Introduction

In 2024, full structure elucidation was achieved for a novel synthetic cathinone, N-cyclohexyl pentylone. Synthetic stimulants, including cathinones, represent the largest group of NPS and are increasingly dominating the global drug market. These compounds have diverse structures that are difficult to rapidly identify and characterise using screening methods which rely on database comparisons. Due to the rapidly changing landscape of NPS, drug laboratories are struggling to keep up with the rate at which these novel substances are appearing.

Methods

The Institute of Environmental Science and Research (ESR) provides assistance to Drug Checking Service providers in instances where identification in the field is unsuccessful. Where a novel substance or structural isomers are encountered, techniques including high-resolution MS and NMR spectroscopy are employed. Results/

Conclusions

Characterisation of N-cyclohexylpenylone was achieved and has since been detected on several occasions within New Zealand. This NPS has also emerged in the U.S, demonstrating the need for the development of an analytical strategy for the rapid detection and identification of newly emerging NPS to effectively assist in the protection of public health. It also highlights the need for effective data sharing within the Forensic Community.
在2024年,一个新的合成卡西酮,n -环己基戊酮的完整结构被阐明。包括卡西酮在内的合成兴奋剂是NPS中最大的一类,并日益主导着全球毒品市场。这些化合物具有不同的结构,难以使用依赖于数据库比较的筛选方法快速识别和表征。由于NPS的快速变化,药物实验室正在努力跟上这些新物质出现的速度。方法环境科学与研究所(ESR)在现场鉴定不成功的情况下,向药品检查服务提供者提供协助。当遇到新的物质或结构异构体时,采用高分辨率质谱和核磁共振波谱等技术。结果/结论n -环己基penylone已被鉴定,并在新西兰境内多次检测到。美国也出现了这种新型非传染性疾病,这表明有必要制定一种分析策略,以快速发现和识别新出现的非传染性疾病,从而有效地协助保护公众健康。它还强调了在法医界内部有效共享数据的必要性。

Introduction

Kratom (Mitragyna speciosa), a tropical plant from the coffee family native to Southeast Asia, has a long history of use as a traditional herbal remedy, particularly for pain relief and mood enhancement. While its opioid-like effects have raised concerns about dependence, emerging research suggests that certain kratom alkaloids also interact with the brain’s serotonin system. Notably, some alkaloids may bind to 5-HT receptors, opening potential avenues for treating conditions such as anxiety, depression, and schizophrenia.

Methods

In this study, we employed molecular docking and computer simulations to explore how kratom-derived alkaloids interact with serotonin receptors—particularly the 5-HT1A subtype.

Results

We found that mitragynine, kratom’s principal psychoactive compound, exhibits a higher binding affinity to the 5-HT1A receptor than ajmalicine and binds at a distinct site on the receptor, suggesting a unique mechanism of action. By analyzing these structural interactions, we identified key molecular features influencing receptor affinity.

Conclusions

Our findings shed light on how kratom alkaloids may modulate serotonergic signaling and support the development of novel kratom-based therapeutics targeting neuropsychiatric disorders.
kratom (Mitragyna speciosa)是一种原产于东南亚的咖啡科热带植物,作为一种传统的草药治疗有着悠久的历史,特别是用于缓解疼痛和改善情绪。虽然其类似阿片类药物的作用引起了人们对依赖性的担忧,但新兴研究表明,某些克拉托姆生物碱也与大脑的血清素系统相互作用。值得注意的是,一些生物碱可能与5-羟色胺受体结合,为治疗焦虑、抑郁和精神分裂症等疾病开辟了潜在的途径。方法在本研究中,我们采用分子对接和计算机模拟的方法来探索克拉木衍生的生物碱如何与血清素受体相互作用,特别是5-HT1A亚型。结果我们发现,米特拉金(kratom的主要精神活性化合物)与5-HT1A受体的结合亲和力高于ajmalicine,并且结合在受体的不同部位,表明其独特的作用机制。通过分析这些结构相互作用,我们确定了影响受体亲和力的关键分子特征。结论我们的研究结果揭示了kratom生物碱如何调节血清素能信号,并支持了基于kratom的新型神经精神疾病治疗方法的开发。

The majority 52% were either high school or college leavers. 86% trusted online resources for information regarding vaping and only 32% referred to healthcare professionals. 81% stated that reliable online resources would work best as the main source of information. 62% of participants were tobacco smokers, and only 21% were ex-smokers. A total of 46% started e-vaping at 25 years or above; 60% used vapes daily. 72% had frequent or occasional cravings to vape; 37% tried to stop unsuccessfully. Meanwhile 31% complained about adverse events after vaping such as coughing, weakness, dizziness, sore throat, chest pain, palpitations, anxiety, COPD.

New substances, new psychoses 新的物质,新的精神病
Pub Date : 2025-12-01 DOI: 10.1016/j.etdah.2025.100196
G. Bersani
Consensual clinical experience indicates that in recent years the spread of an increasingly large and heterogeneous number of psychoactive substances is leading to substantial changes in the phenomenology and course of mental disorders, particularly psychotic disorders. NPS play a central role in this change and contribute, in a powerful yet highly variable manner, to the presence of previously undescribed clinical entities. The clinical constructs of Substance Use Disorder and Dual Diagnosis now appear insufficient to describe the breadth and complexity of the phenomenon. Some new clinical categories have been described, not yet included in official nosographic systems, such as spiceophrenia, synthetic psychosis, lysergic psychoma, hallucinogen persistent perceptual disorder, and others, in an attempt to recognize clinical forms of highly variable psychopathological conditions. In fact, the traditional diagnostic categories of psychiatry, particularly those of psychotic disorders and mood disorders, no longer appear capable of realistically describing the clinical variability of the psychopathological pictures of psychotic patients. Furthermore, it is necessary to consider the marked clinical and outcome changes that the widespread use of psychoactive substances induces in the clinical presentations of patients already suffering from mental disorders, so that the clinical presentations of, for example, schizophrenia or bipolar disorder very often appear significantly altered in their symptomatology and course. On a strictly clinical level, certain psychopathological features appear more consistently associated with the use of psychoactive substances, such as greater severity of paranoid symptoms, high frequency of exacerbations, mood instability, dysregulation of emotions and behavior, early cognitive decline, and resistance to traditional pharmacological treatments. This is a clinical landscape of enormous significance, which shows how the clinical presentations and diagnostic categories of traditional psychiatry have progressively and severely changed.
双方同意的临床经验表明,近年来,越来越多的数量各异的精神活性物质的传播正在导致精神障碍,特别是精神障碍的现象学和病程发生实质性变化。NPS在这一变化中发挥了核心作用,并以一种强大但高度可变的方式,促成了以前未描述的临床实体的存在。物质使用障碍和双重诊断的临床结构现在似乎不足以描述这种现象的广度和复杂性。一些新的临床类别已被描述,但尚未包括在官方的疾病分类系统中,如香料性精神分裂症、合成精神病、麦角性精神瘤、致幻剂持续性知觉障碍等,试图识别高度可变的精神病理状况的临床形式。事实上,传统的精神病学诊断范畴,特别是精神障碍和情绪障碍的诊断范畴,似乎不再能够真实地描述精神病患者精神病理图像的临床变异性。此外,有必要考虑到精神活性物质的广泛使用在已经患有精神障碍的患者的临床表现中引起的明显的临床和结果变化,因此,例如精神分裂症或双相情感障碍的临床表现往往在其症状和病程上出现显著改变。在严格的临床层面上,某些精神病理特征似乎与精神活性物质的使用更一致地相关,例如更严重的偏执症状、更频繁的恶化、情绪不稳定、情绪和行为失调、早期认知能力下降以及对传统药物治疗的抵抗。这是一个具有巨大意义的临床图景,它显示了传统精神病学的临床表现和诊断类别是如何逐渐和严重地改变的。

Introduction

Benzodiazepines are a widely prescribed medication used to treat anxiety, panic disorders, insomnia and seizures. The misuse of this class of drugs in Ireland has increased over the last eight years with a 70% increase in persons participating in drug treatment programmes being treated for benzodiazepines as the main problem. A recent publication from the Health Research Board (HRB) indicated that benzodiazepines and related NPS were implicated in more than 50% of drug poisoning deaths in Ireland in 2021.

Methods

Data collated from Forensic Science Ireland’s (FSI) LIMS system show that FSI receives, on average, almost 700,000 seized benzodiazepine type tablets each year since 2019. Legitimate pharmaceutical presentations are submitted for analysis as well as falsified (fake) pharmaceutical presentations.

Results

Data showing the seizure trends during this timeline of many different drugs and NPS will be presented. The changes to the controlled drug law in Ireland and how these have influenced this market will also be presented.

Conclusions

Many falsified (fake) pharmaceutical tablets were encountered during this period.
苯二氮卓类药物是一种广泛用于治疗焦虑、惊恐障碍、失眠和癫痫发作的处方药。在过去八年中,爱尔兰滥用这类药物的情况有所增加,参加药物治疗方案的人因苯二氮卓类药物作为主要问题而接受治疗的人数增加了70%。健康研究委员会(HRB)最近的一份出版物表明,苯二氮卓类药物和相关的NPS与2021年爱尔兰50%以上的药物中毒死亡有关。方法从爱尔兰法医科学(FSI) LIMS系统整理的数据显示,自2019年以来,FSI平均每年收到近70万片缉获的苯二氮卓类药片。合法的药品演示文稿和伪造的(假)药品演示文稿一起提交进行分析。结果本文将介绍不同药物和NPS在这段时间内的缉获趋势。还将介绍爱尔兰管制毒品法的变化以及这些变化如何影响这一市场。结论在此期间发现了许多伪造(假药)片剂。

Introduction

Throughout history, mushrooms have served as a bridge for ancient populations, guiding human beings from earthly life to the "Beyond" and allowing them to "taste" this passage during their lifetime, thereby alleviating the fear of death.

Methods

Recent scientific research has revealed that these ancient practices are supported by research done by leading world universities showing the effectiveness of psilocybin mushrooms in addressing fear of death, anxiety, and existential stress. As consequence psilocybin is now allowed and its use regulated, in several countries, as treatment in individuals with terminal cancer and other similar conditions.

Results

The experience of guiding a person across the bridge between life and death raises intriguing questions about the nature of consciousness, the potential for communication in "non-ordinary states of consciousness" between different realms of nature, and the possibility of transcending space and time, thereby creating a new experience and continuity between life and death.

Conclusions

Although we advocate for a wider and more accessible of use of psylocibin in the end of life we believe that more studies are necessary to identify the subjects that would benefit the most from this practice.
纵观历史,蘑菇一直是古代人群的桥梁,引导人类从尘世生活到“来世”,让他们在有生之年“品尝”这一段,从而减轻对死亡的恐惧。最近的科学研究表明,这些古老的做法得到了世界一流大学的研究的支持,这些研究表明裸盖菇素在解决对死亡的恐惧、焦虑和存在压力方面的有效性。因此,在一些国家,裸盖菇素现在被允许作为晚期癌症和其他类似疾病患者的治疗药物,其使用受到监管。结果引导一个人跨越生与死之间的桥梁的体验引发了一些有趣的问题,包括意识的本质、不同自然领域之间“非普通意识状态”的交流潜力,以及超越时空的可能性,从而在生与死之间创造一种新的体验和连续性。结论:尽管我们提倡在生命末期更广泛、更方便地使用心虫素,但我们认为有必要进行更多的研究,以确定从这种做法中获益最多的受试者。

Deaths Following Tianeptine Use in the UK 在英国使用天奈汀后的死亡
Pub Date : 2025-12-01 DOI: 10.1016/j.etdah.2025.100245
E. Mshari, C. Copeland

Introduction

Tianeptine is an atypical tricyclic antidepressant with opioid receptor agonist properties. It is unlicensed in the UK. The FDA has released public health warnings on its adverse effects, including dependence, overdose, and mortality. Here we present the characteristics of the first four deaths following tianeptine use in the UK.

Methods

Cases with post-mortem detections of tianeptine were extracted from the National Programme on Substance Use Mortality (NPSUM) and analysed.

Results

Four deaths with post-mortem detections of tianeptine were reported to the NPSUM by 1st November 2024 (male n=2, female n=2; age range 29-51). The first death occurred in 2019, with the following three in 2023. Two deaths were concluded as drug-related, one as suicide, and one as misadventure. Post-mortem analyses identified polydrug use in all cases, with hypnotics/sedatives co-detected in three cases, opioids in two cases, other antidepressants in two cases, and gabapentinoids in two cases.

Conclusions

These are the first documented deaths following tianeptine use in the UK, highlighting its emergence on the UK illicit drug market. All cases involved polydrug use, underscoring the risks of combining tianeptine with other CNS depressants. Tianeptine poses a potential public health concern that warrants monitoring, regulation, and increased clinical awareness.
天奈汀是一种具有阿片受体激动剂特性的非典型三环抗抑郁药。它在英国没有执照。美国食品和药物管理局已经发布了关于其副作用的公共卫生警告,包括依赖、过量和死亡。在这里,我们介绍了在英国使用天奈肽后的前四例死亡的特征。方法从国家药物使用死亡率报告(NPSUM)中提取死后检测到天奈肽的病例并进行分析。结果截至2024年11月1日,共报告4例尸检检出替奈汀死亡病例(男2例,女2例,年龄29 ~ 51岁)。第一例死亡发生在2019年,接下来的三例发生在2023年。两起死亡的结论是与毒品有关,一起是自杀,还有一起是意外事故。尸检分析发现,所有病例均使用多种药物,其中3例同时使用催眠药/镇静剂,2例使用阿片类药物,2例使用其他抗抑郁药,2例使用加巴喷丁类药物。结论:这是英国首次记录的使用天奈肽后的死亡病例,突显了它在英国非法药物市场上的出现。所有病例都涉及多种药物的使用,强调了将天奈肽与其他中枢神经系统抑制剂联合使用的风险。天奈肽引起潜在的公共卫生问题,需要监测、管理和提高临床意识。

Masculinity, Media, and Muscle: IPEDs and the Double-Edged Role of Online Platforms 男性气质、媒体与肌肉:iped与网络平台的双刃剑角色
Pub Date : 2025-12-01 DOI: 10.1016/j.etdah.2025.100260
H.D. Townshend

Introduction

This presentation will explore the intersection of masculinity, image and performance enhancing drugs (IPEDs) use, and digital culture. Specifically, it will interrogate how online platforms operate as complex spaces that simultaneously reinforce harmful gendered body ideals and facilitate harm reduction practices among men who use IPEDs.

Methods

This mixed-methods research comprised a five-month netnography of bodybuilding forums and a follow-up cross-sectional survey incorporating open-ended responses and visual data. Thematic analysis was applied to both datasets, with attention to gender theory and body image. A thematic analytic framework was applied, informed by contemporary gender theory and literature on embodiment, subcultural capital, and digitally-mediated drug practices.

Results

Findings demonstrate that masculinities articulated online are often aligned with hegemonic, hyper-muscular ideals, reinforcing normative body anxieties and legitimizing substance use. However, these same digital forums also function as decentralized harm reduction spaces, where peer-led knowledge exchange, risk mitigation strategies, and emotional support are routinely enacted.

Conclusions

Online platforms should be understood as ambivalent cultural sites: they reproduce and circulate dominant masculine aesthetics while simultaneously hosting community-based harm reduction. This duality has significant implications for drug policy, health communication, and the development of targeted interventions within digitally embedded subcultures.
本演讲将探讨男性气质、形象和表现增强药物(iped)的使用和数字文化的交集。具体来说,它将探讨在线平台如何作为复杂的空间运作,同时强化有害的性别身体理想,并促进使用iped的男性减少伤害的做法。方法这项混合方法的研究包括对健身论坛进行为期5个月的网络调查,以及一项包含开放式回答和视觉数据的后续横断面调查。主题分析应用于两个数据集,注意性别理论和身体形象。采用了一个专题分析框架,该框架由当代性别理论和关于具体化、亚文化资本和数字媒介药物实践的文献提供信息。研究结果表明,网上表达的男性气概往往与霸权主义、肌肉发达的理想相一致,强化了规范的身体焦虑,并使物质使用合法化。然而,这些数字论坛也可以作为分散的减少伤害空间,在这里,同行领导的知识交流、风险缓解战略和情感支持经常被制定出来。结论网络平台应被理解为一种矛盾的文化场所:它们复制和传播占主导地位的男性美学,同时举办以社区为基础的减少伤害活动。这种二元性对药物政策、卫生传播和数字嵌入亚文化中有针对性干预措施的发展具有重大影响。

From Traditional Use to Dependence: Investigating the Neurobiological Impact of Kratom and Mitragynin 从传统使用到依赖:研究克拉托姆和米特拉格宁的神经生物学影响
Pub Date : 2025-12-01 DOI: 10.1016/j.etdah.2025.100228

Introduction

Kratom (Mitragyna speciosa) and its primary alkaloid, mitragynine, have gained global attention as plant-derived psychoactive substances with stimulant and opioid-like properties. Traditionally used in Southeast Asia for medicinal purposes and as a stimulant among manual laborers, kratom has more recently emerged in Western contexts as a recreational "herbal high" and alternative to opioids. Despite its long-standing cultural use, concerns about its potential for misuse, particularly among adolescents seeking euphoric effects, have intensified. However, an overdose of kratom may cause addiction-like problems, including aversive withdrawal states and developing physical dependence. Research has found that mitragynine can lead to physical dependence when taken repeatedly and changes how brain cells work.

Methods

Here, we compared the impact of kratom decoction relative to mitragynine in terms of its physical dependence and its underlying brain cellular mechanism. We also investigated the significance of kratom intoxication for physical dependence in the future treatment of kratom addiction. Results/

Conclusions

While local communities may still view kratom as harmless, emerging scientific evidence underscores its capacity to impair cognitive function and contribute to dependence, raising important questions for public health, regulation, and future research.
米特拉金(Mitragyna speciosa)及其主要生物碱米特拉金碱(mitragynine)作为具有兴奋剂和阿片类药物特性的植物源性精神活性物质已引起全球关注。传统上,kratom在东南亚被用作药用和体力劳动者的兴奋剂,最近在西方语境中作为一种娱乐性的“草药兴奋”和阿片类药物的替代品出现。尽管大麻在文化上的使用由来已久,但对其可能被滥用的担忧,特别是在寻求欣快效果的青少年中,已经加剧。然而,过量服用克瑞托姆可能会导致类似成瘾的问题,包括令人厌恶的戒断状态和身体依赖。研究发现,反复服用米特ragynine会导致身体依赖,并改变脑细胞的工作方式。方法比较克拉通煎剂与米特拉金的生理依赖性及其潜在的脑细胞机制。我们还探讨了苦参中毒对未来苦参成瘾治疗中身体依赖的意义。虽然当地社区可能仍然认为kratom是无害的,但新出现的科学证据强调了它损害认知功能并导致依赖的能力,这为公共卫生、监管和未来研究提出了重要问题。

Introduction

Ephedrine and its analogs are reportedly encountered in seized samples of drugs of abuse. It is also reported as a precursor in the clandestine manufacture of methamphetamines in India. The present research presents a sensitive color test for the detection of ephedrine in forensic samples.

Methods

The certified reference materials (CRM) for the pharmaceutical compounds were sourced from the Indian Pharmacopoeia, Ghaziabad, India. Corresponding working standards of the drugs were prepared, and the developed colorimetric assay was further optimized to enable precise execution at reduced scales. The analytical method was validated following the parameters outlined in the International Council for Harmonisation (ICH) guidelines, ensuring its specificity, accuracy, and reproducibility.

Results

The test solutions exhibited a violet coloration upon interaction with ephedrine. The colorimetric assay was assessed through visual evaluation of color development, and key reaction parameters influencing the chromatic response were systematically optimized. The validated method met the requisite criteria for preliminary screening applications, ensuring the generation of qualitative and dependable presumptive test results.

Conclusions

The refined analytical method demonstrates high sensitivity, reproducibility, and robustness, effectively detecting ephedrine at a threshold of 7.5 µL. Validation studies affirm that the distinct colorimetric shift is unique to ephedrine under ambient conditions, remains unaltered in the presence of common adulterants, and maintains stability across alkaline pH levels of 12–14. Its rapid and selective performance makes it an efficient screening tool for forensic applications, ensuring reliable qualitative detection in routine analytical assessments.
据报道,在查获的滥用药物样本中发现麻黄碱及其类似物。据报道,它也是印度秘密制造甲基苯丙胺的前体。本研究提出了一种检测法医样品中麻黄碱的灵敏显色法。方法经认证的标准物质(CRM)来源于印度加济阿巴德的印度药典。制备相应的药物工作标准,并进一步优化所建立的比色法,使其能够在小尺度下精确执行。该分析方法按照国际统一理事会(ICH)指南中概述的参数进行验证,确保其特异性、准确性和可重复性。结果实验溶液与麻黄碱相互作用后呈现紫色。通过显色视觉评价法对比色法进行评价,并对影响显色反应的关键反应参数进行系统优化。经过验证的方法满足初步筛选应用的必要标准,确保生成定性和可靠的推定测试结果。结论该方法灵敏度高,重现性好,鲁棒性好,可在7.5µL的阈值下有效检测麻黄碱。验证研究证实,在环境条件下,麻黄碱具有独特的比色变化,在常见掺假物的存在下保持不变,并在12-14的碱性pH水平下保持稳定。其快速和选择性的性能使其成为法医应用的有效筛选工具,确保在常规分析评估中可靠的定性检测。
