MDMA and Amphetamine
Stimulant stacking.
Why this happens
Compounds overheating, cardiac strain, and neurochemical load, and intensifies the crash. A genuinely risky pairing.
What this means in practice
Best avoided. If they are combined anyway, keep doses low, watch the person closely, and be ready to call for help.
Warning signs - get help
Call your local emergency number straight away if you notice any of these:
- A body temperature that stays high
- Chest pain or a racing, pounding heart
- Confusion, collapse or a seizure
Information, not medical advice. Threshold does not promote or encourage MDMA use. This exists so that people who make their own choices can make safer, better-informed ones. It is not a substitute for professional care.
