Real-world simultaneous alcohol and cannabis use: An ecological study of situational motives and social and physical contexts.
Conclusions: The combination of alcohol and cannabis use occurs during social situations and when motivated by positive reinforcement but number of cannabis uses is not increased when consuming cannabis with alcohol in social situations. Characterizing the complex interplay of situational factors that contribute to risky use will inform interventions.

Qualitative examination of simultaneous alcohol and cannabis use reasons, evaluations, and patterns among heavy drinking young adults.
Use of alcohol and cannabis together so their effects overlap (simultaneous use) is common among college students and associated with numerous negative consequences. The aim of this study was to gain insight into college students’ recent simultaneous use events in order to inform future studies (i.e., generate hypotheses, inform measures/assessments of simultaneous use, and identify factors influencing simultaneous use). Qualitative interviews of simultaneous use experiences among heavy drinking college students (n = 38) were conducted to better understand reasons for simultaneous use, evaluations of simultaneous use eve...

Examining replicability in addictions research: How to assess and ways forward.
Conclusions: We recommend researchers focus on effect sizes and use meta-analysis to evaluate the level of replicability. We also encourage direct replication attempts and sharing of data and code to facilitate direct replication.

Prevalence of medical and nonmedical cannabis use among veterans in primary care.
Conclusions: Veterans enrolled in VHA in states with legalized cannabis may be particularly likely to use cannabis. Veterans identifying as recreational users may be at increased risk for adverse clinical outcomes compared to medical-only users. Prevalence monitoring, assessment, and intervention services should be considered, particularly in states with legalized cannabis.

Trajectories of motivation and self-efficacy during a smoking quit attempt: An ecological momentary assessment study.
Conclusions: These findings highlight the need to incorporate dynamic measures of motivation in smoking research. Furthermore, the results underscore the value of utilizing EMA methods and trajectory parameters to gain a more nuanced understanding of the dynamic effects that key mechanisms have on smoking during a quit attempt.

Effect of alcohol, tobacco, and cannabis co-use on gray matter volume in heavy drinkers.
Conclusion: The additive effect of tobacco co-use on gray matter volumes in heavy drinkers was limited and localized. The effect of tri-use of alcohol, tobacco, and cannabis may have interacted, such that overlapping cannabis and tobacco use masked volume differences present in separate co-using groups.

Racial discrimination, depressive symptoms, ethnic–racial identity, and alcohol use among Black American college students.
Conclusions: Racial discrimination experiences put Black American young adults at risk for alcohol use and related problems through increased depressive symptoms. Ethnic–racial identity may buffer or exacerbate these associations depending on the specific dimension. The findings imply the need to target depressive symptoms and alcohol use simultaneously to promote health and well-being among Black Americans.

Young adult birthday celebrations as windows of risk for alcohol and cannabis use: 21st birthdays compared to other young adult birthdays.
Conclusions: 21st birthday celebrations represent a high-risk drinking event for young adults in general, and the current findings suggest event-specific prevention programs targeting all young adults turning 21 are warranted. Unlike alcohol where turning 21 is associated with socially and culturally normative use, a similar 21st birthday effect was not found for cannabis.

Racially invariant stimuli may bias outcomes in assessment of emotion processing.
Conclusion: Taken together, these preliminary findings do not reflect a deficit among Black respondents. Instead, our results reflect the need for greater attention to stimulus diversity and sensitivity to respondent demographics in emotion-processing examinations. Given the purported role of emotion processing in alcohol-related problems and the increase in racial minority representation in the U.S., elucidating these differences remains critical.

Longitudinal course of mental health symptoms among veterans with and without cannabis use disorder.
Objective: Cannabis use disorder (CUD) is the most common non-alcohol related substance use disorder (SUD) in the United States and is especially prevalent among returning veterans. The long-term mental health correlates of CUD remain unknown, which is significant given the rise in legalization and also recreational and medicinal cannabis use nationally. Method: Using a gender-balanced, national sample of 1,649 veterans (n = 115 with CUD; 75.2% White; M age = 37.49, SD = 9.88), we used latent growth curve modeling to examine posttraumatic stress disorder (PTSD) symptom severity, depressive symptoms, generalized anxiety, al...

Natural course of co-use of alcohol and cannabis in adolescents and young adults in Montréal, Canada.
We reported proportions of co-use, exclusive drinking (“drinking”), exclusive cannabis use (“cannabis use”), frequent co-use, frequent binge drinking, and frequent cannabis use by age and sex. Results: Co-use rose from 2% at age 12–13 to 23% at age 17, was stable at 44% at age 20 and 24, and then decreased to 37% at age 31. Drinking rose from 20% to 51%, and cannabis use was consistently rare ( (Source: Psychology of Addictive Behaviors)
