Cannabis Use and Sharing Practices Among Sexual Minority and Heterosexual Individuals During the COVID-19 Pandemic.

Purpose: Cannabis behaviors during the COVID-19 pandemic among sexual minority (SM) individuals in the United States remain understudied. This study assessed the prevalence and correlates of cannabis use and cannabis sharing, a potential risk for COVID-19 transmission, among SM and heterosexual-identified individuals in the United States during the COVID-19 pandemic. Methods: This cross-sectional study used data from an anonymous, US-based web survey on cannabis-related behaviors from August to September 2020. Included participants reported past-year nonmedical cannabis use. Associations between frequency of cannabis use and sharing behaviors by sexual orientation were evaluated using logistic regression analysis. Results: Overall, 1112 respondents reported past-year cannabis use; mean age 33 years (standard deviation = 9.4), 66% male identified ( n  = 723), and 31% SM identified adults ( n  = 340). Increased cannabis use during the pandemic was similar among SM (24.7%; n  = 84) and heterosexual (24.9%; n  = 187) respondents. Any sharing during the pandemic was 81% for SM adults ( n  = 237) and 73% for heterosexual adults ( n  = 486). In the fully adjusted models, the odds of daily/weekly cannabis use and the odds of any cannabis sharing among SM respondents were 0.56 (95% confidence interval [CI] = 0.42-0.74) and 1.60 (95% CI = 1.13-2.26), respectively, compared with heterosexual respondents. Conclusions: SM respondents were less likely to use cannabis with high frequency during the pandemic but more likely to share cannabis compared with heterosexual respondents. Sharing cannabis was high overall, which may increase COVID-19 risk. Public health messaging around sharing may be important during COVID-19 surges and respiratory pandemics especially as cannabis becomes more widely available in the United States.
