Abstract
STUDY OBJECTIVES Opioid withdrawal is an aversive experience that often exacerbates depressive symptoms and poor sleep. The aims of the present study were to examine the effects of suvorexant on oscillatory sleep-electroencephalography (EEG) band power during medically managed opioid withdrawal, and to examine their association with withdrawal severity and depressive symptoms. METHODS Participants with opioid use disorder (N = 38: age-range:21-63, 87% male, 45% white) underwent an 11-day buprenorphine taper, in which they were randomly assigned to suvorexant (20 mg [n = 14] or 40 mg [n = 12]), or placebo [n = 12], while ambulatory sleep-EEG data was collected. Linear mixed-effect models were used to explore: (1) main and interactive effects of drug group, and time on sleep-EEG band power, and (2) associations between sleep-EEG band power change, depressive symptoms, and withdrawal severity. RESULTS Oscillatory spectral power tended to be greater in the suvorexant groups. Over the course of the study, decreases in delta power were observed in all study groups (β = -189.082, d = -0.522, p = <0.005), increases in beta power (20 mg: β = 2.579, d = 0.413, p = 0.009 | 40 mg β = 5.265, d = 0.847, p < 0.001) alpha power (20 mg: β = 158.304, d = 0.397, p = 0.009 | 40 mg: β = 250.212, d = 0.601, p = 0.001) and sigma power (20 mg: β = 48.97, d = 0.410, p < 0.001 | 40 mg: β = 71.54, d = 0.568, p < 0.001) were observed in the two suvorexant groups. During the four-night taper, decreases in delta power were associated with decreases in depressive symptoms (20 mg: β = 190.90, d = 0.308, p = 0.99 | 40 mg: β = 433.33, d = 0.889 p = <0.001), and withdrawal severity (20 mg: β = 215.55, d = 0.034, p = 0.006 | 40 mg: β = 192.64, d = -0.854, p = <0.001), in both suvorexant groups and increases in sigma power were associated with decreases in withdrawal severity (20 mg: β = -357.84, d = -0.659, p = 0.004 | 40 mg: β = -906.35, d = -1.053, p = <0.001). Post-taper decreases in delta (20 mg: β = 740.58, d = 0.964 p = <0.001 | 40 mg: β = 662.23, d = 0.882, p = <0.001) and sigma power (20 mg only: β = 335.54, d = 0.560, p = 0.023) were associated with reduced depressive symptoms in the placebo group. CONCLUSIONS Results highlight a complex and nuanced relationship between sleep-EEG power and symptoms of depression and withdrawal. Changes in delta power may represent a mechanism influencing depressive symptoms and withdrawal.

Abstract
OBJECTIVE The National Survey on Drug Use and Health (NSDUH), as the primary source of epidemiological substance use data in the US, could illuminate trends in fentanyl use behaviors contributing to the opioid overdose crisis. We hypothesized that the trend in NSDUH prevalence of lifetime fentanyl injection would match the direction and magnitude of the trend in synthetic opioid overdose deaths. METHOD Using logistic regression, we modeled the 2015-2020 trend in synthetic opioid overdose deaths as a proportion of all deaths. We modeled contemporary trends from cross-sectional NSDUH data for (1) lifetime fentanyl injection, (2) past year prescription fentanyl (PF) misuse, (3) prescription tramadol misuse (the other synthetic opioid counted alongside fentanyl in the overdose deaths category), and (4) combined prescription fentanyl or tramadol misuse. Average annual NSDUH weighted sample size was 272,519,038 (51.5% female, 48.5% male). RESULTS Synthetic opioid overdose deaths increased from 2015-2020 (OR 3.39, meaning the odds of a death being from synthetic opioid overdose in 2020 were 3.39 times the odds of death from that cause in 2015, 95% CI: 3.34, 3.44). None of the substance use trends significantly increased. CONCLUSION Per NSDUH data, the prevalence of fentanyl misuse did not significantly increase in tandem with synthetic opioid overdose deaths from 2015 to 2020. Scrutiny of NSDUH's approach to assessing fentanyl misuse casts doubt on the utility of NSDUH fentanyl data collection. We acknowledge recent changes to the survey and recommend two further changes to optimize a vital source of data on behaviors related to the opioid overdose crisis.

Abstract
The opioid crisis is an international public health concern. Treatments for opioid use disorder centre largely on the management of opioid withdrawal, an aversive collection of signs and symptoms that contribute to opioid use disorder. Whereas in the past 50 years more than 90 medications have been developed for depression, only five medications have been developed for opioid use disorder during this period. We posit that underinvestment has occurred in part due to an underdeveloped understanding of opioid withdrawal syndrome. This Personal View summarises substantial gaps in our understanding of opioid withdrawal that are likely to continue to limit major advancements in its treatment. There is no firm consensus in the field as to how withdrawal should be precisely defined; 10-550 symptoms of withdrawal can be measured on 18 scales. The imprecise understanding of withdrawal is likely to result in overestimating or underestimating the severity of an individual's withdrawal syndrome or potential therapeutic effects of different candidate medications. The severity of the opioid crisis is not remitting, and an international research agenda for the study and assessment of opioid withdrawal is necessary to support transformational changes in withdrawal management and treatment of opioid use disorder. Nine actionable targets are delineated here: develop a consensus definition of opioid withdrawal; understand withdrawal symptomatology after exposure to different opioids (particularly fentanyl); understand precipitated opioid withdrawal; understand how co-exposure of other drugs (eg, xylazine and stimulants) influences withdrawal expression; examine individual variation in withdrawal phenotypes; precisely characterise the protracted withdrawal syndrome; identify biomarkers of opioid withdrawal severity; identify predictors of opioid withdrawal severity; and understand which symptoms are most closely associated with treatment attrition or relapse. The US Food and Drug Administration recently established a formal indication for opioid withdrawal that has invigorated interest in drug development for opioid withdrawal management. Action is now needed to support these interests and help industry identify new classes of medications so that real change can be achieved for people with opioid use disorder.

Abstract
Objective There are substantial barriers to conducting research among individuals with stigmatized and complicated health conditions like substance use disorders. These barriers slow progress when developing, refining, and assessing interventions to better treat underserved populations. Virtual focus groups are an innovative method for collecting data from individuals via a discreet and accessible platform which can inform novel as well as existing treatment approaches. This article reports on the feasibility and acceptability of virtual focus groups as a mechanism to recruit and engage geographically and demographically diverse samples of participants with substance use disorders that are otherwise logistically difficult to assess. Method Participants were assessed for eligibility for a virtual focus group study based on demographic features, drug use history, and psychiatric history via a remote, interview-based screening. Focus groups were completed anonymously without video or name-sharing. Discussion contributions, quantified with number of times speaking and total number of words spoken, were compared across gender, and treatment status. Participants provided quantitative and qualitative feedback on the focus group experience in a follow-up survey. Results Focus groups (N=26) based in geographical areas throughout the United States were conducted with 88 individuals with opioid use disorder or stimulant use disorder. Discussion contributions were comparable between genders and among individuals in treatment versus those seeking treatment. A follow-up survey (n=50, 57% of focus group participants) reflected high levels of enjoyment, comfort, and honesty during focus group discussions. Discussion Findings suggest virtual focus groups can be an effective and efficient tool for substance use research.

Abstract
Allelic variations in the A118G SNP of the OPRM1 gene change opioid signaling; however, evaluations of how allelic differences may influence opioid effects are lacking. This human laboratory paradigm examined whether the AA versus AG/GG genotypes determined opioid response profiles. Individuals with limited opioid exposure (N = 100) completed a five-day within-subject, double-blind, placebo-controlled, residential study. Participants were admitted (Day 1), received 4 mg hydromorphone (Day 2) and 0 mg, 2 mg and 8 mg hydromorphone in randomized order (Days 3-5) and completed self-reported visual analog scale (VAS) ratings and Likert scales, observed VAS, and physiological responses at baseline and for 6.5 h post-dose. Outcomes were analysed as peak/nadir effects over time as a function of genotype (available for N = 96 individuals; AG/GG = 13.5%, AA = 86.4%). Participants with AG/GG rated low and moderate doses of hydromorphone as significantly more positive (e.g., Good Effects VAS, coasting, drive, friendly, talkative, stimulation) with fewer negative effects (e.g., itchy skin, nausea, sleepiness), and were also observed as being more talkative and energetic relative to persons with AA. Persons with AG/GG were less physiologically reactive as determined by diastolic blood pressure and heart rate, but had more changes in core temperature compared with those with AA. Persons with AA also demonstrated more prototypic agonist effects across doses; persons with AG/GG showed limited response to 2 mg and 4 mg. Data suggest persons with AG/GG genotype experienced more pleasant and fewer unpleasant responses to hydromorphone relative to persons with AA. Future studies should replicate these laboratory findings in clinical populations to support a precision medicine approach to opioid prescribing.

Abstract
BACKGROUND Opioid use disorders (OUDs) often co-occur with anxiety and depressive disorders. While the proportion of mental health (MH) treatment facilities providing substance use treatment has increased, the proportion of these facilities able to simultaneously treat MH and substance use decreased. This warrants investigation into the integrated treatment needs of persons with a primary OUD diagnosis treated in MH treatment facilities. METHODS Using the Mental Health Client Level Data, we examined a sample of N = 83,975 adults with OUD as their primary diagnosis who received treatment from a MH treatment facility in the United States from 2015 to 2019. Joinpoint regression was used to examine annual trends of the number of individuals with co-occurring anxiety or depression diagnoses. RESULTS Most of the sample were men (53.7%) and received treatment in a community-based program (93.3%). Approximately 17% of the sample had either an anxiety or depressive disorder diagnosis. Approximately 9% of our sample had an anxiety disorder diagnosis, and 10% had a depressive disorder diagnosis. An increase in the number of individuals with a co-occurring anxiety disorder diagnosis from 2015 to 2019 was identified (annual percent change (APC) = 61.4; 95% confidence interval (CI) = [10.0, 136.9]; p =.029). An increase in the number of individuals with a co-occurring depressive disorder diagnosis from 2015 to 2019 was identified (APC = 39.0; 95% CI = [7.4; 79.9]; p =.027). CONCLUSIONS This study highlights increases in adults receiving MH treatment for OUD having co-occurring anxiety or depression diagnoses, furthering the importance of integrated dual disorder treatment.

Abstract
Functional magnetic resonance imaging (fMRI) is increasingly used to non-invasively study the acute impact of psychedelics on the human brain. While fMRI is a promising tool for measuring brain function in response to psychedelics, it also has known methodological challenges. We conducted a systematic review of fMRI studies examining acute responses to experimentally administered psychedelics in order to identify convergent findings and characterize heterogeneity in the literature. We reviewed 91 full-text papers; these studies were notable for substantial heterogeneity in design, task, dosage, drug timing, and statistical approach. Data recycling was common, with 51 unique samples across 91 studies. Fifty-seven studies (54%) did not meet contemporary standards for Type I error correction or control of motion artifact. Psilocybin and LSD were consistently reported to moderate the connectivity architecture of the sensorimotor-association cortical axis. Studies also consistently reported that ketamine administration increased activation in the dorsomedial prefrontal cortex. Moving forward, use of best practices such as pre-registration, standardized image processing and statistical testing, and data sharing will be important in this rapidly developing field.

Data Sources: We searched PubMed, PsycINFO, and EMBASE for randomized trials of psychedelics in humans from 1940 through May 2020 with no language restrictions. PRISMA guidelines were followed. (PROSPERO registration number: PROSPERO-CRD42020205341.). Study Selection: All randomized trials of psychedelics in humans from 1940 through May 2020 were included. Data Extraction: Two independent reviewers performed extraction. Extracted data included study design, demographics, blinding type, whether and how blind integrity was assessed, psychedelic used and dose, drug control condition and dose, type of non-drug control condition, number of dosing sessions, and recruitment source. Outcome data were not collected. Results: In total, 126 articles were included, encompassing 86 unique studies. Of studies with a drug control condition (80), 49 (61.2%) used an inert placebo control, 16 (20.0%) used active comparators, 12 (15.0%) used both, and 3 (3.8%) used only different active psychedelic doses as a control. Only 3 of 21 therapeutic trials compared the use of psychological support to a minimally supportive condition. The majority (81/86; 94%) of studies were blinded, though only 14 (17.3%) included blind assessment; only 8 of these 14 studies assessed participants' blinding. Blinding success, assessed in highly varied ways, was generally poor. Conclusions: Randomized psychedelic trials underutilize elements that would improve quality or provide important information: blind assessment, active drug controls, and testing psychological support against minimal-support conditions. Several queried categories, including blind integrity assessment and details of non-drug control conditions, were insufficiently reported by many reviewed studies. Recommendations are provided to improve trial methods.

Abstract
Background Opioid withdrawal can be expressed as both a spontaneous and precipitated syndrome. Although spontaneous withdrawal is well-characterized, there is no operational definition of precipitated opioid withdrawal. Methods People (N = 106) with opioid use disorder maintained on morphine received 0.4 mg intramuscular naloxone and completed self-report (Subjective Opiate Withdrawal Scale, SOWS), visual analog scale (VAS), Bad Effects and Sick, and observer ratings (Clinical Opiate Withdrawal Scale, COWS). Time to peak severity and minimal clinically important difference (MCID) in withdrawal severity were calculated. Principal component analysis (PCA) during peak severity were conducted and analyzed with repeated measures analyses of variance (ANOVA). Results Within 60 min, 89% of people reported peak SOWS ratings and 90% of people had peak COWS scores as made by raters. Self-reported signs of eyes tearing, yawning, nose running, perspiring, hot flashes, and observed changes in pupil diameter and rhinorrhea/lacrimation were uniquely associated with precipitated withdrawal. VAS ratings of Bad Effect and Sick served as statistically significant severity categories (0, 1-40, 41-80, and 81-100) for MCID evaluations and revealed participants' identification with an increase of 10 [SOWS; 15% maximum percent effect (MPE)] and 6 (COWS; 12% MPE) points as meaningful shifts in withdrawal severity indicative of precipitated withdrawal. Conclusion Data suggested that a change of 10 (15% MPE) and 6 (12% MPE) points on the SOWS and COWS, respectively, that occurred within 60 min of antagonist administration was identified by participants as a clinically meaningful increase in symptom severity. These data provide a method to begin examining precipitated opioid withdrawal.

Abstract
Importance Novel treatments for opioid use disorder (OUD) are needed to address both the ongoing opioid epidemic and long-standing barriers to existing OUD treatments that target the endogenous μ-opioid receptor (MOR) system. The goal of this review is to highlight unique clinical trial design considerations for the study of emerging treatments for OUD that address targets beyond the MOR system. In November 2019, the Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks (ACTTION) public-private partnership with the US Food and Drug Administration sponsored a meeting to discuss the current evidence regarding potential treatments for OUD, including cannabinoids, psychedelics, sedative-hypnotics, and immunotherapeutics, such as vaccines. Observations Consensus recommendations are presented regarding the most critical elements of trial design for the evaluation of novel OUD treatments, such as: (1) stage of treatment that will be targeted (eg, seeking treatment, early abstinence/detoxification, long-term recovery); (2) role of treatment (adjunctive with or independent of existing OUD treatments); (3) primary outcomes informed by patient preferences that assess opioid use (including changes in patterns of use), treatment retention, and/or global functioning and quality of life; and (4) adverse events, including the potential for opioid-related relapse or overdose, especially if the patient is not simultaneously taking maintenance MOR agonist or antagonist medications. Conclusions and Relevance Applying the recommendations provided here as well as considering input from people with lived experience in the design phase will accelerate the development, translation, and uptake of effective and safe therapeutics for individuals struggling with OUD.

Abstract
Sleep impairment is a common comorbid and debilitating symptom for persons with opioid use disorder (OUD). Research into underlying mechanisms and efficacious treatment interventions for OUD-related sleep problems requires both precise and physiologic measurements of sleep-related outcomes and impairment. This pilot examined the feasibility of a wireless sleep electroencephalography (EEG) monitor (Sleep Profiler™) to measure sleep outcomes and architecture among participants undergoing supervised opioid withdrawal. Sleep outcomes were compared to a self-reported sleep diary and opioid withdrawal ratings. Participants (n = 8, 100% male) wore the wireless EEG 85.6% of scheduled nights. Wireless EEG detected measures of sleep architecture including changes in total, NREM and REM sleep time during study phases, whereas the diary detected changes in wakefulness only. Direct comparisons of five overlapping outcomes revealed lower sleep efficiency and sleep onset latency and higher awakenings and time spent awake from the wireless EEG versus sleep diary. Associations were evident between wireless EEG and increased withdrawal severity, lower sleep efficiency, less time in REM and non-REM stages 1 and 2, and more hydroxyzine treatment; sleep diary was associated with total sleep time and withdrawal only. Data provide initial evidence that a wireless EEG is a feasible and useful tool for objective monitoring of sleep in persons experiencing acute opioid withdrawal. Data are limited by the small and exclusively male sample, but provide a foundation for using wireless EEG sleep monitors for objective evaluation of sleep-related impairment in persons with OUD in support of mechanistic and treatment intervention research.

Abstract
BACKGROUND Sleep disturbances and disorders are a common and sometimes recalcitrant problem in persons recovering from substance use disorders (SUDs). As such, several randomized-controlled trials (RCTs) have been conducted to address sleep disturbances in a variety of SUD subpopulations and clinical scenarios. The goal of this systematic review was to collate patient-reported sleep outcomes used in past SUD-related RCTs to provide guidance for future sleep research in persons with SUDs. METHODS This systematic review was registered in the International Prospective Register of Systematic Reviews (PROSPERO) on May 7th, 2020 (CRD42020182004). Studies were included if they were peer-reviewed manuscripts describing RCTs in an SUD population. RESULTS The initial search yielded 13,403 candidate articles, and 76 met a priori criteria and were included in this review. Thirty-five (46.1%) assessed sleep as a primary outcome (i.e., sleep improvement was the primary goal of the research) and 41 (53.9%) assessed sleep as a secondary outcome (i.e., sleep improvement was an important outcome, but not the primary outcome). The most commonly used measures included the Pittsburgh Sleep Quality Index, the Insomnia Severity Index, and sleep diaries. However, multiple additional sleep assessments were also used, including visual analogue and Likert scales. CONCLUSIONS The field of addiction medicine would benefit from a streamlined approach in assessing patient-reported sleep in RCTs, including commonly used and validated assessments of sleep quality, inserting daily or repeated measures into RCTs, and including questionnaires that assess clinically relevant insomnia or other sleep disorders.

Abstract
BACKGROUND AND AIMS Prospective trial registration can increase research integrity. This Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks (ACTTION) review was designed to compare the primary outcomes (PO) reported in registries with associated publications for opioid use disorder (OUD) clinical trials. DESIGN The World Health Organization's International Clinical Trials Registry Platform (ICTRP) was searched for completed trials (2010 through 2019). Associated publications were identified and paired with trial registry data based on the publication date. MEASUREMENTS Reviewers independently rated the occurrence of discrepancies between the POs in the registry compared to the publication. An analysis of prospective versus retrospective registration was also completed. FINDINGS One-hundred and forty trials were identified in the search, and 43 registry-publication pairs evaluated. Only 34 of the 43 pairs could be examined for discrepancies because nine did not report a PO in registry and publication. Of the 34 pairs, only four met rigorous criteria for prospective trial registration and had an exact match of POs. In contrast, the majority of the 34 trials, or 80%, had inconsistent POs (e.g., registered secondary outcomes published as primary; the timing of PO not specified) and/or were retrospectively registered. CONCLUSIONS Many clinical trials focused on OUD have not met the standards of trial registration, such as consistent reporting of POs and prospective registration. Failure to properly register trial characteristics undermines the validity of research findings and can delay the development of life-saving treatments. Recommendations for improving prospective trial reporting practices are provided.

Abstract
BACKGROUND Despite efforts towards gender parity and some improvement over time, gender bias in peer review remains a pervasive issue. We examined gender representation and homophily in the peer review process for Drug and Alcohol Dependence (DAD). METHODS We extracted data for papers submitted to DAD between 2004 and 2019, inclusive. Inferred gender was assigned to handling editors and reviewers using the NamSor gender inference Application Programming Interface (API). RESULTS Men and women handling editors were approximately equally likely to invite women reviewers over time, with only a few exceptions. Over time, 47.1% of editors were women, and 42.6% of review invitations were sent to women. Men were largely consistent over time in their likelihood of accepting a review invitation, while the likelihood of women accepting a review invitation was more variable over time. Gender differences in rates of accepting a review invitation were minimal; however, as women approached half of all invited reviewers in recent years, there has been a greater trend for women, relative to men, to decline review invitations. Evidence of homophily on the part of reviewers accepting invitations was minimal, but in certain years, a tendency to accept review invitations at higher rates from editors of the same gender was observed. DISCUSSION Given the benefits of diversity in scientific advancement, these results underline the importance of continuing efforts to increase gender diversity among editors and in reviewer pools, and the need for reviewers to be mindful of their own reviewing practices.

Abstract
Increased orexin/hypocretin signaling is implicated in opioid withdrawal, sleep disturbances, and drug-seeking behaviors. This study examined whether a dual-orexin receptor antagonist would improve sleep and withdrawal outcomes when compared with placebo during a buprenorphine/naloxone taper. Thirty-eight participants with opioid use disorder were recruited to a clinical research unit and maintained on 8/2 to 16/4 mg of buprenorphine/naloxone treatment for 3 days before being randomized to 20 mg of suvorexant (n = 14), 40 mg of suvorexant (n = 12), or placebo (n = 12); 26 individuals completed the study. After randomization, participants underwent a 4-day buprenorphine/naloxone taper and 4-day post-taper observation period. Total sleep time (TST) was collected nightly with a wireless electroencephalography device and wrist-worn actigraphy; opioid withdrawal symptoms were assessed via the Subjective Opiate Withdrawal Scale (SOWS); and abuse potential was assessed on a 0- to 100-point visual analog scale of "High" every morning. A priori outcomes included two-group (collapsing suvorexant doses versus placebo) and three-group comparisons of area-under-the-curve (AUC) scores for TST, SOWS, and High. In two-group comparisons, participants receiving suvorexant displayed increased TST during the buprenorphine/naloxone taper and decreased SOWS during the post-taper period. In three-group comparisons, participants receiving 20 mg of suvorexant versus placebo displayed increased AUC for TST during the buprenorphine/naloxone taper, but there was no difference in SOWS among groups. There was no evidence of abuse potential in two- or three-group analyses. The results suggest that suvorexant might be a promising treatment for sleep and opioid withdrawal in individuals undergoing a buprenorphine/naloxone taper.

Abstract
Psychedelic substances have played important roles in diverse cultures, and ingesting various plant preparations to evoke altered states of consciousness has been described throughout recorded history. Accounts of the subjective effects of psychedelics typically focus on spiritual and mystical-type experiences, including feelings of unity, sacredness, and transcendence. Over the past two decades, there has been increasing interest in psychedelics as treatments for various medical disorders, including chronic pain. Although concerns about adverse medical and psychological effects contributed to their controlled status, contemporary knowledge of psychedelics suggests that risks are relatively rare when patients are carefully screened, prepared, and supervised. Clinical trial results have provided support for the effectiveness of psychedelics in different psychiatric conditions. However, there are only a small number of generally uncontrolled studies of psychedelics in patients with chronic pain (e.g., cancer pain, phantom limb pain, migraine, and cluster headache). Challenges in evaluating psychedelics as treatments for chronic pain include identifying neurobiologic and psychosocial mechanisms of action and determining which pain conditions to investigate. Truly informative proof-of-concept and confirmatory randomized clinical trials will require careful selection of control groups, efforts to minimize bias from unblinding, and attention to the roles of patient mental set and treatment setting. Perspective: There is considerable promise for the use of psychedelic therapy for pain, but evidence-based recommendations for the design of future studies are needed to ensure that the results of this research are truly informative.

Abstract
HIV and psychoactive substances can impact the integrity of the basal ganglia (BG), a neural substrate of cognition, motor control, and reward-seeking behaviors. This study assessed BG gray matter (GM) volume as a function of polysubstance (stimulant and opioid) use and HIV status. We hypothesized that comorbid polysubstance use and HIV seropositivity would alter BG GM volume differently than would polysubstance use or HIV status alone. We collected structural MRI scans, substance use history, and HIV diagnoses. Participants who had HIV (HIV +), a history of polysubstance dependence (POLY +), both, or neither completed assessments for cognition, motor function, and risk-taking behaviors (N = 93). All three clinical groups showed a left-lateralized pattern of GM reduction in the BG relative to controls. However, in the HIV + /POLY + group, stimulant use was associated with increased GM volume within the globus pallidus and putamen. This surpassed the effects from opioid use, as indicated by decreased GM volume throughout the BG in the HIV-/POLY + group. Motor learning was impaired in all three clinical groups, and in the HIV + /POLY + group, motor learning was associated with increased caudate and putamen GM volume. We also observed associations between BG GM volume and risk-taking behaviors in the HIV + /POLY- and HIV-/POLY + groups. The effects of substance use on the BG differed as a function of substance type used, HIV seropositivity, and BG subregion. Although BG volume decreased in association with HIV and opioid use, stimulants can, inversely, lead to BG volume increases within the context of HIV.

Abstract
ABSTRACT Randomized clinical trials have demonstrated the efficacy of opioid analgesics for the treatment of acute and chronic pain conditions, and for some patients, these medications may be the only effective treatment available. Unfortunately, opioid analgesics are also associated with major risks (eg, opioid use disorder) and adverse outcomes (eg, respiratory depression and falls). The risks and adverse outcomes associated with opioid analgesics have prompted efforts to reduce their use in the treatment of both acute and chronic pain. This article presents Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT) consensus recommendations for the design of opioid-sparing clinical trials. The recommendations presented in this article are based on the following definition of an opioid-sparing intervention: any intervention that (1) prevents the initiation of treatment with opioid analgesics, (2) decreases the duration of such treatment, (3) reduces the total dosages of opioids that are prescribed for or used by patients, or (4) reduces opioid-related adverse outcomes (without increasing opioid dosages), all without causing an unacceptable increase in pain. These recommendations are based on the results of a background review, presentations and discussions at an IMMPACT consensus meeting, and iterative drafts of this article modified to accommodate input from the co-authors. We discuss opioid sparing definitions, study objectives, outcome measures, the assessment of opioid-related adverse events, incorporation of adequate pain control in trial design, interpretation of research findings, and future research priorities to inform opioid-sparing trial methods. The considerations and recommendations presented in this article are meant to help guide the design, conduct, analysis, and interpretation of future trials.

Abstract
OBJECTIVES Acute pain management in patients with opioid use disorder who are maintained on methadone presents unique challenges due to high levels of opioid tolerance in this population. This randomized controlled study assessed the analgesic and abuse liability effects of escalating doses of acute intravenous (IV) hydromorphone versus placebo utilizing a validated experimental pain paradigm, quantitative sensory testing (QST). METHODS Individuals (N = 8) without chronic pain were maintained on 80-100 mg/day of oral methadone. Participants received four IV, escalating/incremental doses of hydromorphone over 270 min (32 mg total) or four placebo doses within a session test day. Test sessions were scheduled at least one week apart. QST and abuse liability measures were administered at baseline and after each injection. RESULTS No significant differences between the hydromorphone and placebo control conditions on analgesic indices for any QST outcomes were detected. Similarly, no differences on safety or abuse liability indices were detected despite the high doses of hydromorphone utilized. Few adverse events were detected, and those reported were mild in severity. CONCLUSIONS The findings demonstrate that methadone-maintained individuals are highly insensitive to the analgesic effects of high-dose IV hydromorphone and may require very high doses of opioids, more efficacious opioids, or combined non-opioid analgesic strategies to achieve adequate analgesia.

Abstract
OBJECTIVES Efforts to improve buprenorphine access for opioid use disorder have focused on increasing the number of waivered providers. However, it is unknown how efforts to increase initial prescribing result in a sustained pool of prescribers. We examine the prevalence of year-to-year provider-level buprenorphine prescribing, and provider- and state-level factors associated with provider continuity. METHODS Providers prescribing buprenorphine/naloxone within the Medicare Part D claims database were evaluated from 2013 to 2017 with prescriber continuity measured as prescriptions made in consecutive years from the same provider (N = 14,222 unique providers; 6670 in 2013). RESULTS The number of providers prescribing buprenorphine/naloxone within Medicare Part D increased from 2013 to 2017. The majority of providers prescribed buprenorphine/naloxone to 10 or fewer beneficiaries. Approximately 84% of providers prescribing buprenorphine/naloxone in 1 year prescribed it in the following year. Continuous prescribing from 2013 to 2017 was 59.4%, which was 86% the rate of a comparator chronic health medication (ie, lisinopril). Survival analyses indicated that female providers (adjusted hazard ratios [AHR] = 1.30, P < 0.001) and clinical neuroscience specialties such as psychiatry (AHR = 1.21, P < 0.001) exhibited greater discontinuation rates, whereas those with higher buprenorphine/naloxone beneficiary loads (AHR = 0.50, P < 0.001) and in states with a greater increase in overdose mortality rates (AHR = 0.88, P < 0.05) showed lower discontinuation rates. CONCLUSIONS These data support evidence that providers who begin prescribing buprenorphine continue prescribing, although short of maximum capacity. Efforts to help providers become waivered, understand the impact of overdose fatalities in their area, and prescribe to multiple patients are likely to generate an enduring positive contribution to the number of treated patients.

Abstract
OBJECTIVES There has been advocacy for legalization of abusable substances, but systematic data on societal beliefs regarding such legalization are limited. People who use substances may have unique beliefs about legalization, and this study assessed whether they would be in favor of drug legalization/decriminalization. It was hypothesized that those who use particular drugs (especially marijuana) would support its legalization/decriminalization, but that this would not be the case across all classes (especially opioids and stimulants). METHODS A nationwide sample of 506 adults were surveyed online to assess demographic characteristics, substance misuse, and beliefs regarding drug legalization/decriminalization. Legalization/decriminalization beliefs for specific drugs were assessed on an 11-point scale (0, strongly disagree; 10, strongly agree). RESULTS For persons with opioid misuse (15.4%), when asked about their agreement with: "heroin should be legalized," the mean score was 4.6 (SEE = 0.4; neutral). For persons with stimulant misuse (12.1%), when asked about their agreement with: "cocaine should be legalized," the score was 4.2 (0.5). However, for persons with marijuana misuse (34.0%), when asked about their agreement with: "medical marijuana should be legalized" the score was 8.2 (0.3; indicating agreement), and for "recreational marijuana" the score was also 8.2 (0.3). CONCLUSIONS These results suggest that persons who used marijuana strongly support the legalization of both recreational and medical marijuana, whereas persons who primarily have opioid or stimulant misuse have less strongly held beliefs about legalization of substances within those respective categories. By including those who misuse drugs, these data assist in framing discussions of drug legalization and have the potential to inform drug policy considerations.

Abstract
BACKGROUND Despite effective, evidence-based medications for opioid use disorder (MOUD), these treatments remain underutilized. This may be due to multiple reasons. Family members may impact patient decision-making when choosing an opioid use disorder (OUD) treatment. While there has been work on patient preferences and attitudes towards opioid use disorder (OUD) treatment, to date, there has been minimal work assessing the attitudes of family member towards OUD treatment and recovery. METHODS Participants were ≥ 18 years of age and endorsed having a first-degree family member with past-year treatment for OUD. Participants were recruited via online crowdsourcing and were asked a number of questions regarding their desired outcomes for OUD treatment, and their familiarity, approval, and perceived effectiveness of various OUD treatment options. RESULTS The most commonly reported desired treatment outcome (50 %) was for family members to never use any kind of opioid, including maintenance therapies or opioid analgesics. Mean familiarity ratings for MOUD (rated 0-100) were relatively low, with naltrexone being the least familiar (32.3). Among those who endorsed a familiarity rating of at least 30 for a given treatment, mean approval and effectiveness ratings were relatively low-buprenorphine (approve 55.1; effective 54.1), methadone (approve 51.9; effective 49.3), naltrexone (approve 61.6; effective 55.9). These were lower than approval and effectiveness ratings for all non-MOUD treatments queried. CONCLUSIONS These findings highlight a need for clinicians and researchers to engage with family members' regarding their preferences and understanding of treatment, and to better understand how this might impact patient engagement with treatment.

Abstract
OBJECTIVE This study examined Electronic Health Record (EHR) utilization among US substance use disorder (SUD) versus mental health (MH) treatment facilities. METHODS Data from the National Survey of Substance Abuse Treatment Services and the National Mental Health Services Survey were used to examine differences in clinical and administrative utilization of EHR. RESULTS EHR use was significantly less common among SUD facilities compared to MH facilities for both non-exclusive (mixed computer and paper) and exclusive (paper-free) use. Fewer than 25 % of facilities of either type reported exclusive EHR use for core clinical activities (progress notes, laboratory monitoring, and prescriptions) with wide variability among states. Being an inpatient facility, having Joint Commission accreditation, being a private-for-profit, or a public facility were significantly positively associated with exclusive EHR use for core clinical activities; these associations were stronger among SUD facilities than MH facilities. Accepting Medicare was associated with exclusive EHR use for core clinical activities in both facility types, while accepting private insurance was associated with such use only among SUD treatment facilities. CONCLUSIONS EHR adoption among SUD facilities lags behind MH facilities. However, exclusive EHR use for clinical purposes remains elusive for both types of facilities with no more than a quarter of facilities in any state reporting such use. Some of the factors associated with exclusive EHR use for clinical purposes among SUD treatment facilities-such as Joint Commission accreditation-may be policy leverage points to expedite EHR adoption in these facilities.

Abstract
The study examined associations between medication assisted treatment (MAT) and psychiatric symptom severity, measured by Positive and Negative Symptom Scale (PANSS), among individuals with serious mental illness and a history of heroin use. Of 271 participants, 32% (n=87) reported a history of heroin use and, of those, 14.9% (n=13) reported MAT. Higher scores in PANSS Total, Negative, and Disordered subscales were associated with lower odds, while being on an antipsychotic with higher odds, of receiving MAT. This supports the greater need for clinician attention to different symptom clusters and targeted multidimensional interventions as a way to increase MAT participation.

Abstract
BACKGROUND A variety of substance use-related topics are discussed in the public discourse; however, it is unknown how public discussion of published substance-related findings relates to manuscript downloads and citations. This manuscript examines how traditional and social media coverage of published findings about substance use affects downloads and scientific citations. METHODS Altmetric and bibliographic information was obtained for manuscripts published in Drug and Alcohol Dependence between 2018 and 2019 (n = 943). Associations were examined between news and social media coverage (i.e., Twitter, Facebook) in relation to number of manuscript downloads and number of citations. This was done in a bivariable manner and in a multivariable manner examining correlates of being in the top 10th percentile of downloads and citations. RESULTS 73.3 % of articles were shared on Twitter, 23.6 % were shared on Facebook, and 13.9 % were covered in news sources (with 4.0 % receiving major media coverage). Epidemiology papers were among the most covered in the news, and e-cigarette review papers were among the most downloaded. News and social media coverage were positively associated with number of downloads and citations in bivariable models and with achieving the top 10 % of downloads and citations in multivariable models (ps < .001). Publishing a press release was associated with higher likelihood of receiving additional news coverage (aPR = 7.85, 95 % CI: 5.15-11.97). CONCLUSIONS Traditional and social media coverage of manuscripts focusing on substance use are associated with more downloads and citations. Researchers should consider sharing findings not only to increase downloads and citations but also to educate the general public.

Abstract
Preclinical studies demonstrate that sleep disruption diminishes morphine analgesia and modulates reward processing. We sought to translate these preclinical findings to humans by examining whether sleep disruption alters morphine's analgesic and hedonic properties. We randomized 100 healthy adults to receive morphine versus placebo after two nights of undisturbed sleep (US) and two nights of forced awakening (FA) sleep disruption. Sleep conditions were counterbalanced, separated by a two-week washout. The morning after both sleep conditions, we tested cold pressor pain tolerance before and 40-min after double-blind injection of .08 mg/kg morphine or placebo. The primary outcome was the analgesia index, calculated as the change in cold pressor hand withdrawal latency (HWL) before and after drug injection. Secondary outcomes were ratings of feeling "high," drug "liking," and negative drug effects. We found a significant sleep condition by drug interaction on the analgesia index (95% CI - 0.57, - 0.001). After US, subjects receiving morphine demonstrated significantly longer HWL compared to placebo (95% CI 0.23, 0.65), but not after FA (95% CI - 0.05, 0.38). Morphine analgesia was diminished threefold under FA, relative to US. After FA, females (95% CI - 0.88, - 0.05), but not males (95% CI - 0.23, 0.72), reported decreased subjective "high" effects compared to US. After FA, females (95% CI 0.05, 0.27), but not males (95% CI - 0.10, 0.11), administered morphine reported increased negative drug effects compared to US. These data demonstrate that sleep disruption attenuates morphine analgesia in humans and suggest that sleep disturbed males may be at greatest risk for problematic opioid use.

Abstract
Although opioid withdrawal ratings are frequently used as primary outcomes for therapeutic trials, there has been limited empirical examination of opioid withdrawal symptom onset or etiology as an outcome, and also little examination of differences in outcomes between patient-reported and observer-ratings of withdrawal. Patient-reported (Subjective Opiate Withdrawal Scale, SOWS) and observer ratings (Clinical Opiate Withdrawal Scale, COWS) of opioid withdrawal collected as part of a randomized controlled residential clonidine, tramadol-extended release, and buprenorphine/naloxone 7-day taper for opioid withdrawal management were analyzed. Withdrawal ratings were collected seven times daily and primary outcomes were percent of participants (N = 103) endorsing symptoms, time of symptom onset, and relationship of scales to taper completion. Participants had variable endorsement of specific symptoms, ranging from 37 % ("feel like vomiting") to 97 % ("change in resting pulse"). Symptoms were more likely to be reported on the SOWS than COWS. Most symptoms began around 8 h after last dose, though comparison of like symptoms across the scales revealed patients reported symptoms on the SOWS > 10 h before they were observed on the COWS. SOWS peak severity score was more closely associated with taper completion than the COWS. Data suggest the patient-reported SOWS demonstrated a higher level of symptom endorsement, earlier detection of symptom onset, and better association with taper completion relative to the observer rated COWS. These data provide insight into the etiology of opioid withdrawal symptom expression and time course that can be used to inform treatment intervention timing and provide a baseline for other withdrawal evaluations.

Abstract
Technology-assisted treatment (TAT) holds promise for innovative assessment, prevention, and treatment of substance use disorders (SUD). The widespread access to TAT makes it a potentially cost-effective and inventive option available for delivery in multiple settings. This study assessed acceptability of the web-based Therapeutic Education System (TES) in hospitalized dual diagnosis patients with SUDs and other psychiatric disorders. Methods: Eligible participants were nonpsychotic, voluntary patients with self-reported drug or alcohol use in the 30 days prior to admission. They were randomly assigned to treatment as usual (TAU, n = 47) or TAU + TES (n = 48). Acceptability of this Internet-based intervention was assessed by observed utilization and self-report. Results: The TAU + TES group (# analyzed = 41) completed a mean total of 5.5 (SEM = 0.8) modules with about one module per day while hospitalized and rated TES highly on several constructs of acceptability, including novelty, usefulness and ease of understanding. Conclusions: These findings support further exploration of TAT for treatment expansion in a high acuity, dual diagnosis population and indicate the value of future research on efficacy.

Abstract
INTRODUCTION The illicit opioid supply in the U.S. is increasingly adulterated with fentanyl. As such, persons with opioid use disorder (OUD) may be regularly exposed to fentanyl, however, the pharmacokinetics of repeated fentanyl exposure are not well understood. The current study aimed to quantify renal clearance of fentanyl in OUD patients presenting to residential treatment. METHODS Participants (N = 12) who presented to a 28-day residential treatment program were enrolled if they tested positive for fentanyl at intake. Urine samples were collected every 2-3 days and were quantitatively tested for fentanyl, norfentanyl, and creatinine via liquid chromatography mass spectrometry (LC-MS). Fentanyl clearance was defined as the time since last illicit opioid use and the median time between last positive and first negative fentanyl urine screen. RESULTS Participants had a mean and standard deviation (SD) age of 28.9 (11.0), were 67 % male, and 83 % white. The mean (SD) time for fentanyl and norfentanyl clearance was 7.3 (4.9) and 13.3 (6.9) days, respectively. One participant continued to test positive for fentanyl for 19 days and norfentanyl for 26 days following their last use, and left treatment without testing negative for norfentanyl. CONCLUSION Fentanyl clearance in persons with OUD is considerably longer than the typical 2-4 day clearance of other short-acting opioids. The findings of this study might explain recent reports of difficulty in buprenorphine inductions for persons who use fentanyl, and point to a need to better understand the pharmacokinetics of fentanyl in the context of opioid withdrawal in persons who regularly use fentanyl.

Abstract
There is considerable variability in the use of outcome measures in clinical trials for cannabis use disorder (CUD), and a lack of consensus regarding optimal outcomes may have hindered development and approval of new pharmacotherapies. The goal of this paper is to summarize an evaluation of assessment measures and clinical endpoints for CUD clinical trials, and propose a research agenda and priorities to improve CUD clinical outcome assessments. The primary recommendation is that sustained abstinence from cannabis should not be considered the primary outcome for all CUD clinical trials as it has multiple limitations. However, there are multiple challenges to the development of a reliable and valid indicator of cannabis reduction, including the lack of a standard unit of measure for the various forms of cannabis and products and the limitations of currently available biological and self-report assessments. Development of a core toolkit of assessments is needed to both allow flexibility for study design, while facilitating interpretation of outcomes across trials. Four primary agenda items for future research are identified to expedite development of improved clinical outcome assessments for this toolkit: (1) determine whether minimally invasive biologic assays could identify an acute level of cannabis use associated with psychomotor impairment or other cannabis-related harms; (2) create an indicator of quantity of cannabis use that is consistent across product types; (3) examine the presence of cannabis-specific functional outcomes; and (4) identify an optimal duration to assess changes in CUD diagnostic criteria.

Abstract
BACKGROUND AND OBJECTIVES Individuals exposed to fentanyl are at risk of precipitated withdrawal using typical buprenorphine/naloxone induction procedures. METHODS This case series describes buprenorphine/naloxone inductions of four individuals who tested positive for fentanyl. RESULTS Buprenorphine-precipitated withdrawal was observed in two individuals who completed a conventional buprenorphine/naloxone induction strategy. Two more individuals completed a revised buprenorphine/naloxone induction strategy that did not precipitate withdrawal. DISCUSSION AND CONCLUSION Using multiple 2 mg doses of buprenorphine/naloxone in patients already in mild/moderate withdrawal improved outcomes. SCIENTIFIC SIGNIFICANCE Persons who use illicit fentanyl might be less likely to experience precipitated withdrawal from this revised buprenorphine/naloxone induction strategy.

Abstract
OBJECTIVE Little is known about the correlates of and recent trends in implementation of Integrated Dual Diagnosis model, an evidence-based approach for dual diagnosis services, in US mental health facilities between 2010 and 2018. METHODS Changes over time in Integrated Dual Diagnosis Treatment use were examined using multiple waves of a national survey of mental health treatment facilities that reported offering any substance use services. State and facility correlates of offering integrated dual diagnosis services among these facilities in 2018 were examined. RESULTS The proportion of mental health treatment facilities that reported offering any substance use services increased significantly from 50.1% in 2010 to 57.1% in 2018. Among these facilities, significantly fewer reported offering Integrated Dual Diagnosis Treatment in 2018 (74.8%) than in 2010 (79.6%). The prevalence of Integrated Dual Diagnosis Treatment use increased in more recent years in tandem with increase in substance use services, though the increases in Integrated Dual Diagnosis Treatment have not matched the expansion of substance use services. Mental health facilities with substance use services more commonly offered other mental health services and had more funding sources available. Facilities with any substance use disorder services that offered Integrated Dual Diagnosis Treatment were more commonly licensed by State Substance Agencies and more commonly offered psychotropics and group therapies. Facilities located in states that implemented the Integrated Dual Diagnosis Treatment model had a higher odds of offering this model. CONCLUSIONS The growth in the co-location of substance use treatment services within mental health treatment facilities has not been matched by true integration of these treatments, highlighting the need for further efforts to comprehensively address the complex needs of dually diagnosed patients.

Abstract
BACKGROUND Cannabis use and major depressive disorder (MDD) are common and often co-morbid in adolescents, but the nature and directionality of the relationship between these two conditions remains obscure. METHODS We examined results from the National Survey on Drug Use and Health. Weighted demographics were compared between adolescents with a history of cannabis use (N = 14,873) and never users (N = 73,079). Weighted logistic regression controlling for demographic variables and other substance use was used to determine the relationship between cannabis use frequency and MDD. RESULTS Adolescents with any history of cannabis use had significantly higher rates of lifetime and past year MDD, MDD with severe role impairment, and past year suicide attempt (p < 0.001). Comparing use frequency groups in the adjusted model revealed that heavy users (weekly or greater use) had significantly lower predicted prevalence of lifetime and past year MDD, and past year MDD with severe role impairment compared to light users and those who used cannabis >1 year ago. Rates of reported past year suicide attempt did not differ significantly by cannabis use frequency. CONCLUSIONS Adolescents with any cannabis use history have significantly higher rates of MDD. However, the directionality between frequency of use and MDD is counter to what was expected.

Abstract
Opioid use disorder (OUD) is a public health crisis. Differences in opioid withdrawal severity that predict treatment outcome could facilitate the process of matching patients to treatments. This is a secondary analysis of a randomized controlled trial (RCT) that enrolled treatment seeking heroin-users (N = 89, males = 78) into a residential study. Participants maintained on morphine (30 mg, subcutaneous, four-times daily) underwent a naloxone (0.4 mg, IM = intramuscular) challenge session to precipitate withdrawal. Area-under-the-curve (AUC) values from self-reported withdrawal ratings during the challenge session were analyzed using K-means clustering, revealing two phenotype groups. Withdrawal and retention from the subsequent 14-day double-blind, double-dummy RCT comparing three study medications (clonidine, tramadol-ER, and buprenorphine) were evaluated as a function of phenotype. Cluster analyses suggested HIGH (N = 37; mean [SD] subjective opiate withdrawal scale [SOWS]-AUC 123.7 [65.8]) and LOW (N = 52; SOWS-AUC 68.0 [47.7]) withdrawal phenotype groups. HIGH participants were significantly more female and had lower body mass indices than LOW participants; no drug-use variables were significant. Regarding RCT outcomes, HIGH phenotype participants were less likely to be retained in the study (P = 0.02) and had higher mean self-reported withdrawal (P = 0.05) than LOW phenotype participants. A significant interaction in RCT retention was observed between phenotype (P = 0.02) and study medication (P < 0.01). Self-reported withdrawal was significant for phenotype (P = 0.02); study medication trended towards significance (P = 0.07). Results suggest patients have meaningfully different experiences of opioid withdrawal that may predict differential response to opioid pharmacotherapies during supervised withdrawal. Additional prospective research to replicate and more thoroughly evaluate withdrawal phenotype correlates and sex differences is warranted.

Abstract
BACKGROUND Alcohol use disorder (AUD) is a growing problem among older adults. The aim of this study was to quantify trends in first-time treatment admissions for older adults with AUD in the U.S., and examine the medical and specialty clinical services offered by treatment facility type. METHODS Patient level data were collected from the Treatment Episode Data Set for Admissions between 2004-2017. Joinpoint regression was used to identify unique trends in first-time treatment admissions for older adults with AUD. Provider level data were collected from the National Survey of Substance Abuse Treatment Services (N-SSATS) for the most recent year, 2017. N-SSATS data were grouped by facility type (inpatient/hospital, residential, and outpatient treatment) to examine differences in medications and clinical services. RESULTS Among all persons seeking first-time treatment for AUD with alcohol as their primary drug of choice (n = 3,606,948), there was a significant increase in the proportion of older adults seeking treatment from 2004 to 2017 (p-trend<0.001), with an average annual percent change of 6.8% (95% confidence intervals: 6.2%-7.4%). The majority of older adults with AUD sought treatment in outpatient and residential facilities, which compared to hospital-based facilities had lower odds of offering supervised detoxification, acamprosate, naltrexone, psychiatric medications, or mental health services (all p-values<0.001). Fewer than 25% of hospital-based and 20% of residential or outpatient facilities offered specialty services for older adults. CONCLUSIONS U.S. substance abuse treatment providers are not compensating for the changing nature of admissions by older adults, and are not providing state of the art services for this population.

Abstract
INTRODUCTION The subjective experience of drug craving is a prominent and common clinical phenomenon for many individuals diagnosed with opioid use disorder (OUD), and could be a valuable clinical endpoint in medication development studies. The purpose of this scoping review is to provide an overview and critical analysis of opioid craving assessments located in the published literature examining OUD. METHOD Studies were identified through a search of PubMed, Embase, and PsychInfo databases and included for review if opioid craving was the focus and participants were diagnosed with or in treatment for OUD. RESULTS Fifteen opioid craving assessment instruments were identified across the 87 studies included for review. The most common were the Visual Analog Scale (VAS, 41 studies), Desires for Drug Questionnaire (DDQ, 12 studies), Heroin Craving Questionnaire (HCQ, 10 studies), and Obsessive-Compulsive Drug Use Scale (OCDUS, 10 studies). Craving assessments varied considerably in their format, content, time frame, and underlying subscales, and only 6 of 15 had been psychometrically evaluated. DISCUSSION This review identified a variety of opioid craving assessments, but few had been evaluated for their psychometric properties making it difficult to ascertain whether craving is being assessed optimally in studies of OUD. Thus, the development of a reliable and valid opioid craving assessment would be worthwhile and could be guided by recently published Food and Drug Administration Clinical Outcome Assessment (COA) guidelines. Importantly, a COA focused on opioid craving could be a valuable addition to research studies designed to evaluate novel treatments for OUD.

Abstract
BACKGROUND Understanding mechanisms of physiological opioid withdrawal symptoms can inform treatment strategies. This secondary analysis evaluated the association between mydriasis (dilated pupils), a commonly-assessed opioid withdrawal metric, with self- and observer-rated opioid withdrawal severity. METHOD Ninety-five participants with opioid physical dependence were stabilized with morphine before receiving an injection of the opioid antagonist naloxone to precipitate withdrawal. Pupil diameter, the Subjective Opiate Withdrawal Scale (SOWS), and the Clinical Opiate Withdrawal Scale (COWS) were collected at baseline and in 15-minute intervals for 120 min following naloxone administration. Pearson product-moment correlations and linear regressions characterized the relationships between pupil measurements (baseline and peak naloxone-induced) and self- and observer-rated measures of withdrawal. Repeated-measures ANOVAs tested whether self and observer-rated withdrawal severity corresponded to unique patterns in pupil changes. RESULTS Baseline pupil diameter significantly correlated with SOWS and COWS peak scores. Peak naloxone-induced pupil diameter significantly correlated with SOWS scores only. Peak changes in pupil from baseline did not correspond to peak changes in self- and observer-rated withdrawal scales. CONCLUSIONS This study suggests that pupil diameter measurements were more closely associated with acute opioid withdrawal severity than changes in pupil diameter. Prospective research examining the mechanisms underlying the relationship between pupil diameter and opioid withdrawal severity are warranted.

Abstract
Cannabis use disorder (CUD) is prevalent and demand for treatment is increasing, yet few individuals engage in formal treatment and the efficacy of established interventions for CUD is modest. Existing clinical trials evaluating psychosocial and pharmacological treatments for CUD have incorporated a wide variety of measures for assessing cannabis use outcomes, including abstinence, self-reported frequency and quantity used, withdrawal, use/dependence severity, and other psychosocial outcomes. The heterogeneity of measures and outcomes has limited quantitative analyses of the comparative effectiveness of existing interventions. The purpose of this systematic review is to: 1) identify and characterize approaches for measuring cannabis use in existing CUD intervention trials, including abstinence, frequency and quantity of use, and 2) summarize measures used to assess treatment efficacy in other outcome domains (e.g., cannabis use severity, psychosocial functioning, cannabis withdrawal), and provide a platform for future research to evaluate which outcome measures are most likely to reflect treatment efficacy and clinically significant improvement in other outcome domains.

Abstract
BACKGROUND Sustained abstinence is currently the only accepted end-point for pharmacotherapy trials for most substance use disorders (SUD), with the exception of alcohol. Despite recent efforts, the identification of a non-abstinence alternative as a clinically meaningful end-point for drug use trials has been elusive. ARGUMENT AND ANALYSIS The current standard for establishing a clinically meaningful outcome in SUD trials is to demonstrate that a reduction in drug use is associated with improvement in long-term functioning, but data indicate relatively weak associations between drug use and various psychosocial problem domains. This may be because assessments used most commonly to measure an individual's functioning do not specify whether aspects of functioning are a direct consequence of drug use. The acceptance of a non-abstinence-based end-point for alcohol use disorder trials was supported in part through associations with reductions in alcohol-related consequences, although measures designed to assess the direct consequences of drug use are rarely included in drug treatment efficacy trials. CONCLUSIONS The field of substance use disorders should include measures of negative psychosocial and health consequences of drug use, as opposed to overall functioning, in the effort to establish meaningful non-abstinence-based end-points.

Abstract
Background: Tramadol is an opioid-analgesic that has shown epidemiological evidence of abuse. This review evaluates the evidence for tramadol abuse potential in humans. Methods: A systematic literature search for human abuse liability examinations of tramadol was conducted in September 2018 and yielded 13 total studies. Studies were all within-subject, double-blind, placebo-controlled human laboratory comparisons of tramadol to opioid comparators. Results are organized based upon the route of tramadol administration (oral, parenteral) and the participant population (persons with and without current opioid physical dependence). Outcomes were categorized into self-report ratings of positive and negative effects, observer-ratings of effects, time course of effects, likelihood tramadol was identified as an opioid, and tramadol self-administration. Results: Results indicated the relative abuse potential of tramadol was lower than the opioids to which it was compared. Tramadol produced highest positive effect ratings when administered orally to persons with no opioid physical dependence. Relative to other opioids, it produced substantial negative ratings, generally demonstrated a slower onset of effects, and was less likely to be identified by participants as an opioid, though it did produce a higher rate of self-administration relative to other opioids in the one study reporting that outcome. Results suggest that the abuse potential of tramadol is highest when it is administered orally to non-dependent individuals, and that it likely decreases as the dose increased and when it was administered parentally or to persons with opioid physical dependence. Conclusion: Taken together, individuals may be less likely than with other opioids to escalate tramadol doses, transition from oral to parenteral routes of administration, or continue using tramadol once opioid physical dependence develops. In that way, the human abuse potential of tramadol appears to be different from and lower than other opioid analgesic medications.
