This refers to a comprehensive, medically managed treatment program that provides intensive, 24-hour care within a hospital or specialised facility. This level of treatment requires at least one overnight stay and is designed for individuals who need continuous medical supervision, structured therapeutic support, and stabilisation. Inpatient treatment addresses both physical and psychological aspects of substance use or mental health conditions. It often serves as the first step before transitioning to less intensive levels of care, such as residential or outpatient programs.
