Concept of drug/Substance Abuse
The term “drug/substance abuse†refers to the use of a drug/substance with such frequency that it causes physical or mental harm to the user or impairs social functioning. Although the term seems to imply that drug/substance users misuse the drug/substances they use, in fact, it is themselves or others they abuse by using drug/substances (Lexicon Universal Encyclopedia 1989:276).
Traditionally, the term drug/substance abuse refers to the use of any drug/substance prohibited by law, regardless of whether it was actually harmful or not. This means that any use of a banned substance such as marijuana for example, even if it occurred only once in a while, could constitute abuse, while the same level of alcohol consumption would not. In view of the ambiguity of the term „abuse‟, the United States National Commission on drug/substance abuse stated in 1920 that “it has no functional ability and has become no more than a code word drug/substance presently considered wrong and illegal (Lexicon Universal Encyclopedia 1989).
The drug/substances commonly abused include:- cannabis, sativa (marijuana or Indian hemp), cocaine, heroine, morphine, opium, tobacco and alcohol. The sale and consumption of these drug/substances has caused a lot of problems in Nigeria society and in international communities. This is the reason why most of the drug/substances are prohibited by law and there are national and international agencies established for the purpose of monitoring and controlling illegal drug/substance trade. In 1980, for instance, the Federal Government established National Drug/substance Law Enforcement Agency (NDLEA) to fight drug/substance abuse and trafficking in the country. Since then, it has arrested many people involved in illicit drug/substance activities and has seized various quantities of hard drug/substances. The then National Chairman of of NDLEA, stated in 2003 that the agency had seized more than 40million tons of cannabis, cocaine and heroine in that last one year. He also stated that a reasonable number of drug/substance barons and traffickers were also arrested during the period and some of them had been successfully prosecuted and jailed.
Common drug/substances abused by youths in Ilorin metropolis
According to World Health Organization (WHO 2002) the drug/substances commonly abused include cannabis sativa, (marijuana or Indian hemp), cocaine, heroine, morphine, opium, tobacco, alcohol etc. The sale and consumption of these drug/substances has caused a lot of problems in the Nigerian society and in international community. Alcohol belongs to the category of psychoactive drug/substances that depress and at the same time stimulate the functions of the central nervous system (WHO, 2002). The issue of alcohol use and abuse among youths in Ilorin metropolis of Kwara state and its neighbourhood has been a great concern to all and sundry. The abuse of alcohol seems to make it addictive and the partakers are referred to as all who lies. It involves alcohol to an extent which exceeds the norms of the society and which adversely affects the drinker’s health, relationship with others and economic functioning. In other words, the victim finds himself drinking when he intends not to drink or drinking more than planned. It is the claim of W.H.O that, alcohol though legal in many countries can be an even bigger threat like cannabis, cocaine and heroine. It is probably the most viccous drug/substance of all (Shearer 1980).
The cannabinal drug/substance firmly has been well known since ancient times. The drug/substances are produced from many varieties of cannabis sativa. The leaves and the flowering tops of the female plant secret an amber – colour resin containing the chemical cannabine, cannabinol, tetrahydro cannibinol which is believed to be the active substance causing the mood modification and behavior changes in the user (Jones 1999).
