How does substance use impact psychosocial wellbeing?

• A. It can worsen mood and anxiety disorders and frequently co-occurs with depression, anxiety, and trauma.
• B. It improves mood and enhances functioning for most individuals.
• C. It has no effect on relationships or functioning.
• D. It only affects physical health, not psychosocial wellbeing.

Answer: (A)

Substance use often disrupts psychosocial wellbeing by worsening mood and anxiety symptoms and by commonly co-occurring with depression, anxiety, and trauma. This creates a cycle: distress can lead to using substances as a coping mechanism, while continued use worsens sleep, stress regulation, and overall functioning. Beyond mood, substance use strains relationships, reduces participation in work or school, and impairs daily functioning—all key aspects of psychosocial wellbeing. This makes the statement the best choice because it reflects both psychiatric comorbidity and broader social and functional impairment, rather than suggesting mood improvement, no effect, or impact limited to physical health.
