NOTE: 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 2004-2005 and the 2005-2006 estimates. The "Total U.S." estimates, along with the 95 percent confidence intervals and 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.

P Value
NOTE: The State and census region Bayesian confidence (credible) intervals presented above use a simultaneous solution for the First Use of Marijuana and Never Used Marijuana outcomes, which had age group-specific random effects that were allowed to be correlated across the two outcomes. The associated Markov Chain Monte Carlo chains were used to calculate the posterior variance. Their p values are the Bayes posterior probability of no change between the 2004-2005 and the 2005-2006 estimates. The "Total U.S." estimates, along with the 95 percent confidence intervals and 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: 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, 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 2004-2005 and the 2005-2006 estimates. The "Total U.S." estimates, along with the 95 percent confidence intervals and 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).

Table 12 – Tobacco Product Use in the Past Month among Persons Aged 18 or Older, by State: Percentages, Annual Averages, and P Values from Tests of Differences between Percentages, 2004-2005 and 2005-2006 NSDUHs
State 2004-2005
(Estimate)
2004-2005
(95% Confidence Interval)
2005-2006
(Estimate)
2005-2006
(95% Confidence Interval)
P Value
NOTE: 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 2004-2005 and the 2005-2006 estimates. The "Total U.S." estimates, along with the 95 percent confidence intervals and 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: Tobacco Products include cigarettes, smokeless tobacco (i.e., chewing tobacco or snuff), cigars, or pipe tobacco.
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, 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 2004-2005 and the 2005-2006 estimates. The "Total U.S." estimates, along with the 95 percent confidence intervals and 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.

P Value
NOTE: 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 2004-2005 and the 2005-2006 estimates. The "Total U.S." estimates, along with the 95 percent confidence intervals and 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).
a Difference between the 2004-2005 estimate and the 2005-2006 estimate is statistically significant at the 0.05 level.

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).
