Module 1: Introduction to Substance Abuse Prevention

Substance use prevention is sometimes reduced to a simple message: teach people that drugs are dangerous and expect them to make better choices. This approach assumes that behavior develops mainly from personal knowledge, attitudes, or willpower. Individual choices matter, but choices do not occur in isolation. People develop within families, peer groups, cultures, schools, workplaces, communities, institutions, and systems of law and policy. Each environment can increase risk, provide protection, or create competing expectations.

This chapter introduces the major principles and levels of substance use prevention and then applies the Ecological Identity Model (EIM) to them. EIM provides a way to examine how belonging, identity, relationships, culture, institutions, and perceived consequences shape behavior. The goal is not to remove personal responsibility. It is to understand the conditions under which choices become more or less possible, supported, and sustainable.

After completing this Module, you should be able to:

• Distinguish prevention, treatment, recovery, and harm reduction.
• Differentiate universal, selective, and indicated prevention.
• Compare primary, secondary, and tertiary prevention without treating the categories as interchangeable.
• Explain how risk and protective factors operate across ecological contexts and over time.
• Describe the importance of developmental timing and cumulative risk.
• Compare individual and ecological explanations of substance use.
• Define the EIM concepts of ecological systems, belonging, identity resonance, relational security, cross-pressure, and perceived ecological cost.
• Apply EIM to identify prevention strategies at individual, relational, cultural, institutional, community, and policy levels
