Against the backdrop of debates and contestations in the literature on the efficacy of interventions of Faith-based organisations (FBOs) with regard to vulnerable people, this study subjects the social reintegration programmes of three selected FBOs working with recovering drug-addicts in South-western Nigeria to a sociological scrutiny so as to understand the social character, effectiveness and local appropriateness of their programmes. Specifically, the study examined the key attributes of the social reintegration programmes offered by the selected FBOs as well as the level and extent of compliance of such programmes with the prescriptions and idealisations as enunciated in relevant global and national policies and institutional frameworks. The theoretical underpinning of this study was derived from assumptions of structural-functionalism of Durkheim and Expectancy disconfirmation theory. Adopting an exploratory approach, the study utilised a blend of survey, key informant interviews, in-depth interviews, observation and document review to gather data. Survey data were collected from a random sample of 156 inmates of the social reintegration facilities of three (3) FBOs in Oyo, Ogun and Lagos states in South-West Nigeria. Qualitative data were sourced through 15 in-depth interviews, 9 key informant interviews and scientific information generated from observation and document review. The quantitative data gathered were analysed using descriptive statistics, while the qualitative data were processed with the use of content analysis. Findings from the study indicate that the selected FBOs have only recorded little success in terms of addressing the social needs of the inmates. For one thing, FBOs’ detoxification programme for recovering drug-addicts tilted more towards human rights violation than serve as an exercise that aided recovery. One key finding was that there was a huge disconnect between global prescriptions on social reintegration services and what the selected FBOs offered to the inmates. The study concluded from its findings that any social reintegration programmes aimed at protecting recovering drug-addicts from further social exclusion and facilitate their social inclusion in South-West Nigeria must extend beyond mere spiritual provisioning to upholding their rights to human dignity and providing opportunities and tools that address their crucial social needs in terms of housing, education, vocation and employment.
