Stimulants mask alcohol sedation, so total intake climbs. Cardiac load, dehydration, and blackout risk rise together; the crash often lands after alcohol has already cleared.
Clinical consequences:
- Chest pain / arrhythmia risk under combined load
- Hyperthermia on the dancefloor
- Blackouts with high alcohol totals despite feeling “fine”
- Agitation and harsh comedown after the stack
Practical risk reduction: set a drink limit before dosing stimulants, keep cool breaks, sip water with salt, and do not drive. Points of contact: party support / drug checking projects and Deutsche Aidshilfe.
