Ten-year longitudinal study of incarceration among a community-based cohort of people who inject drugs
People who inject drugs are over-represented among incarcerated populations. However, there are few studies elucidating patterns of incarceration among people who inject drugs, especially among community-based cohorts. Furthermore, data on drug use and injecting risk behaviours in carceral settings are limited globally. We aimed to describe lifetime patterns of incarceration, as well as drug use and injecting risk behaviours while incarcerated, a…

Factors Associated With Opioid Agonist Treatment Engagement and Harm Reduction Service Use
Can real-world scaling up HCV treatment in people who inject drugs be cost-saving
INTRODUCTION: UK is one of a few countries that are likely to meet WHO HCV elimination targets of reducing incidence to <2 per 100 person years in People Who Inject Drugs (PWID), but the economic case may be important for investment elsewhere and in future in UK. We illustrate the impact of real-world scaled-up HCV treatment to assess under what drug treatment costs could the investment be cost-saving. METHODS: We utilised a mathematical and econ…
Drug-related death rates associated with prescribed and illicit benzodiazepine exposure among people receiving opioid-agonist treatment in Scotland, 2015 to 2020
BACKGROUND: Opioid agonist treatment (OAT) reduces mortality among individuals with opioid dependence. Benzodiazepine co-prescribing with OAT has previously been associated with increased rates of drug-related death (DRD). In Scotland, rising DRD rates have coincided with increasing detection of illicit benzodiazepines at post-mortem. We quantified DRD rates associated with prescribed and baseline self-reported illicit benzodiazepine exposure amo…
Universal Barriers and Facilitators to Systemic Hepatitis C Care
Scaling up hepatitis C virus (HCV) testing and treatment for people who inject drugs (PWID) is essential to achieve HCV elimination. We report a retrospective systems‐informed qualitative process evaluation of HCV care across multiple community‐based settings in a region in Scotland, UK. Using secondary data from 71 semi‐structured interviews with HCV service providers ( n = 40) and service users ( n = 31) from across the whole system, we identif…

Initiation, cessation and resumption of attendance at the Melbourne supervised injecting room among a cohort of people who inject drugs
We found high MSIR service uptake, relative to cessation. Attendance was higher among men, Aboriginal and/or Torres Strait Islander people, and those recently homeless, with frequent attenders injecting more often and those on OAT less likely to attend frequently
Dynamic shifts in crystal methamphetamine and heroin price and purity in metropolitan Melbourne and rural Victoria, Australia, 2009-2020
Overall declines in both crystal methamphetamine and heroin purity-adjusted prices in Victoria suggests that, by 2019, people who purchased these drugs received more drug for a given purchase than in previous years. These changes closely match trends seen in some key harms such as opioid overdose
Optimal provision of opioid agonist therapy (OAT) and needle and syringe programmes (NSP)
These findings show how interacting relational and structural mechanisms generate optimal outcomes, guiding policy and service design. Implementing a multi-agency approach, integrating different mechanisms across the identified contexts, may be necessary to achieve optimal service delivery

Characterising benzodiazepine use and the association with non-fatal overdose among people who inject opioids in England, Wales and Northern Ireland
Benzodiazepine use is common among PWIO in England, Wales, and Northern Ireland, and is associated with higher prevalence of non-fatal overdose. These findings underscore the need to strengthen overdose prevention and harm reduction efforts addressing benzodiazepine use across the UK
Has the HCV cascade of care changed among people who inject drugs in England since the introduction of direct-acting antivirals
COC stages from seeing a specialist onwards improved after DAAs became widely available. Further improvements in HCV testing are needed to eliminate HCV in England
Using modelling and public health surveillance data to evidence progress towards the WHO incidence target for hepatitis C elimination in people who inject drugs - a review of complementary approaches …
Risk of drug-related mortality among people receiving opioid-agonist treatment during the Covid-19 pandemic in Scotland
During the COVID-19 pandemic in Scotland, DRD rates remained stable following a three-fold rise since 2011-13. The protective effect of OAT was sustained during the pandemic, which highlights the importance of maintaining access to OAT during public health crises
Evaluating the effect of direct-acting antiviral agent treatment scale-up on Hepatitis C virus prevalence among people who inject drugs in UK
Real-world evidence showing substantial reductions in chronic HCV associated with increase of HCV treatment scale-up in the community thus supporting the effectiveness of HCV treatment as prevention in people who inject drugs
Childhood conduct problems, potential snares in adolescence, and problematic substance use in Brazil
Childhood conduct problems are associated with problematic substance use in adulthood; however, little is known about what might explain these associations outside of high-income countries where the majority of research is conducted. Data were analyzed from 4599 young people from the 1993 Pelotas Birth Cohort in Brazil. The exposure was conduct problems (age 11 years). Outcomes included hazardous alcohol consumption and illicit drug use (age 22 y…

Engagement in rapid public health research among young people from underserved communities
This research explored barriers to engagement in rapid public health co-production. Working with communities to co-produce rapid recruitment and research procedures to suit the needs and the context in which young people live is necessary
Making sense of drug use and dependence—A scoping review of mass media interventions intended to reduce stigma towards people who use drugs
We found inconsistencies in approaches to reduce and measure stigma, potentially reflecting different motivations for intervention development. The primary motivation of many interventions was seemingly to promote drug service engagement and recovery
Patterns of drug use among people who inject drugs
The role of emotion in urban development decision-making
People's feelings about their neighbourhoods are important for health, but they may be undervalued in urban development decision-making. This study explores how decision-makers understand and respond to residents' emotions. Reflexive thematic analysis was conducted on a secondary dataset consisting of 123 interviews with influential professionals in urban development decision-making. We developed three themes and one subtheme: '(mis)understanding…
Does Self‐control Affect Survey Response? Applying Exploratory, Confirmatory, and Item Response Theory Analysis to Grasmick Et Al.'s Self‐control Scale
Gottfredson and Hirschi's (1990) A General Theory of Crime has sparked a great deal of theoretical debate and empirical investigation. Tests of the theory have focused on measuring the core element, the latent trait of self‐control. The majority of this research has used the 24‐item scale developed by Grasmick et al. (1993), and a great deal of attention has been directed at the validity of this scale. Empirical debate revolves around the unidime…
The Validity of a Self-reported Delinquency Scale
Self-reported delinquency scales have been widely adopted by researchers seeking to measure delinquency. Establishing the validity of these scales is critical because if valid measures are not created, findings about the correlates of delinquency will be of limited use in testing theory and formulating public policy. In this article, the authors use data from the first wave of the National Youth Survey to examine the measurement properties of a c…
Methods to Recruit Hard-to-Reach Groups
Evidence suggests rapid diffusion of injecting drug use and associated outbreaks of HIV among injecting drug users (IDUs) in the Russian Federation and Eastern Europe. There remains a need for research among non-treatment and community-recruited samples of IDUs to better estimate the dynamics of HIV transmission and to improve treatment and health services access. We compare two sampling methodologies "respondent-driven sampling" (RDS) and chain …
An Empirical Test of Tittle's Control Balance Theory
Classic statements of control theory propose that individuals who are controlled or bonded will be more likely to be deterred from deviance, while those who are not controlled or bonded will be more likely to turn to deviance. In a recent restatement of control theory, Tittle (1995) offers an alternative viewpoint. Though he agrees that a lack of control (a control deficit) can lead to repressive forms of deviance (predation, defiance, and submis…
Among friends
Drinking is viewed by young people as a predominantly social activity which provides an opportunity for entertainment and bonding with friends. Using Bourdieu's concepts of habitus, field and capital, this article explores young people's attitudes and beliefs around alcohol use, influences on behaviour, and the role of peers, with a view to informing the development of preventive interventions. Semi-structured interviews were conducted with 28 yo…

Patterns of cannabis use during adolescence and their association with harmful substance use behaviour
BACKGROUND: Evidence on the role of cannabis as a gateway drug is inconsistent. We characterise patterns of cannabis use among UK teenagers aged 13-18 years, and assess their influence on problematic substance use at age 21 years. METHODS: We used longitudinal latent class analysis to derive trajectories of cannabis use from self-report measures in a UK birth cohort. We investigated (1) factors associated with latent class membership and (2) whet…
Testing the impact of local alcohol licencing policies on reported crime rates in England
BACKGROUND: Excessive alcohol use contributes to public nuisance, antisocial behaviour, and domestic, interpersonal and sexual violence. We test whether licencing policies aimed at restricting its spatial and/or temporal availability, including cumulative impact zones, are associated with reductions in alcohol-related crime. METHODS: Reported crimes at English lower tier local authority (LTLA) level were used to calculate the rates of reported cr…
Local policies to tackle a national problem
Measurable effects of local alcohol licensing policies on population health in England
BACKGROUND: English alcohol policy is implemented at local government level, leading to variations in how it is put into practice. We evaluated whether differences in the presence or absence of cumulative impact zones and the 'intensity' of licensing enforcement--both aimed at regulating the availability of alcohol and modifying the drinking environment--were associated with harm as measured by alcohol-related hospital admissions. METHODS: Premis…
The Developmental Relationship Between Depressive Symptoms in Adolescence and Harmful Drinking in Emerging Adulthood
The intervention effect of local alcohol licensing policies on hospital admission and crime
BACKGROUND: Control of alcohol licensing at local government level is a key component of alcohol policy in England. There is, however, only weak evidence of any public health improvement. We used a novel natural experiment design to estimate the impact of new local alcohol licensing policies on hospital admissions and crime. METHODS: We used Home Office licensing data (2007-2012) to identify (1) interventions: local areas where both a cumulative …
Alcohol consumption and internalising disorders in young adults of ALSPAC
Introduction Depression and harmful alcohol consumption contribute significantly to the global health burden, but in young adults, this relationship is under-researched and conflicted. The aim of this study was to determine the sex-based prevalence and the association between internalising disorders such as depression and alcohol use disorders. Method Using the Avon Longitudinal Study of Parents and Children, we assessed the sex-specific prevalen…
Injecting drug use in Brighton, Liverpool, and London
Study objective: To estimate the prevalence of injecting drug use (IDU) in three cities in England and to measure the coverage of key public health indicators. Design: Capture-recapture techniques with covariate effects. Setting: Liverpool, Brighton, and 12 London boroughs, 2000/01. Participants: IDU collated and matched across five data sources—community recruited survey, specialist drug treatment, arrest referral, syringe exchange, and accident…

Costs and Characteristics of Heavy Inpatient Service Users in Outer London
"Heavy users" is a new term often used to describe those who occupy a disproportionate number of psychiatric beds. In this study we identified the heaviest 10% (193) inpatient service users in one London borough over a 61/2 year period and compared these with a control group of 400 ordinary inpatient users. A weighting index was used to combine frequency of admission with duration. Heavy users were diagnostically and demographically similar to or…

Drug-Related Mortality and Fatal Overdose Risk
Research Briefing
This article discusses approaches to assessing the size of the illicit market for powder cocaine, and the inherent difficulties of this issue. It describes recent attempts to investigate more accurate measures of the prevalence and extent of use than have been available to date. A new approach is suggested in which estimates are derived separately ‐ using separate methodologies for different groups of powder cocaine users, and then summed. The re…
Global overview of injecting drug use and HIV infection among injecting drug users
OBJECTIVE: To provide global estimates of the prevalence of injecting drug use (IDU) and HIV prevalence among IDU, in particular to provide estimates for developing and transitional countries. METHODS: Collation and review of existing estimates of IDU prevalence and HIV prevalence from published and unpublished documents for the period 1998-2003. The strength of evidence for the information was assessed based on the source and type of study. RESU…

Methods for assessing HIV and HIV risk among IDUs and for evaluating interventions
Public injecting and the need for ‘safer environment interventions’ in the reduction of drug‐related harm
Background One key structural dimension in the distribution of drug‐related harm associated with injecting drug use is the injecting environment. Epidemiological evidence associates elevated blood‐borne viral risk with injecting in ‘public’ and ‘semipublic’ environments. Yet the quality of evidence on public injecting and related viral risk is variable, and is lacking in many countries such as the United Kingdom. Aim This commentary considers the…
The diffusion of heroin epidemics
Methods to Recruit Hard-to-Reach Groups
Evidence suggests rapid diffusion of injecting drug use and associated outbreaks of HIV among injecting drug users (IDUs) in the Russian Federation and Eastern Europe. There remains a need for research among non-treatment and community-recruited samples of IDUs to better estimate the dynamics of HIV transmission and to improve treatment and health services access.

Differences between injectors and non-injectors, and a high prevalence of benzodiazepines among drug related deaths in Scotland 2003
Drug related deaths (DRDs) have been increasing in Scotland over at least the past decade. This study aimed to describe the characteristics (gender, age, ICD10 cause of death), toxicology and circumstances of all Scotland's DRDs in 2003 to help inform a national overdose prevention strategy. Coronial files for 300/317 (95%) DRDs registered with the General Register Office for Scotland (GROS) in 2003 were examined retrospectively (in 2004). Charac…
Validating estimates of problematic drug use in England
This is the first UK study to determine the validity estimates of problematic and injecting drug misuse. The results of this paper highlight the need to consider criterion and face validity when evaluating estimates of the number of drug users
Global epidemiology of injecting drug use and HIV among people who inject drugs
Early adolescent substance use and parental socio economic position earlier in life
To examine the association between different indicators of parental socio-economic position (SEP) and a range of substance use in their adolescent offspring. Longitudinal observational study. Population based birth-cohort from the early 90s in the Avon region (ALSPAC, UK). The sample consists of 5837 children (2877 boys and 2960 girls), who attended a face-to-face interview when they were aged 13 (80.5%) or 14. Alcohol consumption without parenta…
The Edinburgh Addiction Cohort
Objective: The misuse of substances (alcohol and illicit drugs) during pregnancy is increasingly common in the UK and is associated with poor maternal and foetal outcomes. Current estimates are that 2-3% of children have a substance misusing parent. There is a poor understanding of the demographics of pregnant substance misusers, of the patterns of antenatal service provision and little evidence about which service model is most effective at opti…
HIV prevention, treatment, and care services for people who inject drugs
Prevention of HIV infection for people who inject drugs
The Edinburgh Addiction Cohort
Injecting drug users recruited from a community setting can be successfully followed-up through interviews and record linkage. Information from injecting cases is being analysed in terms of injecting patterns and possible influences on these. Comparisons between cases and controls will allow identification of possibly modifiable early life risk factors for drug injection and will also clarify the burden of disease associated with injection and th…
Hepatitis C virus treatment for prevention among people who inject drugs
UNLABELLED: Substantial reductions in hepatitis C virus (HCV) prevalence among people who inject drugs (PWID) cannot be achieved by harm reduction interventions such as needle exchange and opiate substitution therapy (OST) alone. Current HCV treatment is arduous and uptake is low, but new highly effective and tolerable interferon-free direct-acting antiviral (DAA) treatments could facilitate increased uptake. We projected the potential impact of …

OP29 Examining Inequalities in the uptake of the School-Based HPV Vaccination Programme in England
Background Since 2008, in the United Kingdom the HPV vaccine has been made routinely available to young women aged 12 to 13 years. A course of three doses of the vaccine offered protection against HPV 16 and 18, responsible for approximately 70% of cases of cervical cancer. Although uptake of the HPV vaccine is high, it is unknown whether the vaccine is being delivered equitably by ethnicity or deprivation. This study aimed to investigate factors…
