From Current to Prospective Service Users: Perceived Harm Reduction Impact of Vienna’s Multimodal Drug Checking Service

Kurzzusammenfassung in leicht verständlicher Sprache

In Wien gibt es Drug Checking Einrichtungen, die Drogen auf Inhaltsstoffe prüfen. In dieser Studie haben wir 23 Menschen, die Drogen konsumieren, interviewt. Die Ergebnisse zeigen: (1) Wissen gibt Sicherheit: Wer weiß, was in der Droge ist, kann besser Konsumentscheidungen treffen. (2) Menschen nutzen das Angebot unterschiedlich: Manche brauchen mehr Beratung, andere weniger. (3) Es wirkt weiter: Nicht nur die Nutzer:innen selbst, sondern auch andere (z.B. Peers) profitieren davon. Damit Drug Checking gut funktioniert, muss es einfach zugänglich sein und auf die unterschiedlichen Bedürfnisse eingehen. Drug Checking kann sichereren Konsum fördern und ist ein wichtiger Baustein der aktuellen Drogenpolitik.

Abstract

Hintergrund und Fragestellung
The evolving landscape of illicit drug markets requires evidence-based harm reduction policies to mitigate health risks for people who use drugs (PWUD). In response, drug checking services (DCS), combining chemical analysis with psychosocial interventions, have been implemented in Austria. While their utilization has shown positive effects on harm reduction behaviors in festival contexts, little is known about how people who predominantly use drugs recreationally engage with and perceive fixed-site DCS and which factors influence their overall impact.

Methoden
This qualitative study evaluated Vienna’s multimodal DCS (mobile and fixed-site). Between June 2024 and January 2025, semi-structured interviews were conducted with 23 PWUD, 12 of whom were current DCS users and 11 prospective DCS users. Including both groups offered a more comprehensive perspective, enabling us to explore the limited reach of DCS and access barriers encountered by certain individuals. Interviews explored risk reduction strategies, service accessibility, and the impact of psychosocial interventions or result communication. Reflexive thematic analysis was employed.

Ergebnisse
Three key themes were developed: (1) “Knowledge creates safety and agency” captures how reliable information on substance identity empowers PWUD to make informed decisions on substance use. (2) “Personal circumstances as key to engagement and impact” illustrates how situational contexts, individual needs, and preferences (e.g., communication method, trust levels, economic situation) shape access to and engagement with DCS. (3) “Social effects beyond the individual” highlights the ripple effects of service use, extending to peers, people who sell drugs, and the broader drug market.

Diskussion und Schlussfolgerung
Our findings show that DCS promote safer use behaviors and risk management among PWUD. To be effective, services must be low-threshold, adapt to diverse needs, and address structural and informational gaps. By centering the voices of PWUD, this research provides actionable insights to help policymakers and service providers design inclusive, accessible, and effective DCS.
