The unit of treatment in family therapy is generally the family, or the person within the framework of the family system. Thus the individual abusing substances can be taken as a subsystem in the family, the individual whose indicators have serious repercussions for the whole family. Generally, the familial affiliations in this subsystem are the concerns for therapeutic intervention as well as interest (Morgan & Lizke, 2013). The role of the therapist is mostly to facilitate problem-solving meetings as well as discussions, frequently with whole family groups or sometimes subsets thereof. However, at times it can also be done with a sole member who could or could not be the person having substance abuse disorder (Morgan & Lizke, 2013).
