Civil Society Monitoring of Harm Reduction in Europe

 series explores developments in hepatitis C care for people who inject drugs, based on observations from C-EHRN focal points in 40 cities across 35 European countries. The findings point to trends such as expanded access to direct-acting antivirals (DAAs), ongoing healthcare stigma, and disparities in harm reduction funding. To gain further insights into this year’s report, we spoke with primary author Tuukka Tammi. Download the publication and read the interview below.

Compared to last year’s findings, what has changed the most in hepatitis C care for people who inject drugs?

The biggest shift is the record number of cities in the survey, giving us again a broader view of what’s happening across Europe. Forty cities across 35 European countries is a significant number. Most cities are actively encouraging treatment for people who inject drugs, and DAAs are available everywhere now, but restrictions still prevent universal access. And stigma in healthcare remains a major hurdle.

Were there any surprises in this year’s data—either positive or concerning?

A big win is that free HCV testing is now available in every city, and non-invasive diagnostics with Fibroscan® is more common. But there are still serious challenges. Harm reduction services continue to struggle with funding, and bureaucratic barriers like slow insurance approvals delay treatment.

This year’s report includes more participating cities than ever before. Did this expanded dataset bring new insights?

Definitely. The larger dataset highlights stark differences between cities making good progress and those falling behind. Some have strong policies, easy access to treatment, and well-funded harm reduction, while others still face major gaps due to restrictive policies and lack of funding. As we know more broadly, there are major divides in access to harm reduction services across Europe.

Some cities are making strong progress toward the 2030 HCV elimination goal, while others are lagging. What are the key factors that explain these differences?

Cities moving forward typically have well-funded harm reduction, fewer treatment restrictions, and national policies that prioritize HCV elimination. When treatment is accessible, and stigma is tackled, things improve. But in cities with funding cuts, excessive red tape, and discrimination in healthcare, progress stalls.

Stigma and discrimination remain a major issue in HCV care. What new insights does the 2024 report offer on this challenge?

The report makes it clear that stigma is still a huge issue, especially in general healthcare, gastroenterology clinics, and prisons. One major problem is that many healthcare providers lack training on HCV, leading to unnecessary referrals and delays in treatment. Prescription restrictions for DAAs add another layer of difficulty. If stigma isn’t tackled through policy changes and provider training, it will continue to hold back progress.

The report mentions monitoring schemes for people who inject drugs after their HCV diagnosis and treatment. How well are cities doing in this area?

It’s mixed. Just over half of the cities have structured post-treatment follow-up, which helps prevent liver damage and reinfection. But many still lack proper monitoring systems, making it easy for people to fall through the cracks.

This year’s report also examines access to hepatitis C services for people who use drugs but don’t inject. What are the key takeaways from these findings?

People who inject drugs get most of the attention, but those who use drugs in other ways are often overlooked. The report shows that access to testing and treatment for this group varies widely.

What are the top recommendations from this year’s report for policymakers and harm reduction organisations?

Mostly the same as in previous years. HCV care needs to be easier to access. Funding for harm reduction has to be protected—when services like needle exchanges and opioid agonist therapy are cut, transmission rises. Bureaucratic delays in treatment must be reduced, and healthcare providers need better training to diagnose and treat HCV without stigma. Free testing should be expanded, and governments need clear elimination strategies. Integrating harm reduction into mainstream healthcare is also key to breaking down barriers.

Based on this year’s findings, what should we be paying close attention to in 2025?

Harm reduction funding is a big concern—if cuts continue, progress could backslide. We also need to watch how policies evolve. Are they making treatment easier or harder to access?

Eliminating hepatitis C in Europe: A report on policy implementation for people who inject drugs - 2024

For almost 40 years, the Drug Consumption Rooms (DCRs) have been providing effective solutions in terms of harm reduction, human rights and public health.

Local actors, elected representatives and citizens make the opening of new DCRs worldwide possible through their commitment. Despite the many positive evaluations, the subject remains sensitive in the public debate.

This is why the City of Strasbourg, the Council of Europe's Pompidou Group and the Ithaque association are pleased to invite you to the fourth international symposium on drug consumption rooms, to be held on 18 and 19 June 2025 in the Hemicycle of the Council of Europe.

This conference continues the strong momentum started in 2019, bringing together more than 30 countries and 50 different cities at the Council of Europe in Strasbourg. Its aim is to promote the model of DCRs and to harmonize international policies around human rights and harm reduction. It offers the opportunity to share the diversity of experiences, the different legal frameworks and, their evolutions, and to put innovative practices into perspective.

Institutional actors and associations in the field, peoples who use drugs, local, national and international political leaders are all invited to attend and will be able to take the floor.

DCRs Symposium 2025: Drug consumption rooms, a pillar of harm reduction and human rights

In recent years, Europe has seen early warning signs of an emerging synthetic opioid crisis. While heroin remains the primary opioid of concern, the rise of nitazenes—potent synthetic opioids with unpredictable effects—poses a growing threat. Unlike traditional opioids, nitazenes are often found in counterfeit medications or mixed with other substances, increasing the risk of overdose and complicating harm reduction efforts.

Correlation-European Harm Reduction Network

, is organising a webinar with leading European experts. The webinar will provide an evidence-based overview of the situation around nitazenes in Europe, examine emerging trends, and discuss which policy, healthcare, and harm reduction responses are needed to prepare.

Understanding Nitazenes: What are they, and why are they a growing concern?

Current Trends in Europe: Where are nitazenes being detected, and who is most at risk?

Health and Policy Responses: How can we prepare for and mitigate the risks?

Harm Reduction Strategies: What measures can effectively prevent overdose and support affected communities?

Drug Checking and Surveillance: How can early detection and monitoring systems help?

This interactive webinar will include expert presentations and case studies from different European countries, and a panel discussion to explore the most effective strategies for tackling nitazenes. Participants will have the opportunity to ask questions and share insights during the Q&A session.

Introduction – Tony Duffin (C-EHRN Chair)

European perspective – Joanna de Morais (EUDA)

Community Perspective – Leo Jefferys (EuroNPUD)

This webinar is crucial for harm reduction and healthcare professionals, policymakers, public health officials, and anyone involved in drug policy or healthcare. It will offer a comprehensive overview of current developments and trends related to nitazenes and explore practical responses at European, national, and local levels.

. Upon registration, you will receive a confirmation email with details on how to join the webinar.

Nitazenes in Europe – How should we prepare?

At its bi-annual gathering the European harm reduction movement addressed the multiple challenges of our time: rising populism, shrinking space for civil society, changing drug markets and changing needs of people who use drugs. Watch our film we produced at the conference!

The 6th European Harm Reduction Conference took place at the Palace of Culture and Science in Warsaw, Poland, on 2-4 December 2024. As Alex Lakhov, director of the European Network of People Who Use Drugs (EuroNPUD) mentioned in his speech, to have this conference at this venue, built during Stalin’s years to represent totalitarian power, is a message of defiance. It would make Stalin furious to see that people discuss human rights under the roof of his former palace. Unfortunately it is not only the architecture of totalitarianism that survived but the spirit of Stalin is also alive and well. Civil society activists face the new threats of populism and repressive policies across Europe. The Drugreporter team filmed some key moments and interviewed several participants to learn how harm reductionists respond to new challenges in various European countries – please watch and share our conference video!

The conference marked the 20th anniversary of its main organiser, the Correlation European Harm Reduction Network (C-EHRN). On this occasion, the network published a report with the title “

“, highlighting a selection of key people and organisations. It is my honour that as one of the founder of Drugreporter, I am one of them. Happy birthday Correlation!

This Policy Brief provides an overview of the state of the art regarding Drug Consumption Rooms (DCRs), exploring developments, challenges and needs in their work, as well as an overview of recommendations and examples of good practices for policymakers that wish to support these harm reduction interventions. The paper draws from the activities of the European Network of Drug Consumption Rooms [ENDCR] and, in particular, from the DCR Technical Meetings organised by the ENDCR and the European Union Drugs Agency [EUDA] in 2023 and 

, respectively, in Lisbon and Athens. These meetings gathered DCR representatives from all over Europe to discuss key updates, monitoring, capacity building and advocacy needs and plans.

Creating safer consumption spaces in Europe: Evolving contexts and implications for policy

Drug Consumption Rooms are safe spaces where people can use drugs under hygienic conditions, with support, and without fear of violence or legal repercussions. Today, more than 140 legally-sanctioned DCRs operate in 11 European countries, as well as in Australia, Canada, Mexico and the USA. Join us on a global video tour to discover why they were established, how they support their local communities and how these life-saving harm reduction facilities have evolved over time.

 The role of cities in promoting more just and effective drug policies


Cities are increasingly recognised as crucial drivers of innovation in drug policy. As interest in a new approach to deliver more just and effective drug policies grows, cities face significant challenges in finding room to design new drug policies and in their implementation, due to political resistance, public opposition, and the rise of populist ‘zero tolerance’ and ‘tough on drugs’ politics across Europe.

This webinar will address the important role of cities in forming progressive drug policies and discuss how cities can collaborate and push for positive change in cooperation with international partners and institutions.
