In the late stage of dependence disease, the user will be severely impaired in all areas of function. Which of the following is the BEST treatment plan for a person in the late stage of this disease?

A. Multi-disciplinary biological, psychological and social treatment plans Effective treatment for late-stage addiction requires a comprehensive, integrated approach including detox, therapy, medical support, and social rehabilitation. B. Self-directed treatment including complete abstinence This may work for mild cases, but late-stage dependence typically requires professional intervention. Self-treatment is usually insufficient. C. Punitive (punishment) to stop use of the addictive substance Punishment alone does not address the underlying causes of addiction and often worsens stigma and resistance to care. D. Treatment with medications and family support These are important components but not enough on their own. A full plan must include psychological and social rehabilitation.
