arcotic drugs have a medical use, although the incidence of driving under the influence of drugs, which are often abused, has increased in recent years. Various studies have been conducted on this subject, which has increasingly been put on the agenda of countries. The substances Driving Under the Influence of Drugs A AB BS S T TR RA AC CT T O Ob bj je ec ct ti iv ve e: : Driving performance can easily be deteriorated as a result of drug use. Many observational studies show an increase in the presence of drugs detected in biological samples among drivers. This is an alarming situation, and the likelihood of drug users being exposed to a fatal accident,-especially after multiple drug use-is higher than that of non-users. M Ma at te er ri ia al l a an nd d M Me et th ho od ds s: : In our study, cases with requested reports regarding "the effect of drug on safe driving" between 2012 and June 2018, from the 5 th Specialized Board of The Council of Forensic Medicine were examined in means of distribution by year, sender judicial authorities, regional distribution, biological samples used during evaluation, the types of drugs and their frequency of detection, the rates of verification analysis performed and the report results of the board. R Re es su ul lt ts s: : It has been determined that cases regarding driving under the influence of narcotic drugs have increased over years. The identified drugs in order of frequency are cannabis, amphetamine, methylenedioxymethamphetamine (MDMA), synthetic cannabinoids, benzodiazepines and opioids. Multiple drug use was detected in 38 out of 88 cases. In 56% of the cases, it was evaluated that the person could not handle and manage the vehicle safely. In 29% of the cases positive for screening test, there was no opinion presented since confirmation analysis in blood was not performed. C Co on nc cl lu us si io on n: : The number of drug users has been increasing over years, and risk assessment and prevention of drug-related vehicle use are becoming increasingly important.

Birçok gözlemsel çalışma, sürücüler arasında biyolojik örneklerde tespit edilen uyuşturucu varlığının artmakta olduğunu göstermektedir. Bu endişe verici bir durum olup uyuşturucu kullanan sürücülerin ölümcül bir kazaya maruz kalma olasılığı, özellikle çoklu uyuşturucu kullanımından sonra, kullanıcı olmayanlardan daha yüksektir.
