Table C.5 Average Annual Rate of First Use of Marijuana, by Age Group and State: 2004-2005 and 2005-2006 NSDUHs
State 12 or Older AGE GROUP (Years)
12-17 18-25 26 or Older
2004-2005 2005-2006 p value 2004-2005 2005-2006 p value 2004-2005 2005-2006 p value 2004-2005 2005-2006 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 2005-2006 estimate and the 2004-2005 estimate is statistically significant at the 0.05 level.
b Difference between the 2005-2006 estimate and the 2004-2005 estimate is statistically significant at the 0.10 level.
