Abstract: The results of forensic pharmaceutical monitoring show that criminal cases are most often initiated under Art. 305-322 of the Criminal Code of Ukraine. At the same time, investigators appoint forensic narcological examination, forensic medical examination. In addition, we have recorded that in recent years, the pre-trial investigation has also appointed phonoscopic and computer examinations. Phonoscopic examination may be intended to investigate conversations between persons by telephone about the facts of illicit trafficking in psychoactive substances, which were intercepted by operational and investigative bodies with the special permission of the court. If the suspect's activities are related to certain public or private structures, which is reflected in the computer technology that records the various connections of the operation of institutions, then a computer examination may be ordered.
