OBJECTIVES: The aim of the study was to describe alcohol consumption and its changes in the Czech Republic during the period of governmental restrictions related to the COVID-19 pandemic. To this goal, an overview of the governmental measures that may have affected alcohol consumption was compiled from various sources (mostly media reports). METHODS: The paper analyses three surveys where the group from Charles University, Prague, participated in design and execution: the European Study Group on Alcohol use and COVID-19 (ESAC) convenience online survey that (in Czechia) took place at the onset of the COVID-19 pandemic in Europe, in April through June 2020 (n = 1,434), a computer-assisted web interviews (CAWI) survey carried out in November 2021 (n = 790), and another CAWI survey carried out in November 2022 (n = 1,738). These are complemented by a brief overview of official data on alcohol sales between 2019 and 2021 in Czechia from two sources, Ministry of Finance of the Czech Republic and the Nielsen IQ market research company. RESULTS: Changes in alcohol use appeared to be distributed among the population unequally, when the pandemic influenced different population groups in a different way. In all three surveys, the majority of respondents reported no change in their drinking frequency or quantity. Decreases in alcohol use were more prevalent than increases. Most pronounced changes were detected in at-risk drinkers, who have increased their alcohol use. Official revenue data suggest a small reduction in total alcohol sales in 2019-2021. CONCLUSIONS: Our research results do not support the hypothesis that substantial and unexpected social and economic changes caused by the COVID-19 pandemic, along with corresponding measures, acted as stressors that would have caused the majority of people in Czechia changing their behaviour related to alcohol use; however, high-risk users increased their consumption.

BACKGROUND: SARS-CoV-2 reached Europe in early 2020 and disrupted the private and public life of its citizens, with potential implications for substance use. The objective of this study was to describe possible changes in substance use in the first months of the SARS-CoV-2 pandemic in Europe. METHODS: Data were obtained from a cross-sectional online survey of 36,538 adult substance users from 21 European countries conducted between April 24 and July 22 of 2020. Self-perceived changes in substance use were measured by asking respondents whether their use had decreased (slightly or substantially), increased (slightly or substantially), or not changed during the past month. The survey covered alcohol (frequency, quantity, and heavy episodic drinking occasions), tobacco, cannabis, and other illicit drug use. Sample weighted data were descriptively analysed and compared across substances. RESULTS: Across all countries, use of all substances remained unchanged for around half of the respondents, while the remainder reported either a decrease or increase in their substance use. For alcohol use, overall, a larger proportion of respondents indicated a decrease than those reporting an increase. In contrast, more respondents reported increases in their tobacco and cannabis use during the previous month compared to those reporting decreased use. No distinct direction of change was reported for other substance use. CONCLUSIONS: Our findings suggest changes in use of alcohol, tobacco and cannabis during the initial months of the pandemic in several European countries. This study offers initial insights into changes in substance use. Other data sources, such as sales statistics, should be used to corroborate these preliminary findings.
