The recent increase in reports of drug-facilitated sexual assaults has caused alarm in the general public and prompted forensic toxicologists from across North America to address the toxicological issues surrounding this matter. The authors have developed recommendations and guidelines to inform law enforcement, medical, and scientific personnel of the requirements for performing successful toxicological examinations in cases of drug-facilitated rape.

Ethanol analysis is the most frequently performed assay in forensic toxicology laboratories. Interpretation of postmortem ethanol findings are often confounded by postmortem production of ethanol. Many species of bacteria, yeast, and molds are capable of producing ethanol from a variety of substrates. The probability of postmortem ethanol synthesis increases as storage temperature and the interval between death and autopsy increases. It is often difficult to distinguish between postmortem ethanol production and antemortem alcohol ingestion. This review presents a discussion of the criteria for the identification of postmortem ethanol synthesis and factors to consider in the interpretation of postmortem ethanol findings. The criteria include case history, condition of the specimens, types of microbes present, atypical fluid and tissue distribution of ethanol, the concentration of ethanol present, and the detection of other alcohols and volatiles. With careful consideration of all the information available, a valid interpretation of the source of ethanol, whether it be from antemortem ingestion or postmortem production, can be made.

Objective A new class of synthetic hallucinogens called NBOMe has emerged as drugs of abuse. Our aim was to conduct a systematic review of published reports of toxicities associated with NBOMe ingestion. Methods We searched the PubMed for relevant English language citations that described adverse effects from analytically confirmed human NBOMe ingestion. Demographic and clinical data were extracted. Results Ten citations met criteria for inclusion, representing 20 individual patients. 25I-NBOMe was the most common analog identified, followed by 25B-NBOMe and 25C-NBOMe. Fatalities were reported in 3 (15%) cases. Seven (35%) were discharged after a period of observation, while 8 (40.0%) required admission to an intensive care unit. The most common adverse effects were agitation (85.0%), tachycardia (85.0%), and hypertension (65.0%). Seizures were reported in 8 (40.0%) patients. The most common laboratory abnormalities were elevated creatine kinase (45.0%), leukocytosis (25.0%), and hyperglycemia (20.0%). Conclusion NBOMe ingestion is associated with severe adverse effects. Clinicians need to have a high index of suspicion for NBOMe ingestion in patients reporting the recent use of hallucinogens.

Personal battery-powered vaporizers or electronic cigarettes were developed to deliver a nicotine vapor such that smokers could simulate smoking tobacco without the inherent pathology of inhaled tobacco smoke. Electronic cigarettes and their e-cigarette liquid formulations are virtually unregulated. These formulations are typically composed of propylene glycol and/or glycerin, flavoring components and an active drug, such as nicotine. Twenty-seven e-cigarette liquid formulations that contain nicotine between 6 and 22 mg/L were acquired within the USA and analyzed by various methods to determine their contents. They were screened by Direct Analysis in Real Time™ Mass Spectrometry (DART-MS). Nicotine was confirmed and quantitated by high-performance liquid chromatography-tandem mass spectrometry, and the glycol composition was confirmed and quantitated by gas chromatography-mass spectrometry. The DART-MS screening method was able to consistently identify the exact mass peaks resulting from the protonated molecular ion of nicotine, glycol and a number of flavor additives within 5 mmu. Nicotine concentrations were determined to range from 45 to 131% of the stated label concentration, with 18 of the 27 have >10% variance. Glycol composition was generally accurate to the product description, with only one exception where the propylene glycol to glycerin percentage ratio was stated as 50:50 and the determined concentration of propylene glycol to glycerin was 81:19 (% v/v). No unlabeled glycols were detected in these formulations.

Context Abuse of synthetic stimulant compounds resulting in significant toxicity is being increasingly reported by poison centers. Toxicologic assessment is complicated by inconsistent manufacturing processes and limited laboratory testing. We describe a case of self-reported exposure to 25-I (25I-NBOMe), a novel phenethylamine derivative, with subsequent quantification in serum. Case details An 18-year-old male presented to the emergency department (ED) with severe agitation and hallucinations after jumping out of a moving car. He was tachycardiac (150–160 bpm) and hypertensive (150–170 mm Hg systolic and 110 mg Hg diastolic), and required physical restraints and treatment with intravenous lorazepam administration. His symptoms gradually improved and vital signs returned to normal over 48 h, though he continued to have episodes of aggressiveness. An assay was developed by our analytical toxicology laboratory for 25-I, and serum obtained during ED evaluation and treatment was found to contain 0.76 ng/ml of 25-I. Case discussion For 25I-NBOMe, 25-I is a common abbreviation for 25I-NBOMe, which is a (n-benzyl) phenethylamine in the 2C “family.” Initially synthesized for research, cases of self-reported use of 25-I have recently appeared in the literature, some of which contain qualitative urine conf rmation. There are no commercially available quantitative assays, and no previous reports have published serum concentrations. 25-I is a potent new synthetic drug with apparent significant behavioral toxicity that can be detected and quantified in serum.
