Background: A wide range of novel psychoactive substances (NPS) is regularly searched and discussed online by web-based drug enthusiasts (i.e. the e-psychonauts). Among NPS, the range of synthetic cannabinoids (SC; ‘Spice’) currently represents a challenge for governments and clinicians. Methods: Using a web crawler (i.e. the NPS.Finder®), the present study aimed at assessing psychonauts’ fora/platforms to better understand the online mentions of SC. Results: The open-web crawling/navigating software identified here some 1,103 synthetic cannabinoids. Of these, 863 molecules were not listed in either the international or the European NPS databases. Conclusions: A web crawling approach helped here in identifying a large range of unknown SC likely to possess a misuse potential. Most of these novel/emerging molecules are still relatively unknown. This is a reason for concern; each of these analogues potentially presents different toxicodynamic profiles and there is a lack of docking, preclinical, and clinical observations. Strengthening multidisciplinary collaboration between clinicians and bioinformatics may prove useful in better assessing SC-associated public health risks.

IntroductionComorbidities between psychiatric diseases and consumption of traditional substances of abuse are common. Nevertheless, there is no data regarding the use of novel psychoactive substances (NPS) in the psychiatric population.ObjectivesThe purpose of this multicentre survey is to investigate the consumption of a wide variety of psychoactive substances in a young psychiatric sample.MethodsBetween September 2013 and November 2015, a questionnaire has been administered, in ten Italian psychiatric care facilities, to a sample of 671 psychiatric patients (48.5% men; 51.5% women), aged between 18 and 26 years (mean age: 22.24).Results8.2% of the sample declared use of NPS at least once in a lifetime and 2.2% have assumed NPS in the last three months. The NPS more used were synthetic cannabinoids (4.5%), followed by methamphetamine (3.6%). The three psychiatric diagnosis with more frequent NPS consumption were bipolar disorder (23.1%), personality disorders (11.8%) and schizophrenia and related disorders (11.6%). Bipolar disorder was associated with NPS consumption (P < .001). Among the illicit drugs investigated, 31.4% of the sample was cannabis smoker and 10.7% cocaine user. Moreover, 70.6% of the sample declared alcohol use and 47.7% had binge drinking conducts. In univariate regression analysis, bipolar disorder was positive associated with binge drinking while obsessive compulsive disorder resulted negative associated.ConclusionsThe use of novel psychoactive substances in a young psychiatric population appears to be a frequent phenomenon, probably still underestimated. Bipolar disorder shows an association with NPS use. Therefore, careful and constant monitoring and accurate evaluations of possible clinical effects related to their use are necessary.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract New psychoactive substances (NPS) are a major public health problem, primarily due to the increased number of acute poisoning cases. Detection of these substances is a challenge. The aim of this research was to develop and validate a sensitive screening method for 104 drugs of abuse, including synthetic cannabinoids, synthetic cathinones, fentanyl analogues, phenethylamines and other abused psychoactive compounds (i.e., THC, MDMA, LSD and their metabolites) in oral fluid by liquid chromatography–tandem mass spectrometry (LC–MS-MS). The Quantisal™ oral fluid device was used to collect oral fluid samples. The oral fluid–elution buffer mixture (500-μL sample) was extracted with t-butyl methyl ether, and chromatographic separation was performed on a Raptor™ biphenyl column (100 × 2.1 mm ID, 2.7 μm), with a total run time of 13.5 min. Limits of detection were established at three concentrations (0.05, 0.1 or 1 ng/mL) for most analytes, except for acetyl norfentanyl and mescaline (5 ng/mL). Matrix effects were generally &lt;20% and overall extraction recoveries &gt;60%. The highest matrix effect was observed within the synthetic cannabinoid group (PB22, −55.5%). Lower recoveries were observed for 2C-T (47.2%) and JWH-175 (58.7%). Recoveries from the Quantisal™ device were also evaluated for all analytes (56.7–127%), with lower recoveries noted for 25I-NBOMe, valerylfentanyl and mCPP (56.7, 63.0 and 69.9%, respectively). Drug stability in oral fluid was evaluated at 15, 60 and 90 days and at 25, 4 and −20°C. As expected, greater stability was observed when samples were stored at −20°C, but even when frozen, some NPS (e.g., synthetic cannabinoids) showed more than 20% degradation. The method was successfully applied to the analysis of seven authentic oral fluid samples positive for 17 different analytes. The method achieved good sensitivity and simultaneous detection of a wide range of NPS.

BACKGROUND: The prevalence of use and misuse of novel psychoactive substances (NPS) has been escalating at an exponential rate in the past two decades. Studies on NPS are highly concentrated in relevance to the developed world, while few have been undertaken in the developing countries.MATERIALS & METHODS: This study is observational and cross-sectional in nature; it relies on a web-based survey distributed to a population of (ab)users of psychedelics and NPS; this community was accessible via dedicated online platforms psychedelics users located on the Facebook social communication medium. The aim of the study is to estimate the level of knowledge and the extent of (mis)use in connection with psychoactive substances, including the novel ones (NPS).RESULTS: The number of participants who responded to the survey reached 458 responders. The level of knowledge and (ab)use was relatively high. The majority of participating individuals were Caucasians males from the developed world including the US, the UK, India, and western European countries. The primary religious affiliation was either agnosticism or atheism. Approximately, 26% were diagnosed with the neuropsychiatric condition.CONCLUSION: The NPS phenomenon is still a major concern primarily in the developed world. Additional studies are required in virtual and non-virtual populations. The targeted populations should include; students, medical professionals, academics, patients with psychiatric and neurological abnormalities, convicts and criminals, and even terrorists.

Novel psychoactive substances (NPS) represent a severe health risk for drug users. Even though the phenomenon has been growing since the early 2000s, the mechanisms of action of NPS at the receptors and beyond them are still scarcely understood. The aim of the present study was to provide a systematic review of the updated knowledge regarding the molecular mechanisms underlying the toxicity of synthetic opioids, cannabinoids, cathinones, and stimulants. The study was conducted on the PubMed database. Study eligibility criteria included relevance to the topic, English language, and time of publication (2010–2020). A combined Mesh and free-text protocols search was performed. Study selection was performed on the title/abstract and, in doubtful cases, on the full texts of papers. Of the 580 records identified through PubMed searching and reference checking, 307 were excluded by title/abstract and 78 additional papers were excluded after full-text reading, leaving a total of 155 included papers. Molecular mechanisms of synthetic opioids, synthetic cannabinoids, stimulants, psychedelics, and hallucinogens were reviewed and mostly involved both a receptor-mediated and non-receptor mediated cellular modulation with multiple neurotransmitters interactions. The molecular mechanisms underlying the action of NPS are more complex than expected, with a wide range of overlap among activated receptors and neurotransmitter systems. The peculiar action profile of single compounds does not necessarily reflect that of the structural class to which they belong, accounting for possible unexpected toxic reactions.

Direct analysis in real time mass spectrometry (DART-MS) is an increasingly employed tool for a wide range of forensic applications including seized drug analysis. A significant body of research surrounds DART-MS for the analysis of seized drugs and how it can be used to address many of the challenges caused by the increased presence of emerging drugs and novel psychoactive substances. A lack of available resources to help address validation, operation, training, and data interpretation needs is just one of the hurdles that laboratories face when adopting new technologies, such as DART-MS. To provide additional resources to assist in validation development, this work provides a template that can be adopted or adapted for DART-MS or other ambient ionization mass spectrometry techniques for qualitative seized drug analysis. The template, which was created as a result of recent implementation efforts, provides a description of validation studies with a focus on understanding the potential challenges and limitations caused by the prevalence of novel psychoactive substances and other emerging drugs. The studies address accuracy and precision, reproducibility, specificity, sensitivity, environmental factors, use in casework, and robustness. In addition to providing a template for validation, the results obtained from completing these studies on two high-resolution DART-MS systems are also presented. This work, and the corresponding supplemental information, was created to add to the available resources that laboratories can leverage to assist in overcoming the adoption hurdles of ambient ionization mass spectrometry methods such as DART-MS.

Abstract Synthetic Cannabinoids (SC) are amongst the most prevalent class of novel psychoactive substances (NPS) which have emerged. The increase in hospitalisation and fatalities as a result of the prevalence of these SC and their abuse, highlights the necessity for the rapid and reliable screening for the substance within toxicological samples. Being able to rapidly screen for these substances would aim to improve overdose triage and ultimately improve treatment administration. Not only this but it would have further advantages for in-field applications such as the identification of drivers under the influence. To this avail we investigate the ability of a simple electrochemical screening strategy for the detection of SC, BB-22 and its primary metabolite BB-22-3-Carboxyindole. Assessment of the feasibility of the strategy for implementation into toxicological sample analysis was performed through detection not only under ideal electrolyte conditions (down to 5 µM for BB-22 and 2 µM for its metabolite) but also within the complex biological matrix of human pooled serum (between 200 and 700 µM), a relevant matrix it would likely encounter if employed within this field.

С появлением на нелегальном рынке наркотиков новых психоактивных веществ, одно из первых в данном классе стали занимать синтетические каннабиноиды (СК). СК в основном распространяются через сеть Интернет, с помощью онлайн мессенджеров, и VPN-сетей. Токсическое влияние СК на организм человека оказывается достаточно мощным и нередко заканчивается летальным исходом. Однако аддиктивный потенциал СК достаточно высок, и нуждается в дальнейшем изучении, особенно с появлением новых классов СК. Разработка дифференциально-диагностических критериев и терапевтических подходов при лечении острых психотических состояний, вызванных употреблением СК, представляется актуальной задачей для практического здравоохранения. Цель: обзор накопленных научных данных о последствиях рекреационного употребления СК на организм человека. Материалы: при написании обзора использовали следующие репрезентативные базы данных: PubMed, Google Scholar, Embase, Cochrane, платформы SciFinder, и Scopus. Методы: в качестве поисковых запросов использовались следующие ключевые слова: Spice, K2, synthetic cannabis, new psychoactive sub-stances (NPS), adverse effects, cannabinoid’s receptor, psychosis due to the use NPS, fatalities. Реферируемые статьи были отфильтрованы по тезисам, с целью определения релевантности для настоящего обзора. With the emergence of novel psychoactive substances in the illegal drug market, synthetic cannabinoids (SCs) became one of the first in this class. SCs are mainly distributed through the Internet, by online messengers and VPN networks. The toxic effect of SCs on the human body is quite powerful and often results in death. The addictive potential of SCs is rather high and needs further study, especially with the emergence of new SC classes. Development of differential diagnostic criteria and therapeutic approaches in the treatment of acute psychotic conditions caused by the use of SCs is an urgent task for practical health care. Objective: to review scientific data on consequences of the recreational use of SCs in humans. Materials: data from six representative databases, PubMed, Google Scholar, Embase, Cochrane, the SciFinder platform, and Scopus, were used for this review. Methods: the following combinations and keywords were used as search queries: Spice, K2, synthetic cannabis, novel psychoactive substances (NPS), adverse effects, cannabinoid’s receptor, psychosis due to the use of NPS, fatalities. Peer-reviewed articles were filtered by abstracts to determine their relevance for the present review.

Abstract Issue In a prison in Scotland, an increasing number of incidents occurred where staff became unwell secondary to potential exposure to novel psychoactive substances (NPS) smoked by prisoners. There were high levels of concern for the safety of individual staff, and for establishment staffing. NPS use is a significant problem in custodial settings, and impacts individuals and establishments. Methods HMP and HPT led an incident response: HMP focused on prevention and direct management of incidents; HPT focused on exposure circumstances, clinical presentation and toxicological testing of symptomatic staff. A protocol was agreed between all agencies involved. Over 8 months, all incidents’ initial assessment and any subsequent clinical and toxicological results were collated and analysed by HPT. Results There were 19 incidents involving 16 staff members. Cases presented in clusters, in one instance 13 people presented over 5 days. Five presented in early 2018. Individuals reported a wide range of non-specific physical and psychological effects; some cases experienced severe impairment of day-to-day function. The most common effects were headache and fatigue but some reported sleep disturbance and confusion lasting up to 72 hrs. There were no significant clinical observations at hospital, and the 3 tests for toxicology were negative. Lessons The individuals affected by these incidents experienced physical and psychological distress, and impairment of daily functioning which impacted on the safe function of the establishment. It is unlikely staff presentations were due to toxicological effects from substances used by prisoners. It is possible their symptoms were psychosomatic. This could be further investigated, and consideration given to supportive intervention for staff affected by exposure to NPS. The investigation demonstrated excellent collaborative work between the prison, health services, and forensic laboratories in a novel investigation into NPS exposure in prisons. Key messages NPS use, and subsequent exposure to staff, is a growing issue in custodial settings. A combination of supportive interventions for staff, including reduction and mitigation of risk of exposure to NPS, plus control of substances use in prisons can help.
