As early as 1998, the DILG has encouraged LGUs to organize their respective ADACs. These multi-sectoral councils are responsible for the formulation of plans, and the implementation of local anti-drug abuse programs, projects, and activities. A series of related policies reiterating the organization of local ADACs, and enumerating their specific roles and responsibilities have likewise been issued, one of which is Joint Memorandum Circular (JMC) No. 2018-01 between the DILG and the Dangerous Drugs Board (DDB) which provides for the implementing guidelines on the functionality, and effectiveness of local ADACs.

Republic Act No. 9165, otherwise known as the Comprehensive Dangerous Drugs Act of 2002, embodies the National Government's commitment to eradicate the country’s illegal drug problem. Article VII of the same law highlighted the vital participation of Local Government Units (LGUs) in safeguarding the citizenry from the harmful effects of dangerous drugs by giving priority to preventive or educational programs, and the rehabilitation or treatment of drug dependents.

Chapter 13.1 of the Philippine Development Plan (PDP) 2023-2028 states that, for the government's efforts to be people-centered, holistic, and human rights rights-based, and security, it shall promote a holistic approach to counter the proliferation of illegal and dangerous drugs to ensure peace and security. It further stresses the importance of a whole-of-nation approach in addressing the problem of illegal drugs thereby, placing the LGUs and the Department of the Interior and Local Government (DILG) to be at the forefront of the anti-illegal drug program.

Local Anti-Drug Abuse Councils (ADACs) have a critical role in the coordination and proper monitoring of drug-related incidents. This entails cohesion of policies for the inter-local government roles which can provide an enabling environment for functional and effective ADACs. 

To ensure the continuous improvement in the performance of ADACs in the implementation, monitoring and evaluation of anti-illegal drug activities, the DILG, through the Philippine Anti-lllegal Drugs Strategy - Project Management Office (PADS-PMO), shall conduct a Performance Audit covering Provincial, City, and Municipal ADACs. 

This Anti-Drug Abuse Council (ADAC) Performance Audit is a collaborative effort between national government agencies (NGAs), local government units (LGUs), and civil society organizations (CSOs). It employs a multi-level and participatory audit structure to ensure the integrity of the audit process and its results. This Performance Audit aims to (1) Assess the functionality and effectiveness of local ADACs based on existing issuances and policies; (2) Determine ADAC-initiated and / or endorsed innovations and best practices at all levels; (3) Create a platform for evaluation and assessment; and (4) Recognize the best, effective, and performing ADACs.
