Drug investigation

The main task of the Drug Investigation Department is the identification of illicit narcotic drugs, new psychoactive substances, and drug precursors in seizures in order to give information to the prosecution or intelligence purposes.

In accordance with the national law, the penalty depends on the quantity of pure drugs and new psychoactive substances, therefore the laboratory does quantification for controlled substances including traditional and new drugs.

The laboratory is accredited since 2013 according to ISO/IEC 17025 for identification of illicit drugs and quantification of main drugs.
