A drug refers to a substance that could bring about a change in the biological function
through its chemical actions (Okoye, 2001). It is also considered as a substance that modifies
perceptions, cognition, mood, behaviour and general body functions (Balogun, 2006). They could thus, be considered as chemical modifiers of the living tissues that could bring about physiological
and behavioural changes (Nnachi, 2007)
Drug abuse is a major public health problem all over the world (UNODC) (2005). The use
and abuse of drugs by adolescents have become one of the most disturbing health related
phenomena in Nigeria and other parts of the world (NDLEA; 1997).Several school going
adolescents experience mental health programme, either temporarily or for a long period of time.
Some become insane, maladjusted to school situations and eventually drop out of school.
According to Fawa (2003), “Drug is defined as any substance, which is used for treatment
or prevention of a disease in man and animals. Drug alters the body functions either positively or
otherwise depending on the body composition of the user, the type of drug used, the amount used
and whether used singly or with other drugs at the same time”.
NAFDAC (2000) as cited by Haladu(2003) explained the term drug abuse as excessive and
persistent self-administration of a drug without regard to the medically or culturally accepted
patterns. It could also be viewed as the use of a drug to the extent that it interferes with the health
and social function of an individual.
World Book Encyclopedia (2004) defined drug abuse as the
non-medical use of a drug that interferes with a healthy and productive life Manbe (2008) defined
drug abuse as the excessive, maladaptive or addictive use of drugs for non-medical purpose
Types of Drugs Abused in Nigeria
In Nigeria, the most common types of abused drugs according to NAFDAC (2000) as cited
by Haladu (2003) are categorized as follows:-
1.
Stimulants: These are substances that directly act and stimulate the central nervous system.
Users at the initial stage experience pleasant effects such as energy increase. The major
source of these comes from caffeine substance.
2.
Hallucinogens’ :These are drugs that alter the sensory processing unit in the brain. Thus,
producing distorted perception, feeling of anxiety and euphoria, sadness and inner joy,
they normally come from marijuana, LSD etc.
3.
Narcotics: These drugs relive pains, induce sleeping and they are addictive. They are found
in heroin, codeine, opium etc.
4.
Sedatives :These drugs are among the most widely used and abused. This is largely due to
the belief that they relieve stress and anxiety, and some of them induce sleep, ease tension,
cause relaxation or help users to forget their problems. They are sourced from valium,
alcohol, promotazine, chloroform.
5.
Miscellaneous : This is a group of volatile solvents or inhalants that provide euphoria,
emotional disinhibition and perpetual distortion of thought to the user. The main sources
are glues, spot removers, tube repair, perfumes, chemicals etc.
6.
Tranquilizers: They are believed to produce calmness without bringing drowsiness, they
are chiefly derived from Librium, Valium etc.
Causes of Drug Abuse
Haladu (2003) gave the following as the main causes’
i.Experimental Curiosity: Curiosity to experiment the unknown facts about drugs thus
motivates adolescents into drug use. The first experience in drug abuse produces a state of
arousal such as happiness and pleasure which in turn motivate them to continue.
ii.Peer Group Influence: Peer pressure plays a major role in influencing many adolescents
into drug abuse. This is because peer pressure is a fact of teenage and youth life. As they try
to depend less on parents, they show more dependency on their friends. In Nigeria, as
other parts of the world, one may not enjoy the company of others unless he conforms to
their norms.
iii.Lack of parental supervision: Many parents have no time to supervise their sons and
daughters. Some parents have little or no interaction with family members, while others
put pressure on their children to pass exams or perform better in their studies. These
phenomena initialize and increases drug abuse.
iv.Personality Problems due to socio-Economic Conditions: Adolescents with personality
problems arising from social conditions have been found to abuse drugs. The social and
economic status of most Nigerians is below average. Poverty is widespread, broken homes
and unemployment is on the increase, therefore our youths roam the streets looking for
employment or resort to begging. These situations have been aggravated by lack of skills,
opportunities for training and re-training and lack of committed action to promote job creation
by private and community entrepreneurs. Frustration arising from these problems
lead to recourse in drug abuse for temporarily removing the tension and problems arising
from it.
v. The Need for Energy to Work for Long Hours: The increasing economic deterioration that
leads to poverty and disempowerment of the people has driven many parents to send their
children out in search of a means of earning something for contribution to family income.
These children engage in hawking, bus conducting, head loading, scavenging, serving in
food canteens etc and are prone to drug taking so as to gain more energy to work for long
hours.
vi. Availability of the Drugs: In many countries, drugs have dropped in prices as supplies
have increased.
vii. The Need to prevent the Occurrence of Withdrawal symptoms: If a drug is stopped, the
user experiences what is termed “withdrawal symptoms”. Pain, anxiety, excessive sweating
and shaking characterize such symptoms. The inability of the drug user to tolerate the
symptoms motivates him to continue (Ige, 2000)
The Effects of Drug Abuse
Mba (2008) identified numerous negative effects of drug abuse on the body chemistry as
follows:
1.
Alcohol-related problems includes:
a. Physical problems e.g liver cirrhosis, pancreatic, peptic ulcer, tuberculosis,
hypertension, neurological disorder.
b. Mental retardation for the fetus in the womb, growth, deficiency, delayed motor
development.
c. Craniofacial abnormalities, limbs abnormalities and cardiac deficits.
d. Psychiatric e.g pathological drunkenness, suicidal behaviour
e. Socially-broken homes, increased crime rate, sexual offences, homicide and sexually
transmitted diseases.
2. Tobacco: Causes stimulation of heart and narrowing of blood vessels, producing
hypertension, headache, loss of appetite, nausea and delayed growth of the fetus. It also
aggravates or causes sinusitis, bronchitis, cancer, strokes, and heart attack.
3. Stimulants: Lethargy, irritability, exaggerated self confidence, damage nose linings,
sleeplessness, and psychiatric complications.
4.Inhalants: Causes anemia, damage kidney and stomach bleeding.
5. Narcotics: Causes poor perception, constipation, cough, suppression, vomiting, drowsiness
and sleep, unconsciousness and death.
Incidence of Drug Abuse among Nigerian Adolescents
Students, especially those in secondary school tend to see the drug user as one who is
tough, bold and strong. Many youngsters have been known to use drugs at the instance of peers,
elders or siblings. Students who usually feel inadequate have been known to use drugs to achieve
social acceptance. Esen (1979) stated that Nigerian secondary school adolescents under the
influence of Indian hemp shed all inhibitions and produce behaviour that is inconsistent with
school discipline. He went further to observe that the increasing incidence of drug abuse among
secondary school students is a contributory factor in the ugly confrontation between school
administration and students.
Odejide, (1979); Ogunremi and Rotimi, (1979); Agunlana, (1999); Ubom, (2004); Obiamaka,
(2004); Okorodudu and Okorodudu, (2004) in their research work indicated that the problem of
drug abuse know no boundaries or social class. It impedes the development of any society as it is a
threat to life, health, dignity and prosperity of all individuals. Fayombo and Aremu (2000) in their
research on the effect of drug abuse on educational performance of some adolescent drug abusers
in Ibadan found that the misuse of marijuana had reached an epidemic level in the present Nigeria
society, and that drug abuse could lead to reduce academic achievement or even halt one’s entire
academic process. Adesina, (1975); Ekpo, (1981); and Orubu, (1983) in their studies dwelled
extensively on reasons students use drugs include success in examination, social acceptance and
initiation of peers. Olatunde (1979) states that Nigerian adolescents take drugs such as
amphetamines and pro-plus as aid for success in examination. He postulated that those who take
drugs as aid for studies toward examinations are those with poor academic records, a history of
instability and family/social problems, while others, he commended; use rugs to increase their self
confidence, heighten pleasure, cope with feelings of depression and inadequacy, and to facilitate
communication.
Idowu (1987) found that students smoke and use drugs at the instance of friends/peers,
parents and television/radio advertisements. Oladele, (1989); Okorodudu and Okorodudu (2004);
and Enakpoya (2009) in their studies showed that adolescents were very susceptible to the influence
of their peers.
Strategies for Counselling
The following counselling strategies are suggested to help reduce drug abuse among
adolescents.
Establishment of Family Education on Drugs: The family is the nucleus of the social
organization. Parents should give their children appropriate education on drug use. They should be
encouraged by health authorities to offer family education on drug abuse to their children. They
should inform them of the dangers of drug abuse and dependence on their health, society and the
nation.
Establishment of Counseling Centres for Drug Control: Counselling centers should be
established in every community by the government or private individuals. Qualified health
counsellor should be employed in helping drug addicts or those dependent on drugs by giving
them special advice on how to go about the withdrawal system.
Designing Curricula on Drug Education: Ministry of education (State and Federal) should
as matters of urgency add to the curricula- drug education at all levels of education.
Campaign against Drug Abuse: National Drug Law Enforcement Agency (NDLEA) should
intensify their campaigns on antidrug in order to have a drug free society. The campaign against
use of certain drugs and misuse of drugs should be more intensified at the secondary school level
because it is the peak of adolescent. Also, government and other relevant authorities should lunch
out campaigns against drug abuse as well as dependence.
Effective study Habit for Students: An effective study is that which centers on a well planned
scheme of study involving sufficient recreational activities, enough resting time and sleep. Thus,
such well planned time table of study habits that make adequate provision for rest will enhance
good study habit without necessary resorting to the use of drugs to keep students artificially awake.
Establishment of Drug Awareness Units: Drug awareness units to be set up in all states and
moderated by the federal state and local governments. It should not be a panel established to try
people who use drugs as criminals, but to help solve their socio-psychological problem.
Parents and adults should refrain from using drugs indiscriminately in the presence of
youngsters and they should discourage their wards/children from associating with “unknown”
gangs or suspicious neighborhood peer groups.
Conclusion
Drug abuse is a problem that is causing serious concern to both individuals and
government all over the world. The problem is prevalent among adolescents who in most cases are
ignorant about the dangers inherent in drug abuse. Many of them engaged in drug abuse out of
frustration, poverty, lack of parental supervision, peer influence and pleasure. However, with
effective counseling programme, the problems can be tackled.
