Note: CTL means control (n = 89); CD, cannabis dependent (n = 89); REC, recreational cannabis users (n = 87); all other = all remaining participants in the HCP (n = 941). CTL and CD are the only 2 groups that are matched, so the 2-sample t-test is reported only for the comparison between these 2 groups. Note that the CTL group is well matched on all variables except for tobacco usage; therefore, tobacco usage was used as a confound regressor in the primary analyses. The externalizing problems, antisocial behaviors, and rule-breaking behaviors are reported as age- and gender-adjusted percentile scores; the childhood conduct problems are scored as part of the SSAGA.
