Substance use and related harms in the context of COVID-19: a conceptual model. / Consommation de substances et méfaits connexes dans le contexte de la COVID-19 : un modèle conceptuel.

ABSTRACT

As the effects of COVID-19 have been unfolding, growing attention has been paid to the intersection of COVID-19 and substance use and the related harms. However, there are few theories and little empirical evidence to guide investigations in this area. To advance this emerging area of inquiry, we present a conceptual model that synthesizes evidence, information and knowledge on substance use and related harms in the context of the pandemic. The conceptual model offers a visual representation of the connections between the pandemic and substance use and related harms, and can be used to identify areas for future research.

As of June 2020, substance use and related harms in the context of a pandemic remained largely uninvestigated. The COVID-19 pandemic may impact how Canadians use substances and may present specific challenges and harms among people who use substances. The conceptual model in this paper offers a synthesis of evidence, information and knowledge of the concepts and associations relevant to substance use and harms in the context of the pandemic. Relevant concepts were synthesized into five interrelated domains that can be used to identify areas for future research into substance use and related harms in the context of COVID-19 substance use as a means of coping; changes in social support and networks; availability and accessibility of services; increased risk of COVID-19 transmission among people who use substances; and increased risk of severe outcomes.
