TL;DR: In this paper, thermal desorption direct analysis in real-time mass spectrometry (TD-DART-MS) and ion mobility spectrometer (IMS) was used for the rapid and sensitive detection of fentanyl, 16 fentanyl analogues, and five additional opioids.

TL;DR: This technique has proven to be efficient for the one step extraction from hair of different classes of NPS in routine toxicological investigations; from unstable and volatile compounds, such as most of the cathinones, to hydrophobic compounds such as synthetic cannabinoids.

TL;DR: It could be possible to suggest pulp/tooth area ratio calculation from first, upper canines and other single rooted teeth (lower premolars, upper central incisors), and a specific statistical analysis that considers the non-linear production of secondary dentine with age, as a reliable, easy, faster, and predictable method for dental age estimation in adults.

TL;DR: In this study, two fatalities associated with the synthetic opioids AH-7921 and MT-45 are reported and deaths of the young individuals could be, by exclusion of other causes of death, attributed to the consumption of an overdose of AH- 7921 andMT-45.

TL;DR: This paper critically presents the state of the art in regards to GSR interpretation in a holistic manner and proposes an alternative approach that allows an evaluation of the evidence that is more closely aligned to judicial and investigative aims.

TL;DR: Five cases of acute intoxication by synthetic cannabinoids 5F-ADB and MMB-2201 with analytical confirmation are reported with analytical confirm.

TL;DR: Three deaths can be explained as a direct consequence of consumption of synthetic cannabinoids, although in case one and two relevant amounts of ethanol were found, and in case three trimipramine and olanzapine were present in non-toxic concentrations.

TL;DR: This study provides useful comparative data for decomposition and insect succession pattern of human cadaver with animal carcasses.

TL;DR: Variation in juvenile growth patterns of populations and differences in adult skeletal size and characteristics are discussed, recognizing variation should be considered by forensic anthropologists when estimating sex from skeletal remains and appropriate population-specific data should be utilized.

TL;DR: The data suggest that GHB-associated deaths are increasing in London, and that this is likely at least in part due to increasing use of GHB for chemsex.

TL;DR: The calculation of THC/CBD ratios in both herbal and resin samples confirms the recent change in chemotypes in favor of high potency categories and was measured in order to evaluate the freshness of French seized hemp.

TL;DR: The geographical analysis reveals that spatial patterns on Evolution tend to reflect the structure of the traditional illicit market, and regarding illicit drugs, country-specificity has been observed and are presented in this article.

TL;DR: The Nolla and Demirjian methods were found to be accurate in estimating chronological age from dental age in a Spanish population, and combined methods affords a predictive capacity of over 99%, and is fast and easy to perform, and inexpensive.

TL;DR: An efficient way of copy-move forgery detection (CMFD) through local binary pattern variance (LBPV) over the low approximation components of the stationary wavelets is presented to address the possible post processing operations in a better way.

TL;DR: Evaluation of the Raman spectra showed that increasing the excitation wavelength from 785 to 1064nm improved this 'first pass' NPS identification primarily due to a significant reduction in fluorescence, which increased S/N of the characteristic peaks of the substance identified.

TL;DR: Data for the total number of 263 fire death cases in the Mazowieckie region (mainly Warsaw area) of Poland between 2003-2011 for dwellings fires were obtained from pathologists, forensic toxicologists, fire fighters and analysed.

TL;DR: Humanitarian forensic action is the application of the knowledge and skills of forensic medicine and science to humanitarian action, especially following conflicts or disasters.

TL;DR: Overall, the applicability of ILs as promising solvents for the extraction of benzodiazepines in whole blood samples has been proven and a fast and easy IL-based DLLME procedure was developed for the quantification of 19 Benzodiazepine-like hypnotics.

TL;DR: Micro-CT as a forensic radiological method provided vital information and the basis for visualisation both during the investigation and in the subsequent trial making it one of the first examples of such technology in a UK court.

TL;DR: The results show that even extremely high mitragynine blood concentrations following the consumption of kratom do not necessarily have to be the direct cause of death in such fatalities as a result of an acute overdose.

TL;DR: To identify soil microbiota communities involved in human decomposition through high-throughput sequencing of DNA sequences from the different bacteria, to monitor quantitatively and qualitatively the decay of such signature species, and to describe succesional changes in bacterial populations from the early putrefaction state until skeletonization.

TL;DR: The present characteristics of the Swedish drug market for fentanyl-analogs in general and acrylfentanyl in particular are discussed, reporting a structural difficulty to effectively counteracting the appearance of unscheduled substances due to the constant turnover of new molecules on the recreational drug market.

TL;DR: The established approach succeeded in identifying the index number and the manufacturer of the samples by using an in-lab built ATR spectra library and demonstrates a great potential for the differentiation and identification of red lipsticks with a very similar hue.

TL;DR: This case study of acute furanyl fentanyl overdose in a young male thought to be using oxycodone highlights illicit drug users are often subject to unknown drug entities.

TL;DR: This method is suitable for assessing the attainment of legal age of adulthood in Saudi population and the cut-off value of I3m is similar to other populations.

TL;DR: Blood samples from 48 cases of suspected intoxications were collected during autopsy at the Department of Forensic Medicine in Stockholm, Sweden and confirmed the results from previous studies that drug concentrations in central blood are generally higher than in peripheral blood.

TL;DR: The aims of this work were to optimize and validate a GC-MS method for the quantitative determination of anabolic steroids in tablet, aqueous suspension and oil solution forms, and to analyze pharmaceutical products sent to Brazilian Federal Police for forensic analysis.

TL;DR: The potential of applying microbial ecology methodologies in soil as an evaluative forensic tool is illustrated by applying RISA and 16S rRNA gene sequencing with Illumina Miseq.

TL;DR: Although the death occurred by drowning, the prosecutor requested toxicological exams, in order to evaluate the potential role of drugs of abuse in the episode, and the 25C-NBOMe levels measured in the subject's blood are considered potentially toxic.
