Synthetic cannabinoids (SC), are a novel class of designer drugs which emerged as a drug of abuse in the late 2000's. We report a case series of 6 patients who may have smoked a synthetic cannabinoid product in a remote wilderness setting. They presented with varying degrees of altered mental status, agitation, and seizures. Two were confirmed to have AB-PINACA, ADB-PINACA and their respective pentanoic acid metabolites in biological specimens via liquid chromatography time-of-flight mass spectrometry (LC-TOF/MS)...

BACKGROUND: Unintentional tetrahydrocannabinol (THC) exposure in pediatric patients can present as altered mental status. Altered mental status in a pediatric patient often leads to invasive diagnostic testing. CASE REPORT: The following cases describe 3 pediatric patients in Washington state who presented to a tertiary care children's hospital emergency department (ED) with altered mental status, later found to have urine toxicology screening positive for inactive THC metabolite (positive THC toxicology screen)...

In utero exposure to marijuana may cause various short- and long-term health problems, such as stillbirth, low birth weight and decreased cognitive function. Detection of in utero marijuana exposure with a relatively new specimen type, umbilical cord tissue, can be used to plan treatment and guide social management. In this study, a liquid chromatography-tandem mass spectrometry (LC-MS-MS) assay was developed for the simultaneous identification of four cannabinoids in umbilical cord tissue, including ∆9-tetrahydrocannabinol (THC), 11-nor-9-carboxy-∆9--THC (THC-COOH), 11-hydroxy-∆9-THC (11-OH-THC) and cannabinol (CBN)...

According to 2014 National Survey on Drug Use and Health, 5.3% of pregnant women smoked marijuana in the past month. This prevalence is expected to increase as a growing number of states and countries are now considering legalization. Although umbilical cord is becoming a useful objective tool to detect in utero drug exposure, currently data about analytical methods and its utility to detect cannabis exposure are scarce. The objective of this work was to develop a method for the determination of Δ(9) -tetrahydrocannabinol (THC), 11-hydroxyTHC (THC-OH), 11-nor-9-carboxy-THC (THCCOOH), 8-β-11-dihydroxyTHC (THC-diOH), THC and THCCOOH glucuronides, and cannabidiol (CBD) in umbilical cord by liquid chromatography-tandem mass spectrometry (LC-MS-MS) with dual ionization source...

Given the necessity to better understand the process patients need to go through in order to seek treatment via medical marijuana, this study investigates this process to better understand this phenomenon. Specifically, Compassion Care Foundation (CCF) and Stockton University worked together to identify a solution to this problem. Specifically, 240 new patients at CCF were asked to complete a 1-page survey regarding various aspects associated with their experience prior to their use of medicinal marijuana-diagnosis, what prompted them to seek treatment, level of satisfaction with specific stages in the process, total length of time the process took, and patient's level of pain...

Among new psychoactive substances (NPS) available on the narcotic market, a significant number consists of synthetic cannabinoids commonly known as smokable herbal "spice" and "K2", and which are legally treated as a legal alternative to marijuana. The dearth of information on the pharmacology of these intoxicants as they are introduced into the market has created the urgent need among healthcare providers for case studies on the substances belonging to this group, both in terms of the consequences of using such intoxicants, and in methods of detection...

BACKGROUND: Although, especially in the United States, there has been a recent surge of legalized cannabis for either recreational or medicinal purposes, surprisingly little is known about clinical dose-response relationships, pharmacodynamic and toxicodynamic effects of cannabinoids such as Δ9-tetrahydrocannabinol (THC). Even less is known about other active cannabinoids. METHODS: To address this knowledge gap, an online extraction, high-performance liquid chromatography coupled with tandem mass spectrometry method for simultaneous quantification of 11 cannabinoids and metabolites including THC, 11-hydroxy-Δ9-tetrahydrocannabinol, 11-nor-Δ9-tetrahydrocannabinol-9-carboxylic acid, 11-nor-Δ9-tetrahydrocannabinol-9-carboxylic acid glucuronide (THC-C-gluc), cannabinol, cannabidiol, cannabigerol, cannabidivarin, Δ9-tetrahydrocannabivarin (THCV), and 11-nor-9-carboxy-Δ9-tetrahydrocannabivarin (THCV-COOH) was developed and validated in human urine and plasma...

Synthetic cannabinoids are sprayed onto plant material and smoked for their marijuana-like effects. Clandestine manufacturers modify synthetic cannabinoid structures by creating closely related analogs. Forensic laboratories are tasked with detection of these analog compounds, but targeted analytical methods are often thwarted by the structural modifications. Here, direct analysis in real time coupled to accurate mass time-of-flight mass spectrometry (DART-TOF-MS) in combination with liquid chromatography quadruple time-of-flight mass spectrometry (LC-QTOF-MS) are presented as a screening and nontargeted confirmation method, respectively...

BACKGROUND: The use of marijuana for medical purposes is now legal in some U.S. states and other jurisdictions, such as Canada, and Israel. Despite the widespread legalization of medical marijuana globally, there is limited information on patterns and correlates of medical marijuana use (MMU). We conducted a literature review to assess prevalence, reasons, perceived effects, and correlates of MMU among adolescents and adults. METHODS: We searched peer-reviewed articles in English between January 1996 and August 2016 from several databases (PubMed, Google Scholar, Embase, CINAHL, and PsycINFO) using different combinations of keywords...

REVIEW
David E Mandelbaum, Suzanne M de la Monte
The growing use and legalization of cannabis are leading to increased exposures across all age groups, including in adolescence. The touting of its medicinal values stems from anecdotal reports related to treatment of a broad range of illnesses including epilepsy, multiple sclerosis, muscle spasms, arthritis, obesity, cancer, Alzheimer disease, Parkinson disease, post-traumatic stress, inflammatory bowel disease, and anxiety. However, anecdotal data and the high level of interest in this treatment must not obscure objective assessments of any potential and realized short- and long-term adverse effects of cannabis, particularly with respect to age of onset and chronicity of exposure...

Marijuana is the most commonly used illicit drug in Canada, with 10% of the general population admitting to its use in the past year. This high prevalence increases risk of accidental ingestion in young children. We report four pediatric cases of accidental marijuana ingestion who presented to our local emergency department with altered mental status. Three patients had extensive testing, including one patient who underwent lumbar puncture and empirical treatment for meningitis. To our knowledge, this is the first Canadian case series since McNabb et al...
