Escaping the past and living in the present: a qualitative exploration of substance use among Syrian male refugees in Germany

Psychoactive substance use among Russian migrants relocated in Georgia following the 2022 invasion of Ukraine: Qualitative study

INTRODUCTION

Study aimed at exploring the experience of migrants from Russia who use psychoactive substances, who arrived in Georgia in the wake of the invasion of Ukraine.

METHODS

Qualitative individual interviews and focus group discussions. The data collection took place from May to August 2023.

RESULTS

The final sample consisted of 23 respondents, who were mostly young and employed. Participants left Russia because of the war in Ukraine and the threat of conscription in Russia, but also due to political dissent. Participants experienced depressive symptoms and a worsening of mental health conditions. The increased consumption of sedatives and alcohol was closely associated with the efforts to manage stress and depression, acting as a means to cope with adverse effects on mental health. The absence of leisure alternatives emerged as a significant factor, with drug use becoming a feature of socialising in circumstances where such behaviour was not typical in their Russian lives. Participants exhibited low awareness of available relevant health services (including drug-related) and typically addressed recurrent health needs by consulting Russian specialists online or Russian-speaking professionals within Georgia's migrant community.

DISCUSSION AND CONCLUSIONS

Migration was associated with a deterioration in mental health status and substance use often manifested as a maladaptive strategy to cope with mental health problems. The difficulties encountered in the process of assimilation contributed to behaviours related to drug consumption. Immigration policies need to be inclusive of the health needs of migrants and provide opportunity to integrate effectively into society.

Special needs of refugees with substance use disorders from conflict-affected countries: a comparison with German-born individuals

BACKGROUND

Refugees seem to be at enhanced risk for substance use disorders. At the same time, they have less access to services and their health needs remain poorly understood. This study aims to evaluate the specific needs of refugees as compared to German-born individuals seeking help for substance use disorders.

METHODS

We conducted an observational case-control study using all treatment episodes in outpatient addiction facilities in three German federal states during the year 2020. A total of 719 refugee clients were matched to 713 German-born individuals using propensity score matching. We compared potential needs related to features of substance use as well as different psychosocial areas.

RESULTS

The final sample of refugees was composed of n = 384 (26.8%) cases from Afghanistan, n = 214 (14.9%) from Syria and n = 121 (8.4%) from Iraq. Clients consulted mostly due to cannabis use (44.8%) or opioid use (20.1%). Intravenous use of drugs and needle sharing was significantly lower in refugees (p < 0.05). A higher proportion of refugees than Germans lived in provisional housing, were unemployed or in charge of minor children (p < 0.05). Mental and physical comorbidities were significantly higher in refugees (p < 0.05). They were also more likely to have been victims of violence and less likely to present violent behaviors.

CONCLUSION

Refugees with substance use disorders differ regarding a spectrum of psychosocial issues from German-born individuals. This highlights the need to link addiction treatment with other parts of the health care and psychosocial support systems to provide adequate care for this group.

Criminological and Psychiatric Profiles of Immigrant and Refugee Offenders: A Retrospective Analysis of Cases in a Forensic Setting

This study aimed to scrutinize the characteristics of immigrant and refugee offenders within our institution, focusing on factors such as immigrant status, country of birth, duration of residence in Turkey, as well as psychiatric, socio-demographic, and criminal profiles. The data were obtained through a retrospective examination of case records referred to the Observation Department of the Council of Forensic Medicine for the assessment of criminal responsibility between 2017 and 2022. The study categorized the cases into two groups: refugees and immigrants, comprising 35 and 22 offenders, respectively. Significant differences in educational levels were identified between immigrants and refugees within our study group (p < .001). Notably, drug use disorders were more prevalent among refugees, whereas alcohol use disorders were more common among immigrants, with statistical significance (p < .005). During forensic psychiatric assessments, 57.1% of refugees and 54.5% of immigrants required interpretation services. The most prevalent offense in the refugee group was homicide (37.1%), followed by child sexual abuse (28.6%). In contrast, homicide (31.8%) and theft and extortion (22.7%) were the most common offenses for the immigrant group. Six cases (10.5%) were judged to have reduced or no criminal liability. Among the cases, 52.6% had a history of prior outpatient psychiatric referrals, with the most frequent diagnosis being atypical psychosis at 10.5%. The findings underscore the necessity for additional research and targeted interventions to address the mental health and criminological complexities confronted by this vulnerable population.

War, forced displacement, and alcohol abuse: experiences and perceptions of war-affected south Sudanese refugee youth living in Bidibidi refugee settlement in northern Uganda

Refugees are at high risk of alcohol abuse due to their experiences of structural, physical, sexual, and psychological violence in their countries of origin, during flight, and within host communities. Given the prolonged civil war in their country, South Sudanese have continued to flee profound forms of violence and now constitute the largest population of refugees in Uganda. However, little is known about their displacement experiences, as well as the reality of alcohol use and abuse within refugee settlements. Drawing upon the direct voices of a sample of war-affected South Sudanese young people, this article explores their experiences of forced displacement and their links to alcohol abuse, as well as their perceptions regarding appropriate alcohol treatment interventions for refugees in the camp. A total of 22 semi-structured qualitative interviews were conducted with 14 refugee youth (aged 18-25) alongside eight adult key informants who work with the youth (religious leaders, sports coaches, educators, social workers, and settlement administrators). Using thematic analysis, the study revealed a series of key themes influencing and shaping the high incidence of alcohol abuse among the youth. These included traumatic wartime and migration experiences, family separation, poor prospects, and the ubiquitous availability of alcohol in the settlement. In addition, we show how alcohol operates as a strategic tool for survival for the youth, as well as highlight how these perceptions can help to inform alcohol treatment interventions in the Bidibidi refugee settlement. To our knowledge, this is the first in-depth study of alcohol abuse among war-affected South Sudanese refugee youth in Uganda, addressing a significant gap in the current literature on war-affected youth, forced displacement, and alcohol abuse. We contend that involving youth in the design of interventions can be helpful for culturally sensitive and relevant prevention, treatment, and care in refugee settings. In addition, providing employment opportunities and meaningful engagement for growth through social participation can help to address harmful alcohol use among youth in the camps.

Good practice in reaching and treating refugees in addiction care in Germany - a Delphi study

BACKGROUND

Health and adequate access to health care are human rights. Refugees are at risk for substance abuse. Despite the known structural and personal risk factors for abuse, refugees in Germany continue to face barriers to adequate addiction prevention and care, which is a violation of the fundamental human right to health care. The question arises as to how barriers for refugees in reaching addiction services and care can be overcome. In the presented study, strategies for good practices to deconstruct these barriers were identified.

METHOD

A total of 21 experts participated in a three-round, consensus-oriented Delphi-Process. The experts represented five different fields: addiction care services, including specialized programs for women, refugee aid services, academia, policy-making and immigrants' self-help services.

RESULTS

The Delphi-Process generated 39 strategies of good practice summarized in 9 major categories: Care System, Framework Conditions, Multilingualism, Information and Education, Access, Service-Level, Employee-Level, Employee-Attitudes and Networking.

CONCLUSION

In order to guarantee human rights regarding health and adequate access to health care for refugees, institutional barriers limiting access to prevention and treatment programs for addictive disorders must be abolished. The identified good practice strategies for Germany, if widely implemented, could contribute to this aim. By opening up prevention and treatment facilities for refugees, other marginalized groups could also benefit. While some of the strategies need to be implemented at the institutional level, political steps are also required at the system level including, e.g. financing of adequate translation services.

The burden of substance use and (mental) distress among asylum seekers: a cross sectional study

Background

Asylum seekers are a particularly vulnerable population due to a wide range of external stressors. Traumatic events and difficult social/economic prospects can lead to an elevated susceptibility for substance use disorders. The aim of the present study was to determine whether asylum seekers suffering from mental or physical distress present higher levels of substance use disorder (SUD) in a state reception center in Germany and whether there are identifiable risk or protective factors.

Methods

We performed a hierarchical logistic regression on data of N = 238 people who had applied for asylum in Germany to analyze the SUD variance explanation by (1) sociodemographic, (2) flight-specific, and (3) psychometric (ERQ, SOC-9 L, SCL-K9) variables. On level (4), we included the location of data collection (walk-in clinic or accommodation,) as an indicator of individual's need for a psychologist's or General practitioner's help in order to assess for the participant's (mental) distress.

Results

Low educational level, lower sense of coherence, and mental distress (location of data collection in the psychosocial or general medical outpatient clinic) were associated with SUD. Those suffering from SUD seemed to be less aware of external stressors as SUD was also associated with low levels of reported post-migratory stress.

Discussion

The association of SUD with psychological distress and lower education reaffirms the concept that some vulnerable groups are at a higher risk for substance-related difficulties. Strengthening the sense of coherence with targeted interventions might enable at-risk groups to cope better with forthcoming burdens and help with abstaining from current or future consumption.

Challenges in substance use treatment as perceived by professionals and Arabic-speaking refugees in Germany

BACKGROUND

Substance use (SU) and substance use disorders (SUDs) have been recently documented among forcibly displaced populations as a coping mechanism to migration and postmigration stressors. Although the literature exploring substance use among refugees has grown recently, little is known about SU among Arabic-speaking refugees and, more specifically, on the challenges and experiences in regards to SU treatment. This study investigates this topic from the perspectives of Arabic-speaking refugees and professionals in Germany.

METHODS

Design and participants To expand our knowledge on this topic, a qualitative approach was employed by conducting in-depth and semi-structured interviews among 26 participants (13 refugees and 13 professionals) in Germany during 2020-2021. Purposive sampling was used to recruit Arabic-speaking refugees in two rehabilitation centers in Berlin. Data and analysis Interviews were conducted with 26 participants of which 13 were refugees and 13 professionals. Refugees were interviewed individually in the rehabilitation centers, they ranged from 21 to 52 years of age, and their average time in Germany was 6.3 years. An open-ended survey was conducted among the professionals via the SoSci-survey platform, and they ranged from 22 to 66 years of age, with an average of 5 to 9 years of work experience. Data were analyzed using thematic analysis.

RESULTS

Three themes resulted from the thematic analysis: (1) The treatment is facilitated by institutional and emotional support; (2) The affected refugees struggle with complex contextual barriers to access SUD treatment; and (3) Individual and community preventive strategies are needed.

CONCLUSIONS

This study provides insight into the support and challenges of accessing effective SU treatment and prevention among Arabic-speaking refugees in Germany. Collaborative efforts by the community, professionals, and policymakers are needed to facilitate access to effective treatment and implement culturally and linguistically sensitive approaches for the treatment and prevention of SU among refugees.

Epidemiology of substance use and mental health disorders among forced migrants displaced from the MENAT region: A systematic review and meta-analysis protocol

BACKGROUND

Understanding the epidemiology of substance use disorders (SUDs) and mental health disorders (MHDs) among forced migrants from the Middle East and North Africa and Türkiye (MENAT) region is of utmost importance given their distinct challenges and vulnerabilities. Existing research on the topic is substantial; however, comprehensive systematic reviews are limited. We aim to conduct a systematic literature review to bridge this gap, providing a thorough understanding of SUDs and MHDs epidemiology among this population.

METHODS

The systematic review will include original, peer-reviewed research articles published in English or Arabic between 2013 and 2023. It will encompass qualitative, quantitative, and mixed-methods studies focusing on SUDs and/or MHDs among forced migrants from the MENAT region. A Medline (via Ovid) search strategy was developed and will be translated into databases of EMBASE (via Ovid), Web of Science Core Collection (as licensed at Yale), and CINAHL. Risk of Bias in the included studies will be assessed using the Joanna Briggs Institute (JBI) checklist for observational studies and the Cochrane Risk of Bias (ROB) 2 tool for intervention studies. Meta-analysis using random-effects models will be conducted and subgroup analyses based on studies' data will be performed. The systematic review will be conducted based on the framework introduced by the Joanna Briggs Institute. Additionally, the PRISMA-P extension for systematic reviews was used to report the present protocol. The present systematic review protocol has been registered with PROSPERO, an international prospective register of systematic reviews. The review's registration ID is CRD42021286882.

DISCUSSION

The systematic review aims to explore, identify and synthesize the evidence to reveal the epidemiology of SU and/or MH of forced migrants of the MENAT region as described in this protocol. In sum, the review will provide evidence to fill the gap in the literature and help the stakeholders, policymakers, and health providers to expand current knowledge of the prevalence and risk factors of SU and/or MH in humanitarian settings.

Alcohol and other drug use patterns and services in an integrated refugee settlement in Northern Zambia: a formative research study

BACKGROUND

Evidence on patterns of alcohol and other drug (AOD) use and how to effectively deliver services to address AOD use in humanitarian settings is limited. This study aimed to qualitatively explore the patterns of AOD use among Congolese refugees in Mantapala Refugee Settlement and members of the surrounding host community and identify potential appropriate intervention and implementation approaches to address AOD use disorders among conflict-affected populations.

METHODS

Fifty free listing interviews, 25 key informant interviews, and four focus group discussions were conducted among refugees, host community members, humanitarian implementing agency staff, and refugee incentive workers. These participants were selected based on their knowledge of AOD use and related problems in the settlement and the surrounding host community in northern Zambia.

RESULTS

Cannabis and home-brewed alcohol were the substances that were perceived to be most commonly used and have the greatest impact on the community. Participants reported that self-medication, boredom, and relief of daily stressors associated with lack of housing, safety, and employment were reasons that people used AODs. Participants recommended that programming include components to address the underlying causes of AOD use, such as livelihood activities. Stigma due to the criminalization of and societal ideals and religious beliefs regarding AOD use was identified as a substantial barrier to accessing and seeking treatment.

CONCLUSIONS

Our study's findings indicate the need for services to address AOD use in Mantapala Refugee Settlement. Interventions should consider the social and structural determinants of AOD use.

Drug use and access to drug dependency services for vulnerable migrants who use drugs in the European Union: Consensus statements and recommendations from civil society experts in Europe

BACKGROUND

The number of migrants in the European Union (EU) has been growing, including migrants at risk of using drugs. Little information is available on the actual drug use among first-generation migrants who use drugs in the EU, nor on their access to drug dependency services. This study aims to reach consensus among experts in the EU on the current situation regarding vulnerable migrants who use drugs in the EU and to develop a set of actionable recommendations.

METHODS

Between April and September 2022, a panel of 57 experts on migration and/or drug use, working in 24 countries, participated in a three-stage Delphi study to develop statements and recommendations about drug use and access to healthcare services for migrants who use drugs in the EU.

RESULTS

High levels of agreement were reached on the 20 statements (mean=98.0%) and 15 recommendations (mean=99.7%). The recommendations focus on four main topics; 1) increasing data availability and quality, to inform guidelines; 2) increasing the availability of drug dependency services for migrants, including screening for mental health issues and involving migrants who use drugs in the development of services; 3) eliminating country and service level barriers for accessing these services, as well as providing migrants who use drugs with suitable information, and combating stigma and discrimination; 4) the need for increased collaboration among and within EU countries regarding healthcare for migrants who use drugs, at the policy level as well as the service level, including civil society organisations, peer navigation and multilingual cultural mediators.

CONCLUSION

Policy action and increased collaboration are required by the EU as a whole and by individual EU member states, in addition to collaboration among healthcare providers and social welfare services, to increase access to healthcare services for migrants who use drugs.

Challenges in health care services for refugees in Cologne, Germany: A providers' perspective using a mixed-methods approach

Since the peak of refugees arriving in Germany in 2015, existing health care structures have faced major challenges. The city of Cologne developed ad-hoc new structures to address these challenges, including a separate department for refugee medicine. We examine the processes of health care provision and perceived challenges in the health care of refugees in Cologne. We used a mixed-methods approach using 20 semi-structured interviews and analyzed descriptively a database including 353 datasets with socio-demographic, health-related and resource-related information to link with the results of qualitative data. Our qualitative data revealed several challenges in providing health care to refugees. Challenges included receiving approval of health care services and medical aids by the municipality, communication and cooperation between the actors in care of refugees, undersupplies in mental health care and addictive disorders as well as improper housing conditions for refugees with mental health issues, psychiatric disorders or elderly persons. Quantitative data confirmed the challenges in approving health care services and medical aids, but no valid statement could be made about communication and cooperation. Undersupplies for mental health issues were confirmed, the gap for treatment of addictive disorders shows a divergence within the database. Improper housing conditions for mentally ill persons were reflected, for elderly persons this did not appear in data. In conclusion, analyzing the challenges in care can stimulate necessary changes to improve health services for refugees locally, while others are beyond the control of the local authority and require legislative and political action.

A systematic review of qualitative research on substance use among refugees

AIMS

To evaluate qualitative research on substance use and substance use disorders (SUDs) among refugees in terms of practitioners' and substance users' attitudes, beliefs and experiences.

METHODS

Six medical, allied health and social sciences databases (EBSCO, PubMed, ScienceDirect, Web of Science, Scholar and the Cochrane Library) were systematically searched in a time frame between January and April 2021 to identify original peer-reviewed articles describing qualitative findings related to substance use among refugees (alcohol, illicit drugs, tobacco and prescription drugs). Study selection, critical appraisal and detailed extraction were performed via the Joanna Briggs Institute Database of Systematic Reviews and Implementation Reports according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Systematic Reviews (PRISMA) (2018). Three independent reviewers selected the relevant abstracts and articles. Synthesis of the evidence identified prominent themes relating to the context and consequences of substance use.

RESULTS

Twenty-six studies were included in this review. Twenty-three studies applied qualitative methods and three applied mixed methods. Synthesis of the evidence from the included studies resulted in four main findings: there is a considerable susceptibility of refugees to substance use and SUDs; the harmful consequences of substance use are complicated by the social insecurities of refugees; there are rather high barriers to treatment and health facilities for refugees in many host countries; and there is a strong need to improve effective access to treatment, interventions and prevention approaches.

CONCLUSIONS

Refugees are at high risk for substance use and substance use disorders and often face high barriers to treatment and interventions in host countries.

Substance (mis)use among refugees as a matter of social ecology: insights into a multi-site rapid assessment in Germany

BACKGROUND

Previous research concluded that substance (mis)use is increasing among forcibly displaced populations. Nevertheless, little research has been conducted within a social ecological framework aimed at identifying and understanding the factors affecting substance (mis)use embedded in the post-migration context in high-income countries. The present study aims to develop an understanding of the links and underlying mechanisms between refugees' social ecological determinants and substance (mis)using behavior.

METHODS

Rapid assessments (RAs), including 108 semi-structured interviews and 10 focus group discussions with key persons from various professional, and personal backgrounds, were carried out in German urban and rural areas. The RA approach of interviewing key persons and not solely refugees that (mis)use substances allowed us to gather multi-perspective knowledge on this sensitive topic. Qualitative content analysis was applied, aiming at identifying determinants of substance (mis)use embedded in the post-migration context of refugees and understanding the underlying mechanisms.

RESULTS

One main result of the data suggests that the link between refugees' countries of origin and their post-migration substance (mis)use is not as direct as often assumed. It is observed that refugees' prospects and opportunities in receiving countries (e.g., work permits) undermine this commonly reproduced link. Further determinants are related to living conditions in German refugee shelters and social relations with peers and families. The influence of refugees' living conditions can be summarized as potentially increasing substance availability and distress, whereas family separation produces a loss of control and responsibility, increasing the risk for substance (mis)use. Peers' influence on substance (mis)use was reported to reflect a search for a sense of belonging.

CONCLUSIONS

Given that refugees who (mis)use substances have limited to no control over the factors identified in our study to be associated with substance (mis)use, common treatment and prevention approaches are challenged. Furthermore, we recommend aiming for a holistic comprehension of refugees' substance (mis)use by expanding the focus beyond individuals to the social ecological context in any attempt, including prevention, treatment, research, and policy.

Addressing the Mental Health Challenges of Refugees-A Regional Network-Based Approach in Middle Hesse Germany

Refugees constitute a vulnerable group with an increased risk of developing trauma-related disorders. From a clinician's integrative perspective, navigating the detrimental impact of the social, economic, structural, and political factors on the mental health of refugees is a daily experience. Therefore, a collective effort must be made to reduce health inequities. The authors developed a treatment concept which provides broader care structures within a scientific practitioner's approach. The resulting "Trauma Network" addresses the structural challenges for refugees in Middle Hesse. Accompanying research provided a sound basis for further discussions with policy-makers to improve the situation for refugees in the short- and long-term.

Alcohol use among Congolese Babembe male refugees in Tarrant County: A qualitative study

Background

Refugees are at high risk of alcohol abuse due to experiences in their country of origin, transit camps, and in host countries. Congolese have been the largest group of refugees resettled in the US since 2016 and Babembe represent one of the largest Congolese refugee sub-groups. There is a growing body of literature highlighting substance abuse among refugees resettled in the US, but little is known about Congolese Babembe. This study aimed to explore factors and practices contributing to alcohol abuse among Congolese Babembe refugees.

Methods

A qualitative research design employing a narrative inquiry approach was used in this study. One focus group discussion was conducted with a semi-structured guide in February 2020.A total of 19 hard-to-reach male refugee participants were recruited through snowball sampling. Audio recordings were translated and transcribed before a thematic content analysis was conducted using Nvivo 10.

Results

The main themes arose in the focus group analysis. First, the role of war, trauma, and migration in the onset of alcohol abuse in a community that once limited alcohol use to only older men for socialization. Second, refugees viewed alcohol abuse in their community as a result of post- resettlement cultural loss. Third, refugees perceived alcohol as serving a purpose to help cope with stressful conditions in the US and bad news received from loved ones in Africa. Further analysis shows the role of interactions with armed forces and other cultures during war and migration contributed to the adoption of alcohol abuse behavior.

Conclusion

Findings from this study suggest that factors contributing to alcohol abuse among Congolese Babembe refugees include personal traumatic experiences, loss of cultural identity, and conducive conditions in the host country. Understanding these factors can guide the development of appropriate interventions to prevent alcohol abuse in this vulnerable community. Further research is needed to include Babembe women’s perspectives.

STARC-SUD - Adaptation of a Transdiagnostic Intervention for Refugees With Substance Use Disorders

Background

Refugees often suffer from multiple mental health problems, which transdiagnostic interventions can address. STARC (Skills-Training of Affect Regulation - A Culture-sensitive Approach) is a culturally sensitive transdiagnostic group intervention that has been developed for refugees to improve affect regulation. In refugees with substance use disorders (SUD), the consideration of SUD-specific elements might improve the acceptance and effectiveness of such an intervention. We aimed to adapt the STARC program for refugees with SUD in a culturally sensitive way.

Method

The conceptual framework of Heim and Kohrt (2019) was used to culturally sensitively adapt the STARC program to the needs of Syrian refugees with SUD. The results of five focus group discussions with refugees on cultural concepts of SUD and their treatment informed the adaption. An expert group suggested adaptions and decided by consensus on their implementation. Two pilot groups were conducted with the adapted STARC-SUD program. Interviews with the therapists of these pilot groups informed further adaption.

Results

The concepts related to SUD identified in focus groups and therapists' interviews that differed from Western concepts were integrated into the STARC intervention.

Discussion

Further studies should assess the acceptance and effectiveness of the culturally sensitive STARC-SUD program for refugees with SUD.

Priorities for addressing substance use disorder in humanitarian settings

Background

Populations affected by humanitarian emergencies are vulnerable to substance (alcohol and other drug) use disorders, yet treatment and prevention services are scarce. Delivering substance use disorder treatment services in humanitarian settings is hampered by limited guidance around the preparation, implementation, and evaluation of substance use disorder treatment programs. This study aims to identify and prioritize key gaps and opportunities for addressing substance use disorder in humanitarian settings.

Methods

UNODC convened a consultation meeting (n = 110) in coordination with UNHCR and WHO and administered an online survey (n = 34) to, thirteen program administrators and policymakers, eleven service providers, nine researchers, and one person with lived experience to explore best practices and challenges to addressing substance use disorder in diverse populations and contexts. Participants presented best practices for addressing substance use disorder, identified and ranked challenges and opportunities for improving the delivery of substance use disorder treatment interventions, and provided recommendations for guidelines that would facilitate the delivery of substance use disorder treatment services in humanitarian emergencies.

Results

Participants agreed on key principles for delivering substance use disorder treatment in humanitarian settings that centered on community engagement and building trust, integrated service delivery models, reducing stigma, considering culture and context in service delivery, and an ethical ‘do no harm’ approach. Specific gaps in knowledge that precluded the delivery of appropriate substance use disorder treatment include limited knowledge of the burden and patterns of substance use in humanitarian settings, the effectiveness of substance use disorder treatment services in humanitarian settings, and strategies for adapting and implementing interventions for a given population and humanitarian context. Participants emphasized the need to strengthen awareness and commitment related to the burden of substance use disorder treatment interventions among communities, practitioners, and policymakers in humanitarian settings.

Conclusions

Results from this consultation process highlight existing gaps in knowledge related to the epidemiology and treatment of substance use disorders in humanitarian emergencies. Epidemiological, intervention, and implementation research as well as operational guidance are needed to fill these gaps and improve access to substance use treatment services in humanitarian settings.
