When a family member is experiencing a mental or substance use disorder, it can affect more than just the person in need of recovery. Evidence has shown that some people have a genetic predisposition for developing mental and substance use disorders, and may be at greater risk based on environmental factors such as having grown up in a home affected by a family member’s mental health or history of substance use. Families should be open to the options of support groups or family therapy and counseling, which can improve treatment effectiveness by supporting the whole family.
