NOTE: p value: Bayes posterior probability of no change.
NOTE: Any Illicit Drug includes marijuana/hashish, cocaine (including crack), heroin, hallucinogens, inhalants, or any prescription-type psychotherapeutic used nonmedically.
NOTE: Estimates are based on a survey-weighted hierarchical Bayes estimation approach.
^a Difference between the 2000-2001 estimate and the 1999-2000 estimate is statistically significant at the 0.05 level.
^b Difference between the 2000-2001 estimate and the 1999-2000 estimate is statistically significant at the 0.10 level.
¹ This estimate is the weighted average of the hierarchical Bayes estimates across all States and the District of Columbia and typically is not equal to the direct sample-weighted estimate for the Nation.

NOTE: p value: Bayes posterior probability of no change.
NOTE: Average Annual 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 2000-2001 estimate and the 1999-2000 estimate is statistically significant at the 0.05 level.
^b Difference between the 2000-2001 estimate and the 1999-2000 estimate is statistically significant at the 0.10 level.

NOTE: p value: Bayes posterior probability of no change.
NOTE: Any Illicit Drug Other Than Marijuana includes cocaine (including crack), heroin, hallucinogens, inhalants, or any prescription-type psychotherapeutic used nonmedically.
NOTE: Estimates are based on a survey-weighted hierarchical Bayes estimation approach.
^a Difference between the 2000-2001 estimate and the 1999-2000 estimate is statistically significant at the 0.05 level.
^b Difference between the 2000-2001 estimate and the 1999-2000 estimate is statistically significant at the 0.10 level.
¹ This estimate is the weighted average of the hierarchical Bayes estimates across all States and the District of Columbia and typically is not equal to the direct sample-weighted estimate for the Nation.
