Tobacco consumption behavior change during the COVID-19 pandemic is associated with perceived COVID threat

Tobacco use is a risk factor for COVID-19 adverse outcomes. Despite health implications, data conflict regarding COVID-19 and tobacco consumption. We present results from a survey of health behaviors during the pandemic to identify how COVID-19 influenced tobacco use.

A national internet-based survey was deployed between May-September 2020. We analyzed participants who reported current or former smoking. We tabulated change in tobacco use, whether changes related to COVID-19, and measures of anxiety, depression, and novel perceived COVID-19 threat scale. We employed multinomial logistic regression to determine associations between these items and tobacco consumption.

We identified 500 respondents who reported ever smoking previously, 150 of which were currently smoking. Of 220 participants who reported any use of vapes, 110 were currently vaping. Increased perceived threat of COVID-19 was associated with both increased (aRR_increase 1.75, 95% CI [1.07-2.86], P = 0.03) and decreased (aRR_decrease 1.72 [1.04-2.85], P = 0.03) tobacco consumption relative to no change. There were no significant relationships found between perceived threat of COVID-19 and vaping behavior.

As perceived COVID-19 threat increased, people were more likely to increase or decrease their smoking than stay the same, even after controlling for anxiety and depression, both of which can affect smoking in either direction. Further study into motivators of increasing or decreasing affected tobacco consumption, and how barriers to care from safer-at-home policies and changes in care delivery moderate change in tobacco use will aid planning tobacco reduction interventions during the ongoing and future respiratory viral pandemics.
