Main problems experienced by the neighbors of open drug scenes, Tehran, Iran: a mixed-method study.

BACKGROUND: Despite law enforcement and health interventions, open drug scenes have led to problems in many countries. The problems are, however, insufficiently explored. There are different types of drug scenes in Iran. This study aimed to explore the issues related to neighbors of one of the drug scenes in Tehran known as Farahzad. METHODS: Data were generated via semi-structured interviews in the first step of the current mixed-method study (2020-2021). Interviewees were people who use drugs (PWUDs), residents and business owners (N = 25). In the next step, a quantitative observation was conducted for eight days. The results were analyzed using conventional content analysis and descriptive statistics. RESULTS: The perceived problems were ambivalent attitudes about drug scene-related activities, violate of the territory of the self of the effected residents, and everyday concerns. The observation results indicated that men who use drugs are involved in drug scene-related activities more than women are. PWUDs try to hide their activities from the public view. Their efforts were considered "self-regulatory strategies" in the drug scene. CONCLUSIONS: Despite efforts of PWUDs to keep their activities invisible, drug scene-related issues are intolerable for neighbors. Neighbors and PWUDs have ambivalent attitudes. While they are concerned about the human rights of each other, drug scene-related activities have disturbed the neighbor's daily life and economic activities. Although law enforcement and harm reduction interventions reduce some of the problems, one of the approaches should be improving the coexistence between the neighbors and the residents of the drug scene to achieve broader and more sustainable compromises.

Mortality, Causes of Death, and Predictors of Death among Patients On and Off Opioid Agonist Treatment: Results from a 19-Year Cohort Study.

BACKGROUND: Mortality is increased among people with opioid use disorder but reduced while on opioid agonist treatment (OAT). However, the impact of patient and treatment characteristics on mortality and causes of death is insufficiently studied. OBJECTIVES: The objective of this study was to explore mortality and causes of death and examine the impact of patient and treatment characteristics on mortality in an OAT cohort with high retention in treatment. METHODS: Design: longitudinal cohort study. SETTING: Norway. Observation period: time from OAT start as of 1998 until death or end of 2016, 2,508 person-years (PY) in total. SAMPLE: 200 persons starting OAT 1998-2007. DATA SOURCES: hospital records, interviews, the Norwegian Cause of Death Registry, Statistics Norway. RESULTS: Retention: 86.4% of the observation period was on OAT, 9.0% off, 4.6% unknown OAT status. All-cause crude mortality rate per 100 PY during the whole observation period was 1.64 (95% CI: 1.19-2.20), for deaths of somatic cause 0.88 (0.56-1.31), for drug-induced deaths 0.44 (0.23-0.76), and traumatic deaths 0.24 (0.10-0.50). Off-versus-on-OAT all-cause mortality ratio was 2.31 (1.00-4.85). On OAT, 58% of the deaths were of somatic cause and 21% drug-induced; off OAT, 38% of somatic cause and 50% drug-induced. Increasing baseline age and rate of somatic hospital treatment episodes were independently associated with increased all-cause mortality risk, while increasing rate of in-patient psychiatric treatment episodes was associated with reduced risk. Increasing duration of nicotine and cannabis use and alcohol dependence as well as increasing severity of polydrug use were associated with increased all-cause and somatic mortality adjusted for age and sex. CONCLUSION: The long observation period made it possible to demonstrate the importance of long-term retention in OAT to reduce mortality. Further, the preponderance of somatic and reduction of drug-induced causes of death during OAT underlines the need for follow-up of chronic diseases and health-promoting lifestyle changes. These findings add to the knowledge about long-term OAT effects, not least in ageing OAT populations.

Indicators of Drug-Related Community Impacts of Open Drug Scenes: A Scoping Review.

INTRODUCTION: Places where people deal and/or use drugs publicly are known as open drug scenes (ODSs). Drug-related community impacts (DRCIs) refer to drug-related issues that negatively influence public and individual health, communities, businesses, and recreational and public space enjoyment. There are no well-established criteria for identification of DRCIs. We therefore performed a scoping review of literature to determine DRCIs indicators associated with ODSs. METHODS: The review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for scoping reviews (PRISMA-ScP). We searched English articles in PubMed, Scopus, Web of Science, and EMBASE databases from 1990 to 2021. The keywords were drug-related crime, drug-related offense, misconduct, social marginalization, homeless drug users, open drug scene, drug-related street disorder, public nuisance, and community impact. RESULTS: Sixty-four studies were identified. Twenty-five studies were included. Two studies (8%) were about drug-related public nuisance, 1 (4%) considered drug-related social problems, 2 (8%) focused on drug-related social disorder, and 18 studies (72%) discussed indicators of community impacts such as crime, drug-related litter, safety, noise, and drug use in public. Two studies (8%) included the frequency of drug use in ODSs. DISCUSSION: DRCI indicators are heterogenic, and various factors affect the indicators. The factors include social mores, political discourse, and historical approaches to dealing with and using drugs. Some societies do not tolerate the existence of ODSs. In contrast, many countries have adopted harm reduction programs to manage DRCIs. Identified DRCI indicators were drug using and dealing in public, drug-related litter, crime, drug-related loitering, street-based income generation activities, noise, and unsafety feelings in inhabitants. To solve the problems associated with DRCIs and to make a major change in ODSs, it is necessary to pay attention to the improvement of the economic conditions (e.g., employment opportunities), amendment (e.g., determine the limits of criminalization in drug use), and adoption of social policies (e.g., providing low-threshold and supportive services for homeless drug users).

Mortality and causes of death among patients with opioid use disorder receiving opioid agonist treatment: a national register study.

BACKGROUND: Mortality rates and causes of death among individuals in opioid agonist treatment (OAT) vary according to several factors such as geographical region, age, gender, subpopulations, drug culture and OAT status. Patients in OAT are ageing due to effective OAT as well as demographic changes, which has implications for morbidity and mortality. Norway has one of the oldest OAT populations in Europe. Because of the varying mortality rates and causes of death in different subgroups and countries, research gaps still exist. The aims of this study were to describe the causes of death among OAT patients in Norway, to estimate all-cause and cause-specific crude mortality rates (CMRs) during OAT and to explore characteristics associated with drug-induced cause of death compared with other causes of death during OAT. METHODS: This was a national, observational register study. Data from the Norwegian Cause of Death Registry and the Norwegian Patient Registry were combined with data from medical records. We included all patients in the Norwegian OAT programme who died not more than 5 days after the last intake of OAT medication, between 1 January 2014 and 31 December 2015. RESULTS: In the 2-year observation period, 200 (1.4%) of the OAT patients died. A forensic or medical autopsy was performed in 63% of the cases. The mean age at the time of death was 48.9 years (standard deviation 8.4), and 74% were men. Somatic disease was the most common cause of death (45%), followed by drug-induced death (42%), and violent death (12%). In general, CMRs increased with age, and they were higher in men and in patients taking methadone compared with buprenorphine. Increasing somatic comorbidity, measured by the Charlson comorbidity index, reduced the odds of dying of a drug-induced cause of death compared with other causes of death. CONCLUSIONS: Both somatic and drug-induced causes of death were common during OAT. Improved treatment and follow-up of chronic diseases, especially in patients aged > 40 years, and continuous measures to reduce drug-induced deaths appear to be essential to reduce future morbidity and mortality burdens in this population.

The LASSO Program in Oslo: Harm Reduction Using Buprenorphine-Naloxone (Suboxone®) in a Low Threshold Setting.

BACKGROUND: This is a 6-year retrospective quality control study of the LASSO Program (Low Threshold Substitution Treatment in Oslo), using exclusively Suboxone® (buprenorphine-naloxone [BPNX]) in out-patient settings. Adequate abstinence prior to induction is necessary to avoid acute onset opioid withdrawal symptoms; thus, its use in low threshold settings is far less common than methadone. OBJECTIVES: The aim of this study was to determine if BPNX is a safe and feasible medication to use in a low threshold setting. METHODS: The analysis is based on daily supervised BPNX medication. The standardized induction regime started with 4-mg BPNX increasing by 4 mg daily until 16 mg, with individual adjustments based on clinical status. Treatment effect was evaluated by the number of medication induction attempts, treatment length and lag time between initial contact and medication start. Statistical computations were performed with SPSS®. RESULTS: There were 331 out of 394 registered patient inquires that started on BPNX. Two hundred fifty-three patients (76.4%) completed induction on first attempt with 95% Wilson score CIs of (0.716-0.807). The accumulated percentage increased to 85.2% during successive inductions. No significant association was found between lag time and (i) the number of days on medication during the first induction; or (ii) total treatment length. Patients had a median lag time of 5 days, remained in treatment a median of 52.0 days with an average of 3.9 inductions. There were no cases of severe precipitated withdrawal and only 2 cases of adverse reactions among the 1,293 inductions and 25,544 administered dosages. CONCLUSION: This study shows that BPNX is highly effective in treating marginalized heroin addicts in low threshold settings. Even during their first attempt, 76.4% completed induction. There were no cases of severe precipitated withdrawal. Prolonged lag time affected neither the length of first treatment nor the total treatment length. Individualized induction readiness approach and motivation were central to the above results.

Tapering from Methadone or Buprenorphine during Pregnancy: Maternal and Neonatal Outcomes in Norway 1996-2009.

BACKGROUND: The tapering of methadone or buprenorphine during pregnancy is an understudied and controversial issue. The aim of this study was to determine to what extent women tapered their opioid medication dose during pregnancy and what the neonatal outcomes were for those who tapered compared to the women who did not. METHODS: The study was a mixed prospective/retrospective national cohort study of 123 Norwegian women in opioid maintenance treatment (OMT) during pregnancy and their neonates. A standardized questionnaire was administered to the women and medical information that could be used for verification was collected from hospitals and municipalities. RESULTS: Two of the women came off the OMT-medication during pregnancy and another 15% tapered their OMT-medication dose more than 50%. The birth weights of methadone-exposed neonates of the women who tapered more than 50% were significantly higher than for the methadone-exposed neonates of the women tapering between 11 and 50%. No other significant differences were found. CONCLUSION: Pregnant women in OMT who taper their OMT-medication dose should be monitored closely. We need studies that document the maternal well-being and fetal safety of maternal tapering of the OMT-medication during pregnancy.

Quetiapine abuse - myth or reality? / Kvetiapinmisbruk ­ myte eller realitet?

Quetiapine is increasingly being used as a sedative and hypnotic drug, especially in the treatment of addiction disorders. Some have warned against this practice. However, a review of the research literature lends little support to these warnings.

The effectiveness of integrated treatment in patients with substance use disorders co-occurring with anxiety and/or depression--a group randomized trial.

BACKGROUND: Integrated Treatment (IT) has proved effective in treating patients with Substance Use Disorders (SUD) co-occurring with severe Mental Disorders (MD), less is known about the effectiveness of IT for patients with SUD co-occurring with less severe MD.The aim of this study was to investigate the effectiveness of IT for patients with SUD co-occurring with anxiety and/or depression on the following parameters:1. The use of substances, as measured by the Alcohol Use Identification Test (AUDIT), the Drug Use Identification Test (DUDIT), and the Addiction Severity Index (EuropASI).2. The severity of psychiatric symptoms, as measured by the Symptom Check List 90 r (SCL 90R).3. The client's motivation for changing his/her substance use behaviour, as measured by the Substance Abuse Treatment Scale (SATSr). METHODS: This is a group randomized clinical trial comparing the effectiveness of IT to treatment as usual in Community Mental Health Centres (CMHCs). Five CMHCs were drawn to the Intervention Group (IG) and four CMHCs to the Control Group (CG). The allocation to treatment conditions was not blinded. New referrals were screened with the AUDIT and the DUDIT. Those who scored above the cut-off level of these instruments were assessed with the Structured Clinical Interview for DSM-IV 1 and 2. We included patients with anxiety and/or depression together with one or more SUDs. RESULTS: We included 55 patients in the IG and 21 in the CG. A linear multilevel model was used. Both groups reduced their alcohol and substance use during the trial, while there was no change in psychiatric symptoms in either group. However, the IG had a greater increase in motivation for substance use treatment after 12 months than had the CG with an estimate of 1.76, p = 0.043, CI95% (0.08; 3.44) (adjusted analyses). There were no adverse events. CONCLUSIONS: Integrated treatment is effective in increasing the motivation for treatment amongst patients with anxiety and/or depression together with SUD in outpatient clinics. TRIAL REGISTRATION: ClinicalTrials.gov: NCT00447733.

Open drug scenes: responses of five European cities.

BACKGROUND: Open drug scenes are gatherings of drug users who publicly consume and deal drugs. The authors conducted a study of five European cities that have met such scenes constructively. The aim was to investigate shared and non-shared interventions and strategies in order to increase the understanding of this type of problem. METHODS: First a description was made for the cities of Amsterdam, Frankfurt, Vienna, Zürich and Lisbon. These descriptions were sent to contact persons in each city prior to visit by the researchers. The methods and strategies in each city were discussed and core choices and efforts extracted. A report was sent to the contact group for corrections and clarifications. The paper analyses shared and non-shared traits and strategies. RESULTS: All of the cities had initially a period with conflict between liberal and restrictive policies. A political consensus seems to be a prerequisite for effective action. A core shared characteristic was that drug dependence was met as a health problem and drug use behaviour as a public nuisance problem. Low threshold health services including opioid maintenance treatment were combined with outreach social work and effective policing. CONCLUSION: Prevention, harm reduction and treatment should be combined with law enforcement based on cooperation between police, health care and social services. The aim should be "coexistence" between society and users of illegal substances and the strategy based on several years planning and conjoint efforts. The solutions are found in appropriate combinations of harm reduction and restrictive measures.

Making sense of differing overdose mortality: contributions to improved understanding of European patterns.

The European Monitoring Centre for Drugs and Drug Addiction, EMCDDA, publishes statistics for overdose deaths giving a European mean number, and ranking nations in a national 'league table' for overdose deaths. The interpretation of differing national levels of mortality is more problematic and more complex than is usually recognised. Different systems are used to compile mortality data and this causes problems for cross-national comparisons. Addiction behaviour can only be properly understood within its specific social and environmental ecology. Risk factors for overdose, such as the type of drug consumed, and the route of administration, are known to differ across countries. This paper describes problems associated with ranking and suggests how mortality data might be used in high-level countries aiming at reduction in the number of overdose deaths.

A day-by-day investigation of changes in criminal convictions before and after entering and leaving opioid maintenance treatment: a national cohort study.

BACKGROUND: Opioid maintenance treatment (OMT) is associated with reduced crime among heroin users, but little is known about how crime changes during different phases of treatment. The aim of this study was to investigate changes in criminal convictions on a day-to-day basis before and after entry or discharge from OMT. METHODS: National cohort study of all patients (n = 3221) in OMT in Norway 1997-2003. Patients were followed over a 9-year period, before, during, and after treatment. Criminal convictions were studied on a day-to-day basis in relation to treatment status. A time-continuous estimate of the probability of convictions within the population for all days during observation was calculated. RESULTS: Changes in convictions were evident before changes of treatment status. During the 3 years prior to OMT, the convictions rate was approximately 0.4% per day. Prior to OMT, convictions decreased to about 0.2% per day on the day of treatment initiation. During the weeks before dropping out of treatment, convictions increased. The patterns during periods of transition were the same across gender, age and pre-treatment conviction-levels. CONCLUSIONS: Changes in convictions often occurred prior to changes in treatment status. Reductions in criminal convictions were found in the period before entry (or re-entry) to OMT, and increases in criminal activity were found in the months prior to treatment interruption.

Diversity in causes and characteristics of drug-induced deaths in an urban setting.

AIMS: To assess demographic characteristics, treatment utilization and circumstances of death among those who died from drug-induced deaths in an urban setting and to identify possible subpopulations that should be targeted specifically to further develop preventive public health policies. METHODS: Subjects (N = 231) who died, from drug-induced deaths, in the Norwegian capital Oslo (2006-2008) were identified through the National Cause of Death Registry. Data on toxicology, prison release and contact with health and social services in Oslo were collected. RESULTS: Majority of cases were men (78%) and the mean age was 37 years. Nearly all cases (90%) were polydrug intoxications. Heroin was implicated in 67%. Residential address was the most common place of death (67%). Most cases (82%) had been in contact with health and social services in the year before death. Women were 4 years older, more often Oslo residents (82% vs. 64%) and fewer died from heroin intoxication. Non-Oslo residents were younger and more likely to have been found outdoors with heroin as the main intoxicant. Other identified subpopulations were those who died after prison release and those discharged from drug treatment. CONCLUSIONS: The findings suggest that the majority of cases could have been available for preventive measures through their contacts with health and social services. Yet, the heterogeneity among cases indicates that such measures need to be multifaceted. Finally, it is important for policymakers and health and social workers in various countries to consider subpopulations such as women and non-city residents when developing public health interventions to prevent overdose deaths.

Patients with nonaffective psychosis are at increased risk for heroin use disorders.

BACKGROUND/AIM: It is well-established knowledge that persons with nonaffective psychotic disorders often have problematic use of alcohol, cannabis and stimulants, but heroin use is usually not included. Our aim was to investigate the prevalence of heroin use disorders in patients with nonaffective psychosis. METHODS: As the combination of heroin use and nonaffective psychosis is infrequent, epidemiological studies have to include large populations. The present study is a case count study using information from all psychiatric and social services in Oslo. Prevalence was calculated for four possible scenarios of minimum and maximum case counts and prevalences of nonaffective psychosis. Odds ratios were calculated for the resulting prevalences compared to the minimum and maximum prevalence of heroin use disorder in the general population. RESULTS: We found between 39 and 56 subjects with nonaffective psychoses and comorbid heroin use disorder. The number of individuals with nonaffective psychosis was estimated to be between 692 and 1,730. This corresponds to a prevalence of heroin use disorder of between 2.3 and 8.1%. The odds ratio compared to the general population will range from 1.83 with a prevalence of heroin use disorder in the general population of 1.2% to 9.43 with a prevalence of 0.9%. CONCLUSION: Individuals with nonaffective psychosis are at increased risk of heroin use.
