State Total AGE GROUP (Years)
12-17 18-25 26 or Older
2003-2004 2004-2005 p Value 2003-2004 2004-2005 p Value 2003-2004 2004-2005 p Value 2003-2004 2004-2005 p Value
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.
NOTE: Estimates are based on a survey-weighted hierarchical Bayes estimation approach.
a Difference between the 2004-2005 estimate and the 2003-2004 estimate is statistically significant at the 0.05 level.
b Difference between the 2004-2005 estimate and the 2003-2004 estimate is statistically significant at the 0.10 level.

Table C.5 Average Annual Rate of First Use of Marijuana, by Age Group and State: 2003-2004 and 2004-2005 NSDUHs
State Total AGE GROUP (Years)
12-17 18-25 26 or Older
2003-2004 2004-2005 p Value 2003-2004 2004-2005 p Value 2003-2004 2004-2005 p Value 2003-2004 2004-2005 p Value
NOTE: p value: Bayes posterior probability of no change.
NOTE: Average annual rate = 100*{[X1 ÷ (0.5 * X1 + X2) ] ÷ 2}, where
X1 is the number of marijuana initiates in 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 2003-2004 estimate is statistically significant at the 0.05 level.
b Difference between the 2004-2005 estimate and the 2003-2004 estimate is statistically significant at the 0.10 level.
