Tables 1-3 show detailed results for separate regression analyses for three age groups. Figure 3 shows significant interactions from those regression analyses for adolescents (12-17 year olds; Row 1) and other adults (26+ years of age; Row 2). Figure 3.A shows that among adolescents (12-17 year olds) a significant state-by-year interaction was seen for great-risk of using marijuana 1-2 times per week and Table 1 shows a trend interaction (p=0.07) for past-year marijuana abuse/dependence prevalence. Among young adults (18-25 year olds; Table 2), none of the regression analyses produced a trend or significant state-by-year interaction. Among other adults (26 years of age and older; Table 3), the state-by-year interactions was significant for great-risk of using marijuana 1-2 times per week (see Figure 3.B) and trended toward significance (p=0.07) for fairly/very easy to obtain marijuana (see Table 3). Tables 1-3 also provided additional information. For example, Coloradans compared to those from NMMS had lower rates of perception of great risk to using marijuana regularly and higher rates of past-year marijuana use. Associations between outcome variables and demographic variables within age group are also presented.
