All 45 enrollees reported regular use of both cannabis and alcohol. These participants were grouped by use disorder according to their SCID interview diagnosis. Of the 45 enrollees, 17 participants met criteria for AUD and 28 did not. For CUD, 26 of the participants met criteria, while 19 did not meet criteria for CUD. Specifically, the subgroups consisted of 17 people currently meeting criteria for only CUD, eight currently meeting criteria for only AUD, nine meeting criteria for both AUD and CUD, and 11 not meeting criteria for any substance use disorder. The groups contained a mix of individuals who were diagnosed with mild, moderate, or severe use disorder(s), but all were diagnosed based on use within the past 12 months. Other substance use disorders were assessed on the SCID interview, and six participants had additional other substance use disorder diagnoses. The four groups were comparable in age and race (Table 1), but were notably unbalanced on sex and this was accounted for statistically. All groups had an average Beck depression total score under 10, which is considered normal35.Table 1Participant
