Current data on the prevalence of prior illicit drug use among the prison population in Europe is scarce. The aim of this study is to identify the prevalence of illicit drug use prior to incarceration, as reported by studies conducted in 30 European countries. A comprehensive literature review was conducted from the 5–31 of March 2018 using the databases Cochrane Library, Embase, MEDLINE, PsychINFO and PubMed. After the deletion of duplications, 2607 articles meeting the eligibility criteria for review were identified. In total, 26 studies from 12 different countries have been included in this review. The review found that the lifetime prevalence of illicit drug use before imprisonment ranged from 30 to 93%; last year prevalence from 51 to 69%; last 6 months prevalence from 13 to 75% and last month prevalence from 58 to 62%. The prevalence of illicit drug use was especially high among women. The rates varied across the 26 studies although high prevalence values are reported in most studies and variations are partly related to methodological differences in the reviewed studies. The high levels of prior involvement with drugs, necessitates prisons to develop clear strategies to deal with illicit drug use. [ABSTRACT FROM AUTHOR]

Purpose: This paper aims to describe the impact of the COVID-19 containment measures on the provision of drug treatment and harm reduction services in European prisons in15 countries during the early phase of the pandemic (March -June 2020).Design/methodology/approach: The paper is based on a mixed method research approach that triangulates different data sources, including the results of an on-line survey, the outcome of a focus group and four national case studies.Findings: The emergence of COVID-19 led to a disruption in prison drug markets and resulted in a number of challenges for the drug services provision inside prison. Challenges for health services included the need to maintain the provision of drug-related interventions inside prison, while introducing a range of COVID-19 containment measures. To reduce contacts between people, many countries introduced measures for early release, resulted in around a 10% reduction of the prison population in Europe. Concerns were expressed around reduction of drug-related interventions, including group activities, services by external agencies, interventions in preparation for release and continuity of care.Practical Implications: Innovations aimed at improving drug service provision included telemedicine, better partnership between security and health staff and an approach to drug treatment more individualised. Future developments must be closely monitored.Originality/value: The paper provides a unique and timely overview of the main issues, challenges and initial adaptations implemented for drug services in European prisons in response to the COVID-19 pandemic.

Aims: To describe cocaine treatment demand in 10 western European countries and to examine the size, direction and temporality of recent trends in the proportion of cocaine users among all clients entering treatment. Design Aggregated data collected through the European Union standardized treatment demand monitoring system (TDI) between 2011 and 2018 were used. Setting: Belgium, England, France, Germany, Ireland, Italy, Luxembourg, Spain, Switzerland and the Netherlands. Participants: In total, more than 700 000 cocaine treatment records were analysed. Clients in treatment for cocaine as primary drug were predominantly male (85%), with an average age of 35 years. Measurements Number of treatment episodes for substance use and for cocaine as primary or secondary drug were collected year‐ and country‐wise. When available, powder cocaine and crack and patients with and without previous treatment were differentiated. Findings Among the participating countries the share of cocaine as primary drug in treatment demand ranged between 4.7% [95% confidence interval (CI) = 4.6–4.9%] in Germany and 43.1% in Spain (95% CI = 42.6–43.5%). The general trend analysis showed a decreasing proportion of cocaine‐related treatment entrants between 2011 and 2014 among all subgroups followed by a strong increase in 2015. The increase appeared stronger than for powder cocaine. Seven of 10 countries observed a recent significant increase in the proportion of treatment entrants reporting cocaine as the primary substance: Belgium [annual percentage change (APC) = 9.6%, P < 0.01], England (APC = 14.9%, P < 0.05), France (APC = 21.8%, P < 0.01), Ireland (APC = 28.2%, P < 0.01), Italy (APC = 7.8%, P < 0.01), Spain (APC = 7.0%, P < 0.05) and Switzerland (APC = 12.0%, P < 0.05). Trends were similar when looking at cocaine reported as primary or adjunctive substance. Conclusions: Despite substantial country‐specific variation regarding cocaine prevalence and treatment demand, there has been an overall significant increase since 2015 in the share of cocaine‐related treatment demand in western Europe.

This paper explores European and national trends in specialised drug treatment entry for cannabis-related problems. The analysis is based on data for the years 2003-2014 from 22 European countries. Between 2003 and 2014, the overall number and proportion of primary cannabis-related first-time entrants increased significantly. A joinpoint regression analysis indicates that the overall increase of cannabis treatment entries is continuous, although country-related differences are observed. Possible explanations for the increase and different time trends are discussed including an increase in cannabis prevalence and cannabis-related problems, changes in risk perception, increases in cannabis potency, changes in referral practices and increased availability and accessibility of treatment services.

Abstract: We estimate trends and geographical differences in the heroin epidemic in the European Union plus Croatia and Turkey by analyzing aggregated data on first heroin treatment admissions (cases) during 2000–2009. In 2005–2009 the proportion of drug injectors was higher in Central and Eastern European countries (CEECs) than in Western European countries (WECs), whereas the opposite occurred with mean age at first heroin use and first treatment. During this period, the number of cases, cases per center, and proportion of injectors in WECs declined, whereas mean age at first treatment and first heroin use increased. The opposite occurred in Turkey, except for proportion of injectors, while trends were less clear in the other CEECs. In the 7 WECs with data, trends in 2000–2005 and 2005–2009 were similar. This suggests that the number of recent-onset heroin users and heroin injectors may have declined some years before the study period, especially in WECs. [Copyright &y& Elsevier]

The aim of this article is to explore the prevalence of primary illicit stimulant use among people who enter drug treatment in Europe. Drawing on information provided by European Union treatment centres in 2009 (excluding Latvia, Lithuania, Portugal and Norway), the European Monitoring Centre for Drug and Drug Addiction showed data in relation to the analysis of two of the most problematic drugs: cocaine and stimulants other than cocaine. The analysis reached three conclusions: the primary use of stimulants (cocaine and amphetamines) among clients entering treatment appears to be widespread throughout Europe; stimulant use including different forms of stimulants varied from country to country and two geographical patterns emerge across Europe: North-Eastern European countries show high levels of prevalence of problematic use of amphetamines and methamphetamines, while South-Western countries report high levels of problematic use of cocaine.

Aims: To assesses the extent of the gender gap among the treated population of drug users across Europe. Methods: This analysis reports data on 363,170 clients from 4647 treatment units in 23 countries (22 European Union member states and Switzerland). Findings: Overall, males outnumber females by four, but the gender ratio varies not only by geographical region/country, but also by drug. In the majority of countries, the most common primary problem drug is opioids, and the overall gender ratio mirrors the gender ratio of opioid users. In some countries, a considerable proportion of treated drug users have cannabis and stimulants (cocaine/amphetamines/methamphetamines) as primary problem drugs. Stimulants other than cocaine and other drugs have lower, while cannabis has a higher than overall male-to-female gender ratio. Conclusions: The very high male-to-female gender ratios may reveal differential access to treatment. Our findings highlight the need to assess access to treatment for women problem drug users and to make women-focussed programmes more available to increase the proportion of women in drug treatment programmes across Europe.

Background: The availability of new psychoactive substances (NPS) in Europe has rapidly increased over the last decade. Although prevalence levels of NPS use remain low in the general European population, there are serious concerns associated with more problematic forms of use and harms in particular populations and settings. It has thus become a priority to formulate and implement effective public health responses. However, considerable knowledge gaps remain on current practices as well as on the challenges and needs of European health professionals who are responding to use and harms caused by these substances. The aim of this study was to explore current health responses to NPS, and highlight key issues in order to inform planning and implementation of adequate responses.Methods: This scoping study was based on a targeted multi-source data collection exercise focusing on the provision of health and drug interventions associated with NPS use and harms, in selected intervention settings across Europe.Results: Findings revealed that in the absence of specific evidence, health professionals across most intervention settings rely primarily on acquired expertise with traditional drugs when addressing NPS-related harms. This study also identified a gap in the availability and access to timely and reliable information on NPS to users and health professionals. Health professionals in sexual health settings and custodial settings in contact with certain risk groups reported particular challenges in responding to NPS-related harms.Conclusion: Immediate investments are required in expanding substance identification capabilities, competence building among professionals and dissemination of risk information among relevant stakeholders. The risks of neglecting under-served risk populations and failure to address the information needs of health professionals and users on NPS harms in a context of rapid changing drug markets in Europe may have unforeseeable consequences at societal level.

BackgroundPeople who inject drugs (PWID) are frequently incarcerated, which is associated with multiple negative health outcomes.AimWe aimed to estimate the associations between a history of incarceration and prevalence of HIV and HCV infection among PWID in Europe.MethodsAggregate data from PWID recruited in drug services (excluding prison services) or elsewhere in the community were reported by 17 of 30 countries (16 per virus) collaborating in a European drug monitoring system (2006-2020; n = 52,368 HIV+/-; n = 47,268 HCV+/-). Country-specific odds ratios (OR) and prevalence ratios (PR) were calculated from country totals of HIV and HCV antibody status and self-reported life-time incarceration history, and pooled using meta-analyses. Country-specific and overall population attributable risk (PAR) were estimated using pooled PR.ResultsUnivariable HIV OR ranged between 0.73 and 6.37 (median: 2.1; pooled OR: 1.92; 95% CI: 1.52-2.42). Pooled PR was 1.66 (95% CI 1.38-1.98), giving a PAR of 25.8% (95% CI 16.7-34.0). Univariable anti-HCV OR ranged between 1.06 and 5.04 (median: 2.70; pooled OR: 2.51; 95% CI: 2.17-2.91). Pooled PR was 1.42 (95% CI: 1.28-1.58) and PAR 16.7% (95% CI: 11.8-21.7). Subgroup analyses showed differences in the OR for HCV by geographical region, with lower estimates in southern Europe.ConclusionIn univariable analysis, a history of incarceration was associated with positive HIV and HCV serostatus among PWID in Europe. Applying the precautionary principle would suggest finding alternatives to incarceration of PWID and strengthening health and social services in prison and after release ('throughcare').

Background: People who inject drugs are often imprisoned, which is associated with increased levels of health risks including overdose and infectious diseases transmission, affecting not only people in prison but also the communities to which they return. This paper aims to give an up-to-date overview on availability, coverage and policy framework of prison-based harm reduction interventions in Europe., Methods: Available data on selected harm reduction responses in prisons were compiled from international standardised data sources and combined with a questionnaire survey among 30 National Focal Points of the European Monitoring Centre for Drugs and Drug Addiction to determine the level of availability, estimated coverage and policy framework of the interventions., Results: Information about responses to health harms in prisons is limited and heterogeneous. Cross-country comparability is hampered by diverging national data collection methods. Opioid substitution treatment (OST) is available in 29 countries, but coverage remains low (below 30% of people in need) in half of the responding countries. Needle and syringe programmes, lubricant distribution, counselling on safer injecting and tattooing/piercing are scarcely available. Testing for infectious diseases is offered but mostly upon prison entry, and uptake remains low in about half of the countries. While treatment of infections is mostly available and coverage is high for human immunodeficiency virus (HIV) and tuberculosis, hepatitis B and C treatment are less often provided. Health education as well as condom distribution is usually available, but provision remains low in nearly half of the countries. Post-release linkage to addiction care as well as to treatment of infections is available in a majority of countries, but implementation is often partial. Interventions recommended to be provided upon release, such as OST initiation, take-home naloxone and testing of infections, are rarely provided. While 21 countries address harm reduction in prison in national strategic documents, upon-release interventions appear only in 12., Conclusions: Availability and coverage of harm reduction interventions in European prisons are limited, compared to the community. There is a gap between international recommendations and 'on-paper' availability of interventions and their actual implementation. Scaling up harm reduction in prison and throughcare can achieve important individual and public-health benefits.

People in prison are disproportionately affected by viral hepatitis. To examine the current epidemiology of and responses targeting hepatitis B virus (HBV) in prisons across the European Union, European Economic Area and United Kingdom, we analysed HBV-specific data from the World Health Organization's Health in Prisons European Database and the European Centre for Disease Prevention and Control's hepatitis B prevalence database. Hepatitis B surface antigen seroprevalence ranged from 0% in a maximum-security prison in United Kingdom to 25.2% in two Bulgarian juvenile detention centres. Universal HBV screening on opt-out basis and vaccination were reported available in 31% and 85% of 25 countries, respectively. Disinfectants, condoms and lubricants were offered free of charge in all prisons in the country by 26%, 46% and 15% of 26 countries, respectively. In 38% of reporting countries, unsupervised partner visits with the possibility for sexual intercourse was available in all prisons. The findings are suggestive of high HBV prevalence amidst suboptimal coverage of interventions in prisons. A harmonised monitoring system and robust data at national and regional levels are needed to better understand the HBV situation in prisons within the framework of the European action plan and Global Health Sector Strategy on viral hepatitis.

Background: Hepatitis C virus (HCV) transmission in the European Union, European Economic Area and United Kingdom is driven by injecting drug use (IDU), which contributes to the high burden of chronic infection among people in prisons. This study aimed to describe the context, epidemiology and response targeting HCV in prisons across the region., Methods: We retrieved and collated HCV-related data from the World Health Organization's Health in Prisons European Database and the European Centre for Disease Prevention and Control's hepatitis C prevalence database. Prisons population data were obtained from the Council of Europe Annual Penal Statistics on prison populations (SPACE I)., Results: There were 12 to 93,266 people in prisons, with rates of 31·5 to 234·9 per 100,000 population. Median age was between 31 and 40 years, with up to 72% foreign nationals. Average detention time ranged from one to 31 months. Ministries of Health had sole authority over prisons health, budget administration and funding in 27, 31 and 8% of 26 reporting countries, respectively. Seroprevalence of HCV antibodies ranged from 2·3% to 82·6% while viraemic infections ranged from 5·7% to 8·2%, where reported. Up to 25·8 and 44% reported current and ever IDU, respectively. Eight countries routinely offered HCV screening on an opt-out basis. Needle and syringe programmes were available in three countries. Among the nine countries with data, the annual number of those who had completed HCV treatment ranged between one and 1215 people in prisons., Conclusions: HCV burden in prisons remains high, amidst suboptimal levels of interventions. Systematic monitoring at both local and regional levels is warranted, to advance progress towards the elimination of HCV in the region.

Objective: The article describes an epidemiological indicator called Treatment Demand Indicator (TDI). The TDI aims to provide professionals and researchers with a common European methodology for collecting and reporting core data on drug users in contact with treatment services. The article discusses the implementation of the TDI in the European countries and describes the main results, limitations, and future perspectives., Method: The TDI provides a common format for reporting data on clients entering treatment as a result of their drug use and related problems during each calendar year. Its technical protocol defines which clients should be reported at European level and represents the minimum common set of items each national monitoring system should be able to report to the European Monitoring Centre for Drugs and Drug Addiction., Results: In 2015, 29 European countries reported data on 467,811 clients entering drug treatment from 6,846 drug treatment units. Most clients were men in their 30s and had problems related to heroin or cannabis use; patterns of drug use differed geographically. Over the past decade, clients' profiles and drug use patterns changed from young heroin injectors seeking treatment to drug clients with diversified drug use patterns and profiles., Conclusions: The TDI is the largest drug dataset in Europe, and its data is increasingly used in European and national data analysis. The use of a common drug-treatment-monitoring tool across a group of countries provides a useful instrument for policymakers, professionals, and managers working in the drug treatment field.
