The purpose of this AMCHP-National Association of State and Alcohol Drug Abuse Directors (NASADAD) project is to highlight common harm reduction strategies used by state Maternal and Child Health (MCH) Title V programs and alcohol and drug abuse agencies to address the needs of pregnant and parenting women (PPW) who use substances. The goal of this project is to disseminate those strategies as a resource to states who wish to adapt them to their specific contexts.
