The Effectiveness of Universal Educational Interventions for Prevention of Illicit Drug Use among University Students: A Systematic Review

The extent of illicit drug use among university students necessitates effective preventive programs. To identify and assess the effectiveness of university-based interventions in preventing or reducing illicit drug use.

The MEDLINE (PubMed), SCOPUS, ISI (Web of Science), and other sources were searched according to the Cochrane Collaboration method. RCTs, CRTs and non- RCTs evaluating university-based interventions designed to prevent illicit drug use were reviewed. Data were extracted independently by two reviewers. The quality of the publications was assessed. Interventions were classified by type, provider, duration, and theoretical background.

Of 6652 papers, 11 studies met the eligibility criteria that were conducted between 1987 and 2020. The effectiveness of interventions was different. Substantial heterogeneity among the studies prevented the integration of results for estimating summaries.

Despite the importance of the subject, there is a paucity of studies about specific educational programs for illicit drug use, indicating the necessity of further research in other countries.
