“…This study contributes to the limited research examining associations of social context with various adverse outcomes. Prior investigations have primarily assessed undergraduates , limiting generalisability. Our study involved a relatively large, demographically‐diverse, community‐recruited sample.…”

“…Moreover, the context of participants’ most recent cannabis‐using occasion was not necessarily representative of the context of their typical cannabis use, potentially supressing the actual degree of relation between social context and our outcomes. Measuring social context through ecological momentary assessments could address this limitation . While we did assess cannabis use frequency, no standardised information was collected regarding cannabis dose.…”

“…Less is known about how social context of use impacts various cannabis‐related outcomes. Although solitary cannabis use has been associated with cannabis use disorder symptoms in adolescents and predicts drug‐related problems in adulthood , another study indicated that cannabis‐dependent individuals were more likely to use cannabis with others versus alone. It has been theorised that solitary substance use is risky because it does not allow individuals to compare their use to their peers’ use .…”

Introduction and Aims Given the increase in cannabis availability and use in North America, identification of risk factors for cannabis use and dependence is paramount. One factor that may be associated with various cannabis‐related adverse outcomes is the context in which it is used. This secondary analysis study sought to examine the extent to which the social context of cannabis use is related to patterns of use and associated harms. Design and Methods One hundred and eighty‐eight adult cannabis users were community‐recruited in Halifax, Canada. Participants took part in a face‐to‐face structured interview where they provided information about the social context of their most recent cannabis‐using occasion and about their patterns of, and motives for, cannabis use. Results Compared to individuals reporting their most recent cannabis‐using occasion as social, solitary users (n = 55) were significantly more likely to screen positive for psychosis, endorse more symptoms of cannabis abuse/dependence, report using cannabis to cope, and use cannabis on more days within the previous 30 days. On the other hand, social users were significantly more likely to report using alcohol in addition to cannabis during their most recent cannabis‐using occasion (all P < 0.05). Discussion and Conclusions Results suggest that solitary cannabis use may be associated with specific motives for use and future adverse consequences. Findings from this study serve as a guide for future investigations which could ultimately inform public policy and the development of targeted harm‐reduction strategies.

“…In the specific case of simultaneous marijuana and alcohol use, this would allow for clear isolation of the intention to use both drugs at the same time. These event-based EMA designs are also ideal in the assessment of social and environmental context of substance use, which may differ considerably by drug (e.g., Testa et al, in press; Lipperman-Kreda, Paschall, Saltz, & Morrison, 2017; Phillips, Phillips, Lalonde, & Prince, 2018). Given our findings that marijuana use high is positively associated with interpersonal conflict several hours later, future simultaneous use research should also consider that modes of marijuana administration with longer lasting and/or increased concentration of THC/CBD (e.g., edibles, dabs).…”

Alcohol and Marijuana use in Undergraduate Males: Between- and Within-Person Associations with Interpersonal Conflict

2018

Background: Among college students, interpersonal conflict with others is a common, yet stressful negative interpersonal experience. Research suggests that drinking episodes may contribute to the occurrence of conflict. Marijuana use, independently or in conjunction with alcohol, may also influence the likelihood of subsequent conflict. Objectives: We considered the temporal effects of independent and simultaneous alcohol and marijuana use episodes on the occurrence of interpersonal conflict. Use of multilevel modeling allowed us to distinguish the within-person effects of substance use from between-person differences in frequency of use. Methods: Within a sample of 427 college freshman males over 56 days of daily reports, we examined the independent and interactive effects of episodes of alcohol and marijuana on the odds of conflict within the next 1-, 2-, 3-, and 4 hours. Results: Multilevel modeling analyses showed that drinking episodes increased the likelihood of conflict occurring within the next 1, 2, 3, and 4 hours. Marijuana had weaker positive effects, significant only within the 2 hour window. There were no alcohol by marijuana interaction effects in any analysis. Conclusions/Importance: Both marijuana and alcohol independently increased the likelihood of interpersonal conflict; however, the marijuana effect appeared less robust. As marijuana use becomes more normative and accessible for college students, it is important to understand the extent to which marijuana use results in negative consequences and the contexts under which these effects unfold.

“…Alcohol use is also more likely to occur with others vs. being alone, and both at home and in social situations outside the home (e.g., bars, friend's house; Labhart et al, 2013;Simmons et al, 2005). Similarly, Phillips et al (2018) reported that cannabis use is more likely to occur when participants were with others compared to being alone. In addition to these daily contexts, college-based socially relevant events, such as home football games, have been associated with increased alcohol consumption (Glassman et al, 2010), and high-profile games were among the heaviest drinking days of the year (Neal & Fromme, 2007).…”
