Abstract


Drug abuse is becoming a serious threat in our society. Within the last decade, the involvement of Nigerian youths in drug related offences is becoming worrisome. Studies conducted by the National Drug Law Enforcement Agency (NDLEA) revealed that youths of both sex and between the ages of 13-35 years constitute the high-risk group for drug abuse in our society. Secondary school pupils are not left out, as some of them now indulge in drug abuse. Hence this study is aimed at creating a geospatial database and mapping of these drug-abuse hotspots and agencies involved so as to reduce or curb the drug-abuse incidents within the State. GIS has been identified as a veritable tool in tracking, monitoring and evaluating the occurrence and rate of drug-abuse in various streets and towns in Anambra State. Coordinates of the respective drug-abuse hotspots were captured with the use of a Garmin 760CS handheld GPS, these coordinates where later inputted in a GIS, ArcGIS 10.5 software and was used to map these hideouts. Also, several analyses like network analysis, buffering, time-distance analysis, cluster analysis and kernel density analysis were done in order to monitor the hotspots and cold-spots so as to depict the rate of occurrence in different towns. The results of these analyses show that Onitsha, Awka, Agulu, Nkpor and Nnewi posses the greater rate of occurrence due to the influence of the pressures due business districts and institutions which tends to bring so many youths together and this tends to increase the rate of illicit drug-abuse. The distance-time response analysis was done to identify the distance and time of response from several law enforcement agencies to the respective drug-abuse hideouts. Absence of a yearly occurrence record was serious trait through the period of the research work. It is recommended that pattern analysis, site suitability and positioning analysis should be done in future researches in order to track the rate of prevalence and as well map new prescribed sites for these law enforcement agencies outpost.
