Drug checking at dance festivals: A review with recommendations to increase generalizability of findings

Use of reagent test kits and fentanyl test strips among electronic music festival attendees in Colorado: prevalence, barriers, and behavior in response to drug checking

BACKGROUND

Polysubstance use is common at electronic dance music (EDM) events and hazards associated with polysubstance use may be exacerbated when people who use drugs are unaware of the contents of their drug sample. Reagent test kits (RTK) and fentanyl test strips (FTS) are two efficacious drug checking tools that people who use drugs might use to protect themselves from risks associated with contamination, adulteration, and misrepresentation of unregulated substances. In the current study, we aimed to (1) characterize the use of RTK and FTS among attendees of a 4-day music festival in Colorado and (2) qualitatively capture perceived barriers to using RTK and FTS within festival settings.

METHODS

We surveyed 227 music festival attendees on their use of drug checking tools (i.e., RTK and FTS) and behavior in response to drug checking. We also collected qualitative data on perceived barriers of using RTK and FTS within a festival setting using survey-based open-ended text response questions.

RESULTS

The percentage of participants having ever used RTK and FTS was 75.3% and 66.5% respectively. When asked how often participants ensure their drugs are tested prior to consumption, participants responding "always" or "most of the time" was 54.4% for use of RTK and 59.4% for use of FTS. Additionally, 60.8% of participants reported that they had never consumed a drug that reagent tested differently than expected and 87.9% of participants reported that they had never consumed a drug that tested positive for fentanyl. Perceived barriers to using RTK and FTS within a festival setting encompassed the following themes: (1) accessing testing materials (2) environmental or ecological barriers (3) legal concerns (4) social dynamics (5) lack of education/training and (6) limits of individual drug checking tools.

CONCLUSIONS

RTK and FTS appear to empower festival attendees in the U.S. to make informed decisions related to their substance use. However, there is a critical need to reduce barriers associated with drug checking for this at-risk population.

Welfare first: transforming harm reduction at UK festivals

BACKGROUND

A welfare-first approach to harm reduction at UK festivals is emerging as a critical strategy for enhancing festival safety. In particular, the implementation of anonymous, non-punitive drug-checking services is posited as essential for reducing drug-related harm by enabling informed decision-making. This empirical study examines the limitations of punitive drug policies and the associated risks to public health and explores the potential benefits of decriminalisation in fostering safer festival environments.

METHODS

The study employed qualitative methodologies, including semi-structured interviews and questionnaires with festival attendees at three major UK festivals. This empirical data was supplemented by a review of recent studies (Ivers et al. in Ir J Med Sci 191(4):1701-1710, 2022. https://doi.org/10.1007/s11845-021-02765-2 ; Palmer Maynard in Harm Reduc J 19(1):81, 2022. https://doi.org/10.1186/s12954-022-00662-0 ; Cooney and Measham. in Drug Sci Policy Law 9, 2023. https://doi.org/10.1177/20503245231211444 ) and relevant policy documents, in order to evaluate current harm reduction practices and identify key barriers, such as stigma, social control, and criminalisation.

RESULTS

Analysis revealed that integrated harm reduction measures, comprising drug-checking services, welfare support, and early intervention initiatives, significantly enhance safety by empowering individuals with timely, accurate substance information. A majority of participants expressed a clear preference for drug-checking services, underscoring their willingness to engage when these services are provided in a supportive, non-punitive environment. However, persistent challenges related to punitive drug policies and gaps in public education about harm reduction continue to impede optimal service delivery. Evidence further suggests that a shift towards decriminalisation and welfare-based approaches could mitigate these risks and foster more trusting engagement with harm reduction initiatives.

CONCLUSIONS

The findings indicate that prioritising welfare-first harm reduction strategies, particularly the implementation of anonymous drug-checking services, can create safer festival environments and inform broader public health policies. The study underscores the need for policy reforms that move away from punitive approaches, suggesting that festival-based interventions can serve as scalable models for reducing drug-related harm across diverse community settings.

Investigating an e-cigarette brand's use of music festivals for social media campaigns and experiential marketing

Geek Bar is an e-cigarette brand that has seen a substantial rise in sales in the past year. During this time, the brand has utilized an extensive experiential marketing campaign targeting music and arts festivals, especially electronic dance music (EDM) events. This campaign utilizes both festival attendance and social media to create associations between the brand and EDM culture. To analyze this campaign, we downloaded and coded 18 months of Instagram posts by Geek Bar for the festivals mentioned and relevant themes. During the last six months of data collection, 39% of all Instagram posts by Geek Bar were about festivals. The account regularly drew connections between the brand and EDM culture, showing artists/DJs performing alongside young, attractive e-cigarette users. Such attempts to create ties between the brand and EDM culture are concerning given the younger age of EDM fans. These techniques will likely continue due to the lack of regulations and enforcement on e-cigarettes and experiential marketing.

Examining the use of drug screening technologies in night-time entertainment districts

Background

We sought to determine whether various ion scanner devices could provide a practical alternative in field-based research, where affordable and accessible drug screening is needed for comprehensive and ongoing investigation.

Methods

In Study 1, off-site sample analysis proved inconclusive, rendering Protocols A and B impractical for ongoing drug screening. Conversely, Study 2’s on-site, real-time analysis (Protocol C) emerged as a more effective method. The Itemizer3, particularly in Protocol C, excelled in discerning drug users. Comparing admitted drug use rates in both studies, the mere presence of an objective measure, confirmational or not, likely facilitated more truthful participant responses, highlighting the efficacy of real-time, on-site drug screening using IMS/ITMS technologies.

Findings

All samples analyzed off-site in Study 1 were found to be inconclusive. As such, Protocols A and B were not feasible for on-going drug screening and monitoring. Conversely, the results of Study 2 Protocol C demonstrated that harvesting samples directly off participants on-site and analyzing these in-real time to be a more efficacious method. Our findings in Protocol C also show that the Itemizer3 was better at identifying those who did not use drugs from those who did. Looking at the incidence rates of admitted drug use in Studies 1 and 2, we find that simply having an objective measure present (irrespective of whether it is confirmational or not) likely resulted in us obtaining more truthful responses from participants about their use of drugs.

Conclusions

Our results underscore IMS/ITMS practicality for on-site NED drug screening.

Smartphone swabs as an emerging tool for toxicology testing: a proof-of-concept study in a nightclub

OBJECTIVES

Smartphones have become everyday objects on which the accumulation of fingerprints is significant. In addition, a large proportion of the population regularly uses a smartphone, especially younger people. The objective of this study was to evaluate smartphones as a new matrix for toxico-epidemiology.

METHODS

This study was conducted during two separate events (techno and trance) at an electronic music nightclub in Grenoble, France. Data on reported drug use and whether drugs were snorted directly from the surface of the smartphone were collected using an anonymous questionnaire completed voluntarily by drug users. Then, a dry swab was rubbed for 20 s on all sides of the smartphone. The extract was analyzed by liquid chromatography coupled to tandem mass spectrometry on a Xevo TQ-XS system (Waters).

RESULTS

In total, 122 swabs from 122 drug users were collected. The three main drugs identified were MDMA (n=83), cocaine (n=59), and THC (n=51). Based on declarative data, sensitivity ranged from 73 to 97.2 % and specificity from 71.8 to 88.1 % for MDMA, cocaine, and THC. Other substances were identified such as cocaine adulterants, ketamine, amphetamine, LSD, methamphetamine, CBD, DMT, heroin, mescaline, and several NPS. Numerous medications were also identified, such as antidepressants, anxiolytics, hypnotics, and painkillers. Different use patterns were identified between the two events.

CONCLUSIONS

This proof-of-concept study on 122 subjects shows that smartphone swab analysis could provide a useful and complementary tool for drug testing, especially for harm-reduction programs and toxico-epidemiolgy studies, with acceptable test performance, despite declarative data.

Characterising differences between self-reported and wastewater-identified drug use at two consecutive years of an Australian music festival

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.

Fentanyl Concentration in Drug Checking Samples and Risk of Overdose Death in Vancouver, Canada

INTRODUCTION

The proliferation of fentanyl and its analogs in illegal, unregulated drug markets remains a major driver of the overdose crisis in North America. Drug checking services have been implemented as a harm reduction strategy to address the crisis. However, little is known about their potential utility as a mechanism for monitoring population-level risk of overdose stemming from changing fentanyl concentration in unregulated drugs over time. Therefore, this study assessed the relationship between median fentanyl concentration in expected opioid drug checking samples and the death rate due to illicit drug toxicity over time in Vancouver, Canada.

METHODS

Monthly population-based rates of death due to illicit drug toxicity were drawn from provincial coroner records. Monthly median percent fentanyl concentration was calculated using a validated quantification model from point-of-care Fourier-transform infrared spectra among expected opioid samples that tested positive for fentanyl at community drug checking services. A time-series analysis using generalized additive modeling was conducted to examine the association between monthly median fentanyl concentration and monthly death rate due to illicit drug toxicity, controlling for calendar month. Analyses were conducted in 2021-2022.

RESULTS

Between January 2019 and October 2020, 577 deaths due to illicit drug toxicity occurred in Vancouver, and the observed monthly rate ranged from 1.75 to 7.65 deaths per 100,000 population. A significant, positive association was observed between monthly median fentanyl concentration and monthly death rate due to illicit drug toxicity, adjusting for calendar month (chi-square=52.21, p<0.001).

CONCLUSIONS

Findings suggest a role for point-of-care drug checking as a tool for monitoring evolving overdose risk at the population level.

First drug-checking study at an electronic festival and fentanyl detection in the central region of Mexico

BACKGROUND

Perception of drug adulteration has increased in Mexico, but there is little research on adulterants and toxicity. The aim of this study was to identify drug composition in an electronic music outdoor festival nearby Mexico City.

METHODS

The participants completed a questionnaire with demographic data, harm reduction strategies, drug-use patterns, history, and the drug they expected to find. We took a small sample of each substance and prepared it for drug checking. A two-section drug testing station was placed within the grounds of the festival. Interaction with participants occurred at the front part. Drug checking was conducted at the rear part. The service was free of charge, voluntary and confidential. Forty persons aged 22 to 48 years participated (mode = 28), of which 92.5% were male, most (82.5%) were single. Through the Substance Analysis Program of "ReverdeSer Collective," we conducted the testing with the attendants that provided 51 drug samples, following ethical and biosafety protocols. We used colorimetry, Fourier Transform Infrared Spectroscopy, and fentanyl immunoassay strips for sample analysis.

RESULTS

Substances of choice among attendants were psychostimulants (MDMA and other amphetamine-like drugs) and hallucinogens. Most samples contained what the users expected plus adulterants. Main adulterants were methylene-dioxy-ethyl-amphetamine, methylene-dioxy-propyl-amphetamine, hydroxyamphetamine, and the selective serotonin reuptake inhibitor venlafaxine. Fentanyl was present in 2 out of 4 cocaine samples and in 14 of the 22 confirmed MDMA samples.

CONCLUSIONS

Some of the adulterants found pose serious health risks, especially fentanyl, amphetamine-like substances, and venlafaxine. Therefore, it is urgent to monitor these adulterants at electronic music festivals and to implement prevention, treatment, and harm reduction public policies. Naloxone distribution and drug-assisted therapies should be part of government programs in Mexico.

Exploring the subjective experience of rave party participants in Israel who consume psychedelic drugs: a qualitative inquiry

BACKGROUND

Rave music parties (RMP) are a world-wide socio-cultural phenomenon, where people listen to rave music while frequently consuming psychedelic drugs. Epidemiological studies have emphasized the hazardous consequences following the consumption of psychedelic drugs at RMP, and qualitative studies have shown social and psycho-spiritual experiences. Yet, phenomenological inquiry into subjective experiences of attendees is scant. This study aimed to examine physical, emotional, perceptual and social experiences of RMP participants in Israel, and their view on Israel's policy toward rave events. In addition, the study aimed to contribute useful information for policymakers and society on rave music and psychedelic drugs experiences at RMP.

METHOD

Interpretative phenomenological analysis was used to analyze transcriptions of semi-structured interviews with 27 individuals attending RMP regularly and consume psychedelic drugs.

RESULTS

Analysis revealed four significant themes: the first theme, the impact of Israel's drug policy on participants' sense of safety, relates to participants' sense of insecurity and anxiety at Israeli RMP due to government drug ban policy. The second theme, the stigma on rave culture, relates to participants' perception regarding the stigma on rave culture in law enforcement agencies and in society in general. The third theme, negative experiences, describes short-term experiences after consuming psychedelics at RMP, including hallucinations and disorientation. The fourth theme, positive experiences, describes positive sensory, emotional and self/world attitudinal aspects after consuming psychedelics at RMP. Sensory experiences included intensified auditory, visual and tactile experiences; emotional experiences included positive feelings toward others, reduced stress and ability to vent difficult emotions; self/world attitudinal aspects included self-acceptance, higher appreciation of life and connectedness to nature.

CONCLUSIONS

The study highlights RMP participants' sense of insecurity due to Israel's strict drug policy and absence of harm reduction strategies at rave scenes. The study also notes participants' experience of stigmatization as drug addicts by society and law enforcement agencies. Reducing police presence and adopting harm reduction policies at rave scenes in Israel may increase participants' sense of security, reduce stigmatization and decrease overdose risk. Hence, the findings may contribute to new knowledge useful for policymakers and society concerning RMP and the use of psychedelics.

Prevalence of fentanyl in methamphetamine and cocaine samples collected by community-based drug checking services

BACKGROUND

Overdose deaths involving stimulants and opioids simultaneously have raised the specter of widespread contamination of the stimulant supply with fentanyl.

METHODS

We quantified prevalence of fentanyl in street methamphetamine and cocaine, stratified by crystalline texture, analyzing samples sent voluntarily to a public mail-in drug checking service (May 2021-June 2023). Samples from 77 harm reduction programs and clinics originated in 25 US states. Sample donors reported expected drug and physical descriptions. Substances were identified by gas chromatography-mass spectrometry. Negative binomial models were used to calculate fentanyl prevalence, adjusting for potential confounders related to sample selection. We also examined if xylazine changed donors' accuracy of detecting fentanyl.

RESULTS

We analyzed 718 lab-confirmed samples of methamphetamine (64%) and cocaine (36%). The adjusted prevalence of fentanyl was 12.5% (95% CI: 2.2%, 22.9%) in powder methamphetamine and 14.8% (2.3%, 27.2%) in powder cocaine, with notable geographic variation. Crystalline forms of both methamphetamine (Chisq=57, p<0.001) and cocaine (Chisq=18, p<0.001) were less likely to contain fentanyl: less than 1% of crystal methamphetamine (2/276) and no crack cocaine (0/53). Heroin was present in 6.6% of powder cocaine samples. Xylazine reduced donors' ability to detect fentanyl, with correct classification dropping from 92% to 42%.

CONCLUSIONS

Fentanyl was detected primarily in powder forms of methamphetamine and cocaine. Recommended interventions include expanding community-based drug checking, naloxone and fentanyl test strip distribution for people who use stimulants , and supervised drug consumption sites. New strategies to dampen variability in street drug composition are needed to reduce inadvertent fentanyl exposure.

Pre-Loading with Drugs before Entering the Nighttime Entertainment District: A Scoping Review

Background: Nighttime entertainment districts attract many people who pre-load with alcohol and other substances before entering licensed venues. Despite the harms and dangers associated with both alcohol pre-loading and drug use respectively, there is a paucity of research on drug and polysubstance pre-loading. Objectives: The primary objectives of this scoping review are to systematically map out the body of existing literature on drug and polysubstance pre-loading, discuss methodological potentials and pitfalls in field-based research, identify gaps in knowledge, and derive practical implications and opportunities for future research. Methods: Using the PRISMA (ScR) guidelines, we conducted a search of Medline, PsycINFO, Embase, Scopus, CINAHL, Social Services Abstracts, Sociological Abstracts, and Web of Science databases. We followed this up by conducting an author and citation analysis of relevant articles. Results: Of the 632 data sources identified, 338 articles were reviewed after removing duplicates. Overall, only nine articles were included and thematically analyzed. In our review and analysis of the literature, we find people who drug pre-load to be a particularly vulnerable subset of the population. We also posit that the point-of-entry design has greater sensitivity than the commonly used portal-in design. From this, we also draw attention to various time points where field-based researchers can provide intervention. Conclusions: Given the high prevalence of young adults engaging in the behavior, clinicians should consider pre-loading behaviors when assessing for risk and vulnerability. Field-based research would elucidate the full breadth and scope of the growing pre-loading phenomenon and the dangers associated with this practice.

Insights from Drug Checking Programs: Practicing Bootstrap Public Health Whilst Tailoring to Local Drug User Needs

The year 2021 was the most deadly year for overdose deaths in the USA and Canada. The stress and social isolation stemming from the COVID-19 pandemic coupled with a flood of fentanyl into local drug markets created conditions in which people who use drugs were more susceptible to accidental overdose. Within territorial, state, and local policy communities, there have been longstanding efforts to reduce morbidity and mortality within this population; however, the current overdose crisis clearly indicates an urgent need for additional, easily accessible, and innovative services. Street-based drug testing programs allow individuals to learn the composition of their substances prior to use, averting unintended overdoses while also creating low threshold opportunities for individuals to connect to other harm reduction services, including substance use treatment programs. We sought to capture perspectives from service providers to document best practices around fielding community-based drug testing programs, including optimizing their position within a constellation of other harm reduction services to best serve local communities. We conducted 11 in-depth interviews from June to November 2022 via Zoom with harm reduction service providers to explore barriers and facilitators around the implementation of drug checking programs, the potential for integration with other health promotion services, and best practices for sustaining these programs, taking the local community and policy landscape into account. Interviews lasted 45-60 min and were recorded and transcribed. Thematic analysis was used to reduce the data, and transcripts were discussed by a team of trained analysts. Several key themes emerged from our interviews: (1) the instability of drug markets amid an inconsistent and dangerous drug supply; (2) implementing drug checking services in dynamic environments in response to the rapidly changing needs of local communities; (3) training and ongoing capacity building needed to create sustainable programs; and (4) the potential for integrating drug checking programs into other services. There are opportunities for this service to make a difference in overdose deaths as the contours of the drug market itself have changed over time, but a number of challenges remain to implement them effectively and sustain the service over time. Drug checking itself represents a paradox within the larger policy context, putting the sustainability of these programs at risk and challenging the potential to scale these programs as the overdose epidemic worsens.

The Future of the United States Overdose Crisis: Challenges and Opportunities

Policy Points People are dying at record numbers from overdose in the United States. Concerted action has led to a number of successes, including reduced inappropriate opioid prescribing and increased availability of opioid use disorder treatment and harm-reduction efforts, yet ongoing challenges include criminalization of drug use and regulatory and stigma barriers to expansion of treatment and harm-reduction services. Priorities for action include investing in evidence-based and compassionate policies and programs that address sources of opioid demand, decriminalizing drug use and drug paraphernalia, enacting policies to make medication for opioid use disorder more accessible, and promoting drug checking and safe drug supply.

Substances from unregulated drug markets - A retrospective data analysis of customer-provided samples from a decade of drug checking service in Zurich (Switzerland)

BACKGROUND

Drug checking services (DCS) are harm reduction interventions for people who consume illicit substances. Unregulated drug markets lead to samples with unexpected and variable contents. A retrospective data analysis of Zurich's DCS was performed to determine the nature of these samples.

METHODS

This study aims to investigate the qualitative and quantitative properties of 16,815 customer-provided psychoactive drug samples analyzed chemically through the DCS in Zurich from 1^st January 2011 to 31^st December 2021. The main analytical method utilized for characterizing these substances was high-performance liquid chromatography and gas chromatography-mass spectrometry. Data sets are summarized using descriptive statistics.

RESULTS

There was a 2.5-fold increase in the number of tested samples over the past decade. An overall proportion of 57.9% (weighted mean) of samples within our database demonstrates unexpected analytical findings and additional low sample contents during the observation period. Substantial differences in quality and quantity between substance groups were detected and an increase of sample quality and content over time was demonstrated.

CONCLUSIONS

Chemical analysis reveals that over half of substances acquired from unregulated drug markets analyzed through DCS in Zurich are with low qualitative and quantitative properties, which may expose users to risks. Based on longitudinal analyses over a decade, this study contributes to the body of evidence that DCS may potentially manipulate unregulated drug markets towards providing better quality substances, as well as may stabilize these markets over time. The necessity for drug policy changes to make this service accessible in further settings was highlighted, as DCS still often take place in legal grey zones.

Evaluating new simplified assays for harm reduction from methanol poisoning using chromotropic acid kits: An analytical study on Indian and Iranian alcoholic beverages

Background

Ingestion of methanol can result in severe irreversible morbidity, and death. Simple and easy methods to detect methanol and other hazardous additives prior to consumption can prevent fatalities. This form of harm reduction is analogous to the widely practiced "pill testing" of recreational drugs in various countries. We aimed to evaluate the performance of two qualitative and quantitative kits to simultaneously identify the presence of methanol and formaldehyde in alcoholic beverages, and compare this to the standard gas chromatographic (GC) method.

Methods

Two-hundred samples of Indian and Iranian alcoholic drinks were examined by two new qualitative and quantitative chemical kits designed based on a modified chromotropic acid (CA) method, as well as a gold standard GC method.

Results

Methanol levels were similar when evaluated by GC and quantitative method (Z = - 0.328, p = 0.743). The 75th percentile of methanol level detection was 4,290 mg L^-1 (range; 0-83,132) using GC compared to that of 4,671 mg L^-1 (range; 0-84,960) using the qualitative kit (predefined color intensity reflecting the methanol/ethanol ratio). The quantitative kit was able to detect all methanol-contaminated and non-contaminated samples (110 and 60 cases, respectively: 100% sensitivity). In 25 samples, GC analysis showed no methanol; but the qualitative kit detected possible toxic substances. Formaldehyde measurement by UV/Vis analysis showed the presence of formaldehyde in 23 samples (92%) with a median 912 [IQR 249, 2,109; range 112-2,742] mg L^-1.

Conclusion

Methanol and formaldehyde can be easily detected using these simple CA chemical kits. Qualitative positive results may indicate the risk of poisoning if the beverage is consumed. CA kits can be used in community setting by public health units and community organizations to monitor for methanol contamination and inform a public health response to reduce methanol-related harms to the public.

Take-home drug checking as a novel harm reduction strategy in British Columbia, Canada

BACKGROUND

Drug checking is a harm reduction strategy used to identify components of illicitly obtained drugs, including adulterants, to prevent overdose. This study evaluated the distribution of take-home fentanyl test strips to people who use drugs (PWUD) in British Columbia, Canada. The primary aim was to assess if the detection of fentanyl in opioid samples was concordant between a take-home model and testing by trained drug checking staff.

METHODS

Take-home fentanyl test strips were distributed at ten sites providing drug checking services from April to July 2019. The fentanyl positivity of the aggregate take-home and on-site drug checking groups were compared by class of substance tested. An administered survey assessed acceptability and behaviour change.

RESULTS

1680 take-home results were obtained from 218 unique participants; 68% of samples (n=1142) were identified as opioids and 23% (n=382) were stimulant samples. During this period, 852 samples were tested using on-site drug checking. The fentanyl positivity of opioid samples was 90.0% for take-home samples and 89.1% for on-site samples (Difference 0.8% (95% CI -2.3% to 3.9%)). These results were not affected by previous experience with test strips. Fentanyl positivity of stimulants in the take-home group was higher than on-site (24.7% vs. 3.2%), but the study was underpowered to conduct statistical analysis on this sub-group. When fentanyl was detected, 27% of individuals reported behaviour change that was considered safer/positive. Greater than 95% of participants stated they would use fentanyl test strips again.

CONCLUSIONS

Take-home fentanyl test strips used by PWUD on opioid samples can provide similar results to formal drug checking services and are a viable addition to existing overdose prevention strategies. Use of this strategy for detection of fentanyl in stimulant samples requires further evaluation. This intervention was well accepted and in some participants was associated with positive behaviour change.

Drug policing down under: An investigation of panic consumption, internal concealment and the use of drug amnesty bins among a sample of Australian festivalgoers

BACKGROUND

The use of drug detection dogs and other punitive policing methods remain common at music festivals in Australia and elsewhere, despite concern about iatrogenic effects and recommendations for their overhaul. While drug amnesty bins are a commonly implemented strategy purported to mitigate risk associated with policing, the efficacy of this intervention is debated. This paper investigates two of the most concerning iatrogenic effects of drug policing practices at Australian festivals - internal concealment and panic consumption - and explores the potential efficacy of drug amnesty bins.

METHODS

A stepped, mixed methods study (qual→QUANT→qual) comprised qualitative interviews with key informants and festivalgoers, and a quantitative online survey completed by almost 2000 Australian festivalgoers (52% male; median age 20 years old). Descriptive statistics were performed alongside bivariable and multivariable logistic regressions predicting internal concealment and panic consumption. Inductive thematic analysis was used to examine the qualitative data.

RESULTS

Among respondents who had ever used illicit drugs at festivals (n=1065), 23% reported hiding drugs internally to evade police detection and 17% reported panic consumption. Female respondents and respondents expecting dogs were at greater odds of reporting internal concealment. The qualitative data provided greater insight into the risky nature of internal concealment practices and panic incited by police at the gates. When asked if they would have considered discarding their drugs into a drug amnesty bin had they been concerned about detection, less than a quarter (24%) said they definitely or probably would have.

CONCLUSION

This paper adds to the evidence regarding iatrogenic effects of punitive drug policing practices at festivals. The findings have implications for shifting away from punitive policies to ones focused on public health. Additionally, the findings suggest drug amnesty bins should not be viewed as an adequate response for averting harms from drug policing.

Legality of drug checking equipment in the United States: A systematic legal analysis

BACKGROUND

Fentanyl and fentanyl analogs are increasingly prevalent in the nation's illicit drug supply. While fentanyl-related deaths were previously confined largely to states east of the Mississippi, they are now increasing rapidly throughout much of the United States. Contaminants other than fentanyl are also present in illicitly obtained drugs. Using drug checking equipment to determine the contaminants that may be present in these drugs is a promising avenue for reducing overdose-related harm.

METHODS

Systematic legal review in which three trained legal researchers collected, reviewed, and coded all US state laws that specify whether the possession and distribution of drug checking equipment is generally legal, whether is it legal in the context of syringe services programs, and, where possession or distribution of drug checking equipment is not clearly legal, the potential penalties for violation.

RESULTS

We find that it is clearly legal to possess some or all drug checking equipment in 22 states, and clearly legal to distribute it to adults in 19 states. In 14 states where distribution of drug checking equipment is not clearly legal generally, it is legal when that equipment is obtained from a syringe services program. Potential penalties for violations range from small civil fines to multi-year jail sentences.

CONCLUSIONS

There are currently great variations between states regarding the legality of drug checking equipment. Clarifying, modifying, or repealing drug paraphernalia laws would likely improve access to these promising technologies, potentially reducing overdose deaths.

Drug checking services for people who use drugs: a systematic review

BACKGROUND AND AIMS

Drug checking services provide people who use drugs with chemical analysis results of their drug samples while simultaneously monitoring the unregulated drug market. We sought to identify and synthesize literature on the following domains: (a) the influence of drug checking services on the behaviour of people who use drugs; (b) monitoring of drug markets by drug checking services; and (c) outcomes related to models of drug checking services.

METHODS

Systematic review. A systematic literature search was conducted in MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, PsycINFO, Scopus, Web of Science and Dissertations and Theses Global. Eligible studies were peer-reviewed articles and conference abstracts or grey literature, published in any language since 1990 and including original data on the domains. We assessed risk of bias for quantitative peer-reviewed articles reporting on behaviour or models of drug checking services using National Institutes of Health tools.

RESULTS

We screened 2463 titles and abstracts and 156 full texts, with 90 studies meeting inclusion criteria. Most (n = 65, 72.2%) were from Europe and used cross-sectional designs (n = 79, 87.7%). Monitoring of drug markets by drug checking services (n = 63, 70%) was the most reported domain, followed by the influence of drug checking services on behaviour (n = 31, 34.4%), including intent to use, actual use and disposal of the drug, and outcomes related to models of drug checking services (n = 17, 18.9%). The most common outcome measures were detection of unexpected substances (n = 50, 55.6%), expected substances (n = 44, 48.9%), new psychoactive substances (n = 40, 44.4%) and drugs of concern (n = 32, 36.5%) by drug checking services.

CONCLUSIONS

Drug checking services appear to influence behavioural intentions and the behaviour of people who use drugs, particularly when results from drug checking services are unexpected or drugs of concern. Monitoring of drug markets by drug checking services is well established in Europe, and increasingly in North America. Concerns about drug contents and negative health consequences facilitate the use of drug checking services; lack of concern; trust in drug sellers; lack of accessibility of drug checking services; and legal and privacy concerns are barriers to use.
