Brummer J, Thylstrup B, Melis F, Hesse M. Predictors of retention in heroin-assisted treatment in Denmark 2010-2018 - A record-linkage study. JOURNAL OF SUBSTANCE USE AND ADDICTION TREATMENT 2024; 165:209449. [PMID: 38960145 DOI: 10.1016/j.josat.2024.209449] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Revised: 04/25/2024] [Accepted: 06/26/2024] [Indexed: 07/05/2024]
Abstract
INTRODUCTION While randomized-controlled trials have shown that heroin-assisted treatment (HAT) is superior to methadone maintenance alone in treatment of refractory clients, little is known about client factors associated with retention in HAT in routine care. METHODS This retrospective cohort study assessed predictors of retention in first treatment episode among a consecutive cohort of clients admitted to HAT in Denmark from 2010 to 2018, who could be matched to the Danish population register and for whom a Short Form Health Survey (SF-36) was available at admission (N = 432). The study derived predictors from client self-reports at intake and administrative data available in national registers. Cox proportional hazards regression modelled retention in treatment. RESULTS The one-year retention rate was 69.63 % (95 % CI 65.06 %-73.74 %), and the median time in treatment was 2.45 years (95 % CI, 1.83-3.12). Bivariate analyses showed that retention was lower for clients who had recent cocaine or benzodiazepine use and among those who had experienced an overdose in the year prior to enrollment in HAT. Age below 40, recent illegal activity, poorer emotional wellbeing, previous residential treatment experience, and previous intensive outpatient treatment were also predictors of dropout from HAT. CONCLUSIONS This observational study found that retention in HAT in routine care was similar to rates observed in randomized-controlled trials conducted in other countries. The results suggest that addressing polysubstance use as part of the HAT program may promote long-term retention, as may directing resources to certain subgroups identified at intake, including clients under 40 years and those who report recent criminal activity, emotional problems, or overdoses. The findings that previous residential treatment and intensive outpatient treatment were associated with dropout were unexpected.

Abstract
BACKGROUND In recent decades, maternal mortality has increased across the U.S. Experiences of pregnant and postpartum people with Substance Use Disorder (SUD)-related deaths have not been previously evaluated in New Mexico. The aim of this study was to analyze risk factors related to substance use and explore substance use patterns among pregnancy-associated deaths in New Mexico from 2015 to 2019. METHODS We conducted an analysis of pregnancy-associated deaths to assess the association between demographics, pregnancy factors, circumstances surrounding death, treatment of mental health conditions, and experiences with social stressors among Substance Use Disorder (SUD)-related and non-SUD-related deaths. We performed univariate analyses of risk factors using chi-square tests to assess the differences between SUD-related and non-SUD-related deaths. We also examined substance use at time of death. RESULTS People with SUD-related deaths were more likely to die 43-365 days postpartum (81% vs. 45%, p-value = 0.002), have had a primary cause of death of mental health conditions (47% vs 10%, p < 0.001), have died of an overdose (41% vs. 8%, p-value = 0.002), have had experienced any social stressors (86% vs 30%, p < 0.001) compared to people with non-SUD-related deaths, and received treatment for SUD at any point before, during, or after pregnancy (49% vs. 2%, p < 0.001). The substances most used at time of death were amphetamines (70%), and most cases engaged in polysubstance use (63%). CONCLUSIONS FOR PRACTICE Providers, health departments, and community organizations must prioritize supporting people using substances during and after pregnancy to prevent death and improve quality of life for pregnant and postpartum people.

Abstract
INTRODUCTION Substance use disorder (SUD) and overdose deaths are higher in the American Indian and Alaska Native (AIAN) population than in other racial/ethnic groups. Multi-level gaps hinder SUD treatment for AIAN patients. Few studies have engaged front-line clinicians and administrators of SUD treatment programs serving AIAN patients to identify barriers and facilitators to improve the implementation of effective treatment. METHODS We conducted key informant interviews with a diverse sample of providers and administrators of SUD treatment programs across California regarding barriers and facilitators to treatment for AIAN patients. An AIAN-majority community advisory board (CAB) guided the development of an interview guide and helped to recruit respondents from five types of SUD programs statewide. Using ATLAS.ti, the research team coded interviews and classified emergent themes as barriers and facilitators related to Outer, Inner, and Individual domains of the Consolidated Framework for Implementation Research (CFIR). RESULTS Representatives of 13 of 15 invited SUD treatment programs participated and 9 of the 13 interviewed self-identified as AIAN. Related to Outer Setting barriers from coded interviews, a dominant barrier was policies that defund or underfund SUD treatment, especially detoxification centers. Outer Setting facilitators included consistent Indian Health Service (IHS) eligibility criteria, judicial system connections for direct treatment access, and community programs advocating SUD treatment. Key themes related to barriers for the Inner Setting were limited bed capacity, poor coordination of intake and care, and lack of telehealth technology. Facilitators integrated mental health, linkage to external resources, and culturally centered care. Individual-level barriers were negative attitudes such as SUD stigma, distrust of governmental programs, and lack of transportation while individual engagement was facilitated by programs addressing negative attitudes and providing telemedicine for remote care. CONCLUSION The public health threat of SUD for the AIAN population mandates the implementation of interventions and policies that facilitate care. This qualitative study with primarily AIAN clinical leaders of SUD treatment highlights opportunities to improve care at multiple CFIR levels, focusing on capacity, coordination, culturally congruent care, and community initiatives to promote engagement.

[PMID: 37540514 PMCID: PMC10403778 DOI: 10.1001/jamanetworkopen.2023.27319] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/16/2023] [Accepted: 06/25/2023] [Indexed: 08/05/2023] Open
Abstract
Importance Concerns that take-home naloxone (THN) training may lead to riskier drug use (as a form of overdose risk compensation) remain a substantial barrier to training implementation. However, there was limited good-quality evidence in a systematic review of the association between THN access and subsequent risk compensation behaviors. Objective To assess whether THN training is associated with changes in overdose risk behaviors, indexed through injecting frequency, in a cohort of people who inject drugs. Design, Setting, and Participants This cohort study used prospectively collected self-reported behavioral data before and after THN training of participants in The Melbourne Injecting Drug User Cohort Study (SuperMIX). Annual interviews were conducted in and around Melbourne, Victoria, Australia, from 2008 to 2021. SuperMIX participants were adults who regularly injected heroin or methamphetamine in the 6 months preceding their baseline interview. The current study included only people who inject drugs who reported THN training and had participated in at least 1 interview before THN training. Exposure In 2017, the SuperMIX baseline or follow-up survey began asking participants if and when they had received THN training. The first THN training date that was recorded was included as the exposure variable. Subsequent participant interviews were excluded from analysis. Main Outcomes and Measures Injecting frequency was the primary outcome and was used as an indicator of overdose risk. Secondary outcomes were opioid injecting frequency, benzodiazepine use frequency, and the proportion of the time drugs were used alone. Fixed-effects generalized linear (Poisson) multilevel modeling was used to estimate the association between THN training and the primary and secondary outcomes. Time-varying covariates included housing status, income, time in study, recent opioid overdose, recent drug treatment, and needle and syringe coverage. Findings were expressed as incidence rate ratios (IRRs) with 95% CIs. Results There were 1328 participants (mean [SD] age, 32.4 [9.0] years; 893 men [67.2%]) who completed a baseline interview in the SuperMIX cohort, and 965 participants completed either a baseline or follow-up interview in or after 2017. Of these 965 participants, 390 (40.4%) reported THN training. A total of 189 people who inject drugs had pretraining participant interviews with data on injecting frequency and were included in the final analysis (mean [SD] number of interviews over the study period, 6.2 [2.2]). In fixed-effects regression analyses adjusted for covariates, there was no change in the frequency of injecting (IRR, 0.91; 95% CI, 0.69-1.20; P = .51), opioid injecting (IRR, 0.95; 95% CI, 0.74-1.23; P = .71), benzodiazepine use (IRR, 0.96; 95% CI, 0.69-1.33; P = .80), or the proportion of reported time of using drugs alone (IRR, 1.04; 95% CI, 0.86-1.26; P = .67) before and after THN training. Conclusions and Relevance This cohort study of people who inject drugs found no evidence of an increase in injecting frequency, along with other markers of overdose risk, after THN training and supply. The findings suggest that THN training should not be withheld because of concerns about risk compensation and that advocacy for availability and uptake of THN is required to address unprecedented opioid-associated mortality.

Nicotine limits avoidance conditioning with opioids without interfering with the ability to discriminate an opioid-interoceptive state. Pharmacol Biochem Behav 2023:173604. [PMID: 37487952 DOI: 10.1016/j.pbb.2023.173604] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Revised: 07/20/2023] [Accepted: 07/21/2023] [Indexed: 07/26/2023]
Abstract
Approximately 90 % of individuals undergoing treatment for opioid use disorder (OUD) report comorbid use of nicotine. As such, further investigation into underlying mechanisms contributing to the extreme comorbidity between nicotine and opioid use are warranted. Nicotine administration significantly escalates self-administration of opioids and this increase in motivational efficacy persists despite contingent punishment of opioid consumption. Additionally, both systemic and intra-insular administration of nicotine produces a rightward shift in the dose-response function in both morphine-induced conditioned place preference and taste avoidance paradigms, particularly at higher doses (5-20 mg/kg). Two possible interpretations arise from these outcomes. One is that nicotine may specifically affect learning about the malaise-inducing effects of morphine thus facilitating acceptance of higher doses of morphine. Another interpretation is that it more generally reduces sensitivity to the interoceptive effects of morphine such that higher doses are needed to produce comparable effects in nicotine-treated, relative to control, rats. To further address these possibilities, we asked whether nicotine administration interfered with the ability to discriminate the morphine interoceptive state, irrespective of its hedonic evaluation, at a dose that is impacted by nicotine in avoidance conditioning paradigms. First, we demonstrated that systemic nicotine pretreatment significantly attenuates taste avoidance induced by a low dose of morphine (3 mg/kg). Next, we used an occasion setting paradigm with this same dose of morphine to test whether systemic nicotine pretreatment interferes with the ability to discriminate between saline- and morphine-induced interoceptive states. Within this task, nicotine had no effect on the ability to effectively discriminate between the interoceptive effects of morphine and saline. Collectively, these data suggest that nicotine may be specifically altering the overall hedonic assessment of morphine perhaps by interfering with learning about its deleterious consequences.

Abstract
Abstract
The last few years have seen the emergence of new psychoactive substance among the homeless population, specifically synthetic cannabinoid receptor agonists. The purpose of this study is to investigate the knowledge and experiences of new psychoactive substances amongst users from the homeless population. An explanatory research design was applied using a semi-structured questionnaire with the focus on gaining insights on the prevalence, motivations and effects. Participants were recruited through convenience sampling from support organisations and charities UK-wide. Descriptive statistics and logistic regression were applied to analyse the data obtained from participant surveys. A total of 105 participants met the inclusion criteria and were in the age range of 18 to 64 years old. Almost 70% consumed new psychoactive substance products, which “Spice” was the most prevalent substance. Homeless users had consumed new psychoactive substance to escape reality and to self-treat themselves and stopped consumption due to the adverse effects. Adverse events were reported from the majority of the participants and led to more than 20% of the participants requiring medical treatment following hospitalisation. Findings from this study can contribute to the development of guidelines and policies that specifically address the needs of the homeless population who use new psychoactive substances.

Abstract
To date, epidemiological studies have not evaluated heroin-related deaths in the Middle East and North African regions, especially Saudi Arabia. All heroin-related postmortem cases reported at the Jeddah Poison Control Center (JPCC) over a 10-year period (21 January 2008 to 31 July 2018) were reviewed. In addition, liquid chromatography electrospray ionization tandem mass spectrometry (LC/ESI-MS/MS) was utilized to determine the 6-monoacetylmorphine (6-MAM), 6-acetylcodeine (6-AC), morphine (MOR), and codeine contents in unhydrolyzed postmortem specimens. Ninety-seven heroin-related deaths were assessed in this study, and they represented 2% of the total postmortem cases at the JPCC (median age, 38; 98% male). In the blood, urine, vitreous humor, and bile samples, the median morphine concentrations were 280 ng/mL, 1400 ng/mL, 90 ng/mL, and 2200 ng/mL, respectively; 6-MAM was detected in 60%, 100%, 99%, and 59% of the samples, respectively; and 6-AC was detected in 24%, 68%, 50%, and 30% of the samples, respectively. The highest number of deaths (33% of total cases) was observed in the 21-30 age group. In addition, 61% of cases were classified as "rapid deaths," while 24% were classified as "delayed deaths." The majority (76%) of deaths were accidental; 7% were from suicide; 5% were from homicide; and 11% were undetermined. This is the first epidemiological study to investigate heroin-related fatalities in Saudi Arabia and the Middle East and North African region. The rate of heroin-related deaths in Jeddah remained stable but increased slightly at the end of the study period. Most patients were heroin-dependent abusers and from the middle-aged group. The availability of urine, vitreous humor, and bile specimens provided valuable information regarding the opioids that were administered and the survival time following heroin injection.

Abstract
BACKGROUND People who experience incarceration are at increased risk of asthma and have a higher prevalence of risk factors associated with asthma-related mortality. However, there has been little research on the relationship between asthma and mortality in people released from prison. OBJECTIVES This study examined the association between asthma and all-cause and cause-specific mortality, and estimated the increased risk of asthma-related mortality among adults released from prison compared to the age- and sex-matched general population. DESIGN We used data from a nested case-control sample (N = 1658) within a retrospective cohort study of all adults released from prisons in Queensland, Australia, from 1994 to 2007 (N = 42015). Deaths were identified using linkage to national mortality records. Nested study cases were sampled from deaths, with a matched control from the cohort. We examined medical and case management records to identify risk factors potentially associated with mortality. Asthma-related mortality in the cohort was compared to that of the matched general population of Queensland. RESULTS People released from prison were more likely than their age and sex matched general population counterparts to have an asthma-related death (HR = 3.32 95%CI:2.14-5.16). Those who had been identified as having asthma in prison had increased odds of mortality from all-cause (OR = 1.86 95%CI:1.40-2.47), drug-related (OR = 2.5 95%CI:1.40-4.46), cardiovascular-related (OR = 3.2 95%CI:1.57-6.51), and respiratory-related (OR = 3.30 95%CI:1.63-6.70). CONCLUSION Among people exposed to incarceration, those with asthma are at elevated risk of death after release from custody. Improved management of respiratory disease in this population may contribute to reducing their high rate of preventable mortality.

Discontinuation and tapering of prescribed opioids and risk of overdose among people on long-term opioid therapy for pain with and without opioid use disorder in British Columbia, Canada: A retrospective cohort study. PLoS Med 2022; 19:e1004123.

Abstract
BACKGROUND The overdose crisis in North America has prompted system-level efforts to restrict opioid prescribing for chronic pain. However, little is known about how discontinuing or tapering prescribed opioids for chronic pain shapes overdose risk, including possible differential effects among people with and without concurrent opioid use disorder (OUD). We examined associations between discontinuation and tapering of prescribed opioids and risk of overdose among people on long-term opioid therapy for pain, stratified by diagnosed OUD and prescribed opioid agonist therapy (OAT) status. METHODS AND FINDINGS For this retrospective cohort study, we used a 20% random sample of residents in the provincial health insurance client roster in British Columbia (BC), Canada, contained in the BC Provincial Overdose Cohort. The study sample included persons aged 14 to 74 years on long-term opioid therapy for pain (≥90 days with ≥90% of days on therapy) between October 2014 and June 2018 (n = 14,037). At baseline, 7,256 (51.7%) persons were female, the median age was 55 years (quartile 1-3: 47-63), 227 (1.6%) persons had been diagnosed with OUD (in the past 3 years) and recently (i.e., in the past 90 days) been prescribed OAT, and 483 (3.4%) had been diagnosed with OUD but not recently prescribed OAT. The median follow-up duration per person was 3.7 years (quartile 1-3: 2.6-4.0). Marginal structural Cox regression with inverse probability of treatment weighting (IPTW) was used to estimate the effect of prescribed opioid treatment for pain status (discontinuation versus tapered therapy versus continued therapy [reference]) on risk of overdose (fatal or nonfatal), stratified by the following groups: people without diagnosed OUD, people with diagnosed OUD receiving OAT, and people with diagnosed OUD not receiving OAT. In marginal structural models with IPTW adjusted for a range of demographic, prescription, comorbidity, and social-structural exposures, discontinuing opioids (i.e., ≥7-day gap[s] in therapy) was associated with increased overdose risk among people without OUD (adjusted hazard ratio [AHR] = 1.44; 95% confidence interval [CI] 1.12, 1.83; p = 0.004), people with OUD not receiving OAT (AHR = 3.18; 95% CI 1.87, 5.40; p < 0.001), and people with OUD receiving OAT (AHR = 2.52; 95% CI 1.68, 3.78; p < 0.001). Opioid tapering (i.e., ≥2 sequential decreases of ≥5% in average daily morphine milligram equivalents) was associated with decreased overdose risk among people with OUD not receiving OAT (AHR = 0.31; 95% CI 0.14, 0.67; p = 0.003). The main study limitations are that the outcome measure did not capture overdose events that did not result in a healthcare encounter or death, medication dispensation may not reflect medication adherence, residual confounding may have influenced findings, and findings may not be generalizable to persons on opioid therapy in other settings. CONCLUSIONS Discontinuing prescribed opioids was associated with increased overdose risk, particularly among people with OUD. Prescribed opioid tapering was associated with reduced overdose risk among people with OUD not receiving OAT. These findings highlight the need to avoid abrupt discontinuation of opioids for pain. Enhanced guidance is needed to support prescribers in implementing opioid therapy tapering strategies with consideration of OUD and OAT status.

Abstract
AIM To differentiate the severity of acute opioid toxicity and describe both the clinical and physiological features associated with heroin overdose in a cohort of witnessed overdose cases. METHODS Witnessed heroin overdose cases over a 12-month period (30 June 2018 - 30 June 2019) at the Medically Supervised Injecting Room (MSIR) in Melbourne, Australia were examined. The severity of acute opioid toxicity was classified according to the level of clinical intervention required to manage the overdose cases where an escalating level of care was provided. Heroin overdose cases were classified into one of three graded severity categories and a fourth complicated heroin overdose category. RESULTS A total of 1218 heroin overdose cases were identified from 60,693 supervised injecting visits over the study period. On the spectrum of toxicity, 78% (n = 955) of overdose cases were classified as Grade 1 severity, 7% (n = 83) as Grade 2 severity, and 13% (n = 161) as Grade 3 acute opioid toxicity severity cases, as well as 2% (n = 19) classified as complicated heroin overdose cases. The median onset time for heroin overdose cases was 17 min (IQR 11-28 min) from the time the individual was ready to prepare and inject heroin until clinical intervention was initiated. CONCLUSION We demonstrated that heroin overdose is a dynamic illness and cases differ in the severity of acute opioid toxicity. The risk of airway occlusion including positional asphyxia was an early and consistent feature across all levels of toxicity, while exaggerated respiratory depression together with exaggerated depression of consciousness was increasingly observed with greater levels of toxicity. We also demonstrated the importance of early intervention in overdose cases, where in a large cohort of heroin overdose cases there were no fatal outcomes, a very low hospitalisation rate and most cases were able to be managed to clinical resolution on-site.

[PMID: 35927753 PMCID: PMC9351099 DOI: 10.1186/s13722-022-00325-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2022] [Accepted: 07/25/2022] [Indexed: 11/24/2022] Open
Abstract
Background As a public health issue, non-fatal overdose (NFOD) is highly prevalent among people who inject drugs (PWID). This can lead to an elevated risk of future overdose, causing various harms including possible death. It is essential to improve knowledge concerning this problem and its associated risk factors to inform overdose prevention and assistance programs. The primary aim of the present study was to determine the prevalence of NFOD and associated risk factors among PWID in Saveh, Iran. Methods In the present cross-sectional study, 272 PWID living in Saveh, Iran were interviewed face-to-face using a structured survey. Data concerning socio-demographics, substance use, risky behaviors, and services utilization data were collected. The outcome variable (i.e., NFOD) was assessed by answering “Yes” to the question: “In the past three months, have you ever overdosed (at least once) by accident?” Results The prevalence of NFOD among PWID in the past three months was 54%. The characteristics and behaviors that were associated with an increased risk of experiencing NFOD in the past three months were being of older age (AOR = 5.2, p < 0.05), drug use initiation under the age of 22 years (AOR = 7.8, p < 0.05), being an alcohol user (AOR = 3.0, p < 0.05), and being a simultaneous multiple drug user (AOR = 5.8, p < 0.05). Also, more recent initiates to injecting (< 2 years) had an increased risk of experiencing a non-fatal overdose in the past three months. Findings also indicated that those who (i) attended a needle and syringe program (AOR: 0.3, p < 0.05), (ii) were visited by a general practitioner (AOR: 0.03, p < 0.05), and (iii) received a psychosocial intervention (AOR: 0.1, p < 0.05) were 0.3, 0.03 and 0.1 times less likely to report non-fatal overdosing than other participants, respectively. Conclusions The results indicate that intervention and prevention initiatives seeking to reduce NFOD among PWID should not only be focused on the primary drug used but also the use of alcohol and polysubstance use. Specific and tailored psychological interventions combined with pharmacotherapy may be highly beneficial for PWID who experience more severe types of substance use, including alcohol use disorders and/or polysubstance abuse.

Substance Use, Hospitalizations, and Co-Occurring Disorders among Patients Transferred from a Needle Exchange Program to Opioid Maintenance Treatment. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19020697. [PMID: 35055519 PMCID: PMC8775654 DOI: 10.3390/ijerph19020697] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/30/2021] [Revised: 12/28/2021] [Accepted: 01/05/2022] [Indexed: 11/16/2022]
Abstract
Opioid use disorders (OUD) is a relapsing condition with high mortality. Opioid maintenance treatment (OMT) reduces heroin use, and overall morbidity and mortality. The prevalence of psychiatric and substance use disorders, potential baseline predictors for psychiatric hospitalization, and psychiatric diagnoses at follow-up were investigated and may give hints about possible preventative strategies. The medical records for 71 patients were reviewed 36 months following referral to OMT from a needle exchange program (NEP). Their psychiatric diagnoses and hospitalizations were identified. Their baseline characteristics were assessed for potential differences between hospitalized versus non-hospitalized patients and between patients with and without psychiatric diagnoses in a longitudinal observational study without controls. A regression analysis was performed to identify predictors for hospitalization when controlling for OMT status. Sixty-five percent of the patients were hospitalized at least once with a psychiatric diagnosis. Substance-related reasons were prevalent, and detoxification occurred among 59% of patients, with sedative- hypnotics (benzodiazepines, zopiclone, zolpidem, and pregabalin) being the substance used by 52% of patients. Baseline use of these drugs and/or buprenorphine predicted for hospitalization when controlling for OMT status. During the follow-up period, 72% of patients met the criteria for a psychiatric diagnosis other than OUD. The prevalence of non-substance use disorders overlapping with SUD was 41%, and that overlapping with anxiety disorder was 27% of all participants. Increased attention to psychiatric co-occurring disorders in the treatment of OUD is required and the importance of addressing sedative-hypnotics use when initiating OMT is highlighted.

Treatment of overdose in the synthetic opioid era. Pharmacol Ther 2021; 233:108019.

Abstract
Overdose deaths are often viewed as the leading edge of the opioid epidemic which has gripped the United States over the past two decades (Skolnick, 2018a). This emphasis is perhaps unsurprising because opioid overdose is both the number-one cause of death for individuals between 25 and 64 years old (Dezfulian et al., 2021) and a significant contributor to the decline in average lifespan (Dowell et al., 2017). Exacerbated by the COVID 19 pandemic, it was estimated there were 93,400 drug overdose deaths in the United States during the 12 months ending December 2020, with more than 69,000 (that is, >74%) of these fatalities attributed to opioid overdose (Ahmad et al., 2021). However, the focus on mortality statistics (Ahmad et al., 2021; Shover et al., 2020) tends to obscure the broader medical impact of nonfatal opioid overdose. Analyses of multiple databases indicate that for each opioid-induced fatality, there are between 6.4 and 8.4 non-fatal overdoses, exacting a significant burden on both the individual and society. Over the past 7-8 years, there has been an alarming increase in the misuse of synthetic opioids ("synthetics"), primarily fentanyl and related piperidine-based analogs. Within the past 2-3 years, a structurally unrelated class of high potency synthetics, benzimidazoles exemplified by etonitazene and isotonitazene ("iso"), have also appeared in illicit drug markets (Thompson, 2020; Ujvary et al. 2021). In 2020, it was estimated that over 80% of fatal opioid overdoses in the United States now involve synthetics (Ahmad et al., 2021). The unique physicochemical and pharmacological properties of synthetics described in this review are responsible for both the morbidity and mortality associated with their misuse as well as their widespread availability. This dramatic increase in the misuse of synthetics is often referred to as the "3rd wave" (Pardo et al., 2019; Volkow and Blanco, 2020) of the opioid epidemic. Among the consequences resulting from misuse of these potent opioids is the need for higher doses of the competitive antagonist, naloxone, to reverse an overdose. The development of more effective reversal agents such as those described in this review is an essential component of a tripartite strategy (Volkow and Collins, 2017) to reduce the biopsychosocial impact of opioid misuse in the "synthetic era".

Abstract
Background People who use drugs (PWUD) are known to fear calling emergency medical services (EMS) for drug overdoses. In response, drug-related Good Samaritan Laws (GSLs) have been widely adopted in the USA and Canada to encourage bystanders to call emergency medical services (EMS) in the event of a drug overdose. However, the effect of GSLs on EMS-calling behaviours has been understudied. We sought to identify factors associated with EMS-calling, including the enactment of the Canadian GSL in May 2017, among PWUD in Vancouver, Canada, a setting with an ongoing overdose crisis. Methods Data were derived from three prospective cohort studies of PWUD in Vancouver in 2014–2018. Multivariable logistic regression was used to determine factors associated with EMS-calling among PWUD who witnessed an overdose event. An interrupted time series (ITS) analysis was employed to assess the impact of GSL on monthly prevalence of EMS-calling. Results Among 540 eligible participants, 321 (59%) were males and 284 (53%) reported calling EMS. In multivariable analysis, ever having administered naloxone three or more times (adjusted odds ratio [AOR] 2.00; 95% confidence interval [CI] 1.08–3.74) and residence in the Downtown Eastside (DTES) neighbourhood of Vancouver (AOR 1.96; 95% CI 1.23–3.13) were positively associated with EMS-calling, while living in a single occupancy hotel (SRO) was negatively associated with EMS-calling (AOR 0.51; 95% CI 0.30–0.86). The post-GSL enactment period was not associated with EMS-calling (AOR 0.81; 95% CI 0.52–1.25). The ITS found no significant difference in the monthly prevalence of EMS-calling between pre- and post-GSL enactment periods. Conclusion We observed EMS being called about half the time and the GSL did not appear to encourage EMS-calling. We also found that individuals living in SROs were less likely to call EMS, which raises concern given that fatal overdose cases are concentrated in SROs in our setting. The link between many naloxone administrations and EMS-calling could indicate that those with prior experience in responding to overdose events were more willing to call EMS. Increased efforts are warranted to ensure effective emergency responses for drug overdoses among PWUD.

Abstract
BACKGROUND The aim of this study was to assess the epidemiological profile of unintentional opioid overdoses, the prevalence and number of psychotropic substances involved in opioid overdoses. METHODS This was a descriptive study, in which 180 participants were enrolled, and covered a nine-years-period. For collecting data was used the National patient electronic system "My term". The variables as gender, age, duration of opioid dependence, number of overdoses, type of substance, number of antidote ampoules, duration of hospitalization were analyzed. Severity of poisoning was made by using the Poison severity score. RESULTS Opioid overdose cases were significantly higher among males than females. Mean age with standard deviation (SD) was 32.23 ± 6.71 years. Mean years (±SD) of duration of opioid use disorder was 11.60 ± 5.89 years. The most commonly used primary substance was methadone in 68.89% and heroin in 31.11% cases. Twenty patients were treated with mechanical ventilation because of the severe respiratory depression. Poison severity score was moderate in 51.11%, severe in 45.56% and fatal in 3.33% of the cases. CONCLUSION Most of the cases, predominantly males used one or two substances. The combination of methadone and benzodiazepine was most frequently used and the most common way was by injecting the abused substances. In most of the subjects PSS score was moderate and severe with no differences between genders.

Abstract
In the midst of an escalating U.S. opioid crisis, the immediate focus of public health interventions is on fatal overdose prevention. Few studies, however, have sought to examine the long-term health consequences of exposure to repeated nonfatal opioid overdose. We reviewed recent literature to examine three corresponding downstream health outcomes of repeated overdose: a) neurodegenerative processes; b) cognition and memory; and c) overdose risk behaviours. We found a remarkable congruency among available biochemical and cognitive data on how nonfatal overdose precipitates various pathological feedforward and feedback loops that affect people who use opioids for years to come. We found however that downstream behavioural implications of neurodegenerative and cognitive sequelae are less studied despite being most proximal to an overdose. Findings point to a vicious cycle of nonfatal overdose leading to neurodegeneration - closely resembling Alzheimer Disease - that results in cognitive decline that in turn leads to potentially reduced adherence to safe drug use behaviours. The collected evidence not only brings into the focus the long-term health consequences of nonfatal overdose from the perspectives of biology, neuroscience, and public health, but also creates new cross-disciplinary context and awareness in the research and public health community that should benefit people at risk.

Abstract
Sweden and many other countries have experienced increases in suicide and accidental overdose deaths. An analysis examined the associations between recency of non-medical opioid misuse and frequency of use of non-medical opioids with death due to either suicide or accidental overdose within a sample of 15,000 Swedish adults who completed an Addiction Severity Index (ASI) assessment for risky substance use or a substance use disorder. METHODS AND MATERIALS Suicide (n = 136) and death due to overdose (n = 405) were identified in the official Cause of Death Registry from the Swedish National Board of Health and Welfare. Control variables included demographic characteristics and risks associated with either overdose or suicide. Cox regression analyses controlled for variables statistically significantly at the bivariate level. RESULTS At the multivariable level: a) a higher (modified) ASI Composite Score for mental health; b) history of suicide attempt; c) having used non-medical opioids for 1-2 times per week for at least a year; d) history of injection drug use; and, e) early onset of drug use, were all significantly and positively associated with death due to suicide. At the multivariable level: a) a higher the revised ASI Composite Score for mental health; b) recency of use of non-medical opioids; c) frequency of non-medical opioid use; d) being a male; and e) being of ages 18-24 years compared to ages 43-51 years were all positively and significantly associated with death due to accidental overdose. CONCLUSION These findings underscore the need to integrate mental health and substance use disorder treatment and provide suicide and overdose prevention interventions for individuals with an opioid use disorder. Recency and frequency of non-medical opioids were only associated with death due to overdose and not suicide. However, other drug use related variables (using opioids 1-2 times per week for at least a year, early onset of drug use and drug injection) were significantly associated with death due to suicide.

Abstract
The present study aimed to determine the association between drug type, risk behaviors and non-fatal overdose among people who use drugs (PWUD). We searched for studies in English published before February 1, 2021, on PubMed, Scopus, Cochrane, and Web of Science to identify primary studies on the factors associated with non-fatal overdose among PWUD. After reviewing for study duplicates, the full-text of selected articles were assessed for eligibility using Population, Intervention, Comparator, Outcomes (PICO) criteria. After a detailed assessment of over 13,845 articles, a total of 49 studies met the eligibility criteria. We found that non-injection opioid use, heroin injection, cocaine use, concurrent use of buprenorphine and benzodiazepines, benzodiazepine use, incarceration, injecting drugs, and duration of injecting were associated with greater odds of non-fatal overdose among PWUD. The findings of the current meta-analysis support the requirement to improve suitable harm reduction strategies for drug users, such as peer-based overdose management, and further focusing on the need to balance the current emphasis on enforcement-based responses to illegal drug use with health-related interventions.

Abstract
BACKGROUND People recently released from prison are at increased risk of preventable death; however, the impact of the current overdose epidemic on this population is unknown. We aimed to document the incidence and identify risk factors for fatal overdose after release from provincial prisons in British Columbia. METHODS We conducted a retrospective, population-based, open cohort study of adults released from prisons in BC, using linked administrative data. Within a random 20% sample of the BC population, we linked provincial health and correctional records from 2010 to 2017 for people aged 23 years or older as of Jan. 1, 2015, who were released from provincial prisons at least once from 2015 to 2017. We identified exposures that occurred from 2010 to 2017 and deaths from 2015 to 2017. We calculated the piecewise incidence of overdose-related and all-cause deaths after release from prison. We used multivariable, mixed-effects Cox regression to identify predictors of all-cause death and death from overdose. RESULTS Among 6106 adults released from prison from 2015 to 2017 and followed in the community for a median of 1.6 (interquartile range 0.9-2.3) years, 154 (2.5%) died, 108 (1.8%) from overdose. The incidence of all-cause death was 16.1 (95% confidence interval [CI] 13.7-18.8) per 1000 person-years. The incidence of overdose deaths was 11.2 (95% CI 9.2-13.5) per 1000 person-years, but 38.8 (95% CI 3.2-22.6) in the first 2 weeks after release from prison. After adjustment for covariates, the hazard of overdose death was 4 times higher among those who had been dispensed opioids for pain. INTERPRETATION People released from prisons in BC are at markedly increased risk of overdose death. Overdose prevention must go beyond provision of opioid agonist treatment and naloxone on release to address systemic social and health inequities that increase the risk of premature death.

Abstract
Analysis of postmortem samples with the presence of morphine can sometimes be challenging to interpret. Tolerance complicates interpretation of intoxications and causes of death due to overlap in therapeutic and fatal concentrations. Determination of metabolites and metabolic ratios can potentially differentiate between abstinence, continuous administration, and perhaps time of administration. The purpose of this study was to (a) develop and validate a method for quantitation of morphine-3β-D-glucuronide, morphine-6β-D-glucuronide, normorphine, codeine-6β-D-glucuronide, norcodeine, codeine, 6-acetylmorphine, and ethylmorphine in urine using liquid chromatography–tandem mass spectrometry; (b) apply the method to opiate related deaths; (c) compare metabolic ratios in urine in different causes of death (CoD) and after different drug intakes and (d) compare heroin intoxications in rapid and delayed deaths. Validation parameters such as precision, bias, matrix effects, stability, process efficiency, and dilution integrity were assessed and deemed acceptable. Lower limits of quantitation ranged from 0.01–0.2 μg/mL for all analytes. Autopsy cases (n=135) with paired blood and urine samples were analyzed. Cases were divided into three groups based on CoD; opiate intoxication, intoxication with other drugs than opiates, and other CoD. The cases were classified by intake: codeine (n=42), heroin (n=36), morphine (n=49), and ethylmorphine (n=3). Five cases were classified as mixed intakes and excluded. Heroin intoxications (n=35) were divided into rapid (n=15) or delayed (n=20) deaths. Parent drug groups were compared using metabolic ratio morphine-3β-D-glucuronide/morphine and significant differences were observed between codeine vs morphine (p=0.005) and codeine vs heroin (p≤0.0001). Urine and blood concentrations, and metabolic ratios in rapid and delayed heroin intoxications were compared and determined a significant difference for morphine (p=0.001), codeine (p=0.009), 6-acetylmorphine (p=0.02) in urine, and morphine (p=0.02) in blood, but there was no significant difference (p=0.9) between metabolic ratios. Morphine-3β-D-glucuronide results suggested a period of abstinence prior to death in 25% of the heroin intoxications.

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
BACKGROUND Being recently released from prison or discharged from hospital, or being dispensed opioids, benzodiazepines, or antipsychotics have been associated with an increased risk of fatal drug overdose. This study aimed to examine the association between these periods and non-fatal drug overdose using a within-person design. METHODS In this self-controlled case series, we used data from the provincial health insurance client roster to identify a 20% random sample of residents (aged ≥10 years) in British Columbia, Canada between Jan 1, 2015, and Dec 31, 2017 (n=921 346). Individuals aged younger than 10 years as of Jan 1, 2015, or who did not have their sex recorded in the client roster were excluded. We used linked provincial health and correctional records to identify a cohort of individuals who had a non-fatal overdose resulting in medical care during this time period, and key exposures, including periods of incarceration, admission to hospital, emergency department care, and supply of medications for opioid use disorder (MOUD), opioids for pain (unrelated to MOUD), benzodiazepines, and antipsychotics. Using a self-controlled case series, we examined the association between the time periods during and after each of these exposures and the incidence of non-fatal overdose with case-only, conditional Poisson regression analysis. Sensitivity analyses included recurrent overdoses and pre-exposure risk periods. FINDINGS We identified 4149 individuals who had a non-fatal overdose in 2015-17. Compared with unexposed periods (ie, all follow-up time that was not part of a designated risk period for each exposure), the incidence of non-fatal overdose was higher on the day of admission to prison (adjusted incidence rate ratio [aIRR] 2·76 [95% CI 1·51-5·04]), at 1-2 weeks (2·92 [2·37-3·61]), and 3-4 weeks (1·34 [1·01-1·78]) after release from prison, 1-2 weeks after discharge from hospital (1·35 [1·11-1·63]), when being dispensed opioids for pain (after ≥4 weeks) or benzodiazepines (entire use period), and from 3 weeks after discontinuing antipsychotics. The incidence of non-fatal overdose was reduced during use of MOUD (aIRRs ranging from 0·33 [0·26-0·42] to 0·41 [0·25-0·67]) and when in prison (0·12 [0·08-0·19]). INTERPRETATION Expanding access to and increasing support for stable and long-term medication for the management of opioid use disorder, improving continuity of care when transitioning between service systems, and ensuring safe prescribing and medication monitoring processes for medications that reduce respiratory function (eg, benzodiazepines) could decrease the incidence of non-fatal overdose.

Correlation study between anatomopathological data and levels of blood morphine concentrations in heroin-related deaths. Leg Med (Tokyo) 2021; 51:101877.

Abstract
Heroin-related mortality is a complex phenomenon involving several factors that make an individual more susceptible to opioid toxicity. Among these, pre-existing pathological conditions play an important role. The current paper reviewed 51 autopsied cases performed over the last 30 years, each subject ("frequent heroin user") having taken heroin intravenously alone before death. For each case, total blood morphine concentration determined by gas chromatography-mass spectrometry (GC-MS) was obtained from the archives. For histopathological evaluation we examined microscopic sections of the heart, lung, brain, liver and kidney, and for each organ a score table with a numerical value from 1 to 5, as an indicator of increasing severity, was drawn up. Finally, we created a scoring system based on the Injury Severity Score (ISS), generated by the sum of the squares of the three highest organ scores. We investigated the relationship between total blood morphine value (mg/l) and pathological score by inserting the two variables in a linear regression model: Score = a + b·Morphinemia (p-value <0.001). The results demonstrated a statistically significant correlation between the two variables: individuals with low total blood morphine values tended to have a higher pathological score. Our study provides useful assessment tools for forensic practice, confirming the need to combine two important disciplines in drug death investigation: forensic pathology and toxicology.

Abstract
AIMS To estimate the prevalence of and risk factors associated with concurrent injection of multiple substances (co-injection) among a community-recruited cohort of people who inject drugs. DESIGN Cross-sectional study. SETTING Melbourne, Australia. PARTICIPANTS A sample of 720 actively injecting participants from the Melbourne Injecting Drug User Cohort Study (33% female) was extracted. MEASUREMENTS We constructed two statistical models: a logistic regression model analysing correlates of co-injection of any substance combination in the past month and a multinomial logistic regression model analysing correlates of three mutually exclusive groups: heroin-diphenhydramine co-injection only, co-injection of other substances and no co-injection. Risk factors examined included drug use characteristics, demographic characteristics, health service use, hepatitis C status, injection risk behaviours and previous experience of non-fatal overdose. FINDINGS One-third [n = 226, 31%; 95% confidence interval (CI): 28-34%] of participants reported co-injecting substances within the past month, with equal numbers of participants reporting injecting combinations of heroin-diphenhydramine (n = 121, 54%; 95% CI = 48-60%) and heroin-methamphetamine (n = 121, 54%; 95% CI = 48-60%). In logistic regression analyses, reporting co-injection of any substance combination was associated with male sex [adjusted odds ratio (aOR) = 1.80, 95% CI = 1.18-2.74, P = 0.006] and injecting daily or more frequently (aOR = 2.04, 95% CI = 1.31-3.18, P = 0.002). In multinomial logistic regression analyses, participants reporting heroin-diphenhydramine co-injection only were significantly more likely to report groin injecting [adjusted relative risk ratio (aRRR) = 6.16, 95% CI = 2.80-13.56, P < 0.001] and overdose (requiring an ambulance) in the past 12 months (aRRR = 2.81, 95% CI = 1.17-6.72, P = 0.021) compared with participants reporting no co-injection or co-injection of other substances. CONCLUSIONS A substantial proportion of people who inject drugs report co-injection of multiple substances, which is associated with a range of socio-demographic, drug use and health service use risk factors.

Past 12-month nonfatal overdose among people who inject drugs in Ukraine: City-level estimates and risk factors from a cross-sectional study. Drug Alcohol Depend 2021; 220:108513. [PMID: 33556695 DOI: 10.1016/j.drugalcdep.2021.108513] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2020] [Revised: 12/14/2020] [Accepted: 12/16/2020] [Indexed: 11/20/2022]
Abstract
BACKGROUND Nonfatal overdose contributes to high morbidity and is among the strongest proxies for the occurrence of overdose fatality - the leading cause of death among those who use opioids. In Ukraine, a majority of people who inject drugs (PWID) use opioids, but little is known about the relationship between drug market characteristics, nonfatal overdose (NFOD) prevalence, and risk factors for NFOD. METHODS We used cross-sectional respondent-driven sampling (RDS) data to explore the variability of recent (past 12 months) NFOD among PWID across Ukrainian cities and associations with individual factors. The population-averaged -cross-sectional associations were estimated and compared using generalized linear models for the binary outcome (NFOD vs. not) with robust variance estimates. RESULTS Recent self-reported NFOD varied between 1% and 14 % across Ukrainian cities. In adjusted analyses, overdose was associated with fewer years of injecting drugs; a higher number of types of drugs used in the past 12 months; using desomorphine, methadone, tramadol, heroin, amphetamine-type drugs or cocaine within past 12 months; using alcohol daily or weekly; recent drug treatment; and history of incarceration. Buying drugs or their ingredients through "stashes" (i.e., drugs secretly hidden in various places) and the perception of drug price increase were associated with higher odds of reporting NFOD. CONCLUSION The identified risk factors underscore the importance of evidence-based prevention efforts, such as scaling-up opioid agonist therapy, providing naloxone in the community and upon prison release, targeting those most likely to witness overdose and sharing overdose prevention strategies with them, and continuous monitoring of trends and contributing factors.

Abstract
BACKGROUND Immediately after experiencing a non-fatal overdose, many people who inject drugs (PWID) engage in harm-minimizing behavior change, including engagement in drug treatment. To inform the implementation of tailored interventions designed to facilitate drug treatment engagement in rural communities, we sought to identify correlates of starting any form of drug treatment after their most recent overdose among PWID who reside in a rural county in West Virginia. METHODS Data are from a PWID population estimation study in Cabell County, West Virginia. We used multivariable logistic regression to identify independent sociodemographic and substance use-related correlates of any form of drug treatment engagement after an overdose among 179 PWID who had overdosed in the past 6 months. RESULTS One-third of our sample (33.0%) started any form of drug treatment in the 30 days following their most recent overdose. Factors associated with engaging in drug treatment included: recent buprenorphine or Suboxone injection (aOR: 2.39, 95% CI: 1.15, 4.96), someone calling 911 after their most recent overdose (aOR: 3.29, 95% CI: 1.63, 6.65), and older age (aOR per year of age: 0.95, 95% CI: 0.91, 0.99). CONCLUSIONS Our results suggest that contact with emergency personnel after an overdose may represent an important opportunity to link PWID to drug treatment. The implementation of response teams trained in linking PWID to the services they require and helping persons navigate treatment systems maybe be a valuable intervention to reduce the harms of the opioid overdose crisis.

Abstract
Aim Experiencing a nonfatal overdose (NFOD) is a significant risk factor for a subsequent nonfatal or fatal overdose. Overdose mortality rates in rural Appalachian states are some of the highest in the USA, but little is known about correlates of overdose among rural populations of people who inject drugs (PWID). Our study aimed to identify correlates of experiencing a recent (past 6 months) NFOD among rural PWID in Cabell County, West Virginia. Methods Using data from a June–July 2018 cross-sectional survey that was designed to estimate the size and characteristics of the PWID population in Cabell County, West Virginia, we used log binomial regression to identify correlates (e.g., structural vulnerabilities and substance use) of NFOD in the past 6 months. Results The majority of our sample of 420 PWID were male (61.2%), White, non-Hispanic (83.6%), and reported recent heroin injection (81.0%). More than two-fifths (42.6%) experienced a recent NFOD. Independent correlates of NFOD included witnessing an overdose in the past 6 months (adjusted prevalence ratio [aPR] = 2.28; 95% CI 1.48–3.50), attempting to quit using drugs in the past 6 months (aPR = 1.54; 95% CI 1.11–2.14), and the number of drugs injected (aPR = 1.16; 95% CI 1.10–1.23) Conclusions A large proportion of rural PWID in Appalachia reported having recently overdosed. The associations between witnessing an overdose, attempting to quit using drugs, and number of drugs injected with recent nonfatal overdose underscore the need for expanded access to overdose prevention resources that are tailored to the needs of this population. Expanding access to evidence-based overdose prevention strategies—such as take-home naloxone programs, treatment with methadone or buprenorphine, and harm reduction services—may decrease overdose morbidity and mortality among rural PWID in Appalachia.

Drug Alcohol Depend 2021; 218:108419. [PMID: 33296857 PMCID: PMC7759029 DOI: 10.1016/j.drugalcdep.2020.108419] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/28/2020] [Revised: 09/25/2020] [Accepted: 10/31/2020] [Indexed: 12/13/2022]
Abstract
BACKGROUND As opioid overdoses and deaths increase globally, little is known about these dimensions in Sub-Saharan Africa. In this paper, we explore factors associated with opioid overdose experiences among a sample of women who use opioids in Dar es Salaam, Tanzania. METHODS We conducted a cross-sectional survey with 200 women who use opioids in Dar es Salaam, Tanzania, recruited via respondent-driven sampling. We fitted unadjusted and adjusted log-binomial regression models with robust standard errors to examine associations between participant characteristics and reporting ever had an opioid overdose in terms of prevalence ratios. RESULTS Thirty-four percent (n = 68) of participants reported having ever had an opioid overdose. In the final adjusted model, having ever attempted to stop using heroin (adj. PR = 1.46, 95% CI: 1.01-2.12), sleeping outside in the past 6 months (adj. PR = 1.93, 95% CI: 1.29-2.91), injecting drugs (adj. PR = 1.78, 95% CI: 1.19-2.66), alcohol use (adj. PR = 1.56, 95% CI: 1.09-2.23), and having moderately severe to severe depression (adj. PR = 3.10, 95% CI: 1.07-8.97) were all found to be significantly associated with having ever had an opioid overdose. CONCLUSIONS We demonstrate factors associated with opioid overdose among women who use drugs in Tanzania that may not be addressed with injection-focused harm reduction efforts. Our findings suggest the need for overdose surveillance efforts and further work to characterize overdose risks in this context in order to design relevant, targeted interventions to prevent opioid overdose in sub-Saharan Africa.

Abstract
BACKGROUND To examine, among a cohort of opioid dependent people with a history of opioid agonist treatment (OAT), the frequency and incidence rates of non-fatal overdose (NFOD) hospital separations over time, by age and sex. METHODS Retrospective cohort study of people with a history of OAT using state-wide linked New South Wales (NSW) data. The incidence of NFOD hospital separations involving an opioid, sedative, stimulant or alcohol was defined according to the singular or combination of poisoning/toxic effect using ICD-10-AM codes. Crude incidence rates were calculated by gender, age group and calendar year. RESULTS There were 31.8 (31.3-32.3) NFOD per 1,000 person-years (PY). Opioid NFOD incidence was higher in women than men: incidence rate ratio (IRR) 1.11 per 1,000PY; 95 %CI: [1.06-1.17]; women had higher sedative NFOD rates than men, IRR 1.27 per 1,000PY [1.21-1.34]. Participants ≤25 years, 26-30yrs, and 31-35yrs had higher incidence of opioid NFOD compared to 46+yrs, with IRRs of: 1.45 per 1,000PY; [1.32-1.59]; 1.20 per 1,000PY; [1.11-1.30] and 1.22 per 1,000PY; [1.13-1.32], respectively. Between 2006-7 and 2016-17, the cohort accounted for 19 % of NSW opioid NFOD episodes, 12 % of sedative, 14 % of stimulant and 5 % of acute alcohol-related NFOD. CONCLUSIONS Hospital stays due to NFOD are a relatively frequent occurrence among opioid-dependent people. There are clear differences in rates and substances involved by sex, age and over time. Evidence-based interventions that prevent overdose among people who are opioid dependent need to be delivered to scale, including widespread community provision of naloxone.

Abstract
INTRODUCTION Heroin overdose is a leading cause of mortality among drug users. This paper aims to identify individual and contextual factors associated with lethal and non-lethal heroin-related overdoses on the basis of case reports and semi-structured proxy interviews. Typical patterns within these cases are determined by means of cluster analysis. METHODS Within the CaRe (Case Reports of heroin-related overdoses) study, case reports (100 proxy reports of overdose events from 36 different facilities) were gathered and evaluated as part of a nationwide survey of experts conducted in Germany in 2019. Following initial descriptive analyses a two-step cluster analysis with the four binary variables of gender, age, time and place was conducted to identify patterns within the reported cases. RESULTS The case reports grouped into five clusters: 1) Younger male drug users, found in a public space during the daytime; 2) Female drug users; 3) Older male drug users, found in a public space during the daytime; 4) Drug users found at home at night; 5) Drug users found outside at night. Overdoses by female drug users and those which occurred at home and/or at night were significantly more likely to have a fatal outcome. CONCLUSION Future prevention and intervention measures should aim to consider the context, i.e. typical constellations of risk, and attempt to inhibit this through appropriate counter measures.

Abstract
BACKGROUND Poisoning is one of the leading causes of admission to the emergency department and intensive care unit. A large number of epidemiological changes have occurred over the last years such as the exponential growth of new synthetic psychoactive substances. Major progress has also been made in analytical screening and assays, enabling the clinicians to rapidly obtain a definite diagnosis. METHODS A committee composed of 30 experts from five scientific societies, the Société de Réanimation de Langue Française (SRLF), the Société Française de Médecine d'Urgence (SFMU), the Société de Toxicologie Clinique (STC), the Société Française de Toxicologie Analytique (SFTA) and the Groupe Francophone de Réanimation et d'Urgences Pédiatriques (GFRUP) evaluated eight fields: (1) severity assessment and initial triage; (2) diagnostic approach and role of toxicological analyses; (3) supportive care; (4) decontamination; (5) elimination enhancement; (6) place of antidotes; (7) specificities related to recreational drug poisoning; and (8) characteristics of cardiotoxicant poisoning. Population, Intervention, Comparison, and Outcome (PICO) questions were reviewed and updated as needed, and evidence profiles were generated. Analysis of the literature and formulation of recommendations were then conducted according to the GRADE® methodology. RESULTS The SRLF-SFMU guideline panel provided 41 statements concerning the management of pharmaceutical and recreational drug poisoning. Ethanol and chemical poisoning were excluded from the scope of these recommendations. After two rounds of discussion and various amendments, a strong consensus was reached for all recommendations. Six of these recommendations had a high level of evidence (GRADE 1±) and six had a low level of evidence (GRADE 2±). Twenty-nine recommendations were in the form of expert opinion recommendations due to the low evidences in the literature. CONCLUSIONS The experts reached a substantial consensus for several strong recommendations for optimal management of pharmaceutical and recreational drug poisoning, mainly regarding the conditions and effectiveness of naloxone and N-acetylcystein as antidotes to treat opioid and acetaminophen poisoning, respectively.

Supervised consumption service use and recent non-fatal overdose among people who inject drugs in Toronto, Canada. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2020; 87:102993. [PMID: 33160158 DOI: 10.1016/j.drugpo.2020.102993] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2020] [Revised: 08/21/2020] [Accepted: 09/29/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND Aiming to reducing overdose mortality, over 40 supervised drug consumption services (SCS) presently operate in Canada. Arguments against SCS include the potential for increased non-fatal overdoses mediated by risk compensation. This study estimates associations between SCS use and recent non-fatal overdose among people who inject drugs (PWID). METHODS We analyzed cross-sectional baseline data collected between November 2018 and March 2020 from a cohort of adult PWID in Toronto, Canada. Recent non-fatal overdose was self-reported over the previous six months. The primary exposure was frequency of SCS use, self-reported as the proportion of injections performed at an SCS (all or most [75-100%], some [26-74%], few [≤25%], or none) in the previous six months. The prevalence of recent overdose was compared between all unique pairs of groups based on their frequency of SCS use and expressed as covariate-adjusted prevalence ratios (PR) estimated using modified Poisson regression. RESULTS Among 701 PWID (median [IQR] age, 40 [33 to 49]; 64.3% cisgender men; 56.8% injecting daily), most reported SCS use (all/most, 26.2%; some, 30.9%; few, 29.4%) versus no use (13.5%), with 38.6% reporting a recent overdose. From adjusted regression analyses, more frequent SCS use was not statistically significantly associated with overdose when compared to either no SCS use or less frequent use. Associations between SCS use frequency and overdose were notably smaller among SCS clients compared to associations between SCS clients and non-users (e.g., all/most versus none: PR, 1.43 [95% CI, 0.93 to 2.21]; all/most versus some: PR, 0.94 [95% CI, 0.75 to 1.17]; all/most versus few: PR, 1.15 [95% CI, 0.89 to 1.48]). CONCLUSION Findings did not indicate statistically significant associations between SCS use frequency and recent non-fatal overdose, particularly among SCS clients who may be more comparable. Nevertheless, overdose was common, underscoring the need to prevent non-fatal overdose and associated morbidity.

[PMID: 32929594 PMCID: PMC7578170 DOI: 10.1007/s00414-020-02412-y] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2020] [Accepted: 08/27/2020] [Indexed: 12/12/2022]
Abstract
AIMS The primary objective of this study was to investigate whether the fatalities of opioid abuse are not only related to respiratory depression but also as a result of other side effects such as emesis, delayed gastric emptying, a reduction of the cough reflex, and impaired consciousness leading to the aspiration of gastric contents, a finding regularly observed in drug-related deaths. DESIGN A retrospective exploratory study analyzing heroin/morphine/methadone-related deaths submitted to court-ordered autopsy. SETTING Center for Forensic Medicine, Medical University of Vienna, Austria (2010-2015). PARTICIPANTS Two hundred thirty-four autopsy cases were included in the study: morphine (n = 200), heroin (n = 11), and methadone (n = 23) intoxication. FINDINGS Analyses revealed that 41.88% of all deceased showed aspiration of gastric contents with equal gender distribution (p = 0.59). Aspiration was more frequent in younger deceased (χ2 = 8.7936; p = 0.012) and in deceased with higher body mass index (BMI) (χ2 = 6.2441; p = 0.044). Blood opioid concentration was lower in deceased with signs of aspiration than in non-aspirators (p = 0.013). Toxicological evaluation revealed a high degree of concomitant substance abuse (91%)-benzodiazepines (61.6%) and/or alcohol (21.8%). CONCLUSIONS There are lower opioid concentrations in deceased with signs of aspiration, a fact which strongly points to aspiration as alternative cause of death in opioid-related fatalities. Furthermore, this study highlights the common abuse of slow-release oral morphine in Vienna and discusses alternative medications in substitution programs (buprenorphine/naloxone or tamper-resistant slow-release oral morphine preparations), as they might reduce intravenous abuse and opioid-related deaths.

Abstract
BACKGROUND Heroin dependence is a complex disease with multiple phenotypes. Classification of heroin users into more homogeneous subgroups on the basis of these phenotypes could help to identify the involved genetic factors and precise treatments. This study aimed to identify the association between genetic polymorphisms of DA synthesis and metabolism genes, including tyrosine hydroxylase (TH), DOPA decarboxylase (DDC), solute carrier family 6 member 3 (SLC6A3) and DA beta-hydroxylase (DBH), with six important phenotypes of heroin dependence. METHODS A total of 801 heroin dependent patients were recruited and fourteen potential functional single nucleotide polymorphisms (SNPs) were genotyped by SNaPshot. Associations between SNPs with six phenotypes were mainly assessed by binary logistic regression. Generalized multifactor dimensionality reduction was used to analyze the gene-by-gene and gene-by-environment interactions. RESULTS We found that DBH rs1611114 TT genotype had a protective effect on memory impairment after heroin dependence (P = 0.002, OR = 0.610). We also found that the income-rs12666409-rs129915-rs1611114 interaction yielded the highest testing balance accuracy and cross-validation consistency for memory change after heroin dependence. CONCLUSIONS Our results suggest that the memory change after heroin dependence was a result of a combination of genetics and environment. This finding could lead to a better understanding of heroin dependence and further improve personalized treatment.

Abstract
Opioids are arguably one of the most important pharmacologic classes, mainly due to their rich history, their useful and potent analgesic effects, and also, just as importantly, their "Dark Side", constituted by their reinforcing properties that have led countless of users to a spiral of addiction, biological dependence, tolerance, withdrawal syndromes, and death. Among the most significant abused and addictive known opioids are heroin and desomorphine, both synthetic derivatives of morphine that belong to the 4,5-epoxymorphinan structural chemical group of the opioid family drugs. These agents share not only structural, pharmacological, and epidemiological features but also a common geographical distribution. A drop in Afghan heroin production and its "exports" to Russia gave rise to widespread consumption of desomorphine in ex-Soviet republics during the first decade of the 21st century, representing an economical and accessible alternative for misusers to this sort of derivative. Herein we review the state of the art of history, chemistry and synthesis, pharmacology, and impact on society of these "cursed cousins".

Abstract
BACKGROUND Adolescent drug use has long term health consequences, like substance use disorders and psychiatric illnesses. Proximal health risks, especially for overdose, are amplified when multiple substances are combined. Existing literature on polysubstance use among adolescents has largely focused on alcohol, tobacco, and marijuana, but has largely excluded other drugs like opioids. Understanding how adolescents combine illicit drugs is essential for intervening to prevent poor health outcomes. METHODS We aimed to explore patterns of lifetime polysubstance use among adolescents in Baltimore City. We used data on 9th-12th graders recruited to participate in the 2017 local Baltimore Youth Risk Behavior Survey who reported any lifetime drug use (n = 387; 60 % female, 77 % non-Hispanic Black). We then conducted a latent class analysis using 10 indicators of lifetime drug and alcohol use. After selecting the class model, we tested for associations between the class profiles and race, sex, school grade, and lifetime injection drug use. RESULTS We identified three profiles of lifetime polysubstance use in our sample: alcohol and marijuana (68.6 % of sample), polysubstance (22.0 %), and alcohol/pain medication/inhalant use (9.4 %). Members of the polysubstance use class were more likely to be male and to report injection drug use. CONCLUSIONS Understanding broader patterns of drug use beyond alcohol, tobacco and marijuana among adolescents is a crucial step towards preventing adverse drug and health-related outcomes later in life. More research is needed to characterize the full health impact of youth polysubstance use patterns and related risk behaviors like injection drug use.

Abstract
The use of pharmacological treatments for opioid use disorders, including methadone, buprenorphine and naltrexone has been associated with a reduction in mortality compared with illicit opioid use. However, these treatments can also contribute significantly to the risk of death. The opioid agonists methadone and buprenorphine achieve clinical efficacy in patients with an opioid use disorder through suppressing craving and diminishing the effectiveness of illicit opioid doses, while the antagonist naltrexone blocks the action of opioids. Pharmacological differences between opioid pharmacotherapies then create different temporal patterns of protection and mortality risk, different risks of relapse to illicit opioid use, and variations in direct and indirect toxicity, which are revealed in clinical and epidemiological studies. Induction onto methadone and the cessation of oral naltrexone treatment are associated with an elevated risk of opioid poisoning, which is not apparent in patients treated with buprenorphine or sustained-release naltrexone. Beyond drug-related mortality, these pharmacotherapies can impact a participant's risk of death. Buprenorphine may also have some advantages over methadone in patients with depressive disorders or cardiovascular abnormalities. Naltrexone, which is also commonly prescribed to manage problem alcohol use, may reduce deaths in chronic co-alcohol users. Understanding these pharmacologically driven patterns then guides the judicious choice of drug and dosing schedule and the proactive risk management that is crucial to minimising the risk of death in treatment.

Abstract
INTRODUCTION Opioid overdose emergencies are increasing every year, naloxone is the antidote for the treatment of opioid overdose. Naloxone is being dispensed to even lay persons through some programs to prevent opioid overdose deaths. CASE 23 year old patient presented with naloxone treated opioid overdose complained of chest pain, pink frothy sputum production and shortness of breath. Physical exam showed tachycardia, tachypnea and coarse breath sounds. Imaging of the lungs showed diffuse pulmonary edema. Within an hour after the administration of naloxone patient developed pulmonary edema and lung injury. Patient was managed with non-invasive positive pressure ventilation which improved patient's symptoms in less than 6 hours confirmed by radiological improvement in 24-36 hrs. DISCUSSION There are no specific observation guidelines post naloxone treatment in opiate overdose patients. We recommend early treatment of naloxone induced pulmonary complications during the observation period with non-invasive positive pressure ventilation to reduce the morbidity.

Abstract
Cognitive impairment is common in persons with opioid use disorder and associated with poor treatment outcomes, including elevated risk for relapse. Much less is known about the underlying structure of these deficits and the possible presence of cognitive phenotypes. A total of 177 adults (average 42.2 years of age, 52.0% male, 65.5% Caucasian) enrolled in a methadone maintenance treatment program completed the NIH Toolbox as part of a larger project. Cluster analyses revealed a 2-cluster solution-persons with intact cognitive function in all domains (n = 93; Intact) and those with impairments on tests of attention and executive function (n = 83; Impaired). Follow-up analyses revealed that the Impaired group was slightly older, more likely to self-identify as a racial/ethnic minority, and less likely to report consuming alcohol four or more times per week. These findings suggest the existence of distinct cognitive profiles in persons with opioid use disorder and encourage further examination, particularly studies to examine the possible benefits of routine screening for cognitive impairment as part of substance use treatment.

The effectiveness of drug-related Good Samaritan laws: A review of the literature. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2020; 90:102773.

Abstract
BACKGROUND The United States (US) and Canada are in the midst of an opioid overdose epidemic. Many people who use illicit drugs (PWUD) do not call an emergency number 911 at the scene of an overdose due to fear of arrest. In the US and Canada, when an individual calls 911, both emergency medical services (EMS) and police are notified to attend the overdose event. In response, many settings in North America have introduced drug-related 'Good Samaritan' laws (GSLs) that aim to encourage PWUD to call 911 by providing legal immunity (mainly protections from drugs possessed for personal use) to those at the scene of the overdose. However, little is known about the effectiveness of these laws in increasing calls to 911. METHODS We conducted a literature review of the published literature between 2005 and 2019 to examine the effectiveness of GSLs. Searches were referenced using keywords that included: "good samaritan", "overdose", "emergency services", and "drug use". RESULTS Among 68 articles identified, after eligibility screening, 12 publications were deemed to meet the inclusion criteria. These publications were largely quantitative observational studies (9/12), with a minority (3/12) being qualitative in design. Two major themes emerged: "knowledge of GSLs and calling EMS" and "overdose-related hospital admissions and mortality assessment". CONCLUSION At this time, the current body of evidence regarding the effectiveness of GSLs in increasing calls to EMS and reducing drug-related harms is limited and mixed. Studies show that PWUD have low levels of knowledge regarding GSLs while some evidence suggests their effectiveness in increasing calls to EMS at the scene of an overdose. Given the current overdose crisis, further investigation is warranted to establish the effectiveness of these laws in reducing drug-related harms.

Abstract
We are sadly experiencing unprecedented levels of overdose mortalities attributed to the increased availability of synthetic opioids in illegal markets. While the majority of attention in North America has focused on preventing drug overdose cases through the distribution and administration of naloxone, in addition to stricter regulations of opioid prescriptions and greater law enforcement in illegal markets, little attention has been given to other alternative models and treatments for people who use drugs that are tailored specifically to the health care needs of this marginalized population. Through this analysis, the implications of task-shifting in health care via the distribution of naloxone for an already marginalized population are discussed. Alternatively, the role of pioneering harm-reduction programs - such as supervised injection/consumption sites, a variety of opioids maintenance therapies, and social-structural interventions - are highlighted as crucial interventions in the current ongoing opioid crisis. Moreover, people with lived experiences of illegal drug use are discussed as having a pivotal role but being ultimately overshadowed by public health partners.

Abstract
BACKGROUND New Hampshire (NH) has had among the highest rates of fentanyl-related overdose deaths per capita in the United States for several years in a row-more than three times the national average in 2016. This mixed-methods study investigated drug-using practices and perspectives of NH residents who use opioids to inform policy in tackling the overdose crisis. METHODS Seventy-six participants from six NH counties completed demographic surveys and semi-structured interviews focused on drug-using practices and perspectives, including use precursors, fentanyl-seeking behaviors, and experiences with overdose. Rigorous qualitative methods were used to analyze interview data including transcription, coding and content analysis. Descriptive statistics were calculated on quantitative survey data. RESULTS Eighty-four percent of interviewees had knowingly used fentanyl in their lifetime, 70 % reported overdosing at least once, and 42 % had sought a batch of drugs known to have caused an overdose. The majority stated most heroin available in NH was laced with fentanyl and acknowledged that variability across batches increased overdose risk. Participants reported high availability of fentanyl and limited access to prevention, treatment, and harm reduction programs. There was widespread support for expanding education campaigns for youth, increasing treatment availability, and implementing needle exchange programs. CONCLUSIONS A confluence of factors contribute to the NH opioid overdose crisis. Despite consensus that fentanyl is the primary cause of overdoses, individuals continue to use it and affirm limited availability of resources to address the problem. Policies targeting innovative prevention, harm reduction, and treatment efforts are needed to more effectively address the crisis.

Abstract
Background Opioid-related deaths have increased in Western countries over recent decades. Despite numerous studies investigating opioid-related mortality, only a few have focused on the lives of the deceased individuals prior to their deaths, specifically regarding contact with care-providing authorities such as health, social and correctional services. Furthermore, a change has been noted in the last two decades as to which opioids cause most deaths, from heroin to prescription opioids. However, studies comparing fatalities caused by different substances are rare. The aim of this study was to investigate contact with care-providing authorities during the year prior to death among individuals who died as a result of opioid intoxication and to analyse differences relating to which opioids caused their deaths. Methods The study is based on retrospective register data and includes 180 individuals with a history of illicit drug use, who died from opioid intoxication in Skåne, Sweden, between 1 January 2012 to 31 December 2013 and 1 July 2014 to 30 June 2016. Intoxications caused by heroin, methadone, buprenorphine and fentanyl were included. Data were collected from the National Board of Forensic Medicine, regional health care services, municipal social services and the Prison and Probation Service. Statistical testing was performed using Pearson’s chi-square test, Fisher’s exact test and the Mann-Whitney U test to analyse group differences. Results A total of 89% of the deceased individuals had been in contact with one or more of the care-providing authorities during the year prior to death; 75% had been in contact with health care, 69% with the social services, 28% with the Prison and Probation Service, and 23% had been enrolled in opioid substitution treatment at some point during their final year of life. Few differences appeared between the substance groups with regard to which opioid contributed to the death. In addition to opioids, sedatives were present in more than 80% of the cases. Individuals whose deaths were buprenorphine-related had been in contact with the social services to a significantly lesser extent during the year prior to death. Conclusions The studied population is characterised by extensive contact with care-providing authorities, thus providing numerous opportunities for authorities to reach this group with preventive and other interventions. Few differences emerged between groups with regard to which opioid had contributed to the death.

Abstract
BACKGROUND Adults released from prison are at increased risk of poor health outcomes and preventable mortality, including from overdose. Non-fatal overdose (NFOD) is a strong predictor of future overdose and associated with considerable morbidity. This study aims to the determine the incidence, predictors and clinical characteristics of NFOD following release from prison. METHODS We used pre-release interview data collected for a randomised controlled trial in 2008-2010, and linked person-level, state-wide ambulance, emergency department, and hospital records, from a representative sample of 1307 adults incarcerated in Queensland, Australia. The incidence of NFOD following release from prison was calculated. A multivariate Andersen-Gill model was used to identify demographic, health, social, and criminal justice predictors of NFOD. RESULTS The crude incidence rate (IR) of NFOD was 47.6 (95%CI 41.1-55.0) per 1000 person-years and was highest in the first 14 days after release from prison (IR = 296 per 1000 person-years, 95%CI 206-426). In multivariate analyses, NFOD after release from prison was positively associated with a recent history of substance use disorder (SUD), dual diagnosis of mental illness and SUD, lifetime history of injecting drug use, lifetime history of NFOD, being dispensed benzodiazepines after release, a shorter index incarceration, and low perceived social support. The risk of NFOD was lower for people with high-risk alcohol use and while incarcerated. CONCLUSIONS Adults released from prison are at high risk of non-fatal overdose, particularly in the first 14 days after release. Providing coordinated transitional care between prison and the community is likely critical to reduce the risk of overdose.
