Kronic hysteria: Exploring the intersection between Australian synthetic cannabis legislation, the media, and drug-related harm

Predicting the Number of GHB-Related Toxicologic Admissions Using Google Trends Data

In the era of novel psychoactive substances (NPS), the internet became a relevant source of information and purchase for those who consume psychoactive drugs. Parallelly, a growing body of research aim to utilize web search metrics (most commonly by relying on Google Trends data) in the prediction of substance use-related trends, including epidemiological forecasting. The main goal of the current study was to assess the utility of web search queries in the prediction of Gamma-hydroxybutyrate (GHB)-related toxicologic admissions in Hungary by performing additive decomposition of time series to identify trend and seasonal components. Monthly data identified GHB-related search volume representing nationwide web interest towards this substance was found to be a significant covariate of admission rates; the seasonal component showed two peaks in the admission rates: one in December/January and another one in May, whereas more admissions on the weekends were observed as compared to weekday data in Hungary. By taking into account the subtle effect sizes of this study, these results suggest that Google Trends data may be useful in forecasting toxicologic admissions on a monthly level, yet a number of limitations should be considered when interpreting these associations. Web search metrics can therefore be used for early warning purposes in the field of toxicology as well. An external validation approach is also suggested by the authors.

Analysis of Google Trends to monitor new psychoactive substance. Is there an added value?

The past decade has seen an increase in the development and availability of a broad category of drugs, known as new psychoactive substances (NPS). NPS are challenging for public health authorities, therefore the two major drug monitoring bodies - the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) and the United Nations Office on Drugs and Crime (UNODC) - have implemented the EU Early Warning System (EWS) and Early Warning Advisory (EWA), respectively. While these monitoring systems are informative, it is difficult to keep up with the constant and rapid developmental rate of NPS. The EMCDDA has recognised the need for an alternative and technologically derived early warning system. The aim of this research is to determine whether Google Trends and drug discussion forum data can be used to complement early warning systems for NPS. Forty-eight substances were used in this study and classed into groups based on their chemical structure, following the UNODC classification system. Google Trends data (time range: 2004-2019) and drug forum data (time range: 2003-2018) were extracted for each substance and visual trend profiles were created for class groups as well as individual substances. Analysis was conducted to determine when a substance first appeared on Google Trends and a drug discussion forum as well as their trends over time. This date of first appearance was then compared to the date the substance was first reported to UNODC. Of the three data sources utilised, substances were most likely to appear on Google Trends first. Amongst the different classes of NPS, discernible trends ('block', 'successive', and 'generational' trends) were observed. These trends reflect the evolution of the manufacture of substances or generations of substances that has been observed in the literature. For example, in the synthetic cannabinoids' category, a generational trend is observed that corresponds to the different generations of synthetic cannabinoids. When comparing Google Trends and Drugs-Forum directly, the order of appearance and duration of presence for substances aligns accurately for most classes. Google Trends showed the emergence, persistence, or transient nature of substances, which could direct the focus of law enforcement, health organisation and laboratory resources towards a limited number of substances. When one considers the reliance of individual information seeking on the Web as well as the prominence of NPS on the Web, it becomes clear that Google Trends and drug discussion forums could be used as a complement to current early warning systems.

Translating Psychedelic Therapies From Clinical Trials to Community Clinics: Building Bridges and Addressing Potential Challenges Ahead

Research exploring the potential of psychedelic-assisted therapies to treat a range of mental illnesses is flourishing, after the problematic sociopolitical history of psychedelics led to the shutdown of clinical research for almost 40 years. Encouraged by positive results, clinicians and patients are now hopeful that further interruptions to research will be avoided, so that the early promise of these therapies might be fulfilled. At this early stage of renewed interest, researchers are understandably focusing more on clinical trials to investigate safety and efficacy, than on longer-term goals such as progression to community practice. Looking to identify and avoid potential pitfalls on the path to community clinics, the authors, a group of Australian clinicians and researchers, met to discuss possible obstacles. Five broad categories of challenge were identified: 1) inherent risks; 2) poor clinical practice; 3) inadequate infrastructure; 4) problematic perceptions; and 5) divisive relationships and fractionation of the field. Our analysis led us to propose some strategies, including public sector support of research and training to establish best practice and optimize translation, and funding to address issues of equitable access to treatment. Above all, we believe that strategic planning and professional cohesion will be crucial for success. Accordingly, our key recommendation is the establishment of a multidisciplinary advisory body, broadly endorsed and representing all major stakeholders, to guide policy and implementation of psychedelic-assisted therapies in Australia. Although these challenges and strategies are framed within the Australian context, we sense that they may generalize to other parts of the world. Wherever they apply, we believe that anticipation of potential difficulties, and creative responses to address them, will be important to avoid roadblocks in the future and keep the "psychedelic renaissance" on track.

Can google trends search inform us about the population response and public health impact of abrupt change in alcohol policy? A case study from India during the covid-19 pandemic

Background

Sudden alcohol prohibition in India during the COVID-19 pandemic presented an opportunity to test whether Google Trends data could indicate population responses and the public health impact of alcohol policy. We hypothesized, following prohibition: there would be a significant change in the relative search volumes (RSV) of alcohol-related queries; that temporal analysis of the trends would reflect a public response to policy changes; and that geospatial analysis of RSV would correlate with the prevalence of alcohol use.

Methods

Three different search periods were used to test the hypotheses. The search inputs were based on potential public response to alcohol prohibition, as evidenced by the literature, newspaper articles, and consensus. We used RSV as the unit of analysis. Mean RSV of search queries, pre-post implementation of prohibition, were compared. Smoothing of scatter plots examined the temporal association of trends with policy measures. Multiple linear regression tested the relationship of state-wise RSV and alcohol use prevalence.

Results

Post-implementation of prohibition, a significant increase in the RSV was observed for searches related to alcohol withdrawal (p<0.001), how to extract alcohol from sanitizer (p = 0.002), alcohol home delivery online (p<0.001), alcohol home delivery (p<0.001), and sleeping pills (p = 0.006). The trends suggested a decrease in general interest in alcohol but increased demand, and a possible connection with changes in policy measures. State-level RSV and alcohol use prevalence did not reveal a significant relationship.

Conclusion

Google trend is a potential source of rapid feedback to policymakers about population responses to an abrupt change in alcohol policies.

Public interest in Cannabis during election season: a Google Trends analysis

Introduction

Given that 72% of internet users seek out health information using an internet search engine (Google being the most popular); we sought to investigate the public internet search interest in cannabis as a health topic when cannabis legislation appeared on state ballots and during presidential elections.

Materials and methods

We searched Google Trends for “cannabis” as a health topic. Google Trends data were extracted during the time period of May 1, 2008 to May 1, 2019 for the United States (US) and select states (18) within the US including: Alaska, Arizona, Arkansas, California, Colorado, Florida, Maine, Massachusetts, Michigan, Missouri, Nevada, North Dakota, Ohio, Oregon, Oklahoma, South Dakota, Utah, and Washington when cannabis was on the ballot. These state elections were referenda, not legislative votes. We then compared the internet search interest for cannabis before and after each election. To evaluate whether any associations with changes in the volume of cannabis internet searches were specific to the cannabis topic, or also occurred with other topics of general interest during an election year, the authors ran additional analyses of previously popular debated policies during Presidential Elections that may act as control topics. These policies included Education, Gun Control, Climate Change, Global Warming, and Abortion. We used the autoregressive integrated moving average (ARIMA) algorithm to forecast expected relative internet search interests for the 2012 and 2016 Presidential Elections. Individual variables were compared using a linear regression analysis for the beta coefficients performed in Stata Version 15.1 (StataCorp).

Results

Public internet search interest for “cannabis” increased during the voting month above the previous mean internet search interest for all 18 bills. For the US, observed internet search interest during each Presidential Election was 26.9% [95% CI, 18.4–35.4%] greater than expected in 2012 and 29.8% [95% CI, 20.8–38.8%] greater than expected in 2016. In 2016, significant state-level findings included an increase in relative internet search rates for cannabis in states with higher usage rates of cannabis in the past month (Coeff (95% CI), 3.4 (2.8–4.0)) and past month illicit drug use except cannabis rates (Coeff (95% CI), 17.4 (9.8–25.0)). Relative internet search rates for cannabis from 2008 to 2019 were also associated with increased cannabis usage in the past month (Coeff (95% CI), 3.1 (2.5–3.7)). States with higher access to legal cannabis were associated with higher relative internet search volumes for cannabis (Coeff (95% CI), 0.31 (0.15–0.46)). Of the five additional policies that were searched as topics, only two showed an increase in internet search interest during each Presidential Election. Climate Change increased by 3.5% [95% CI, − 13-20%] in 2012 and 20.1% [95% CI, 0–40%] in 2016 while Global Warming increased by 1.1% [95% CI, − 19-21%] in 2012 and 4.6% [95% CI, − 6-15%] in 2016.

Conclusion

Based on these results, we expect public interest in cannabis will spike prior to the Presidential election in 2020. Of the five selected control policies, only two showed an increase in internet search interest during both Presidential Elections and neither exceeded the internet search increase of cannabis. These results may indicate the growing awareness of cannabis in the US and mark a possible target for the timely dissemination of evidence-based information regarding cannabis and its usage/side-effects during future elections. Consequently, the results of this study may be important to physicians since they will likely receive an increased volume of questions relating to cannabis and its therapeutic uses during election season from interested patients. We recommend establishing a cannabis repository of evidence-based information, providing physician education, and a dosing guide be created to enable physicians to provide high quality care around the issue of cannabis.

Effects of messaging on public support for drug consumption rooms in scotland, UK

BACKGROUND

There is evidence to suggest that medically supervised drug consumption rooms (DCRs) may form part of responses to reduce drug-related harm. Although DCRs have been established globally, they are perceived by some to be a controversial approach in the UK, and Government has repeatedly rejected proposals to establish one in Glasgow, Scotland. As public support is an important component of policy development and enactment, we sought to investigate the effects of different types of message framing on public support for DCR.

METHODS

We undertook a cross-sectional online study with a randomised design, conducted with a nationally representative sample. Participants were randomised to one of six message conditions comprising combinations of four components. All conditions included i) a basic description of a DCR, and conditions included combinations of ii) factual information; iii) pre-emptive refutation of common public concerns about DCR; and/or iv) a sympathetic narrative describing a mother whose son died from a heroin overdose. After reading each message, participants completed a bespoke measure assessing support for DCR. Data were analysed using ANCOVA.

RESULTS

Complete data were obtained from 1591 participants (50.3% Female; mean age 44.9 ± 16.1 years). Compared to reading a basic description of DCR alone, there was greater support for DCR in participants receiving the refutation (p < .001); sympathetic + factual (p < .05); and sympathetic + factual + refutation (p < .001) message conditions. Presenting factual or sympathetic messages alone were not associated with increased support.

CONCLUSION

Our findings suggest that public support for DCRs is not improved through communication of factual statements outlining potential benefits of the intervention alone. Advocates seeking to foster public support, and thus influence policy making, should also consider communication campaigns that address common concerns that the public might have about DCRs, and present the intervention in relation to potential benefits that they hold for people indirectly affected by drug-related harm.

New psychoactive substances in Australia: patterns and characteristics of use, adverse effects, and interventions to reduce harm

PURPOSE OF REVIEW

To summarize the most recent peer-review literature on new psychoactive substances (NPS) within Australia.

RECENT FINDINGS

NPS use among the general Australian population is low, yet more pervasive among specific subpopulations. There is considerable heterogeneity among people who use NPS, however, overall, they are not unique from those who use more established illicit drugs. NPS have been shown to be highly adulterated, used as contaminants, variable in dose, and changeable as to the specific substances available over time. Further, analyses of coroners' cases highlight the importance of consumer understanding of NPS effects, particularly where they differ substantially to their more traditional illicit drug counterparts (e.g., synthetic vs. plant cannabinoids). One study posited that legislative approaches to NPS have been (partially) effective in reducing harms, and there are new systems being established to identify NPS-related health harms.

SUMMARY

There have been few studies recently published on NPS in Australia (n = 17), however, findings mostly align with the international literature with respect to the rapidly changing nature of the NPS market, the use of NPS as adulterants, and associated harms. These themes highlight the need for proactive, novel approaches to rapidly identify, and respond to emerging drugs of concern.

The rise of new psychoactive substances and psychiatric implications: A wide-ranging, multifaceted challenge that needs far-reaching common legislative strategies

The ever-growing number of novel psychoactive substances (NPS) that have been surfacing globally, as well as related changes in drug abuse trends, undoubtedly constitute a difficult and multifaceted challenge for psychiatry. The intake and abuse of such substances has been linked to a risk of psychopathological disturbances, which stem from imbalances of a range of neurotransmitter pathways and receptors. Through an analysis of relevant research articles and reviews (particularly those outlining NPS neurological and cerebral mechanisms of action and psychopathological consequences arising from NPS abuse; research papers more closely focused on chemical/pharmacological aspects have been ruled out), through a systematic analysis of Pubmed, Medline, PsycLIT and EMBASE literature, as well as data released by health care institutions and drug enforcement agencies (among which the World Health Organization, the United Nations Office on Drugs and Crime, the European Monitoring Centre for Drugs and Drug Addiction, Eurojust, the Novel Psychoactive Treatment UK Network, the Court of Justice of the European Union), the authors aimed to elaborate on the most relevant data relative to NPS-related psychiatric effects, focusing on the conceptual and definition-related complexities inherent to NPS, clinical management and motivations for NPS use; moreover, an effort has been made to highlight the possible measures in order to tackle the unremitting rise of such elusive and potentially harmful substances.

The impact of legislation on acute synthetic cannabinoid harms resulting in ambulance attendance

BACKGROUND

Synthetic cannabinoid receptor agonists (SCRAs) have been challenging current drug policy due to the rapid emergence of new variants, and their propensity for acute harm. In Australia, as in other parts of the world, multiple regulatory changes have occurred in response to these new psychoactive compounds, and population surveys indicate use is declining. This suggests that related harms would also be declining. We examined the impact of drug legislative changes on acute SCRA-related harms resulting in ambulance attendance. Secondary aims were to describe patient and attendance characteristics.

METHODS

A retrospective analysis of coded ambulance attendance data from Victoria, Australia (January 2014-December 2018). Interrupted time-series was used to analyse the trajectories of SCRA-related attendances relative to legislative changes.

RESULTS

During the study period, 3727 SCRA-related ambulance attendances were identified. There was an upward trend in attendances following legislation scheduling specific SCRAs in Victoria in October 2016 (slope = 1.31, 95% CI 1.17, 1.45). A downward trend in attendances followed 'blanket' legislation targeting all new psychoactive substances, implemented in Victoria in November 2017 (slope = -1.87, 95% CI -2.27, -1.46). Patient median age was 33 years, 80.5% were male, co-occurring substance use was identified in 30.4% cases, and 15.2% had >1 SCRA-related attendance. Overall, 69.4% cases were transported to hospital, with the odds of transport to hospital increasing each year from 2016.

CONCLUSION

This study represents a population-level examination of the impact of drug policy on acute SCRA-related harms resulting in ambulance attendance. Scheduling of specific SCRAs was associated with a spike in attendances, likely due to the introduction of more harmful variants in the drug market. Blanket legislation was associated with a reduction in SCRA-related attendances, however, a corresponding increase in cases transported to hospital indicates a greater severity of harm that may have been inadvertently promoted by this policy.

New psychoactive substances: challenges for drug surveillance, control, and public health responses

The rapid emergence since the mid-2000s of a large and diverse range of substances originally designed as legal alternatives to more established illicit drugs (pragmatically clustered and termed new psychoactive substances; [NPS]) has challenged traditional approaches to drug monitoring, surveillance, control, and public health responses. In this section of the Series, we describe the emergence of NPS and consider opportunities for strengthening the detection, identification, and responses to future substances of concern. First, we explore the definitional complexity of the term NPS. Second, we describe the origins and drivers surrounding NPS, including motivations for use. Third, we summarise evidence on NPS availability, use, and associated harms. Finally, we use NPS as a case example to explore challenges and opportunities for future drug monitoring, surveillance, control, and public health responses. We posit that the current means of responding to emerging substances might no longer be fit for purpose in a world in which different substances can be rapidly introduced, and where people who use drugs can change preferences on the basis of market availability.

Synthetic cannabinoid use disorder: an update for general psychiatrists

OBJECTIVE

Synthetic cannabinoid use disorder is emerging as a significant clinical issue. This article provides the general psychiatrist with an overview of the physical and psychiatric adverse effects of chronic synthetic cannabinoid use, as well as specific clinical responses.

METHOD

We performed electronic searches of Ovid MEDLINE and Ovid Embase to identify key articles, of all methodological designs, published up to June 2018.

RESULTS

The available evidence suggests that, compared to cannabis, use of synthetic cannabinoids is associated with the more rapid development of dependence, increased psychiatric risks and complex withdrawal, and serious physical adverse effects that include seizures, cardiotoxicity and death, denoting a potential need for more intensive management.

CONCLUSION

When synthetic cannabinoid use is identified, along with management of acute physical and psychiatric adverse effects, psychotherapeutic strategies to reduce use and/or harm are recommended.

Exploration of the Use of New Psychoactive Substances by Individuals in Treatment for Substance Misuse in the UK

Substance misuse services need to meet the growing demand and needs of individuals using new psychoactive substances (NPS). A review of the literature identified a paucity of research regarding NPS use by these individuals and UK guidelines outline the need for locally tailored strategies. The purpose of this qualitative study was to identify and explore key themes in relation to the use of NPS by individuals receiving community treatment for their substance use. Electronic records identified demographics and semi-structured interviews were undertaken. A thematic analysis of transcripts identified a variety of substance use histories; 50% were prescribed opiate substitutes and 25% used NPS as a primary substance. All were males, age range 26–59 years (SD = 9), who predominantly smoked cannabinoids and snorted/injected stimulant NPS. The type of NPS used was determined by affordability, availability, side-effect profile and desired effects (physical and psychological: 25% reported weight loss as motivation for their use). Poly-pharmacy, supplementation and displacement of other drugs were prevalent. In conclusion, NPS use and associated experiences vary widely among people receiving substance use treatment. Development of effective recovery pathways should be tailored to individuals, and include harm reduction strategies, psychosocial interventions, and effective signposting. Services should be vigilant for NPS use, “on top” use and diversion of prescriptions.

Ideation, social construction and drug policy: A scoping review

Within drug policy scholarship there is a growing body of literature applying ideational and social constructionist approaches to address the complexity of drug policy making and the apparent failure of the evidence-based policy paradigm to free the process from controversy and contestation. Ideational approaches are concerned with the roles played by ideas and beliefs in policy making, while social construction explores the way policy problems are constructed, and agendas are set and delineated by dominant frames and narratives. Interest in these approaches has developed over the last two decades, but has rapidly gained momentum over the last five years. There has been limited reflection on the state of the field, therefore it is timely to conduct a review of the literature to assess the value of these approaches, capture emerging themes and issues, and identify gaps in the literature to support future research directions. Using the Arksey and O'Malley framework, a scoping review was conducted to survey the breadth of the field. Following database and hand searching, 48 studies from 1996 to 2016 were selected for inclusion in the review. A narrative synthesis was undertaken and the literature was grouped into five broad theoretical approaches: ideational policy theory, problem construction, narratives and frames (including media analysis), construction of target populations, and policy transfer and mobilities. The majority of the studies are focused on single countries and drug policy issues, with few studies undertaking comparative work or reflecting on general theoretical developments in the literature. This study found that the Arksey and O'Malley framework was effective in capturing a potentially diverse field of literature and demonstrates the importance of ideational and social constructionist approaches to drug policy scholarship. Further research is required to achieve expanded geographic coverage, test policy making models and undertake comparative work.

Utility of Web search query data in testing theoretical assumptions about mephedrone

OBJECTIVE

With growing access to the Internet, people who use drugs and traffickers started to obtain information about novel psychoactive substances (NPS) via online platforms. This paper aims to analyze whether a decreasing Web interest in formerly banned substances-cocaine, heroin, and MDMA-and the legislative status of mephedrone predict Web interest about this NPS.

METHODS

Google Trends was used to measure changes of Web interest on cocaine, heroin, MDMA, and mephedrone. Google search results for mephedrone within the same time frame were analyzed and categorized.

RESULTS

Web interest about classic drugs found to be more persistent. Regarding geographical distribution, location of Web searches for heroin and cocaine was less centralized. Illicit status of mephedrone was a negative predictor of its Web search query rates. The connection between mephedrone-related Web search rates and legislative status of this substance was significantly mediated by ecstasy-related Web search queries, the number of documentaries, and forum/blog entries about mephedrone.

CONCLUSIONS

The results might provide support for the hypothesis that mephedrone's popularity was highly correlated with its legal status as well as it functioned as a potential substitute for MDMA. Google Trends was found to be a useful tool for testing theoretical assumptions about NPS.

The Flip Side of “Spice”: The Adverse Effects of Synthetic Cannabinoids as Discussed on a Swedish Internet Forum

Background

Synthetic cannabinoids in smoking mixtures (such as Spice) or as raw powder are sold for recreational use as an alternative to herbal cannabis (hashish and marijuana). Although clinical case studies have documented an array of side effects, there is also information available at Internet based drug discussion forums.

Aim

Our study investigates experiences of side effects from use of synthetic cannabinoids, as described and anonymously shared on Swedish online discussion forums.

Methods

A systematic search yielded 254 unique and publicly available self-reports from the Swedish forum flashback.org. These texts were analysed thematically, which resulted in 32 sub-themes, which were combined into three overarching themes.

Results & Conclusion

The experiences of negative side effects were described as (1) Adverse reactions during acute intoxication; (2) Hangover the day after intoxication; (3) Dependency and withdrawal after long-term use. The first theme was characterized by an array of fierce and unpredictable side effects as tachycardia, anxiety, fear and nausea. The acute intoxication reactions were congruent with the side effects published in clinical case studies. The day after intoxication included residual effects of dullness, apathy, nausea and headache. Long-term use resulted in dependency and experiences of being emotionally numb and disconnected. Furthermore, withdrawal was described as sweating, shaking, loss of appetite and insomnia. Both the hangover and the long-term effects have previously been given little scientific attention and need to be investigated further. Drug related Internet discussion forums constitute an overlooked source of information which can aid in the identification of previously unknown risks and effects.

Assessing the experience of using synthetic cannabinoids by means of interpretative phenomenological analysis

Background

New psychoactive substances (NPS) have been increasingly consumed by people who use drugs in recent years, which pose a new challenge for treatment services. One of the largest groups of NPS is synthetic cannabinoids (SCs), which are intended as a replacement to cannabis. While there is an increasing body of research on the motivation and the effects associated with SC use, little is known about the subjective interpretation of SC use by the people who use drugs themselves. The aim of this study was to examine the experiences and personal interpretations of SC use of users who were heavily dependent on SC and are in treatment.

Methods

A qualitative research method was applied in order to explore unknown and personal aspects of SC use. Semi-structured interviews were conducted with six participants who had problematic SC use and entered treatment. The research was conducted in Hungary in 2015. We analyzed data using interpretative phenomenological analysis (IPA).

Results

Participants perceived SCs to be unpredictable: their initial positive experiences quickly turned negative. They also reported that SCs took over their lives both interpersonally and intrapersonally: the drug took their old friends away, and while initially it gave them new ones, in the end it not only made them asocial but the drug became their only friend, it hijacked their personalities and made them addicted.

Conclusions

Participants experienced rapid development of effects and they had difficulties interpreting or integrating these experiences. The rapid alteration of effects and experiences may explain the severe psychopathological symptoms, which may be important information for harm reduction and treatment services. Since, these experiences are mostly unknown and unpredictable for people who use SCs, a forum where they could share their experiences could have a harm reducing role. For a harm reduction point of view of SCs, which are underrepresented in literature, it is important to emphasize the impossibility of knowing the quantity, purity, or even the number of different SC compounds in a particular SC product. Our study findings suggest that despite the adverse effects, including a rapid turn of experiences to negative, rapid development of addiction and withdrawal symptoms of SCs, participants continued using the drug because this drug was mostly available and cheap. Therefore, a harm reduction approach would be to make available and legal certain drugs that have less adverse effects and could cause less serious dependence and withdrawal symptoms, with controlled production and distribution (similarly to cannabis legalization in the Netherlands).

International trends in spice use: Prevalence, motivation for use, relationship to other substances, and perception of use and safety for synthetic cannabinoids

Synthetic cannabinoids (SC), commonly known as Spice, are a class of compounds that share affinity for the cannabinoid receptors. Recreational use of SCs has grown in recent years. A literature search was conducted of national and international organizations as well as peer-reviewed publications describing SC use in non-clinical populations. Our primary goal was summarizing SC use prevalence within the general population from representative surveys. Our secondary goals included describing SC use frequency, motivation for use, the relationship between SC use and use of other substances, and perception of SC use including beliefs about safety and use by peers. Nationally and regionally representative surveys describe lifetime prevalence of SC use in the general population as between 0.2% and 4%. Longitudinal data, though limited, shows decline in SC use with peak use occurring in the late teens and early twenties. Users tend to be males. The majority of SC users report using only a small number of times and use tends to not be sustained. The most common motive for SC use is curiosity. SC users generally report a history of extensive use of other substances. Perception of SC use by others tends to be significantly greater than actual SC use.

New psychoactive substance use among regular psychostimulant users in Australia, 2010-2015

OBJECTIVE

To examine the rates and patterns of new psychoactive substance (NPS) use amongst regular psychostimulant users (RPU) in Australia.

METHOD

Data were obtained from the 2010-2015 Ecstasy and related Drugs Reporting System (EDRS), which comprised a total cross-sectional sample of 4122RPU.

RESULTS

Recent use of 'any' NPS increased from 33% in 2010 to 40% in 2015, although trends of use differed significantly across NPS classes. The correlates associated with NPS use also varied across NPS classes: frequent (i.e. weekly or more) ecstasy users were more likely to report recent phenethylamine use; LSD users were more likely to report recent phenethylamine and tryptamine use; and daily cannabis users were more likely to report recent synthetic cannabinoid use than RPU who had not used NPS. 'Poly' NPS consumers were found to be a particularly high risk group and were significantly more likely to be younger, male, report daily cannabis use, report weekly or more ecstasy use, report recent LSD use, have higher levels of poly drug use, have overdosed on any drug in the past year, and to have engaged in past month criminal activity.

CONCLUSION

NPS use has been established as a significant and ongoing practice amongst our sample of RPU. It appears that RPU seek out NPS with similar properties to the illicit drugs that they are already consuming, with poly NPS consumers found to be a particularly high risk group.

Synthetic Cannabinoids-Further Evidence Supporting the Relationship Between Cannabinoids and Psychosis

Consumption of synthetic mind-altering compounds, also known as "new psychoactive substances," is increasing globally at an alarming rate. Synthetic cannabinoids (SCs) are among the most commonly used new psychoactive substances. They are usually purchased as marijuana-like drugs, marketed as herbal blends and perceived as risk-free by inexperienced users. Yet, contrary to Δ(9)-tetrahydrocannabinol, SCs may lead to severe health consequences, including anxiety, tachycardia, hallucinations, violent behavior, and psychosis. This review focuses on the latest (2010-2015) evidence of psychotic symptoms induced by ingestion of products containing SCs. Reports suggesting that SCs may either exacerbate previously stable psychotic symptoms (in vulnerable individuals) or trigger new-onset psychosis (in individuals with no previous history of psychosis) are reviewed. Pharmacology and toxicology of these compounds are discussed, with particular reference to their psychoactive effects.

The use of google trends in health care research: a systematic review

BACKGROUND

Google Trends is a novel, freely accessible tool that allows users to interact with Internet search data, which may provide deep insights into population behavior and health-related phenomena. However, there is limited knowledge about its potential uses and limitations. We therefore systematically reviewed health care literature using Google Trends to classify articles by topic and study aim; evaluate the methodology and validation of the tool; and address limitations for its use in research.

METHODS AND FINDINGS

PRISMA guidelines were followed. Two independent reviewers systematically identified studies utilizing Google Trends for health care research from MEDLINE and PubMed. Seventy studies met our inclusion criteria. Google Trends publications increased seven-fold from 2009 to 2013. Studies were classified into four topic domains: infectious disease (27% of articles), mental health and substance use (24%), other non-communicable diseases (16%), and general population behavior (33%). By use, 27% of articles utilized Google Trends for casual inference, 39% for description, and 34% for surveillance. Among surveillance studies, 92% were validated against a reference standard data source, and 80% of studies using correlation had a correlation statistic ≥0.70. Overall, 67% of articles provided a rationale for their search input. However, only 7% of articles were reproducible based on complete documentation of search strategy. We present a checklist to facilitate appropriate methodological documentation for future studies. A limitation of the study is the challenge of classifying heterogeneous studies utilizing a novel data source.

CONCLUSION

Google Trends is being used to study health phenomena in a variety of topic domains in myriad ways. However, poor documentation of methods precludes the reproducibility of the findings. Such documentation would enable other researchers to determine the consistency of results provided by Google Trends for a well-specified query over time. Furthermore, greater transparency can improve its reliability as a research tool.

Fascination and Social Togetherness-Discussions about Spice Smoking on a Swedish Internet Forum

Spice is a smoking mixture containing synthetic cannabinoids with psychoactive effects similar to herbal cannabis. It is sold on the Internet and has become popular among young people. The purpose of the present study was to investigate experiences of intoxication induced by Spice, as described on a Swedish internet-based discussion forum. A systematic search yielded 40 reports, which were analyzed using phenomenological method. A total of 7 themes (composed of 27 categories) emerged from the analysis: 1. Spice use as social ritual; 2. Social secretiveness; 3. Intoxication remarks; 4. Well-being and elation; 5. Altered perception of reality; 6. Fears and coping; 7. Unpleasant physical effects. The results show that smoking was a social activity mostly carried out in small peer-groups, and that the substances induced strong intoxication with both positive and negative effects. Despite fears and unpleasant effects, the intoxication was often considered fascinating and rewarding.

Promoting psychology to students: embracing the multiplicity of research foci and method

In order for the discipline of psychology to continue to thrive it is imperative that future students are effectively recruited into the field. Research is an important part of the discipline and it is argued that the nature of psychological research is naturally one of multiplicity in topic and methodology and that promoting and highlighting this should be considered as a potentially effective recruitment strategy. In this study, a snap-shot of current research topics and methodologies was collected based on published papers from one typical academic psychology department in Australia. Fifty articles published in the period 2010–2013 were randomly selected and then grouped using content analysis to form topic clusters. Five main clusters were identified and included: Grief and Loss; Psychopathology; Sociocultural Studies; Attachment and Parenting; and Developmental Disorders. The studies spanned the full spectrum of research methodologies from quantitative to qualitative and had implications for assessment practices, diagnosis, prevention and treatment, education, and policy. The findings are discussed in terms of the unique characteristics of psychology as a discipline and how this diversity ought to be utilized as the main selling point of the discipline to future students.
