The Hidden Toll: A Surge in Alcohol and Drug-Related Deaths During Brazil's Pandemic Years
Brazil faced an unprecedented crisis during the COVID-19 pandemic, not just from the virus itself but from a parallel 'silent epidemic' of substance-related mortality. A groundbreaking ecological study led by researchers at the Universidade Federal de Alagoas (UFAL) reveals that between 2015 and 2022, over 178,000 deaths were linked to psychoactive substances, with more than 80% attributed to alcohol. This research, published in The Lancet Regional Health – Americas in early 2026, highlights a dramatic shift: while pre-pandemic rates were stable or declining, deaths spiked sharply from 2020 onward, underscoring the devastating interplay of isolation, economic stress, and disrupted healthcare services.
The study, spearheaded by Professor Márcio Bezerra-Silva from UFAL's Complexo de Ciências Médicas e de Enfermagem in Arapiraca, analyzed data from Brazil's Sistema de Informações sobre Mortalidade (SIM). It employed advanced statistical models like Joinpoint regression and ARIMA interrupted time-series to quantify excess deaths against expected trends. This rigorous approach provides a clear picture of how the pandemic exacerbated vulnerabilities, particularly in mental health support and addiction treatment.
Pre-Pandemic Trends: Stability Gives Way to Crisis
Before March 2020, alcohol- and drug-related mortality in Brazil showed relative stability nationwide, with some regions even experiencing declines. Government data from the Observatório Brasileiro de Informações sobre Drogas (OBID) indicated consistent patterns, but underlying risks like heavy episodic drinking were already high. Fiocruz research from 2019 pegged alcohol-attributable deaths at 104,800 annually—about 12 per hour—with men accounting for 86%.
Brazilian universities like Fiocruz and UNIFESP had long warned of rising binge drinking among youth, but the pandemic acted as a catalyst. Isolation measures, job losses, and overwhelmed health systems interrupted routine interventions, setting the stage for escalation. This backdrop explains why the UFAL study found no significant upward trajectory until the pandemic hit.
Quantifying the Surge: Excess Deaths Year by Year
The UFAL analysis pinpointed stark increases: 18.3% excess deaths in 2020, 22.4% in 2021, and a peak of 26% in 2022 compared to pre-pandemic projections. Over 25,900 additional deaths occurred in the first three pandemic years alone. Nationally, mortality rates jumped post-March 2020, confirmed by statistical significance in time-series models.
Alcohol dominated, comprising over 80% of cases, while drugs like cocaine (26.7% in some OBID traffic death data) played a secondary but growing role. This 'epidemic within an epidemic' broke historical trends, with states like Pernambuco, Amapá, and Tocantins seeing over 50% spikes in certain years.
Demographic Vulnerabilities: Who Was Hit Hardest?
Young adults aged 20-39 saw an average annual percent change (AAPC) of 2%, while those 60+ experienced 1.8% rises. Men bore the brunt numerically, but women's rates grew faster at 4.6% AAPC versus 3.6% for men—a trend linked to increased home-based drinking and mental health strains.
University studies from UNESP and UFRGS echo this, noting higher substance use among students during lockdowns, often as coping mechanisms for anxiety. Fiocruz data reinforces gender disparities, with women facing rising cardiovascular risks from alcohol.
Regional Disparities: Northeast, Southeast, and South Lead Increases
Coroplectic maps from the UFAL study reveal hotspots: Northeast (up to 31.8% excess in 2022), Southeast (24.3% in 2021), and South (35.2% in 2022). Nearly every state registered growth, driven by urban isolation in São Paulo (USP-linked research) and economic woes in poorer regions.
Brazilian universities like UNICAMP have mapped similar patterns in São Paulo state, linking surges to disrupted CAPS-Ad (psychosocial care centers for alcohol/drugs). For more on higher ed career paths in public health, explore higher ed jobs in Brazil.

Led by Prof. Márcio Bezerra-Silva and co-authors including Prof. Maria Amélia Gurgel (UFAL/UFS), the study leveraged SIM's comprehensive mortality database. Joinpoint identified trend shifts, ARIMA modeled interruptions, and spatial analysis highlighted inequities. Limitations like underreporting were acknowledged, emphasizing the need for better data integration.
This exemplifies Brazilian higher education's role in evidence-based policy, with UFAL's Campus Arapiraca driving national insights. Similar efforts at Fiocruz quantify economic burdens, like R$18.8 billion annual alcohol costs.
University Research Echoes: Student and Youth Vulnerabilities
Beyond UFAL, UNIVASF, USP, and UNIFESP studies document spikes in university student alcohol use during lockdowns—up to elevated binge rates post-reopening. UFRJ research links pandemic stress to polysubstance use, urging campus interventions.

Root Causes: Isolation, Economics, and Healthcare Gaps
The pandemic's lockdowns fostered isolation, boosting home drinking; economic fallout hit low-income groups hardest; and mental health services faltered. OBID data shows cocaine-alcohol combos in 26% of traffic deaths, signaling polysubstance dangers.
Brazilian academics attribute this to reduced access to CAPS and AA groups, with UNIFESP noting anxiety-alcohol cycles. Solutions include telehealth expansions piloted by universities.
Implications for Public Health and Policy
The UFAL findings demand urgent reinvestment in addiction services. With 12 hourly alcohol deaths pre-pandemic (Fiocruz), post-surge totals strain SUS. Policymakers eye tax hikes on booze, inspired by global models.
