Associations of alcohol, marijuana, and polysubstance use with non-adherence to COVID-19 public health guidelines in a US sample.

Background: We sought to understand the association between heavy alcohol and frequent drug use and non-adherence to recommended social distancing and personal hygiene guidelines for preventing the spread of COVID-19 early in the US pandemic. Methods: A survey was offered on the crowdsourcing platform, Amazon Mechanical Turk (MTurk) during April 2020 (the early days of strict, social distancing restrictions). The study included 1,521 adults ages 18 years and older who resided in the US and were enrolled as MTurk workers, i.e., workers who are qualified by Amazon to complete a range of human interaction tasks, including surveys through the MTurk worker platform. Main predictors included measures of heavy drinking, marijuana, and polysubstance use. The dependent measures were measures of social distancing and personal hygiene, based on guidelines recommended at the time of the survey by the US Centers for Disease Control to prevent the spread of COVID-19. Results: We found consistent negative associations between heavy drinking and drug use and adherence to social distancing and personal hygiene. Additionally, three control variables, age, gender, and race/ethnicity, were significant correlates of adherence to these measures. Conclusions: The findings here are consistent with previous research exploring links between substance use and other adverse health behaviors. Further, the negative association between heavy drinking (five or more drinks in one sitting) and adherence underscore the public health risks entailed with the unrestricted reopening of public drinking establishments.

Coronavirus disease 2019 crisis and intentional injuries: now is not the time to erode alcohol control policies.

In Canada, and elsewhere, the coronavirus disease 2019 (COVID-19) crisis has resulted in a social, economic, and alcohol policy environment that is likely to contribute to a rise in intentional injuries, whether interpersonal or self-directed violence. Heavy drinking has been identified as an important risk factor for intentional injuries, and with the erosion of alcohol control policies on alcohol availability, heavy drinking is likely to increase. During a time of social isolation, economic loss, psychological distress, and reduced access to health services and support networks, all of which are catalytic factors for both intentional injuries and heavy alcohol use, what is needed is individualized and population-based preventive interventions aimed at reducing alcohol consumption, rather than decisions to increase certain forms of alcohol availability.
