Abstract
This study examines the impact of cannabis use on the academic performance of students at Kitoko Institute, located in the Kwenge sector, Kwilu Province, Democratic Republic of the Congo. Using a cross-sectional, descriptive, and analytical approach, the research involved a purposive sample of 41 students surveyed through a structured questionnaire. The collected data reveal that 61% of the participants had already used cannabis, mostly between the ages of 14 and 16. Cannabis use was associated with a significant decline in academic performance, characterized by increased absenteeism, reduced concentration in class, and low academic achievement. Peer influence and lack of parental support emerged as major contributing factors. The study highlights the need for a multisectoral response involving families, schools, and public health stakeholders to prevent risky behaviors in a socioeconomically vulnerable context. It recommends the implementation of targeted awareness programs and enhanced parental support to promote a school environment conducive to adolescent success.
