Prevalence and factors associated with substance use among university students in South Africa: implications for prevention.

Results show the majority of sampled students had started using substances (both alcohol and other substances) only after entering university. The results call into question seminal findings relating to substance use and the university environment. The novel findings of this study could serve as a baseline input to inform policymakers, programme developers, service providers, parents, and other stakeholders who are involved in the design and implementation of more effective awareness, prevention and, needs-based intervention services.
