The study results can add to the understanding of SUD outreach and low threshold work during pregnancy. The elements described in this study need further theoretical development, research and critical assessment. Building relationships during pregnancy were characterized by connecting within everyday life situations and supporting the development of an attachment relationship between the baby and the parents. To promote recovery, a comprehensive approach in which substance-related issues and mental health conditions are interconnected can be favored. Engaging early on during pregnancy might enhance success during future rehabilitation.
