Understanding Changes in Social Cannabis Use among Young Adults During the COVID-19 Pandemic: A Social Network Analysis

Abstract

Introduction. As the COVID-19 pandemic has caused historic morbidity and mortality and disrupted young people’s social relationships, little is known regarding change in young adults’ social cannabis use following social distancing orders, or other factors associated with such changes before and during the pandemic. Methods. 108 young adult cannabis users in Los Angeles reported on their personal (egocentric) social network characteristics, cannabis use, and pandemic-related variables before (July 2019 – March 2020) and during the COVID-19 pandemic (August 2020 – August 2021). Multinomial logistic regression identified factors associated with increasing or maintaining the number of network members (alters) participants used cannabis with before and during the pandemic. Multilevel modeling identified ego- and alter-level factors associated with dyadic cannabis use between each ego and alter during the pandemic. Results. Most participants (61%) decreased the number of alters they used cannabis with, 14% maintained, and 25% increased. Larger networks were associated with a lower risk of increasing (vs. decreasing); more supportive cannabis-using alters was associated with a lower risk of maintaining (vs. decreasing); relationship duration was associated with a greater risk of maintaining and increasing (vs. decreasing). During the COVID-19 pandemic (August 2020 – August 2021), participants were more likely to use cannabis with alters they also used alcohol with and alters who were perceived to have more positive attitudes towards cannabis. Conclusions. The present study identifies significant factors associated with changes in young adults’ social cannabis use following pandemic-related social distancing. These findings may inform social network interventions for young adults who use cannabis with their network members amid such social restrictions.

Cannabis Use Behaviors and Related Harms among Adults in Thailand by Sex Assigned at Birth and Age Groups

“…Working-aged and elderly female participants were more likely to report using cannabis for other non-medical purposes than the other groups. Recreational use of cannabis is known to be a negative coping mechanism against stress [23][24][25] ; however, it can also be social and not stress-related 26 . In this study, the "other purposes" category was meant to be inclusive and non-specific; thus, caveats are required with regard to this non-specificity.…”

Correlates of Cannabis Use and Self-Control Across a Diverse Sample of College Students: 2020-2022

“…In addition to self-control, social influence is a significant correlate of cannabis use in college students as well ( Bierhoff et al, 2019 ). The most common way cannabis is consumed among college students is small groups of friends sharing cannabis use devices ( DiGuiseppi et al, 2022 ). Whereas college students tend to use cannabis at much higher rates, they tend to experience fewer negative consequences directly related to their use compared to older adults ( Prince & Conner, 2019 ).…”

“…This decrease in use may be explained by the lack of social opportunities and limited access to cannabis, and parental involvement preventing cannabis use at home ( Merrill et al, 2022 ). However, many college age individuals continued engaging in social activities despite the recommendations, leading to an increase in social cannabis use with close friends during the pandemic ( DiGuiseppi et al, 2022 ).…”
