Abstract
BACKGROUND Although the sale of nonprescription syringes in pharmacies is legal in most states, people who inject drugs (PWID) continue to face obstacles to syringe purchase like stigma, prohibitive costs, restrictive policies, and stocking issues. We examined the consistency of syringe pricing as another possible barrier. METHODS We analyzed data on syringe prices and other relevant variables from 153 unique secret shopper visits to 2 retail chain pharmacies in Massachusetts (MA), New Hampshire (NH), Oregon (OR), and Washington (WA) as part of the fidelity component of a large pharmacy-focused intervention study. Pretax prices from purchases made between August 2019 and May 2021 were adjusted for inflation to 2022 dollars, and a linear regression of the price of a 10-pack of syringes was constructed to examine the determinants of syringe pricing. RESULTS The average real price of a 10-pack of syringes across all states was $4.53 (SD = 0.99), with wide variability between pharmacies (max = $11.44, min = $1.70) and between states (mean OR = $5.76, WA = $4.74, MA = $4.33, NH = $4.30). Forty-seven percent (n = 72) of the purchases were taxed despite syringes being tax exempt in MA and WA, and not having a sales tax in NH or OR. The results of the regression suggest that certain needle gauges were associated with lower overall prices, while 1 pharmacy chain and 2 syringe brands were associated with higher overall prices. CONCLUSIONS The high variability in syringe pricing presents another barrier to pharmacy-based syringe access since high prices may leave PWID no choice but to reuse or share needles, especially in areas with limited alternatives or without a syringe service program. Leadership from healthcare systems, pharmacy chains, and state and local policymakers is essential to reduce stigma and to implement policies that streamline syringe purchases, eliminate the taxation of exempt syringes in accordance with state laws, and reduce the variation in syringe prices.

Abstract
Objectives Fentanyl is a highly potent opioid and has, until recently, been considered an unwanted contaminant in the street drug supply among people who use drugs (PWUD). However, it has become a drug of choice for an increasing number of individuals. This systematic review evaluated intentional non-medical fentanyl use among PWUD, specifically by summarizing demographic variance, reasons for use, and resulting patterns of use. Methods The search strategy was developed with a combination of free text keywords and MeSH and non-MeSH keywords, and adapted with database-specific filters to Ovid MEDLINE, Embase, Web of Science, and PsychINFO. Studies included were human studies with intentional use of non-medical fentanyl or analogues in individuals older than 13. Only peer-reviewed original articles available in English were included. Results The search resulted in 4437 studies after de-duplication, of which 132 were selected for full-text review. Out of 41 papers included, it was found that individuals who use fentanyl intentionally were more likely to be young, male, and White. They were also more likely to have experienced overdoses, and report injection drug use. There is evidence that fentanyl seeking behaviours are motivated by greater potency, delay of withdrawal, lower cost, and greater availability. Conclusions Among PWUD, individuals who intentionally use fentanyl have severe substance use patterns, precarious living situations, and extensive overdose history. In response to the increasing number of individuals who use fentanyl, alternative treatment approaches need to be developed for more effective management of withdrawal and opioid use disorder.

Trends in self-reported non-fatal overdose and patterns of substance use before and during the COVID-19 pandemic in a prospective cohort of adults who have injected drugs - Baltimore, Maryland, 2014-2022. Drug Alcohol Depend 2023; 251:110954. [PMID: 37716287 PMCID: PMC10538370 DOI: 10.1016/j.drugalcdep.2023.110954] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Revised: 07/25/2023] [Accepted: 08/26/2023] [Indexed: 09/18/2023]
Abstract
BACKGROUND Overdose deaths increased during the COVID-19 pandemic in the United States. Less is known about drug use behavior changes during the same time period. We examined differences in non-fatal overdose and drug use behaviors before and after the start of the COVID-19 pandemic in a community-recruited cohort of adults who have injected drugs. METHODS 721 participants attended 7401 visits between Jan 2014 and Mar 2022. Outcomes (non-fatal overdose, drug route of administration, type of drugs used) were assessed via self-report in the last six months. We compared pre-pandemic (Jan 2014-Mar 2020) to inter-pandemic (Dec 2020-Mar 2022) prevalence of each outcome using Cohcrane-Maentel-Haeszel odds ratios (CMH-OR). We then estimated probabilities for transitioning between specific behaviors from participants' last pre-pandemic visit to their first inter-pandemic visit. RESULTS Comparing pre-pandemic visits to inter-pandemic visits, the prevalence of non-fatal overdose did not change (CMH-OR 1.06, 95% CI 0.75-1.50); the prevalence of injection (CMH-OR 0.13, 95% CI 0.1-0.17) and non-injection (CMH-OR 0.51, 95% CI 0.42-0.61) drug use declined. More than a third (35.7%) of persons using both injection and non-injection drugs pre-pandemic transitioned to exclusive non-injection use during the pandemic. By contrast, few (4.0%) persons using non-injection drugs exclusively pre-pandemic transitioned to injecting during the pandemic. CONCLUSION Among adults who have injected drugs, the start of the COVID-19 pandemic was associated with a reduced drug use prevalence and transitions from injection to non-injection use. Average overdose prevalence was unchanged, but these behavior changes may have helped mitigate overdose harm.

THE INTERNATIONAL JOURNAL OF DRUG POLICY 2023:104150. [PMID: 37541925 DOI: 10.1016/j.drugpo.2023.104150] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Revised: 07/17/2023] [Accepted: 07/25/2023] [Indexed: 08/06/2023]
Abstract
BACKGROUND Polysubstance use is associated with negative health and social outcomes among people who inject drugs. We aimed to describe trends in polysubstance use and identify psychosocial correlates and associated drug use risk behaviours. We defined polysubstance use as intentional same day use of more than one of three drug classes: opioids, other non-opioid depressants (hereafter 'depressants'), and stimulants. METHODS We used 10 years (2012-2022, excluding 2020) of data from annual surveys in Australian capital cities with people who inject drugs (N=5657) to construct five mutually exclusive polysubstance use profiles: opioid-depressant, opioid-stimulant, stimulant-depressant, opioid-stimulant-depressant, and single drug class use. We examined time trends using the Mann Kendall test and identified correlates using multinomial logistic regression. RESULTS Same day polysubstance use was relatively common among this sample (43.6%). Opioid-depressant use was the most frequent polysubstance use profile, but this decreased over the study period (32.6% to 13.3%, p<0.001). This aligned with observed decreases in use of pharmaceutical opioids (p<0.001), opioid agonist treatment (p=0.007), and benzodiazepines (p=0.001). There was no evidence for any trend in the other polysubstance use profiles, although single drug class use increased (51.9% to 64.7%, p=0.031). The different polysubstance use profiles were variously associated with psychosocial factors, including unstable housing and very high psychological distress, and other drug use risk behaviours, including non-fatal overdose, receptive and/or distributive needle sharing, and reusing one's own needles. CONCLUSION Same day polysubstance use has remained relatively common among this sample over time, although the typology has changed. Collectively, our findings point to diverse drug use patterns among people who inject drugs and reiterate the need for a range of harm reduction, treatment, and support options.

Abstract
OBJECTIVES Fentanyl has contributed to a sharp rise in the toxicity of the unregulated drug supply and fatal overdoses in Canada. It has also changed injection practices. Injection frequency has increased as a result and so has equipment sharing and health-related risks. The aim of this analysis was to explore the impact of safer supply programs on injection practices from the perspective of clients and providers in Ontario, Canada. METHODS The data set included qualitative interviews with 52 clients and 21 providers that were conducted between February and October 2021 across four safer supply programs. Interview excerpts discussing injection practices were extracted, screened, coded and then grouped into themes. RESULTS We identified three themes, each theme corresponding to a change in injection practices. The first change was a decrease in the amount of fentanyl used and a decrease in injection frequency. The second change involved switching to injecting hydromorphone tablets instead of fentanyl. Finally, the third change was stopping injecting altogether and taking safer supply medications orally. CONCLUSION Safer supply programs can contribute to reducing injection-related health risks in addition to overdose risks. More specifically, they have the potential to address disease prevention and health promotion gaps that stand-alone downstream harm reduction interventions cannot address, by working upstream and providing a safer alternative to fentanyl.

Abstract
BACKGROUND Groin and neck injections are generally a last resort for people who inject drugs (PWID) who do not have easy access to functioning veins. These alternative injection practices can lead to an increased likelihood of adverse health outcomes. There is still much we do not know about groin and neck injections among PWID in the US, as the literature to-date comes from studies primarily focused on groin injections outside the US. We assessed prevalence, predictors, and associated behaviors of neck injection through a survey fielded in San Francisco, California, US. METHODS The sample comes from a longitudinal observational study that used targeted sampling to recruit PWID in San Francisco. The current study sample includes 239 PWID who completed their 12-month survey between June 2019 and June 2020. RESULTS About a third of the sample reported injecting in their neck in the past 30 days, with the most common reason being lack of available veins. Age, past 6-month abscess / soft tissue infection, and past 30-day use of opioids mixed with cocaine were significantly associated with past 30-day neck injection in the final multivariate model. Past 30-day neck injection was also significantly associated with being injected by another person in the past 30 days. CONCLUSIONS PWID at higher risk for vein deterioration were more likely to inject into their neck. Harm reduction strategies such as safer injection counseling, safe smoking supplies, use of "street doctors," and safe consumption sites may reduce instances of neck injection and/or associated health risks.

Abstract
We investigated the association between fentanyl injection frequency and sharing of injection equipment among people who inject drugs. We surveyed 249 people who inject drugs in Toronto in 2019. We estimated predicted probabilities of associations between fentanyl injection frequency and injection risk practices. In prior 6 months, 117 (47.0%) of participants injected fentanyl daily, 49 (19.7%) less than daily, and 78 (31.3%) did not inject fentanyl. Participants who injected fentanyl daily shared syringes more often than those not injecting fentanyl (25.0% vs. 4.9%; χ2 = 11.54, p = 0.0007). Participants who injected fentanyl daily (42.4% vs. 11.3%; χ2 = 18.05, p < 0.0001) and less than daily (37.2% vs. 11.3%; χ2 = 5.88 p = 0.02) shared cookers more often than those not injecting fentanyl. Participants who injected fentanyl daily (30.2% vs. 9.7%; χ2 = 9.05, p = 0.003) and less than daily (30.3% vs. 9.7%; χ2 = 4.11, p = 0.04) shared filters more often than those not injecting fentanyl. No differences in probabilities of sharing equipment were detected between participants who injected fentanyl daily and less than daily. People using fentanyl reported injection practices that increased risk for infectious disease transmission.

Abstract
Purpose
The emergence of fentanyl has deepened concerns about the opioid crisis. The shift has created new distinctions in patterns of opioid use, which may be important for prevention and intervention. This paper aims to examine sociodemographic correlates as well as health and substance use characteristics of different groups of opioid users.
Design/methodology/approach
This paper used the 2015–2019 National Survey on Drug Use and Health to examine distinctions between groups (n = 11,142) of individuals who misuse prescription opioids, use heroin but not fentanyl, misuse pharmaceutical fentanyl but not heroin and use both heroin and fentanyl. Multinomial and logistic regression models were used to identify these distinctions.
Findings
Few sociodemographic differences emerged between the prescription opioid group and pharmaceutical fentanyl misuse group. While those who misuse fentanyl have higher odds of using other drugs and experiencing certain mental health problems than those misusing prescription pills, both the heroin and fentanyl–heroin use groups reported considerably poorer health and substance use indicators relative to those who solely misuse fentanyl. It is also notable that both heroin use groups are more highly associated with cocaine and methamphetamine use than those misusing fentanyl alone.
Research limitations/implications
While this study identifies important distinctions between the opioid use groups studied, individuals using both heroin and pharmaceutical fentanyl report the poorest health and substance use characteristics. Important differences between the fentanyl-only group and the group who consume both drugs may have implications for prevention, intervention and clinical work amid shifting patterns of opioid use.
Practical implications
Important differences between the fentanyl-only group and the group who consume both drugs may have implications for prevention, intervention and clinical work amid shifting patterns of opioid use.
Originality/value
This study highlights distinctions between pharmaceutical fentanyl users, heroin users and users of both substances.

Abstract
BACKGROUND Injection drug use-associated bacterial and viral infections are increasing. Expanding access to harm reduction services, such as safe injection education, are effective prevention strategies. However, these strategies have had limited uptake. New tools are needed to improve provider capacity to facilitate dissemination of these evidence-based interventions. METHODS The "Six Moments of Infection Prevention in Injection Drug Use" provider educational tool was developed using a global, rather than pathogen-specific, infection prevention framework, highlighting the prevention of invasive bacterial and fungal infections in additional to viral pathogens. The tool's effectiveness was tested using a short, paired pre/post survey that assessed provider knowledge and attitudes about harm reduction. RESULTS Seventy-five respondents completed the paired surveys. At baseline, 17 respondents (22.6%) indicated that they had received no prior training in harm reduction and 28 (37.3%) reported discomfort counseling people who inject drugs (PWID). Sixty respondents (80.0%) reported they had never referred a patient to a syringe service program (SSP); of those, 73.3% cited lack of knowledge regarding locations of SSPs and 40.0% reported not knowing where to access information regarding SSPs. After the training, 66 (88.0%) reported that they felt more comfortable educating PWID (P < .0001), 65 respondents (86.6%) reported they planned to use the Six Moments model in their own practice, and 100% said they would consider referring patients to an SSP in the future. CONCLUSIONS The Six Moments model emphasizes the importance of a global approach to infection prevention and harm reduction. This educational intervention can be used as part of a bundle of implementation strategies to reduce morbidity and mortality in PWID.

Abstract
Drug overdose remains a leading cause of death in the US, with growing rates attributable to illicit fentanyl use. Recent HIV outbreaks among people who inject drugs (PWID) and service disruptions from COVID-19 have renewed concerns on HIV resurgence. We examined the relationship between fentanyl use and three injection-related HIV risk behaviors among PWID in Baltimore City (BC) and Anne Arundel Country (AAC), Maryland. PWID (N = 283) were recruited to the study through targeted sampling at street-based locations in BC and AAC from July 2018 to March 2020. Receptive syringe sharing (RSS) [adjusted odds ratio (AOR): 2.8, 95% confidence interval (CI): 1.2–6.3] and daily injecting (AOR: 1.9, 95% CI: 1.0–3.6) were associated with injecting fentanyl and cocaine together. Fentanyl availability and COVID-19 bring new HIV prevention challenges, particularly among those who inject fentanyl with cocaine, highlighting the importance to expand and sustain harm reduction, prevention, and treatment services for PWID to reduce HIV and overdose burden.

Drug Alcohol Depend 2021; 227:109003.

Abstract
BACKGROUND The introduction of illicitly made fentanyl in the United States has slowly replaced heroin. New illicit drugs are often associated with changes in frequency and modes of administration. We assessed changes in injection frequency and smoking fentanyl in the new era of fentanyl availability in San Francisco. METHODS We used targeted sampling to recruit 395 people who inject drugs (PWID) into an observational cohort study in San Francisco 2018-2020. We assessed changes in injection frequency, opioid injection frequency and fentanyl smoking frequency in four six-month periods. We also conducted qualitative interviews with PWID asking about motivations for injecting and smoking opioids. RESULTS The median number of past-month injections steadily decreased by semi-annual calendar year from 92 injections in July to December 2018 to 17 injections in January to June 2020. The rate of opioid injections reduced by half (Adjusted Incidence Rate Ratio = 0.41; 95 % Confidence Interval = 0.25, 0.70; p < 0.01). The number of days smoking fentanyl was associated with fewer number of injections (X2(2) = 11.0; p < 0.01). Qualitative interviews revealed that PWID's motivation for switching from injecting tar heroin to smoking fentanyl was related to difficulties accessing veins. After switching to smoking fentanyl, they noticed many benefits including how the drug felt, improved health, fewer financial constraints, and reduced stigma. CONCLUSION Between 2018 and 2020, there was a shift from injecting tar heroin to smoking fentanyl in San Francisco. Reductions in injection of illicit drugs may offer public health benefit if it reduces risk of blood-borne viruses, abscesses and soft-tissue infections, and infective endocarditis.

Abstract
Ensuring people who inject drugs (PWID) have ≥ 100% sterile syringe coverage (i.e., persons have access to a sterile syringe for all injections) is optimal for HIV prevention. Existing syringe coverage literature is informative, yet little work has examined syringe coverage among PWID in rural communities. Using data from a 2018 PWID population estimation study conducted in a rural county in West Virginia, we used logistic regression to identify correlates of adequate sterile syringe coverage (at least 100%). A minority (37%) of PWID reported having adequate syringe coverage. Factors inversely associated with adequate syringe coverage included having recently (past 6 months): engaged in transactional sex work, shared syringes, and injected fentanyl. Having exclusively acquired syringes from a syringe services program was associated with increased odds of adequate syringe coverage. Rural PWID may benefit from tailored interventions designed to increase sterile syringe access.

Abstract
BACKGROUND Attempts to reduce opioid overdoses have been complicated by the dramatic rise in fentanyl use. While market forces contributing to fentanyl proliferation in the illicit drug supply have increased inadvertent exposure to the drug, rising fentanyl use may also be driven by growing consumer demand. Interventions to reduce the spread of fentanyl must be based on an understanding of the motivations underlying its use. METHODS Data for this cross-sectional study were derived from a computerized self-administered survey completed by a convenience sample of 432 people who use illicit opioids (PWUO) recruited from methadone and detoxification programs in NJ. The anonymous survey was based on a prior qualitative study of attitudes and behaviors surrounding opioid use. Multivariate analysis identified correlates of intentional fentanyl use in the full sample and among sub-populations of white and non-white PWUO. RESULTS In the full sample, intentional fentanyl use was associated with white race/ethnicity, younger age, polydrug use, and a preference for the drug effects of fentanyl, which more than tripled the probability of intentional use (AOR=3.02; 95% CI=1.86-4.89; p=.000). Among whites, a preference for the fentanyl drug effects was also the strongest predictor of intentional use (AOR=5.34; 95% CI=2.78-10.28; p=.000). Among non-whites, however, exposure, not preference, was the primary driver of use, with intentional use more than doubling (AOR=2.48; 95% CI=1.04-5.91; p<.05) among those living in high fentanyl dispersion counties. CONCLUSION The motivations underlying fentanyl use are multifactorial and vary across populations of PWUO, indicating a need for targeted interventions to counter the increasing spread and adverse consequences of fentanyl use. In order to counteract the increasing spread and adverse consequences of fentanyl use, these findings indicate a need for harm-reduction interventions, like drug testing or supervised injection sites, that address the differing motivations for fentanyl use among PWUO.

Association of skin infections with sharing of injection drug preparation equipment among people who inject drugs. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2021; 94:103198. [PMID: 33744668 PMCID: PMC8373634 DOI: 10.1016/j.drugpo.2021.103198] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2020] [Revised: 03/01/2021] [Accepted: 03/02/2021] [Indexed: 11/22/2022]
Abstract
BACKGROUND Sharing needles and injection drug preparation equipment (IDPE) among people who inject drugs (PWID) are well-established risk factors for viral transmission. Shared needles and IDPE may serve as bacterial niduses for skin and soft tissue infections (SSTI). Given the rising rates of SSTI in PWID, we investigated the association of needle and IDPE sharing on incidence of SSTI in a cohort of PWID. METHODS Inpatient PWID (N = 252) were recruited to a randomized controlled trial of an intervention aimed at reducing infections. The primary outcome was self-reported incidence of SSTI one-year post-hospitalization. In this secondary analysis, we assessed two variables: 1) sharing of IDPE alone, 2) sharing needles with or without IDPE, and compared these groups separately to persons who reported no sharing of needles or IDPE via a mixed-effects negative binomial regression model to estimate the effect of baseline sharing behavior on SSTI during follow-up via incidence rate ratios (IRR). RESULTS Participant characteristics: 38 years [mean], 58% male, 60% White, 90% primarily injected opioids, 1.58 (± 2.35) mean SSTI in the year prior to baseline. In terms of sharing behavior, 29% didn't share needles or IDPE, 13% shared IDPE only, and 58% shared needles with or without IDPE three months prior to baseline. After adjusting for co-variables, PWID who shared IDPE alone had a 2.2 fold higher IRR of SSTI (95%CI 1.27; 3.85, p = 0.005) and PWID who shared needles with or without IDPE had a 3.31 fold higher IRR of SSTI (95%CI 2.04; 5.37, p < 0.001), compared to those who did not share any equipment. The number of SSTI at baseline was associated with an IRR of 1.20 of SSTI during follow-up (95%CI 1.09; 1.32, p < 0.001). CONCLUSIONS In this cohort of hospitalized PWID, we found a significant association between baseline sharing of IDPE alone and of sharing of needles with or without IDPE with one-year incidence of SSTI.

Prevalence and correlates of multiple non-fatal opioid overdoses among people who inject drugs who utilise needle syringe programs in Australia. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2021; 96:103245. [PMID: 33840562 DOI: 10.1016/j.drugpo.2021.103245] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2020] [Revised: 03/15/2021] [Accepted: 03/21/2021] [Indexed: 11/21/2022]
Abstract
BACKGROUND Non-fatal overdose (NFOD) is a major cause of morbidity among people who inject drugs (PWID) and multiple NFOD is associated with increased risk of fatal overdose. Despite this, few studies have examined the prevalence and correlates of drug-specific multiple NFOD. The current study aimed to determine the prevalence and correlates of recent multiple non-fatal opioid overdose (NFOOD) among PWID who access needle syringe programs (NSPs) in Australia. METHODS The Australian Needle and Syringe Program Survey is conducted annually and was conducted at 46 sites across Australia in 2019. Participation involves completion of a self-administered questionnaire and a capillary dried blood spot for HIV and hepatitis C virus testing. In 2019, respondents who reported a minimum of one NFOOD in the previous 12 months (recent NFOOD) were asked to complete supplementary questions regarding their last NFOOD. Bivariate and multivariate logistic regression were used to determine factors independently associated with multiple recent NFOOD. RESULTS A total of 222 respondents reported recent NFOOD. Respondents were predominantly male (59%), one third (39%) were aged less than 39 years and 73% reported last injecting heroin at their last NFOOD. One in two respondents (48%, n = 107) reported multiple opioid overdoses (median 3, interquartile range 2-5). The odds of reporting multiple NFOOD were higher among respondents who reported injecting in a public location at their last NFOOD (adjusted odds ratio [AOR] 2.10, 95% CI 1.14-3.90, p = 0.018) and benzodiazepine use in the 12 h prior to NFOOD (AOR 2.74, 95% CI 1.50-4.99, p = 0.001). CONCLUSIONS Multiple NFOOD was prevalent among PWID who utilised NSPs who reported recent NFOOD. Public injecting and benzodiazepine use were associated with increased risk of multiple NFOOD, and there is a need for interventions specifically targeting PWID who report these high risk injecting practices.

Abstract
Hepatitis C virus (HCV) infection remains an important cause of morbidity and mortality throughout the world, leading to serious health problems among those who are chronically infected. Since 1992, the Centers for Disease Control and Prevention has been collecting data on the incidence of HCV infection in the United States. In 2018, more than 50 000 individuals were estimated to have acute HCV infection.The most recently reported data on the prevalence of infection indicate that approximately 2.4 million people are living with hepatitis C in the United States. Transmission of HCV occurs predominantly through sharing contaminated equipment for injecting drugs.Two major events have had a significant impact on the incidence and prevalence of hepatitis C in the past few decades: the US opioid crisis and the discovery of curative treatments for HCV infection. To better understand the impact of these events, we examine reported trends in the incidence and prevalence of infection.

Abstract
AIMS To estimate incidence and predictors of opioid agonist therapy (OAT) discontinuation in a national cohort of people who inject drugs (PWID). DESIGN AND SETTING Annually repeated cross-sectional serosurveillance among PWID attending ~50 needle-syringe programmes across Australia. PARTICIPANTS Between 1995 and 2018, 2651 PWID who reported current OAT and had subsequent survey participation completed 6739 surveys. Respondents were followed over 11 984 person-years of observation (PYO). Respondents were predominantly male (60%), and the median age was 34 years. Heroin was the most commonly reported drug last injected (46%), and methadone was the most commonly prescribed OAT (77%). MEASUREMENTS The primary outcome was discontinuation of OAT (methadone, buprenorphine or buprenorphine-naloxone). Among respondents who reported current OAT, those who did not report current OAT in all subsequent records were defined as discontinued, and those with current OAT at all subsequent records were defined as retained. Predictors of discontinuation included self-reported demographic (sex, location, Indigenous status) and drug use characteristics (drug last injected, frequency of injection). FINDINGS Just fewer than one-third of respondents (29%) reported an OAT discontinuation event. The crude discontinuation rate was 6.3 [95% confidence intervals (CI) = 5.9-6.8] per 100 PYO. Discontinuation was significantly higher among respondents who reported last injecting pharmaceutical opioids [adjusted hazard ratio (aHR) = 1.75, 95% CI = 1.41-2.17, P < 0.001], being prescribed buprenorphine (aHR = 1.44, 95% CI = 1.18-1.76, P = 0.001) or buprenorphine-naloxone (aHR = 1.68, 95% CI = 1.20-2.34, P = 0.002), daily or more frequent injection (aHR = 1.51, 95% CI = 1.23-1.85, P < 0.001), recent public injecting (aHR = 1.37, 95% CI = 1.17-1.60, P < 0.001), incarceration in the previous 12 months (aHR = 1.31, 95% CI = 1.05-1.64, P = 0.017), recent receptive syringe or injection equipment sharing (aHR = 1.28, 95% CI = 1.10-1.48, P = 0.001) and male sex (aHR = 1.27, 95% CI = 1.09-1.47, P = 0.002). CONCLUSION People who inject drugs attending needle-syringe programmes in Australia appear to be significantly more likely to discontinue opioid agonist treatment if they were prescribed buprenorphine or buprenorphine-naloxone compared with methadone, are male or report injection risk behaviours and recent incarceration.

Abstract
BACKGROUND Over the last several years, fentanyl has been introduced into the illicit drug supply in the United States. While the impact of fentanyl on overdose fatalities is clear, the increase in fentanyl use may also be affecting drug use practices with implications for infectious disease transmission. We conducted a cross-sectional survey to explore associations of perceived illicit fentanyl use with opioid use frequency, injection frequency and syringe sharing among people who inject drugs in two California cities. METHODS People who inject drugs (PWID) were recruited from community settings in Los Angeles and San Francisco, CA from June 2017 to September 2018. Multivariable logistic regression was used to explore adjusted associations between perceived illicit fentanyl use and high frequency opioid use, high frequency injection and syringe sharing. RESULTS Among the 395 study participants, the median age of participants was 44 years; 74% of participants were cisgender male; 73% reported to be homeless; 61% lived in San Francisco and 39% in Los Angeles. The prevalence of perceived illicit fentanyl use in the past six months was 50.4% (95% confidence interval (CI): 45.4%-55.3%) among PWID. Findings from our adjusted logistic regression models suggested that people reporting perceived illicit fentanyl use had a greater odds of high frequency opioid use (adjusted odds ratio (aOR) = 2.36; 95% CI: 1.43-3.91; p = 0.001), high frequency injection (aOR = 1.84; 95% CI: 1.08-3.13; p = 0.03) and receptive syringe sharing (aOR = 2.16; 95% CI: 1.06-4.36; p = 0.03), as compared to people using heroin and other street drugs but not fentanyl. CONCLUSION People reporting perceived illicit fentanyl use were at increased risk for injection-related infectious disease risks. Actions must be taken to reduce these risks, including improved access to syringe service programs and opioid treatment and consideration of innovative approaches, such as supervised consumption services.

Abstract
Fentanyl is a powerful opioid anesthetic and analgesic, the use of which has caused an increasing public health threat in the United States and elsewhere. Fentanyl was initially approved and used for the treatment of moderate to severe pain, especially cancer pain. However, recent years have seen a growing concern that fentanyl and its analogs are widely synthesized in laboratories and adulterated with illicit supplies of heroin, cocaine, methamphetamine, and counterfeit pills, contributing to the exponential growth in the number of drug-related overdose deaths. This review summarizes the recent epidemic and evolution of illicit fentanyl use, its pharmacological mechanisms and side effects, and the potential clinical management and prevention of fentanyl-related overdoses. Because social, economic, and health problems that are related to the use of fentanyl and its analogs are growing, there is an urgent need to implement large-scale safe and effective harm reduction strategies to prevent fentanyl-related overdoses.

Abstract
AIMS To examine temporal trends in prescription opioid (PO) injection and to assess its association with hepatitis C virus (HCV) seroconversion among people who inject drugs (PWID). DESIGN Prospective cohort study spanning 2004 to 2016. SETTING Montréal, Canada. PARTICIPANTS PWID reporting injection during the past 6 months. MEASUREMENTS PWID were recruited between 2004 and 2016. At each 3-6-month follow-up visit, participants completed interview-administered questionnaires and were tested for HCV-antibody. FINDINGS Among 1524 PWID [83% males, mean age 38 years, standard deviation (SD) = 10, 34% (31-36) prescription opioid (PO) injection past month] included in trends analyses, PO injection use expanded between 2004 and 2009, and plateaued between 2010 and 2016 (trend tests < 0.001 and 0.335, respectively). Of the 432 HCV-seronegative PWIDs followed at least once (81% males, mean age 34, SD 9.8, 38% injection PO), 153 became HCV-antibody-positive during 1230 years of follow-up, for an incidence of 12.4 per 100 person-years [95% confidence interval (CI) = 10.6, 14.6]. PO injectors were 3.9 times more likely to seroconvert to HCV, relative to non-PO injectors. In a multivariate analysis, a stronger association between PO injection and HCV seroconversion was found post-2009 [adjusted hazard ratio (aHR) = 5.4, 95% CI = 2.7, 10.8] than before (aHR = 1.5, 95% CI = 0.9, 2.4) (P-value for interaction = 0.001). CONCLUSION Prescription opioid injection increased among people who inject drugs in Montréal, Canada from 2004 to 2009, to reach a plateau between 2010 and 2016. The association between prescription opioid injection and HCV seroconversion was stronger during the second period than the first according to the epidemic phase.
