The other side of the paper as the evidence: impacts of fingermark development reagents on fingermark development and cocaine amount in cocaine-impregnated paper.

Despite various preventative measures, cocaine smuggling is still a major problem worldwide. A recent method of smuggling is the transportation of cocaine with various chemicals or with impregnated materials such as cloth and paper. This study aims to examine the change in the amount of cocaine on the paper surface and attempts to decide the best fingermark development method in the case of smuggling trafficking in the form of impregnated paper with the least effect on the cocaine concentration on the paper.

Optimization of biochip assay for illegal substances on drug abusers' whole blood: Randox Evidence vs LC-MS/MS.

Immunoassay tests are used in clinical and forensic toxicology laboratories to determine illicit drug use in biological samples. Therefore, this study aims to optimize the cutoff concentrations of DOA I Plus in the blood and compare the LC-MS/MS results. 680 authentic forensic whole blood specimens with Randox Evidence DOA I Plus array were screened for drug of abuse and confirmed by LC-MS/MS.

Determination of phosphatidyl ethanol (PEth) 16:0/18:1 in dried blood samples of drivers involved in traffic accidents: A pilot study.

In routine forensic toxicology practices, blood alcohol concentration (BAC) levels are measured in traffic accidents that ended up in emergency departments. Nevertheless, since the elimination of ethanol from the blood is fast and the detection time is short, BAC cannot indicate the occurrence of chronic excessive alcohol consumption. Phosphatidylethanol (PEth) is a unique ethanol direct biomarker that occurs only in the presence of phospholipase D enzyme in erythrocyte membranes during alcohol intake, and it indicates alcohol intake.

Comparison of methods to develop fingerprints on papers impregnated with AB-PINACA and AB-FUBINACA.

Although there have been significant advances in fingerprinting techniques, studies on how these techniques affect other criminal evidence are limited. Synthetic cannabinoids (SC), which are illegal substances frequently encountered in crime scenes and are widely used worldwide, are available in various forms in the market (pill, powder, liquid, and herbal product). These synthetic cannabinoid substances have recently been introduced to places such as prisons and rehabilitation centers, primarily via an infused piece of paper.

Determination of AB-FUBINACA and 5F-NPB-22 in rats exposed to "Bonsai" via inhalation and analysis of seized product.

Synthetic cannabinoids (SCs) are the most rapidly growing class of recreational designer drugs. Illicit drug manufacturers began to produce herbal smoking materials under a variety of brands names, e.g.
