In this study I take a closer look at siblings of drug addicts. We can find similar researches about parents and spouses, but rarely about siblings. The purpose of this study is to bridge this gap. In this research, five semi-structured interviews were conducted with members of the Blue Point Foundation Sibling Group, and one interview was done with a non-member. The interviews were processed with thematic analysis.

Results: The results show that substance use was negatively altering the relationships between siblings and family members. In all cases siblings were aware of substance use way before their parents. They feel responsible for saving the drug user family member. Substance use negatively affects school achievements, work performance and day-to-day life of those around the user.

Conclusion: I would like to raise the attention of professionals and parents for the need of helping siblings of drug users.
