RESUMO
Drug consumption is driven by a drug's pharmacological effects, which are experienced as rewarding, and is influenced by genetic, developmental, and psychosocial factors that mediate drug accessibility, norms, and social support systems or lack thereof. The reinforcing effects of drugs mostly depend on dopamine signaling in the nucleus accumbens, and chronic drug exposure triggers glutamatergic-mediated neuroadaptations in dopamine striato-thalamo-cortical (predominantly in prefrontal cortical regions including orbitofrontal cortex and anterior cingulate cortex) and limbic pathways (amygdala and hippocampus) that, in vulnerable individuals, can result in addiction. In parallel, changes in the extended amygdala result in negative emotional states that perpetuate drug taking as an attempt to temporarily alleviate them. Counterintuitively, in the addicted person, the actual drug consumption is associated with an attenuated dopamine increase in brain reward regions, which might contribute to drug-taking behavior to compensate for the difference between the magnitude of the expected reward triggered by the conditioning to drug cues and the actual experience of it. Combined, these effects result in an enhanced motivation to "seek the drug" (energized by dopamine increases triggered by drug cues) and an impaired prefrontal top-down self-regulation that favors compulsive drug-taking against the backdrop of negative emotionality and an enhanced interoceptive awareness of "drug hunger." Treatment interventions intended to reverse these neuroadaptations show promise as therapeutic approaches for addiction.

BACKGROUND: Primary care is an important yet underutilized resource in addressing the overdose crisis. Previous studies have identified important aspects of primary care for people who use drugs (PWUD) and have found patient involvement in healthcare decisions and goal-setting to be especially critical. However, there has been limited research describing the primary care goals of PWUD. In harm reduction settings, where it is imperative that PWUD set their own goals, this research gap becomes especially relevant. OBJECTIVE: To explore how PWUD navigate primary care with a focus on understanding their primary care goals. DESIGN: A qualitative study using semi-structured interviews. PARTICIPANTS: PWUD currently engaged in primary care at the Respectful and Equitable Access to Comprehensive Healthcare (REACH) Program, a harm reduction-based primary care program in New York City. APPROACH: Between June 2022 and August 2022, we conducted 17 semi-structured interviews. Informed by phenomenology, transcripts were coded using both inductive and deductive codes and themes were developed using thematic analysis approaches. KEY RESULTS: Phenomenological analysis identified four core components that, together, created an experience that participants described as "a partnership" between patient and provider: (1) patient-provider collaboration around patient-defined healthcare goals; (2) support provided by harm reduction-based approaches to primary care anchored in incrementalism and flexibility; (3) care teams' ability to address healthcare system fragmentation; and (4) the creation of social connections through primary care. This holistic partnership fostered positive primary care experiences and supported participants' self-defined care goals, thereby facilitating meaningful care outcomes. CONCLUSIONS: To best meet the primary care goals of PWUD, these findings underscore the importance of primary care providers and programs facilitating such partnerships through organizational-level support anchored in harm reduction. Future research should explore how these experiences in primary care affect patient health outcomes, ultimately shaping best practices in the provision of high-quality primary care for PWUD.

Among people living with HIV (PLWH), heavy alcohol use is associated with many negative health consequences. However, the impacts of heavy alcohol use are not well described for PLWH who use drugs. Thus, we investigated the prevalence and correlates of heavy alcohol use among a cohort of people who use drugs (PWUD) living with HIV in Vancouver, Canada. We accessed data from an ongoing community-recruited prospective cohort of PLWH who use drugs with linked comprehensive HIV clinical monitoring data. We used generalized linear mixed-effects modeling to identify factors longitudinally associated with periods of heavy alcohol use between December 2005 and December 2019. Of the 896 participants included, 291 (32.5%) reported at least one period with heavy alcohol use. Periods of recent incarceration (Adjusted Odds Ratio [AOR] = 1.48, 95% Confidence Interval [CI]: 1.01-2.17), encounters with police (AOR = 1.87, 95% CI: 1.37-2.56), and older age (AOR = 1.05, 95% CI: 1.02-1.07) were positively associated with heavy alcohol use. Engagement in drug or alcohol treatment (AOR = 0.54, 95% CI: 0.42-0.70) and male gender (AOR = 0.46; 95% CI: 0.27-0.78) were negatively associated with heavy alcohol use. We observed that heavy alcohol use was clearly linked to involvement with the criminal justice system. These findings, together with the protective effects of substance use treatment, suggest the need to expand access for drug and alcohol treatment programs overall, and in particular through the criminal justice system to reduce alcohol-related harms among PLWH who use drugs.

Socioeconomic factors are important correlates of drug use behaviors and health-related outcomes in people who use drugs (PWUD) residing in urban areas. However, less is known about the complex overlapping nature of socioeconomic conditions and their association with a range of individual, drug use, and health-related factors in men and women who use drugs. Data were obtained from two community-recruited prospective cohorts of PWUD. Using a gender-stratified approach, we conducted repeated measures latent class analyses (RMLCA) to identify discrete latent socioeconomic subgroups. Multivariable generalized estimating equations were then used to identify correlates of class membership. Between June 2014 and December 2018, RMLCA of 9844 observations from 1654 participants revealed five distinct patterns of socioeconomic status for both men and women. These patterns were primarily distinguished by variations in income, material and housing security, income generation activity, exposure to violence, criminal justice involvement, and police contact. Across gender, progressive increases in exposure to multiple dimensions of socioeconomic disadvantage were found to be associated with frequent use of opioids and stimulants, accessing social services, and being hepatitis C virus antibody-positive. Similar but less congruent trends across gender were observed for age, binge drug use, engagement with opioid agonist therapy, and living with HIV. Gendered patterns of multiple and overlapping dimensions of socioeconomic adversity aligned with patterns of frequent drug use and health-related concerns, highlighting priority areas for gender-inclusive, multilevel responses to mitigate health disparities and meet the diverse socioeconomic needs of urban-dwelling men and women who use drugs.

BACKGROUND: Policies to address substance use differ greatly between settings, where goals may range from zero-tolerance to harm reduction. Different approaches impact formats of care, policing, and even interpersonal interactions, and may play a role in the labelling and stigmatization of people who use drugs (PWUD). Where Sweden has a more restrictive policy, aiming to have a society free from drugs, Denmark has embraced harm reduction principles. The aim of this study was to explore PWUDs' experiences of interpersonal interactions, policing, and service formats in the two countries. METHODS: The data consists of 17 qualitative semi-structured interviews with Swedish PWUD who have been in both Sweden and Denmark. Recruitment took place at harm reduction sites in both countries, and through snowball sampling. RESULTS: Participants reflected on how they were perceived by those in public spaces, and received by care systems and personnel. In public settings in Sweden, participants felt they were ignored, rendered invisible, and lost their humanity. In Denmark, they were perceived and acknowledged, valued as people. This was simultaneously linked to being embodied by the availability of differing service offerings and policing practices, which solidified their "right to be out" in public. Reflecting on their reception in the treatment system, strict formatting in Sweden caused participants to feel that an identity was projected upon them, limiting their opportunities or growth of new facets of identity. Care relations in Denmark fostered more opportunity for autonomy and trust. CONCLUSION: A zero-tolerance policy and associated public discourses could solidify and universalize stigmatizing categorizations as a central feature of PWUD identity and reception from those around them, exacerbating social exclusion. Conversely, harm reduction-centered policies fostered positive interactions between individuals with care providers, public, and police, which may promote inclusion, empowerment, and wellbeing.

BACKGROUND: Efforts to distribute naloxone have equipped more people with the ability to reverse opioid overdoses but people who use drugs are often reluctant to call 911 due to concerns for legal repercussions. Rural communities face unique challenges in reducing overdose deaths compared to urban communities, including limited access to harm reduction services as well as greater concerns about stigma and privacy. METHODS: The Rural Opioid Initiative was funded in 2017 to better understand the health-related harms associated with the opioid crisis in rural US communities and consists of eight studies spanning ten states and 65 counties. Each study conducted semi-structured qualitative interviews with people who use drugs to understand contextual factors influencing drug use and health behaviors. We analyzed qualitative data from seven studies with data available at the time of analysis to understand peer response to overdose. RESULTS: Of the 304 participants interviewed, 55% were men, 70% were white, 80% reported current injection drug use, and 60% reported methamphetamine use. Similar to what has been found in studies focused on urban settings, people who use drugs in rural communities use a range of strategies to reverse overdoses, including non-evidence-based approaches. Several reported that multiple doses of naloxone are needed to reverse overdose. Three themes emerged around the willingness to call 911, including (1) hesitancy to call 911 for fear of legal consequences, (2) negative perceptions or experiences with law enforcement officers, and (3) efforts to obtain medical intervention while avoiding identification/law enforcement involvement. CONCLUSION: People who use drugs employ multiple strategies to attempt overdose reversal, including non-evidence-based approaches. Greater education about the most effective and least harmful strategies is needed. Reluctance to call 911 is rooted in concerns about potential legal consequences as well as perceptions about law enforcement officers, which may be heightened in rural communities where people who use drugs are more easily identified by law enforcement. People who use drugs will go to great strides to connect their peers to needed medical services, suggesting that comprehensive interventions to reduce interactions with law enforcement officers and eliminate legal consequences for reporting overdoses are critical.

BACKGROUND: Deaths due to drug overdose are an international issue, causing an estimated 128,000 global deaths in 2019. Scotland has the highest rate of drug-related deaths in Europe, with those in the most deprived areas at greater risk than those in affluent areas. There is a paucity of research on digital solutions, particularly from the perspective of those who use drugs who additionally access harm reduction and homelessness support services. The Digital Lifelines Scotland programme (DLS) provides vulnerable people who use/d drugs with digital devices to connect with services. METHODS: This paper reports on the evaluation of the DLS from the perspective of service users who accessed services for those at risk of drug-related harms. A mixed methods approach was used including an online-survey (n = 19) and semi-structured interviews (n = 21). Survey data were analysed descriptively and interview data through inductive coding, informed by the Technology, People, Organisations and Macroenvironmental factors (TPOM) framework, to investigate the use, access, and availability of devices, and people's experiences and perceptions of them. RESULTS: Most participants lived in social/council housing (63.2%, n = 12), many lived alone (68.4%, n = 13). They were mainly over 40 years old and lived in a city. Participants described a desire for data privacy, knowledge, and education, and placed a nascent social and personal value on digital devices. Participants pointed to the person-centred individuality of the service provision as one of the reasons to routinely engage with services. Service users experienced an increased sense of value and there was a palpable sense of community, connection and belonging developed through the programme, including interaction with services and devices. CONCLUSIONS: This paper presents a unique perspective which documents the experiences of service users on the DLS. Participants illustrated a desire for life improvement and a collective and individual feeling of responsibility towards themselves and digital devices. Digital inclusion has the potential to provide avenues by which service users can safely and constructively access services and society to improve outcomes. This paper provides a foundation to further cultivate the insight of service users on digital solutions in this emerging area.

BACKGROUND: Globally, non-fatal overdose (NFOD) rates consequent to drug use, typically opioids, continue increasing at a startling rate. Existing quantitative research has revealed myriad factors and characteristics linked to experiencing NFOD, but it is critically important to explore the lived context underlying these associations. In this qualitative study, we sought to understand the experiences of NFOD among people who use drugs in a Scottish region in order to: enhance public policy responses; inform potential intervention development to mitigate risk; and contribute to the literature documenting the lived experience of NFOD. METHODS: From June to July 2021, two peer researchers conducted face-to-face semi-structured interviews with people who use drugs who had experienced recent NFOD attending harm reduction services in Tayside, Scotland. These were transcribed verbatim and evaluated using thematic analysis with an inductive approach which had an experiential and essentialist orientation. RESULTS: Twenty people were interviewed across two sites. Of those, 15 (75%) were male and mean age was 38.2 (7.7) years. All had experienced at least one NFOD in the prior six months, and all reported polydrug use. Five themes were identified, within which 12 subthemes were situated. The themes were: social context; personal risk-taking triggers; planned and impulsive consumption; risk perception; and overdose reversal. The results spoke to the environmental, behavioural, cognitive, economic, and marketplace, factors which influence the context of NFOD in the region. CONCLUSIONS: A complex interplay of behavioural, psychological, and situational factors were found to impact the likelihood of experiencing NFOD. Structural inequities which policy professionals and civic leaders should seek to remedy were identified, while service providers may seek to reconfigure healthcare provision for people who use drugs to account for the interpersonal, psychological, and social factors identified, which appear to precipitate NFOD. TRIAL REGISTRATION: Not applicable.

People who inject drugs (PWID) are at an increased risk of multimorbid mental health and chronic diseases, which are frequently underdiagnosed and under-treated due to systemic barriers and ongoing substance use. Healthcare engagement is essential to address these conditions and prevent excess morbidity and mortality. The goal of this study was to understand how PWID engage in care for their chronic health conditions and substance use treatment given the known historic and pervasive barriers. We conducted 24 semistructured qualitative interviews informed by the Behavioral Model for Vulnerable Populations between July-September 2019. Participants were sampled across a range of comorbidities, including co-occurring mental health disorders. Thematic analysis was conducted to explore experiences of healthcare engagement for multimorbid chronic diseases, mental health, and treatment for substance use disorder. Mean age for participants was 58 years; 63% reported male sex and 83% reported Black race. Interviews yielded themes regarding healthcare access and wraparound services, positive patient-provider relationships, service integration for substance use treatment and mental health, healthcare needs alignment, medication of opioid use disorder stigma, and acceptance of healthcare. Taken together, participants described how these themes enabled healthcare engagement. Engagement in care is crucial to support health and recovery. Clinical implications include the importance of strengthening patient-provider relationships, encouraging integration of medical and mental health services, and counseling on substance use treatment options in a non- stigmatizing manner. Additionally, policy to reimburse wrap-around support for substance use recovery can improve care engagement and outcomes related to chronic diseases, mental health, and substance use among PWID. No Patient or Public Contribution: While we acknowledge and thank ALIVE participants for their time for data collection and sharing their perspectives, no ALIVE participants, other people who use drugs, and service users were involved in data collection, analysis or interpretation of data, or in preparation of the manuscript.

Background: Injection risk behavior is a major predictor of HIV infection. The present study was conducted to survey the effect of educational intervention based on the theory of planned behavior on changing high-risk behaviors (the high-risk behaviors of injecting and behaviors of transmitting blood diseases to others) of injecting drug users under the coverage of addiction harm reduction centers. Methods: This study is an experimental research on 120 drug addicts in 2021-2022. Two addiction harm reduction centers in Fasa City, Iran, were chosen randomly (one as the test group and the other as the control group). The data collection tool is made up of two parts. The first part is a questionnaire on demographics. The second part is a questionnaire based on the theory of planned behavior, which was made using information from different sources and studies. The training program was set up based on the pretest results and the theory of planned behavior for the test group. Before and six months after the educational intervention, the experimental and control groups filled out the questionnaire. With a significance level of 0.05, the independent t, chi-square, and paired t statistical tests were used to examine the data using the SPSS 22 program. Results: In the test group, the average age of addicts was 37.42 ± 10.55 years, while in the control group, the average age was 38.36 ± 10.09 years (p=0.244). Six months after the educational intervention, all TPB theory's constructs (knowledge, attitude, subjective norms and perceived behavioral control, behavioral intention, and behavior of injecting drug users) were higher in the test group than in the control group (p=0.001). Conclusion: The results show the effect of this educational intervention in reducing high-risk behaviors related to injection in injection drug addicts, so it is suggested as a useful method to reduce high-risk injection behaviors in these people.

In Senegal, violent delinquency and illicit drug use are on the increase. This study focuses on two distinct groups: drug users (DUs) undergoing rehabilitation and violent ex-offenders (VEs). The methodology adopted includes a quantitative survey of the general population (n=1009), followed by a qualitative survey of fifteen participants, including eight DUs undergoing treatment at the Centre de prise en charge intégrée des addictions de Dakar (CEPIAD) (Integrated Addictions Management Center of Dakar) and the Centre Jacques Chirac de Thiaroye, and seven former VEs from the Grand Yoff district. This neighborhood, known for its violence, is juxtaposed with the Grand Yoff social housing estate, a residential area also affected by outbreaks of violence. This study aims to establish the link(s) between drug use and criminal violence by analyzing the life stories of young adults who have managed to leave drug use and delinquency behind. It then looks to identify the determinants of resilience in certain young people. The study revealed delinquent violence among young people does not systematically result from drug use. Rather, drug use is a factor conducive to violence. The links between drugs and violence depend on individual predisposition, the type of drugs used, and the level of addiction. Resilience results from a web of individual, sociocultural, and environmental factors. It is not static, but rather the result of a series of successes, failures, and even relapses.

INTRODUCTION: The HIV Prevention Trials Network (HPTN) 074 study demonstrated a positive effect of an integrated systems navigation and psychosocial counseling intervention on HIV treatment initiation, viral suppression, medication assisted treatment (MAT) enrollment, and risk of death among people who inject drugs (PWID). In this sub-study, we analyzed the incidence, causes, and predictors of death among HIV-infected and uninfected participants. METHODS: The HPTN 074 randomized clinical trial was conducted in Indonesia, Ukraine, and Vietnam. HIV-infected PWID with unsuppressed viral load (indexes) were recruited together with at least one of their HIV-negative injection partners. Indexes were randomized in a 1:3 ratio to the intervention or standard of care. RESULTS: The trial enrolled 502 index and 806 partner participants. Overall, 13% (66/502) of indexes and 3% (19/806) of partners died during follow-up (crude mortality rates 10.4 [95% CI 8.1-13.3] and 2.1 [1.3-3.3], respectively). These mortality rates were for indexes nearly 30 times and for partners 6 times higher than expected in a population of the same country, age, and gender (standardized mortality ratios 30.7 [23.7-39.0] and 5.8 [3.5-9.1], respectively). HIV-related causes, including a recent CD4 < 200 cells/µL, accounted for 50% of deaths among indexes. Among partners, medical conditions were the most common cause of death (47%). In the multivariable Cox model, the mortality among indexes was associated with sex (male versus female aHR = 4.2 [1.5-17.9]), CD4 count (≥ 200 versus < 200 cells/µL aHR = 0.3 [0.2-0.5]), depression (moderate-to-severe versus no/mild aHR = 2.6 [1.2-5.0]) and study arm (intervention versus control aHR = 0.4 [0.2-0.9]). Among partners, the study arm of the index remained the only significant predictor (intervention versus control aHR = 0.2 [0.0-0.9]) while controlling for the effect of MAT (never versus ever receiving MAT aHR = 2.4 [0.9-7.4]). CONCLUSIONS: The results confirm that both HIV-infected and uninfected PWID remain at a starkly elevated risk of death compared to general population. Mortality related to HIV and other causes can be significantly reduced by scaling-up ART and MAT. Access to these life-saving treatments can be effectively improved by flexible integrated interventions, such as the one developed and tested in HPTN 074.

BACKGROUND: People who inject drugs (PWID) are a key population for the prevention and care of HIV infection. METHODS: This scoping review covers recent (post-2010) systematic reviews on engagement of PWID in sequential stages of HIV care from uptake, to achieving viral suppression, and to avoiding AIDS-related mortality. RESULTS: We found that data on engagement of PWID into antiretroviral therapy (ART) were particularly scarce, but generally indicated very low engagement in ART. Studies of adherence and achieving viral suppression showed varying results, with PWID sometimes doing as well as other patient groups. The severity of social, medical and psychiatric disability in this population poses significant treatment challenges and leads to a marked gap in AIDS mortality between PWID and other population groups. CONCLUSIONS: Given the multi-level barriers, it will be difficult to reach current targets (UNAIDS fast-track targets of 95-95-95) for ART for PWID in many locations. We suggest giving priority to reducing the likelihood that HIV seropositive PWID will transmit HIV to others and reducing morbidity and mortality from HIV infection and from other comorbidities.

BACKGROUND: In this qualitative analysis we aimed to explore addiction physicians' perspectives on safer injection education for people who inject drugs, especially: (1) on possible means of introducing safer injection education in the medical environment, (2) on the compatibility of safer injection education with each physician's core values and goals, and (3) on possible reasons for the ethical dilemma in safer injection education. METHODS: We conducted semi-structured interviews with eleven physicians practicing addiction medicine in France in clinical and harm reduction settings. RESULTS: All participants were in favor of educational interventions for people who inject drugs. Nonetheless, these interventions varied from simple advice to injection supervision and they were seen as less acceptable when they concerned the practical and material aspects of injection. Some participants found that physicians practicing in clinical settings, where patients consult mostly to stop their drug use, should not practice safer injection education. On the contrary, other participants claimed that safer injection education was essential in all settings and was not a choice but rather a duty for addiction physicians. The ethical dilemma of such intervention when delivered by medical staff was viewed as a complex phenomenon, related to the representations of intravenous drug use and to societal expectations from physicians. CONCLUSION: Physicians' views on safer injection education for people who inject drugs reveal an emotionally charged subject related to the structural organization of addiction management in France. Such education is marked by an arduous history of harm reduction policies in France. IRB REGISTRATION: #00011928.

Background: Prospective memory and response inhibition are interrelated constructs, though studied separately in the drug addiction literature. Also, although sustained attention underlies response inhibition, its role in the relation between these functions has been largely neglected. The limited research on the cognitive effects of methadone-maintenance treatment (MMT) further stresses the importance of investigating these effects. Objective: Therefore, the current study focused on possible effects of MMT combined with long-term drug abuse on all these functions. Thirty five long term opiate/poly-substance users in MMT and thirty four drug-free controls were screened for socioeconomic status, anxiety, depression and general, non-verbal intelligence and then tested on a self-report measure of prospective memory and on the Go/No-Go task. Results: Compared to controls, the MMT group scored worse in all functions assessed. Prospective memory scores were also negatively related to Go/NoGo accuracy scores. Conclusion: As predicted, (a) the MMT participants show impairments in prospective memory, sustained attention and response inhibition and (b) prospective memory, response inhibition and sustained attention are related constructs. The results of this study could inform current rehabilitation and relapse prevention cognitive training practices.

Drug injection represents a major health problem in the US, with severe health consequences including the transmission of blood-borne infections. An examination of the most recent trends in drug injection is warranted by the fast-evolving drug epidemic and recent policy changes such as the federal funding ban on needle exchange programs. This research examines current drug injection trends, patterns, and socioeconomic and behavioral profiles of people who inject drugs (PWID). Data were derived from the 2002 to 2019 National Survey on Drug Use and Health (NSDUH). After examining the annual prevalence of drug injection since 2002, a latent class analysis was conducted to identify drug injection and other substance misuse patterns among PWID using the latest (2015-2019) NSDUH datasets. Associations between class membership and behavioral health comorbidities and treatment receipt were also assessed. The drug injection prevalence among US adults aged 18-64 increased from 0.21% in 2002/2004 to 0.36% in 2017/2019. Three distinctive groups were identified: the heroin injection group (45.2%), the methamphetamine injection group (28.0%), and the multi-drug injection group (26.8%). The methamphetamine injection group reported greater risks of experiencing serious psychological distress, suicidality, and limited substance use treatment. Special attention is needed for those who primarily injected methamphetamine. Programs to promote harm reduction and increase access to addiction treatment need to be expanded in at-risk communities while accounting for their distinct socioeconomic and drug use/misuse profiles.

INTRODUCTION: People who use, including those who inject, drugs in Indonesia are disproportionately affected by HIV, but tend to be diagnosed at a late stage of infection, delay initiation to and have poor rates of retention in antiretroviral treatment, resulting in high rates of morbidity and mortality. In addition to legal, policy and health system barriers, PWID may be hesitant to engage in HIV, treatment and care due to lack of knowledge, distrust of the health care system, and stigma related to their dual drug use and HIV status. Implementation of formal peer support initiatives may reduce provider- and individual-level barriers and increase testing, linkage to, and engagement in HIV care among people who use drugs. METHODS: We conducted a community-led qualitative study to explore the impacts of peer support for people who inject drugs on HIV care access and engagement in Indonesia. Semi-structured, in-depth interviews were conducted with 20 participants in Jakarta and Bandung. Thematic analysis was used to explore how people who inject drugs living with HIV (PWID LHIV) (n = 8), peer support workers (n = 6), and service providers (n = 6) perceived peer support provision by non-governmental organisations. RESULTS: Participants unanimously described peer support as beneficial. Peer support workers were widely credited with facilitating access to HIV testing, referral to care, uptake of and adherence to antiretroviral treatment, as well as sustaining engagement in care for PWID. Support mechanisms that facilitated positive peer experiences included provision of HIV knowledge and awareness, emotional support, help with navigating complex bureaucracy, developing trust in health care services, enhancing confidence and motivation, and supporting peers to navigate a wide range of health and social welfare services beyond HIV-related care. CONCLUSIONS: Findings indicate that peer support can enhance access to testing, linkage to, and engagement in HIV care for people who use drugs living with HIV in Indonesia. In a context of an ongoing HIV epidemic among people who use drugs, reduced funding and policy attention to HIV and harm reduction, there is an urgent need to prioritize peer support interventions to identify people who use drugs facing health risks and link them to appropriate services.

Self-management programs improve health outcomes and self-management is recommended for chronic conditions. Yet chronic disease self-management supports have rarely been applied to people who use drugs (PWUD). Thus, our objective was to explore self-management experiences among marginalized PWUD. We used community-based participatory methods and conducted qualitative interviews. Participants self-identified as having long-term and past year experience using non-prescribed drugs, one other chronic condition, and socioeconomic marginalization. We analyzed the data using reflexive thematic analysis. Although many participants considered drug use a chronic health issue, self-medicating with non-prescribed drugs was also a key self-management strategy to address other health issues. Participants also described numerous other strategies, including cognitive and behavioral tactics. These findings highlight the need for a safe supply of pharmaceutical-grade drugs to support self-management among marginalized PWUD. Self-management supports should also be tailored to address relevant topics (e.g., harm reduction, withdrawal), include creative activities, and not hinder PWUD's agency.

In the United States, 10% of HIV infections diagnosed in 2018 were attributed to unsafe injection drug use or male-to-male sexual contact among persons who inject drugs (PWID) (1). In 2017, among PWID or men who have sex with men and who inject drugs (MSM-ID), 76% of those who received a diagnosis of HIV infection lived in urban areas* (2). To monitor the prevalence of HIV infection and associated behaviors among persons who reported injecting drugs in the past 12 months, including MSM-ID, CDC's National HIV Behavioral Surveillance (NHBS) conducts interviews and HIV testing among populations of persons at high risk for HIV infection (MSM, PWID, and heterosexually active adults at increased risk for HIV infection) in selected metropolitan statistical areas (MSAs) (3). The estimated HIV infection prevalence among PWID in 23 MSAs surveyed in 2018 was 7%. Among HIV-negative PWID, an estimated 26% receptively shared syringes and 68% had condomless vaginal sex during the preceding 12 months. During the same period, 57% had been tested for HIV infection, and 55% received syringes from a syringe services program (SSP). While overall SSP use did not significantly change since 2015, a substantial decrease in SSP use occurred among Black PWID, and HIV prevalence among Black PWID was higher than that among Hispanic and White PWID. These findings underscore the importance of continuing and expanding HIV prevention programs and community-based strategies for PWID, such as those provided by SSPs, especially following service disruptions created by the COVID-19 pandemic (4). Efforts are needed to ensure that PWID have low-barrier access to comprehensive and integrated needs-based SSPs (where legally permissible) that include provision of sterile syringes and safe syringe disposal, HIV and hepatitis C virus (HCV) testing and referrals to HIV and HCV treatment, HIV preexposure prophylaxis, and treatment for substance use and mental health disorders.

BACKGROUND: Methadone therapy clinics have been recently introduced in Tanzania, aiming at reducing risk behaviors and infection rates of viral hepatitis and HIV among people who use drugs. The objective of this study was to estimate the prevalence, associated factors and knowledge level of these conditions among people who use drugs attending a methadone clinic in Tanzania. METHODS: We enrolled 253 People who using drugs receiving Methadone therapy. Clinical data was retrospectively collected from the medical records and face-to face interviews were conducted to determine the behavioral risk factors and respondents' knowledge on viral hepatitis and HIV. RESULTS: An overall seroprevalence of viral hepatitis (either hepatitis B surface antigen or anti-hepatitis C virus) was 6.3%, while that of hepatitis B virus mono infection was 3.5% and anti-hepatitis C antibodies was 3.5%. Seroprevalence of HIV was 12.6%. Viral hepatitis was strongly predicted by advanced age (> 35 years) (p = 0.02) and staying at Kirumba area (p = 0.004), and HIV infection was predicted by increased age (> 37 years) (p = 0.04) and female sex (p < 0.001). Regarding the knowledge of viral hepatitis, majority of the respondents were unaware of the transmission methods and availability of hepatitis B virus vaccines and only 17% were classified as well informed (provided ≥4 correct answers out of 7 questions). Good knowledge was highly predicted by higher education level of the individual (p = 0.001). CONCLUSIONS: Despite the efforts to curb viral hepatitis and HIV infections through Methadone clinics, infection rates among people who use drugs are still high and the general knowledge on preventive measures is inadequate.
