Case Report of Methylone, Oxymorphone and Ethanol in a Fatality Case with Tissue Distribution.

It is reasonable to expect the presence of multiple drugs to present a complicated picture of toxicity. We report a fatal case involving a young man who purchased illicit drugs and knowingly consumed them. After consuming these drugs and going to sleep in his friend's car, he was found unresponsive the next morning with no signs of physical violence.

Detection of 25C-NBOMe in Three Related Cases.

An accidental death associated with the use of the designer drug, 2-(4-chloro-2,5-dimethoxyphenyl)-N-(2-methoxybenzyl)ethanamine (25C-NBOMe), is reported. A 23-year-old Caucasian male experienced severe respiratory distress and died after being subdued by military law enforcement. At autopsy, remarkable findings upon internal examination included mild to moderate coronary atherosclerosis, biventricular dilation, mild right ventricular hypertrophy and bilateral pulmonary edema and congestion.

Ultrafast Screening of Synthetic Cannabinoids and Synthetic Cathinones in Urine by RapidFire-Tandem Mass Spectrometry.

Screening for emerging drugs of abuse, specifically synthetic cathinones and synthetic cannabinoids, is difficult for high-throughput laboratories as immunoassay kits are often unavailable. Consequently, most laboratories employ liquid chromatography-tandem mass spectrometry (LC-MS-MS) screening, which can be complex and time consuming as these techniques may require involved sample preparation and lengthy analysis times. The increasing demand for novel psychoactive substance testing necessitates alternative screening methods that are sensitive, fast and versatile.

Analysis of Parent Synthetic Cannabinoids in Blood and Urinary Metabolites by Liquid Chromatography Tandem Mass Spectrometry.

Synthetic cannabinoids emerged on the designer drug market in recent years due to their ability to produce cannabis-like effects without the risk of detection by traditional drug testing techniques such as immunoassay and gas chromatography-mass spectrometry. As government agencies work to schedule existing synthetic cannabinoids, new, unregulated and structurally diverse compounds continue to be developed and sold. Synthetic cannabinoids undergo extensive metabolic conversion.

A sensitive GC-EIMS method for simultaneous detection and quantification of JWH-018 and JWH-073 carboxylic acid and hydroxy metabolites in urine.

Synthetic cannabinoids, including JWH-018 and JWH-073, belong to a class of aminoalkylindoles (AAIs) that are smoked to produce an effect similar to tetrahydrocannabinol. Compounds in this class are often collectively known as 'Spice'. After ingestion, these compounds are extensively metabolized to their hydroxy and carboxylic acid metabolites.

Determination of designer drug cross-reactivity on five commercial immunoassay screening kits.

The detection of new designer drugs is often a difficult issue in forensic urine drug testing as immunoassays are the primary screening methodology for drugs of abuse in many of these laboratories. Cross-reactivity of compounds with immunoassay kits can either aid or complicate the detection of a variety of drug and drug metabolites. For instance, emerging designer drugs that share structural similarities to amphetamines and phencyclidine (PCP) have the potential to cross-react with assays designed to detect these compounds.

Multidrug toxicity involving sumatriptan.

A multidrug fatality involving sumatriptan is reported. Sumatriptan is a tryptamine derivative that acts at 5-HT(1B/1D) receptors and is used for the treatment of migraines. The decedent was a 21-year-old white female found dead in bed by her spouse.

Evaluation of designer amphetamine interference in GC-MS amine confirmation procedures.

In recent years, a class of new designer drugs commonly referred to as 'bath salts' have made their way to the illicit drug market. The most common drugs encountered are designer amphetamines and cathinones. Many analytical methods for analysis and identification of bath salts have been published, but there has been little reported on their impact on existing gas chromatography-mass spectrometry (GC-MS) amine confirmation methods.

A fatality involving AH-7921.

A case is presented of a 19-year-old white male who was found dead in bed by a friend. While no anatomic cause of death was observed at autopsy, toxicological analysis of his blood identified AH-7921, a synthetic opioid. AH-7921 was isolated by liquid-liquid extraction into n-butyl chloride from alkalinized samples.

Evaluation of abalone β-glucuronidase substitution in current urine hydrolysis procedures.

This study examined the potential of abalone β-glucuronidase as a viable and cost effective alternative to current hydrolysis procedures using acid, Helix pomatia β-glucuronidase and Escherichia coli β-glucuronidase. Abalone β-glucuronidase successfully hydrolyzed oxazepam-glucuronide and lorazepam-glucuronide within 5% of the spiked control concentration. Benzodiazepines present in authentic urine specimens were within 20% of the concentrations obtained with the current hydrolysis procedure using H.

Delta9-tetrahydrocannabinol content of commercially available hemp products.

Delta9-Tetrahydrocannabinol (THC) is the main psychoactive compound present in marijuana. THC can also be found, as a contaminant, in some commercially available hemp products marketed in health food stores and on the internet as a good source of essential fatty acids. The products range from oil to alcoholic beverages to nutritional bars to candies, with oil being the most popular and commonly available.

The detection and quantitative analysis of the psychoactive component of Salvia divinorum, salvinorin A, in human biological fluids using liquid chromatography-mass spectrometry.

Salvia divinorum, a member of the mint plant family, has hallucinogenic properties that have become increasingly sought after by recreational drug users. The main psychoactive component, salvinorin A, has potency comparable to lysergic acid diethylamide. Though still legal to possess in most of the United States and much of Europe, little is known regarding the compound's long-term health effects, addiction liability, and pharmacokinetics.

Quantitative and isomeric determination of amphetamine and methamphetamine from urine using a nonprotic elution solvent and R(-)-alpha-methoxy-alpha-trifluoromethylphenylacetic acid chloride derivatization.

Forensic Urine Drug Testing Laboratories often requires two confirmatory methods for a methamphetamine positive screen. First, methamphetamine is identified and quantitated using gas chromatography-mass spectrometry. If the total methamphetamine concentration is above the administrative cutoff level, the isomeric composition must be determined.

Concentration profiles of cocaine, pyrolytic methyl ecgonidine and thirteen metabolites in human blood and urine: determination by gas chromatography-mass spectrometry.

When cocaine is smoked, a pyrolytic product, methyl ecgonidine (anhydroecgonine methyl ester), is also consumed with the cocaine. The amount of methyl ecgonidine formed depends on the pyrolytic conditions and composition of the illicit cocaine. This procedure describes detection of cocaine and 10 metabolites--cocaethylene, nor-cocaine, nor-cocaethylene, methyl ecgonine, ethyl ecgonine, benzoylecgonine, nor-benzoylecgonine, m-hydroxybenzoylecgonine, p-hydroxybenzoylecgonine and ecgonine--in blood and urine.

Comparison of the Microgenics CEDIA heroin metabolite (6-AM) and the Roche Abuscreen ONLINE opiate immunoassays for the detection of heroin use in forensic urine samples.

Current Department of Defense (DoD) and Department of Health and Human Services (HHS) procedures for the detection of heroin abuse by testing urine utilize an initial opiate (codeine/morphine) immunoassay (IA) screen followed by gas chromatography-mass spectrometry (GC-MS) confirmation of 6-acetylmorphine (6-AM), if the morphine concentration is above established cutoff. An alternative to the current opiates screen for heroin abuse is the direct IA for the metabolite of heroin, 6-acetylmorphine. In this regard, the performance of the Microgenics CEDIA heroin metabolite (6-AM) screening reagent was assessed.
