Currently, increasing availability and popularity of designer benzodiazepines (DBZDs) constitutes a primary threat to public health. To assess this threat, the biological activity/potency of DBZDs was investigated using in silico studies. Specific Quantitative Structure Activity Relationship (QSAR) models were developed in Forge™ for the prediction of biological activity (IC 50 ) on the γ-aminobutyric acid A receptor (GABA-AR) of previously identified classified and unclassified DBDZs. A set of new potential ligands resulting from scaffold hopping studies conducted with MOE ® was also evaluated. Two generated QSAR models (i.e. 3D-field QSAR and RVM) returned very good performance statistics (r 2  = 0.98 [both] and q 2  = 0.75 and 0.72, respectively). The DBZDs predicted to be the most active were flubrotizolam, clonazolam, pynazolam and flucotizolam, consistently with what reported in literature and/or drug discussion fora. The scaffold hopping studies strongly suggest that replacement of the pendant phenyl moiety with a five-membered ring could increase biological activity and highlight the existence of a still unexplored chemical space for DBZDs. QSAR could be of use as a preliminary risk assessment model for (newly) identified DBZDs, as well as scaffold hopping for the creation of computational libraries that could be used by regulatory bodies as support tools for scheduling procedures., (© 2022 John Wiley & Sons Ltd.)

Background: Ketamine is a phencyclidine derivative with dissociative anaesthetic properties. Increasing numbers of individuals in England take ketamine recreationally. Information on deaths arising from such use in England is presented., Methods: Cases were extracted on 31 January 2020 from the National Programme on Substance Abuse Deaths database, based on text searches of the cause of death, coroner's verdict and positive toxicology results for the terms 'ketamine' or 'norketamine'., Findings: During 1997-2005, there were <5 deaths p.a. in which ketamine was implicated. Numbers increased until 2009 (21), plateauing until 2016; thereafter, deaths have risen to about 30 p.a. Decedents' characteristics ( N  = 283): male 84.1%, mean age 31.2 (SD 10.0) years, employed 56.5%, drug use history 79.6% and living with others 60.3%. Ketamine was detected with other substances in most cases. Main (74.6%) underlying cause of death was accidental poisoning. Ketamine may have impaired judgement in other cases., Conclusions: Although controlled, recreational ketamine use and related fatalities continue to increase. Consumers need to be more aware of the potentially fatal risks they face.

Psychedelics alter the perception of reality through agonist or partial agonist interaction with the 2A serotoninergic receptor. They are classified as phenethylamines, tryptamines and lysergamides. These classes, according to the United Nations Office on Drugs and Crime (UNODC) and European Monitoring Centre for Drugs and Drug Addiction (EMCDDA), account for an important percentage of the new psychoactive substances (NPS) current scenario.The paper aimed at: a) identifying and categorising psychedelic molecules from a list of psychonaut websites and NPS online resources; and b) comparing the NPSfinder Ⓡ results with those from the European and United Nations databases. A crawling software (i.e. 'NPSfinder Ⓡ ') was created to automatically scan, 24/7, a list of URLs and to extract a range of information (chemical/street names, chemical formulae, etc.) to facilitate NPS identification. Data collected were manually analysed and compared with the EMCDDA and UNODC databases.The overall number of psychedelic NPS detected by NPSfinder Ⓡ (November 2017-February 2020) was 1344, almost ten-times higher than that reported by the UNODC and EMCDDA combined. Of these, 994 previously unknown molecules were identified as (potential) novel psychedelics, suggesting a strong discrepancy between online and real-world NPS scenarios. The results show the interest of psychonauts, and maybe of the much larger community of 'recreational' drug users, towards psychedelics. Moreover, examining online scenario may help in assessing the availability in the real world of psychedelic NPS; understanding drug trends; and in possibly predicting future drug scenarios., Competing Interests: Conflict of interest All other authors declare that they have no conflicts of interest., (Copyright © 2021 Elsevier B.V. and ECNP.

The pursuit of pleasure among clubbers and disco-goers often involves drug use. However, whether substance use may represent a relevant risk factor contributing to the development of psychiatric symptoms and of mental illness remains debated. The purposes of this study were to evaluate the percentage of subjects who developed long-lasting psychiatric symptoms in a sample of subjects reporting use of substances in nightclubs, and to evaluate the role of a previous psychiatric diagnosis in these subjects. Data were collected during three consecutive years in dedicated nursing units inside all the nightclubs of Ibiza, in emergency hospital rooms at the Can Misses Hospital and inside the psychiatric ward. A total of 10,163 subjects required medical assistance inside discos in the medical-nursing units, of which 223 required transfers to hospital emergency rooms. Of these, 110 required subsequent psychiatric hospitalization. Ninety-one (82.7 %) of these patients had a positive psychiatric history, which was also found in thirty-one of the 113 subjects (27.4%) not requiring psychiatric hospitalization. Negative psychiatric history was negatively associated with hospitalization (Coefficient = -2.574; p = 0.000) and for subjects with a negative psychiatric history the odds to be hospitalized changed by a factor of 0.076. Gender, age, civil status and nationality were not significant predictors of hospitalization. Overall, the number of subjects who developed major psychiatric disorders appeared to be limited. However, the presence of a psychiatric history here played a crucial role. Club drugs are therefore able to induce psychiatric sequelae requiring hospitalization mainly in subjects who are already vulnerable from a psychopathological point of view.

Background and Objectives : Over the past twenty years a large number of new psychoactive substances (NPS) have entered and modified the recreational drug scene. Their intake has been associated with health-related risks, especially so for vulnerable populations such as people with severe mental illness, who might be at higher risk of suicidality or self-injurious behavior. This paper aims at providing an overview of NPS abuse and the effects on mental health and suicidality issues, by performing a literature review of the current related knowledge, thereby identifying those substances that, more than others, are linked to suicidal behaviors. Materials and Methods : A comprehensive and updated overview of the literature regarding suicidality and NPS categories has been undertaken. An electronic search was performed, including all papers published up to March 2021, using the following keywords "NPS" OR "new psychoactive substances" OR "novel psychoactive substances" OR "synthetic cannabinoids" OR "phenethylamines" OR "synthetic cathinones" OR "tryptamines" OR "piperazines" OR "new synthetic opioids" OR "designer benzodiazepines" AND ("suicide" OR "suicidality") NOT review NOT animal on the PubMed, Cochrane Library, and Web of Science online databases. Results : Suicidality and self-injurious behavior appear to be frequently associated with some NPS such as cathinones, synthetic cannabinoids, and new synthetic opioids. The results are organized according to the substances recorded. Conclusion : The growing use of NPS has become a significant clinical issue, causing increasing concern and challenges for clinicians working in both mental health and emergency departments. Thus, considering the associations between NPS and suicidality or self-injurious behaviors, areas where suicide-prevention efforts and strategies might be focused are the early detection, monitoring, and restriction of NPS.

Background: The present paper provides an updated review of both the large number of new/novel/emerging psychoactive substances (NPS) and their associated psychopathological consequences. Focus was here given on identification of those NPS being commented in specialised online sources and the related short-/long-term psychopathological and medical ill-health effects., Methods: NPS have been identified through an innovative crawling/navigating software, called the 'NPS.Finder®', created in order to facilitate the process of early recognition of NPS online. A range of information regarding NPS, including chemical and street names; chemical formula; three-dimensional image and anecdotally reported clinical/psychoactive effects, were here made available., Results: Using the 'NPS.Finder®' approach, a few thousand NPS were here preliminarily identified, a number which is about 4-fold higher than those figures suggested by European and international drug agencies. NPS most commonly associated with the onset of psychopathological consequences included here synthetic cannabinoids/cannabimimetics; new synthetic opioids; ketamine-like dissociatives; novel stimulants; novel psychedelics and several prescription and over-the-counter medicines., Conclusions: The ever-increasing changes in terms of recreational psychotropics' availability represent a relatively new challenge for psychiatry, as the pharmacodynamics and pharmacokinetics of many NPS have not been thoroughly understood. Health/mental health professionals should be informed about the range of NPS; their intake modalities; their psychoactive sought-after effects; the idiosyncratic psychotropics' combinations and finally, their medical and psychopathological risks.

Aims: Within the new psychoactive substances (NPS) scenario, several hundred different molecules, mostly including synthetic cannabinoids and cathinones, have been identified so far. The aims of the paper were to: (i) identify the number of synthetic cathinones mentioned in a range of psychonaut, NPS-related, online sources; and (ii) describe the associated acute/long term clinical scenario and the related treatment/management plan., Methods: After about 18 months of operation and exclusion of false positives/duplicates, some 4204 unique NPS molecules were included in the NPSfinder® crawling/navigating software database. Most popular NPS included: 1265 psychedelic phenethylamines (30.1%; confidence interval [CI] 95%: 28.7-31.5%); 1253 synthetic cannabinoids (29.8%; CI 95%: 28.4-31.2%); 429 synthetic opioids (10.2%; CI 95%: 9.3-10.2%); and 171 synthetic cathinones (4.1%; CI 95% 3.5-4.7%). Conversely, the United Nations Office on Drugs and Crime and the European Monitoring Centre for Drugs and Drug Addiction databases respectively included 169 and 140 cathinones. Overall, the 3 databases reported some 222 synthetic cathinones, and 41 were uniquely identified by the NPSfinder®., Results: In terms of clinical scenarios, synthetic cathinone ingestion is initially associated with stimulant effects; however, psychopathological disturbances, violence, suicidal behaviour, hyperthermia, coma and death have also been described., Conclusion: The proportion of cathinones commented on by psychonaut fora appeared to be relatively small, and similar to those reported by both the United Nations Office on Drugs and Crime and European Monitoring Centre for Drugs and Drug Addiction. This may be associated with a recent significant decline in both cathinone-related consumption and acute medical presentation. Due to their complex behavioural and medical toxicity issues, healthcare professionals should be, however, be educated to recognise the signs and symptoms of NPS, including synthetic cathinone, ingestion., (© 2019 The British Pharmacological Society.)

Novel psychoactive substances (NPS), especially those newly created, are largely an unknown quantity, particularly in terms of their potential serious adverse effects. This means that policy-makers and clinicians are under-informed about appropriate responses. Collation of detailed information on deaths related to NPS use can help in providing knowledge and understanding these aspects of the NPS phenomenon. The purpose of this review is to outline the role(s) which such evidence-based data can play in this respect. UK NPS-related cases demonstrate differences in definitions used by the General Mortality Registers, and differences between countries, not only in terms of the type of NPS implicated in deaths, but the number and extent of such deaths over time. NPS deaths are continuing to increase numerically and as a proportion of all drug-poisoning deaths. In order to better understand how specific molecules contribute to and/or cause death, detailed information collected by Special Mortality Registers can provide examples of substances' modes of action, adverse effects, symptomatology, treatment interventions, mechanisms of death, etc. This information can provide clinicians and policy-makers with objective information on the serious harms from such emerging molecules. Such evidence-based advice informs public health interventions, service provision and policy decisions on regulation and control of NPS. However, without reliable, accurate and complete information that is correctly collated, scientifically analysed and disseminated in a timely manner, an understanding of the phenomenon of what deaths can be ascribed to NPS, their characteristics and nature will remain unachieved, and thus limit what can be done to reduce them., (© 2019 The British Pharmacological Society.)

Aims: The risk of potential harms prompted the UK government to introduce the Psychoactive Substances Act in 2016. The aim of the present study was to evaluate the impact and effectiveness of this new legislation on patterns of novel psychoactive substance (NPS) awareness, use, experiences and risk awareness in a self-selected sample of UK consumers to inform education and policy., Methods: The Bristol Online Survey was advertised on the Bluelight drug forum and social media Facebook pages and University email between 7 January and 7 February 2015 (168 responses) and 9 March to 18 September 2017 (726 responses). UK country of residence responses were extracted for analysis (SPSS)., Results: In a predominantly university-educated, young (< 25 years) self-selecting sample, 1 year after introduction of the legislation, NPS use (in males, under 18s, those educated to school/college level, P < .001) has increased, whilst health risk awareness has not changed and remains poor. Users are switching to sourcing NPSs via street dealers (49%) and the darknet (31%) and showing an increase in preference for the herbal NPS Salvia divinorum (P < .05). The main reasons for NPS use remain the influence of friends (69%) in a social setting and to get high (76%) usually in combination with alcohol, cannabis or ecstasy., Conclusion: Regulation alone, so far, has not impacted on health risk awareness, NPS drug demand and culture in our UK survey sample. Alongside regulation, NPS health promotion education (particularly in schools, colleges) is needed that addresses resilience and both the risks and beneficial effects of NPS., (© 2019 The British Pharmacological Society.)

Drug checking services have been operating worldwide as a harm reduction tool in places like festivals and night clubs. A systematic review and netnographic analysis were conducted to explore the public's perception of drug checking. Although public perceptions of drug checking had not previously been evaluated in the literature, some positive and negative perceptions were captured. From twitter, a total of 1316 tweets were initially identified. Following the removal of irrelevant tweets, 235 relevant tweets were identified, of which about 95% (n = 223) tweets were in favour, and about 5% (n = 12) were not in favour of drug checking as a harm reduction intervention. Tweets perceived the service as part of effective law reform, public health intervention that serves in raising awareness and countering the role of the internet, initiative to reduce drug related harms and/ or potentially deaths, help in identifying Novel drug trends related to drugs, enabling a scientific basis to capture data, reducing harm from risky drugs or risky consumption, reducing the economic and social burden on society and preventing young people from having criminal records and punitive fines. Drug checking was perceived to support engagement with treatment services and support individuals in making more informed decisions. Tweets against drug checking focussed on the concerns over the quality of drug checking, particularly with false-positive results, which may lead to punitive outcomes, discrimination, and prejudice. The present study showed that twitter can be a useful platform to capture people's perceptions of drug checking., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Introduction: Over the past 10 years, a large number of New Psychoactive Substances (NPS) have entered the recreational drug scenario. NPS intake has been associated with health-related risks, and especially so for vulnerable populations such as the youngsters. Currently, most knowledge on the NPS health effects is learnt from both a range of users' reports, made available through the psychonauts' web fora, and from the few published, related toxicity, clinical observations. Areas covered: This paper aims at providing an overview of NPS effects on youngsters' mental health, whilst performing a systematic review of the current related knowledge. Expert opinion: NPS consumption poses serious health risks, due to both a range of unpredictable clinical pharmacological properties and the typical concomitant use of other psychoactive molecules; overall, this can lead to near misses and fatalities. In comparison with adults, the central nervous system of children/adolescents may be more vulnerable to the activity of these molecules, hence raising even further the levels of health-related concerns. More research is needed to provide evidence of both short- and long-term effects of NPS, related health risks, and their addiction potential.

Background: Misuse of gammahydroxybutrate (GHB) and its prodrugs gammabutyrolactone (GBL) and 1,4 butanediol (1,4-BD) has increased greatly since the early 1990s, particularly amongst lesbian, gay, bisexual and transgender (LGBT) individuals in recreational and sexual settings, e.g. 'chemsex'., Objective and Method: This paper presents an overview of GHB pharmacotoxicology and provides analyses of cases in the LGBT population associated with the use of these substances extracted from the UK's National Programme on Substance Abuse Deaths database, to which notification is voluntary., Results: From 1995 to September 2013, 21 GHB/GBL-associated fatalities were reported. None involved 1,4-BD. Typical victims were: Male (100%); White (67%), young (mean age 34 years); employed (90%); with a drug misuse history (81%). Most deaths were accidental (67%) or related to recreational drug use (19%), the remaining (potential) suicides. The majority of fatalities (83%) occurred in private residences, typically following recreational use; others occurred in specific 'gay'-oriented locales including clubs and saunas. Three London boroughs accounted for 62% of all notified deaths, reflecting the concentration of both resident and visiting 'gay' individuals. However, this may be an artefact of the voluntary nature of the data submission procedure in particular areas. GHB/GBL alone was implicated in 10% of fatalities. The following substances were implicated either alone or in combination in the remaining cases (percentages may add to more than 100%): cocaine (38%); alcohol (33%); amphetamines (29%); ecstasy (29%); diazepam (24%); ketamine (24%); mephedrone (24%). Post-mortem blood levels: mean 660 (range 22 - 2335; S.D. 726) mg/L., Conclusion: Significant caution is needed when ingesting GHB/GBL, particularly with alcohol, benzodiazepines, stimulants, and ketamine. Risk of death is increased due to their CNS-depressant properties. Of these, 'chemsex' drugs such as cocaine, mephedrone and ketamine are of note. More awareness is needed in the 'gay' community about risks associated with the consumption of such substances., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.org.)

Objective: Nowadays, the web is rapidly spreading, playing a significant role in the marketing or sale or distribution of "quasi" legal drugs, hence facilitating continuous changes in drug scenarios. The easily renewable and anarchic online drug-market is gradually transforming indeed the drug market itself, from a "street" to a "virtual" one, with customers being able to shop with a relative anonymity in a 24-hr marketplace. The hidden "deep web" is facilitating this phenomenon. The paper aims at providing an overview to mental health's and addiction's professionals on current knowledge about prodrug activities on the deep web., Methods: A nonparticipant netnographic qualitative study of a list of prodrug websites (blogs, fora, and drug marketplaces) located into the surface web was here carried out. A systematic Internet search was conducted on Duckduckgo® and Google® whilst including the following keywords: "drugs" or "legal highs" or "Novel Psychoactive Substances" or "NPS" combined with the word deep web., Results: Four themes (e.g., "How to access into the deepweb"; "Darknet and the online drug trading sites"; "Grams-search engine for the deep web"; and "Cryptocurrencies") and 14 categories were here generated and properly discussed., Conclusions: This paper represents a complete or systematical guideline about the deep web, specifically focusing on practical information on online drug marketplaces, useful for addiction's professionals., (Copyright © 2017 John Wiley & Sons, Ltd.)

Objectives: We aimed to describe a sample of subjects admitted to a psychiatric unit after the intake of psychoactive substances for recreational purposes., Methods: Between June and September 2015, 49 subjects were included. Sociodemographic characteristics and psychopathological aspects were investigated, and urine samples for further analysis were collected. Three subgroups (cannabinoids, stimulants, and depressors users) were identified, according to the structured interview regarding substance use and urinalysis., Results: Level of aggressiveness was found to be significantly higher (p < .05) in the cannabinoids subgroup. Self-reported symptom severity was comparable among groups, but trends could be identified: SCL-90 results showed a prevalence of anxiety symptoms among depressors users, hostility or aggression in the tetrahydrocannabinol subgroup, and psychoticism in the stimulants subgroup., Conclusions: The use of psychoactive substances was be characterised by poly-use of both traditional and novel substances. The presence of aggressiveness emerged as a main feature associated with the use of cannabis and other cannabinoids. Binge drinking and sleep deprivation also represented a relevant component in almost all the evaluated subjects., (Copyright © 2017 John Wiley & Sons, Ltd.)

Objectives and Methods: In the framework of the EU-funded project "EU-Madness," we collected and analysed all the reports of fatalities directly or indirectly related to substances of abuse registered in Ibiza from January to September 2015, in order to analyse the characteristics of the sample, the identified substances, and the nature of deaths associated with their consumption., Results: A significant increase of substance-caused deaths with respect to the previous 4 years has been highlighted. Most of the subjects were young males, more than half were not Spanish. Males prevailed also amongst the victims of traffic accidents and suicides. The most commonly involved substances included MDMA, alcohol, cocaine, THC, opiates and prescription drugs., Conclusions: Although the use of NPS is rapidly increasing in Europe, according to the results from our sample, alcohol and well-known stimulants (MDMA and cocaine) are still the substances of abuse mainly involved in the cases of substance-caused and substance-related fatalities. The significant increase of fatalities in Ibiza in the last 5 years is an issue that must be taken into account and should be better investigated, as other theories besides NPS-increased diffusion should be proposed, and therefore, targeted prevention strategies should be designed., (Copyright © 2017 John Wiley & Sons, Ltd.)

Introduction: Cathinones are one of the most popular categories of new psychoactive substances (NPS) consumed. Cathinones have different pharmacological activities and receptor selectivity for monoamine transporters based on their chemical structures. They are incorporated into NPS mixtures and used with other NPS or 'traditional' drugs. Cathinone use represents significant health risks to individuals and is a public health burden., Methods: Evidence of poly-NPS use with cathinones, seizure information, and literature analyses results on NPS mixtures was systematically gathered from online database sources, including Google Scholar, Scopus, Bluelight, and Drugs-Forum., Results and Discussion: Results highlight the prevalence of NPS with low purity, incorporation of cathinones into NPS mixtures since 2008, and multiple members of the cathinone family being present in individual UK-seized samples. Cathinones were identified as adulterants in NPS marketed as being pure NPS, drugs of abuse, branded products, herbal blends, and products labelled "not for human consumption." Toxicity resulting from cathinone mixtures is unpredictable because key attributes remain largely unknown. Symptoms of intoxication include neuro-psychological, psychiatric, and metabolic symptoms. Proposed treatment includes holistic approaches involving psychosocial, psychiatric and pharmacological interventions., Conclusion: Raising awareness of NPS, education, and training of health care professionals are paramount in reducing harms related to cathinone use., (Copyright © 2017 John Wiley & Sons, Ltd.)

A range of information needs should be met in order to better understand and predict the longevity/existence of novel psychoactive substances (NPS). This conceptual paper argues that one way of assessing how long a molecule may be around is to document how the life cycles or natural histories of 'traditional' drugs and NPS evolve. The earliest indication of the possible appearance of a new substance might be evidenced on the DeepWeb. However, this means they are less visible, in line with the clandestine nature of drug use and supply. Therefore, monitoring discussion groups/fora needs the development of new methods compared to those used in the Surface Net. Issues needing consideration in establishing NPS life cycles are outlined here, together with the probable outcomes that could result. The approach advocated means that it should be easier to identify which NPS are likely to come up or are emerging in real time, and, therefore, pre-empt/prevent their supply., (Copyright © 2017 John Wiley & Sons, Ltd.)

Background: 4,4'-DMAR (4,4'-dimethylaminorex; "Serotoni") is a potent stimulant drug that has recently been associated with a number of fatalities in Europe. Over the last few years, online communities have emerged as important resources for disseminating levels of technical knowledge on novel psychoactive substances., Objective: Analysing the information provided by the fora communities on 4,4'-DMAR use, additionally critical reviewing the available evidence-based literature on this topic., Methods: Different website drug fora were identified. A critical review of the existing evidence-based literature was undertaken. Individuation and analysis of qualitative data from the identified website fora were performed., Results: The combined search results identified six website fora from which a range of qualitative data on recurring themes was collected. These themes included routes of administration and doses; desired effects; adverse effects; comparison with other drugs; association with other drugs; medications self-administered to reverse 4,4'-DMAR action; overall impression; and provision of harm-reduction advice., Conclusions: Although being characterized by a number of methodological limitations, the social networks' Web monitoring approach (netnography) may be helpful to better understand some of the clinical and psychopharmacological issues pertaining to a range of novel psychoactive substances, including 4,4'-DMAR, for which only extremely little, if any, scientific knowledge is available., (Copyright © 2017 John Wiley & Sons, Ltd.)

Over the last decade there has been an explosion of new drugs of abuse, so called legal highs or novel psychoactive substances (NPS). Many of these abused drugs have unknown pharmacology, but their biological effects can be anticipated from their molecular structure and possibly also from online user reports. When considered with the findings that some prescription medications are increasingly abused and that some abused drugs have been tested clinically one could argue that there has been a blurring of the line between drugs of abuse and clinically used drugs. In this review we examine these legal highs/NPS and consider whether, based on their known or predicted pharmacology, some might have the potential to be clinically useful in CNS disorders., (Copyright © 2015 Elsevier Inc.

Objective: Mephedrone is a stimulant drug chemically related to amphetamine, with effects similar to those of amphetamine and cocaine. This study aims to analyse fatalities following ingestion of mephedrone in the UK amongst 16- to 24-year-olds in 2009-2013, providing an update on data presented at the 2nd International Conference on Novel Psychoactive Substances., Methods: A literature search was undertaken to identify published information on pharmacology, toxicity and fatalities associated with mephedrone. Fatalities involving mephedrone were extracted from the National Programme on Substance Abuse Deaths database, which receives information on drug-related deaths from coroners in the UK and Islands and other data suppliers. Selection criteria are as follows: deceased aged 16-24 years at time of death and mephedrone directly implicated in the cause of death and/or mentioned in the coroner's verdict., Results: Thirty cases met the study criteria, and when known, all were of White ethnicity, most (85%) had a history of drug use and 73% were male. Two-thirds (63%) were accidental poisonings. Mephedrone was used with other substances in most cases (87%); other substances were implicated in 60% of deaths., Conclusions: Mephedrone use can have potentially fatal consequences, especially in combination with other substances. Deaths from its use in the 16-24 years' age group continue to occur in the UK, despite it being a controlled drug. Health professionals and potential consumers should be alert to this risk., (Copyright © 2015 John Wiley & Sons, Ltd.)

Objective: The goal of this study is to provide an update on the data given on methoxetamine (MXE)-related fatalities that occurred in 2011-2013, presented at the Second International Conference on Novel Psychoactive Substances., Methods: Fatalities involving MXE were extracted from the database of the National Programme on Substance Abuse Deaths, which receives information on drug-related deaths from Coroners in the UK and Islands (Isle of Man, Jersey, Guernsey) and other data suppliers., Results: Eight cases, received by 3 September 2013, in which MXE was found at post-mortem and/or directly implicated in the death and/or mentioned in the Coroner's verdict are described. The median age at death was 27 years, with the majority of White ethnicity (6/8) and male (7/8). MXE was used together with other substances in 7/8 cases. MXE was found at post-mortem in all cases, directly implicated in the deaths of four and likely to have had an influence in two., Conclusions: More research needs to be conducted into its health effects and toxicity potential. Health care professionals should be made aware of the potential health harms of MXE, in order to develop early intervention measures and minimise the number of MXE-related poisonings and fatalities., (Copyright © 2015 John Wiley & Sons, Ltd.)

Objectives: Internet and social networking sites play a significant role in the marketing and distribution of recreational/prescription drugs without restrictions. We aimed here at reviewing data relating to the profile of the online drug customer and at describing drug vending websites., Methods: The PubMed, Google Scholar, and Scopus databases were searched here in order to elicit data on the socio-demographic characteristics of the recreational marketplaces/online pharmacies' customers and the determinants relating to online drug purchasing activities., Results: Typical online recreational drugs' customers seem to be Caucasian, men, in their 20s, highly educated, and using the web to impact as minimally as possible on their existing work/professional status. Conversely, people without any health insurance seemed to look at the web as a source of more affordable prescription medicines. Drug vending websites are typically presented here with a "no prescription required" approach, together with aggressive marketing strategies., Conclusions: The online availability of recreational/prescriptions drugs remains a public health concern. A more precise understanding of online vending sites' customers may well facilitate the drafting and implementation of proper prevention campaigns aimed at counteracting the increasing levels of online drug acquisition and hence intake activities., (Copyright © 2015 John Wiley & Sons, Ltd.)

Within online drug fora communities, there are some "educated and informed" users who can somehow provide reliable information on psychoactive compounds and combinations. These users, also called "e-psychonauts," may possess levels of technical knowledge relating to a range of novel psychoactive substances (NPS). The present project aimed at identifying and describing the e-psychonauts' socio-demographic characteristics and their motivations and patterns of drug intake. A netnographic research methodology, carried out through an unobtrusive observational approach of a list of cyber drug communities (blogs, fora, Facebook, and Twitter pages) was carried out. The fora posts and threads were accurately reviewed, analyzed, and compared using the empirical phenomenological psychological (EPP) method. Data were collected between January and February 2014. Psychonauts typically considered themselves as "psychedelic researchers," "new Shamans," "philosophers," or "alchemists." They appeared to be mainly young, males, unmarried, and Caucasians. They presented with good or excellent employment conditions and with a set of key skills, including attention to their inner "soul"; high standards of knowledge about drugs' chemical and pharmacological issues; and high levels of both IT skills and verbal fluency in reporting their own "on drug" experiences. The e-psychonauts seemed to "test" and at times synthesize a range of drugs to achieve the state of consciousness they find most pleasurable. There is the need to improve both the existing levels of professionals' knowledge on this novel generation of drug misusers and to design and develop novel prevention approaches that are able to attract the attention of the e-psychonauts.

Introduction: Performance and image-enhancing drugs (PIEDs), also known as "lifestyle drugs," are increasingly sold on the Internet to enhance cognitive as well as sexual, muscular, attentive, and other natural capacities. Our analysis focuses on the misuse of the cognitive enhancer piracetam., Methods: A literature review was carried out in PsychInfo and Pubmed database. Considering the absence of peer-reviewed data, review of additional sources of unstructured information from the Internet was carried out between February 2012 and July 2013. Additional searches were conducted using the Global Public Health Intelligence Network (GPHIN), a secure Internet-based early warning system developed by Health Canada and the World Health Organization (WHO), which monitors media reports in six languages, Arabic, Chinese, English, French, Russian, and Spanish., Results: Piracetam is sold via illicit online pharmacies with no need of prescription at low prices. Buyers, mainly healthy individuals, purchase the product to enhance study- and work-related performances as well as for recreational purposes. Its nonmedical use is often associated with the occurrence of side effects such as hallucinations, psychomotor agitation, dysphoria, tiredness, dizziness, memory loss, headache, and severe diarrhoea; moreover, several users declared to have neither felt any cognitive improvement nor psychedelic effects., Conclusions: This is a new and fast-growing trend of abuse that needs to be extensively monitored and studied also by using near real-time and unstructured sources of information such as Internet news and online reports in order to acquire rapid knowledge and understanding. Products sold online might be counterfeits and this enhances related health risks.

Unlabelled: Abstract Introduction: Novel Psychoactive Substances (NPSs) are often sold online as "legal" and "safer" alternatives to International Controlled Drugs (ICDs) with captivating marketing strategies. Our aim was to review and summarize such strategies in terms of the appearance of the products, the brand names, and the latest trends in the illicit online marketplaces., Methods: Scientific data were searched in PsychInfo and Pubmed databases; results were integrated with an extensive monitoring of Internet (websites, online shops, chat rooms, fora, social networks) and media sources in nine languages (English, French, Farsi, Portuguese, Arabic, Russian, Spanish, and Chinese simplified/traditional) available from secure databases of the Global Public Health Intelligence Network., Results: Evolving strategies for the online diffusion and the retail of NPSs have been identified, including discounts and periodic offers on chosen products. Advertisements and new brand names have been designed to attract customers, especially young people. An increased number of retailers have been recorded as well as new Web platforms and privacy systems., Discussion: NPSs represent an unprecedented challenge in the field of public health with social, cultural, legal, and political implications. Web monitoring activities are essential for mapping the diffusion of NPSs and for supporting innovative Web-based prevention programmes.

Purpose of Review: New psychoactive substances refer to emerging substances that have appeared on the market and are not under international control. NPS have been categorized in different main groups (e.g. synthetic cannabinoids, synthetic cathinones, phenethylamines, piperazines, ketamine and phencyclidine-type substances, tryptamines). This article reviews the recent literature regarding emerging trends of NPS in Europe., Recent Findings: According to the last report of the European Union Early warning system (EWS), 73 NPS were officially identified for the first time. The more frequent NPS self-reported or detected are synthetic cannabinoids and cathinones. A combination of different NPS and also mixed with other drugs, mainly cannabis and ecstasy, is usual among experienced drug users. Acute NPS toxicity includes significant psychoactive and sympathomimetic effects., Summary: This article summarizes new European epidemiological and clinical data published between January and December 2013 on NPS. In the last few years, there has been a rapid increase in the number of NPS launched on the European drugs market. The presence of some of these new substances has been detected through surveys/questionnaires, studies in drug samples and biological fluids, and case reports and NPS-induced fatalities.

Background: The recent emergence of new recreational drugs, combined with the ability of the Internet to disseminate information quickly, have raised a number of concerns in the fields of drug policy, substance use research, and public health., Methods: A semi-structured questionnaire was advertised on The Study Room's website from November to December 2010 to explore the awareness, the use and the perception of risks of "legal highs" among student population in the UK., Results: One-third (31.40%) of the 446 participants reported use of these kinds of drugs. Respondents were more likely to have taken were: mephedrone (41.4%), Salvia divinorum (20%), "Spice drugs" (10.7%), methylone (1.4%), naphyrone (NRG) (2.1%) and benzylpiperazine (BZP) (2.1%), while 15.7% did not know what compounds they had ever consumed. The large majority (78.9%) considered these as legal substances, while 74.2% did not consider these safer than illicit drugs. Half (50.8%) of the respondents were aware of the presence of illegal agents in the products they had consumed., Conclusions: The study contributes to an initial assessment of the use and the risks awareness of novel psychoactive compounds among students in the UK. Further research is required, especially in terms of personality and lifestyle attitudes to better profile these new forms of abuse also in non-recreational settings.

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.

Background: Tropicamide is an antimuscarinic drug usually prescribed as an ophthalmic solution to induce short-term mydriasis and cycloplegia. Over the last 2 years, tropicamide has been reported in both Russia and Italy to be self-administered intravenously (IV) for recreational purposes., Methods: The literature on tropicamide was searched in PsycInfo and Pubmed databases. Considering the absence of peer-reviewed data, results were integrated with a multilingual qualitative assessment of a range of Web sites, drug fora and other online resources (i.e., e-newsgroups, chat rooms, mailing lists, e-newsletters and bulletin boards): between January 2012 and January 2013, exploratory qualitative searches of more than 100 Web sites have been carried out in English and Italian using generic and specific keywords such as "legal highs," "research chemicals," "online pharmacy," "tropicamide," "mydriacil," "tropicacyl," "visumidriatic," "online pharmacies" and "tropicamide recreational abuse" in the Google search engine., Results: Misuse of tropicamide typically occurs through IV injection; its effects last from 30 min to 6 h, and it is often taken in combination with other psychoactive compounds, most typically alcohol, marijuana and opiates. Medical effects of tropicamide misuse include slurred speech, persistent mydriasis, unconsciousness/unresponsiveness, hallucinations, kidney pain, dysphoria, "open eye dreams," hyperthermia, tremors, suicidal feelings, convulsions, psychomotor agitation, tachycardia and headache., Discussion/conclusions: More large-scale studies need to be carried out to confirm and better describe the extent of tropicamide misuse in the European Union and elsewhere. Health and other professionals should be rapidly informed about this new and alerting trend of misuse., (Copyright © 2013 Elsevier Inc. All rights reserved.)

In this article, ontogenetic and phylogenetic causes of drug abuse and links to human emotional development are considered. Some evolutionary perspectives (e.g. that under certain conditions, consumption of otherwise toxic alkaloids may confer both physical and cultural advantages) are reviewed. As described in the 'mismatch theory', the capacity of the human genome to evolve defences against toxins has been outstripped by the pace of cultural change and technological development, such as purposeful fermentation of alcohol and more recently distillation of alcohol; purification and chemical manipulation of plant alkaloids; and the engineering of entirely novel psychoactive substances (NPS). The functions of the neurobiological substrates that mediate substance misuse and dependence are reviewed. Reasons are given why NPSs present greater cause for concern than plant-derived substances of abuse. We argue that evolutionary biology provides an important orientation for the research agenda in substance misuse., (Copyright © 2013 John Wiley & Sons, Ltd.)

Objectives: MDAI (5,6-methylenedioxy-2-aminoindane; 6,7-dihydro-5H-cyclopenta[f][1,3]benzodioxol-6-amine; 'sparkle'; 'mindy') is a psychoactive substance, sold primarily over the Internet and in 'head' shops as a 'legal high'. Synthesised and used as a research chemical in the 1990s, MDAI has structural similarities to MDMA (3,4-methylenedioxy-N-methylamphetamine) and shares its behavioural properties. Recreational use of MDAI appears to have started in Europe around 2007, with a noticeable increase after 2009 in the UK and other countries. Calls to National Poisons Information Services started in 2010, although there were few presentations to emergency departments by patients complaining of undesirable physical and psychiatric effects after taking MDAI. Recreational use of this drug has been reported only occasionally by online user fora. There is little scientifically based literature on the pharmacological, physiological, psychopharmacological, toxicological and epidemiological characteristics of this drug., Methods: Recent literature (including 'grey') was searched to update what is known about MDAI, especially on its toxicity., Results: The resultant information is presented, including on the first three UK deaths involving MDAI use in 2011 and 2012. 'Serotonin syndrome' appears to be a possible factor in these fatalities., Conclusion: It is vital that any other cases, including non-fatal overdoses, are documented so that a scientific evidence base can be established for them., (Copyright © 2013 John Wiley & Sons, Ltd.)

Objectives: The use of synthetic cannabimimetics (SC; "spice" drugs) is increasing, especially among teenagers and young adults. In parallel with this, the number of studies describing intoxication episodes associated with psychotic symptoms in SC users is growing. We present both a systematic review of the related literature and a case report, which seems to highlight the existence of a possible association between SC use and psychosis., Methods: Some 223 relevant studies were here identified and reviewed. Out of these, 120 full text articles were assessed for eligibility, and 41 were finally included in the systematic review., Results: According to the available data from the studies here identified, SC's average age of users was 22.97 years, and the male/female ratio was 3.16:1. SC compounds most often reported in studies using biological specimen analysis were JWH-018, JWH-073, JWH-122, CP-47,497, and JWH-250. Mounting evidence seemed to suggest that psychotic symptoms such as hallucinations and delusions may occur in acute/chronic SC users., Conclusions: Although a clear causal link may not be here identified, the available evidence suggests that SC can trigger the onset of acute psychosis in vulnerable individuals and/or the exacerbation of psychotic episodes in those with a previous psychiatric history., (Copyright © 2013 John Wiley & Sons, Ltd.)

Objective: This study aimed to review the available evidence-based literature on novel psychoactive substances and to inform health care professionals., Methods: Internet searches were carried out using Google and Yahoo by using specific key words. For each set of key words, the first 100 websites identified by Google and Yahoo were fully assessed, together with a further 5% of random samples selected by research randomizer of the remaining websites. Thus, a list of unique web forums was identified, and qualitative information was extracted. Available evidence-based literature were reviewed along with a user's experimentation with mephedrone, NRG-1, NRG-2 and Benzofury., Results: It showed that when a substance (mephedrone) became controlled, the vendors aggressively promote the sale of other new compounds (NRG-1, NRG-2, Benzofury) to attract vulnerable adults. The characteristics, toxicity and suggested management of these new compounds (NRG-1, NRG-2, Benzofury) are discussed., Conclusions: The arrival of hundreds of novel psychoactive substances for sale online has raised a number of public health and legal issues. Although evidence-based literature remains limited, few studies identified that most products do not contain the ingredients as advertised. Better levels of international cooperation and rapid share of available information may be needed to tackle this emerging problem., (Copyright © 2013 John Wiley & Sons, Ltd.)

This article reviews the recreational use of ketamine ("Special K"; KET) and explores the recent diffusion of its new derivative methoxetamine ("Special M"; MXE). The literature search on the nonclinical/recreational use of KET and MXE was carried out in a range of medical databases. Considering the limitations of peer-reviewed information, data were integrated with a qualitative assessment of a range of websites, drug fora, and other online resources including e-newsgroups, chat rooms, mailing lists, e-newsletters, and bulletin boards. The recreational use of KET has started since its discovery in 1962. This was due to its rapid onset, short duration of action, and peculiar psychotropic effects ("K-hole"). The latter effect ranges from confusion to dissociation and depersonalization (near-death experience). However, KET abuse is often associated with physical and psychological side effects, of which the worst is urological/bladder toxicity. Recently, MXE has emerged as a legal and "bladder-friendly" KET alternative. MXE presents with the same dissociative effect of KET, but with slower onset and longer duration of action. However, MXE seems to be associated with worse side effects than KET, ranging from mood disturbances/suicidal attempts to acute cerebellar toxicity. After 50 years of its discovery, KET has led to the emergence of MXE. However, this latter derivative does not appear to be a safer alternative to KET itself., (© 2013 John Wiley & Sons Ltd.)

Background: This paper presents the outcomes of the 2-year European Union funded Psychonaut Web Mapping Project which aimed at developing and implementing an integrated web mapping system to promptly identify and learn about novel psychoactive substances (NPS; "legal highs") through the regular monitoring of the Internet., Methods: More than 200 discussion forums, social media, online shops, websites and other Internet resources (e.g. YouTube, eBay, Google, Google Insight) have been extensively and regularly monitored in 7 European countries (UK, Finland, Norway, Belgium, Germany, Italy and Spain) for emerging trends of NPS throughout the period of the study., Results: Key online resources have been identified as "leading edge" which have provided accurate and timely information on novel emerging compounds. In total more than 400 substances/products have been recorded. NPS have been noted online before reaching wider audiences., Discussion: Although a high number of novel psychoactive substances have been identified in the 2-year duration of the project, not all have become trends that needed public health response. Conversely, new recreational drug phenomena such as "spice drugs," mephedrone and naphyrone were all identified as emerging trends in forums and websites. In addition, it has been possible for the first time to collate detailed information on these and several more compounds even though no or limited scientific publications were available. It is therefore recommended that these monitoring activities are to be continued, that more countries, researchers and health professionals are involved, and that the findings are widely shared with all the relevant agencies, health professionals and future research projects. Implications, advantages and limitations of using the Internet as primary source for identifying emerging trends are also discussed., (Copyright © 2012 Elsevier Inc. All rights reserved.)

5-MeO-DALT (N,N-diallyl-5-methoxytryptamine) is a psychoactive substance, sold primarily over the Internet as a 'research chemical' or 'plant food'. Although details for the synthesis of this tryptamine have been available since 2004, its use as a hallucinogenic drug has been reported only occasionally in on-line user fora. It is controlled in only a few countries world-wide. There is little scientifically-based literature on the pharmacological, physiological, psychopharmacological, toxicological and epidemiological characteristics of 5-MeO-DALT. Here we review what is known about these aspects. We also report what we believe to be the first death involving the use of this substance. The case involved a man in his mid-20s who died in mid-2010. The coroner concluded that the deceased "died from injuries sustained after being hit by a lorry whilst under the influence of 5-MeODALT". It is critical that any other cases, including non-fatal instances, are documented so that a scientific evidence-base can be established for this drug., (Copyright © 2012 Elsevier Inc.

2-DPMP (desoxypipradrol, 2-benzhydrylpiperidine, 2-phenylmethylpiperidine) and D2PM (diphenyl-2-pyrrolidin-2-yl-methanol, diphenylprolinol) are psychoactive substances, sold primarily over the Internet and in 'head' shops as 'legal highs', 'research chemicals' or 'plant food'. Originally developed in the 1950s for the treatment of narcolepsy and ADHD, 2-DPMP's use soon became very limited. Recreational use of 2-DPMP and D2PM appears to have started in March 2007, but only developed slowly. However, in the UK their popularity grew in 2009, increasing rapidly during summer 2010. At this time, there were many presentations to UK Emergency Departments by patients complaining of undesirable physical and psychiatric effects after taking 2-DPMP. In spring 2011 there were similar presentations for D2PM. Recreational use of these drugs has been reported only occasionally in on-line user fora. There is little scientifically-based literature on the pharmacological, physiological, psychopharmacological, toxicological and epidemiological characteristics of these drugs. Here we describe what is known about them, especially on their toxicity, including what we believe to be the first three deaths involving the use of 2-DPMP in August 2010. There are no international controls imposed on 2-DPMP or D2PM. However, a ban on their UK importation was imposed in November 2011 and they became Class C drugs on 13 June 2012. It is critical that any other cases, including non-fatal overdoses, are documented so that a scientific evidence-base can be established for them., (Copyright © 2012 Elsevier Inc.

Background: International media have been reporting about fatalities allegedly related to mephedrone, a popular recreational stimulant, but now a proportion of them have been confirmed. We aimed here at analyzing information relating to the circumstances of mephedrone-related deaths in the United Kingdom., Methods: Descriptive analysis of information was mainly extracted from the UK National Programme on Substance Abuse Deaths database. With an average annual response rate of 95%, UK National Programme on Substance Abuse Deaths receives information from coroners on drug-related deaths among both addicts and nonaddicts in the United Kingdom, the Channel Islands, and the Isle of Man., Results: So far, 128 alleged mephedrone-associated fatalities have been reported; mephedrone was identified at postmortem in 90 cases; inquests have been concluded in 69 cases, 62 of which are analyzed here. Typical mephedrone victims were young (mean age, 28.8 years), male, and with a previous history of drug misuse. There was a notable number (18 cases [29%], 11 being from hanging) of deaths involving self-harm. Mephedrone alone was identified at postmortem on 8 occasions (13% of the inquests' sample)., Conclusions: Present mortality data may suggest a significant level of caution when ingesting mephedrone. Limitations include an inability to determine the exact extent of risks associated with mephedrone consumption.

Background: "Legal highs" are becoming increasingly common features of the recreational drug market. The Internet has emerged as an important resource for technical and pharmacological knowledge in the absence of evidence-based literature, and for identifying emerging trends. Self-established drug-related Internet forums have emerged as particularly useful sources of information., Aims: It was the aim of this study to explore the key features of drug-related Internet forums and the drug forum communities., Methods: Within the framework of the larger Psychonaut Web Mapping project, eight English-language drug forums were assessed, and key features, categories, themes and attributions were identified., Results: The results are reported taking into account ethical issues, such as anonymity and confidentiality, associated with research in online communities., Conclusions: This study identified strong, unified and unique communities of recreational drug users that can provide an insight into the growing market in new drugs and drug compounds, and may be key components in future research, harm reduction and prevention strategies.

On the basis of the material available both in the scientific literature and on the web, this paper aims to provide a pharmacological, chemical and behavioural overview of the novel compound methoxetamine. This is a dissociative drug related to ketamine, with a much longer duration of action and intensity of effects. A critical discussion of the availability of information on the web of methoxetamine as a new recreational trend is here provided. Those methodological limitations, which are intrinsically associated with the analysis of online, non-peer reviewed, material, are here discussed as well. It is concluded that the online availability of information on novel psychoactive drugs, such as methoxethanine, may constitute a pressing public health challenge. Better international collaboration levels and novel forms of intervention are necessary to tackle this fast-growing phenomenon., (Copyright © 2012 John Wiley & Sons, Ltd.)

Based on the material available in both the scientific literature and on the web, the present paper provides an updated pharmacological, chemical, toxicological and behavioural overview of Bromo-Dragonfly (1-(8-bromobenzo[1,2-b;4,5-b']difuran-4-yl)-2-aminopropane; 'B-fly'). B-Fly is a powerful, long lasting, LSD-like, hallucinogenic drug, which has been associated with a number of acute intoxications and fatalities in a number of countries. A critical discussion of the potential of misuse of B-fly but also of the methodological limitations, which are intrinsically associated with the analysis of online, non-peer reviewed, material, is presented. It is concluded that the availability of online information on novel psychoactive drugs, such as B-fly, may constitute a public health challenge. Better international collaboration levels may be needed to tackle this novel and fast growing phenomenon.

In the last decade, a global trend of escalating ecstasy (MDMA, MDA, MDEA, MBDB) use was observed. Mentions on medical death certificates, last year's ecstasy use, number of drug offenders, seizures, prices and dosage levels figures were used for this descriptive and correlational study. Figures (1994-2003) were taken from the UK General Mortality Registers, from the Home Office Statistical Bulletins, from the British Crime Survey and from those reported to both the National Crime Intelligence and Forensic Science Services. A total of 394 ecstasy deaths mentions were here identified from the UK; in 42% of cases ecstasy was the sole drug mentioned. Overall, number of fatalities showed a year-per-year increase and positively correlated with: prevalence of last year's use (p < 0.01); number of offenders (p < 0.01) and number of seizures (p < 0.01) but negatively correlated with ecstasy price (p < 0.05). Price negatively correlated with: prevalence of last year's use (p < 0.001) and number of seizures (p < 0.01); but positively correlated with average MDMA dosage per tablet (p < 0.01). MDA, MDEA and MBDB accounted for a significant proportion of tablets only up to 1997, but not afterwards. Increasing production with a concomitant decrease in ecstasy price may have facilitated an increase in consumption levels and this, in turn, may have determined an increase in number of ecstasy deaths mentions. Only medical death certificates and not coroners' reports at the end of their inquests were here analysed; no data were available in respect of other drugs use and toxicology results.

2C-T-7 ('Blue Mystic'), an illicit compound which shows similarities with MDMA and other designer drugs, has been only occasionally identified in the EU, but discussion on the Internet between experimenters has recently grown significantly. We aimed at collecting together in a review the available information on 2C-T-7, both at the cyber and at the street market level. 2C-T-7 was first synthesized in 1986; its desired effects include both a sense of empathy and of well-being. Hallucinations, nausea, anxiety, panic attacks and paranoid ideation are anecdotally reported. According to the different European sources here approached, the availability of 2C-T-7 at street level seems to be currently very low, although one death related to a mono-intoxication with 2C-T-7 has been documented in the USA. With respect to information on 2C-T-7 available online, due to both redundancy and relevance issues the initial identified sample of 360 was reduced to 118 websites. In 14 (11.9%) websites, the detailed description of the 2C-T-7 synthesis was given. Harm Reduction websites appeared significantly earlier in the search engines results' list than Anti drugs (p 0.006) websites. Five (4.2%) websites apparently offered 2C-T-7 for sale. The large body of knowledge available online seems to contrast with small numbers of seizures at street level; an exhaustive web mapping of drug-related issues may be of interest for the clinician. Projects aimed at designing more 'attractive' prevention websites should be planned and future studies should better assess the characteristics of those consumers who take advantage of the online information of hallucinogenic compounds.

What do therapy and cybertherapy need to take into account to be effective for the treatment of drug-related disorders? The Psychonaut 2002 project is aimed to create a new and updated Web-based tool, which will be based on evolving drug scenarios, in order to provide professionals from the drug addiction field with easily accessible and reliable information. The drug abuse settings available on the Web will be described and the methodology will be discussed. Preliminary results of a search on MDMA and MDMA-like substances confirm that it is possible both to identify emerging trends and to provide information for prevention and appropriate intervention.
