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 2010-2011 and the 2011-2012 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: 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.

Table 5 – First Use of Marijuana among Persons Aged 18 or Older, by State: Average Annual Rates Based on 2010, 2011, and 2012 NSDUHs
State 2010-2011
(Estimate)
2010-2011
(95% Confidence Interval)
2011-2012
(Estimate)
2011-2012
(95% Confidence Interval)
P Value
NOTE: 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 2010-2011 and the 2011-2012 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: 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 2010-2011 estimate and the 2011-2012 estimate is statistically significant at the 0.05 level.
b Difference between the 2010-2011 estimate and the 2011-2012 estimate is statistically significant at the 0.10 level.

The "Total U.S." estimates, along with the 95 percent confidence intervals and p values, are based on design-based (direct) estimation methods.

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 2010-2011 and the 2011-2012 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: Tobacco Products include cigarettes, smokeless tobacco (i.e., chewing tobacco or snuff), cigars, or pipe tobacco.
a Difference between the 2010-2011 estimate and the 2011-2012 estimate is statistically significant at the 0.05 level.
b Difference between the 2010-2011 estimate and the 2011-2012 estimate is statistically significant at the 0.10 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 2010-2011 and the 2011-2012 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: 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 2010-2011 estimate and the 2011-2012 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 2010-2011 and the 2011-2012 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: 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).

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 2010-2011 and the 2011-2012 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: Serious mental illness (SMI) is defined as having a diagnosable mental, behavioral, or emotional disorder, other than a developmental or substance use disorder, that met the criteria found in the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) and resulted in serious functional impairment. The 2010-2011 SMI estimates may differ from previously published estimates due to revised estimation procedures. 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/NSDUH/2k12State/NSDUHsae2012/Index.aspx.
