Abstract
The opioid and cannabinoid receptor systems are inextricably linked-overlapping at the anatomical, functional and behavioural levels. Preclinical studies have reported that cannabinoid and opioid agonists produce synergistic antinociceptive effects. Still, there are no experimental data on the effects of cannabinoid agonists among humans who receive opioid agonist therapies for opioid use disorder (OUD). We conducted an experimental study to investigate the acute effects of the delta-9-tetrahydrocannabinol (THC) among persons receiving methadone therapy for OUD. Using a within-subject, crossover, human laboratory design, 25 persons on methadone therapy for OUD (24% women) were randomly assigned to receive single oral doses of THC (10 or 20 mg, administered as dronabinol) or placebo, during three separate 5-h test sessions. Measures of experimental and self-reported pain sensitivity, abuse potential, cognitive performance and physiological effects were collected. Mixed-effects models examined the main effects of THC dose and interactions between THC (10 and 20 mg) and methadone doses (low-dose methadone defined as <90 mg/day; high dose defined as >90 mg/day). Results demonstrated that, for self-reported rather than experimental pain sensitivity measures, 10 mg THC provided greater relief than 20 mg THC, with no substantial evidence of abuse potential, and inconsistent dose-dependent cognitive adverse effects. There was no indication of any interaction between THC and methadone doses. Collectively, these results provide valuable insights for future studies aiming to evaluate the risk-benefit profile of cannabinoids to relieve pain among individuals receiving opioid agonist therapy for OUD, a timely endeavour amidst the opioid crisis.

Abstract
BACKGROUND Patient satisfaction is key to the success of methadone maintenance treatment (MMT), and yet how MMT satisfaction is affected by the increasingly common use of crystal methamphetamine among people receiving opioid treatment remains poorly understood. We aimed to assess the association between crystal methamphetamine use and MMT dissatisfaction. METHODS We employed generalized estimating equations to examine the relationship between crystal methamphetamine use and MMT dissatisfaction among patients receiving MMT within two prospective cohorts in Vancouver, Canada, between December 2016 and March 2020. RESULTS Of the 836 participants receiving MMT, the median age was 47 years, and 55.3 % self-identified as male at baseline. In a multivariable model, those reporting more than weekly crystal methamphetamine use were more likely to report MMT dissatisfaction (Odds ratio: 1.40, 95 % confidence interval: 1.05-1.86) compared to those reporting less than monthly crystal methamphetamine use. CONCLUSIONS Among our sample of people receiving MMT, we noted a positive association of frequent crystal methamphetamine use with MMT dissatisfaction. Our study suggests a need for novel strategies to better understand and address frequent methamphetamine use among those receiving MMT, particularly given recent shifts in substance use patterns involving the rising co-use of methamphetamines and opioids.

Abstract
BACKGROUND Physical diseases represent a significant burden for opioid agonist treatment (OAT) patients. This study described physical morbidity in two national cohorts of OAT patients focusing on gender differences. METHODS This population-based cohort study linking multiple health registers investigated physical diseases (ICD-10) in patients receiving OAT in the Czech Republic (N = 4,280) and Norway (N = 11,389) during 2010-2019. Gender-stratified analysis was performed. RESULTS Overall, we found a large burden of physical morbidity across gender groups in OAT patients. In the Czech Republic and Norway, women in OAT had a significantly higher prevalence of physical diseases across most diagnostic chapters, notably genitourinary diseases and neoplasms. Injuries/external causes and infectious/parasitic diseases were among the most common diseases in both women and men. Viral hepatitis accounted for over half of infectious morbidity in women and men in both cohorts. CONCLUSIONS Our findings support the need for early screening, detection, and treatment of diseases and conditions across organ systems and the integration of health promotion activities to reduce physical morbidity in OAT patients. The gender differences underline the need for a tailored approach to address specific medical conditions.

Abstract
BACKGROUND Patients receiving buprenorphine for the treatment of opioid use disorder (OUD) experience a roughly 50% reduction in mortality risk relative to those not receiving medication. Longer periods of treatment are also associated with improved clinical outcomes. Despite this, patients often express desires to discontinue treatment and some view taper as treatment success. Little is known about the beliefs and medication perspectives of patients engaged in long-term buprenorphine treatment that may underlie motivations to discontinue. METHODS This study was conducted at the VA Portland Health Care System (2019-2020). Qualitative interviews were conducted with participants prescribed buprenorphine for ≥2 years. Coding and analysis were guided by directed qualitative content analysis. RESULTS Fourteen patients engaged in office-based buprenorphine treatment completed interviews. While patients expressed strong enthusiasm for buprenorphine as a medication, the majority expressed the desire to discontinue, including patients actively tapering. Motivations to discontinue fell into 4 categories. First, patients were troubled by perceived side effects of the medication, including effects on sleep, emotion, and memory. Second, patients expressed unhappiness with being "dependent" on buprenorphine, framed in opposition to personal strength/independence. Third, patients expressed stigmatized beliefs about buprenorphine, describing it as "illicit," and associated with past drug use. Finally, patients expressed fears about buprenorphine unknowns, including potential long-term health effects and interactions with medications required for surgery. CONCLUSIONS Despite recognizing benefits, many patients engaged in long-term buprenorphine treatment express a desire to discontinue. Findings from this study may help clinicians anticipate patient concerns and can be used to inform shared decision-making conversations regarding buprenorphine treatment duration.

Abstract
INTRODUCTION Patient satisfaction is a critical measure of quality of care across health disciplines because it may affect clinical outcomes. OBJECTIVES This study aimed to examine longitudinal patient satisfaction in individuals with opioid use disorder (OUD) randomized to receive either standard methadone or flexible buprenorphine/naloxone models of care, its predictors, and association with dropout/illicit drug use. METHODS This study assessed patient satisfaction, using the 8-item version of the Client Satisfaction Questionnaire (CSQ), as a secondary outcome of a large phase IV pragmatic randomized controlled trial (OPTIMA). The effectiveness of standard methadone model of care was compared with flexible take-home buprenorphine/naloxone dispensation model of care in patients with prescription-type OUD. Of 272 participants recruited and followed up for 24 weeks, 183 were eligible for this study. RESULTS Throughout the study, patients were "satisfied" with their treatment. The average CSQ score was not significantly different between weeks 4, 12, and 24 in the total sample (χ 2 = 0.35; P = 0.84). There was no significant difference in CSQ based on treatment assignment (methadone vs flexible buprenorphine/naloxone) either overall ( z = 0.87; P = 0.38) or over time (χ 2 = 0.65; P = 0.72). High levels of depression at baseline and decreased depressive symptoms over the follow-up period predicted positive changes in patient satisfaction ( P = 0.03 and P = <0.01, respectively). Satisfaction was significantly associated with treatment retention but not illicit drug use. CONCLUSIONS This study demonstrates that patients with OUD on either standard methadone or flexible buprenorphine were generally satisfied with their treatment, with no difference in patient satisfaction based on treatment allocation. Given the ongoing opioid crisis, strategies to improve patient satisfaction should be further explored.

Abstract
Previous studies have indicated elevated levels of impulsivity, hyperactivity, and inattention (IHI) among opioid-dependent patients seeking outpatient treatment with extended-release naltrexone (XR-NTX). This led us to hypothesize that IHI may be associated with a higher discontinuation rate for XR-NTX treatment. In a group of 162 patients with opioid dependence, discontinuation prior to the full 24 weeks of the study period (six injections and attending the study visit at 24 weeks) occurred in 49% of the patients, primarily in the early stage of treatment. IHI above the clinical cut-off on the adult ADHD self-report scale (ASRS) was not associated with a risk of premature discontinuation. This finding was not altered when controlling for socio-demographics, substance, use and mental health severity. Conclusively, high levels of IHI per se is not contradictive for XR-NTX treatment in regard to concern for premature discontinuation.

Abstract
Abstract
Background
The aim of this study was to comparing the complications (depression, anxiety, sleep disorders and sexual dysfunction) of buprenorphine, methadone and opium tincture as an alternative drug treatment in patients referred to the National Center for Addiction Studies of Tehran during 2020–2021. This cross-sectional study was concocted on 197 patients referred to the National Center for Addiction Studies of Tehran who were treated with one of the alternative treatments of opioids buprenorphine (n = 24), methadone (n = 116), and opium tincture (n = 57) during 2020–2021. Three questionnaires were used to assess the side effects of drugs including Anxiety and Depression Hospital Scales (HADS), AIS (Athens insomnia scale) and the International Index of Erectile Function (IIEF). Data were analyzed using Stata 14.0. The multinomial logistic regression model was used in order to compare complications in the three groups and adjusted odds ratio (OR) with 95% confidence interval (CI) were estimated.
Results
The mean age in the buprenorphine, methadone and opium tincture groups were 46.80 ± 9.90, 48.31 ± 13.33 and 55.30 ± 10.34 years, respectively. The numbers of men were 17 (70.80), 90 (77.60), and 50 (78.70); respectively. Multinomial logistic regression model showed OR = 0.73 (95% CI 0.61–0.88) for anxiety in the methadone group in compared to buprenorphine. Likewise, OR = 1.22 (95% CI 1.001–1.48) and OR = 1.34 (95% CI 1.10–1.63) was observed for sleep disorder in the methadone and opium tincture groups in compared to buprenorphine; respectively.
Conclusions
Sleep disturbance in buprenorphine group is less than opium tincture and methadone. Also, anxiety in the methadone group was lower than the buprenorphine, however, there was no significant difference between the three groups in term of sexual function and depression. In addition to control measures for sleep disorders in receiving methadone and buprenorphine, the cohort studies with a higher sample size are recommended.

Abstract
Abstract
Background
The resurgence of heroin use and the misuse of pharmaceutical opioids are some of the reasons for a worldwide increase in opioid dependence. Opioid Medication Therapies (OMT) have amply demonstrated their efficacy. From a medical point of view, the main objectives of OMT concern medical and social outcomes, centred on risk reduction and the cessation of opioid use. But patient points of view can differ and few studies have explored opioid-dependent patient viewpoints on their OMT. This variable seems important to consider in a patient-centred approach. The aim of our study was to explore points of view of people who use drugs (PWUD) treated with OMT, in a large multicentre sample.
Method
A cross-sectional multicentre study explored the points of view of PWUD with Opioid Use Disorder following OMT. Data regarding the patients’ points of view were collected using a self-administered questionnaire developed by the scientific committee of the study. A descriptive analysis and an exploratory factor analysis were performed to explore the structure of items exploring patient viewpoints.
Results
263 opioid dependent PWUD were included, a majority were men consuming heroin prior to being prescribed OMT. 68% were on methadone, 32% were on buprenorphine. Most PWUD identified a positive impact on their lives, with 92.8% agreeing or strongly agreeing that OMT had changed a lot of things in their lives. The exploratory factor analysis identified three factors: (F1) items related to points of views concerning the objectives and efficacy of OMT; (F2) items related to the legitimacy of OMT as a treatment compared to a drug, (F3) items related to experiences and relationships with OMT.
Conclusion
Patient viewpoints on efficacy were correlated with the pharmacological benefits of OMT and with the associated psychosocial measures. The implications of OMT in relationships, such as the feeling of being judged, concerned a majority. Points of view were ambivalent concerning the role of OMT as a treatment or as a drug. Involving patient points of view in therapeutic strategies decisions could help enhance positive views among PWUD on OMT and help PWUD towards their recovery.
Trial registration: OPAL study was registered: (NCT01847729).

Abstract
The level of impulsivity, hyperactivity, and inattention (IHI) is higher among patients with substance use disorder (SUD) than in the general population. However, the prevalence of such symptoms in patients seeking treatment with an opioid antagonist, such as extended-release naltrexone (XR-NTX), is unknown. We screened 162 patients with opioid use disorder (OUD) seeking treatment with XR-NTX in Norway using the Adult ADHD Self-Report Scale (ASRS) to estimate the prevalence of IHI alongside an assessment of mental and physical health and substance use. Sixty-six patients scored above the clinical cut-off on the ASRS. Higher levels of IHI were significantly associated with a longer history of frequent amphetamine use, current alcohol use, and greater mental distress. Mental distress was the strongest factor associated with higher levels of IHI. The introduction of screening for IHI and mental distress in opioid maintenance treatment and XR-NTX would likely improve the quality of care and enable clinicians to tailor interventions to the needs of patients with high levels of IHI to prevent treatment discontinuation.

Abstract
OBJECTIVES Alternative transition protocols from methadone to buprenorphine in the treatment of opioid use disorder (OUD) are needed to reduce the risk of precipitated withdrawal and opioid use during induction. METHODS Case report (n = 1). RESULTS One patient with OUD underwent a rapid microinduction outpatient protocol that did not cause precipitated withdrawal or require preceding taper before cessation of methadone. The induction was carried out safely in the outpatient setting. CONCLUSIONS This report provides a patient-centered approach demonstrating feasibility and cost-effectiveness of rapid transition to buprenorphine in the US outpatient psychiatry setting. Barriers to adherence to opioid agonist therapy may be reduced using this protocol.

Abstract
BACKGROUND There is little evidence-based guidance on how to optimize methadone dosages among patients with opioid addiction undergoing methadone maintenance treatment (MMT). This study aims to investigate whether self-perceived opioid withdrawal symptoms, adverse effects, and self-reported substance use in patients on MMT are related to serum methadone concentrations and the role that these variables could play in clinical decisions on dose adjustments. METHODS This naturalistic prospective cohort study included clinical and laboratory measurements from 83 patients undergoing MMT in outpatient clinics in Bergen, Norway, from May 2017 to January 2020. Information on age, gender, methadone daily doses and serum concentrations, subjective opioid withdrawal symptoms using 16 items Subjective Opioid Withdrawal Scale (SOWS) questionnaire, self-reported adverse effects, and substance use was obtained. Linear mixed modelling was used for analyzing the data. RESULTS The mean age of the participants was 45 years, and 33% were women. Almost half reported mild to moderate subjective opioid withdrawal symptoms, and all had experienced at least one subjective adverse effect. The use of at least one substance was reported by 88% of the participants. Serum concentration-to-dose ratios were lower among those who had reported subjective opioid withdrawal symptoms (p) = 0.039). The total SOWS score (p < 0.001); the specific subjective withdrawal symptoms of anxiety (p = 0.004), bone and muscle aches (p = 0.003), restlessness (p = 0.017), and (slightly) shaking (p = 0.046), also use of heroin (p = 0.015) and alcohol (p = 0.011) were associated with lower methadone concentrations. Cannabis use was slightly related to higher methadone concentrations (p = 0.049). CONCLUSIONS The findings suggest that the patient's self-perceived symptoms and current clinical condition are related to the serum concentrations of methadone. This interpretation supports dose adjustments based on patient-reported symptoms. In some aberrant cases, measurement of serum concentrations together with other individual assessments may be considered to support the clinical decision.

Abstract
Background While patient-reported treatment dissatisfaction is considered an important factor in determining the success of substance use disorder treatment, the levels of dissatisfaction with opioid agonist therapies (OAT) and its relationship with the risk of fentanyl exposure have not been characterized in the context of the ongoing opioid overdose crisis in the US and Canada. Our primary hypothesis was that OAT dissatisfaction was associated with an increased odds of fentanyl exposure. Methods Our objective was to examine self-reported treatment satisfaction among OAT patients in Vancouver, Canada and the association with fentanyl exposure. Longitudinal data were derived from 804 participants on OAT enrolled in two community-recruited harmonized prospective cohort studies of people who use drugs in Vancouver between 2016 and 2018 via semi-annual interviews and urine drug screens (UDS). We employed multivariable generalized estimating equations to examine the relationship between OAT dissatisfaction and fentanyl exposure. Results Out of 804 participants (57.0% male), 222 (27.6%) reported being dissatisfied with OAT at baseline and 1070 out of 1930 observations (55.4%) had fentanyl exposure. The distribution of OAT reported in the sample was methadone (n = 692, 77.7%), buprenorphine-naloxone (n = 82, 9.2%), injectable OAT (i.e., diacetylmorphine or hydromorphone; (n = 65, 7.3%), slow-release oral morphine (n = 44, 4.9%) and other/study medication (n = 8, 1.0%). In the multivariable analysis, OAT dissatisfaction was positively associated with fentanyl exposure (AOR = 1.34; 95% CI: 1.08–1.66). Conclusions A substantial proportion of OAT patients in our sample reported dissatisfaction with their OAT, and more than half were exposed to fentanyl. We also found that those who were dissatisfied with their OAT were more likely to be exposed to fentanyl. These findings demonstrate the importance of optimizing OAT satisfaction in the context of the ongoing opioid overdose crisis.

Abstract
Objectives To describe and explore somatic disease burdens of ageing long-term patients in opioid maintenance treatment (OMT), a unique population emerging in countries offering OMT as a long-term treatment. Methods We used data from the Norwegian Cohort of Patient in Opioid Maintenance Treatment and Other Drug Treatment Study (NorComt). 156 patients enrolled for at least three of the past five years provided data during structured interviews, including on chronic conditions, somatic treatment received, mental distress (SCL-25), and treatment satisfaction. A somatic disease burden was calculated from a list measuring the recent severity of 16 somatic complaints. A hierarchical multiple linear regression analysis identified correlates of somatic disease burden. Results Over half of patients reported at least seven somatic complaints. Reported somatic disease burden was associated with higher mental distress, more chronic conditions, fewer years in OMT, and treatment dissatisfaction. Age was unrelated, and there were few gender differences. These five variables explained 43.6% of the variance in disease burden. Conclusion Long-term OMT patients experience a large range of somatic complaints, and at non-acute levels. As OMT secures longevity for opioid-dependent persons, the clinical focus must be adjusted from acute to chronic care. Providers must address how to optimize health and quality of life while in treatment, as treatment may last for many years.

Abstract
BACKGROUND In the U.S. and Canada, people who inject drugs' (PWID) enrollment in medication-assisted treatment (MAT) has been associated with a reduced likelihood that they will assist others in injection initiation events. We aimed to qualitatively explore PWID's experiences with MAT and other drug treatment and related recovery services in Tijuana Mexico, a resource-limited setting disproportionately impacted by injection drug use. METHODS PReventing Injecting by Modifying Existing Responses (PRIMER) seeks to assess socio-structural factors associated with PWID provision of injection initiation assistance. This analysis drew on qualitative data from Proyecto El Cuete (ECIV), a Tijuana-based PRIMER-linked cohort study. In-depth qualitative interviews were conducted with a subset of study participants to further explore experiences with MAT and other drug treatment services. Qualitative thematic analyses examined experiences with these services, including MAT enrollment, and related experiences with injection initiation assistance provision. RESULTS At PRIMER baseline, 607(81.1%) out of 748 participants reported recent daily IDU, 41(5.5%) reported recent injection initiation assistance, 92(12.3%) reported any recent drug treatment or recovery service access, and 21(2.8%) reported recent MAT enrollment (i.e., methadone). Qualitative analysis (n = 21; female = 8) revealed that, overall, abstinence-based recovery services did not meet participants' recovery goals, with substance use-related social connections in these contexts potentially shaping injection initiation assistance. Themes also highlighted individual-level (i.e., ambivalence and MAT-related stigma) and structural-level (i.e., cost and availability) barriers to MAT enrollment. CONCLUSION Tijuana's abstinence-based drug treatment and recovery services were viewed as unable to meet participants' recovery-related goals, which could be limiting the potential benefits of these services. Drug treatment and recovery services, including MAT, need to be modified to improve accessibility and benefits, like preventing transitions into drug injecting, for PWID.

Abstract
BACKGROUND The opioid epidemic is a public health crisis. Medications for opioid use disorder (MOUD) include: 1) buprenorphine, 2) methadone, and 3) extended-release naltrexone (XR-NTX). Research should investigate patients' and providers' perspectives of MOUD since they can influence prescription, retention, and recovery. METHODS This systematic review focused on patients' and providers' perceptions of MOUD. The review eligibility criteria included inclusion of the outcome of interest, in English, and involving persons ≥18 years. A PubMed database search yielded 1692 results; we included 152 articles in the final review. RESULTS There were 63 articles about buprenorphine, 115 articles about methadone, and 16 about naltrexone. Misinformation and stigma associated with MOUD were common patient themes. Providers reported lack of training and resources as barriers to MOUD. CONCLUSION This review suggests that patients have significant misinformation regarding MOUD. Due to the severity of the opioid epidemic, research must consider the effects of patients' and providers' perspectives on treatment for OUD, including the effects on the type of MOUD prescribed, patient retention and adherence, and ultimately the number of patients treated for OUD, which will aid in curbing the opioid epidemic.

Abstract
BACKGROUND There are few longitudinal follow-up studies of patients in opioid maintenance treatment (OMT). For this reason we performed a follow-up study of a cohort of 67 women who had used OMT-medications during pregnancy an average of ten years earlier. The aim of our study was to explore how the women were doing over time regarding OMT medication adherence and use of other legal and illegal substances, as well as to evaluate the mortality for the women and custody situation for the children in the cohort. METHODS Participants were recruited from two cohorts in our previous pregnancy study covering women who gave birth from 2004 to 2009. Sixty-seven women agreed to be interviewed, which is 73% of the eligible women from our original study. We developed a questionnaire, which we used in the interview, that focused primarily on these women's current life situation (custody of child they had delivered, the use of medications in OMT and other legal and illegal substances, and several other health and social aspects of the participants' lives). RESULTS Two women had died prior to the follow-up. Eighty-one percent of the women had custody of the child they had delivered in our pregnancy study and half the women were single parents. Fifty-four percent of the women were employed. At follow-up, 42% of the women were in methadone maintenance treatment (MMT), 39% were in buprenorphine maintenance treatment (BMT), and 19% had left OMT. One-third of the women had changed their OMT medication during the follow-up period. The majority (77%) were satisfied with their current OMT medication. The women in MMT seemed to be more severe substance dependent than the rest of the participants. There was little use of legal and illegal substances at follow-up, especially among women with custody of their child. The frequency of substance use was low. Fourteen percent of the women were in the process of leaving OMT and another half of the women wanted to leave OMT, but had no plan for how and when. CONCLUSION This follow-up study describes a predominantly well rehabilitated cohort of women who had given birth while in OMT ten years earlier. The majority of the women had custody of their children and used very few legal and illegal drugs. Our findings may be explained partly from a life course perspective, with the women having experienced turning points when starting OMT or becoming mothers.

Abstract
Purpose Opioid maintenance treatment reduces a person’s use of heroin. However, frequent substance use in treatment is a problem. Aim To examine the association between opioid maintenance treatment and opioid/polydrug use, and whether social factors, adverse experiences, social resources, and quality of life are associated with opioid/polydrug use during the first 12 months in treatment. Patients and Methods Forty-seven participants from treatment units in Bergen, Norway participated in five waves of data collection. Every third month, a structured face-to-face interview collected self-reported data on sociodemographic characteristics, opioid/polydrug use, participants’ social resources or adverse experiences, and quality of life. Data were collected as part of KVARUS, the National Quality Register for Substance Abuse Treatment. A multilevel binary logistic regression analysis was conducted to examine the association of opioid/polydrug use and time in current treatment. The analysis included regressions of opioid/polydrug use on time-invariant baseline adverse experiences and social resources, and time-varying reports of quality of life. Results There was a significant negative association between time in treatment and use of opioids, b =−0.89, SE = 0.19, p = <0.01. Furthermore, a negative association of age at substance use on polydrug use was found, b =−0.40, SE =0.19, p = 0.03. A higher overall quality of life was significantly associated with lower odds of opioid use during opioid maintenance treatment, b = −0.62, SE = 0.23, p = < 0.01. Social dimensions, participants’ adverse experiences, and social resources were not associated with polydrug or opioid use. Conclusion Opioid maintenance treatment is associated with lowered opioid use, but to a lesser degree with polydrug use. Our findings add quality of life as an important factor that should be given particular attention because it can offer insight to aspects that can affect the patients’ opioid use.

Abstract
INTRODUCTION In the context of the opioid crisis in North America, the benefits of evidence-based opioid agonist treatments such as buprenorphine/naloxone have not been optimised due to low uptake. Numerous factors contribute to the underuse of buprenorphine, and theory-informed approaches to identify and address implementation barriers and facilitators are needed. This scoping review aims to characterise the barriers and facilitators at the patient, healthcare professional, organisation and system level according to the Theoretical Domains Framework (TDF), and identify gaps to inform practice and policy. METHODS AND ANALYSIS We will conduct a scoping review using established methods and follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews. We will identify English and French-language peer-reviewed literature by searching five electronic bibliographic databases (MEDLINE, Embase, PsychINFO, CINAHL, and SocINDEX), from inception and use Google, websites of key organisations, and two or more custom search engines to identify relevant grey literature. Eligible records will be quantitative or qualitative studies that examine barriers and facilitators to buprenorphine use at the patient, healthcare professional, organisation and system level, and involve participants with diagnosis of opioid use disorder or professionals involved in their care. Two reviewers will be involved in independently screening, reviewing and charting the data and calibration exercises will be conducted at each stage. We will conduct descriptive analysis for the charted data, and deductively code barriers and facilitators using the TDF. ETHICS AND DISSEMINATION As a scoping review of the literature, this study does not require ethics approval. Our dissemination strategy will focus on developing tailored activities to meet the needs of diverse knowledge user audiences. Barriers and facilitators mapped to the TDF can be linked to evidence-based strategies for change to improve buprenorphine use and access, and enable practice to reduce opioid-related harms.

Abstract
This article offers a counter narrative to the current ethnographic
studies on treatment with buprenorphine, in which notions of promised
and experienced normality dominate. In some countries, introduction of
buprenorphine led to a perceived “normalisation” of opioid
substitution treatment, and this new modality was well received.
However, in Norway the response has been almost the opposite: patients
have reacted with feelings of disenfranchisement, failure, and
mistrust. Based on ethnographic fieldwork in Norway, this article
offers comparative insight into local experiences and subjectivities
in the context of the globalisation of buprenorphine. By outlining the
ethnographic description of the pharmaceutical atmosphere of forced
transfers to buprenorphine-naloxone, I show that the social history of
the medication is as significant as its pharmacological qualities for
various treatment effects. An analysis of the reactions to this
treatment modality highlights the reciprocal shaping of lived
experiences and institutional forces surrounding pharmaceutical use in
general and opioids in particular.

Abstract
BACKGROUND AND OBJECTIVES Despite the benefits of maintenance buprenorphine treatment for opioid use disorder (OUD), many individuals report an interest in discontinuing the medication, while also expressing worries about tapering. The purpose of this study was to develop a measure of worries about buprenorphine discontinuation ("Off Bupe") and determine the demographic and clinical characteristics associated with these worries. METHODS Between May 2017 and May 2018, we surveyed adults in an outpatient primary care buprenorphine program (n = 138). Reliability and validity of the Off Bupe measure were examined. RESULTS Participants averaged 39 years of age, 54% were male, average duration of buprenorphine was 189 weeks and 85.5% reported eventually wanting to discontinue buprenorphine, although fewer than 10% were actively tapering. We derived two scales, withdrawal symptom worry (10 items, ɑ = 0.94) and relapse worry (7 items, ɑ = 0.88). Worry about symptoms was positively associated with current buprenorphine dose (P = 0.016), physical discomfort avoidance (P < 0.001), and inversely associated with self-efficacy to quit buprenorphine (P < 0.001) and distress tolerance (P < 0.001). Worry about opioid relapse was associated positively with age (P = 0.019), current buprenorphine dose (P = 0.004), physical discomfort avoidance (P < 0.001), and impulsivity (P = 0.002), and inversely associated with self-efficacy to quit buprenorphine (P < 0.001). DISCUSSION AND CONCLUSIONS Psychometric evaluation of the "Off Bupe" scale demonstrated its content and construct validity and internal reliability. SCIENTIFIC SIGNIFICANCE The scale might help individuals with OUD and their providers identify concerns about discontinuing buprenorphine. (Am J Addict 2019;28:270-276).
