Project – Prevalence and patterns of psycho active substance use among senior secondary school

CHAPTER ONE

INTRODUCTION

1.1 Background to the Study

Psychoactive substance use among adolescents has evolved into a pressing global public health concern, particularly in developing countries like Nigeria. Psychoactive substances refer to chemical compounds that, when consumed, can influence mental processes, such as perception, mood, consciousness, cognition, and behavior. Commonly abused substances include alcohol, tobacco, cannabis, cocaine, amphetamines, inhalants, and prescription medications such as opioids and sedatives. These substances can be legal, semi-legal, or illegal depending on the context, but all have the potential for misuse and dependence. According to the United Nations Office on Drugs and Crime (UNODC, 2018), the rise in substance use among adolescents is not only alarming but also has far-reaching implications for individual health and societal well-being.

Adolescence is a developmental phase characterized by rapid physical, emotional, and psychological changes, as well as increased curiosity and risk-taking behavior. It is often during this critical period that many individuals are first introduced to drugs and other psychoactive substances. Several factors, including peer pressure, poor parental supervision, stress, the desire for social acceptance, and exposure to media, contribute significantly to the initiation and continued use of drugs among adolescents. The school setting, in particular, is a primary social environment where such behaviors are observed and sometimes normalized (Adelekan & Ndom, 2020). For senior secondary school students, who are often on the verge of adulthood, the pressure to conform, succeed academically, and assert independence may drive them toward experimenting with substances.

In Nigeria, the challenge of adolescent substance abuse is compounded by socio-economic instability, porous drug regulation policies, and a lack of effective youth-focused mental health programs. Within educational institutions, particularly at the secondary school level, students have been reported to abuse readily accessible substances such as alcohol, cigarettes, and even pharmaceutical products like tramadol, rohypnol, and codeine-based cough syrups. This worrying trend has been exacerbated by the glamorization of drug use in music, movies, and on social media platforms, which portray drug use as a symbol of success, freedom, or rebellion. Without adequate education, guidance, and monitoring, students often fall victim to these misleading narratives, putting their academic and personal futures at risk.

Specifically, in Delta State—and more precisely in Warri South Local Government Area—there are growing concerns about the increasing prevalence of psychoactive substance use among secondary school students. Warri South is a vibrant and urbanized area marked by diverse social classes, rapid development, and industrial activities, particularly in the oil and gas sectors. These dynamics create both opportunities and challenges. While economic opportunities exist, issues like unemployment, poverty, crime, and social inequality persist. These challenges often drive young people toward drug use as a coping mechanism or escape from their realities. Reports from schools, community stakeholders, and health professionals suggest that substances such as cannabis, tramadol, and tobacco are becoming increasingly popular among secondary school students, many of whom begin using these substances as early as age 13 or 14 (Oshodi et al., 2019).

The consequences of psychoactive substance use among adolescents are severe and multifaceted. Academically, students who use drugs are more likely to experience declining performance, absenteeism, and eventual school dropout. Health-wise, substance use may lead to mental health issues such as depression, anxiety, and psychosis, as well as physical complications like liver damage, cardiovascular diseases, and overdose-related deaths. Socially, substance use increases the likelihood of antisocial behaviors, such as theft, violence, and risky sexual conduct. Moreover, early exposure to drugs can result in long-term addiction problems, further reducing a young person’s chance of living a healthy and productive life. These outcomes not only affect the individual student but also place a significant burden on families, schools, and the broader society.

Despite these growing concerns and anecdotal reports, there is a notable lack of comprehensive empirical data specifically focused on the prevalence and patterns of psychoactive substance use among senior secondary school students in Warri South. Most available studies have focused on major urban centers like Lagos, Abuja, and Port Harcourt, neglecting mid-sized cities that may have unique socio-economic and cultural factors influencing substance use. As such, there is a critical need for a study that explores the scope, trends, and correlates of psychoactive substance use within this specific context. This research aims to bridge that gap by generating evidence-based insights that can inform school-based interventions, public health campaigns, and policy reforms targeted at reducing substance use among students in Warri South Local Government Area.

1.2 Statement of the Problem

The abuse of psychoactive substances by adolescents, particularly those in senior secondary schools, has emerged as a serious threat to their academic success, mental health, and overall development. This growing trend of substance use among students has far-reaching implications, not only for the individuals involved but also for families, schools, and the broader society. Psychoactive substances such as tramadol, cannabis, codeine, and alcohol are increasingly being consumed by teenagers, sometimes openly, in school environments. These substances impair judgment, reduce concentration, and increase the likelihood of engaging in risky behaviors, all of which severely undermine students’ educational outcomes and future prospects.

In Warri South Local Government Area of Delta State, there are increasing anecdotal reports of psychoactive substance use among senior secondary school students. These include cases of truancy, violence, declining academic performance, and even confrontations with law enforcement. Teachers and parents frequently express concerns about the behavioral changes observed in students, which they attribute to substance abuse. However, despite these reports, there is limited empirical evidence to accurately quantify the problem or to analyze the specific substances being abused, their sources, patterns of usage, and the underlying social and environmental factors. This lack of concrete data has made it difficult to plan effective interventions or to hold students and enablers accountable.

Moreover, much of the existing research on adolescent substance use in Nigeria has focused on large metropolitan cities like Lagos, Abuja, and Port Harcourt. These studies often overlook smaller yet equally vulnerable regions such as Warri, which presents a unique set of socio-economic conditions that can influence drug use behavior. Warri South, characterized by industrial activity, youth unemployment, and varying levels of poverty, creates an enabling environment for the proliferation of psychoactive substances. The presence of slums, street gangs, and weak drug enforcement laws further compounds the problem, making students easy targets for drug dealers and peer pressure.

The absence of focused, localized research limits the ability of school administrators, community leaders, health professionals, and policymakers to respond effectively. Without accurate data, efforts to curb the problem are often based on assumptions or generalized approaches that may not address the specific drivers of substance use in Warri South. As a result, preventive education programs may fail to resonate with the students, while health and counseling services remain underutilized or misdirected. There is an urgent need for empirical studies that can uncover the depth, frequency, and patterns of substance use in this area.

Therefore, this study is necessary to explore and document the prevalence and usage patterns of psychoactive substances among senior secondary school students in Warri South LGA. By providing data-driven insights into the types of substances being abused, the demographic characteristics of users, and the environmental influences driving usage, the study aims to support the development of targeted interventions. The findings will also serve as a resource for educators, mental health practitioners, and policymakers to formulate policies and programs that are culturally relevant and practically effective in addressing this escalating issue.

1.3 Aim and Objectives of the Study

The aim of this study is to investigate the prevalence and patterns of psychoactive substance use among senior secondary school students in Warri South Local Government Area of Delta State, Nigeria. The specific objectives are to:

1. Determine the prevalence of psychoactive substance use among senior secondary school students.
2. Identify the common types of psychoactive substances used by the students.
3. Explore the patterns and frequency of psychoactive substance use.
4. Examine the socio-demographic and environmental factors associated with substance use among students.

1.4 Research Questions

The study will be guided by the following research questions:

1. What is the prevalence of psychoactive substance use among senior secondary school students in Warri South LGA?
2. What types of psychoactive substances are most commonly used by these students?
3. What are the usage patterns (e.g., frequency, context, peer influence) of substance use among students?
4. What socio-demographic and environmental factors are associated with substance use in this population?

1.5 Hypotheses of the Study

The following hypotheses will be tested in the study:

H₀: There is no significant relationship between students’ socio-demographic characteristics and their use of psychoactive substances.

H1: There is a significant relationship between students’ socio-demographic characteristics and their use of psychoactive substances.

1.6 Significance of the Study

This study is of great significance as it provides much-needed empirical data on the prevalence and patterns of psychoactive substance use among senior secondary school students in Warri South Local Government Area. Unlike larger cities such as Lagos and Abuja that have been the focus of numerous research efforts, Warri South remains relatively under-studied despite growing concerns over adolescent drug use in the area. By filling this knowledge gap, the study will offer a clearer picture of the scope of the problem, thereby guiding stakeholders toward more informed decision-making.

Secondly, the study is critical for school administrators, teachers, and guidance counselors who are often the first to observe signs of drug use in students. The insights gained from this research will enable educational stakeholders to identify at-risk students, understand the types of substances commonly used, and tailor intervention strategies to the unique challenges faced in the school environment. Early detection and timely intervention can significantly reduce the long-term negative impact of substance abuse on students’ academic performance and personal development.

In addition, parents and community leaders will benefit from the study’s findings by gaining a deeper understanding of the socio-cultural and environmental factors contributing to substance abuse. Many parents are unaware of the early warning signs of drug use or the subtle ways their children are influenced by peer pressure and social media. The study will provide them with practical knowledge and tools to engage their children in meaningful discussions and foster healthier, more protective home environments.

Health practitioners and mental health professionals will also find this study valuable, as it will offer data on the psychological and behavioral consequences of psychoactive substance use among adolescents. This will help in designing adolescent-focused health programs, counseling sessions, and rehabilitation services that address the specific needs of students in Warri South. Furthermore, non-governmental organizations (NGOs) and civil society groups can use the findings to support advocacy campaigns and community-based sensitization programs aimed at substance use prevention.

Moreover, this study will serve as a solid foundation for further academic and policy-oriented research on adolescent health and behavioral patterns in the region. It can stimulate more nuanced inquiries into related issues such as mental health, school safety, delinquency, and peer influence. By generating credible baseline data, the research will encourage scholars and institutions to expand the scope of research in Delta State and other less-researched regions.

Finally, the study aligns with the global commitment to achieving Sustainable Development Goal (SDG) 3, which emphasizes ensuring healthy lives and promoting well-being for all at all ages. By addressing adolescent substance abuse—a major public health threat—the research contributes to efforts to reduce premature mortality, combat substance use disorders, and strengthen preventive education. The findings may inform both local and national policy frameworks, leading to the development of more effective drug control laws, school health policies, and youth empowerment initiatives across Nigeria.

1.7 Scope of the Study

The study examines Prevalence and patterns of psycho active substance use among senior secondary school in Warri south local government area in Delta State, Nigeria. The study is limited to selected Secondary Schools in senior secondary school in Warri south local government area.

1.8 Operational Definition of Terms

Psychoactive Substances: Psychoactive substances are chemical compounds that exert their effects primarily by acting on the central nervous system. They alter normal brain function, thereby influencing a person’s perception, mood, consciousness, cognition, or behavior. These substances may be either legal, such as alcohol and tobacco, or illegal, such as cannabis, cocaine, heroin, and amphetamines. Some prescription medications like codeine, tramadol, and benzodiazepines can also become psychoactive substances when misused. The term is used in this study to refer to any such substance that is consumed by students for recreational or non-medical purposes.

Substance Use: This refers to the act of intentionally consuming psychoactive substances, whether legally or illegally, for purposes unrelated to medical treatment. It includes the use of drugs such as alcohol, cannabis, tramadol, inhalants, and other substances that affect mental and emotional functioning. In the context of this study, substance use focuses on non-medical usage by adolescents, particularly students in senior secondary schools, and is examined in terms of its prevalence, motivations, and consequences.

Prevalence: Prevalence is a statistical term used to describe the proportion or percentage of individuals in a defined population who have engaged in a particular behavior or condition at a given time. In this study, prevalence refers specifically to the number of senior secondary school students in Warri South Local Government Area who report using psychoactive substances within a certain time frame (e.g., past month, past year, or lifetime). Measuring prevalence helps to determine how widespread the problem is and to identify high-risk groups within the population.

Patterns of Use: Patterns of use refer to the specific ways in which psychoactive substances are consumed. This includes the types of substances used, the frequency (how often they are used), duration (how long the user has been using), context (social settings, peer influence, or stress-related scenarios), and method of administration (e.g., smoking, drinking, injecting). Understanding these patterns is essential for designing targeted interventions and helps to reveal whether substance use is experimental, occasional, or habitual.

Student: In the context of this research, a student refers to a young individual enrolled in an educational institution, particularly at the secondary school level. These students are typically between the ages of 13 and 19 years and are considered to be in a formative stage of development where peer influence, academic pressure, and identity formation are particularly strong. The term as used in this study focuses specifically on senior secondary school students who may be more susceptible to experimentation with drugs due to increased social exposure and limited supervision.

Secondary School: A secondary school is an educational institution that follows primary education and precedes tertiary or university education. In Nigeria, it typically includes Junior Secondary School (JSS 1–3) and Senior Secondary School (SSS 1–3). This study specifically focuses on students in Senior Secondary School, who are generally in their mid- to late-teenage years. These students are at a critical stage of adolescence where they may encounter increased academic stress, social experimentation, and vulnerability to negative peer influences, including substance use.
