Newest firstHexahydrocannabinol (HHC) is a semi-synthetic cannabinoid that has recently emerged in the European market, raising concerns regarding its detection in forensic toxicology. Reliable analytical approaches are required for the determination of HHC metabolites together with conventional cannabis biomarkers in biological samples. This study aimed to develop and validate a sample preparation method based on air-assiste…
Open article record in new tab ↗This study investigates the prevalence of substance use among victims and perpetrators involved in clinical forensic cases. Urine samples from 455 individuals aged 18 and above, collected in 2019, were analyzed using two LC-MS-based analytical methods and an HS-GC-FID method for the most frequently reported substances of abuse and medication. Data from case documents, encompassing gender, age, and the individual's…
Open article record in new tab ↗The aim was to investigate the suitability of Santhica 27 industrial hemp leaves as a protein source in dairy cow nutrition. Twelve Holstein dairy cows received a total mixed ration (TMR) containing 7.4% industrial hemp leaves (HEMP) and a TMR containing 3.5% soya extraction meal (CON) in a crossover design. Cows were kept in a free-stall barn for 2 weeks to measure feed intake, milk yield and sample plasma, rumin…
Open article record in new tab ↗The laboratory analysis of new psychoactive substances and related drugs is crucial for accurate clinical and forensic diagnosis of poisonings. Given this, a new LC-MS/MS method for analyzing hallucinogens, synthetic cathinones, and synthetic cannabinoids in urine was developed. Urine samples were extracted using a liquid-liquid extraction protocol optimized via a multivariate experimental design. An aliquot of 40…
Purpose Cannabidiol (CBD) products are widely used for pain relief, sleep improvement, management of seizures etc. Although the concentrations of Δ9-tetrahydrocannabinol (Δ9-THC) in these products are low (≤0.3% w/w), it is important to investigate if its presence and/or that of its metabolite 11-nor-carboxy-Δ9-THC, is traceable in plasma and urine samples of individuals who take CBD oil products. Methods A sensit…
Importance Young children are ingesting illicit drugs at increased rates, but it is unknown what the associated child protection system (CPS) responses are when a child tests positive. Objective To document the child protection system involvement and the characteristics of children who test positive for illicit substances. Design, setting, and participants This retrospective cross-sectional study linked medical di…
Cannabis is frequently detected in forensic investigations and is associated with an increased risk of fatal car crashes. This study aims to develop a method to detect and measure ∆9-tetrahydrocannabinol (∆9-THC) in blood and its metabolite, 11-nor-9-tetrahydrocannabinol-carboxylic acid (∆9-THC-COOH), in urine. The procedure employs two liquid-liquid extraction methods in conjunction with GC-MS in SIM mode. Both c…
Open article record in new tab ↗BackgroundAn increasing prevalence of alcohol consumption is a major public health problem, which has also led to an increasing number of children who have been prenatally exposed to the toxic effects of ethanol. However, obtaining reliable information on prenatal alcohol exposure through maternal self-reports has proved difficult.AimsOur aim was to evaluate the potential for rapid screening test for measuring eth…
Open article record in new tab ↗Cannabis is the most consumed illicit drug worldwide, and its legal status is a source of concern. This study proposes a rapid procedure for the simultaneous quantification of Δ9-tetrahydrocannabinol (THC), 11-hydroxy-Δ9-tetrahydrocannabinol (11-OH-THC), 11-nor-9-carboxy-Δ9-tetrahydrocannabinol (THC-COOH), cannabidiol (CBD), and cannabinol (CBN) in urine samples. Microextraction by packed sorbent (MEPS) was used t…
Background and Objectives: The use of synthetic cannabinoids has increased around the world. As a result, the implementation of accurate analysis in human biological matrices is relevant and fundamental. Two different analytical technologies, ultra-high-performance liquid chromatography-high-resolution mass spectrometry (UHPLC-HRMS) and high-sensitivity gas chromatography-mass spectrometry (GC-MS) were used for th…
Cannabis products have been used for centuries by humans for recreational and medical purposes. Resent research, proposed the promising therapeutic potential of cannabis and related cannabinoids for a wide range of medical conditions, including psychiatric and neurological diseases. This Special Issue presents the latest updates on medicinal cannabis and synthetic cannabinoids pharmacology, toxicology and new anal…
Open article record in new tab ↗Changes in lipid metabolism are involved in several pathological conditions, such as cancer. Among lipids, eicosanoids are potent inflammatory mediators, synthesized from polyunsaturated fatty acids (PUFAs), which coexist with other lipid-derived ones, including endocannabinoids (ECs) and N-acylethanolamides (NAEs). In this work, a bioanalytical assay for 12 PUFAs/eicosanoids and 20 ECs/NAEs in cell culture medium…
Background:Cannabis is one of the most widely used illicit drugs in India and worldwide. It is considered to have a minimal effect on physical health.Objectives:The aim of this study was to compare the laboratory profiles of treatment-seeking patients who were cannabis dependent, and drug users who concurrently use other substances, with non-users.Materials and Methods:Medical records of patients, whose urine was…
