This research centers on the influence of drug abuse, theories of causes, signs and symptoms, effects, on the mental ability of undergraduate students in higher institutions. Drug abuse and dependence otherwise known as substance or chemical abuse is a disorder that is characterized by a destructive pattern of applying drugs thereby leading to significant problems or disorder. This devastating problem cuts across every strata of human society but mostly rampant among the adolescence. This study, “The causes of drug abuse and its effects among secondary school students” is written to appraise the effects of drug abuse, dependence and how it affects the academic performance and intellectual capability of the students in secondary schools. The research concludes that the mental ability of students have been so poor due to the effects of drug abuse and addiction hence recommends that public sensitization should be carried out periodically on the dangers of drug abuse while the regulatory bodies be strengthened to carry out their functions effectively so as to reduce the trend especially in tertiary institutions.
1.1 BACKGROUND OF THE STUDY
Drug abuse being, an extreme desire to obtain and use increasing amount of one or more substance, this include alcohol, nicotine, marijuana, cigarettes, codeine and other substances which are harmful to the health of the individual. When considering drug abuse one should be able to differentiate it from drugs dependence or drugs addiction, which is the physical dependence on drugs to function. Drug abuse is a deliberate in-take of drugs for purposes other than its intended purpose without the supervision of a physician or a medical practitioner while drug addiction is the continuous uncontrolled, compulsive use of a drug not only to include intoxication but also to avoid the tortures of withdrawal. Despite the unrelenting effort of individuals, agencies, mass media and the government at different levels against drug abuse, the prevalent practice among undergraduate students in higher institution, and even adults in the community has not reduced but on the increase geometrically.
According to Ajayi and Ayodele (2002), drug abuse is the wrong use or inappropriate use of chemical substances that are capable of changing functions of cells in the body. Bayer, as cited in Egbochuku and Akerele (2007), saw stimulants, which are substances that cause an increase in the activity of an organ in the body, as chemicals that excite certain activities of the central nervous system. Ajayi and Ekundayo (2010) also saw drug abuse as over-dependence and misuse of one particular drug with or without a prior medical diagnosis from qualified health practitioners.
Scholars tends to question who falls victims to drug abuse, which brought the conclusion that anyone can be a victim of drug abuse irrespective of age, social groups and genders.
Drug abuse is a social problem that has spread like a wild fire across our educational institutions especially among our higher institution in Nigeria. In higher institution today, this social mal adaptation 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 society. Drug abuse and other associated problems are inimical to the survival and effective functioning of human societies. A significant number of health hazards, untimely deaths, and accidents have been linked with the activities of persons under the influence of one drug or the other.
Many people have defined drug abuse in different ways neglecting it actual causes. In medicine, drugs refer to any substance with the potential to prevent or cure diseases. Drugs can be legal or illegal. Drug abuse refers to non-medical use of drugs. A substance is considered abused if it is deliberately used to induce physiological or psychological effects or both for purpose other than therapeutic ones and when the use contributed to health risks or some combinations of these.
The World Health Organization (WHO), defines drug as any substance other than those required for maintenance of normal health, which when taken into the living organism, may modify one or more of its functions (Ghodse, 2003).
According to a United Nations Office on Drugs and Crime (UNODC) Report (2005), about 200 million people, or 5 percent of the world’s population age between 15 and 65 have used drugs at least once in the last 12 months. Likewise, according to the World Drug (2005) reported that, the use of illicit drugs in all Nations has increased in recent years. The report goes on to note that the increasing availability of a variety of drugs to an ever widening socio-economic spectrum of consumers is disconcerting, although the main problem at the global level continues to be opiates (notably heroine) followed by cocaine. For most of Europe and Asia, opiates accounted for 62 percent of all drug treatment sought in 2003. While 3.3 to 4.1 percent of the global population admits to consuming drugs, the most worrisome trend for the UNDCP Executive Director is the younger and ages at which people are becoming addicted. In Pakistan for example, the share of those who started heroine use at 15-20 years of age has doubled to almost 24 percent. A survey in the Czech Republic showed that 37 percent of new drug users were youths between 18 and 25 years old. In Nigeria, drug use in particular heroin use is becoming a serious problem and nearly 6 percent of secondary and tertiary school students admit to having experimented with drugs.
Adewuya (2005) noted that alcohol is most widely used among young people. West and Graham (2005) also agreed that students, as a subset of the youth population, consume large quantities of alcohol, tobacco and other drugs. Ajake, Isangedihi and Bisong (2009) posited that premarital sexual practices and drug abuse constitute social ills that have been age-long problems in the secondary school system. Ajayi and Ekundayo (2010) equally confirmed that drug abuse has been identified as a serious constraint to effective teaching and learning process in the Nigerian educational system. Drug abuse, according to Ajayi and Ayodele (2002), is the wrong use or inappropriate use of chemical substances that are capable of changing functions of cells in the body. Bayer, as cited in Egbochuku and Akerele (2007), saw stimulants, which are substances that cause an increase in the activity of an organ in the body, as chemicals that excite certain activities of the central nervous system. Ajayi and Ekundayo (2010) also saw drug abuse as over-dependence and misuse of one particular drug with or without a prior medical diagnosis from qualified health practitioners. They further identified dangerous drugs like cocaine, Indian hemp (marijuana), heroin, tobacco, ephedrine, valium five and Chinese capsules as few among the drugs commonly abused by youths. Oshodi, Aina and Onajole (2010) reported that, despite worldwide concern and education about psychoactive substances, many adolescents have limited awareness of their adverse consequences. They further explained that curiosity, social pressure and peer group influence are noted to be primary reasons for substance misuse.
1.2 STATEMENT OF THE PROBLEM
Alcohol and cigarette are said to be legal around the globe, but these same substances led to the initiation of other more potent drugs like heroin and cocaine. Abuse of drugs has created several health issues and dangers in our schools today. Such as mental illness, cancer of the lungs, school drop-outs, cultism, gangsters, rape cases and even examination-malpractices and juvenile delinquency, arm robbery attacks, insurgency etc. The alarming rate of influence of drug and substance abuse in higher institution in Nigeria is very common and it effects are so numerous. This study, therefore, attempts to investigate the contributions of family background, peer groups and family cohesion to drug abuse in schools and the effects of drug abuse on mental ability of students in higher institution.
1.3 OBJECTIVE OF THE STUDY
The broad objective of the study is to examine the influence of drug and alcohol on mental ability of students in higher institution. The specific objectives include the following:
- To examine the influence of drug and alcohol on mental ability of students in higher institution
- To determine the effects of drug abuse among undergraduates in higher institutions in Nigeria.
- To ascertain if there is any significant difference in the causes of drug abuse between the male and female students
- To ascertain the relationship between drug abuse and drug addiction on mental ability of students in higher institution.
1.4 RESEARCH QUESTIONS
For the purpose of this study the following questions were raised by the researcher for the in depth study of this research work;
- What are the causes of drug abuse among undergraduates in higher institutions in Nigeria?
- What are the effects of drug abuse among undergraduates in higher institutions in Nigeria?
- What is the relationship between drug abuse and drug addiction on mental ability of students in higher institution?
- What are the impacts of drugs abuse on students’ academic achievement?
1.5 SIGNIFICANCE OF THE STUDY
This study will be of utmost benefits to students and school authority in higher institutions as it serves as a blue print in curtailing the dangers of drugs in universities. The study will be relevant to those who will want to carry out a similar research topic as it has contributed to the existing literature. Finally, the study will be relevance to the National Drug Law Enforcement Agency (NDLEA), NYSC Drug Free Club (DFC), and other relevant bodies in combating drug abuse and addiction on our schools and campuses.
1.6 SCOPE AND LIMITATION OF THE STUDY
This study examined the influence of drug abuse and alcohol on mental ability of students in higher institution in relation to their family background, family cohesion, peer group influence, and it effects on students’ academic performance. In the cause of the study, the researcher encounters some limitations which limited the scope of the study;
Time constraint: The researcher will simultaneously engage in this study with other academic work. This consequently will cut down on the time devoted for the research work.
Inadequate Materials: Scarcity of material is also another hindrance. The researcher finds it difficult to long hands in several required material which could contribute immensely to the success of this research work.
Financial constraint: Insufficient fund tends to impede the efficiency of the researcher in sourcing for the relevant materials, literature or information and in the process of data collection (internet, questionnaire and interview).
