continued to escalate during the follow-up period and remained elevated at the final assessment, that we termed the “high” use class (n=186); and (c) a class that included escalating use that involved similar high use at baseline but a less steep increase in use during the follow-up, that we termed the “moderate” use class (N = 137). Also, as shown in Table 1, those in the high and the moderate use trajectories were significantly more likely to be male, have used cannabis at an earlier age, and meet criteria for a lifetime history of cannabis use disorder (CUD) as well as conduct disorder.
