The prevalence of substance abuse among university students, without due consideration to legal, normative, and medical guidelines for their lives, and the lives of others is worrisome, as it foretells potentially disastrous consequences for the users, the family, the communities, and the larger society. This paper interrogates students on the common abuse substances in the selected universities in Kwara State, Nigeria. The theoretical framework used was the socio-ecological theory. The study employed a mixed method in recruiting respondents to gather comprehensive insights. The findings showed that one of the social drugs known as alcohol ranked on the ladder of commonly abused substances, followed by marijuana and lysergic acid diethylamide (LSD). What contributed to these common abuse substances is the result of their availability and affordability. Addressing this social problem lies in strong family support and a positive socialization process, healthy peer relationships substance, reduction in substance availability, providing a conducive learning environment and gathering social support from the government and non-governmental organizations.
