Associations Between Cannabis Messaging and Derived Psychoactive Cannabis Product Perceptions, Use, and Use Intentions Among a Sample of US Young Adults

This is the authors' abstract. We don't add key points for this paper.

Background Since the 2018 Agricultural Improvement Act, derived intoxicating cannabis products (DICPs) emerged as largely unregulated products; meanwhile, traditional cannabis use has increased. To inform effective prevention, research is needed to assess differences in motives for using cannabis only versus both cannabis and DICPs, as well as use-related consequences.Methods We analyzed survey data (June–November 2023) from 4,031 US young adults ages 18–34 (average age = 26.9; 63.9% White; 59.0% female; aiming for ∼50% past-month cannabis use). The analytic sample included participants reporting past-month cannabis use (n = 1,968). Two cross-sectional mediation models were conducted to examine: 1) cannabis use motives (social/cognitive enhancement and coping) in relation to use-related consequences (psychophysiological and sociobehavioral) via use category (cannabis-only vs. cannabis-DICP co-use) and 2) consequences in relation to use category via use motives.Results Overall, 54.4% reported cannabis-only use and 45.6% reported cannabis-DICP co-use. Greater enhancement and coping motives were associated with cannabis-DICP co-use (vs. cannabis-only use). Regarding Model #1, lower cannabis coping motives and cannabis-DICP use (vs. cannabis-only use) were associated with greater psychophysiological and sociobehavioral consequences, and the associations between coping and enhancement motives and psychophysiological and sociobehavioral consequences were indirectly mediated via cannabis-DICP co-use. For Model #2, lower psychophysiological and greater sociobehavioral consequences were associated with greater coping and enhancement motives, greater sociobehavioral consequences was associated with higher odds of cannabis-DICP co-use (vs. cannabis-only use), and psychophysiological and sociobehavioral consequences were indirectly associated with cannabis-DICP co-use through enhancement and coping motives.Conclusions Considering the risks associated with cannabis and DICP use, future intervention and prevention efforts should focus on the observed associations to reduce risk.
