Perceived great risk of regular cannabis use varied significantly among women who were past year non-daily cannabis users between 2002–2012 χ2(10, N = 42,789) = 10.47, p<0.001, and when comparing the prevalence of perceived great risk in the years 2002 and 2012 directly, the prevalence decreased significantly (13.8% vs. 7.3%) χ2(1, N = 8,049) = 34.65, p<0.001 (Supplemental Table 3b6). Significant variations in perceived great risk were also observed among women of White, Black, and Hispanic race/ethnicities, with variation being observed among various race/ethnicity-age subgroups.
