Maternal Substance Use, Child Maltreatment Risk, and Child Welfare Policy: An Equality-Based, Child-Centered Framework

Substance use within caregiving environments is associated with increased risk of child maltreatment and adverse developmental outcomes. Child welfare systems often emphasize family preservation and reunification; however, in certain contexts, these goals can conflict with the need to prioritize child safety when risk factors are not adequately addressed. This narrative review and policy analysis examines the intersection of maternal substance use, child maltreatment, and reunification practices through an equality-based, gender-neutral accountability framework, synthesizing evidence from a range of clinical, epidemiological, and child welfare studies. A structured narrative review and policy analysis were conducted using PubMed, JAMA, the American Psychological Association, and Google Scholar, along with governmental and epidemiological reports. Literature addressing caregiver substance use, child maltreatment, trauma exposure, foster care, reunification, and long-term developmental outcomes was screened using predefined inclusion and exclusion criteria and synthesized narratively by thematic category. Exposure to caregiver substance use and associated forms of maltreatment (verbal, emotional, psychological, physical, and abandonment) is strongly and consistently associated with increased risk of long-term mental health disorders, behavioral dysregulation, and chronic health conditions. Reunification without sustained behavioral change and verified safety is often associated with higher levels of re-traumatization in children. Child welfare policies may benefit from emphasizing gender-neutral, sustained behavioral change prior to reunification and from prioritizing child-reported safety and long-term stability in reunification decisions over permanent re-homing.
