Among the total sample, past year non-daily cannabis use varied significantly between 2002 and 2012 χ2(10, N = 614,579) = 6.25, p<0.001, but did not change significantly when comparing the years 2002 and 2012 directly (9.7% vs. 10.2%, respectively) χ2(1, N = 109,347) = 2.59, p=0.110 (Table 4a). Non-daily cannabis use varied for Whites overall χ2(10, N = 391,745) = 4.10, p<0.001, all age subgroups among Whites, as well as among Hispanics overall χ2(10, N = 94,578) = 4.14, p<0.001.
