ABSTRACT
This study aims to describe changes in tobacco and alcohol consumption in France during the first COVID-19 lockdown in March 2020 and its gradual lifting in May. The associated factors and the reasons reported explaining those changes are also studied. Data came from five waves of the CoviPrev online cross-sectional survey (approximately n = 2000 per wave) and the ViQuoP qualitative survey (n = 60), which took place between April and June. Most people self-reported stable consumption compared to before the lockdown, but 27% to 32% of smokers and 10% to 16% of drinkers had increased their consumption, depending on the wave of the survey. Boredom, stress and the search for pleasure were the main reasons reported. While the sociodemographic factors associated with an increase in tobacco and alcohol use differed according to the product and month, poor mental health was associated with an increase in both products in April and May. Between 10% and 19% of smokers and 22% to 25% of drinkers reported having reduced their consumption for their health or through constraints. The measures taken to manage the spring 2020 epidemic appear to have had contrasting impacts on tobacco and alcohol consumption in France. People whose lifestyles and mental health was most affected appear to have modified their consumption more frequently.
