The Addiction Severity Index has been formally adopted by which organization?

The Addiction Severity Index (ASI) is a widely used clinical tool to assess the severity of addiction and its impact on various aspects of a person's life. The correct answer reflects that the National Institute on Drug Abuse (NIDA) has formally adopted the ASI, acknowledging its importance in evaluating addiction's multifaceted nature and guiding treatment strategies. NIDA’s endorsement highlights the index's relevance in scientific research and clinical practice, validating its use in identifying treatment needs and measuring outcomes across different populations.

While the other organizations mentioned may have interest or involvement in drug use research or treatment, NIDA's formal adoption signifies its role in advancing addiction science and treatment methodologies based on evidence and comprehensive assessments provided by tools like the ASI. This distinction is crucial in understanding the landscape of addiction treatment and research.
