Argentina experienced two extensive lockdown periods. University education remained virtual for almost two academic years. The purpose of the present work was to analyze the impact of the COVID-19 lockdowns in Argentina on alcohol consumption, hangover severity and smoking among university students in Buenos Aires. A retrospective online survey was conducted in 2021 among students of the University of Buenos Aires. Participants aged 18\u201335 years old were asked about the average number of alcoholic drinks and number of drinking days per week, binge drinking occasions, drunkenness, next day hangover severity, number of hangovers per month, and smoking behavior. The results showed that the first and second COVID-19 lockdowns were associated with significant reductions in both weekly alcohol consumption, and hangover severity and subjective intoxication on their heaviest drinking occasions. Males consumed significantly more alcohol than females, and older students (25\u201335 years old) consumed more alcohol than younger students (18\u201324 years old). In addition, younger students reduced the number of cigarettes smoked per day during the two lockdown periods while older students exhibited significantly more smoking days per week. In conclusion, the present work in Argentinian students revealed a significant reduction in weekly alcohol consumption, and subjective intoxication and hangover severity on their heaviest drinking occasions during the pandemic lockdown periods.<\/jats:p>","DOI":"10.3390\/jcm12041491","type":"journal-article","created":{"date-parts":[[2023,2,13]],"date-time":"2023-02-13T07:01:23Z","timestamp":1676271683000},"page":"1491","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Alcohol Consumption, Hangovers, and Smoking among Buenos Aires University Students during the COVID-19 Pandemic"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0349-2771","authenticated-orcid":false,"given":"Analia","family":"Karadayian","sequence":"first","affiliation":[{"name":"Instituto de Bioqu\u00edmica y Medicina Molecular (IBIMOL), CONICET, Universidad de Buenos Aires, Buenos Aires 1113, Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5119-332X","authenticated-orcid":false,"given":"Agnese","family":"Merlo","sequence":"additional","affiliation":[{"name":"Division of Pharmacology, Utrecht Institute for Pharmaceutical Sciences, Utrecht University, Universiteitsweg 99, 3584CG Utrecht, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1168-8990","authenticated-orcid":false,"given":"Analia","family":"Czerniczyniec","sequence":"additional","affiliation":[{"name":"Instituto de Bioqu\u00edmica y Medicina Molecular (IBIMOL), CONICET, Universidad de Buenos Aires, Buenos Aires 1113, Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4269-5659","authenticated-orcid":false,"given":"Silvia","family":"Lores-Arnaiz","sequence":"additional","affiliation":[{"name":"Instituto de Bioqu\u00edmica y Medicina Molecular (IBIMOL), CONICET, Universidad de Buenos Aires, Buenos Aires 1113, Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9030-4432","authenticated-orcid":false,"given":"Pauline","family":"Hendriksen","sequence":"additional","affiliation":[{"name":"Division of Pharmacology, Utrecht Institute for Pharmaceutical Sciences, Utrecht University, Universiteitsweg 99, 3584CG Utrecht, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3073-9749","authenticated-orcid":false,"given":"Pantea","family":"Kiani","sequence":"additional","affiliation":[{"name":"Division of Pharmacology, Utrecht Institute for Pharmaceutical Sciences, Utrecht University, Universiteitsweg 99, 3584CG Utrecht, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2593-1488","authenticated-orcid":false,"given":"Gillian","family":"Bruce","sequence":"additional","affiliation":[{"name":"Division of Psychology and Social Work, School of Education and Social Sciences, University of the West of Scotland, Paisley PA1 2BE, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6455-2096","authenticated-orcid":false,"given":"Joris","family":"Verster","sequence":"additional","affiliation":[{"name":"Division of Pharmacology, Utrecht Institute for Pharmaceutical Sciences, Utrecht University, Universiteitsweg 99, 3584CG Utrecht, The Netherlands"},{"name":"Centre for Human Psychopharmacology, Swinburne University, Melbourne, VIC 3122, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"9","DOI":"10.1037\/tra0000996","article-title":"COVID-19 Disruption on College Students: Academic and Socioemotional Implications","volume":"13","author":"Tasso","year":"2021","journal-title":"Psychol.
