CHAPTER ONE

INTRODUCTION

 Background to the Study Psychoactive Substance use and dependence cause a significant burden to the individuals and societies throughout the world. The World Health Report (2010) indicated that 8.9% of the total burden of disease comes from the use of psychoactive substances. The report showed that tobacco accounted for 4.1%, alcohol 4%, and illicit drugs 0.8% of the burden of disease in 2010. Much of the burden attributable to substance use and dependence is the result of a wide variety of health and social problems. Data from the (World Health Organization, 2011) show large-scale seizures of cocaine, heroin, cannabis and amphetamine-type stimulants in different parts of the world. Availability of cocaine, heroin and cannabis depends on the level of cultivation in source countries and on the success or failure of trafficking organizations. However, even with increased levels of law enforcement activities, there always seems to be enough available to users. According to (UNODC, 2011) estimates show that about 200 million people make illicit use of one type of illicit substance or another. Psychoactive substance use is a social problem that has spread and increased rapidly in educational institutions especially among secondary school students (Neeraja, 2011). This social problem is considered an issue of serious concern as it adversely affects the lives and performance of students involved as well as the harmonious functioning of the entire structure of the society. Use of psychoactive drugs and other associated problems are inimical to the survival and effective functioning of human societies. A significant number of untimely deaths and accidents have been linked to the activities of persons under the influence of one psychoactive drug or the other (Shelly, 2010).Drug abuse is viewed by different authorities in various forms. Neeraja (2011) defined substance abuse as the dependence on a drug or other chemical substances leading to the effect that are detrimental to the individual’s physical and mental health or the welfare of others. According to Smelzer, Bare, Hinkle, and Cheever (2008) substance abuse is a maladaptive pattern of drug use that causes physical and emotional harm with the potential for disruption of daily life. From these definitions, it can be deduced that substance abuse is the misuse of one or more drugs which could be prescribed by a health practitioner with the intention to alter the way one feels, thinks or behaves and it is associated with consequences which include physical and emotional harm to the person.The African Symposium (2010) viewed substance abuse as the improper use or application of drugs by a person without proper knowledge of the drugs and without due prescription from a qualified medical practitioner. This definition focuses on psychoactive drugs. All drugs can be abused to an extent that it turns into addiction when the drug user is unable to stop the use of the drugs despite the harmful effects on the user’s social, personal and economic lives. The problem of substance abuse is so grave that though it was originally conceived as the problem of a ‘select few’, it has extended beyond the usual characteristics of abusers being males, adults and urban based people, to now include females, youngsters and rural dwellers (Rocha, 2009). These abusers erroneously believe that drugs enhance their performance, put them in good mood etc. The accompanying problems of this act constitute a major threat to the well-being of the society (Ajala, 2009).
