Drug cases have their own characteristics. This is because there are no victims and the approach of the investigative agency itself is very different from general criminal cases due to the closed nature. It is for this reason that each regional office independently operates a separate drug investigation unit. In order to approach the narcotics case, it is necessary to understand the unique investigation methods such as so-called 'official', and background knowledge about narcotics is a prerequisite. In addition, good results can be obtained only when the characteristics of various drug tests and related evidence are supported by jurisprudence and practical experience in narcotics cases.
