Social anxiety is often purported to be a risk factor for increased cannabis use. Cannabis use motives are strong explanatory predictors of cannabis use embedded within social contexts. This investigation explored the impact of social anxiety, cannabis motives, and their interaction on willingness to use cannabis in a community sample of emerging adults. Social anxiety was anticipated to positively correlate with coping and conformity motives and greater willingness to use cannabis in peer social contexts. Motives to use were hypothesized to potentiate social anxiety’s influence on cannabis use decision-making. In total, 124 participants completed an audio simulation of social cannabis use contexts (Can-SIDE) and standard measures of social anxiety (SIAS) and use motives (MMM). Contrary to expectations, social anxiety exerted a protective effect on willingness to use cannabis, but only when conformity, social, and expansion motives were at or below average. These effects varied by social contexts of use. Social anxiety leading to increased cannabis use may be most apparent in clinical samples and in high-risk cannabis users, but this pattern was not supported in this sample of community living emerging adults below clinical cutoffs for cannabis use disorder with relatively high social anxiety.

Purpose: Young adults experiencing chronic pain may self-medicate with cannabis. We examined perceived risks and benefits of cannabis use among young adult users by chronic pain status, and identified relationships among perceived risks and benefits, physical and mental health, and cannabis-related problems. Methods: Young adults reporting at least weekly cannabis use (N = 176, 50.9% with chronic pain) reported perceptions of lifetime risks and benefits associated with cannabis use, physical and mental health, and cannabis-related problems. Results: Young adults without chronic pain reported better physical and mental health than those with chronic pain. Cannabis use, problems, and risk and benefit perceptions did not differ by pain status. Risk and benefit perceptions were unrelated to physical health, perceiving fewer risks and more benefits was associated with better mental health, and perceiving more risk was associated with cannabis problems. Chronic pain status moderated the relationship between perceived benefits and outcomes, such that perceiving more benefits was associated with better physical health for those without chronic pain. Further, greater perceived benefits were associated with more cannabis-related problems for those without chronic pain but fewer problems for those with chronic pain. Conclusion: This study offers insight into the perceptions of risks and benefits among young adult cannabis users and associations with physical and mental health and cannabis-related problems. The effects of perceived benefits on physical health and cannabis-related problems differs for young adults with and without pain, suggesting assessment and consideration of pain status may be valuable in intervention contexts.

This study examined whether the content (alcohol vs. nonalcohol) and valence (positive vs. negative) of episodic future thinking (EFT) are associated with delay discounting (DD) and alcohol demand. Participants (N = 360) were college students (Mage = 21.64 years, 84.44% female, 76.11% White) reporting alcohol consumption in the past month recruited to participate in an online, cross-sectional study. Participants were randomly assigned to a control condition or one of four EFT cue-generation conditions (positive alcohol, negative alcohol, positive nonalcohol, and negative nonalcohol). Then participants in EFT conditions generated EFT cues based on the assigned condition. Afterward, all participants completed the DD task and alcohol purchase task; participants in the EFT conditions completed modified tasks during which their EFT cues were displayed. Finally, participants completed a self-report battery assessing alcohol consumption, alcohol-related problems, and demographics. Participants assigned to nonalcohol EFT conditions discounted future rewards significantly less than those in alcohol EFT conditions, F(1, 266) = 6.87, p = .009, ηp² = .025. However, there was no main effect of EFT valence on DD. EFT content around professional work, but not social relationships, was associated with less steep DD (β = -.24, p < .001). No effect of EFT on alcohol demand intensity was found. EFT effect on DD may lie in content rather than valence, in which alcohol-free EFT, whether positive or negative, was associated with preference for later but larger rewards. Incorporating a professional goal into imagined events might play a key role in EFT effects on promoting the valuation of future consequences.

Limited research has explored the role of in-session behavior during motivational enhancement (ME) in group formats. The current study presents initial feasibility of assessing behavior of high school students (N = 425) attending Project Options, a voluntary secondary drug and alcohol prevention program utilizing ME techniques. Building on previous research exploring client language supporting/opposing health behavior, student group behavior was coded live at the specific utterance and global level; group leader behavior was also coded globally. Interrater reliability of the coding system was assessed, and preliminary validity of the coding system was examined by exploring associations between characteristics of group members and in-session group behavior. Initial reliability estimates were excellent for the specific behavior codes. Reliability of the global codes was mixed, with raters demonstrating good reliability on support for unhealthy behavior, opposition to unhealthy behavior, and support for healthy behavior. Reliability of the group leader codes was fair to poor. Greater percent healthy talk was associated with a lower percentage of group members reporting lifetime alcohol use. The results of the current study suggest that some in-session behavior at the group level can be coded reliably via live observation and that in-session behavior at the group level is associated with alcohol use prior to attending the program. Future research is needed to explore the utility of in-session behavior in terms of predicting future behavior at the group and individual level.

Cannabis use is increasing among college students and commonly co-occurs with anxiety symptoms in this age group. Interventions that reduce anxiety may also reduce cannabis use. Behavioral economic theory suggests that substance use reductions are most likely when there is an increase in substance-free reinforcement. This randomized pilot trial evaluated the efficacy of a brief motivational intervention (BMI) for cannabis supplemented by either a substance-free activity session (SFAS) or a relaxation training (RT) session for reducing cannabis use, problems, craving, and anxiety symptoms. One hundred thirty-two college students (Mage = 19.9; 54% female; 67% White, 31% Black) who reported five or more past-month cannabis use days were randomized to: (a) assessment-only (AO); (b) BMI plus SFAS; or (c) BMI plus RT. Participants in the BMI conditions received two individual counselor-administered sessions plus a brief phone booster session. Outcomes were evaluated 1- and 6-months postintervention. Relative to assessment, both BMI + SFAS and BMI + RT were associated with significant reductions in cannabis problems and craving at 1-month follow-up, and significant reductions in anxiety at 6-month follow-up. Relative to AO, BMI + RT was associated with significant reductions in cannabis use at 1-month follow-up. There were no differences between BMI conditions. This pilot trial was not adequately powered to conclusively evaluate relative efficacy but provides preliminary support for the short-term efficacy of both two-session interventions for reducing anxiety and cannabis-related risk among nontreatment seeking emerging adults.
