Special Issue Information

Dear Colleagues,

Polysubstance use is prevalent among adolescents and young adults. In particular, alcohol, cannabis, and nicotine are the most commonly used substances by youth, which necessitates an understanding of the effects of their co-use and simultaneous use on brain structure, function, cognition, and health. Many studies have focused on the use of single substances on the brain, neurocognitive functioning, and health, but these studies may be less generalizable to the actual use characteristics of adolescents and young adults who more often engage in the use of multiple substances. Importantly, it is critical to understand whether the combination of different substances (e.g., alcohol and cannabis, cannabis and nicotine) has distinct effects on adolescents and young adults than the use of individual substances. The purpose of this Special Issue is to bring attention to recent research that has focused on the effects of alcohol, cannabis, nicotine, and other substance co-use on brain, behavior, and health outcomes, in an effort to better understand the effects of polysubstance use during a period of development characterized by protracted brain maturation. Papers on any combination of substance co-use are welcome, particularly original research articles, narrative reviews, systematic reviews, and meta-analyses that address this topic.

You may choose our Joint Special Issue in Behavioral Sciences.

Co-use of alcohol and cannabis is common among young adults in the United States. A behavioral economics framework indicates that greater engagement in substance-free sources of reinforcement may be protective against co-use frequency. The current study tested the association between proportionate alcohol-free reinforcement and the frequency of co-use among college freshmen. Participants (N = 86) were freshmen who enrolled in a freshman orientation course and completed surveys at the beginning of the semester. Past month alcohol use, cannabis use, and reinforcement from alcohol-free and alcohol-involved activities were assessed. A zero-inflated Poisson regression was used to test the association between proportionate alcohol-free reinforcement and days of co-use. The results indicated that proportionate alcohol-free reinforcement was negatively associated with co-use days in the count model when controlling for alcohol use days and gender as covariates (β: −3.28, p = 0.016). Proportionate alcohol-free reinforcement did not significantly differentiate individuals who did not engage in co-use in the zero-inflated model (β: −1.68, p = 0.497). The study suggested that greater proportionate alcohol-free reinforcement may be associated with lower engagement in the co-use of alcohol and cannabis among young adults. Increasing engagement in alcohol-free sources of reinforcement may be considered a target for co-use prevention or harm reduction efforts. Full article
