Trait mindfulness and cannabis use–related factors in adolescents and young adults with frequent use

Abstract

Background: Mindfulness-based interventions (MBIs) are effective in adult substance-use treatment and may be helpful for adolescents and young adults (AYAs). One target of MBIs is to improve trait mindfulness, which has been associated with better lifestyle and health outcomes. To inform MBIs for reducing cannabis use in AYAs, we sought to identify how trait mindfulness was associated with cannabis-related problems and quit attempts, as well as with motivation to change use in youth who report frequent use. Methods: Participants aged 15–24 years using cannabis ≥ 3x/week were recruited from AYA clinics in a northeastern US city to participate in a cannabis-use intervention pilot, randomized trial. At baseline, we assessed cannabis-use history, problems associated with use, attempts to quit, and trait mindfulness. All participants were offered two sessions of motivational enhancement therapy, during which they rated motivation to quit cannabis. Regression analyses were conducted to assess associations between trait mindfulness and cannabis use–related problems, attempts to quit, and motivation to change. Results: Seventy participants, mean age 20.7 ± 1.9 years, enrolled. Sixty percent identified as female, 47% as Black non-Hispanic, and 31% as Hispanic. Participants started using cannabis at mean age 15.0 ± 2.8 years and were using ≥ 3x/week by 17.0 ± 2.3 years. Higher mindfulness scores were associated with fewer cannabis-related problems (p = 0.004) and fewer quit attempts (p = 0.035). The number of cannabis-related problems did not significantly mediate the relationship between mindfulness and quit attempts. Trait mindfulness did not predict motivation to change cannabis use. Conclusions: Among AYAs using cannabis frequently, higher trait mindfulness was associated with both fewer cannabis use-–related problems and fewer quit attempts. Future research should assess whether trait mindfulness is an appropriate target for decreasing cannabis use and the utility of MBIs for reducing cannabis-use behaviors.
