Chapter 30: Substance Use & Community Health

Substance Use & Community Health exploration of substance use within the framework of Canadian community health nursing provides a foundational understanding of the complexities surrounding recreational consumption, problematic patterns, and the clinical definitions of dependency and addiction. Central to the discussion is a praxis-oriented approach that prioritizes social justice and equity, encouraging healthcare providers to look "upstream" at the structural inequities and power imbalances that drive substance-related issues. The text traces the historical progression of Canadian drug policy, evolving from moralistic prohibition and the enforcement-heavy "war on drugs" toward the modern four-pillars strategy that balances prevention, treatment, enforcement, and pragmatic harm reduction. An intersectional lens is applied to illustrate how various social locations—such as race, poverty, gender identity, and historical trauma—intersect to create unique vulnerabilities and barriers to care. Community health nurses are equipped with tools for equity-oriented care, emphasizing the necessity of trauma- and violence-informed practices and cultural safety, particularly when managing sensitive cases like chronic pain or maternal health. The narrative further examines the multifaceted consequences of substance use, covering both legal burdens like tobacco-related illnesses and alcohol-induced conditions such as Fetal Alcohol Spectrum Disorder, as well as the risks of illicit substances like opioids and fentanyl. By detailing specific interventions across the five levels of prevention—ranging from primordial policy advocacy to quaternary efforts to eliminate systemic stigma—the chapter provides a roadmap for nurses to support individuals and communities through evidence-based, compassionate, and nonjudgmental care.
