Introduction

The aim of this article is to review and synthesise existing knowledge on the experiences of siblings of those with substance-use disorders, with particular attention to family roles, psychosocial consequences and the dynamics of relationships with an addicted sibling. It also identifies recurring patterns in the literature like over-responsibility, emotional invisibility, expe­riences of loss and relational ambivalence.

Literature review

The analysis shows that siblings of those with substance use disorders often take on highly responsible, caregiving or quasi-parental roles, which can lead to the internalisation of beliefs about the secondary importance of their own needs and result in emotional burden. These relationships are marked by ambivalence, where loyalty and concern coexist with anger, frustration and a need for distance. Siblings frequently experience social stigma, feelings of invisibility within both family and institutional contexts, and practical as well as material burdens linked to a loved one’s dependence. Growing up in such an environment may also shape attitudes toward psychoactive substances, ranging from avoidance to an increased risk of developing substance-related problems themselves.

Conclusions

The experiences of siblings of people with substance-use disorders remain relatively underrepresented in both research and support systems, suggesting insufficient recognition of their specific needs. The literature highlights the need for further research to better understand their situation and for the development of more adequate support and intervention strategies that take into account the unique nature of sibling relationships in families affected by dependence.
