Abstract
OBJECTIVE To investigate the association between opioid replacement therapy (ORT) and benzodiazepine (BZD) coprescription and all-cause mortality compared with the prescription of ORT alone. DESIGN Population-based cohort study. SETTING Scotland, UK. PARTICIPANTS Participants were people prescribed ORT between January 2010 and end of December 2020 aged 18 years or above. MAIN OUTCOME MEASURES All-cause mortality, drug-related deaths and non-drug related deaths. SECONDARY OUTCOME ORT continuous treatment duration. ANALYSIS Cox regression with time-varying covariates. RESULTS During follow-up, 5776 of 46 899 participants died: 1398 while on coprescription and 4378 while on ORT only. The mortality per 100 person years was 3.11 during coprescription and 2.34 on ORT only. The adjusted HR for all-cause mortality was 1.17 (1.10 to 1.24). The adjusted HR for drug-related death was 1.14 (95% CI, 1.04 to 1.24) and the hazard for death not classified as drug-related was 1.19 (95% CI, 1.09 to 1.30). CONCLUSION Coprescription of BZDs in ORT was associated with an increased risk of all-cause mortality, although with a small effect size than the international literature. Coprescribing was also associated with longer retention in treatment. Risk from BZD coprescription needs to be balanced against the risk from illicit BZDs and unplanned treatment discontinuation. A randomised controlled trial is urgently needed to provide a clear clinical direction. TRIAL REGISTRATION NUMBER NCT04622995.

Abstract
Though anxiety sensitivity (AS)-fear of anxiety-related experiences-is primarily tied to anxiety vulnerability, AS has also been prospectively associated with general negative affect and depression. Furthermore, depression has been longitudinally associated with different forms of substance use, and some AS subfactors (e.g., cognitive concerns) have been associated more consistently with depression and substance use than others. However, no previous study has investigated if longitudinal associations of AS with substance use may be mediated by depression or whether aspects of AS may be prospectively associated with substance use among adolescents. Hence, the present study tested depressive affect (the negative affective aspect of depression) as a prospective mediator of AS associations with substance use and examined longitudinal AS subfactor associations with substance use and problems. High school 9th graders (N = 2,877; Mage = 14.1 years; 55.3% female) completed self-report measures at baseline and at 6 months and 1 year later. Depressive affect mediated AS associations with subsequent alcohol, cigarette, electronic cigarette, cannabis, benzodiazepine, and opioid use. Also, AS cognitive and social concerns (vs. physical concerns) were more consistently associated with later depressive affect and substance use and problems. Current findings suggest that adolescents high in anxiety sensitivity tend to prospectively experience greater depressive affect, which in turn is related to a higher likelihood of engaging in several different forms of substance use. Thus, it is possible that interventions which target AS (particularly AS cognitive concerns) may help to treat or prevent depression and substance use among adolescents.

Abstract
BACKGROUND Co-use of benzodiazepines and opioids significantly increases fatal overdose risk, yet few studies have examined co-use of these drugs when obtained both with and without a prescription. We examined associations of daily co-use of prescribed benzodiazepines/tranquilizers (BZD/TRQ) and prescribed and nonprescribed opioids among people who use street opioids (PWUO). METHODS PWUO (N = 417) were recruited from Baltimore City and neighboring Anne Arundel County, Maryland, and surveyed on sociodemographic characteristics, structural vulnerabilities, healthcare access and utilization, substance use, and overdose experiences. Multivariable logistic regression was used to identify factors associated with self-reported co-use. RESULTS Participants were 46 years old on average, and predominantly Black (74%) males (62%). Daily co-use was reported by 22%. In multivariable analyses, odds of co-use were significantly higher among participants who did not have a high school degree/GED (adjusted odds ratio [aOR]: 1.71, 95% confidence interval [CI]: 1.02-2.88), endorsed receiving mental health treatment in the past 6 months (aOR: 2.13, 95% CI: 1.28-3.56), reported daily use of powdered cocaine (aOR: 3.57, 95% CI: 1.98-6.45), and synthetic cannabinoids (aOR: 3.11, 95% CI: 1.40-6.93). Odds of co-use were significantly lower among Black participants compared to white participants (aOR: 0.39, 95% CI: 0.19-0.82). CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE Clinicians working with PWUO or who prescribe BZDs or opioids should screen patients who use cocaine or synthetic cannabinoids, have low level of educational attainment, or recently accessed mental health services, as these patients may be at higher risk for daily co-use of BZD/TRQ and opioids, and therefore lethal overdose.

Alprazolam misuse: Analysis of French Addictovigilance Network data from 2011 to 2020. Therapie 2023; 78:647-657. [PMID: 36918317 DOI: 10.1016/j.therap.2023.02.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2022] [Revised: 01/17/2023] [Accepted: 02/09/2023] [Indexed: 02/17/2023]
Abstract
OBJECTIVES Alprazolam, a high-potency and short-acting anxiolytic benzodiazepine, is one of the most misused benzodiazepines in France. In the context of various reports on alprazolam misuse during the COVID-19 pandemic, the objective of this study was to assess alprazolam abuse potential by analyzing French addictovigilance and international data. METHODS Data collected from 2011 to 2020 using the following epidemiological tools of the French Addictovigilance Network were analyzed: spontaneous reports (SRs), OPPIDUM (addiction care center data), OSIAP (falsified prescriptions), DRAMES (substance-related deaths), and chemical submission surveys. Moreover, the VigiBase™ database was analyzed to evaluate alprazolam abuse liability worldwide. RESULTS During the study period, 675 SRs concerning alprazolam misuse were recorded (sex ratio: ̴1; median age: 39 years). The desired effects were intensification of the therapeutic anxiolytic effect, euphoric effect, and management of substance withdrawal. Alprazolam was the third and first benzodiazepine listed in OPPIDUM and OSIAP surveys. Analysis of the SR and OPPIDUM data showed a recent increase in the alprazolam-opioid combination. In DRAMES data, alprazolam was directly linked to 11 deaths (associated with opioids in 10/11). VigiBase™ data analysis highlighted that France was the third country with the most cases of alprazolam misuse. The disproportionality analysis showed that in France, alprazolam was associated with higher risk of misuse and dependence compared with other benzodiazepines: reporting odds ratio=1.43, (95% CI: 1.04-1.95) and=1.97 (95% CI:1.50-2.59), respectively. CONCLUSIONS This study highlighted an increase in various signals of alprazolam abuse in France, and an increased use of the alprazolam-opioid combination that was also linked to most of the recorded alprazolam-linked deaths. These signals have been reported also in the international literature, and should be thoroughly investigated.

Benzodiazepine use, quality of life and psychiatric symptom burden in oral and injectable opioid agonist treatment: a cross-sectional study. Addict Sci Clin Pract 2023; 18:43.

Abstract
BACKGROUND Use of benzodiazepines (BZD) in patients receiving opioid agonist treatment (OAT) is common and associated with a variety of negative health and social outcomes. This cross-sectional study investigates the impact of BZD use in OAT patients on their quality of life (QoL). METHODS A convenience sample of patients receiving oral OAT or heroin-assisted treatment in two outpatient centres in Basel, Switzerland was investigated. Participants (n = 141) completed self-report questionnaires on psychiatric symptoms and psychological distress (The Symptom Checklist 27, SCL-27), depressive state (German version of the Center for Epidemiological Studies Depression Scale), quality of life (Lancashire Quality of Life Profile, LQOLP) and use of BZD and other drugs (self-report questionnaire). Substance use was assessed by urine toxicology testing. RESULTS In bivariate analysis, total QoL scores were significantly lower for lifetime, current, and prolonged BZD users compared to participants without the respective use patterns. There was no significant relationship between BZD dose and QoL. In multivariable linear regression models controlling for psychiatric symptom load and depressive state, only lifetime use predicted lower QoL, whereas other BZD use patterns were not significantly associated. CONCLUSIONS The association of lower QoL and BZD use in OAT patients is strongly confounded by co-occurring depressive state and psychiatric symptoms. Careful diagnosis and treatment of co-occurring mental disorders in OAT is paramount to improve QoL in this patient population and may also help reduce BZD use.

Abstract
Background Dependence on prescription drugs and illicit drugs imposes a global health and social burden. Despite accumulating evidence of prescription drugs and illicit drugs dependence, none of the systematized studies has explored the magnitude of this problem in Pakistan. The aim is to investigate the extent and associated factors of prescription drug dependence (PDD), as opposed to concomitant prescription drug dependence and illicit drug use (PIDU), within a sample of individuals seeking addiction treatment. Methods The cross sectional study was conducted on the sample recruited from three drug treatment centers in Pakistan. Face-to-face interviews were conducted with participants who met ICD-10 criteria for prescription drug dependence. Several aspects like substance use histories, negative health outcomes, patient attitude, pharmacy and physician practices also collected to predict the determinants of (PDD). Binomial logistic regression models examined the factors associated with PDD and PIDU. Results Of the 537 treatment seeking individuals interviewed at baseline, close to one third (178, 33.3%) met criteria for dependence on prescription drugs. The majority of the participants were male (93.3%), average age of 31 years, having urban residence (67.4%). Among participants who met criteria for dependence on prescription drugs (71.9%), reported benzodiazepines as the most frequently used drug, followed by narcotic analgesics (56.8%), cannabis/marijuana (45.5%), and heroin (41.5%). The patients reported alprazolam, buprenorphine, nalbuphine, and pentazocin use as alternatives to illicit drugs. PDD was significantly negatively associated with injectable route (OR = 0.281, 95% CI, 0.079-0.993) and psychotic symptoms (OR = 0.315, 95% CI, 0.100, 0.986). This implies that PDD is less likely to be associated with an injectable route and psychotic symptoms in contrast to PIDU. Pain, depression and sleep disorder were primary reasons for PDD. PDD was associated with the attitude that prescription drugs are safer than illicit drugs (OR = 4.057, 95%CI, 1.254-13.122) and PDD was associated with being on professional terms (i.e., having an established relationship) with pharmaceutical drugs retailers for acquisition of prescription drugs. Discussion and conclusion The study found benzodiazepine and opioid dependence in sub sample of addiction treatment seekers. The results have implications for drug policy and intervention strategies for preventing and treating drug use disorders.

Abstract
OBJECTIVES We aimed to examine trial feasibility plus physiological and psychological effects of a guided meditation practice, Yoga Nidra, in adults with self-reported insomnia. METHODS Twenty-two adults with self-reported insomnia were recruited to attend two visits at our research center. At Visit 1 (V1), participants were asked to lie quietly for ninety minutes. The primary outcome was change in electroencephalography (EEG). Heart rate variability (HRV), respiratory rate and self-reported mood and anxiety were also measured. At Visit 2 (V2), the same protocol was followed, except half of participants were randomized to practice Yoga Nidra for the first 30-min. RESULTS There were no between-group changes (V1-V2) in alpha EEG power at O1 (Intervention: 13 ± 70%; Control: -20 ± 40%), HRV or sleep onset latency in response to Yoga Nidra. Respiratory rate, however, showed statistically significant difference between groups (Yoga Nidra -1.4 breaths per minute (bpm) change during and - 2.1 bpm afterwards vs. Control +0.2 bpm during and + 0.4 bpm after; p = .03 for both during and after). The intervention displayed good acceptability (well-tolerated) and credibility (perceived benefit ratings) with implementation success (target sample size reached; 5% dropout rate). CONCLUSIONS This preliminary clinical trial provides early evidence that Yoga Nidra is a well-tolerated, feasible intervention for adults reporting insomnia. Decreased respiratory rate in response to Yoga Nidra needs to be confirmed in more definitive studies. TRIAL REGISTRATION INFORMATION This trial was registered on ClinicalTrials.gov as "A Closer Look at Yoga Nidra: Sleep Lab Analyses" (NCT#03685227).

Abstract
BACKGROUND Open-access opioid treatment programs (OTP) offer same-day access to methadone without an appointment and aim to minimize treatment barriers that often reduce admission and/or retention. We explored whether patients with benzodiazepine exposure at treatment entry would have similar 12-month retention compared to those without benzodiazepine exposure. METHODS We conducted a retrospective cohort study of 2968 patients consecutively initiated on methadone between January 2015 and February 2017 at an open-access OTP. The sample was stratified into benzodiazepine-exposed and nonexposed groups based on intake urine toxicology. Group comparison of 12-month retention was conducted. Kaplan Meier analysis compared time to methadone treatment discontinuation between groups with a log-rank test. Multivariable Cox regression was performed to compare retention by baseline benzodiazepine exposure with adjustment for confounders. RESULTS Overall, 31% of patients with benzodiazepine exposure (n = 171) and 31% without exposure (n = 2423) were retained at 12 months (p = 0.95). Median treatment duration was 182 days (95% CI, 152-239) and 175 days (95% CI, 156-196) for patients with and without benzodiazepine exposure, respectively. Kaplan-Meier analysis showed no significant difference in treatment duration between groups (log-rank test p = 0.73). Cox regression found no difference in treatment retention between groups (adjusted Hazard Ratio= 1.03, 95% CI, 0.91-1.16). CONCLUSIONS In this cohort of patients receiving methadone at an open-access OTP, benzodiazepine exposure at intake was not observed to impact 12-month treatment retention or duration. These findings support U.S. Food and Drug Administration (FDA) recommendations to not withhold medications for opioid use disorder from patients taking benzodiazepines.

Abstract
Given the increase in benzodiazepine (BZD) and Z-drug (ZD) use disorder, this study described the use of phenobarbital (PHB) as detoxification in clinical practice. A 15-year observational retrospective study was performed on medical records of BZD-ZD use disorder patients detoxified with PHB at the Toxicology Unit and Poison Centre, Careggi University Hospital, Florence (Italy). A multivariate logistic regression was used to estimate odd ratios (ORs) and related 95% confidence intervals (CI) of "treatment failure" considering demographic and pharmacological characteristics. "Hospitalisation length", "PHB discharge dose", and "BZD-ZD free status" at discharge were also calculated. During detoxification, out of 355 patients (57% of men), with a mean age of 42.92 years, only 20 (5.6%) treatment failures were recorded: 19 were discharged against medical advice or due to misbehaviour, and only one for PHB-related non-serious skin rash. Analysis showed a higher probability to be BZD-ZD free at discharge for subjects who reported to be employed (OR 2.29; CI 95% 1.00-5.24), for those who abused oral drops of BZD-ZD (OR 2.16, CI 1.30-3.59), and for those treated with trazodone (OR 2.86, CI 1.14-7.17) during hospital stay. A hospitalisation length of > 7 days was observed for patients with opioid maintenance therapy (OR 2.07, CI 1.20-3.58) for substance use disorder, and for those treated with more than 300 mg/day of PHB equivalents at hospital admission (OR 1.68, CI 1.03-2.72). Our results suggested that PHB can be considered a valuable detoxification option for different types of BZD and ZD use disorder patients.

Trends in opioid analgesic utilisation among people with a history of opioid dependence. Drug Alcohol Depend 2022; 238:109548. [PMID: 35841733 DOI: 10.1016/j.drugalcdep.2022.109548] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2022] [Revised: 06/23/2022] [Accepted: 06/27/2022] [Indexed: 11/22/2022]
Abstract
BACKGROUND We aimed to characterise opioid analgesic utilisation over a 16-year period among a cohort of people with a history of opioid dependence, comparing rates of use in and out of opioid agonist treatment (OAT). METHODS Retrospective cohort study in New South Wales, Australia, including 28,891 people with documented opioid dependence initiating opioid analgesics between July 2003 and December 2018. Linked administrative records provided data on prescription dispensings, sociodemographics, clinical characteristics, and OAT. Generalised estimating equation models estimated the incidence and adjusted incidence rate ratios (IRR) comparing periods in and out of OAT for the number of opioid analgesic dispensings (overall, for strong opioids, and the most commonly dispensed opioid types) and the amount dispensed in oral morphine equivalent milligrams (OME). RESULTS At initiation, 43.7% of the cohort were enrolled in OAT. The most commonly initiated opioid was codeine (including combinations with paracetamol; 67.8%), and 49.6% of the cohort were dispensed a psychotropic medicine in the previous 90 days. Incidence of all opioid analgesic dispensings was higher during periods out of OAT compared to in OAT (5.8 v. 2.3 dispensings per person-year; IRR 0.39, 95% CI 0.38, 0.41), with findings similar when stratified by type. Being in OAT was associated with a lower OME amount dispensed compared to out of OAT (-57.7%, 95% CI-58.8, -56.7). CONCLUSIONS People with opioid dependence had high rates of recent psychotropic medicine utilisation and current OAT enrolment at the time of opioid analgesic initiation. OAT was associated with a significant reduction in opioid analgesic dispensing.

Abstract
The current study examined the relationship between PTSD and nonmedical use of benzodiazepines (BZDs) based on level of John Henry Active Coping (JHAC) among African American incarcerated men. Data were derived from the Helping Incarcerated Men (HIM) Study (n = 208). Nonmedical use of BZDs was measured for the 30 days before incarceration. Current PTSD diagnosis and JHAC were determined using DSM-5 criteria and the JHAC Scale. Adjusted logistic regression analyses showed PTSD diagnosis was significantly associated with nonmedical BZD use (p = .011), but that JHAC did not significantly mitigate this relationship. African American incarcerated men may experience an unmet need with regards to mental health treatment.

Medical Psychotropics in Forensic Autopsies in European Countries: Results from a Three-Year Retrospective Study in Spain. TOXICS 2022; 10:toxics10020064. [PMID: 35202250 PMCID: PMC8876624 DOI: 10.3390/toxics10020064] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/13/2022] [Revised: 01/25/2022] [Accepted: 01/29/2022] [Indexed: 12/21/2022]
Abstract
Medical psychotropics are widely used and prescribed in developed countries. These medications may have an impairing effect on mood or perception and may induce harmful behaviors. Nevertheless, in Europe, studies on their importance from a medico-legal perspective are scarce. To fill this gap, we evaluate the determinants of these drugs in a retrospective study based on data obtained from forensic autopsies. Toxicological analyses were performed on 394 blood samples from compulsory autopsies at the Institute of Legal Medicine of Las Palmas. Of the samples, 41% (159) were positive for at least one psychotropic, with benzodiazepines being the most frequently detected (24.1%), followed by opiates and antidepressants. Benzodiazepines, opiates, and antidepressants were detected more frequently in men who suffered a violent death. More than 30% of the positive samples showed two or more drugs, suggesting a prevalence of polypharmacy among forensic autopsy subjects, with the most frequently combination found being benzodiazepines plus opiates (28.3% of positive samples). A combination of opiates plus antidepressants was also found in subjects involved in violent deaths. Our results suggest that more than 40% of the adult European population involved in medico-legal issues may be under the influence of legal psychotropics. The link between violent deaths and the use of medical psychotropics is particularly worrisome and indicates that these drugs should be carefully monitored in developed countries, in all forensic autopsies, in a similar way to illegal psychotropics.

"It could potentially be dangerous... but nothing else has seemed to help me.": Patient and clinician perspectives on benzodiazepine use in opioid agonist treatment. J Subst Abuse Treat 2021; 131:108455. [PMID: 34098286 DOI: 10.1016/j.jsat.2021.108455] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2021] [Revised: 04/26/2021] [Accepted: 04/26/2021] [Indexed: 10/21/2022]
Abstract
BACKGROUND Benzodiazepine use among patients receiving opioid agonist treatment (OAT) presents a conundrum: benzodiazepines increase overdose risk, yet can treat anxiety and insomnia. How best to balance the risks and benefits of benzodiazepines among OAT patients is unclear. Using qualitative methods, we examined patient motivations for benzodiazepine use and understanding of risks, and the context in which benzodiazepine use and prescribing occurs. METHODS We conducted semi-structured interviews with 26 OAT patients using benzodiazepines and 10 OAT clinicians. Participants were recruited from an office-based buprenorphine clinic at an academic medical center and a methadone opioid treatment program using purposive sampling. The study team reviewed transcripts and double-coded 100% of interviews. Data analysis combined both deductive and inductive methods. RESULTS Major emergent themes were: 1) patients focus on benefits over risks of benzodiazepines, 2) patients can learn to use benzodiazepines safely, 3) patients want to use benzodiazepines now but discontinue in the future, 4) clinicians and patients weigh the risks and benefits of benzodiazepine use differently, 5) clinicians and patient have differences in treatment goals, and 6) clinicians struggle with benzodiazepine discontinuation. CONCLUSIONS OAT patients and clinicians can weigh the risks and benefits of benzodiazepines differently leading to a difference in treatment goals. The risk-benefit analysis of benzodiazepine prescribing may depend on whether the patient is engaged in opioid treatment. Future work among patients and clinicians is warranted to determine how to better balance patient and clinician priorities in order to deliver safer prescribing practices and maintain patient engagement in care.

Abstract
To study the prevalence of perceived high stress among methadone maintenance treatment (MMT) patients, and whether stress can predict outcome, and whether stress may improve during treatment, we studied a sample of 107 MMT patients using Perceived Stress Scale (PSS) questionnaires. We studied if PSS scores on admission predict long-term retention, and we monitored stress indices (PSS, heart rate variability, saliva cortisol) on admission, 6 and 12 months later, to measure changes. Variables included demographic data, history of adverse events, and urine test. A sample of 79 (73.8%) males and 28 (26.2%) females whose age at opioid use onset was 22.1±7.2 years and age at study onset 50.5±10.8 years was studied for PSS. Both high and very-high PSS patients characterized (logistic regression) as abusing benzodiazepine, and with history of depressive symptoms. The very-high PSS group on admission (n=29) had shorter cumulative retention (1.8 years, 95%%CI 1.2-2.4) compared with 50 others (2.8 years, 95%%CI 2.3-3.3, p=0.03). Monitoring stress indices among 25 patients found that no-benzodiazepine and cocaine use on admission, opioid discontinuation after 6 months, and any substance discontinuation after a year were associated with stress reduction. Conclusion: stress level appears to normalize among MMT patients if no other substance is abused.

Abstract
BACKGROUND Nonmedical Prescription Drug Use (NMPDU) is common among people who use illegal drugs. NMPDU is particularly problematic among this population however, as medications such as benzodiazepines and gabapentinoids can potentiate the harmful effects of opioids. Despite these harms, there is some evidence that NMPDU can have harm reducing and therapeutic potential for some people who use illegal drugs. This study provides further evidence of the harm reducing motives for NMPDU among people who use illegal drugs in community and prison settings in Wales, UK. METHODS In depth, semi-structured interviews were conducted with 60 interviewees recruited from statutory and third sector drug treatment providers operating in five towns and cities in Wales, and from two Welsh prisons. Eligibility was based primarily on whether the person was currently (or previously) a user of illegal drugs and had recent experience of NMPDU. RESULTS NMPDU was found to be largely driven by insufficient access to certain prescription medications and treatment. In this context, NMPDU played an important role in alleviating legitimate medical concerns and overcoming logistical and regulatory barriers associated with Opioid Substitution Therapy. NMPDU also had everyday practicality and mitigated many of the everyday harms experienced by people who use drugs, including opioid withdrawal and stimulant comedowns. CONCLUSION Results suggest that NMPDU has the potential to mitigate a number of legitimate medical concerns in the absence of treatment. Finding nuanced ways of responding to patient need whilst reducing the potential for NMPDU are therefore needed, and harm reduction strategies that harness the knowledge and expertise of people who use drugs should be encouraged. Additional policy measures that attend to the inequities and social-structural factors that produce and maintain the need to consume prescription medications in ways that are not intended are also required.

Addiction 2020; 115:924-932. [PMID: 31916306 PMCID: PMC7156323 DOI: 10.1111/add.14886] [Citation(s) in RCA: 40] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/04/2019] [Revised: 05/23/2019] [Accepted: 10/29/2019] [Indexed: 12/23/2022]
Abstract
BACKGROUND AND AIMS Benzodiazepines are commonly prescribed to patients with opioid use disorder receiving buprenorphine treatment, yet may increase overdose risk. However, prescribed benzodiazepines may improve retention in care by reducing buprenorphine discontinuation and thus may prevent relapse to illicit opioid use. We aimed to test the association between benzodiazepine prescription and fatal opioid overdose, non-fatal opioid overdose, all-cause mortality and buprenorphine discontinuation. DESIGN AND SETTING This was a retrospective cohort study using five individually linked data sets from Massachusetts, United States government agencies. PARTICIPANTS We studied 63 389 Massachusetts residents aged 18 years or older who received buprenorphine treatment between January 2012 and December 2015. MEASUREMENTS Filled benzodiazepine prescription during buprenorphine treatment was the main independent variable. The primary outcome was time to fatal opioid overdose. Secondary outcomes were time to non-fatal opioid overdose, all-cause mortality and buprenorphine discontinuation. We defined buprenorphine discontinuation as having a 30-day gap without another prescription following the end date of the previous prescription. We used Cox proportional hazards models to calculate hazards ratios that tested the association between receipt of benzodiazepines and all outcomes, restricted to periods during buprenorphine treatment. FINDINGS Of the 63 345 individuals who received buprenorphine, 24% filled at least one benzodiazepine prescription during buprenorphine treatment. Thirty-one per cent of the 183 deaths from opioid overdose occurred when individuals received benzodiazepines during buprenorphine treatment. Benzodiazepine receipt during buprenorphine treatment was associated with an increased risk of fatal opioid overdose adjusted hazard ratio (HR) = 2.92, 95% confidence interval (CI) = 2.10-4.06, non-fatal opioid overdose, adjusted HR = 2.05, 95% CI, 1.68-2.50, all-cause mortality, adjusted HR = 1.90, 95% CI, 1.48-2.44 and a decreased risk of buprenorphine discontinuation, adjusted HR = 0.87, 95% CI, 0.85-0.89. CONCLUSIONS Benzodiazepine receipt appears to be associated with both increased risk of opioid overdose and all-cause mortality and decreased risk of buprenorphine discontinuation among people receiving buprenorphine.

THE INTERNATIONAL JOURNAL OF DRUG POLICY 2020; 79:102721.

Abstract
INTRODUCTION Alprazolam is a high potency triazolobenzodiazepine that is associated with a disproportionate amount of harm compared to other benzodiazepines. In Australia, amid growing concerns of extra-medical use and harms, alprazolam was up-scheduled from Schedule 4 (prescription only) to Schedule 8 (controlled drug) on 1 February 2014, with further restrictions introduced on 1 February 2017. This study aims to examine the impact of these regulatory changes among cross-sectional samples of people who inject drugs (PWID), from 2011-2019. METHODS Data were obtained from the 2011-2019 Illicit Drug Reporting System, comprising cross-sectional samples of PWID recruited annually from Australian capital cities (approximately ~900 per year). RESULTS By 2019, the proportion of PWID who reported past six-month use of non-prescribed (17%) and prescribed (4%) alprazolam had halved compared to 2011 (39% and 13%, respectively), with no evidence of an increase in use of other sedative substances. Following the up-scheduling of alprazolam in 2014, there was an increase in the median last price paid for 2 mg of diverted alprazolam ($5AUD pre-rescheduling versus $7AUD post rescheduling), with 61% of those able to answer reporting that diverted alprazolam had become 'more difficult' to obtain post versus pre-rescheduling. The correlates associated with non-prescribed alprazolam use remained relatively consistent pre- and post-regulatory change, with past-month criminal activity, past six-month opioid agonist therapy and past six-month use of non-prescribed other benzodiazepines associated with non-prescribed alprazolam use in both the 2013 and 2018 samples. CONCLUSIONS Regulatory changes appear to have resulted in sustained reductions in alprazolam use amongst our annual cross-sectional sentinel samples of PWID, although a considerable minority (17%) continued to report non-prescribed use in 2019. To achieve further reductions in non-prescribed use and associated harms, these regulatory changes need to be coupled with other interventions, such as direct consumer engagement and harm reduction messaging. Our findings suggest that people receiving opioid agonist therapy remain a key target population for such interventions.

Abstract
OBJECTIVE To examine opioid use, opioid prescribing patterns, and timing of the first opioid prescription in endometriosis patients compared with matched women in the control group without endometriosis. METHODS We conducted a retrospective analysis of the Clinformatics Datamart database. Women diagnosed with endometriosis from January 2006 through December 2016 and aged 18-49 years were compared with women in the control group matched on age, region, race, insurance payer, and plan type. Key outcomes included: filled prescription for an opioid, multiple opioid prescriptions, number of days' supply, daily dose (morphine milligram equivalents), and concomitant opioid and benzodiazepine prescriptions. Cohorts were descriptively analyzed using t- and χ statistics and multivariable regression analyses yielded adjusted relative risk (RR) ratios and 95% CI. RESULTS The study sample included 53,847 endometriosis patients and 107,694 patients in the control group. The mean age was 38 years, 62.4% of patients were white, and 51.6% lived in the South. Women in the endometriosis case group, compared with women in the control group, were more likely to fill an opioid prescription (42,705 [79.3%] women in the case group vs 26,106 [24.2%] women in the control group; adjusted RR ratio 2.91; 2.87-2.94), had higher likelihood of filling prescriptions with a dose of 50 morphine milligram equivalents or more (24,544 [45.6%] vs 10,463 [9.7%]; adjusted RR ratio 4.07; 3.98-4.16) or 100 morphine milligram equivalents or more (8,013 [14.9%] vs 3,582 [3.3%]; adjusted RR ratio 3.56; 3.43-3.70). Women in the case group were more likely to have concomitant opioid and benzodiazepine prescriptions (5,453 [10.1%] vs 3,711 [3.5%]; adjusted RR ratio 1.95; 1.88-2.03) and to have used these drugs concurrently for at least 30 days (1,596 [3.0%] vs 1,265 [1.2%]; adjusted RR ratio 1.43; 1.34-1.52) or at least 90 days (875 [1.6%] vs 777 [0.7%]; adjusted RR ratio 1.27; 1.17-1.37). Similar results were obtained after excluding opioid prescriptions received during a 30-day postsurgery window. CONCLUSION Women with endometriosis had higher probabilities of prolonged use of opioids and concomitant use with benzodiazepines compared with women without this condition.

Abstract
BACKGROUND Benzodiazepine misuse is a growing public health problem, with increases in benzodiazepine-related overdose deaths and emergency room visits in recent years. However, relatively little attention has been paid to this emergent problem. We systematically reviewed epidemiological studies on benzodiazepine misuse to identify key findings, limitations, and future directions for research. METHODS PubMed and PsychINFO databases were searched through February 2019 for peer-reviewed publications on benzodiazepine misuse (e.g., use without a prescription; at a higher frequency or dose than prescribed). Eligibility criteria included human studies that focused on the prevalence, trends, correlates, motives, patterns, sources, and consequences of benzodiazepine misuse. RESULTS The search identified 1970 publications, and 351 articles were eligible for data extraction and inclusion. In 2017, benzodiazepines and other tranquilizers were the third most commonly misused illicit or prescription drug in the U.S. (approximately 2.2% of the population). Worldwide rates of misuse appear to be similar to those reported in the U.S. Factors associated with misuse include other substance use, receipt of a benzodiazepine prescription, and psychiatric symptoms and disorders. Benzodiazepine misuse encompasses heterogeneous presentations of motives, patterns, and sources. Moreover, misuse is associated with myriad poor outcomes, including mortality, HIV/HCV risk behaviors, poor self-reported quality of life, criminality, and continued substance use during treatment. CONCLUSIONS Benzodiazepine misuse is a worldwide public health concern that is associated with a number of concerning consequences. Findings from the present review have implications for identifying subgroups who could benefit from prevention and treatment efforts, critical points for intervention, and treatment targets.

Abstract
BACKGROUND Understanding the association of polydrug use disorders (PUD) with psychosocial and clinical factors is essential for the treatment of individuals with opioid use disorder (OUD). The aim of this study is to examine whether there is an association between childhood maltreatment, mood disorders, anxiety disorders, personality disorders, or posttraumatic stress disorder (PTSD) and PUD in individuals with OUD. METHODS We used data from 356 individuals with OUD in the past 12 months from a nationally representative database in the United States. PUD patients were classified into two groups: a group with additional one substance disorder (OUD + 1) and that with two or more additional substance disorders (OUD + 2). We conducted multivariate logistic regression to predict the PUD status, after adjustment for confounders including childhood maltreatment. RESULTS Among all individuals, 57.3% were polydrug users (n = 204) and 42.7% were not (n = 152). There was a high prevalence of childhood maltreatment in both groups, ranging from 16.1% to 59.5%, but the difference was not statistically significant. After adjustment for confounders, we found an association between past-year PTSD and OUD + 2 (odds ratio: 3.98; 95% confidence interval: 1.15-13.72; p = 0.03) but not with OUD + 1. CONCLUSION PTSD is highly prevalent in individuals with OUD using multiple substances and could influence PUD. We recommend screening for PTSD in cases of PUD. Future studies should evaluate the effect of PTSD treatment on PUD.

Abstract
Background: Insomnia and excessive daytime sleepiness (EDS) are reported to be common in methadone maintenance treatment (MMT) but much less is known about these symptoms in buprenorphine maintenance treatment (BMT) and in women compared with men. Methods: Cross sectional study of recipients of BMT (n = 113, 47 women), MMT (n = 184, 94 women), people using opioids nonmedically (nonopioid agonist treatment, non-OAT: n = 87, 31 women) and a reference group with no opioid use (RG; n = 105, 53 women) in Australia. Measures included Athens Insomnia Scale, Epworth Sleepiness Scale, the Hospital Anxiety and Depression Scale, and other substance use. Results: Insomnia (Athens Insomnia Scale, total ≥10) was highly prevalent among all people who use opioids (BMT 46.0-68.1%; MMT 55.4-69.6%; non-OAT 58.6-80.5%), did not differ significantly among these groups, and was significantly associated with anxiety and depression. EDS (Epworth score >10) was found in 14.2% of BMT, 22.8% of MMT, 35.6% of non-OAT groups, and 11.4% of the RG, and was significantly associated with depression overall. Fewer people had Epworth score >15 indicating more severe EDS (BMT 4.4%, MMT 6.0%; non-OAT 13.8%; RG 1.9%). Insomnia and EDS did not differ by sex or by opioid dose, nor were they significantly associated with other drug use, housing stress or social security status. Conclusions: Insomnia was common in people receiving OAT and using opioids non-medically, and associated with anxiety and depression. Clinicians should consider the possibility of daytime sleepiness in people receiving BMT and MMT, and in people using opioids nonmedically.

Abstract
BACKGROUND The aim of this retrospective study is to use existing epidemiological data on patients in methadone maintenance treatment in Split-Dalmatia County from 2001 to 2015 to evaluate the substitution treatment system and policy of opiate addicts treatment, the epidemiological trend, and risk of overdose mortality. In addition, we would like to highlight the problem of poor control of methadone therapy and thus the possibility of selling methadone. The result is a greater number of deaths caused by methadone in people who were not in methadone therapy. METHODS The research included data collected from 3189 patients who had been in the drug abuse treatment program in Split-Dalmatia County during 2001-2015 and data gathered from autopsy examinations of patients in Split-Dalmatia County with emphasis on data for 186 overdosed patients during research period. RESULTS The total number of patients in the methadone treatment program in Split-Dalmatia County during the research period, except in 2005 and 2006, has been stable, while the number of new opiate patients, being in first-time treatment, decreased by 62.5%. The number of addicts who were in a long-term maintenance program has increased by 198%, whereas the number of addicts who were in a short-term detoxification treatment has decreased by 96.4%. According to results obtained from performed autopsies, 186 death cases were determined as overdoses. Methadone was found in 56 of those cases and was declared as the cause of death in 39 cases (70%). Of the total number of autopsied patients with diagnosed methadone overdose, only 23 (59%) had been recorded to receive methadone therapy in Public Health Institute of Split-Dalmatia County database. CONCLUSIONS The results of this study show the favorable epidemiological trend because of the decreasing number of new opiate patients in treatment. The retention of opiate patients in substitution therapy indicates the effectiveness of methadone maintenance programs. Our research did not determine any influence of methadone substitution therapy on an increasing risk of specific (overdose) mortality.

Abstract
BACKGROUND AND OBJECTIVES Polysubstance use is associated with relapse and poor treatment outcomes among people dependent on heroin. Despite the high prevalence of polysubstance use among patients detoxifying from heroin, little is known about patients' expectations to abstain or use non-opiate substances. The current study examined factors associated with expectations about abstaining from alcohol, cocaine, and benzodiazepines (BZDs) following heroin withdrawal management. METHODS Between May and December of 2015, we surveyed 417 patients (71.9% male, 31.7 [±8.39] mean years old) initiating short-term inpatient heroin withdrawal management who reported alcohol, cocaine, or BZD use in the past 30 days. We used logistic regression to evaluate the adjusted associations of background characteristics with expectations about using each substance following discharge. RESULTS Approximately half of respondents reported past month alcohol (52%), cocaine (47.0%), or BZD (47.0%) use, and 25.9% reported using all three substances. Approximately half of those reporting drinking, 6.6% reporting cocaine use, and 27% of reporting BZD use expected to abstain from using that substance following heroin withdrawal. Prior opioid withdrawal was associated with a lower likelihood of expecting to stop using alcohol and BZDs, and more days of BZD use was associated with a greater likelihood of expecting to abstain from BZDs following discharge. CONCLUSION Persons with opioid use disorder often do not expect to stop using other substances following withdrawal management, with very few planning cocaine cessation. SCIENTIFIC SIGNIFICANCE Inpatient heroin withdrawal programs need to address and educate patients about how polysubstance use complicates recovery from heroin use. (Am J Addict 2019;28:36-42).

Abstract
BACKGROUND AND OBJECTIVES The nonmedical use of benzodiazepines-defined as use without a prescription or at a dose or frequency higher than prescribed-is increasing among adults in substance use disorder treatment and is associated with risk for overdose. The aim of the current study was to characterize the prevalence of nonmedical benzodiazepine use among adults seeking treatment for alcohol use disorder and to examine whether nonmedical benzodiazepine use was associated with: (1) polysubstance use and (2) greater anxiety sensitivity. METHODS A sample of 461 treatment-seeking adults with alcohol use disorder who were recruited for a cross-sectional study were included in this analysis. RESULTS A total of 89 participants (19%) reported nonmedical benzodiazepine use in the previous 30 days. Results of a logistic regression indicated that polysubstance use (number of substances used in the past month) was associated with nonmedical benzodiazepine use. The association between anxiety sensitivity and nonmedical benzodiazepine misuse was moderated by gender; anxiety sensitivity was associated with benzodiazepine use among women, but not men. DISCUSSION AND CONCLUSIONS These results replicate findings from research on opioid use disorder suggesting that anxiety sensitivity is associated with nonmedical benzodiazepine use in women and not men. SCIENTIFIC SIGNIFICANCE Targeted intervention to those with polysubstance use-including education on overdose risk when benzodiazepines are combined with other substances-is indicated in men and women with alcohol use disorder. Anxiety sensitivity may be a potential therapeutic target to reduce nonmedical benzodiazepine use among women with alcohol use disorder. (Am J Addict 2018;27:485-490).

Abstract
BACKGROUND Benzodiazepines (BZDs) are widely prescribed during psychiatric treatment. Unfortunately, their misuse has led to recent surges in overdose emergency visits and drug-related deaths. METHODS Electronic health record data from a large healthcare system were used to describe racial/ethnic, sex, and age differences in BZD use and dependence. Among patients with a BZD prescription, we assessed differences in the likelihood of subsequently receiving a BZD dependence diagnosis, number of BZD prescriptions, receiving only one BZD prescription, and receiving 18 or more BZD prescriptions. We also estimated multivariate hazard models and generalized linear models, assessing racial/ethnic differences after adjustment for covariates. RESULTS In both unadjusted and adjusted analyses, Whites were more likely than Blacks, Hispanics, and Asians to have a BZD dependence diagnosis and to receive a BZD prescription. Racial/ethnic minority groups received fewer BZD prescriptions, were more likely to have only one BZD prescription, and were less likely to have 18 or more BZD prescriptions. We identified greater BZD misuse among older patients but no sex differences. CONCLUSIONS Findings from this study add to the emerging evidence of high relative rates of prescription drug abuse among Whites. There is a concern, given their greater likelihood of having only one BZD prescription, that Blacks, Hispanics, and Asians may be discontinuing BZDs before their clinical need is resolved. Research is needed on provider readiness to offer racial/ethnic minorities BZDs when indicated, patient preferences for BZDs, and whether lower prescription rates among racial/ethnic minorities offer protection against the progression from prescription to addiction.

Abstract
BACKGROUND Benzodiazepine use dramatically increases the risk of unintentional overdose among people who use opioids non-medically. However, little is known about the patterns of co-occurring benzodiazepine and opioid use among young adults in the United States. METHODS The Rhode Island Young Adult Prescription Drug Study (RAPiDS) was a cross-sectional study from January 2015-February 2016. RAPiDS recruited 200 young adults aged 18-29 who reported past 30-day non-medical prescription opioid (NMPO) use. Using Wilcoxon rank sum test and Fisher's exact test, we examined correlates associated with regular prescribed and non-medical use (defined as at least monthly) of benzodiazepines among NMPO users in Rhode Island. RESULTS Among participants, 171 (85.5%) reported lifetime benzodiazepine use and 125 (62.5%) reported regular benzodiazepine use. Nearly all (n=121, 96.8%) reported non-medical use and 43 (34.4%) reported prescribed use. Compared to the 75 participants who did not regularly use benzodiazepines, participants who reported regular use were more likely to be white (66.3% vs. 58.0%, p=0.03), have ever been incarcerated (52.8% vs. 37.3%, p=0.04), and have ever been diagnosed with a psychiatric disorder (bipolar: 29.6% vs. 16.0%, p=0.04; anxiety: 56.8 vs. 36.0%, p=0.01). Although the association was marginally significant, accidental overdose was higher among those who were prescribed the benzodiazepine they used most frequently compared to those who were not (41.9% vs. 24.4%, p=0.06). CONCLUSION Benzodiazepine use and misuse are highly prevalent among young adult NMPO users. Harm reduction and prevention programs for this population are urgently needed.

Abstract
Aims and methodTo examine patients' perceptions of unmet needs during methadone maintenance treatment (MMT), and to explore the relationship between co-occurring benzodiazepine misuse and severity of needs. A cross-sectional survey was carried out at an MMT programme in Dublin, Ireland. All patients were invited to participate on a voluntary basis. Of the 191 eligible patients, 107 agreed to participate and completed the Camberwell Assessment of Need questionnaire.ResultsUnmet needs for substance misuse treatments, daytime activities, socialisation, money management and psychological distress were high. Fifty-two respondents (49%) reported using non-prescribed benzodiazepines during the past month. Compared with non-users of benzodiazepines, benzodiazepine users reported higher ratings of total and unmet needs (P < 0.05). The number of days using benzodiazepines predicted the severity of needs.Clinical implicationsThe findings highlight the importance of addressing coexisting psychological needs, and further support enhancing treatment interventions for benzodiazepine misuse or dependence among patients on MMT.

Abstract
Prescriptions for Benzodiazepines (BZDs) have risen continually. According to national statistics, the combination of BZDs with opioids has increased since 1999. BZDs (sometimes called “benzos”) work to calm or sedate a person by raising the level of the inhibitory neurotransmitter GABA in the brain. In terms of neurochemistry, BZDs act at the GABAA receptors to inhibit excitatory neurons, reducing VTA glutaminergic drive to reduce dopamine release at the Nucleus accumbens. Benzodiazepine Use Disorder (BUD) is very difficult to treat, partly because BZDs are used to reduce anxiety which paradoxically induces hypodopaminergia. Considering this, we are proposing a paradigm shift. Instead of simply targeting chloride channel direct GABAA receptors for replacement or substitution therapy, we propose the induction of dopamine homeostasis. Our rationale is supported by the well-established notion that the root cause of drug and non-drug addictions (i.e. Reward Deficiency Syndrome [RDS]), at least in adults, involve dopaminergic dysfunction and heightened stress. This proposition involves coupling the Genetic Addiction Risk Score (GARS) with a subsequent polymorphic matched genetic customized Pro-Dopamine Regulator known as KB220ZPBM (Precision Behavioral Management). Induction of dopamine homeostasis will be clinically beneficial in attempts to combat BUD for at least three reasons: 1) During detoxification of alcoholism, the potential induction of dopamine regulation reduces the need for BZDs; 2) A major reason for BZD abuse is because people want to achieve stress reduction and subsequently, the potential induction of dopamine regulation acts as an anti-stress factor; and 3) BUD and OUD are known to reduce resting state functional connectivity, and as such, potential induction of dopamine regulation enhances resting state functional connectivity. Future randomized placebo-controlled studies will investigate this forward thinking proposed novel modality.

Abstract
BACKGROUND Polydrug abuse is a known problem among opioid-dependent patients receiving opioid maintenance treatment (OMT). However, improved laboratory diagnostics is required to reveal polydrug abuse in its current scope. Furthermore, there are few studies focusing on the relationship between polydrug abuse and adequacy of the dose of OMT medicine. This study aimed to evaluate the polydrug abuse among opioid-dependent patients receiving OMT with inadequate (Group IA) and adequate (Group A) doses of OMT medicine as experienced by the patients. Craving for opioids and withdrawal symptoms were evaluated as indicators of the adequacy rating. METHODS This is a retrospective register-based study of 60 OMT patients on either methadone or sublingual buprenorphine/naloxone medication, whose polydrug abuse was studied from urine samples by means of a comprehensive high-resolution mass spectrometry method. RESULTS Inadequate doses of the OMT medicines were associated with higher subjective withdrawal scores and craving for opioids. Six groups of abused substances (benzodiazepines, amphetamines, opioids, cannabis, new psychoactive substances, and non-prescribed psychotropic medicines) were found among OMT patients. Group IA patients showed significantly more abuse of benzodiazepines and amphetamines than the Group A patients. All the new psychoactive substances and most of the non-prescribed psychotropic medicines were detected from the Group IA patients. There was no difference in the doses of the OMT medicine between Groups IA and A patients. CONCLUSIONS Polydrug abuse, detected by definitive laboratory methods, was widespread and more common among Group IA than Group A patients, emphasizing the requirement for individual OMT medicine dose adjustment.

High enhancer, downer, withdrawal helper: Multifunctional nonmedical benzodiazepine use among young adult opioid users in New York City. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2017; 46:17-27. [PMID: 28577506 DOI: 10.1016/j.drugpo.2017.05.016] [Citation(s) in RCA: 43] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2016] [Revised: 04/08/2017] [Accepted: 05/03/2017] [Indexed: 11/21/2022]
Abstract
BACKGROUND Benzodiazepines are a widely prescribed psychoactive drug; in the U.S., both medical and nonmedical use of benzodiazepines has increased markedly in the past 15 years. Long-term use can lead to tolerance and dependence, and abrupt withdrawal can cause seizures or other life-threatening symptoms. Benzodiazepines are often used nonmedically in conjunction with other drugs, and with opioids in particular-a combination that can increase the risk for fatal and non-fatal overdose. This mixed-methods study examines nonmedical use of benzodiazepines among young adults in New York City and its relationship with opioid use. METHODS For qualitative analysis, 46 90-minute semi-structured interviews were conducted with young adult opioid users (ages 18-32). Interviews were transcribed and coded for key themes. For quantitative analysis, 464 young adult opioid users (ages 18-29) were recruited using Respondent-Driven Sampling and completed structured interviews. Benzodiazepine use was assessed via a self-report questionnaire that included measures related to nonmedical benzodiazepine and opioid use. RESULTS Participants reported using benzodiazepines nonmedically for a wide variety of reasons, including: to increase the high of other drugs; to lessen withdrawal symptoms; and to come down from other drugs. Benzodiazepines were described as readily available and cheap. There was a high prevalence (93%) of nonmedical benzodiazepine use among nonmedical opioid users, with 57% reporting regular nonmedical use. In bivariate analyses, drug-related risk behaviours such as polysubstance use, drug binging, heroin injection and overdose were strongly associated with regular nonmedical benzodiazepine use. In multivariate analysis, growing up in a middle-income household (earning between $51,000 and $100,000 annually), lifetime overdose experience, having ever used cocaine regularly, having ever been prescribed benzodiazepines, recent drug binging, and encouraging fellow drug users to use benzodiazepines to cope with opioid withdrawal were consistently strong predictors of regular nonmedical benzodiazepine use. CONCLUSION Nonmedical benzodiazepine use may be common among nonmedical opioid users due to its drug-related multi-functionality. Harm reduction messages should account for the multiple functions benzodiazepines serve in a drug-using context, and encourage drug users to tailor their endorsement of benzodiazepines to peers to include safer alternatives.

Abstract
Increased abuse of opioids is contributing to an escalation in overdose deaths. Benzodiazepines are frequently abused with opioids, possibly because they increase the potency and/or effectiveness of opioids to produce reinforcing effects. This study used a concurrent-choice procedure to determine whether monkeys would choose to self-administer a mixture of the opioid remifentanil and the benzodiazepine midazolam over remifentanil alone. Initially, three monkeys could respond on one lever for saline and on a second lever for either remifentanil alone or midazolam alone. Thereafter, monkeys chose between a dose of remifentanil (0.32 µg/kg/infusion) that did not change and a dose of remifentanil that varied across sessions; for some sessions, midazolam was combined with varying doses of remifentanil. All monkeys received more infusions of remifentanil (0.0032-0.32 µg/kg/infusion) than saline, whereas only two monkeys responded more for midazolam than for saline. When 0.32 µg/kg/infusion remifentanil was available on one lever and a dose of remifentanil that varied across sessions (0.1-1 µg/kg/infusion) was available on the other lever, monkeys chose the larger dose. Combining 3.2 µg/kg/infusion midazolam with 0.32 µg/kg/infusion remifentanil increased responding for the mixture over 0.32 µg/kg/infusion remifentanil alone, although monkeys chose remifentanil alone over mixtures containing smaller doses of remifentanil. When 10 µg/kg/infusion midazolam was combined with 0.1 µg/kg/infusion remifentanil, monkeys chose the mixture over 0.32 µg/kg/infusion remifentanil alone. Thus, monkeys prefer some opioid/benzodiazepine mixtures to larger doses of the opioid alone, suggesting that opioid/benzodiazepine coabuse might be due to increased potency (and possibly effectiveness) of opioids to produce reinforcing effects.

Abstract
BACKGROUND Patients admitted to addiction treatment programs report high rates of concurrent opioid and benzodiazepine (BZD) use. This combination places individuals at high risk for accidental overdose and other serious consequences. However, little is known about the beliefs opioid users have about the consequences of BZD use. METHODS We surveyed consecutive persons initiating inpatient opioid detoxification (N=476; 95.0% enrollment) and identified 245 who reported BZD use in the past 30days and/or had a positive toxicology. We compared those who did and did not report BZD use on demographic and substance use variables, and specific beliefs about the potential effects of BZDs. RESULTS Participants averaged 32.2years of age, 71.2% were male, 86.6% used heroin, and 68.7% reported injection drug use in the past 30days. Over half (51.5%) used a BZD in the month prior to admission; of these, 26.2% (n=64) reported being prescribed a BZD. Alprazolam (Xanax) was the most commonly used BZD (54%). Benzodiazepine users (versus non-users) were significantly more likely to be female and non-Hispanic White, use concurrent substances, and report past year overdose. Overall, nearly all BZD users endorsed accurate beliefs that BZDs can increase the risk of overdose and can be addictive. However, BZD users, relative to non-users, were significantly less likely to endorse some known adverse consequences of BZDs, such as risk of worsening depression and poor medication-assisted opioid treatment retention. CONCLUSIONS Delineating the full array of risks from combining BZDs and opioids should be a high priority in detoxification settings, given the increased risks associated with BZD misuse in this population.

Anxiety sensitivity and nonmedical benzodiazepine use among adults with opioid use disorder. Addict Behav 2017; 65:283-288.

Abstract
Nonmedical benzodiazepine use is common among adults with opioid use disorder; however, little is known about this co-occurrence. Anxiety sensitivity-the fear of anxiety symptoms and sensations-motivates behaviors to escape and avoid distressing states, and accordingly is associated with coping motives for substance use. This might be particularly relevant among women, who report using substances to cope with negative emotions more often than men. The aim of the current study was to examine whether nonmedical benzodiazepine use was associated with higher anxiety sensitivity among treatment-seeking adults diagnosed with opioid use disorder, and to investigate whether gender moderated this association. A sample of adults (ranging in age from 18 to 81years) receiving inpatient treatment for opioid use disorder (N=257) completed measures of anxiety, anxiety sensitivity, and benzodiazepine use frequency. Results of an analysis of variance indicated that frequency of past-month nonmedical benzodiazepine use was associated with significantly higher anxiety sensitivity. This effect remained when controlling for the effect of anxiety symptoms (F[1, 251]=3.91, p=0.049, ηp2=0.02). Gender moderated this association, and post-hoc analyses found a strong association between nonmedical benzodiazepine use and anxiety sensitivity in women, and not men. Anxiety sensitivity, which can be reduced with treatment, might be a candidate therapeutic target in this population, particularly in women.

Abstract
Background Benzodiazepine use is common among patients in opioid agonist therapy; this puts patients at an increased risk of overdose and death. In this study, we examine the impact of baseline and ongoing benzodiazepine use, and whether patients are more likely to terminate treatment with increasing proportion of benzodiazepine positive urine samples. We also study whether benzodiazepine use differs by geographic location. Methods We conducted a retrospective cohort study using anonymized electronic medical records from 58 clinics offering opioid agonist therapy in Ontario. One-year treatment retention was the primary outcome of interest and was measured for patients who did and did not have a benzodiazepine positive urine sample in their first month of treatment, and as a function of the proportion of benzodiazepine-positive urine samples throughout treatment. Cox proportional hazard model was used to characterize one-year retention. Results Our cohort consisted of 3850 patients, with the average retention rate of 43.4%. Baseline benzodiazepine users had a retention rate of 39.9% and non-users had a retention rate of 44%. Patients who were benzodiazepine negative on admission benefited from an increased median days retained of 265 vs. 215 days. Patients with more than 75% of urines positive for benzodiazepines were 175% more likely to drop out of treatment than those patients with little or no benzodiazepine use. Conclusions Baseline benzodiazepine use is predictive of decreased retention. Patients who have a higher proportion of benzodiazepine-positive urine samples are more likely to drop out of treatment compared to those who have little or no benzodiazepine detection in their urine.

Abstract
Benzodiazepines (BZDs) are among the most widely prescribed drugs in developed countries, but they have a high potential for tolerance, dependence and misuse. High-dose BZD misuse represents an emerging addiction phenomenon, but data on quality of life (QoL) in high-dose BZD misusers are scant. This study aimed to explore QoL in high-dose BZD misuse. We recruited 267 high-dose BZD misusers, compared the QoL scores in those who took BZD only to poly-drug misusers, and explored the role of demographic and clinical covariates through multivariable analysis. Our data confirmed worse QoL in high-dose BZD misusers and showed that (a) QoL scores were not negatively influenced by the misuse of alcohol or other drugs, or by coexisting psychiatric disorders; (b) demographic variables turned out to be the most significant predictors of QoL scores; (c) BZD intake significantly and negatively influenced QoL. Physical and psychological dimensions of QoL are significantly lower in high-dose BZD misusers with no significant effect of comorbidities. Our data suggest that the main reason for poor QoL in these patients is high-dose BZD intake per se. QoL should be considered among outcome measures in these patients.

Abstract
BACKGROUND Co-prescribing benzodiazepines to patients in opiate substitution treatment is controversial and often alleged to increase mortality. In an inner-London general practice, patients with problematic benzodiazepine co-dependence were allowed benzodiazepine maintenance treatment (BMT) since 1994, providing an opportunity for analysis. METHOD 1) Case-note review of all 278 opiate substitution treatment patients, accruing 1289 patient treatment years; 46% had concurrent BMT. 2) National Health Service database search for patients who died after leaving accrued a further 883 years of information; only patients who left the UK were unaccounted for (4%). Three groups were studied: 1) never obtained benzodiazepine prescription (NOB): n=80); 2) briefly/occasionally prescribed benzodiazepines (BOP): n=71; 3) BMT: n=127. OUTCOMES MEASURED Treatment retention (months); deaths/100 patient treatment years; deaths after leaving the service/100 years of information. RESULTS Treatment retention: NOB: 34 months; BOP: 51 months; BMT: 72 months. In-treatment mortality: NOB: 1.79/100 patient treatment years; BOP: 0.33/100 patient treatment years; BMT: 1.31/100 patient treatment years. Deaths after leaving service: NOB: 2.24/100 years of information, BOP: 0.63/100 years of information. However, mortality for previously BMT-patients increased by 450% to 5.90/100 years of information. DISCUSSION BMT patients had longer treatment retention than NOB or BOP and lower mortality than NOB patients. It is unlikely that patients had access to prescribed benzodiazepines on leaving the service because of restrictions in the national guidelines but co-dependent patients are a high-risk group who may stand to gain most benefit from opiate substitution treatment if combined with benzodiazepine-maintenance.

Abstract
OBJECTIVE There is a significant interindividual variability in treatment outcomes in methadone maintenance treatment (MMT) for opioid use disorder (OUD). This prospective cohort study examines the impact of comorbid psychiatric disorders on continued illicit opioid use in patients receiving MMT for OUD. METHODS Data were collected from 935 patients receiving MMT in outpatient clinics between June 2011 and June 2015. Using linear regression analysis, we evaluated the impact of having a comorbid psychiatric disorder on continued illicit opioid use during MMT, adjusting for important confounders. The main outcome measure was percentage of opioid-positive urine screens for 6 months. We conducted a subgroup analysis to determine the influence of specific comorbid psychiatric disorders, including substance use disorders, on continued illicit opioid use. RESULTS Approximately 80% of participants had at least one comorbid psychiatric disorder in addition to OUD, and 42% of participants had a comorbid substance use disorder. There was no significant association between having a psychiatric comorbidity and continuing opioid use (P=0.248). Results from subgroup analysis, however, suggest that comorbid tranquilizer (β=20.781, P<0.001) and cocaine (β=6.344, P=0.031) use disorders are associated with increased rates of continuing opioid use. CONCLUSION Results from our study may serve to guide future MMT guidelines. Specifically, we find that cocaine or tranquilizer use disorder, comorbid with OUD, places patients at high risk for poor MMT outcomes. Treatment centers may choose to gear more intensive therapy toward such populations.

Abstract
BACKGROUND Best practice models are calling for a holistic, needs-led, and sex-informed treatment approach to substance misuse treatment. To date, research into the impact of sex on needs and quality of life within methadone-treatment populations using validated research tools is limited. OBJECTIVES The aim of the study was to evaluate the impact of sex upon self-rated unmet need and quality of life among people on methadone treatment. METHODS Cross-sectional survey of adults attending a specialist methadone treatment clinic, in Dublin, Ireland. Participants completed the Camberwell Assessment of Need Short Appraisal Schedule, Patient Version and the WHO Quality of Life-Brief Version. Ongoing drug use was determined using the Maudsley Addiction Profile and weekly supervised urine toxicology screens. A linear regression analysis was conducted. RESULTS One hundred eight of 190 eligible service-users (57%) participated. No significant differences existed between the participants and the nonparticipants on demographic variables or measures of drug use. Among them, 33% were women. Women demonstrated lower levels of ongoing opiate use. Linear regression analysis indicated that women had a greater number of unmet needs (P = 0.02) and lower quality of life in the domains of physical health (P = 0.003), psychological well being (P < 0.001), environmental well being (P = 0.03), and social relationships (P = 0.007). When the Bonferroni adjustment was applied to account for multiple testing, the relationship between psychological well being and female sex remained statistically significant. CONCLUSIONS Our study suggests that female sex may be associated with greater self-rated needs and poorer quality of life within a methadone-treated population, in particular, in the domain of psychological well being. Further research in this area is warranted to discover if these findings can be replicated and confirmed in larger samples.

Same-day use of opioids and other central nervous system depressants amongst people who tamper with pharmaceutical opioids: A retrospective 7-day diary study. Drug Alcohol Depend 2016; 166:125-33. [PMID: 27430400 DOI: 10.1016/j.drugalcdep.2016.07.003] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2016] [Revised: 06/27/2016] [Accepted: 07/03/2016] [Indexed: 11/25/2022]
Abstract
OBJECTIVE The aims were to determine: (i) quantity and frequency of same-day use of opioids with benzodiazepines and/or alcohol amongst people who regularly tamper with pharmaceutical opioids; and (ii) socio-demographic, mental health, harms and treatment profile associated with same-day use of high doses. METHOD The cohort (n=437) completed a retrospective 7-day diary detailing opioid, benzodiazepine, and alcohol intake. Oral morphine equivalent (OME) units and diazepam equivalent units (DEU) were calculated, with >200mg OME, >40mg DEU and >4 standard alcoholic drinks (each 10g alcohol) considered a "high dose". RESULTS One-half (47%) exclusively consumed opioids without benzodiazepines/alcohol; 26% had days of opioid use with and without benzodiazepines/alcohol; and 26% always used opioids and benzodiazepines/alcohol. Same-day use of opioids with benzodiazepines/alcohol typically occurred on 1-3days in the past week. Six in ten (61%) participants reported high dose opioid use on at least one day; one in five (20%) reported high dose opioid and high dose benzodiazepine/alcohol use on at least one day. The latter group were more likely to use prescribed opioid substitution therapy, often alongside diverted pharmaceutical opioids. Socio-demographic and clinical profiles did not vary according to high dose opioid, alcohol and benzodiazepine use, and there was no association with harms. CONCLUSIONS Same-day use of opioids with benzodiazepines/alcohol, and high dose combinations, are common amongst people who tamper with pharmaceutical opioids. Assessment of concomitant benzodiazepine/alcohol use during opioid therapy, implementation of real-time prescription monitoring systems, and research to clarify upper safe limits for polydrug depressant use, are potential implications.

[PMID: 27431047 DOI: 10.1016/j.jsat.2016.06.008] [Citation(s) in RCA: 42] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2016] [Revised: 05/06/2016] [Accepted: 06/06/2016] [Indexed: 10/21/2022]
Abstract
BACKGROUND Over the past decade, patients admitted to addiction treatment programs have reported increasing rates of concurrent opioid and benzodiazepine (BZD) use. This drug combination places individuals at high risk for accidental overdose. Little is known about reasons for BZD use among individuals seeking treatment for opioid use disorders. METHODS We surveyed consecutive persons initiating inpatient opioid detoxification and identified 176 out of 438 who reported BZD use in the past 30 days and/or had a positive toxicology. RESULTS Forty percent of persons surveyed used a BZD in the month prior to admission, and 25% of these met criteria for BZD dependence (DSM IV). BZD users averaged 32.0 years of age, 63.6% were male, 85.2% used heroin, and reported, on average, 13.3 (±11.2) days of BZD use during the past month. Alprazolam (Xanax) was the most commonly used BZD (52%), and buying it on the street the most common source (48%). The most commonly reported reason for BZD use was 'to manage anxiety' (42.6%), followed by 'to get or enhance a high' (27.7%), 'to help with sleep' (11.4%), and 'to decrease opioid withdrawal' (10.2%). The most common reason for BZD use was significantly associated (p<.001) with most likely source of BZDs, with persons who got their BZDs from a prescriber (23%) more likely to report BZD anxiety as their primary reason for use, while persons who bought BZDs on "the street" (48%) had the highest likelihood of reporting using BZD to get or enhance a high. Participants using BZDs most commonly for anxiety did not endorse lower anxiety than those using BZDs for other reasons. CONCLUSIONS Two in five persons seeking detoxification for an opioid use disorder used a BZD in the prior month. Anxiety was the most common reason patients reported using a benzodiazepine, but they also reported using BZDs to enhance a 'high' and manage opioid withdrawal. Evidence-based discussions about the risks of combining BZDs and opioids, and alternatives to BZDs should be a high priority in detoxification settings.

Abstract
BACKGROUND Benzodiazepines are frequently prescribed to patients with drug use disorders. However, it has previously been difficult to distinguish whether this frequent prescribing was due to underlying psychiatric disorders or inappropriate prescribing. In a nationwide cohort study, we investigated the prescribing of benzodiazepines to patients with drug use disorders in connection with treatment admission. METHODS Benzodiazepine prescriptions to patients (N = 33203) aged 18 to 67 years admitting for outpatient treatment for drug use disorders in Denmark, 2000 to 2010, were studied by using linked data from nationwide health registries. Factors associated with increasing amounts of benzodiazepine use within the first year after admission were assessed by multinomial logistic regression. Proportions of very long-term benzodiazepine prescription were calculated. RESULTS During the first year after admission to treatment, 26.2 % of patients were prescribed benzodiazepines. Of these, 35.5 % were prescribed benzodiazepines at dose levels that might indicate inappropriate use (>365 Defined Daily Dose per year), and 34.6 % were prescribed more than one type of benzodiazepines. Diazepam was the most commonly prescribed type. Among patients with opioid use, 43.2 % were prescribed benzodiazepines which were three times higher than for patients with cannabis (12.2 %) or central stimulating drugs (13.8 %) as their primary drug use. Admitting to treatment for a drug use disorder did not increase the specialized psychiatric treatment coverage of this patient group, disregarding use of prescribed benzodiazepines. 29.5 % were new users of prescribed benzodiazepines, and of these, 27.5 % continued into very long-term use (≥4 years after admission) during the study period. CONCLUSIONS Benzodiazepines were commonly prescribed to patients admitting to treatment for drug use disorders, and included prescription of multiple and non-optimal types, high doses, and very long-term prescriptions. These findings point towards inappropriate prescribing of benzodiazepines in many cases more than treatment for psychiatric disorders.

Abstract
Benzodiazepine (BZD) abuse has reached epidemic levels and results in poor outcomes, particularly when combined with concomitant central nervous system depressants. BZDs are abused most commonly in combination with opioids and alcohol. Emergency department visits and related deaths have soared in recent years. In the absence of other medications or illicit substances, BZDs are rarely the sole cause of death. Prescription drug abuse has received more attention in recent years, yet much remains unknown about BZD abuse. BZDs have low abuse potential in most of the general population. A subset is at elevated risk of abuse, especially those with a history of a substance use disorder. Education, prevention, and identification are vital in reducing BZD abuse.

Abstract
BACKGROUND Benzodiazepine use has been associated with addiction-related risks, but little is known about its association with aberrant drug-related behaviors in patients receiving opioids for chronic pain. The authors examined the association between receipt of a benzodiazepine prescription and 2 aberrant drug-related behaviors, early opioid refills and illicit drug (cocaine) use in patients receiving opioids for noncancer chronic pain. METHODS This was a retrospective cohort study of 847 patients with ≥1 visit to either a hospital-based primary care clinic or one of two community health centers between September 1, 2011, and August 31, 2012. All patients received ≥3 opioid prescriptions written at least 21 days apart within 6 months, and ≥1 urine drug screen during the study period. A Cox proportional hazards model estimated the hazard of a second early opioid refill, defined as an opioid prescription written 7-25 days after the previous prescription for the same drug, as a function of time-varying benzodiazepine prescription. A logistic regression model examined the relationship between benzodiazepine prescription and a positive urine test for cocaine. Models were adjusted for demographics and mental/substance use disorder diagnoses. RESULTS Twenty-three percent (n = 196) of patients received ≥1 benzodiazepine prescription during the study period. Twenty-two percent (n = 183) of patients had ≥2 early opioid refills, and 11% (n = 93) had ≥1 positive urine drug tests for cocaine. Receipt of benzodiazepine prescription was associated with an increased hazard of having a second early opioid refill, adjusted hazard ratio = 1.54 (95% confidence interval [CI]: 1.09-2.18), but not associated with a positive cocaine test, adjusted odds ratio = 1.07 (95% CI: 0.55-2.23). CONCLUSIONS Among primary care patients receiving chronic opioid therapy, benzodiazepine prescription was associated with early opioid refills but not with cocaine use. Further research should better elucidate the risks and benefits of prescribing benzodiazepines to patients receiving opioids for chronic pain.

Abstract
OBJECTIVES To examine the relationship between benzodiazepine (BZD) use and HCV seroconversion in 2 linked prospective cohorts of persons who inject drugs (PWID). METHODS We examined prospective cohorts of 440 PWID (baseline BZD users: n = 102; 23.2%) from the AIDS Care Cohort to Evaluate Access to Survival Services (ACCESS) and the Vancouver Injection Drug Users Study (VIDUS) cohorts, followed-up from 1996 to 2013 in Vancouver, Canada. RESULTS At baseline, the prevalence of HCV was higher among those who used BZD (80.5% vs 61.5%; P < .001). After adjustment, BZD use remained independently associated with increased rates of HCV seroconversion (adjusted rate ratio = 1.67; 95% confidence interval = 1.05, 2.66). CONCLUSIONS BZD use is independently associated with HCV seroconversion in a population of PWID.
