Over the last decade, the “traditional” drug scene has been supplemented – but not replaced – by the emergence of a range of novel psychoactive substances (NPS), which are either newly created or existing drugs, including medications, now being used in novel ways. By the end of 2015, in excess of 700 NPS had been reported by a large number of countries in the world. Most recent data show however that synthetic cathinones; synthetic cannabinoids; and psychedelics/phenethylamines; account for the largest number of NPS. Given the vast range of medical and psychopathological issues associated with the molecules here described, it is crucial for health professionals to be aware of the effects and toxicity of NPS. The “Drugs 2.0.” revolution facilitated the birth and growth of an “Online Drug Culture” which finds its main expression in chats/fora/blogs as well as the diffusion of online drug marketplaces (both in the surface and deep web). The web has progressively modified the drug market from a “street” into a “virtual” one, so by increasing the availability of new drugs/NPS/“legal highs” (“legal alternatives” to the traditional illegal drugs). The rapid pace of change in the NPS online market constitutes a major challenge to the provision of current and reliable scientific knowledge on these substances. The present lecture aims at providing an overview of the NPS phenomenon, also giving an overview of the main clinical and pharmacological issues relating to these most popular NPS categories.Disclosure of interestThe authors have not supplied their declaration of competing interest.

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.

Background: ‘Legal highs’ began appearing in the UK in the mid-2000s. Whilst many of these substances were controlled under the 1971 Misuse of Drugs Act, novel compounds and new variants of controlled compounds were continuously being introduced to the recreational drug market. The Psychoactive Substances Act (PSA) was therefore implemented in 2016 as a blanket ban on all novel psychoactive substances (NPS). Aim: To evaluate the impact of the PSA on deaths following NPS use in England, Wales and Northern Ireland. Methods: Cases reported to the National Programme on Substance Abuse Deaths where death had occurred 3 years pre- or post-implementation of the PSA were extracted. Cases with NPS detected at post-mortem were analysed and compared against cases non-NPS cases. Results: 293 deaths with NPS detected were identified; 91 occurring before the PSA and 202 afterwards, indicating an 222.0% post-PSA increase. Contrastingly, non-NPS drug-related death case reporting increased by only 8.0%. Synthetic cannabinoid, anxiolytic/sedative and stimulant NPS were detected in the largest proportions of deaths pre-PSA; post-PSA stimulant NPS detections reduced whilst synthetic cannabinoid and anxiolytic/sedative detections increased. Post-PSA, average decedent age increased significantly (mean age pre-PSA 34.4 ± 10.8 vs post-PSA 38.3 ± 9.4), and they were significantly more likely to have been living in deprived areas (pre-PSA 50.0% vs post-PSA 65.9%). Conclusions: Reporting of deaths following NPS use has risen despite introduction of the PSA. Whilst deaths amongst younger individuals and those living in more affluent areas has reduced, additional approaches to prohibition are needed to curb their persistence in deprived demographics.

Questo articolo nasce dall'esigenza di informare un più ampio pubblico sul pericolo rappresentato da queste sostanze, far conoscere le NPS (Novel Psychoactive substances) agli operatori del settore (personale di laboratorio, personale delle unità 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. 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 sé sia come adulteranti di partite di sostanze classiche, soprattutto eroina, causando scie di decessi per overdose.

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.

In this paper the authors summarize experience of a drug service provider with the injecting use of novel psychoactive substances. Among clients of the needle exchange programme of Blue Point Drug Counselling and Outpatient Centre, the authors observed the spread of the novel substances since 2009. The extensive spread of the novel substances caused substantial change in injecting use patterns, thus in the usage of the needle exchange programme. The novel psychoactive substances appeared consecutively, so that this setting gave a unique opportunity to observe and track the emergence of these substances. The authors summarize the characteristics which are important for medical practice (risks, frequent use, severe psychopathological conditions) as well as special risks associated with these substances (substances with unknown composition and effect). They highlight the importance and role of the early warning system, monitoring the online sources of information and testing of samples containing novel psychoactive substances. Orv.
