According to the Health Service Executive (2017), to sustain recovery in services, structural, organisational and cultural changes within services must occur. Critically discuss how these changes may be actualised within contemporary Irish mental health care

Services for the prevention and treatment of substance misuse and substance use disorders have traditionally been delivered separately from other mental health and general health care services. Because substance misuse has traditionally been seen as a social or criminal problem, prevention services were not typically considered a responsibility of health care systemsⁱ; and people needing care for substance use disorders have had access to only a limited range of treatment options that were generally not covered by insurance. Effective integration of prevention, treatment, and recovery services across health care systems is key to addressing substance misuse and its consequences and it represents the most promising way to improve access to and quality of treatment. Recent health care reform laws, as well as a wide range of other trends in the health care landscape, are facilitating greater integration to better serve individual and public health, reduce health disparities, and reduce costs to society.
