Vienna has one of the more active chemsex scenes in German-speaking Europe, alongside Berlin and Zurich. The scene is concentrated in Vienna's 6th, 7th, and 8th districts and at specific venues and private parties. App-facilitated networks (Grindr, BBRT, Romeo) are the primary organising infrastructure.

Emergency
Call 144 (Austrian ambulance) or 112 if someone is unresponsive, breathing slowly or irregularly, or in cardiac distress. Austrian emergency services focus on the medical situation — call without hesitation.
Services
Aids Hilfe Wien
The primary port of call for chemsex support in Austria. Non-judgmental counselling around drug use and sexual health, harm reduction information specific to chemsex drugs, support navigating addiction treatment, and social work referrals.

Drogenberatung Wien (Vienna Drug Counselling)
Vienna's municipal drug counselling services (sdw.wien). Free, accessible, non-judgmental. Self-referral possible. Outpatient counselling and referral to specialist treatment if needed.
Suchthilfe Wien
The umbrella organisation for addiction services in Vienna (suchthilfe.at). Multiple counselling centres across the city. Subsidised therapy and medical treatment for addiction available.
Grüner Kreis
For inpatient or residential addiction treatment — gruenerkreis.at. General addiction services rather than LGBTQ+-specific.
Drug Checking
Vienna has an established, free drug checking service run by checkit! (checkit.wien). They offer anonymous analysis of psychoactive substances at their homebase (Gumpendorfer Straße 8, 1060) and Lokal (Schönbrunner Straße 222-228), plus counseling. Results are provided anonymously via a sample code.
For those outside Vienna, Energy Control (Spain, energycontrol.org) accepts postal samples from Austria for analysis — particularly relevant for GHB/GBL, where concentration varies significantly between sources.
Testing and PrEP
Regular chemsex significantly increases STI exposure. Quarterly testing is the minimum; many clinicians recommend every two months for regular chemsex participants. PrEP is the appropriate HIV prevention tool in this context.
🚨 Overdose & the Law
If someone is unresponsive, not breathing normally, fitting, or has collapsed — call 112 now. Put them in the recovery position if they're breathing, tell the operator what was taken if you know, and stay with them until help arrives. Getting them medical help is the only priority.
Call 112 / 144. Austria doesn't have a formal "Good Samaritan" law shielding you from drug possession charges, but under § 95 of the Criminal Code (StGB), failing to provide assistance in an emergency is a serious offence. Personal drug possession remains illegal under the Suchtmittelgesetz (SMG), and police may attend the scene, meaning there is a real possession risk. However, your absolute legal duty—and moral priority—is to get medical help. Emergency responders are there to save lives, not to police you. Never let fear of getting in trouble stop you making the call — a life comes first.
