The Burden of Drug Abuse in Nigeria: A Scoping Review of Epidemiological Studies and Drug Laws

Hepatitis B virus infection among illegal drug users in Enugu State, Nigeria: prevalence, immune status, and related risk factors

INTRODUCTION

Hepatitis B virus infection poses a global health challenge, particularly in low- and middle-income African countries. Illicit drug use exacerbates the problem, with drug users having a higher HBV infection risk and maintaining a quiet transmission pool. This study aimed to determine HBV infection prevalence, immune status, and risk factors among illegal drug users in Enugu State, Nigeria.

MATERIALS AND METHODS

A cross-sectional study was conducted in Enugu State, using privileged access interviewer methods to enroll drug users. Pre-tested structured questionnaires were administered after informed consent was obtained. Blood samples were tested for HBsAg, HBsAb, HBeAg, HBeAb, and HBcAb using immunochromatographic rapid test kits. Statistical analysis was performed using SPSS version 25.

RESULTS

One hundred drug users were recruited into the study. Overall, 7% of the drug users had HBV infection. 61% were found to be susceptible to HBV infection, 15% showed serological evidence of immunity from HBV vaccination and 1% developed natural immunity from HBV exposure. Significant risk factors for HBV infection were age less than 20 years, young age (≤ 20 years) at drug initiation, being single, injecting drugs more than or equal to 20 times per month and injecting with used syringes.

CONCLUSION

This study shows high intermediate endemicity of HBV infection among drug users, low vaccination uptake, and high susceptibility to HBV infection. This calls for the urgent inclusion of drug users in national HBV vaccination campaigns and the adoption of the World Health Organization's recommendations on the prevention of viral hepatitis among people who inject drugs.

Adverse childhood experiences, individual-level risk and protective factors, and recent drug use in a community sample of Nigerian women

Adverse childhood experiences (ACEs) are associated with a wide range of health problems and health-compromising behaviors, including drug use, but are understudied in sub-Saharan Africa. Further, some data suggest that some types of ACEs are more strongly associated with outcomes than others. We investigated associations between different types of ACEs and recent drug use among 2,011 women living in Katsina State, Nigeria. This community-based survey included questions on ACE exposure, modifiable individual-level risk and promotive factors, and past-year drug use. Tobacco, cannabis, and the nonmedical use of cough syrup with codeine and tramadol were the most frequently used drugs. Logistic regressions revealed that across most drugs, ACEs reflecting abuse, neglect, and household dysfunction, but not community violence, increased the likelihood of drug use, odds ratios (ORs) = 1.30-3.10. Ease of access to drugs, ORs = 1.33-2.98, and personal religiosity, ORs = 1.19-2.27, also enhanced the risk of drug use, and higher depressive affect was associated with codeine, OR = 1.27, and tramadol use, ORs = 2.42. Practicing religious rites, ORs = 0.38-0.70; disapproval of drug use, ORs = 0.36-0.57; and perceived harm from drug use, ORs = 0.54-0.71, reduced the likelihood of drug use. Efforts to prevent abuse, neglect, and household dysfunction; reduce access to drugs; treat depression; and increase disapproval and harm associated with drug use may reduce drug use in the context of ACE exposure.

E-cigarettes in Nigeria: A scoping review of evidence

Background and Aims

E-cigarettes will continue to be a public health issue in Nigeria. To curb the growing menace of the e-cigarette use in Nigeria through evidence-based approach, it is crucial to first map the empirical research landscape of e-cigarettes in Nigeria. No known study has mapped the existing empirical evidence and gaps concerning e-cigarettes in Nigeria; hence, this scoping review was conducted.

Methods

This scoping review adopted the research design by Arksey and O'Malley. Four databases (PubMed, SCOPUS, CINAHL Complete, and APA PsycINFO) were searched to retrieve literature on e-cigarettes in Nigeria. With the aid of Rayyan web application, all retrieved literature were deduplicated and screened based on the review's eligibility criteria. Only those peer-reviewed journal papers meeting the inclusion criteria were included in the review. Relevant data from the included papers were charted, collated, and summarized.

Results

A total of six papers were included in this review. The reviewed papers reported a lifetime prevalence of e-cigarette use (or vaping) ranging from 5.8% to 19.8%, with a current e-cigarette use prevalence of 11.8%, among different population groups in Nigeria. The major determinants of e-cigarette use, as reported in these articles, include being a youth, having a health condition, severe anxiety, tobacco use, peer influence, and current alcohol use. Dry mouth and oral lesions (gingival inflammation and oral ulcers) were also identified to be the medical conditions associated with e-cigarette use in Nigeria. Lastly, one of the included papers identified a lack of clear regulation on e-cigarettes in Nigeria.

Conclusion

There is an urgent need for more scientific investigations on the sociodemographic, economic, health, and regulatory landscape of e-cigarettes in Nigeria, as robust empirical evidence is needed for the effective planning, implementation, and evaluation of evidence-based policies and interventions on e-cigarettes control and regulation in Nigeria.

Effect of HIV/AIDS on labour productivity and the moderating role of literacy rate: A panel study of Africa and its sub-regions

This study examined the effect of human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) on labour productivity in Africa and its sub-regions while controlling for the moderating effect of literacy rate. The study used the system Generalised Method of Moment estimation technique and annual panel data from 2010 to 2020 for 53 African economies. Labour productivity and literacy rate were measured by the ratio of gross domestic product to total employment and gross secondary school enrolment respectively. The results indicate that HIV/AIDS retards labour productivity, and that literacy rate can ease this depressing effect of HIV/AIDS in Africa. The sub-regional differences in Africa obtained in this study revealed that the depressing effect of HIV/AIDS on labour productivity is highest in Southern Africa and lowest in Northern and Central Africa. Interestingly, the study also established that per capita health expenditure, per capita income, gross capital formation, and information and communications technology are important drivers of labour productivity in Africa. The study, therefore, concludes that there is need for governments and other stakeholders to help to increase school enrolment and improve the quality of the content of education curriculum in Africa to increase the awareness of HIV/AIDS, especially as it relates to its channels of transmission like unprofessional blood transfusion, unprotected sexual activity, and genital mutilation, among others.

Exploring the operations of itinerant medicine sellers within urban bus terminals in Kumasi, Ghana

This paper explores Itinerant Medicine Sellers' (IMSs) operations at loading bays within bus terminals in the Kumasi metropolis. The paper examines how the sellers negotiated access into the loading bays, how they marketed their medicines, where they sourced their medicines from, and the challenges they faced. An exploratory qualitative survey design was adopted for the study. Through convenience sampling, 18 IMSs operating within the bus terminals in the Kumasi metropolis participated in this study. In-depth interviews were conducted, audio-recorded and transcribed. The transcripts were thematically analysed. The study found that these hawkers negotiated access to the loading bays through multiple informal gatekeepers and employed direct customer engagement in marketing their medicines. It was further revealed that the IMSs sourced their medicines from both formal and informal sources for different reasons, such as affordability and informality of medicines acquisition. The participants operated outside government-prescribed regulations and faced challenges of low capital and sales revenue, poor reception by prospective clients, and government clampdown. The study concludes that medicine hawking is an illegal livelihood strategy and a public health concern. As a phenomenon outside government's policy guidelines, it is recommended that government intensifies its clampdown activities on these hawkers and engage in public health education on the negative implications of accessing medicines from these IMSs.

Associations between mental health challenges, sexual activity, alcohol consumption, use of other psychoactive substances and use of COVID-19 preventive measures during the first wave of the COVID-19 pandemic by adults in Nigeria

BACKGROUND

The aims of this study were to assess: 1) the associations among sexual activity, alcohol consumption, use of other psychoactive substances and mental health during the COVID-19 pandemic; and 2) the associations between COVID-19 preventive measures, alcohol consumption and use of psychoactive substances.

METHODS

This was a secondary analysis of data collected from adults in Nigeria between July and December 2020. The variables extracted included change in sexual activity, alcohol consumption and use of other psychoactive substances, COVID-19 preventive behaviors (wearing face masks, washing hands, physical distancing), anxiety, depression, post-traumatic stress disorder (PTSD) and sociodemographic variables (age, sex, education, HIV status, employment status). Multivariable logistic regressions were conducted. A model was run to regress depression, anxiety, PTSD, increased alcohol consumption, and increased use of other psychoactive substances, on increased sexual activity. In separate models, anxiety, depression, and PTSD were regressed on increased alcohol consumption and on increased use of other psychoactive substances. Finally, three models were constructed to determine the associations between increased alcohol consumption and increased use of other psychoactive substances on three separate COVID-19 preventive behaviors. All models were adjusted for sociodemographic variables.

RESULTS

Increased alcohol consumption (AOR:2.19) and increased use of other psychoactive substances (AOR: 3.71) were significantly associated with higher odds of increased sexual activity. Depression was associated with significantly higher odds of increased alcohol consumption (AOR:1.71) and increased use of other psychoactive substances (AOR:3.21). Increased alcohol consumption was associated with significantly lower odds of physical distancing (AOR:0.59).

CONCLUSION

There was a complex inter-relationship between mental health, sexual health, increased use of psychoactive substances. The consumption of alcohol also affected compliance with physical distancing. Further studies are needed to understand the observed relationships.

Bilateral Self-enucleation of the Eyes: Case Report and Literature Review

Self-removal of the eyeball is an extreme form of self-harm, which is rare especially in a society ill-disposed to self-maiming. We report the case of a 75-year old man who plucked out his own two eyes in obedience to a voice urging him to do so. According to his wife, the patient had been exhibiting symptoms suggestive of a psychiatric disorder just before the incident. But this was overlooked. This case report draws attention to the devastating ophthalmic consequences of neglected psychiatric disorders in the elderly. We recommend greater attention to the mental health of the elderly. Prevention and management of auto-enucleation requires a collaboration between psychiatrists and ophthalmologists.

Substance use and substance use disorders in Africa: An epidemiological approach to the review of existing literature

The relationship between man and substances that have abuse potentials, and whose use has been associated with the development or progression of substance use disorders has continued to evolve in terms of geography, economic implications, and time. History shows that local plants with psychoactive constituents can get exported worldwide through global travel, commerce, or even conquest. Time and globalization also change people’s relationship with substances of abuse; hence, an area that was initially alien to certain substances might evolve to becoming a trafficking hub, and then a destination. A case in point is Africa where a rapidly increasing prevalence of substance use/abuse and substance use disorder among adolescents and young adults is putting enormous strain on the economy, healthcare system, and society at large. However, there appears to be a paucity of scientific literature and data on the epidemiology, risk assessment, and contributing factors to substance use and the development of substance use disorders across Africa. In this narrative review, we examine extant literature (PubMed, Google scholar, Medline) for information on the prevalence, trends, and influencers of substance use and the development of substance use disorders. This is with a view of understanding the determinants of substance use and factors that influence the development of substance use disorders in the region, and how this information can be channeled towards developing a comprehensive intervention and treatment program.

Factors that influence pharmacists' efforts in addressing substance use in Nigeria: An exploratory study

Introduction

Substance use is a major global public health problem. Over the years, the burden of substance use has increased worldwide, with Nigeria having a prevalence that is substantially above the global average. Tackling this challenge requires a collaborative effort between different health professionals. Despite the critical roles pharmacists could play in substance use prevention and management, exploration of pharmacists' role in mitigating substance use in society has received limited attention in most sub-Saharan countries. In this study, we explored the experiences of pharmacists in substance use prevention and management.

Methods

We conducted semi-structured interviews to explore pharmacists' perceptions of their roles in the prevention and management of substance use in Nigeria. Following data transcription, we conducted a thematic content analysis.

Results

The four major themes that emerged included 1) the extent of pharmacists' involvement in the decision-making process for addressing substance use, 2) factors that influence pharmacists efforts in addressing substance use in Nigeria, 3) how to improve rational prescribing practices and, 4) capacity building to enhance pharmacists participation in addressing substance use.

Conclusion

Pharmacists have the opportunity to play critical roles in the prevention and management of substance use, but several individual and systemic challenges limit their full potential. Addressing these challenges is crucial in increasing pharmacists' participation in preventing and managing substance use.

The Impact of Consumers' Loneliness and Boredom on Purchase Intention in Live Commerce During COVID-19: Telepresence as a Mediator

This paper examines the relationship between consumer loneliness, boredom, telepresence, influencer-brand image congruence and purchase intention by investigating consumers of live commerce during the COVID-19 period. With the help of an online survey website, survey data was gathered on 550 Chinese customers who experienced live commerce shopping in China. Although previous studies have shown that consumer boredom and loneliness have an impact on purchase intention, the mechanism of influence remains unclear. As a result, additional research is needed to study the link between boredom and loneliness and customer purchase intention. Consumers' purchase intention was influenced by their feelings of loneliness and boredom. Telepresence played a mediating role in the impact of loneliness and boredom on purchase intention. Influencer-brand image congruence played a moderating role in the impact of consumers' boredom on purchase intention. The study results contribute to the research of factors impacting consumers' purchase intention. In addition, this study can help live commerce merchants better understand the impact factors of consumers' purchase intention and contribute to the development of live commerce.

Integrating mental health into primary care: evaluation of the Health Action for Psychiatric Problems In Nigeria including Epilepsy and SubstanceS (HAPPINESS) pilot project

Background

The Health Action for Psychiatric Problems In Nigeria including Epilepsy and SubstanceS (HAPPINESS) project trains non-specialist and primary health care workers in Imo State, Nigeria. This project adapted the World Health Organization’s Mental Health Gap Action Programme-Intervention Guide (mhGAP-IG), emphasizing stigma reduction among trainees. This convergent mixed-methods proof-of-concept study evaluates the HAPPINESS pilot project mhGAP-IG training’s impact on mental illness stigma among trainees and barriers, facilitators, and opportunities to consider for project improvement.

Methods

Trainees (n = 13) completed a 43-item questionnaire before and after their 5-day training to assess perceptions of mental disorders and attitudes towards people with mental illness. These responses were analyzed using paired-sample t-tests for four subscales of the questionnaire: acceptance of socializing with people with mental illness, normalizing activities and relationships with people with mental illness, supernatural causation of mental illness, and endorsement of a biopsychosocial approach to mental illness. Semi-structured key informant interviews (n = 11) with trainees, trainers, and local health officials who participated in or supported the HAPPINESS project were thematically analyzed to understand their experiences and perspectives of the project’s barriers, facilitators, and opportunities.

Results

Trainees showed significant improvements on socializing, normalizing, and supernatural causation subscales of the stigma questionnaire (p < 0.05). No significant effect was seen on the biopsychosocial subscale; however, evidence of biopsychosocial beliefs was found in interview responses. Key informant interviews revealed that the HAPPINESS project enhanced trainees’ diagnostic and treatment abilities, mental health awareness, and empathy towards patients. Misinformation, stigma, inadequate funding, and lack of road access to clinics were identified as barriers to mental health care integration into general care in Imo State. Respondents also suggested ways that the HAPPINESS project could be improved and expanded in the future.

Conclusions

This study adds to the limited evidence on the implementation of mhGAP-IG in Nigeria. Using mixed methods, it evaluates how mhGAP-IG can impact perceptions and knowledge of stigma among primary care trainees. It also highlights barriers, facilitators, and opportunities to consider for project growth. Future efforts should focus on clinical support, supervision, health outcomes, as well as scaling up and assessing the cost-effectiveness of the HAPPINESS project intervention.

Using a Syndemics Framework to Understand How Substance Use Contributes to Morbidity and Mortality among People Living with HIV in Africa: A Call to Action

Substance use is increasing throughout Africa, with the prevalence of alcohol, tobacco, cannabis, and other substance use varying regionally. Concurrently, sub-Saharan Africa bears the world’s largest HIV burden, with 71% of people living with HIV (PWH) living in Africa. Problematic alcohol, tobacco, and other substance use among PWH is associated with multiple vulnerabilities comprising complex behavioral, physiological, and psychological pathways that include high-risk behaviors (e.g., sexual risk-taking), HIV disease progression, and mental health problems, all of which contribute to nonadherence to antiretroviral therapy. Physiologically, severe substance use disorders are associated with increased levels of biological markers of inflammation; these, in turn, are linked to increased mortality among PWH. The biological mechanisms that underlie the increased risk of substance use among PWH remain unclear. Moreover, the biobehavioral mechanisms by which substance use contributes to adverse health outcomes are understudied in low- and middle-income countries (LMIC). Syndemic approaches to understanding the co-occurrence of substance use and HIV have largely been limited to high-income countries. We propose a syndemic coupling conceptual model to disentangle substance use from vulnerabilities to elucidate underlying disease risk for PWH. This interventionist perspective enables assessment of biobehavioral mechanisms and identifies malleable targets of intervention.

Mental health in Nigeria: A Neglected issue in Public Health

In Nigeria, the disparity between available healthcare services and need for mental health services is palpable. Although, the country has made significant advances on challenging public health problems, health-related policy development and legislation in trying to achieve health for all policy, there have been challenges with regards to mental health services including that of policy development and legislation, financing, research, training and integration of mental health care into primary health care. We consulted relevant publications, official document, policy statement, blueprints, working plans of the relevant organizations responsible for mental care and services locally and globally. We identify and highlight challenges faced in mental health services implementation and provide recommendations as way forward and call for urgent action to government, non-governmental organizations (NGOs), policy makers and legislatives which are urgently needed to reform and implement them for a better, accessible, and affordable mental health services for the mental well-being of the populace.

A Model for Predicting the Class of Illicit Drug Suspects and Offenders

In this study, the artificial neural network was deployed to develop a classification model for predicting the class of a drug-related suspect into either the drug peddler or non-drug peddler class. A dataset consisting of 262 observations on drug suspects and offenders in central Nigeria was used to train the model which uses parameters such as exhibit type, suspect’s age, exhibit weight, and suspect’s gender to predict the class of a suspect, with a predictive accuracy of 83%. The model sets the pace for the implementation of a full system for use at airports, seaports, police stations, and by security agents concerned with drug-related matters. The accurate classification of suspects and offenders will ensure a faster and correct reference to the sections of the drug law that correspond to a particular offence for appropriate actions such as prosecution or rehabilitation.
