Psychoactive Substances

Novel psychoactive substances (NPS) are popular “club/party” drugs that first attracted attention in the UK in 2009 and remained legal until the 2016 Psychoactive Substances Act criminalized their distribution. Unlike “traditional” illicit drugs, very little is known about the influence of their analogs on neuropsychological functioning. We characterized the cognitive and emotional profile of NPS/polydrug users using the Cambridge Neuropsychological Test Automated Battery (CANTAB) and EMOTICOM test battery in adult male (aged 20–49 years) recreational users without psychiatric comorbidities (n = 27; “psychonauts”), service users attending a UK specialist “Club Drug” Clinic for problematic use (n = 20) and healthy control volunteers without significant drug-taking histories (n = 35). Tasks were selected to distinguish “hot” cognitive processes that are highly influenced by emotion from “cold” cognitive processes that are largely independent of emotional influence. Both user groups reported significantly higher sensation-seeking traits compared with non-users. Recreational NPS users demonstrated more risk-taking behavior compared with controls and treatment-seeking NPS users showed poorer learning, episodic memory and response inhibition compared with the other two groups. These effects persisted, when controlling for age, intelligence, alcohol and cannabis use severity, nicotine dependence, trait anxiety, depression, childhood adversity, impulsivity, and sensation seeking. Overall, recreational NPS users showed elevated “hot” (emotion-laden) cognition in the absence of “cold” (non-emotional) cognitive deficits, whereas “cold” cognitive dysfunction was pronounced in individuals seeking treatment for problematic NPS use. High trait impulsivity and poor self-control may confer additional risk to NPS/polydrug use severity and separate those seeking treatment from those using NPS recreationally.

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.

Objective. Over the last few years, a wide number of unregulated substances have been marketed on the Web and in smart and head shops; they are usually advertised as legal alternatives to commonly known drugs and are defined as “smart drugs,” “legal highs,” and “novel psychoactive substances” (NPS). Aim of our work is to describe use habits and distribution of NPS in a population of young adults in Rome club scene.Methods. A self-administered questionnaire was proposed to subjects over 18 years of age at the entrance of 5 nightclubs in Rome. Socioeconomic characteristics and substance use were investigated.Results. Preliminary results give evidence that 78% of respondents have a lifetime history of NPS use. In addition, 56% of the sample has consumed illicit drugs in the past and 39% has used psychoactive substances in the 12 hours preceding the questionnaire administration.Conclusions. A significant proportion of subjects report use of novel psychoactive substances; traditional illicit drugs consumption, particularly cocaine, appears to be very high as well in the club scene. These data highlight a serious public health challenge, since pharmacological, toxicological, and psychopathological effects linked to interactions among all these substances may be unpredictable and sometimes fatal in vulnerable individuals.

Microbiological Aspects

Wastewater-based epidemiology has emerged as a new analytical strategy for monitoring licit and illicit drug use in a population by measuring the levels of biomarkers in wastewater. The main concept of this approach is that chemical substances ingested by the population will be excreted in urine and feces, which will be discarded into the sewage network and may accumulate at the wastewater treatment plant. Several licit and illicit substances such as ethanol, nicotine, cocaine, amphetamine, methamphetamine and morphine have been investigated and reported in wastewater in worldwide. In recent years, this approach has also been explored for environmental monitoring of novel psychoactive substances (NPS) as well, since analyses of wastewater represent a fast and cost-effective way to evaluate collectively drug intake in a given population served by a sewage network. In this paper, a comprehensive and interdisciplinary review of the forensic, toxicological, chemical and microbiological aspects of the analysis of “traditional” drugs of abuse and NPS in wastewater and examples of applications reported in recently published papers is provided. Wastewater analysis is a very promising strategy in monitoring drug use in the context of Forensic Chemistry and Toxicology, and has been implemented by many researchers in the analysis of drugs of abuse, as supported by many recent literature reports.

Background and aims Novel psychoactive substances are compounds intended to mimic the effects of illicit drugs. They provide a unique challenge to healthcare, as complications of their use and their impact on services are relatively unknown. This study aims to determine nature of presentations, patient demographics and impact on healthcare. Methods Novel psychoactive substances users who presented to a large urban emergency department over 4 weeks were prospectively identified and followed for 1 year. Patients over 13 years old were eligible for inclusion. Information regarding patient demographics and presentations was collected. Results During the study period, 53 patients (39 male), mean age 32.6 ± 8.9 (±standard deviation), presented 148 times with complaints relating to novel psychoactive substances use. Study population characteristics included history of illicit drug use (83.0%), intravenous drug use (64.2%), psychiatric diagnosis or symptoms (56.6%), methadone prescription (52.8%) and having no fixed abode (37.7%). Injection was the most common method of use (72.3%), Burst the most commonly named agent (19.6%) and behavioural change the most common presenting complaint (31.1%). Patients collectively spent 10,620 h in hospital over 1 year. Conclusion This study highlights differences between the young population targeted by government campaigns regarding novel psychoactive substances use and the presenting population to hospital, and the associated burden on the National Health Service.

Questo articolo nasce dall'esigenza di informare un pi&ugrave; ampio pubblico sul pericolo rappresentato da queste sostanze, far conoscere le NPS (Novel Psychoactive substances) agli operatori del settore (personale di laboratorio, personale delle unit&agrave; di emergenza/ urgenza, operatori sanitari, ricercatori, ecc.) al fine di agevolare l'analisi di campioni sconosciuti e divulgare i dati scientifici che cominciano ad emergere da studi clinici e preclinici sui loro effetti tossici e farmacologici.&nbsp;Dal 2009 sono comparsi nel gruppo delle N.P.S., i nuovi oppioidi sintetici, molecole estremamente potenti che comportano una seria minaccia per la salute pubblica. Si tratta di prodotti dalla notevole potenza (il fentanyl, per esempio, capostipite di questa famiglia, ha un'azione circa 100 volte maggiore rispetto a quella della morfina) che vengono utilizzati sia per s&eacute; sia come adulteranti di partite di sostanze classiche, soprattutto eroina, causando scie di decessi per overdose.&nbsp;

Novel psychoactive substances (NPS) are synthetic substances belonging to diverse groups, designed to mimic the effects of scheduled drugs, resulting in altered toxicity and potency. Up to now, information available on the pharmacology and toxicology of these new substances is very limited, posing a considerable challenge for prevention and treatment. The present in vitro study investigated the possible mechanisms of toxicity of two emerging NPS (i) 4′-methyl-alpha-pyrrolidinoexanophenone (3,4-MDPHP), a synthetic cathinone, and (ii) 2-chloro-4,5-methylenedioxymethamphetamine (2-Cl-4,5-MDMA), a phenethylamine. In addition, to apply our model to the class of synthetic opioids, we evaluated the toxicity of fentanyl, as a reference compound for this group of frequently abused substances. To this aim, the in vitro toxic effects of these three compounds were evaluated in dopaminergic-differentiated SH-SY5Y cells. Following 24 h of exposure, all compounds induced a loss of viability, and oxidative stress in a concentration-dependent manner. 2-Cl-4,5-MDMA activates apoptotic processes, while 3,4-MDPHP elicits cell death by necrosis. Fentanyl triggers cell death through both mechanisms. Increased expression levels of pro-apoptotic Bax and caspase 3 activity were observed following 2-Cl-4,5-MDMA and fentanyl, but not 3,4-MDPHP exposure, confirming the different modes of cell death.
