Educating young people about drugs: a systematic review

Area of Science:

• Public Health
• Substance Abuse Prevention
• Youth Intervention

Background:

• Young people (8-25 years) are a key demographic for substance use interventions.
• Interventions aim to prevent illicit substance use or reduce harm from ongoing use.
• Evaluations span various settings: schools, community, family, therapeutic, and mass media.

Purpose of the Study:

• To systematically review and assess the effectiveness of interventions for preventing or reducing illicit substance use in young people.
• To evaluate interventions aimed at reducing harm associated with continued substance use.
• To identify methodologically sound studies for meta-analysis.

Main Methods:

• Systematic review of electronic and hand-searched reports.
• Inclusion criteria: evaluations of illicit drug use interventions with sufficient methodological detail.
• Meta-analyses conducted on methodologically sound studies.

Main Results:

• Most studies evaluated school-based interventions targeting alcohol, tobacco, and marijuana.
• Interventions showed small impacts that diminished over time.
• Evaluations of interventions for hard-to-reach groups were inadequate.

Conclusions:

• Improved evaluative methods are needed for interventions targeting specific youth populations.
• Insufficient evidence exists to assess the effectiveness of current drug education approaches.
• Future interventions require better targeting to meet the specific needs of recipients.
