, with their p values being the Bayes posterior probability of no change between the 2004-2006 and 2006-2008 estimates. The "Total United States" estimates, along with the 95 percent confidence intervals (CIs) and p values, are based on design-based (direct) estimation methods. Note that the 2004-2006 CIs included in these tables for the "Total United States" row are design-based CIs rather than model-based CIs published in prior 2004-2006 substate tables.
a Difference between the 2004-2006 estimate and the 2006-2008 estimate is statistically significant at the 0.05 level.
b Difference between the 2004-2006 estimate and the 2006-2008 estimate is statistically significant at the 0.10 level.
1 Names of some of the substate regions for this State have changed across the two time periods (2004-2006 vs. 2006-2008). For details, see the "2006-2008 National Survey on Drug Use and Health Substate Region Definitions" at http://www.samhsa.gov/data/NSDUH/substate2k08/toc.aspx.

-- Not available. These regions were not defined consistently across the two time periods (i.e., 2004-2006 and 2006-2008); hence, the 2004-2006 estimates and p values are not available for these regions. The definitions of the substate regions listed in this table are provided in the "2006-2008 National Survey on Drug Use and Health Substate Region Definitions" at http://www.samhsa.gov/data/NSDUH/substate2k08/toc.aspx.
NOTE: The 2006-2008 estimates may differ from previously published estimates due to updates in the region definitions (using the 2008-2010 substate region definitions) and updates to the data. For details, see the "2006-2008 National Survey on Drug Use and Health: Guide to Substate Tables and Summary of Small Area Estimation Methodology" at http://www.samhsa.gov/data/NSDUH/substate2k08/toc.aspx.
NOTE: Substate, State, and census region estimates, along with the 95 percent Bayesian confidence (credible) intervals, are based on a survey-weighted hierarchical Bayes estimation approach and are generated by Markov Chain Monte Carlo techniques, with their p values being the Bayes posterior probability of no change between the 2004-2006 and 2006-2008 estimates. The "Total United States" estimates, along with the 95 percent confidence intervals (CIs) and p values, are based on design-based (direct) estimation methods. Note that the 2004-2006 CIs included in these tables for the "Total United States" row are design-based CIs rather than model-based CIs published in prior 2004-2006 substate tables.
a Difference between the 2004-2006 estimate and the 2006-2008 estimate is statistically significant at the 0.05 level.
b Difference between the 2004-2006 estimate and the 2006-2008 estimate is statistically significant at the 0.10 level.
1 Names of some of the substate regions for this State have changed across the two time periods (2004-2006 vs. 2006-2008). For details, see the "2006-2008 National Survey on Drug Use and Health Substate Region Definitions" at http://www.samhsa.gov/data/NSDUH/substate2k08/toc.aspx.

-- Not available. These regions were not defined consistently across the two time periods (i.e., 2004-2006 and 2006-2008); hence, the 2004-2006 estimates and p values are not available for these regions. The definitions of the substate regions listed in this table are provided in the "2006-2008 National Survey on Drug Use and Health Substate Region Definitions" at http://www.samhsa.gov/data/NSDUH/substate2k08/toc.aspx.
NOTE: The 2006-2008 estimates may differ from previously published estimates due to updates in the region definitions (using the 2008-2010 substate region definitions) and updates to the data. For details, see the "2006-2008 National Survey on Drug Use and Health: Guide to Substate Tables and Summary of Small Area Estimation Methodology" at http://www.samhsa.gov/data/NSDUH/substate2k08/toc.aspx.
NOTE: Substate, State, and census region estimates, along with the 95 percent Bayesian confidence (credible) intervals, are based on a survey-weighted hierarchical Bayes estimation approach and are generated by Markov Chain Monte Carlo techniques, with their p values being the Bayes posterior probability of no change between the 2004-2006 and 2006-2008 estimates. The "Total United States" estimates, along with the 95 percent confidence intervals (CIs) and p values, are based on design-based (direct) estimation methods. Note that the 2004-2006 CIs included in these tables for the "Total United States" row are design-based CIs rather than model-based CIs published in prior 2004-2006 substate tables.
a Difference between the 2004-2006 estimate and the 2006-2008 estimate is statistically significant at the 0.05 level.
b Difference between the 2004-2006 estimate and the 2006-2008 estimate is statistically significant at the 0.10 level.
1 Names of some of the substate regions for this State have changed across the two time periods (2004-2006 vs. 2006-2008). For details, see the "2006-2008 National Survey on Drug Use and Health Substate Region Definitions" at http://www.samhsa.gov/data/NSDUH/substate2k08/toc.aspx.
