Unit
- Substance abuse: The recurrent use of alcohol, illicit drugs, or prescription medications in ways that cause significant impairment or distress. This includes compulsive use, tolerance, withdrawal, and continued use despite negative consequences. Understanding this definition is the first step in prevention, as it frames the problem as a health condition rather than a moral failing.
- Addiction: A chronic, relapsing brain disorder characterized by compulsive drug seeking and use despite harmful outcomes. Addiction changes brain structure and function, affecting reward, motivation, and memory circuits. Prevention strategies must account for these neurobiological underpinnings to be effective.
- Substance use disorder (SUD): The clinical diagnostic term from the DSM-5 that categorizes substance-related problems on a spectrum from mild to severe. SUD criteria include impaired control, social impairment, risky use, and pharmacological criteria. Prevention efforts target reducing the incidence and progression of SUD.
- Primary prevention: Aims to prevent substance use before it starts, targeting the general population or at-risk groups through education, policy, and environmental change. Examples include public awareness campaigns and school-based life skills training.
- Secondary prevention: Focuses on early identification and intervention for individuals who have begun using substances but are not yet dependent. This includes screening programs and brief counseling to halt progression.
- Tertiary prevention: Designed for individuals with established SUD to reduce harm and support recovery. It includes treatment and relapse prevention programs, aiming to improve quality of life and prevent further deterioration.
- Prevention science: The interdisciplinary field that studies risk and protective factors, evaluates intervention effectiveness, and translates research into practice. Prevention science provides the evidence base for all prevention activities.
- Public health approach: A framework that addresses substance abuse at the population level through surveillance, risk factor identification, intervention development, and implementation. It emphasizes systemic solutions over individual blame.
- Risk factors: Conditions or attributes that increase the likelihood of substance use initiation or progression to disorder. These can be individual (e.g., impulsivity, early use), relational (e.g., family conflict, peer pressure), or community-level (e.g., poverty, availability of substances). Prevention programs aim to reduce exposure to these factors.
- Protective factors: Characteristics that buffer against substance use, such as strong family bonds, positive school environment, and access to prosocial activities. Strengthening protective factors is a core prevention strategy, as they promote resilience and healthy development even in the presence of risk.
- Evidence based prevention: Interventions that have been rigorously tested and proven effective through scientific research. These programs follow standardized protocols and are often manualized to ensure fidelity. Examples include LifeSkills Training and the Good Behavior Game. Using evidence based programs maximizes impact and resource efficiency.
- Environmental prevention: Strategies that modify the physical, social, or economic environment to reduce substance abuse. This includes policies like raising alcohol taxes, reducing outlet density, enforcing minimum drinking age laws, and creating smoke-free spaces. Environmental approaches can reach entire populations and produce lasting change.

Quick Revision
- Substance abuse is a pattern of harmful substance use; addiction is a chronic brain disorder.
- Primary, secondary, and tertiary prevention target different stages of substance use.
- Prevention science and public health approaches guide effective strategies.
- Prevention specialists focus on education, collaboration, and evaluation, not clinical treatment.
