Is This an Emergency?

If you are experiencing serious medical symptoms, seek emergency treatment immediately.

Physical Effects

Because MDMA is a stimulant, immediate side effects include an increase in blood pressure and heart rate, which can be very dangerous for people with underlying cardiovascular health problems. Other effects include uncontrollable muscle clenching, which often results in teeth-clenching or eye twitching. A skin rash similar to acne may also result from ingestion of MDMA.

Effects on Mood

Ingestion of MDMA causes the release of a neurotransmitter called serotonin in the brain, which results in an immediate high. This disruption of the brain's normal serotonin levels can lead to confusion, anxiety, paranoia and sleep problems.

Effects on Mental Ability

Excessive use of MDMA has been shown to damage the serotonin receptors in the brain, reports 2. This brain damage is linked to long-term occurrence of flashbacks and panic attacks and may cause psychosis and personality disorders. Recent tests have shown that long-term MDMA users also exhibit persistent problems with memory recall.

Life-Threatening Effects

In rare cases, MDMA use can cause rapid peaks in body temperature. When this occurs in the hot, crowded conditions of a club or rave, severe dehydration and heart or kidney failure may result. Some fatalities have been linked to MDMA use, according to the National Institute on Drug Abuse 1.


Users of MDMA may become physically dependent on and addicted to MDMA. One survery found that 43 percent of MDMA users showed signs of dependence, reports the National Institute on Drug Abuse 1. Withdrawal symptoms include loss of appetite, depression, fatigue and problems concentrating.
