There was no evidence for differences in magnitude of associations between race/ethnicity and marijuana across time for males. Among females, the difference in the magnitude of association between race/ethnicity and any marijuana use (B=-0.63, SE=0.25, p=0.01) and at least weekly use (B=-0.97, SE=0.30, p<0.01) diminished over time (see Table 3), and frequency of use among users (B=-0.69, SE=0.32, p=0.03) crossed-over, whereby Black females had significantly higher frequency of use by Wave 4. Convergence was also documented for at least weekly use (B=-0.97, SE=0.30, p<0.01, see Online Table 3).
