RESUMEN
BACKGROUND: In the context of drug prohibition, potential adulteration and variable purity pose additional health risks for people who use drugs, with these risks often compounded by the outdoor music festival environment. Ahead of the imminent implementation of drug checking services in Queensland, Australia, this study aims to characterise this problem using triangulated survey and wastewater data to understand self-reported and detected drug use among attendees of a multi-day Queensland-based music festival in 2021 and 2022. METHODS: We administered an in-situ survey focusing on drug use at the festival to two convenience samples of 136 and 140 festival attendees in 2021 and 2022 respectively. We compared survey findings to wastewater collected concurrently from the festival's site-specific wastewater treatment plant, which was analysed using Liquid Chromatography Tandem Mass Spectrometry. RESULTS: Most survey respondents (82 % in 2021, 92 % in 2022) reported using or intending to use an illicit drug at the festival. Some respondents reported potentially risky drug use practices such as using drugs found on the ground (2 % in 2021, 4 % in 2022). Substances detected in wastewater but not surveys include MDEA, mephedrone, methylone, 3-MMC, alpha-D2PV, etizolam, eutylone, and N,N-dimethylpentylone. CONCLUSION: Many substances detected in wastewater but not self-reported in surveys likely represent substitutions or adulterants. These findings highlight the benefits of drug checking services to prevent harms from adulterants and provide education on safer drug use practices. These findings also provide useful information on socio-demographic characteristics and drug use patterns of potential users of Queensland's future drug checking service.

BACKGROUND: Drug checking services (DCS) provide harm reduction support and advice to individuals based on chemical analysis of submitted substances of concern. Whilst there are currently no DCS in Scotland, community-based services are being planned in three cities. METHODS: In this paper, we report qualitative findings based on interviews with 43 participants, focused on perceptions of DCS and their implementation. Participants were relevant professionals, those with experience of drug use, and family members of those with experience of drug use. The Consolidated Framework for Implementation Research (CFIR) was used to inform data collection and analysis. We report findings under nine constructs/themes across the five CFIR domains. RESULTS: Participants noted the importance of DCS being implemented in low-threshold, trusted services with a harm reduction ethos, and outlined a range of further service design considerations such as speed of testing, and information provided through the analysis process. In relation to the 'inner setting', a key finding related to the potential value of leveraging existing resources in order to expand both reach and effectiveness of drug trend communication. The approach of local and national police to DCS, and the attitudes of the public and local community, were described as important external factors which could influence the success (or otherwise) of implementation. Bringing together a range of stakeholders in dialogue and developing tailored communication strategies were seen as ways to build support for DCS. Overall, we found high levels of support and perceived need for DCS amongst all stakeholder groups. CONCLUSIONS: Our findings present initial implementation considerations for Scotland which could be further explored as DCS are operationalised. Further, our focus on implementation contexts is relevant to research on DCS more generally, given the minimal consideration of such issues in the literature.

Drug checking services (DCS) enable individuals to voluntarily submit a small amount of a substance for analysis, providing information about the content of the substance along with tailored harm reduction support and advice. There is some evidence suggesting that DCS may lead to behaviour and system change, with impacts for people who use drugs, staff and services, and public health structures. The evidence base is still relatively nascent, however, and several evidence gaps persist. This paper reports on qualitative interviews with forty-three participants across three Scottish cities where the implementation of community-based DCS is being planned. Participants were drawn from three groups: professional participants; people with experience of drug use; and affected family members. Findings focus on perceived harm reduction impacts of DCS delivery in Scotland, with participants highlighting the potential for drug checking to impact a number of key groups including: individual service users; harm reduction services and staff; drug market monitoring structures and networks; and wider groups of people who use and sell drugs, in shaping their interactions with the drug market. Whilst continued evaluation of individual health behaviour outcomes is crucial to building the evidence base for DCS, the findings highlight the importance of extending evaluation beyond these outcomes. This would include evaluation of processes such as: information sharing across a range of parties; engagement with harm reduction and treatment services; knowledge building; and increased drug literacy. These broader dynamics may be particularly important for evaluations of community-based DCS serving individuals at higher-risk, given the complex relationship between information provision and health behaviour change which may be mediated by mental and physical health, stigma, criminalisation and the risk environment. This paper is of international relevance and adds to existing literature on the potential impact of DCS on individuals, organisations, and public health structures.

BACKGROUND: Scotland currently has the highest rates of drug-related deaths in Europe, so drug checking services are being explored due to their potential role in reducing these deaths and related harms. Drug checking services allow individuals to submit presumed psychoactive drug samples for analysis, and then receive individualised feedback and counselling. This paper explores participants' views on the advantages and challenges of three hypothetical service models, to inform future service delivery in Scotland. METHODS: Semi-structured interviews were conducted with 43 people: 27 professional stakeholders, 11 people with experience of drug use, and five family members across three cities. Vignettes were used to provide short descriptions of three hypothetical service models during the interviews. Interviews were audio-recorded, transcribed and analysed using thematic analysis. RESULTS: Participants identified advantages and challenges for each of the three potential service models. The third sector (not-for-profit) model was favoured overall by participants, and the NHS substance use treatment service was the least popular. Participants also noted that multiple drug checking sites within one city, along with outreach models would be advantageous, to meet the diverse needs of different groups of people who use drugs. CONCLUSIONS: Drug checking services need to be tailored to local context and needs, with a range of service models being possible, in order to meet the needs of a heterogeneous group of people who use drugs. Addressing issues around stigma, accessibility, and concerns about the potential impact of accessing drug checking on access to and outcomes of drug treatment, are essential for successful service delivery.

In 2021, during a drug-related death crisis in the UK, the Government published its ten-year drugs strategy. This article, written in collaboration with the Faculty of Public Health and the Association of Directors of Public Health, assesses whether this Strategy is evidence-based and consistent with international calls to promote public health approaches to drugs, which put 'people, health and human rights at the centre'. Elements of the Strategy are welcome, including the promise of significant funding for drug treatment services, the effects of which will depend on how it is utilized by services and local commissioners and whether it is sustained. However, unevidenced and harmful measures to deter drug use by means of punishment continue to be promoted, which will have deleterious impacts on people who use drugs. An effective public health approach to drugs should tackle population-level risk factors, which may predispose to harmful patterns of drug use, including adverse childhood experiences and socioeconomic deprivation, and institute evidence-based measures to mitigate drug-related harm. This would likely be more effective, and just, than the continuation of policies rooted in enforcement. A more dramatic re-orientation of UK drug policy than that offered by the Strategy is overdue.

With rising numbers of drug-related deaths in the UK and globally, exploration of interventions that seek to reduce drug-related harm is essential. Drug checking services (DCS) allow people to submit drug samples for chemical analysis and receive feedback about the sample, as well as harm reduction advice. The use of DCS is often linked to festival and/or nightlife settings and to so-called 'recreational' drug use, but research has also shown the potential of community-based DCS as an intervention serving more varied demographics of people who use drugs, including more marginalised individuals and those experiencing drug dependence. Whilst there is a growing evidence base on the effectiveness of drug checking as a harm reduction intervention, there is still limited evidence of the underlying mechanisms and processes within DCS which may aid implementation and subsequent engagement of people who use drugs. This presents a challenge to understanding why engagement differs across types of DCS, and how best to develop and deliver services across different contexts and for different populations. To explore the contexts and mechanisms which impact engagement in community-based DCS, a realist review was undertaken to synthesise the international evidence for the delivery and implementation of DCS. There were 133 sources included in the review. From these sources the underlying contexts, mechanisms, and outcomes relating to DCS implementation and engagement were developed and refined into seven programme theories. The findings of this review are theoretically novel and hold practical relevance for the design of DCS, with implications for optimisation, tailoring, and implementing services to reach individuals in different settings.

BACKGROUND: The impact of policing practices on the engagement of people who use drugs (PWUD) with harm reduction services is well evidenced. Although the police have traditionally taken an enforcement role in responding to drug use, it is increasingly clear that they can play an important part in multiagency delivery of harm reduction interventions. Despite this, there have been no studies exploring police officer perceptions of drug checking services (DCS), which provide analytical testing of client drug samples alongside harm reduction support and advice. METHODS: Semi-structured interviews were conducted with 10 police officers to explore the policing and legal challenges which could be encountered in the delivery of DCS in Scotland. RESULTS: Participants expressed general support for DCS and described this support as part of a wider organisational shift towards public health-oriented policing. Participants also discussed different potential approaches to the policing of areas surrounding DCS including: formal limits on police presence around the service and/or stop and search powers in relation to personal possession; the effective decriminalisation of personal possession within a specified boundary around the service; and informal agreements between local divisions and DCS outlining expected policing practices. Any formal limitation on the capacity of police officers to respond to community concerns was viewed as problematic and as having the potential to erode public confidence in policing. Participants also highlighted the potential for frontline officers to utilise discretion in ways which could undermine public health goals. Legislative change, or national strategic guidance from relevant stakeholders, was seen as a means of providing 'cover', enabling local divisions to support the operation of drug checking. CONCLUSIONS: Despite a small sample of participants, this study summarises key challenges to be addressed in the implementation and operation of DCS in Scotland, and more widely. The paper concludes with suggested opportunities to develop approaches to policing that can facilitate rather than impede implementation and operation of these services.

Little is known about the other leisure activities of people who engage in kink, including sexual practices and the use of alcohol and other drugs. This article examines the drinking, illicit drug use and sexual practices of people who engage in kink from a novel sample of attendees at an English festival. Of 966 respondents, 64 reported having engaged in kink within the past 12 months. We provide evidence of these respondents' self-reported demographic characteristics, alcohol and other drug use in their lifetime and within the past 12 months, as well as other sexual practices they engaged in. This study illustrates the value of accessing participants through in situ festival fieldwork to understand kink practices, and helps us move beyond notions of clustered risky activities toward a leisure studies approach to understanding the practices of people who engage in kink.
RESUMEN
BACKGROUND: Incorporating 3,4-methylenedioxymethamphetamine (MDMA) as an adjunct to psychotherapy has shown promise in recent years for treating various mental health conditions, particularly those involving trauma. However, concerns about declines in mood and cognition during the days following dosing, also known as 'Blue Mondays', have been raised as limitations to its clinical use. Although these changes have been well-documented among recreational users, there are critical confounds to these reports that limit generalizability to clinically administered MDMA. AIMS: Here, we aimed to evaluate the evidence basis for the negative side effects associated with MDMA as well as inform our understanding of the drug's post-acute effects in a clinical context with an open-label study. METHODS: The current open-label study examined MDMA therapy for alcohol use disorder (AUD; N = 14) and measured mood, sleep quality, illicit MDMA consumption and anecdotal reports after the acute drug effects had worn off. RESULTS: Participants maintained a positive mood during the week following drug administration in a clinical context. Relative to baseline, self-reported sleep quality improved at the 3- and 6-month follow-ups. Finally, no participants reported using or desiring to use illicit MDMA, and the anecdotal reports indicated that they perceived the treatment favourably. CONCLUSION: The results support the overall safety and tolerability of clinically administered MDMA and, importantly, suggest that the 'come downs' previously associated with the substance may be explained by confounds in research relating to the illicit sourcing of the drug and specific environmental setting for recreational consumption.

BACKGROUND: European drug checking services exchange information on drug trends within the Trans European Drug Information (TEDI) network, allowing monitoring and coordination of responses. Starting in Spring 2020, several services detected the synthetic cannabinoid receptor agonist MDMB-4en-PINACA in adulterated low-THC cannabis products. METHODS: Cannabis products suspected of adulteration were analyzed for the presence of MDMB-4en-PINACA by 9 services in 8 countries within the TEDI network. If available, phytocannabinoid analysis was also performed. RESULTS: 1142 samples sold as cannabis in herbal, resin and e-liquid form were analyzed, of which 270 were found to contain MDMB-4en-PINACA. All cannabis samples contained low THC (<1%), except the e-liquids which contained no phytocannabinoids. Three serious health incidents requiring hospitalization after use of an adulterated cannabis sample were reported. CONCLUSION: Adulteration of cannabis with synthetic cannabinoid receptor agonists is a new phenomenon that carries risk for people who use it. Given that cannabis consumers are not a usual target group for drug checking services, services and associated harm reduction interventions could be reconfigured to include them.

BACKGROUND: Drug checking is a health service whose behavioural outcomes have been assessed primarily through reported intentions of service users after receiving healthcare consultations or brief interventions (BIs). This study contributes to the evidence base through utilising a follow-up design to compare outcomes of risk communications on risk management and harm reduction practices both at and after attending drug checking services at three English music festivals in 2017. METHODS: Data were collected and analysed from: (i) 1,482 self-complete questionnaires at sample drop-off; (ii) 1,482 nominated primary service users at 1,482 face-to-face BIs; and (iii) an anonymous online self-report follow-up survey completed by a sub-sample of 130 primary service users (one quarter of legible, functioning email addresses received) followed up three months later. Ten measures (one verified action and nine intentions) were recorded at point of BI and compared with retrospectively reported outcomes and ongoing changes post-BI. RESULTS: Outcomes at follow-up were correlated with actions and intentions at BI for nine of the ten measures, including over half of service users disposing of samples identified as other than expected and two in five reporting reduced dosage for samples identified as expected. One in five reported alerting their friends to substances of concern. CONCLUSION: Event-based drug checking services can access and engage productively with young adults earlier in drug taking careers and not in touch with health services, through tailored polydrug BIs. Rapid identification of substances of concern, dissemination of test results and associated risk communications during and after events through friendship networks, support services and early warning systems suggest that the benefits of drug checking can extend beyond service users and point of BI and can increase strategies and behaviours to reduce drug-related harm such as poisoning and overdose.

BACKGROUND: Globally, non-medical heroin use is generating significant public health and social harms, and drug policy about heroin is a controversial field that encompasses many complex issues. Policy responses to illegal heroin markets have varied from militarized eradication of the opium poppy and harsh punishment of users, to more tolerant harm reduction approaches with decriminalized possession and use. METHODS: This paper reports the outcomes of a multi-criteria decision analysis (MCDA) on four generic regulatory regimes of heroin: prohibition, decriminalisation, state control and free market. Invited experts on drug harms, addiction, criminology and drug policy developed a comprehensive set of 27 policy outcome criteria against which these drug policy regimes were assessed. RESULTS: State control of heroin was identified as the preferred policy option although other policy regimes scored better on specific outcome criteria. The free market model scored better than decriminalisation, with absolute prohibition scoring worst on every criterium. The ranking of the regimes was robust to variations in the criterion-specific weights. CONCLUSION: The implications of these findings for the development of future policy responses to heroin and opioids generally are discussed in detail. Despite increasing overdose deaths and an opioid epidemic in North America, prohibition remains the predominant policy approach to heroin regulation at present. It is hoped that the current paper adds to the discussion of finding a valid regulatory alternative.

BACKGROUND: Online sampling is widely used to recruit hard to reach samples such as drug users at nightlife events. We conducted the first study comparing differences in demographics, drug use and nightlife behaviour between an online sample of young adults engaging with the European nightlife scene, and an offline sample recruited at nightclubs and festivals in Europe. METHODS: Online participants who attended at least six nightlife events in the past 12 months were recruited using social media advertising (May-November 2017). Offline participants were recruited at nightclubs and festivals using a random intercept method (May-November 2017). Samples were compared with respect to age, gender, past year use of alcohol, cannabis, cocaine, ecstasy/MDMA and amphetamines, and past year attendance at nightclubs, licensed festivals, illegal festivals, pubs and house-parties. RESULTS: 6153 online and 3529 offline participants were recruited. When adjusting for differences in age and gender, online participants were less likely to have used each drug and to have attended illegal festivals, pubs and house-parties in the past 12 months. The online sample also used each drug and attended each venue, with the exception of nightclubs, less frequently on average than offline participants. Adjusted odds ratios (range 0.37 to 1.39) and regression coefficients (range -0.84 to 0.07) indicate that the majority of observed differences between the samples were of a small effect size. CONCLUSIONS: Estimates of drug use and nightlife engagement are more conservative when using online sampling compared to venue based sampling. Observed differences were generally small in effect, indicating good overall representativeness when using online sampling in the European nightlife scene.

AIMS: To explore the feasibility of delivering community-based drug safety testing (drug checking), to trial service design characteristics and to compare with festival-based testing. METHODS: In total, 171 substances of concern were submitted on 5 dates at 3 venues in 2 UK cities and tested using up to 6 analytical techniques. Test results and harm reduction advice were distributed directly to over 200 service users through 144 tailored healthcare consultations, to stakeholders, and through early warning systems, media and social media alerts. RESULTS: The 171 samples were submitted and identified as MDMA (43.3%), cocaine (12.9%), ketamine (12.9%), various psychedelics submitted by students, and heroin and a synthetic cannabinoid submitted by rough sleeping communities, with 76% of samples' test results as expected. The 144 primary service users identified as 91.7% white, 68.1% male, with an average age of 26.7 years. Reported harm reduction intentions included alerting friends and acquaintances (37.5%), being more careful mixing that substance (35.4%), lowered dosage (27.8%), disposal of further substances (6.9%) and additionally 2.8% handed over further substances for verified destruction. CONCLUSION: Community-based drug safety testing (drug checking) was piloted for the first time in the UK-within a drugs service, a community centre and a church-with consideration given to meso-level operational feasibility and micro-level behavioural outcomes. Service design characteristics such as venue, day of week, prior publicity, service provider, and direct and indirect dissemination of results all may impact on outcomes. Future studies should consider cost-benefit analyses of community and event-based testing and context-appropriate macro, meso and micro-level evaluations.

BACKGROUND: In a year when UK drug-related deaths and festival drug-related deaths reached their highest on record, a pilot festival drug safety testing service was introduced with the aim of reducing drug-related harm. This paper describes the operational and behavioural outcomes of this pilot and explores the relationship between drug use, supply and policing within festival grounds. METHODS: Chemists in a temporary laboratory analysed 247 substances submitted by the public to a free, confidential testing service across four days at a UK festival in July 2016. Test results were returned to service users embedded in 230 healthcare consultations delivered to approximately 900 festival-goers (one in five drug using festival-goers) that included harm reduction advice and the opportunity to use a disposal service for further substances of concern. Consultation data were collected at point of care, matched with test results, coded and analysed using SPSS RESULTS: Test results revealed that one in five substances was not as sold or acquired. One in five service users utilised the disposal service for further substances of concern in their possession and another one in six moderated their consumption. Two thirds of those whose sample was missold disposed of further substances, compared with under one in ten whose sample was as sold. Service users who acquired substances onsite at the festival were more than twice as likely to have been missold them as those acquired offsite, were nearly twice as likely to use the disposal service and were on average two years younger. Women were more likely to be using the drug for the first time and more likely to use the disposal service. Test results were shared with emergency services; alerts issued across site and an unanticipated feedback loop occurred to some drug suppliers. CONCLUSION: This pilot suggests that festival-goers engage productively with onsite drug safety testing services when given the opportunity, such services can access harder-to-reach and new user groups and can play a part in reducing drug-related harm by identifying and informing service users, emergency services and offsite drug using communities about substances of concern. Disposals to the testing service for onward police destruction provide an externally corroborated measure of impact, reducing harm to the individual and others by removing such substances from site. Evidence of differential dealing onsite and its potential negative consequences has implications for future research and policing.

BACKGROUND: Drug policy, whether for legal or illegal substances, is a controversial field that encompasses many complex issues. Policies can have effects on a myriad of outcomes and stakeholders differ in the outcomes they consider and value, while relevant knowledge on policy effects is dispersed across multiple research disciplines making integrated judgements difficult. METHODS: Experts on drug harms, addiction, criminology and drug policy were invited to a decision conference to develop a multi-criterion decision analysis (MCDA) model for appraising alternative regulatory regimes. Participants collectively defined regulatory regimes and identified outcome criteria reflecting ethical and normative concerns. For cannabis and alcohol separately, participants evaluated each regulatory regime on each criterion and weighted the criteria to provide summary scores for comparing different regimes. RESULTS: Four generic regulatory regimes were defined: absolute prohibition, decriminalisation, state control and free market. Participants also identified 27 relevant criteria which were organised into seven thematically related clusters. State control was the preferred regime for both alcohol and cannabis. The ranking of the regimes was robust to variations in the criterion-specific weights. CONCLUSION: The MCDA process allowed the participants to deconstruct complex drug policy issues into a set of simpler judgements that led to consensus about the results.
