Linden-Carmichael AN, Stull SW, Lanza ST. Alcohol and cannabis use in daily lives of college-attending young adults: Does co-use correspond to greater reported pleasure? Addict Behav 2024; 159:108130. [PMID: 39178638 DOI: 10.1016/j.addbeh.2024.108130] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2024] [Revised: 07/23/2024] [Accepted: 08/12/2024] [Indexed: 08/26/2024]
Abstract
Co-use of alcohol and cannabis is prevalent and linked with heightened risk for substance-related harms. The current study investigated the role of substance-related pleasure as a reinforcing factor for co-use relative to alcohol or cannabis use. Specifically, we used data from a 21-day diary study of college students to examine day-level associations between co-use and self-reported substance-related pleasure (any, level of pleasure). Participants were 237 college students (65 % female sex at birth, ages 18-24) who reported 1+ alcohol and cannabis co-use occasion. Participants completed daily surveys across 21 consecutive days about yesterday's substance use and experiences of pleasure, yielding 2,086 daily surveys involving alcohol and/or cannabis use. Multilevel models indicated that odds of substance-related pleasure were higher on days with co-use relative to days with single-substance use, and level of pleasure was higher on co-use days relative to cannabis but not alcohol use days. Pleasure may serve as a reinforcing property of co-use that may be related to continued use despite experience of negative consequences. Intensity of pleasure related to co-use appears to be largely driven by use of alcohol. However, given mixed findings concerning level of pleasure, individuals may report co-use increases feelings of pleasure but do not actually experience more pleasure. Pleasure may serve as a viable target in future prevention and intervention programming targeting co-use.

Abstract
Emerging adult alcohol and cannabis co-use is on the rise and enacts risk for alcohol misuse/alcohol use disorder (AUD). However, few studies have differentiated whether levels of cannabis use (rather than any cannabis use) moderate between-person risk. Considering low-frequency co-users may use both substances via substitution, low-risk/frequency co-use may not enact the same risk for AUD as higher risk co-use. The present study sought to test this assertion. Public access data on emerging adults from the National Study on Drug Use and Health were used (2002-2019; N = 231,681). Participants reported on their past year alcohol use, cannabis use, as well as AUD symptoms. Regression models tested whether levels of cannabis use frequency moderated the association between alcohol use frequency and AUD symptom counts. A significant interaction of cannabis use frequency by alcohol use frequency predicting AUD symptoms was detected. Individuals who co-used alcohol and cannabis reported more AUD symptoms than those who only used alcohol at the same frequency or less. However, co-use was associated with lower AUD symptom counts than alcohol-only use at higher frequency. Findings suggest that all co-users (and alcohol-only users) are not necessarily created equal, and that relations among co-use and risk for AUD symptoms are complex. Rather than a dichotomy of co-users versus alcohol-only users, between-group risk may depend on frequency of both alcohol and cannabis use.

ALCOHOL, CLINICAL & EXPERIMENTAL RESEARCH 2023; 47:168-179. [PMID: 36480451 PMCID: PMC10275144 DOI: 10.1111/acer.14982] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Revised: 10/28/2022] [Accepted: 11/16/2022] [Indexed: 11/23/2022]
Abstract
BACKGROUND Alcohol and cannabis use are common among young adults and most young adults who use both substances have used them simultaneously (i.e., using both substances so their effects overlap). Because simultaneous use is associated with a greater number and severity of consequences than single substance use, research is needed to examine the decision-making process of engaging in this high-risk behavior. We conducted a qualitative examination of intentions (i.e., plans) and willingness (i.e., one's openness to engage in the behavior if an opportunity presents itself) to engage in simultaneous use from the perspective of young adults who frequently report this substance use behavior. METHODS We recruited 36 young adults who reported simultaneous use and heavy drinking (4+/5+ drinks for women/men; 64% women, ages 18 to 25) to participate in semi-structured interviews. All interviews were double coded for thematic analysis and both novel and a priori themes were found. RESULTS Young adults distinguished between intending to engage in simultaneous use and being willing to engage in simultaneous use. They reported that intentions and willingness varied from occasion to occasion. They also reported that context and alcohol consumption influenced their willingness to engage in simultaneous use. Peer pressure or offers increased their willingness to use cannabis while drinking and having current or next-day responsibilities decreased their willingness to engage in simultaneous use. Additionally, planned simultaneous use occasions were characterized as being special events where young adults consumed more substances, but were more likely to monitor their use than unplanned occasions. CONCLUSIONS Intentions and willingness may be important proximal predictors of simultaneous use of alcohol and cannabis. Building off this qualitative work, quantitative research should identify which factors influence the decision-making process to engage in simultaneous use and determine when intentions and willingness are most predictive of risky simultaneous use behavior.

Abstract
OBJECTIVE Disentangle the temporal relationships between frequency of cannabis use and alcohol consumption. METHODS A cross-lagged model providing standardised coefficients (SCs)±their standard errors in 13 255 men and 13 696 women enrolled in 2015 or 2016 in the French population-based 'CONSulTANts des Centres d'Examens de Santé' (CONSTANCES) cohort. Cannabis use was categorised as follows: 'No use during the past 12 months', 'Use during the past 12 months but not in the past month' and 'Use in the past month' for cannabis use at baseline, and No use during the past 12 months, 'Use less than once per month' and 'Use once per month or more' for cannabis use at 1 year of follow-up. Alcohol consumption was measured at baseline and at 1 year of follow-up and three categories were determined: low risk (<28 drinks per week in men; <14 drinks per week in women), moderate risk (≥28 and<42 in men; ≥14 and<28 in women) and high risk (≥42 in men; ≥28 in women). Analyses were adjusted for age, sex, education, income, tobacco consumption, self-rated health status and depressive symptoms. RESULTS Both associations from alcohol to cannabis and from cannabis to alcohol were significant (SC=0.02±0.01 with p=0.003 and SC=0.06±0.01 with p<0.001, respectively). However, the SC of the association from cannabis to alcohol was three times higher than the opposite association (p<0.001). After stratification for sex, SCs of the association from cannabis to alcohol were more than two times higher than for the opposite association in men, and more than four times higher in women (both p<0.001). CONCLUSIONS The association between frequency of cannabis use and subsequent alcohol consumption was stronger than the opposite association. This finding encourages considering the risk of increased alcohol consumption among cannabis users.

Abstract
Objective: Several studies suggest that alcohol and cannabis co-users are heavier drinkers and experience more alcohol-related consequences. However, day-level associations between co-use and drinking levels are mixed. One reason may be that individual characteristics moderate the daily impact of using alcohol alone or in conjunction with cannabis. The theory would suggest that highly impulsive individuals may drink more on co-use days, yet this assertion remains untested. Therefore, the current study tested whether impulsivity moderated the effect of co-use on same-day drinking quantity within veterans, a high-risk sample for substance use and impulsivity. Method: In a longitudinal observational study, co-using veterans (N = 139) completed three semi-annual assessments reporting on their daily drinking quantity and cannabis use via Timeline Followback (Observations = 19,245) and impulsivity via the UPPS-P. Mixed effect modeling was used to test hypotheses that co-use (compared to alcohol-only) days would be associated with heavier drinking for those high (but not low) in positive and negative urgency. Results: Significant interactions were found for positive urgency (PU) and lack of perseverance (LP), such that individuals at mean and low levels of PU and LP drank less on co-use (compared to alcohol-only) days. There were no significant interactions for other UPPS-P impulsivity facets. Conclusion: Findings are consistent with a substitution/compensatory effect for individuals at mean and low levels of both UPPS-P facets, and may be a byproduct of frequent cannabis use in veterans. In contrast, findings suggest that co-use and alcohol-only days may be characterized by similarly high levels of drinking for highly impulsive individuals.

Abstract
Objective: Simultaneous use of alcohol in combination with cannabis ("co-use") is common among young adults, and associated with myriad consequences. Yet no studies have examined how co-use may confer vulnerability for sexual assault (SA). Further, though both co-use and SA commonly occur in social settings, there have been no examinations of the role that co-use may play in the broader social context that leads to assault risk. This was the objective of the present study. Method: In a community sample of young adult women, (N = 174; Mage = 22.6), we examined risk pathways to SA, guided by Routine Activities Theory (Mustaine & Tewksbury, Criminal Justice Review, 2002, 27, 89). Using a longitudinal burst design with 27 daily assessments across 1 year, women reported on their own and others' alcohol, cannabis, and co-use, and on social context and assault experiences. Results: Multilevel path model results showed alcohol and cannabis co-use to confer unique risk for SA, above and beyond the influence of use of either substance alone. Intoxication and components of the co-use social context (proximity to offenders) mediated this risk. Importantly, we observed a key role for co-use by others within the social context in assault risk. Conclusions: This study adds to the literature by providing a nuanced and contextual account of how cannabis-alcohol co-use may lead to assault vulnerability in young adult women. Findings underscore the need for intervention efforts that expand their focus to include the broader social context, and the role that the use and co-use behaviors of others may play within this context.

Abstract
Substance abuse is a major and prevalent public health concern among university students. Tobacco smoking, risky alcohol behavior, and illegal drug consumption may lead to health problems and behavioral and academic issues. Several individual and environmental factors associate with substance abuse in this population, and the mediating effect of alcohol abuse in the relationship between tobacco smoking and drug consumption is yet to be explored. The purposes of this study were to evaluate the association of individual and environmental factors and substance use, and to analyze the relationship between tobacco smoking, alcohol abuse, and drug consumption, considering alcohol abuse as a possible mediator. A total of 550 Spanish undergraduate and postgraduate students completed several questionnaires regarding their smoking status, alcohol use, and drug consumption during the last six months. Bivariate and multivariate analyses were conducted to explore associations between factors. Direct, indirect and mediating effects were tested using a partial least squares approach (PLS-SEM). The results indicated that substance abuse is associated with being male, living with other students, and combined substance consumption. PLS-SEM showed a significant effect of tobacco smoking and alcohol abuse on drug consumption. Alcohol abuse plays a mediating role in the relationship between tobacco smoking and drug use.
