In January 2019, Nigeria released its first national drug use report, which disclosed that nearly 15 million people in the country are drug users. This publication presented a window of opportunity for geographic insights into the emerging illicit drug use (IDU) epidemic in Nigeria. Using a mixed theory approach, we conducted an in-depth spatial analysis of the IDU epidemic with a view to determining the degree of clustering and identifying factors that can explain its geographic pattern in Nigeria. We detected geographic clustering and hot spots in Oyo State, southwest Nigeria. The multivariate spatial analysis found that state gross domestic product per capita and unemployment explain 15 to 37 percent of IDU among the thirty-six states and the Federal Capital Territory. Based on theoretical and empirical evidence of the study, the country’s drug policy needs to give due recognition to prevention and treatment as effective means of IDU control.

2019年1月，尼日利亚发布首份全国吸毒报告，披露该国近1500万人吸毒。该出版物为深入了解尼日利亚新出现的非法药物使用 (IDU) 流行病提供了机会之窗。我们使用混合理论方法对 IDU 流行进行了深入的空间分析，以确定聚集程度并确定可以解释其在尼日利亚的地理模式的因素。我们在尼日利亚西南部的奥约州检测到地理集群和热点。多元空间分析发现，在 36 个州和联邦首都直辖区，各州的人均国内生产总值和失业率占 IDU 的 15% 至 37%。根据研究的理论和经验证据，
