Considerable resources have been spent on estimating the size of populations of people who use drugs (PWUD) and people who inject drugs (PWID) in Africa. Precise estimates are elusive, not least because of stigma and criminalization faced by these populations. Bio-behavioral surveys focused on...

Substance use has been identified as a notable phenomenon in reception settings in EU Member States and the Schengen associated countries. The EUAA is thus putting prevention in focus when working with applicants and particularly so with boy applicants who are the group identified as most at...

Sharing used injection equipment is one of the main ways in which drug users run the risk of infection (e.g., with HIV, or hepatitis B and C). This has led to the introduction of harm reduction (HR) strategies, such as needle exchange programmes (NEPs). Injection use is considered to be less...

This page provides an overview of key issues related to the provision of harm reduction equipment for high-risk drug use, including service delivery, guidance and evidence, and considerations for implementation. It also considers implications for policy and practice.

Patients in rural areas have higher rates of opioid use and overdose than those in urban areas that are linked to the greater prevalence and amounts of opioids prescribed. We merge individual claims data with county-level supply and demand factors to examine this relationship between...

Efficient and interconnected logistics networks, like postal services, provide powerful tools for criminal groups to organize cross-border drug trafficking by exploiting legitimate infrastructure. Despite postal services becoming inadvertent facilitators in smuggling, focused research on this...

Using a sample of Australians who display high rates of early school-leaving, we compare the trajectories of respondents who left school at each incremental age between 14 and 17 with respondents who left at 18 years old or more, in terms of homelessness, incarceration, substance use and mental...

Using a sample of disadvantaged Australians, we compare trajectories of those who left school before 18 with those who left later, in terms of homelessness, incarceration, substance use and mental health issues. We estimate a staggered difference-in-difference to account for heterogenous...

Around 50 years ago, the Netherlands decriminalized cannabis for recreational use. This paper uses retrospective data on the ages at which individuals began and ceased cannabis use to reconstruct its prevalence in Amsterdam during the period surrounding the policy change. This approach enables a...

Cannabis regulatory reform has opened areas for product innovation and entrepreneurship. One dimension that has so far been understudied is the potential for cannabidiol (CBD) and tetrahydrocannabinol (THC) beverages. This study uses double-bounded contingent valuation techniques and parametric...

The illicit drug trade generates billions of dollars and sustains transnational criminal organisations. Drug markets can destabilise governance and undermine development. Data indicate increasing drug use in South Africa. However, information on the size and value of the drug market is limited....

This article reassesses the book Africa and the War on Drugs (2012) and a related special journal issue (2016) in the light of drug market and policy developments since 2012. As part of this reassessment, we question some of the assumptions made in the book and special issue. More specifically,...

The production, distribution, and consumption of drugs has long been seen as a threat to social and economic development. On the other hand, conditions of unemployment and poverty foster expansion of illegal drug markets. In this study, I offer a nuanced view of the drugs/development connection...
