Abstract
We established a database system for amphetamine-type stimulants (ATS) tablets operated on Microsoft Access software. The database has 34 fields composed of information on pictures, shapes, colors, logo marks, weight, diameter, thickness, contents, etc. The ATS tablet information registered in each prefectural police headquarters are accumulated in the host database of the National Police Agency (NPA) via an intra-net network. The update data, being confirmed by the NPA, is supplied via intra-net or compact disk-read only media (CD-ROM). This information would lead to rapid identification of ATS tablets in forensic laboratories. In addition, accumulation of data would be useful not only for the investigation relating to seizures but also for identification of trafficking routes and sources of supply.
