Self-discharge during treatment for acute recreational drug toxicity: an observational study from emergency departments in seven European countries. Int J Emerg Med 2023; 16:86. [PMID: 38030969 PMCID: PMC10685690 DOI: 10.1186/s12245-023-00566-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Accepted: 11/22/2023] [Indexed: 12/01/2023] Open
Abstract
BACKGROUND Self-discharge is a risk factor for readmission and excess mortality. We assess the rate of self-discharge from the emergency department (ED) among presentations for acute recreational drug toxicity and identify factors associated with self-discharge. METHODS From the Euro-DEN Plus database of presentations to the ED with acute recreational drug toxicity, we extracted data from 11 centres in seven European countries from 2014 to 2017. Self-discharge was defined as taking one's own discharge or escaping from the ED before being medically cleared. We used multiple logistic regression analyses to look for factors associated with self-discharge. RESULTS Among 15,135 included presentations, 1807 (11.9%) self-discharged. Self-discharge rates varied from 1.7 to 17.1% between centres. Synthetic cannabinoids were associated with self-discharge, adjusted odds ratio 1.44 (95% confidence interval 1.10-1.89), as were heroin, 1.44 (1.26-1.64), agitation, 1.27 (1.10-1.46), and naloxone treatment, 1.27 (1.07-1.51), while sedation protected from self-discharge, 0.38 (0.30-0.48). CONCLUSION One in eight presentations self-discharged. There was a large variation in self-discharge rates across the participating centres, possibly partly reflecting different discharge procedures and practices. Measures to improve the management of agitation and cautious administration of naloxone to avoid opioid withdrawal symptoms may be approaches worth exploring to reduce self-discharge.

The chemistry and toxicology of vaping. Pharmacol Ther 2021; 225:107837.

Abstract
Vaping is the process of inhaling and exhaling an aerosol produced by an e-cigarette, vape pen, or personal aerosolizer. When the device contains nicotine, the Food and Drug Administration (FDA) lists the product as an electronic nicotine delivery system or ENDS device. Similar electronic devices can be used to vape cannabis extracts. Over the past decade, the vaping market has increased exponentially, raising health concerns over the number of people exposed and a nationwide outbreak of cases of severe, sometimes fatal, lung dysfunction that arose suddenly in otherwise healthy individuals. In this review, we discuss the various vaping technologies, which are remarkably diverse, and summarize the use prevalence in the U.S. over time by youths and adults. We examine the complex chemistry of vape carrier solvents, flavoring chemicals, and transformation products. We review the health effects from epidemiological and laboratory studies and, finally, discuss the proposed mechanisms underlying some of these health effects. We conclude that since much of the research in this area is recent and vaping technologies are dynamic, our understanding of the health effects is insufficient. With the rapid growth of ENDS use, consumers and regulatory bodies need a better understanding of constituent-dependent toxicity to guide product use and regulatory decisions.

Abstract
Synthetic cannabinoid (SC) use has persisted in the United States despite schedule-1 placement under the Synthetic Drug Abuse Prevention Act of 2012 [1]. Analysis of the National Poison Data System indicates that hospitalisations caused by SC use increased significantly between 2010 and 2015 [2]. Moreover, there is a trend of the increasing use of such compounds among adolescents [3]. SCs are often 30–100-fold more potent than Δ9-tetrahydrocannabinol (THC), the major psychoactive ingredient of cannabis, in activating Cannabinoid receptor 1 (CB1R). Users are attracted to SCs because of the cheaper, novel and stronger highs such substances offer compared to cannabis, and because the compounds are not screened for in typical drug tests [1, 2]. Among those hospitalised for SC use, some patients exhibited respiratory failure [4–7], pulmonary infiltrates [5, 7], alveolar damage or haemorrhage [5–7] and histopathologic features similar to organising pneumonia [4–6]. The mechanism by which SCs damage pulmonary tissue has yet to be elucidated – whether by SC binding at CB1R, CB2R or another receptor, and what downstream effects such binding elicits. Solving this conundrum is the first step in optimising treatment for patients presenting with SC-related respiratory distress. Synthetic cannabinoids (SCs) induce a pro-inflammatory condition by activating cannabinoid receptor 1 (CB1R) in the lungs of mice, which raises a potential therapeutic use of CB1R antagonists in SC-induced lung disease resulting in hospitalisationhttps://bit.ly/31bWw4Q

Abstract
OBJECTIVES This study aims to examine patterns and first mentions of reported use of new or uncommon drugs across 13 years, among nationally representative samples in the United States. METHODS Participants (ages ≥12) in the National Surveys on Drug Use and Health (2005-2017, N = 730,418) were provided opportunities to type in names of new or uncommon drugs they had ever used that were not specifically queried. We examined self-reported use across survey years and determined years of first mentions. RESULTS From 2005 to 2017, there were 2,343 type-in responses for use of 79 new or uncommon synthetic drugs, and 54 were first-ever mentions of these drugs. The majority (65.8%) of mentions were phenethylamines (e.g., 2C-x, NBOMe), which were also the plurality of new drug mentions (n = 22; 40.7%). Mentions of 2C-x drugs in particular increased from 30 mentions in 2005 to 147 mentions in 2013. We estimate an upward trend in use of new or uncommon drugs between 2005 and 2017 (p < 0.001). CONCLUSION Although type-in responses on surveys are limited and underestimate prevalence of use, such responses can help inform researchers when new compounds are used. Continued surveillance of use of new and uncommon drugs is needed to inform adequate public health response.
