“You can't go wrong being safe”: Motivations, patterns, and context surrounding use of fentanyl test strips for heroin and other drugs

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.

Rethink Recovery: A Qualitative Approach to Exploring Messaging for Medication-Assisted Recovery (MAR)

Similar to national trends, in Illinois, fatal opioid overdoses have risen. Black men (35+) outrank all other racial subgroups for the highest rate of fatal opioid overdoses in the state. To address this, Prevention First and the Illinois Department of Human Services developed a public health education campaign to support increasing enrollment in recovery services, with a focus on Black men (35+). Self-reported Black participants with opioid use disorder (OUD) made up the analytic sample. Study goals were to understand lived experiences of the campaign audience; investigate knowledge, attitudes, and beliefs regarding OUD and treatment; explore perceived barriers and facilitators to treatment; and evaluate messaging that showcased medication-assisted recovery (MAR) as a viable tool for treatment and recovery. Interviews were recorded and transcribed for thematic analysis. Participants shared long and cyclical journeys of use and recovery. Participants had low levels of knowledge of available treatment options and struggled to imagine themselves in recovery because of the fear of cravings and withdrawal. Messaging that was realistic about the cyclical nature of recovery, showed the varying options for MAR, and addressed cravings and withdrawals were well received. These findings illustrate the importance of understanding an audience and involving them in campaign development to create messaging that promotes behavior change and sustained health. Through the Decision Blocks strategic framework, we discovered information gaps, barriers to treatment, and practical solutions to increase access to treatment for Black men with OUD that has been limited due to inequities caused by structural racism.

Prevalence and drug use correlates of inadvertent fentanyl exposure among individuals misusing drugs in seven U.S. states

Fentanyl has emerged as the leading cause of fatal drug overdoses in the U.S. Individuals misusing drugs may not always be aware of exposure to fentanyl.

To determine the prevalence of fentanyl use and extent of awareness of fentanyl exposure among a national sample of treatment-seeking individuals with opioid use disorder (n = 1098).

Participants provided oral fluid and urine specimens, which were tested for drugs by liquid chromatography/tandem mass spectrometry. Participants also provided self-reports of fentanyl use.

49.5% tested positive for fentanyl in oral fluid, urine, or both. Of those testing positive for fentanyl, 29.8% were unaware that they had been exposed to fentanyl. Participants testing positive for opioids methadone, and specifically 6-monoacetylmorphine (6-MAM), a unique metabolite of heroin, were significantly more likely to be unaware of fentanyl exposure than participants testing negative for these substances, with a similar trend for oxycodone and tramadol.

These findings may be due to fentanyl's effect being difficult to distinguish from that of other opioids, whereas when other types of drugs are adulterated with fentanyl, the differences in effects are likely to be readily discernable. These results support the importance of expanded drug-checking services.

"If everyone knew about this, how many lives could we save?": Do drug suppliers have a role in reducing overdose risk?

Introduction

An unpredictable illicit drug supply is driving high levels of overdose death in North America. Prior research has demonstrated the importance of involving people who use drugs in harm reduction intervention design and implementation. The inclusion of people who supply drugs in these efforts has been scant. We explore this possibility by interviewing persons targeted by a harm reduction educational program designed specifically for people who supply drugs.

Methods

In-person interviews with people who use drugs were conducted in 2022 in Indianapolis, Indiana. We conducted a thematic analysis of data from six interviews with people who were either primarily or secondarily trained through this harm reduction training for people who supply drugs.

Results

Participants described a diverse array of harm reduction strategies, some gained through the targeted education program, which they regularly practiced as they consumed and/or supplied drugs to others. People who supply drugs were regularly identified as key actors capable of widely reducing risk across drug networks. Participants described being motivated by a moral imperative to protect community members, tying the previous loss of friends and loved ones to overdose to their commitments to the safety of others.

Conclusion

This article contributes to the scholarship on the role of people who supply drugs in implementing harm reduction interventions and reducing overdose risk. Better enabling grassroots harm reduction organizations to provide people who supply drugs with harm reduction training and access to harm reduction resources may help to reduce drug-related harms.

Nitazene test strips: a laboratory evaluation

BACKGROUND

2-Benzylbenzimidazole 'nitazene' opioids pose a growing threat to public health. Nitazene analogues are increasingly found mixed with or (mis)sold as heroin and in falsified (non-)opioid medications, posing a great risk of intoxication in users (un)knowingly exposed to these potent opioids. Lateral flow immunoassay nitazene test strips (NTS; BTNX Rapid Response™) became commercially available in Q1 2024, with the aim to enable rapid detection of nitazene analogues in drug samples. As only limited independent data is available on the performance of these strips, this lab-based study aimed at evaluating their potential for drug checking applications.

METHODS

Following dilution of drug standards in water, the NTS readouts were analyzed independently by two individuals and by ImageJ. The limit of detection for isotonitazene was determined using two manufacturing lots of NTS. Cross-reactivity with 32 other nitazene analogues was evaluated. Six sourced drug samples were tested to explore the ability of NTS to detect the presence of a nitazene analogue in authentic samples.

RESULTS

The limits of detection for isotonitazene were 2000 or 3000 ng/mL, depending on the lot. Twenty-four of the 33 tested nitazene analogues cross-reacted with the NTS at concentrations ≤ 9000 ng/mL. Structural analysis indicated that either substitution or removal of the 5-nitro group, or lengthening the linker between the two aromatic rings, generally hampered detection. All six authentic drug samples consistently tested positive, with no observed false negatives.

CONCLUSIONS

This study provides a better understanding of the potential of NTS for drug checking purposes. Our findings indicate that NTS can theoretically alert to the presence of most nitazene analogues that have emerged on recreational drug markets. However, 'desnitazenes' (lacking the 5-nitro group) may yield false negative results due to low cross-reactivity. Although factors like specificity, lot-to-lot variability, nitazene analogue content in drug samples, solubility, and different testing conditions should be considered, our study results indicate that, at least under the conditions evaluated here (using reference standards and sourced powders), NTS are capable of detecting the presence of a wide range of nitazene analogues. Hence, NTS may alert users of the presence of nitazene analogues in drug samples.

Preventing overdoses involving stimulants: the POINTS study protocol

BACKGROUND

In recent years, overdoses involving illicit cocaine, methamphetamine, and other stimulants have increased in the U.S. The unintentional consumption of stimulants containing illicit fentanyl is a major risk factor for overdoses, particularly in Massachusetts and Rhode Island. Understanding the drug use patterns and strategies used by people who use stimulants (PWUS) to prevent overdose is necessary to identify risk and protective factors for stimulant and opioid-involved overdoses. Mixed-methods research with people who distribute drugs (PWDD) can also provide critical information into the mechanisms through which fentanyl may enter the stimulant supply, and the testing of drug samples can further triangulate PWUS and PWDD perspectives regarding the potency and adulteration of the drug supply. These epidemiological methods can inform collaborative intervention development efforts with community leaders to identify feasible, acceptable, and scalable strategies to prevent fatal and non-fatal overdoses in high-risk communities.

METHODS

Our overall objective is to reduce stimulant and opioid-involved overdoses in regions disproportionately affected by the overdose epidemic. To meet this long-term objective, we employ a multi-pronged approach to identify risk and protective factors for unintentional stimulant and opioid-involved overdoses among PWUS and use these findings to develop a package of locally tailored intervention strategies that can be swiftly implemented to prevent overdoses. Specifically, this study aims to [1] Carry out mixed-methods research with incarcerated and non-incarcerated people who use or distribute illicit stimulants to identify risk and protective factors for stimulant and opioid-involved overdoses; [2] Conduct drug checking to examine the presence and relative quantity of fentanyl and other adulterants in the stimulant supply; and [3] Convene a series of working groups with community stakeholders involved in primary and secondary overdose prevention in Massachusetts and Rhode Island to contextualize our mixed-methods findings and identify multilevel intervention strategies to prevent stimulant-involved overdoses.

DISCUSSION

Completion of this study will yield a rich understanding of the social epidemiology of stimulant and opioid-involved overdoses in addition to community-derived intervention strategies that can be readily implemented and scaled to prevent such overdoses in two states disproportionately impacted by the opioid and overdose crises: Massachusetts and Rhode Island.

Fentanyl Test Strips for Harm Reduction: A Scoping Review

BACKGROUND

High potency synthetic opioids like fentanyl have continued to replace or contaminate the supply of illicit drugs in North America, with fentanyl test strips (FTSs) often used as a harm reduction tool for overdose prevention. The available evidence to support FTS for harm reduction has yet to be summarized.

METHODS

A search of PubMed, Ovid Embase, and Web of Science was conducted in March 2023. A 2-stage review was conducted to screen by title and abstract and then by full text by 2 reviewers. Data were extracted from each study using a standardized template.

RESULTS

A total of 91 articles were included, mostly from North America, predominantly reporting on FTS along with other harm reduction tools, and all conducted after 2016. No randomized controlled trials are reported. Robust evidence exists supporting the sensitivity and specificity of FTS, along with their acceptability and feasibility of use for people who use drugs and as a public health intervention. However, limited research is available on the efficacy of FTS as a harm reduction tool for behavior change, engagement in care, or overdose prevention.

CONCLUSIONS

Though FTSs are highly sensitive and specific for point of care testing, further research is needed to assess the association of FTS use with overdose prevention. Differences in FTS efficacy likely exist between people who use opioids and nonopioid drugs, with additional investigation strongly needed. As drug testing with point-of-care immunoassays is embraced for nonfentanyl contaminants such as xylazine and benzodiazepines, increased investment in examining overdose prevention is necessary.

Opioid-stimulant trends in overdose toxicology by race, ethnicity, & gender: An analysis in Delaware, 2013-2019

Recent upticks of stimulant presence in overdose deaths suggest the opioid epidemic is morphing, which raises questions about what drugs are involved and who is impacted. We investigate annual and growth rate trends in combined opioid-stimulant overdose toxicology between 2013 and 2019 for White, Black, and Hispanic male and female decedents in Delaware. During these years, toxicology shifted to illegal drugs for all with fentanyl leading the increase and opioid-cocaine combinations rising substantially. While combined opioid-cocaine toxicology grew among Black and Hispanic Delawareans, White males continue to report the highest rates overall. These findings depart from historical patterns and may challenge existing opioid epidemic policies.

Safety strategies and harm reduction for methamphetamine users in the era of fentanyl contamination: A qualitative analysis

INTRODUCTION

In the United States, methamphetamine use is increasing and the context of its use has changed, with reports of illicitly manufactured fentanyl being mixed with methamphetamine (either deliberately or inadvertently). We explore risk-mitigating actions taken by people who use drugs to protect their health when using methamphetamine in that context.

METHODS

We conducted qualitative interviews with 48 adults (18+) who used methamphetamine in the past three months at two sites in Nevada, USA and two sites in New Mexico, USA. Interviews were recorded, transcribed, and analyzed using thematic analysis.

RESULTS

Respondents described two rationales for employing harm reduction strategies. First, to prevent harm from methamphetamine containing illicit fentanyl, and second, to maintain their general wellbeing while using methamphetamine. Regarding methamphetamine containing illicit fentanyl, our findings highlight how respondents employ primary strategies like buying from trusted sources and secondary strategies such as spotting and selective use of harm reduction tools (i.e., fentanyl test strips) to reduce risks. To maintain their general wellbeing, participants reduced their use of methamphetamine as reasonably as possible, and used other substances like marijuana and alcohol alongside methamphetamine to counter the unwanted side effects of methamphetamine (i.e., hallucinations and paranoia). Use of these harm reduction strategies varied within situational and social contexts, and respondents usually developed these strategies based on their lived experiences.

CONCLUSION

Our findings uniquely demonstrate that people who use methamphetamine prioritize community driven, trust-based strategies within their social networks to mitigate risks in a fentanyl-contaminated drug environment. Additionally, our results indicate that harm reduction behaviors are influenced by multilevel risk environments, which include social, physical, economic, and political factors. Overall, these results highlight the potential for targeted interventions at the network level, which are responsive to complexities and shifts in drug market dynamics- such as illicit fentanyl in methamphetamine.

Correlates of overdose among 2711 people who use drugs and live in 7 rural US sites

BACKGROUND

Overdose rates in rural areas have been increasing globally, with large increases in the United States. Few studies, however, have identified correlates of non-fatal overdose among rural people who use drugs (PWUD). The present analysis describes correlates of nonfatal overdose among a large multistate sample of rural PWUD.

METHODS

This is a cross-sectional analysis of data gathered via surveys with PWUD recruited through seven Rural Opioid Initiative (ROI) sites. Descriptive analyses were conducted to assess the prevalence of past 30-day overdose. Generalized estimating equations were used to estimate a series of multivariable models quantifying relationships of select factors to past-month overdose; factors were selected using the Risk Environment Framework.

RESULTS

The multisite sample included 2711 PWUD, 6% of whom reported overdosing in the past 30 days. In the fully adjusted model, houselessness (AOR=2.27, 95%CI[1.48, 3.48]), a positive test result for Hepatitis C infection (AOR=1.73 95%CI[1.18, 2.52]) and heroin/fentanyl use (AOR= 8.58 95%CI [3.01, 24.50]) were associated with an increased risk of reporting past 30-day overdose, while having a high-school education or less was associated with reduced odds of overdose (AOR=0.52, 95% CI[0.37, 0.74]).

CONCLUSION

As in urban areas, houselessness, Hepatitis C infection, and the use of heroin and fentanyl were significant correlates of overdose. Widespread access to overdose prevention interventions - including fentanyl test strips and naloxone - is critical in this rural context, with particular outreach needed to unhoused populations, people living with Hepatitis C, and people using opioids.

Beyond a spec: assessing heterogeneity in the unregulated opioid supply

BACKGROUND

Drug checking services aim to provide compositional information for the illicit drug supply and are being employed in public health responses to extreme rates of overdose associated with fentanyl within street opioids. The technologies used within these services range from basic qualitative tests, such as immunoassay test strips, to comprehensive quantitative analyses, such as mass spectrometry. In general, there is concern that heterogeneity of a drug mixture adds significant uncertainty when using drug checking results based on a small subsamples. The presence of hot spots of active drug components in this context is often termed the 'chocolate chip cookie effect'. Establishing the limitations of the service are essential for interpretation of the results.

METHODS

This study assesses the consequence of drug heterogeneity and sampling of consumer level opioid purchased in Victoria, British Columbia ( n = 21 , 50-100 mg each) on quantitative fentanyl results determined from testing with paper spray mass spectrometry.

RESULTS

Using descriptive statistics, such as relative standard deviation and interquartile range, the results demonstrate varied distributions of fentanyl concentrations within a single drug batch. However, the presence of hot spots, defined as outliers, were relatively rare.

CONCLUSIONS

This study found that the variability in fentanyl concentration from drug heterogeneity and sampling is greater than that attributed to the analytical technique. On a practical level, this provides data to help guide communication of limitations of drug checking services, supporting the aim of trust and transparency between services and people who use drugs. However, if drug checking services continue to be restricted from fully engaging with the reality of manufacturing, buying, selling, mixing and dosing practices, the accuracy, usefulness, and impact will always be limited.

Making Harm Reduction More Accessible: Fentanyl Test Strip Awareness and Attitudes among Emergency Department Patients Who Use Drugs

BACKGROUND

Fentanyl test strips (FTS) are a harm reduction method for people to test their drugs for fentanyl. Ideal points for FTS distribution have not been identified. Many people who use drugs have frequent contact with the Emergency Department (ED). We piloted FTS distribution in two urban hospital EDs.

METHODS

Between June-December 2021 in Philadelphia, PA, patients with past 30-day drug use completed a survey about drug use, fentanyl attitudes, and FTS; then offered FTS and a brief training. Survey data were analyzed using SPSS for bivariate statistics.

RESULTS

Patients (n = 135) were primarily White (68.1%) and male (72.6%). Participants regularly interacted with substance use (57.8%) and benefits coordination (49.6%) services. The most common drugs used were heroin/fentanyl (68.9%), crack cocaine (45.2%) and cannabis (40.0%). Most (98.5%) had heard of fentanyl though few (18.5%) had ever used FTS. Across most drug types, participants were concerned about fentanyl. All accepted FTS training and distribution. Few (9.6%) were somewhat or very concerned about having FTS if stopped by police and this number varied by race (7.6% of White people were somewhat or very concerned, compared to 12.8% of Black people). Most participants were already engaged in risk reduction practices.

DISCUSSION

FTS are a widely desired harm reduction tool to facilitate informed decision-making, and non-harm reduction locations are potentially feasible and acceptable distribution sites. Given regular contact with EDs and social services across the sample, FTS should be offered at non-harm reduction locations that come into frequent contact with people who use drugs.

Contextual factors affecting the implementation of drug checking for harm reduction: a scoping literature review from a North American perspective

BACKGROUND

The opioid epidemic continues to be a significant cause of morbidity and mortality in the US. In 2020, 83% of opioid-related overdose deaths were due to synthetic opioids, such as fentanyl. Drug checking services have been widely implemented as a harm reduction intervention to facilitate the identification of substances in a drug sample. There is a need to inform decision-making on drug checking technologies and service implementation. This research aims to outline contextual considerations for the implementation of a drug checking service.

METHODS

A scoping review was conducted using a structured search strategy in PubMed and EMBASE. Articles were independently screened by two reviewers, and included if they were primary literature and reported on an actionable consideration(s) for drug checking services. Data elements were extracted using a standardized form, and included study design, study population, drug checking technology utilized or discussed, and main findings.

RESULTS

Twenty-nine articles were selected for inclusion, and four primary areas of consideration were identified: drug checking technologies, venue of a drug checking service, legality, and privacy. Technological considerations include the need for highly accurate, quantitative results which appeal to both populations of people with drug use disorder and recreational users. Accessibility of services was identified as an important factor that may be impacted by the location, integration with other services, how the service is provided (mobile vs. fixed), and the hours of operation. Maintaining plausible deniability and building trust were seen as important facilitators to service use and engagement. Issues surrounding legality were the most frequently cited barrier by patrons, including fear of criminalization, policing, and surveillance. Patrons and stakeholders identified a need for supportive policies that offer protections. Maintaining anonymity for patrons is crucial to addressing privacy-related barriers.

CONCLUSION

This review highlights the need to understand the local population and climate for drug checking to implement a drug checking service successfully. Common themes identified in the literature included considerations related to the choice of technology, the type of venue, and the impact of legality and privacy. We intend to utilize these considerations in future research to help guide discussions with US-based stakeholders.

Current attitudes toward drug checking services and a comparison of expected with actual drugs present in street drug samples collected from opioid users

BACKGROUND

The opioid epidemic continues to be associated with high numbers of fatalities in the USA and other countries, driven mainly by the inclusion of potent synthetic opioids in street drugs. Drug checking by means of various technologies is being increasingly implemented as a harm reduction strategy to inform users about constituent drugs in their street samples. We assessed how valued drug checking services (DCS) would be for opioid street drug users given the ubiquity of fentanyl and related analogs in the drug supply, the information they would most value from drug checking, and compared expected versus actual constituent drugs in collected samples.

METHODS

A convenience sample of opioid street drug users (N = 118) was recruited from two syringe service exchange programs in Chicago between 2021 and 2022. We administered brief surveys asking about overdose history, whether fentanyl was their preferred opioid, and interest in DCS. We also collected drug samples and asked participants what drug(s) they expected were in the sample. Provided samples were analyzed using LC-MS technology and the results compared to their expected drugs.

RESULTS

Participants reported an average of 4.4 lifetime overdoses (SD = 4.8, range = 0-20) and 1.1 (SD = 1.8, range = 0-10) past-year overdoses. A majority (92.1%) believed they had recently used drugs containing fentanyl whether intentionally or unintentionally. Opinions about the desirability of fentanyl were mixed with 56.1% indicating they did not and 38.0% indicating they did prefer fentanyl over other opioids, mainly heroin. Attitudes toward DCS indicated a general but not uniform receptiveness with a majority indicating interest in DCS though sizeable minorities believed DCS was "too much trouble" (25.2%) or there was "no point" in testing (35.4%). Participants were especially inaccurate identifying common cutting agents and potentiating drugs such as diphenhydramine in their samples (sensitivity = .17).

CONCLUSIONS

Results affirmed street drug users remain interested in using DCS to monitor their drugs and such services should be more widely available. Advanced checking technologies that provide information on the relative quantities and the different drugs present in a given sample available at point-of-care, would be most valuable but remain challenging to implement.

"I don't want to die": a qualitative study of coping strategies to prevent fentanyl-related overdose deaths among people who inject drugs and its implications for harm reduction policies

BACKGROUND

Fentanyl and fentanyl-related analogues are the main drivers of overdose death in the USA, particularly among people who inject drugs (PWID). Despite the fact that non-Hispanic whites exhibit higher population rates of synthetic opioid mortality, overdose deaths have increased among African American and Latinos in urban areas. Yet little attention has been paid to the introduction of fentanyl among rural PWID in Puerto Rico.

METHODS

We conducted N = 38 in-depth interviews with PWID in rural Puerto Rico to document participants' experiences of injection drug use after the arrival of fentanyl and the strategies they implemented to manage overdose death risks.

RESULTS

Participants suggest that the arrival of fentanyl in large scale happened after Hurricane Maria in 2017; this coincided with a dramatic increase in overdose episodes and deaths. Fear of overdose deaths motivated some participants to substitute intravenous drug use for other forms of substance use or to seek MOUD. PWID that continued injection use resorted to conducting "hit tests," avoiding injecting alone, using naloxone, and employing fentanyl testing strips.

CONCLUSIONS

While overdose deaths would have been higher without participants' willingness to adopt harm-reduction strategies, this paper illustrates the limits of these policies to address the current epidemic of fentanyl-related overdose deaths among this population. More studies are needed to understand how health disparities shape overdose risks for minority populations. However, major policy changes, in particular the revision of the harmful role of the War on Drugs and the termination of failed neoliberal economic policies that contribute to deaths of despair, should be addressed if we are to make a dent in this epidemic.

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.

A Dose of Truth: A Qualitative Assessment of Reactions to Messages about Fentanyl for People Who Use Drugs

Background: Fentanyl-related overdoses are occurring at alarming rates and developing campaigns to increase awareness about fentanyl and harm-reduction strategies is critical. A Dose of Truth is an educational campaign aiming to increase knowledge about the threat of fentanyl and risk of exposure among people who use drugs (PWUD). The current study tests preliminary concepts and messages for the campaign. Methods: Twenty-one one-on-one interviews were conducted with young adults ages 18-35 who use drugs. Participants discussed knowledge of fentanyl and perceived risk of exposure, and provided feedback on four concepts. Thematic analysis of transcripts generated insights about promising approaches and topics. Results: Findings demonstrated that fentanyl awareness is growing among PWUD, but they perceive low risk of exposure because they trust a source. Messaging that challenged that trust, by highlighting that contaminated drug supplies are increasingly widespread, made personal risk salient. Additionally, messaging conveyed through a personal narrative that encouraged carrying naloxone to protect friends was perceived as personally relevant. Conclusions: While opioid- and fentanyl-related campaigns exist, few have used an evidence-based process to guide campaign development. Addressing gaps in knowledge and developing messages that are personally relevant are foundational steps in creating effective campaigns on fentanyl and other substances.

Characteristics and context of fentanyl test strip use among syringe service clients in southern Wisconsin

BACKGROUND

Fentanyl adulteration of illicit drugs is a major driver of opioid-involved overdose in the USA. Fentanyl test strips are increasingly used by people who use drugs to check for fentanyl. However, little is known about factors that influence test strip use in this population.

METHODS

In this mixed-methods study employing semi-structured open-ended interviews (n = 29) and a structured survey (n = 341), we examined characteristics associated with test strip use, characteristics of test strip use, and situational, logistical and psychosocial factors influencing test strip use. Respondents were recruited from a syringe service program in southern Wisconsin. Bivariate tests of association and multivariable logistic regression examined the relationship between respondent characteristics and test strip use. Summary statistics were used to describe how situational, logistical and psychosocial factors impact test strip use.

RESULTS

Most respondents were male (59.6%), non-Hispanic white (77.4%), young (mean 35.7 years), reported heroin as their primary drug (70.7%), injection as their primary route (87.9%), and use ≥ 3 times daily (78.6%). In multivariable models, site, race and ethnicity, drug of choice, and seeking fentanyl were associated with test strip use. Among test strip users, 36.5% use them most of the time or more and 80.6% get positive results half the time or more. Among individuals reporting heroin, fentanyl, methamphetamine, or cocaine or crack cocaine at least once per month, 99.1%, 56.8%, 42.2%, and 55.7% reported testing these drugs, respectively. Test strip use is supported by information from suppliers, regular transportation, diverse distribution locations, recommendations from harm reduction staff, and having a safe or private place to use.

CONCLUSIONS

We found that individuals who use fentanyl test strips are more often non-Hispanic white, use heroin, and seek drugs with fentanyl relative to individuals without test strip use. Findings confirm high fentanyl penetration in the Wisconsin drug supply. Low rates of stimulant testing suggest inadequate awareness of fentanyl penetration. Findings support outreach to key populations, increased diversity of distributing locations, efforts to correct misperceptions about drug wasting, emphasis on pre-consumption testing, and the importance of adjunct behaviors to prevent overdose given high rates of intentional fentanyl use.

Pilot testing fentanyl test strip distribution in an emergency department setting: Experiences, lessons learned, and suggestions from staff

OBJECTIVES

Fentanyl test strips (FTSs) are increasingly used to address fentanyl contamination of the illicit drug supply by testing a drug for the presence of fentanyl, allowing people who use drugs (PWUD) to engage in overdose prevention. While emergency departments (EDs) have implemented various harm reduction strategies for PWUD, to date distribution of FTSs in EDs is limited and not evaluated. Thus, we sought to explore ED staff experiences distributing FTSs.

METHODS

Twenty-one staff serving different roles (e.g., physician, nurse, technician, social worker, certified recovery specialist) within two urban EDs in a major metropolitan area were enrolled in a pilot study to distribute FTS to patients who use drugs. Participants were interviewed about their experience at 3 weeks and again at 3 months. Interviews were recorded, transcribed verbatim, and coded using a conventional content analysis approach.

RESULTS

All participants endorsed the utility of FTS distribution in the ED. Across 42 interviews, participants discussed evolving strategies to approach patients about FTS, primarily favorable patient reactions to FTSs, improved dynamics between participants and patients, mixed intervention support from other staff, and named challenges of FTS distribution and recommendations to make FTS distribution in the ED widespread. Recommendations included medical records prompts to offer FTS, offering via different types of staff, and offering FTS during triage.

CONCLUSIONS

Implementing FTS distribution may improve patient rapport while providing patients with tools to avoid a fentanyl overdose. Participants generally reported positive experiences distributing FTSs within the ED but the barriers they identified limited opportunities to make distribution more integrated into their workflow. EDs considering this intervention should train staff on FTSs and how to identify and train patients and explore mechanisms to routinize distribution in the ED environment.

“It's my frenemy”: A qualitative exploration of knowledge and perceptions of fentanyl use during the COVID-19 pandemic in people who use drugs at a syringe services program in Philadelphia, PA

Background

Exacerbated by the COVID-19 pandemic and the proliferation of fentanyl and fentanyl analogs, overdose deaths have surged in the United States, making it important to understand how individuals who use drugs experience and perceive the risks of fentanyl use and how it has changed during the COVID-19 pandemic.

Methods

Twenty clients from a Philadelphia syringe services program completed a questionnaire and in-depth interview about their fentanyl experiences from January to March 2021. These interviews were transcribed and analyzed using thematic analysis methods.

Results

Sixty percent of participants were female and racial/ethnic minority. Participants indicated they believed fentanyl use accounted for most Philadelphia opioid-related overdoses and understood that fentanyl was different from other opioids. Fentanyl use was characterized as “all-consuming” by taking over lives and inescapable. While most perceived their risk of fentanyl overdose as high, there was low interest in and reported use of harm reduction strategies such as fentanyl test strips. The COVID-19 pandemic was noted to have negative effects on fentanyl availability, use and overdose risk, as well as mental health effects that increase drug use.

Conclusions

The divide between perceived risk and uptake of protective strategies could be driven by diminished self-efficacy as it relates to acting on and engaging with resources available at the syringe services program and represents a potential intervention target for harm reduction intervention uptake. But the COVID-19 pandemic has exacerbated risks due to fentanyl use, making an effective, accessible, and well-timed intervention important to address the disconnect between perceived overdose risk and use of preventive behaviors.

Perspectives of people in Philadelphia who use fentanyl/heroin adulterated with the animal tranquilizer xylazine; Making a case for xylazine test strips

Background

Xylazine is an animal tranquilizer increasingly detected in those who have died of an opioid overdose in Philadelphia, PA and elsewhere. Despite an increasing presence of xylazine in the local fentanyl/heroin drug market and its association with ulcers, there are few perspectives about xylazine from people who use drugs and no data about the utility of a hypothetical xylazine test strip.

Methods

Between January to May 2021 in Philadelphia, PA, people who used fentanyl/heroin and had previously used fentanyl test strips were queried about xylazine and hypothetical xylazine test strips. Interviews were transcribed and analysis was conducted via conventional content analysis.

Results

Participants (7 spontaneously, 6 after probing, n = 13) discussed "tranq" (i.e., xylazine) in the fentanyl/heroin supply. None enjoyed tranq or wanted it in their fentanyl/heroin. Participants suspected xylazine saturation of the fentanyl/heroin market, disliked the sensation of the drug, and had safety concerns about xylazine exposure. Participants did not indicate concerns about overdose. All were interested in hypothetical xylazine test strips. While previous literature indicates that some people enjoy tranq in their fentanyl/heroin, our findings differed, with participants expressing concern about the consequences of undesired exposure.
