This meta-analysis evaluated the long-term impact of these programmes across different settings, focusing on student behaviour and substance use rates. Utilising a systematic review approach with databases such as PubMed, PsycINFO, and Scopus, studies meeting specific criteria were included. The analysis revealed a statistically significant reduction in substance abuse rates by $5\%$ (95% CI: [3%, 7%]) among students exposed to these programmes compared to control groups. These findings suggest that school-based mental health care initiatives are effective in preventing substance use
