Substance Use During the COVID-19 Pandemic in the Americas: A Scoping Review

During the COVID-19 pandemic, substance use in the Americas was influenced by various factors, including social isolation, increased stress, and disruption of healthcare services. While the impacts varied across populations, the health crisis exacerbated challenges related to substance use, particularly in more vulnerable groups. This article aims to describe the pandemic's impact on substance use and substance use disorders in the Americas region.

We conducted a scoping review across 4 databases (Pubmed, Scielo, Lilacs, and Google Scholar) using a search paradigm based on the combination of several keywords related to substance use during the COVID-19 pandemic in the Americas.

Most studies were conducted at the beginning of the pandemic and carried out in the United States and Canada. A higher proportion of the general population decreased or showed no changes in cannabis consumption. On the other hand, for those who reported pre-pandemic substance use, consumption has increased as a strategy to cope with COVID-related stress, exacerbating preexisting problems. Patients with substance use disorders reduced their visits to treatment services and in-person medication visits declined significantly. In an attempt to reverse the distancing of patients from the services, there was an increase in take-home medication and telehealth services. Rates for opioid-related deaths and other substance overdose-related deaths increased during the pandemic, especially among racial/ethnic minorities.

The study concludes that the pandemic-intensified substance use among vulnerable populations, particularly individuals with pre-existing mental health conditions or a history of substance use disorders, while having a low impact on the general population. This divergence has contributed to widening health disparities.
