      | Note: s=.05; any inconsistency between the 2000�2001 change estimate and 
        the respective prevalence estimates is due to rounding. 1Answer alternatives 
        were: (1) no risk, (2) slight risk, (3) moderate risk, (4) great risk, 
        and (5) can't say, drug unfamiliar.
 2Beginning in 1997, 
        data based on two-thirds of N indicated due to changes in questionnaire 
        forms.
