Abstract

This study presents nationally representative estimates of self-reported changes in alcohol and cannabis consumption since the onset of COVID-19 in Canada. We used data from the Survey on COVID-19 and Mental Health (collected from September to December 2020) to calculate the prevalence of self-reported change in alcohol and cannabis consumption. We found that 15.7% of respondents self-reported an increase in alcohol consumption and 5.4% in cannabis consumption since the start of the pandemic. Sociodemographic disparities were also observed, indicating that increased alcohol and cannabis consumption may be more prevalent among certain populations.

Cette étude présente des estimations représentatives à l’échelle nationale portant sur les changements autodéclarés relatifs à la consommation d’alcool et de cannabis depuis le début de la pandémie de COVID 19 au Canada. Nous nous sommes servi de données de l’Enquête sur la COVID 19 et la santé mentale (qui a eu lieu de septembre à décembre 2020) pour calculer la prévalence de ces changements. Les résultats révèlent que 15,7 % des répondants ont déclaré avoir augmenté leur consommation d’alcool et 5,4 % leur consommation de cannabis depuis le début de la pandémie. Des disparités sociodémographiques ont été observées, laissant supposer que l’augmentation de la consommation d’alcool et de cannabis serait plus répandue au sein de certaines populations.

Keywords: COVID-19; alcohol; alcohol use; cannabis; cannabis consumption.

Plain language summary

From 11 September to 4 December 2020, 15.7% and 5.4% of individuals self-reported an increase in alcohol and cannabis consumption, respectively, compared to before the pandemic. Individuals who reported that their mental health was worse now, compared to before the pandemic, had the highest prevalence of self-reported increase in alcohol and cannabis consumption. Understanding the social determinants of health is critical to the development of harm reduction and mitigation strategies.
