NOTE: SIG=Significant difference between 2003-2004 and 2002-2003 percentages; ns=not significant   at the 0.05 level
NOTE: Average annual incidence rate = {(Number of marijuana initiates in past 24 months)/[(Number of marijuana initiates in past 24 months * 0.5) + Number of persons who never used marijuana]}/2. Both the computation components, Number of marijuana initiates in past 24 months and number of persons who never used marijuana, 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.
NOTE: Estimates are based on a survey-weighted hierarchical Bayes estimation approach.
a Difference between the 2003-2004 estimate and the 2002-2003 estimate is statistically significant at the 0.05 level.
b Difference between the 2003-2004 estimate and the 2002-2003 estimate is statistically significant at the 0.10 level.
