Last published: February 27, 2020

Note: Drugs sold as MDMA (ecstasy) may not contain any methylenedioxymethamphetamine (MDMA); they can be a mix of amphetamine, paramethoxyamphetamine (PMA), ketamine, NBOMe, synthetic cathinones or other substances.

What is MDMA?

Methylenedioxymethamphetamine (MDMA) is an an empathogen, which means it increases an individual’s feeling of empathy and compassion towards others.

MDMA is commonly called and known as ecstasy. However, some pills sold as ecstasy may only have a small amount of MDMA or none at all. Other drugs and ‘fillers’ are often used instead. This makes it hard to know what reactions to expect after taking MDMA or if negative side effects will be experienced.

Other names

Ecstasy, Eckies, E, XTC, pills, pingers, bikkies, flippers, molly.1

Other types of empathogens

How is MDMA used?

MDMA usually comes in a tablet form and is swallowed. The pills come in different colours and sizes and are often imprinted with a picture or symbol.1 It can also come as capsules, powder or crystal.

Effects of MDMA

There is no safe level of drug use. Use of any drug always carries some risk. It’s important to be careful when taking any type of drug.

MDMA affects everyone differently, based on:

  • size, weight and health
  • whether the person is used to taking it
  • whether other drugs are taken around the same time
  • the amount taken
  • the strength of the drug (varies from batch to batch).

The effects of MDMA are usually felt about 20 minutes to an hour after it’s taken and last for around 6 hours.1

You may experience:

  • euphoria
  • feeling energetic and confident
  • large pupils
  • jaw clenching and teeth grinding
  • heightened senses (sight, hearing and touch)
  • excessive sweating and skin tingles
  • muscle aches and pains
  • reduced appetite
  • fast heartbeat
  • increased blood pressure
  • dehydration
  • heat stroke
  • drinking extreme amounts of water (can cause death).1,2,3

If you take a large amount or have a strong batch of MDMA, you may also experience:

  • floating sensations
  • perceptual changes, such as visual and auditory hallucinations
  • out-of-character irrational behaviour
  • anxiety
  • irritability, paranoia and aggression
  • vomiting
  • high body temperature
  • racing heart beat
  • convulsions.2,3

Coming down

In the days after MDMA use, you may experience:

  • restless sleep and exhaustion
  • anxiety, irritability and depression
  • difficulty concentrating.1,2,3

The use of depressant drugs such as alcohol, benzodiazepines or cannabis to help with these ‘come down’ effects, may result in dependence on both types of drugs.

Long term effects

Regular use of MDMA may cause:

  • colds or flu
  • depression
  • needing to use more to get the same effect
  • dependence on MDMA
  • memory and concentration problems
  • financial, work and social problems.1,2

Mixing MDMA with other drugs

The effects of taking MDMA with other drugs − including over-the-counter or prescribed medications − can be unpredictable and dangerous, and could cause:

MDMA + alcohol: increased risk of dehydration and consequently drinking too much water.4

MDMA + ice or speed: increased risk of anxiety and reduced brain functioning due to dopamine depletion. Enormous strain on the heart and other parts of the body, which can lead to stroke.5

MDMA + antidepressants: Drowsiness, clumsiness, restlessness and feeling drunk and dizzy.6


Giving up MDMA after using it for a long time is challenging because the body has to get used to functioning without it. Withdrawal symptoms should settle down after a week and will mostly disappear after a month. Symptoms include:

  • cravings for MDMA
  • aches and pains
  • exhaustion
  • restless sleep
  • agitation
  • trouble concentrating
  • anxiety and depression.7
