Parental substance abuse can negatively impact children in several ways. Approximately 9.5 million children in the US live with at least one parent who abuses alcohol or illicit drugs. Children of substance-abusing parents are more likely to experience abuse or neglect, and are also more likely to develop substance abuse problems themselves. They may exhibit behaviors like low self-esteem, aggression, or difficulty concentrating due to issues like lack of attachment or feeling shame. Resources for these children include counseling, support groups, child protective services, or living with other family members.
