The spread of COVID-19 in Russia has led to restrictive measures. The stress associated therewith had a noticeable psychoemotional effect on the population, which could not but affect the numbers and patterns of acute chemical poisonings (ACP). This study aimed to investigate the patterns of ACP in Moscow in the context of the COVID-19 pandemic. We analyzed data describing cases admitted with ACP to N.V. Sklifosovsky Research Institute for Emergency Medicine in 2019–2021, factoring in the dynamics COVID-19 prevalence as diagnosed with RT-PCR tests. The results of the analysis were processed using nonparametric methods and GraphPad Prism 9 software. Within the considered period, 2020 was the peak year. The number of acute poisonings (AP) with ethanol and its surrogates in 2020 was 109.7% greater than in 2019 (both sexes; the figure for women alone was 286.2%). Male patients suffered AP with drugs and corrosive substances more often than female (p < 0.0001). The number of drug abuse cases in 2019–2021 varied slightly, increasing by 2.4 and 6.7% annually. Synthetic narcotic substances were most common: methadone, cathinones, psychostimulants, and mixtures of substances. We discovered parallel trends in dynamics of ethanol intoxication and COVID-19 cases, and no such between drug poisonings and the said morbidity. Thus, the identified specifics of ACP patterns in the capital of Russia associated with the COVID-19 pandemic are a spike in alcohol abuse (especially among women), and lack of noticeable effect of the disease on use of drugs.
