The study adopted a quantitative research method and gathered data through the adaptation of standardized scales of measurements on peer pressure and substance abuse. Data was collected from 322 out-of-school adolescents from selected bus terminals in Ibadan, Oyo state. Descriptive statistics and inferential (Pearson r and ANOVA) were used in the study. From the findings, the prevalence of substance abuse among out-of-school adolescents can be found to be 39.1%. Also, a significant and positive relationship was found between substance abuse and peer pressure (r = 0.60; p < 0.01). Further, adolescents who indicated that their parents are active drug users reported the highest substance abuse (Mean = 19.181; SD = 4.010). In addition, adolescents who noted that their parents have a history of drug use reported the highest on substance abuse (Mean = 19.621; SD = 4.213). Adolescents who indicated that they are very close to drug purchase reported significantly higher substance abuse (Mean = 20.161; SD = 4.177). It was concluded from the study that peer pressure, parental use and proximity to drug sales were significant determinants of substance abuse among out-of-school adolescents. Concerned agencies were advised to offer policies that encourage more adolescents to enrol in formal education to prevent further increase of out-of-school adolescents in containing substance abuse menace. %K Substance Abuse %K Adolescents %K Peer Pressure %K Parent %K Proximity to Drug %U http://www.oalib.com/paper/6859447
