Maternal substance use disorders are considered a significant public health issue in Australia and globally. While it does not necessarily lead to inadequate parenting, it is strongly linked to poorer health and social outcomes for their infants. Women with substance use disorders have unique experiences compared to men, including complex histories, mental health disorders and trauma from intimate partner violence. Additionally, it is estimated that many of these women have children, and approximately 60-70% of Australian children were removed from households where substance abuse was present. Women who inject drugs face multiple challenges and are some of the most vulnerable women in society.
