Correlates of Cannabis Use and Self-Control Across a Diverse Sample of College Students: 2020-2022.

Abstract

Background: Despite the established relationship between substance use and self-control, it is unknown how the COVID-19 pandemic may have played a role in this association. Given the unique circumstances of the pandemic along with changing societal regulations surrounding cannabis use, and their collective impact on college students, there is a need to examine the relationship between cannabis and self-control during the pandemic era.

Methods: Data was collected from a repeated cross-sectional sample of college students at a mid-sized, urban U.S. institution during 2020-2022. Logistic and negative binominal regression analyses along with an ANCOVA were conducted to examine associations between self-control and past 30-day cannabis use.

Results: Lower self-control was significantly associated with using cannabis in the past 30-days with those individuals with self-reported low self-control using cannabis significantly more and more times per day. Finally, we found that both past 30-day cannabis use and cohort significantly predicted self-control with both individuals who report past 30-day cannabis use and the 2020 cohort reporting lower levels of self-control. There was not a significant interaction effect.

Conclusions: Despite evolving legislation regarding both medicinal and recreational cannabis use, colleges often maintain drug-free campus policies. Given high rates of cannabis use among college students and continued development of self-control, this association should be examined longitudinally and considered when creating college-level cannabis policies. Implications for college students surrounding COVID-era environments, and self-control are discussed.
