Users entering treatment for heroin in Europe, 2023 or the most recent year available

Description

This data visualisation was originally produced for the European Drug Report 2025: Trends and Developments.

Apart from trends, data are for all treatment entrants with heroin as the primary drug – 2023 or the most recent year available.

Trends in first-time entrants are based on 26 countries. Only countries with data for at least 5 of the 6 years are included in the trends analysis. Missing values are interpolated from adjacent years. Because of disruptions to services due to COVID-19, data for 2020, 2021, and 2022 should be interpreted with caution. Missing data were imputed with values from the previous year for Spain and France (2023) and Germany (2019).
