For national policy, the government of Thailand has placed substance abuse on the national agenda since the last decade up to present. However, there were some problems in operation of the government policy into real practice resulting from having less concern and use of epidemiological situation into effective prevention and control actions on the part of responsible sectors and staff(4). This coupled with limited utilization of public health surveillance system of substance abuse in the area had made problems related to substance abuse in uncontrolled situation )(2,4). Importance of public health surveillance and action in effective public health practice has been well recognized to reduce national and international threats of public health problems. The World Health Organization has emphasized the needs to facilitate and standardize surveillance and action assessments and to include integrative strategies in the reform process targeting on both national and local level since 2002(6). Surveillance in public health was defined as the ongoing systematic collection, analysis, and interpretation of outcome-specific data for use in the planning, implementation, and evaluation of public health practice(9,10). The substance abuse surveillance system in Thailand has been established since 2004. It comprised both national (for example the Office of the Narcotic Control Board), and local organizations (for example, the Provincial Substance Abuse Fighting Center and the District Substance Abuse Fighting Center)(2,4).
