Aim: This study focused on the simultaneous detection of amphetamine, 3,4-methyl enedioxy methamphetamine, morphine, benzoylecgonine, and 11-nor-9-carboxy- tetrahydrocannabinol (Δ9-THC-COOH) in whole blood and DBS. It is aimed to select a solvent mixture for liquid-liquid extraction (LLE) technique employing LC-MS/MS. The obtained DBS results were compared with the whole blood samples results.

Methamphetamine as the most common concomitant substance used with pregabalin misuse.

Background And Aim: Non-medical use of Pregabalin (PGB) is a growing concern in many countries because of the serious consequences associated with their abuse. Judicial cases within the probation system, multiple drug users, and patients in treatment programs administered PGB at higher doses than suggested, commonly without prescription. For this reason, it is important to analyze PGB by adding it to the routine analysis scale in determining whether PGB is used for medical purposes or abuse.

The role of aggression in substance use: The prison case.

Objectives: Substance use and aggressive behaviour pattern is considered as a serious criminal behaviour threat. This analytical cross-sectional study was designed to determine the level of aggression of convicts with substance use and to determine the variables predicting the substance use characteristics of convicts.

Methods: The study was carried out with 255 male convicts in 2 different closed penal execution institutions in Izmir province.

Pregabalin Qualitative Detection in Turkish Forensic Cases Between 2017 to 2018.

Pregabalin (PGB) has been commonly subjected to diversion, from being a prescription drug to a recreational drug. In this study, pregabalin use (which is one of the substances subject to control in Turkey) and the concomitant use of other substances in cases admitted to the Izmir Forensic Medicine Institute was evaluated. Samples from 15,259 cases were screened, between June 2017 and December 2018, for the presence of PGB, and PGB positive cases were further analyzed.

Development of analytical method for illegal substances in sweat and comparison of the effectiveness of sweat collection materials.

Purpose: Sweat analysis can yield valuable information in forensic investigations, diagnosis and treatment. The purpose of this study was to develop a validated gas chromatography-mass spectrometric method for the detection of illegal substances in sweat after optimizing the method by chemometric approach. This study also investigated the effectiveness of alternative sweat-collecting materials.

Family-based prevention in youth's substance misuse in low- and middle-income countries: A review from Turkey and cultural adaptation of family based interventions.

Family-based interventions have been recognized and practised more in high-income countries than in low- and middle-income countries. However, the threats posed by substance misuse to the youth do not change for the latter. The development of appropriate preventive programs is an area of interest for addiction prevention in low- and middle-income countries by recognizing the risk factors for substance misuse among young individuals.

Toxicological evaluation of alcohol and substance abuse in children and adolescents.

Unhealthy behaviors such as use of alcohol and drug usually begin during adolescence. Izmir is on transit route for illicit substance due to geographical situation. Children and adolescents are the most important threatened group in terms of alcohol and substance abuse.

The impact of creatinine reference value: Normalization of urinary drug concentrations.

Many illicit drug users attempt to manipulate urine drug testing; dilution is one of the methods. In screening tests, false-negative results below the cut-off values can create positive results after creatinine normalization. This study aimed to evaluate the impact of a creatinine reference value on the normalization of the drug concentration in diluted urine.

Determination of synthetic cannabinoids in randomly urine samples collected from probationers in Turkey.

Synthetic cannabinoids are a significant public health and safety problem that complicates drug tests with their ever-changing structures in our country and worldwide. The fact that most synthetic cannabinoids cannot be detected in biological samples by routine drug of abuse screening tests also causes an increase in the use of these substances in return. In this study, 500 urine samples of randomly selected probationers, analyzed with an enzymatic immunoassay test at Ege University Institute of Drug Addiction, Toxicology and Pharmaceutical Sciences (BATI) and tested negative, were then selected for retrospective analysis.

Urine drug-testing tampering approaches: Turkish probationers.

The growing numbers of individual and social problems associated with drug abuse necessitate new approaches in drug-testing systems. Equally, drug abusers may attempt to invalidate drug testing using different methods such as adulteration, dilution and substitution. This study aims to investigate tampering methods commonly used by Turkish substance-using probationers and evaluate their effects on toxicological drug-testing results.

Morphine Concentrations in Human Urine Following Poppy Seed Paste Consumption.

Papaver somniferum (opium poppy) is one of the world's oldest medicinal plants which are widely used for medicinal, nutritive and scientific purposes. Turkey is one of the major legal opium poppy producer countries in the world and the seed paste of the poppies is consumed in great deal, even more than 100g per meal. The main objective of this study is to investigate the influence of poppy seed paste ingestion on urine tests for opiates whether or not could lead to opiate positive urine test results.

Legal workplace policies for drugs and alcohol in Turkey.

The widespread of individual and social problems related to substance use/abuse provoked the new approaches for workplace drug testing systems in the world. Workplace drug testing laws are constructed to protect the community from the consequences of drug use by workers. In Turkey, the legal arrangements on workplace drug testing exist in Turkish Penal Code, Turkish Labour Law, Workplace Physicians Regulations, Maritime Labour Law and Medical Examination Instructions in Highway Transportation Although Turkey has made the initial attempts to develop homogeneous and reliable regulations for workplace drug testing, a detailed workplace policy for drug testing at workplace has still not been provided.
