Drug use among medical students in São Paulo, Brazil: a cross-sectional study during the coronavirus disease 2019 pandemic

ABSTRACT BACKGROUND: Medical students demonstrate higher rates of substance use than other university students and the general population. The challenges imposed by the coronavirus disease 2019 (COVID-19) pandemic raised significant concerns about mental health and substance use. OBJECTIVES: Assess the current prevalence of substance use among medical students at the University of São Paulo and evaluate the impact of the COVID-19 pandemic on drug consumption. DESIGN AND SETTING: A cross-sectional study was conducted on 275 medical students from the University of São Paulo Medical School (São Paulo, Brazil) in August 2020. METHODS: Substance use (lifetime, previous 12 months, and frequency of use before and during the COVID-19 pandemic) and socioeconomic data were assessed using an online self-administered questionnaire. Symptoms of depression were assessed using the Patient Health Questionnaire-9. RESULTS: Alcohol was the most consumed substance in their lifetime (95.6%), followed by illicit drugs (61.1%), marijuana (60%), and tobacco (57.5%). The most commonly consumed substances in the previous year were alcohol (82.9%), illicit drugs (44.7%), marijuana (42.5%), and tobacco (36%). Students in the first two academic years consumed fewer substances than those from higher years. There was a decreasing trend in the prevalence of most substances used after the COVID-19 pandemic among sporadic users. However, frequent users maintained their drug use patterns. CONCLUSION: The prevalence of substance use was high in this population and increased from the basic to the clinical cycle. The COVID-19 pandemic may have affected the frequency of drug use and prevalence estimates.

Pharmacological Treatment of Alcohol Cravings.

(1) Background: The treatment of substance addiction is challenging and has persisted for decades, with only a few therapeutic options. Although there are some recommendations for specific treatments for Alcohol Use Disorder (AUD), there is no specific medication used to treat alcohol cravings, which could benefit millions of patients that are suffering from alcoholism. Cravings, or the urge to use drugs, refer to the desire to experience the effects of a previously experienced psychoactive substance. (2) Methods: We included original studies of alcohol abuse or dependence extracted from a controlled, blind, pharmacological treatment study which presented measures and outcomes related to alcohol cravings. (3) Results: Specific drugs used for the treatment of alcoholism, such as Naltrexone and Acamprosate, have had the best results in relieving craving symptoms, as well as promoting abstinence. Baclofen and anticonvulsants such as Gabapentin and Topiramate have shown good results in promoting abstinence and the cessation of cravings. (4) Conclusions: Specific drugs used for the treatment of alcoholism to obtain the best results can be considered the gold standard for promoting abstinence and relieving cravings. Anticonvulsants and Baclofen also had good results, with these medications being considered as second-line ones. Varenicline is an option for alcohol dependents who also concomitantly ingest tobacco.

Toxicity of Synthetic Cannabinoids in K2/Spice: A Systematic Review.

(1) Background: Synthetic cannabinoids (SCs) are emerging drugs of abuse sold as 'K2', 'K9' or 'Spice'. Evidence shows that using SCs products leads to greater health risks than cannabis. They have been associated with greater toxicity and higher addiction potential unrelated to the primary psychoactive component of marijuana, Δ9-tetrahydrocannabinol (Δ9-THC). Moreover, early cases of intoxication and death related to SCs highlight the inherent danger that may accompany the use of these substances. However, there is limited knowledge of the toxicology of Spice ingredients. This systematic review intends to analyze the toxicity of SCs compounds in Spice/K2 drugs. (2) Methods: Studies analyzing synthetic cannabinoid toxicity and dependence were included in the present review. We searched the PubMed database of the US National Library of Medicine, Google Scholar, CompTox Chemicals, and Web of Science up to May 2022. (3) Results: Sixty-four articles reporting the effects of synthetic cannabinoids in humans were included in our review. Ten original papers and fifty-four case studies were also included. Fourteen studies reported death associated with synthetic cannabinoid use, with AB-CHMINACA and MDMB-CHMICA being the main reported SCs. Tachycardia and seizures were the most common toxicity symptoms. The prevalence of neuropsychiatric symptoms was higher in third-generation SCs. (4) Conclusion: SCs may exhibit higher toxicity than THC and longer-lasting effects. Their use may be harmful, especially in people with epilepsy and schizophrenia, because of the increased risk of the precipitation of psychiatric and neurologic disorders. Compared to other drugs, SCs have a higher potential to trigger a convulsive crisis, a decline in consciousness, and hemodynamic changes. Therefore, it is crucial to clarify their potential harms and increase the availability of toxicology data in both clinical and research settings.

Os efeitos de um treinamento sobre humanização entre médicos comparados a não médicos / The effects of humanization training comparing doctors and non-doctors

Resumo: Introdução: A categoria médica vem sendo considerada pouco competente nos atributos relacionados à humanização. Por isso, mundialmente e no Brasil, mudanças têm sido realizadas nas grades dos cursos de graduação em Medicina para ampliar as disciplinas de humanidades. Além dessas iniciativas, há necessidade de treinamentos em humanização para médicos que se formaram com grades antigas e aqueles que, mesmo graduados a partir das novas diretrizes curriculares, ainda precisam se atualizar na temática. Há poucos estudos quantitativos sobre treinamentos em humanização, especialmente para médicos. Objetivo: Este estudo teve como objetivo avaliar os efeitos de um treinamento sobre humanização para médicos em comparação a não médicos. Método: Realizaram-se treinamentos de 135 minutos sobre humanização para médicos e não médicos em um hospital psiquiátrico universitário em São Paulo (Brasil). As aulas foram ministradas com o uso de slides e acompanhadas de discussão e dramatização. Os sujeitos da pesquisa responderam a um questionário com 34 itens que avaliavam as autopercepções sobre conhecimentos, habilidades e atitudes em humanização antes e 15 dias depois do treinamento. Utilizaram-se testes não paramétricos para comparar os escores entre o grupo de médicos e não médicos. Além disso, realizaram-se regressões lineares múltiplas para as dimensões de conhecimentos, habilidades e atitudes, com o objetivo de avaliar se houve diferença significativa entre gêneros, idades, estados civis, número de filhos, vínculos profissionais, religião, anos de serviço. Resultado: Profissionais médicos e aqueles com seis ou mais anos de serviço apresentaram menores escores em humanização no pré-treinamento. O treinamento gerou aumento dos escores de humanização em todas as categorias profissionais, mas médicos apresentaram maior aumento e se igualaram às outras categorias. Conclusão: Com um treinamento rápido e de baixo custo, verificou-se o aumento da autopercepção em humanização em médicos e não médicos. A diferença entre as categorias profissionais deixou de existir na avaliação realizada após 15 dias do treinamento. Os resultados indicam que médicos podem aumentar suas autopercepções sobre humanização e se igualar aos outros profissionais.

Abstract: Introduction: The medical category has been considered of little competence regarding the attributes related to humanization. As such, changes have been made in the course curriculums of undergraduate medical courses in Brazil and worldwide to expand the Humanities disciplines. In addition to these initiatives, humanization training is needed for doctors who graduated under the aegis of old curriculums and for those who - even though they graduated with the new curricular guidelines - still need to be updated on the subject. There are few quantitative studies about humanization training, especially for medical doctors. Objective: To evaluate the effects of humanization training on doctors in comparison with non-doctors. Method: Humanization trainings lasting 135 minutes were conducted for doctors and non-doctors in a psychiatric university hospital in São Paulo (Brazil). The classes were conducted with the use of slides and included discussions and a role-playing activity. The research subjects answered a questionnaire with 34 items assessing their self-perceptions about the knowledge, skills and attitudes in humanization before and 15 days after the training. Nonparametric tests were used to compare the scores between the group of doctors and non-doctors. Moreover, multiple linear regressions were performed for the knowledge, skills and attitude dimensions aiming to evaluate whether there was a significant difference between genders, age ranges, marital status, number of children, jobs, religion, years of service. Result: Medical professionals and those with six or more years of service had lower humanization scores at the pre-training moment. The training resulted in an increase in humanization scores in all professional categories, but physicians showed a greater increase and reached the same level as the other categories. Conclusion: A fast and low-cost training resulted in an increase in the self-perception of humanization in doctors and non-doctors. The difference between the professional categories ceased to exist in the evaluation carried out 15 days after the training. The results suggest that doctors can increase their self-perception about humanization and reach the same level as other professionals.

Bariatric surgery and its influence on alcohol consumption: Differences before and after surgery - A systematic review and meta-analysis.

BACKGROUND: Through new publications on the subject, the main goal of this article is to seek a change in the pattern of alcohol use before and after bariatric surgery. METHODS: We searched the National Library of Medicine, CINAHL, and PsycINFO databases. We included original articles regarding alcohol consumption before and after bariatric surgery to conduct the systematic review. RESULTS: Our systematic review, which included 18 articles, yielded mixed results. Meta-analysis of six articles did not reveal statistically significant differences in alcohol use behaviours before and one year after bariatric surgery. However, throughout the perspective of follow-up after bariatric surgery, nine out of the twelve articles showed improvement in the pattern of alcohol consumption when evaluated up to two years after the end of the surgical period, and four out of the five articles with monitoring beyond two years showed worsening in consumption, compared to pre-surgery alcohol use behaviours. CONCLUSIONS: Conclusions about the relationship between alcohol consumption and bariatric surgery are challenging primarily because of the variety of the methods used and the alcohol consumption measures. Despite that, our research pointed to an increased risk of alcohol use disorders two years after bariatric surgery.

Pharmacological Treatments for Cocaine Craving: What Is the Way Forward? A Systematic Review.

BACKGROUND: cocaine craving is a core feature of cocaine use disorder and remains a critical challenge for abstinence and relapse prevention. This review summarizes the anti-craving efficacy of pharmacotherapies tested for cocaine use disorder, in the context of randomized-controlled clinical trials. OBJECTIVES: we assessed the databases of the U.S. National Library of Medicine, Google Scholar, and PsycINFO, without date restrictions up to August 2022, to identify relevant studies. STUDY ELIGIBILITY CRITERIA, PARTICIPANTS, AND INTERVENTIONS: we included double-blinded randomized-controlled trials investigating pharmacotherapies for cocaine craving and/or cocaine use disorder whose outcomes included cocaine craving. STUDY APPRAISAL AND SYNTHESIS METHODS: Two authors screened studies' titles and abstracts for inclusion, and both read all the included studies. We systematically gathered information on the following aspects of each study: title; author(s); year of publication; sample size; mean age; sample characteristics; study set-ting; whether participants were treatment-seeking; study design; craving measures; study interventions; drop-out rates; and other relevant outcomes. RESULTS: Overall, we appraised 130 clinical trials, including 8137 participants. We further considered the drugs from the studies that scored equal to or greater than six points in the quality assessment. There was a correlation between craving and cocaine use outcomes (self-reports, timeline follow-back or urinary benzoylecgonine) in the vast majority of studies. In the short-term treatment, acute phenylalanine-tyrosine depletion, clonidine, fenfluramine, meta-chlorophenylpiperazine (m-CPP) and mecamylamine presented promising effects. In the long term, amphetamine, biperiden, carbamazepine, lisdexamfetamine, lorcaserin, methamphetamine, mirtazapine, pioglitazone, progesterone, guanfacine, levodopa, nefazodone presented promising anti-craving effects. Unfortunately, the highly tested medications were not successful in most of the trials, as follows: propranolol in the short term; amantadine, aripiprazole, bromocriptine, citicoline, ketamine, modafinil, olanzapine, topiramate in the long term. The remaining 52 medications had no positive anti-craving outcomes. LIMITATIONS: Our review was limited by high heterogeneity of craving assessments across the studies and by a great range of pharmacotherapies. Further, the majority of the studies considered abstinence and retention in treatment as the main outcomes, whereas craving was a secondary outcome and some of the studies evaluated patients with cocaine use disorder with comorbidities such as opioid or alcohol use disorder, schizophrenia, bipolar disorder or attention deficit hyperactivity. Lastly, most of the studies also included non-pharmacological treatments, such as counseling or psychotherapy. CONCLUSIONS: There is a direct association between craving and cocaine use, underscoring craving as an important treatment target for promoting abstinence among persons with cocaine use disorder. Clonidine, fenfluramine and m-CPP showed to be promising medications for cocaine craving in the short-term treatment, and amphetamine, biperiden, carbamazepine, lisdexamfetamine, lorcaserin, methamphetamine, mirtazapine, pioglitazone, progesterone, guanfacine, levodopa, nefazodone in the long-term treatment.

The impact of discrimination on substance use disorders among sexual minorities.

This paper aimed to review the literature regarding the impact of discrimination on substance use disorders among Sexual Minorities (SM), with a focus on alcohol, opioids, stimulants, polydrug use, chemsex, cannabis and tobacco, as well as inequalities in the access to health care services. It is alarmingly clear that SM report higher rates of morbidity if compared to the general population. Health care delivery inequalities have also been reported in this special population. Also, the lack of data from low- and middle-income countries on substance use among SM is a major concern. Certainly, discrimination play a key-role among leading factors to substance abuse, continued use, disorders, and lower levels of preventive and treatment interventions. However, it may be difficult to estimate the impact of discrimination because of the lack of research data and different methodologies of literature studies. Moreover, SM are differently categorized and defined and evidences may be not comparable between studies. There is an urgent need of strategic guidelines and research investments aimed at prioritizing these populations disproportionately impacted by substance use. Equity-oriented policies and programs can facilitate opportunities and decrease substance use in these vulnerable subgroups, including community- and peer-led initiatives and nonjudgmental and inclusive health services.

Dimensions of emotional distress among Brazilian workers in a COVID-19 reference hospital: A factor analytical study.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic is an unprecedented challenge for public health and has caused the loss of millions of lives worldwide. Hospital workers play a key role in averting the collapse of the health system, but the mental health of many has deteriorated during the pandemic. Few studies have been devoted to identifying the needs of workers on frontline duty. AIM: To investigate dimensions of common emotional symptoms and associated predictors among Brazilian workers in a COVID-19 reference hospital. METHODS: This is an observational study of the mental health of professionals in a COVID-19 hospital in the city of São Paulo. We invited all hospital employees to respond to an online survey between July and August 2020, during the first peak of the pandemic. Data of 1000 participants who completed the survey were analyzed (83.9% were women and 34.3% were aged 30 to 40). Hospital workers self-reported the presence of symptoms of depression, anxiety, trauma-related stress, and burnout through the Patient Health Questionnaire-9, the Generalized Anxiety Disorder-7, the Impact of Event Scale-Revised and the Mini-Z Burnout Assessment respectively. Responses were assembled and subjected to exploratory factor analysis to reveal workers' core emotional distress. Multiple linear regression models were subsequently carried out to estimate the likelihood of dimensions of distress using questions on personal motivation, threatening events, and institutional support. RESULTS: Around one in three participants in our sample scored above the threshold of depression, anxiety, post-traumatic stress disorder, and burnout. The factor analysis revealed a three-factor structure that explained 58% of the total data variance. Core distressing emotional domains were avoidance and re-experience, depression-anxiety, and sleep changes. Regression analysis revealed that institutional support was a significant protective factor for each of these dimensions (ß range = -0.41 to -0.20, P < 0.001). However, participants' personal motivation to work in healthcare service was not associated with these emotional domains. Moreover, the likelihood of presenting the avoidance and re-experience dimension was associated with having a family member or close friend be hospitalized or die due to COVID-19 and having faced an ethical conflict. CONCLUSION: Distressing emotional domains among hospital workers were avoidance and re-experience, depression and anxiety, and sleep changes. Improving working conditions through institutional support could protect hospital workers' mental health during devastating public health crises.

Immigrants, refugees and cannabis use.

Immigration typically occurs from low- to high-income countries and regions. Unfortunately, these wealthier areas also have higher rates of cannabis use (e.g. European Union and the US). This systematic review aimed to summarize available studies on cannabis use among immigrants, refugees, and asylum seekers. In addition, evidence on the association between immigration and cannabis use was reviewed. The rates of cannabis use were lower among immigrants than natives. The risk and protective factors to cannabis use were quite similar to those of the native populations. The population at greatest risk for cannabis use were refugees, males, singles, non-religious, those with lower educational level, living in urban areas, with friends that use cannabis and/or other drugs. Cannabis use tend to increase over generations, and acculturation seems to play a pivotal role. First generation migrants report equal or lower consumption of cannabis when compared with the majority population with a subsequent increase in following generations, with a clear association with acculturation factors. A higher cannabis use was found among migrants with lower cultural congruity as well as a higher level of culture assimilation. This use seems to be unrelated to alcohol or illicit drugs consumption, but possibly associated with tobacco smoking.

COMVC-19: A Program to protect healthcare workers' mental health during the COVID-19 Pandemic. What we have learned.

OBJECTIVE: In 2020, the COVID-19 pandemic brought a work and stress overload to healthcare workers, increasing their vulnerability to mental health impairments. In response, the authors created the COMVC-19 program. The program offered preventive actions and mental health treatment for the 22,000 workers of The Hospital das Clinicas da Faculdade de Medicina da Universidade de São Paulo (HCFMUSP). This paper aims to describe its implementation and share what we have learned from this experience. METHODS: Workers were able to easily access the program through a 24/7 hotline. Additionally, a mobile phone app that screened for signs and symptoms of emotional distress and offered psychoeducation and/or referral to treatment was made available. Data from both these sources as well as any subsequent psychiatric evaluations were collected. RESULTS: The first 20 weeks of our project revealed that most participants were female, and part of the nursing staff working directly with COVID-19 patients. The most frequently reported symptoms were: anxiety, depression and sleep disturbances. The most common diagnoses were Adjustment, Anxiety, and Mood disorders. CONCLUSIONS: Implementing a mental health program in a multimodal intervention was feasible in a major quaternary public hospital. Our data also suggests that preventive actions should primarily be aimed at anxiety and depression symptoms, with a particular focus on the nursing staff.

Exploring the Role of Alcohol Metabolizing Genotypes in a 12-Week Clinical Trial of Naltrexone for Alcohol Use Disorder.

Background: The efficacy of naltrexone in the treatment of alcohol use disorder (AUD) has been associated with a set of variables not directly related with the expression of opioid receptors. All the variables have been found to be highly associated with AUD itself or more severe clinical levels of AUD. Objectives: Given the high association between alcohol metabolizing enzymes (AME) and the outcome of AUD, the present study aims to investigate the role of AME genotype variants in the treatment of AUD with naltrexone. Methods: We carried out a 12-week longitudinal clinical trial based on the treatment of AUD patients with naltrexone (N = 101), stratified by different alcohol metabolization genotypes. Genotyping was performed after the inclusion of the patients in the study, based on the individual presence of single nucleotide polymorphisms (SNPs) in the ADH (alcohol dehydrogenase)1B (ADH1B*2 and ADH1B*3), ADH1C (ADHC*1) and ALDH (aldehyde dehydrogenase) 2 (ALDH2*2) genes. The outcome of alcohol use has been monitored employing the timeline follow-back during the treatment. Results: The ADH1C*1 (Ile350Val, rs698) and ALDH2*2 (Glu504Lys, rs671) polymorphisms were associated with a better response to naltrexone treatment, whereas the ADH1B*3 (Arg370Cys, rs2066702) allelic variant showed a negative outcome. Conclusions: The present study explores a genomic setting for the treatment of AUD with naltrexone. According to our findings, the association between ADH1C*1 and ALDH2*2 variants and better outcomes suggests a successful treatment, whereas the ADH1B*3 mutated allele might lead to an unsuccessful treatment. Further studies should be performed to investigate the relationship between alcohol metabolizing genotypes, the family history of alcohol use disorders and the effect of naltrexone on the outcomes. Genotyping may be a valuable tool for precision-medicine and individualized approach, especially in the context of alcohol use disorders. The small number of subjects was the main limitation of the present study.

Postmortem qualitative analysis of psychological, occupational, and environmental factors associated with lethal anesthetic and/or opioid abuse among anesthesiologists: case series.

BACKGROUND: Anesthetic and/or opioid abuse is more prevalent among anesthesiologists than in other medical specialties and it has been associated with high mortality. The aim of this study was to evaluate factors associated with lethal anesthetic and/or opioid abuse among anesthesiologists. METHODS: We evaluated psychological factors, and occupational history and circumstances of death of anesthesiologists who died from anesthetic abuse. Data were obtained post-mortem from colleagues, and relatives. After finding eligible cases, we identified the key informants, who were interviewed personally or via email, through the qualitative method known as "Psychological Autopsy". RESULTS: Eighteen cases of death were identified, but we were able to interview 44% of them (n = 8), most of whom were young males. They died at home or at the hospital and were found "at the scene". Being an introspective person who did not share personal issues at workplace was the most prevalent personal characteristic. At work, they seemed to perform very well their functions, but some presented subtle changes such as to staying more than usual at the workplace and/or neglecting some of their responsibilities. The main reported factors to explain their substance abuse were emotional problems including psychiatric, excessive hours of work, and other health factors. CONCLUSION: This study identified that emotional disturbances, compulsive work, and general health problems were the more prominent factors involved with those deaths. Further, larger studies are needed to better understand how these factors could be early identified in order to timely prevent anesthetic and/or opioid abuse and several deaths among anesthesiologists.

Investigating gender differences for effectiveness and side effects of varenicline during smoking cessation treatment.

Varenicline is a useful pharmacological option for smoking cessation. Unfortunately, there is a lack of studies on its effectiveness, retention, and side effects in low- and middle-income countries. The present study aimed to investigate gender differences regarding these outcomes in a Brazilian clinical sample (n = 124). The 12-week treatment protocol included six consultations with a psychiatrist and six sessions of cognitive-behavioral therapy. All subjects received varenicline on the first evaluation, following the standard posology for 12 weeks and instructions to stop smoking after the second week of treatment. Both Mini-International Neuropsychiatric Interview (MINI) Plus and Fagerstrom Test for Nicotine Dependence were applied at baseline. The UKU-Side Effects Rating Scale was administered at weeks 3, 7, and 11, and the Questionnaire of Smoking Urges-Brief at weeks 1, 5, and 9 to ascertain the side effects of the medication and craving, respectively. At the end of the 12-week treatment, abstinence was biochemically assessed. At months 6 and 12 after the treatment, follow-up telephone interviews were conducted to access nicotine abstinence. Short- and long-term abstinence and retention rates did not differ between genders. However, women presented more side effects than men, especially in the second half of the treatment. Increased dream activity, reduced duration of sleep, constipation, and weight loss were the most notable side effects. Despite women reporting more side effects than men, this difference did not influence the treatment success rates.

RESUMO A vareniclina é uma opção farmacológica útil para a cessação do tabagismo. Infelizmente, há uma ausência de estudos sobre a eficácia, retenção e efeitos colaterais para este medicamento em países de baixa e média renda. O presente estudo teve como objetivo investigar diferenças entre gênero em relação a esses desfechos em uma amostra clínica brasileira (n = 124). O protocolo de tratamento de 12 semanas incluiu seis consultas com um psiquiatra e seis sessões de psicoterapia cognitivo-comportamental. Todos os indivíduos receberam vareniclina na primeira avaliação, seguindo a posologia padrão por 12 semanas e instrução para parar de fumar a partir da segunda semana de tratamento. Tanto o Mini-International Neuropsychiatric Interview (MINI) Plus quanto o Teste de Fagerstrom para Dependência de Nicotina foram aplicados no início do estudo. A escala de efeitos colaterais (UKU-Side Effects Rating Scale) foi aplicada nas semanas 3, 7 e 11, e o Questionário Breve de Fissura (Questionnaire of Smoking Urges-Brief) nas semanas 1, 5 e 9 para investigar os efeitos colaterais da medicação e fissura, respectivamente. No final do tratamento de 12 semanas, a abstinência foi avaliada bioquimicamente. Aos 6 e 12 meses após o tratamento, foram realizadas entrevistas telefônicas de acompanhamento para acessar a abstinência de nicotina. As taxas de abstinência e retenção de curto e longo prazo não diferiram entre gêneros. No entanto, as mulheres apresentaram mais efeitos colaterais do que os homens, principalmente na segunda metade do tratamento. Aumento da atividade dos sonhos, redução da duração do sono, constipação e perda de peso foram os efeitos colaterais mais notáveis. Apesar de as mulheres relatarem mais efeitos colaterais que os homens, essa diferença não influenciou as taxas de sucesso do tratamento.

Alcohol Use and COVID-19: Can we Predict the Impact of the Pandemic on Alcohol Use Based on the Previous Crises in the 21st Century? A Brief Review.

The enormous health and economic challenges precipitated by the 2019 coronavirus disease (COVID-19) pandemic are comparable or even greater than those associated with previous historical world crises. Alcohol use, especially drinking to cope with stress, is a concern, as an increase in its sales has been reported in some countries during the quarantine. This study aims to provide a better understanding of what to expect in terms of alcohol consumption, risk factors for excessive use, and its potential consequences during this pandemic based on previous experiences. We investigated how traumatic events related to alcohol consumption. Studies on mass traumatic events (i.e., terrorism as 9/11), epidemic outbreaks (i.e., severe acute respiratory syndrome [SARS] in 2003), economic crises (such as 2008's Great Recession), and COVID-19 were selected. The main keywords used to select the studies were alcohol use, drinking patterns, alcohol use disorders, and alcohol-related consequences. Previous studies reported increases in alcohol use associated with those events mediated, at least partially, by anxiety and depressive symptoms, and posttraumatic stress disorder (PTSD). Being male, young, and single also seems to be associated with a higher vulnerability to develop risky drinking behavior after those tragic events. The discussion of previous risk and protective factors can contribute to elaborate more specific public health policies to mitigate the impact of the current pandemic on people's mental health, especially alcohol-related problems.
