Erratum

In the article by Bretteville-Jensen and Nesse entitled “Non-Prescribed Use of Opioid Agonist Medications and Associations with Non-Fatal Overdoses: A Repeated Cross-Sectional Study across a Decade of Reduced Monitoring” [Eur Addict Res. 2025; https://doi.org/10.1159/000547909], an error was introduced during production concerning the license. The article was mistakenly published under a CCC license instead of the intended CC BY 4.0 license.

The original article has been updated.
