Aim: To estimate the prevalence of drug and polydrug use among drunk-drivers during the driving license regranting program, in order to assess the inclusion of toxicological tests on hair and urine samples in the systematic methodology in this category of subjects. Short summary: A total of 2160 drunk-drivers were tested for alcohol and drugs during driving license regranting. Thirty-one subjects showed alcohol use, 212 illicit drug use and, among these, 131 were polydrug users. Nineteen different patterns of drug and polydrug use were found. Cocaine was detected in 165 subjects. Methods: The study was performed on 2160 drunk-drivers examined at Legal Medicine and Toxicology Unit of the University of Padova, in a 3-year-period (20142017). The positivity for one or more illicit drugs in hair or urine samples was confirmed by LC/MS and GC/MS methods. Chisquare test, Fischers exact test and CochranArmitage Trend test were used to study the correlation between general characteristics of the examined sample and the presence of drug/polydrug use. Results: Thirty-one subjects showed alcohol use, 212 illicit drug use and, among these, 131 were polydrug users. Nineteen different patterns of drug and polydrug use were found. Cocaine was detected in 165 subjects in whom 122 showed a concurrent use of alcohol and cocaine, identified through the detection of cocaethylene in hair samples. No significant association and/or trends between drug/polydrug use and the general characteristics of the sample were detected. Conclusions: The results show that drug and polydrug use among drunk-drivers should be subjected to toxicological as well as alcohological monitoring, especially in the regranting procedure. The implementation of this procedure could improve the knowledge of dimensions of the issue, providing a powerful means for the reduction of phenomenon of driving under the influence of alcohol and drugs.

Abstract

Aim: To estimate the prevalence of drug and polydrug use among drunk-drivers during the driving license regranting program, in order to assess the inclusion of toxicological tests on hair and urine samples in the systematic methodology in this category of subjects. Short summary: A total of 2160 drunk-drivers were tested for alcohol and drugs during driving license regranting. Thirty-one subjects showed alcohol use, 212 illicit drug use and, among these, 131 were polydrug users. Nineteen different patterns of drug and polydrug use were found. Cocaine was detected in 165 subjects. Methods: The study was performed on 2160 drunk-drivers examined at Legal Medicine and Toxicology Unit of the University of Padova, in a 3-year-period (20142017). The positivity for one or more illicit drugs in hair or urine samples was confirmed by LC/MS and GC/MS methods. Chisquare test, Fischers exact test and CochranArmitage Trend test were used to study the correlation between general characteristics of the examined sample and the presence of drug/polydrug use. Results: Thirty-one subjects showed alcohol use, 212 illicit drug use and, among these, 131 were polydrug users. Nineteen different patterns of drug and polydrug use were found. Cocaine was detected in 165 subjects in whom 122 showed a concurrent use of alcohol and cocaine, identified through the detection of cocaethylene in hair samples. No significant association and/or trends between drug/polydrug use and the general characteristics of the sample were detected. Conclusions: The results show that drug and polydrug use among drunk-drivers should be subjected to toxicological as well as alcohological monitoring, especially in the regranting procedure. The implementation of this procedure could improve the knowledge of dimensions of the issue, providing a powerful means for the reduction of phenomenon of driving under the influence of alcohol and drugs.
