Chemsex — the use of specific drugs during sex, primarily among gay and bisexual men — is present across Germany's major cities, with Berlin having one of the most established chemsex scenes in Europe. Germany also has some of the best-developed chemsex support services in the world, built by organisations that have been engaging with this issue since the early 2010s.
This guide covers what chemsex support looks like in Germany, who provides it, and how to access it without shame.
The Chemsex Landscape in Germany
The drugs most commonly involved in chemsex in Germany:
- Crystal methamphetamine (Tina, Crystal) — particularly common in Berlin's scene
- GHB/GBL (G) — sedative/euphoric; narrow margin between recreational and overdose dose
- Mephedrone (Meph, 4-MMC) — cathinone stimulant; less widespread than in the UK
- Cocaine — stimulant; common but lower association with extended chemsex sessions
- Poppers (amyl/butyl nitrite) — legal in Germany; commonly used alongside other drugs
Berlin has a particularly visible crystal meth-associated chemsex culture, connected to the city's club and sex venue scenes. Hamburg, Cologne, and Munich also have established scenes, though typically less visible.
If It's an Emergency
Call 112. If someone is unresponsive, having a seizure, or you suspect GHB/GBL overdose (overdose can happen very quickly with G, often indistinguishable from normal sedation until it tips over), call 112 immediately.
Germany has de facto Good Samaritan protection — calling for help for someone having a drug-related emergency is overwhelmingly the right thing to do and callers are not typically prosecuted. Do not leave someone alone.
GHB/GBL overdose signs: unresponsive but appears to be "sleeping", cannot be woken, irregular breathing. Recovery position and 112.

Harm Reduction Principles
If you're using drugs in sexual contexts and aren't ready to stop, harm reduction practices reduce risk:
For GHB/GBL:
- Never mix with alcohol — the combination dramatically increases overdose risk
- Track your doses carefully — the recreational window is narrow
- Never use alone
- Tell a trusted person what you're taking and where you are
For crystal meth:
- Extended use significantly increases HIV transmission risk (PrEP efficacy can be affected by erratic dosing when intoxicated)
- Extended sessions create vulnerability to sexual coercion — have a plan to check in with a friend
- Post-session crash can trigger severe depression — have support available
For all drugs:
- Test your drugs if possible — Germany has drug checking services in some cities. Check with your local Aidshilfe for current availability.
- Know your starting state — avoid using when already mentally fragile
- PrEP still works but must be taken consistently — use a pill alarm
The Link Between Chemsex and HIV/STI Risk
This is not about judgement — it's practical information. Studies consistently show elevated HIV and STI acquisition rates during chemsex, for several reasons:
- Drugs reduce inhibitions around condom use and communication
- Extended sessions increase mucosal trauma
- Crystal meth specifically is associated with compulsive sexual behaviour and reduced ability to make planned choices
- Sharing injecting equipment (slamming) carries very high transmission risk
Harm reduction doesn't mean avoiding chemsex entirely — it means being as informed and prepared as possible.
If you're having chemsex and are HIV-negative, PrEP is particularly important. If you've had a potential HIV exposure, go to a Notaufnahme for PEP assessment.
Accessing Medical Support
If your drug use has become dependent or harmful, German healthcare can help:
- GP (Hausarzt): Can refer you to an Entzugsklinik (detox clinic) or a Drogenberatung (drug counselling service)
- Schwerpunktarzt: Can coordinate care if HIV/STI status is relevant
- Drogenberatung: Specialist drug counselling services exist in every German city, independent of the queer-specific services above
GKV covers addiction treatment including detox and residential rehabilitation. Ask your GP for a referral.
