NOTE: p value: Bayes posterior probability of no change.
NOTE: Illicit Drugs include marijuana/hashish, cocaine (including crack), heroin, hallucinogens, inhalants, or prescription-type psychotherapeutics used nonmedically; these estimates are based on data from original questions, excluding those on the use of over-the-counter drugs or new methamphetamine items that were 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: Estimates are based on a survey-weighted hierarchical Bayes estimation approach.
a Difference between the 2007-2008 estimate and the 2006-2007 estimate is statistically significant at the 0.05 level.
b Difference between the 2007-2008 estimate and the 2006-2007 estimate is statistically significant at the 0.10 level.

NOTE: p value: Bayes posterior probability of no change.
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 2007-2008 estimate and the 2006-2007 estimate is statistically significant at the 0.05 level.
b Difference between the 2007-2008 estimate and the 2006-2007 estimate is statistically significant at the 0.10 level.

NOTE: p value: Bayes posterior probability of no change.
NOTE: Illicit Drugs Other Than Marijuana include cocaine (including crack), heroin, hallucinogens, inhalants, or prescription-type psychotherapeutics used nonmedically; these estimates are based on data from original questions, excluding those on the use of over-the-counter drugs or new methamphetamine items that were 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: Estimates are based on a survey-weighted hierarchical Bayes estimation approach.
a Difference between the 2007-2008 estimate and the 2006-2007 estimate is statistically significant at the 0.05 level.

NOTE: p value: Bayes posterior probability of no change.
NOTE: Estimates are based on a survey-weighted hierarchical Bayes estimation approach.
a Difference between the 2007-2008 estimate and the 2006-2007 estimate is statistically significant at the 0.05 level.
b Difference between the 2007-2008 estimate and the 2006-2007 estimate is statistically significant at the 0.10 level.

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.
NOTE: Estimates are based on a survey-weighted hierarchical Bayes estimation approach.
a Difference between the 2007-2008 estimate and the 2006-2007 estimate is statistically significant at the 0.05 level.
b Difference between the 2007-2008 estimate and the 2006-2007 estimate is statistically significant at the 0.10 level.

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], and mental health centers). Illicit Drugs include marijuana/hashish, cocaine (including crack), inhalants, hallucinogens, heroin, or prescription-type psychotherapeutics used nonmedically; these estimates are based on data from original questions, excluding those on the use of over-the-counter drugs or new methamphetamine items that were 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: Estimates are based on a survey-weighted hierarchical Bayes estimation approach.

NOTE: p value: Bayes posterior probability of no change.
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], and mental health centers).
NOTE: Estimates are based on a survey-weighted hierarchical Bayes estimation approach.
a Difference between the 2007-2008 estimate and the 2006-2007 estimate is statistically significant at the 0.05 level.
b Difference between the 2007-2008 estimate and the 2006-2007 estimate is statistically significant at the 0.10 level.

Table C.23 Having at Least One Major Depressive Episode in Past Year among Persons Aged 12 to 17, by State: 2006-2007 and 2007-2008 NSDUHs
State 2006-2007 2007-2008 p value
NOTE: p value: Bayes posterior probability of no change.
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. Because of question changes preceding the 2008 adult MDE module, MDE data from 2008 and 2007 for adults 18 or older are not comparable. Therefore, only estimates for youths aged 12 to 17 are shown for MDE. For details, see Section A.10 in Appendix A of this report.
NOTE: Estimates are based on a survey-weighted hierarchical Bayes estimation approach.
a Difference between the 2007-2008 estimate and the 2006-2007 estimate is statistically significant at the 0.05 level.
b Difference between the 2007-2008 estimate and the 2006-2007 estimate is statistically significant at the 0.10 level.
