The document discusses the negative impacts of parental substance abuse on children. It notes that children of substance abusers are more likely to experience abuse and neglect, develop substance abuse issues themselves, and suffer from mental health problems. They often take on dysfunctional family roles like hero, scapegoat, or lost child to cope with the unstable home environment caused by their parent's addiction. Overall, parental substance abuse disrupts children's development and places them at higher risk for both short- and long-term issues.
