Timoschenko, the establishment of a systematic approach in interdisciplinary researches of the science of criminal law should be constantly the subject of both critical analysis and adjacent analysis (through the processes of their convergence, integration and harmonization) along with pharmaceutical law, criminalistics, criminology, forensic medicine, forensic pharmacy and forensic psychiatry.
