MDMA can affect body temperature, cardiovascular function, mood, and the nervous system. This educational guide focuses on major safety concerns and warning signs.
Heat and Temperature
MDMA can interfere with the body’s ability to regulate temperature. Hot environments and prolonged physical activity can increase the risk of overheating.
Hydration Can Be Complicated
Both dehydration and excessive water intake can be dangerous. Fluid needs vary with circumstances, and severe symptoms should never be managed by guessing at home.
Interactions
MDMA can interact with other psychoactive substances and medicines. Substances that affect serotonin may create additional concerns, including serotonin syndrome.
Emergency Signs
Very high body temperature, seizures, severe confusion, loss of consciousness, difficulty breathing, chest pain, or extreme agitation require urgent medical help.
