Effects

We have listed the most common effects of MDMA. Please note that everyone can be affected differently, and this is not an exhaustive list. Not everyone experiences these effects, and other effects are possible. Remember that negative side effects of MDMA increase with higher doses.

The effects entail (from positive to negative):

  • Mood lift (mild to extreme)
  • Talkative and sociable
  • Increase in energy
  • Feelings of comfort and belonging
  • Increased empathy
  • Increased appreciation of music
  • Increased pleasure from the sense of touch
  • Decreased appetite
  • Visual distortion: mild hallucinations
  • Rapid involuntary eye jiggling
  • Restlessness, nervousness and shivering
  • Change in body temperature regulation
  • Unexpected emotions
  • Strong desire to take more MDMA when coming down (tip: after a certain point during the comedown, taking more will you not lead to positive effects. It only worsens the hangover. Abstain from redosing at the end of the night.)
  • Mild to extreme jaw clenching, tongue and cheek chewing, and teeth grinding (tip: use chewing gum to avoid teeth grinding and try magnesium tablets to reduce clenching)
  • Difficulty concentrating
  • Impaired ability to focus eyes/blurred vision
  • Inability to fall asleep when physically tired
  • Erectile dysfunction and difficulty reaching orgasm
  • Increase in body temperature, dehydration (tip: drink around 500ml of water per hour. Excessive water decreases salts in the body, so be careful not to drink too much).
  • Nausea and vomiting

* Much more common among first-time users

Dose and Onset

How? How much? When? For how long?

Read our section on dosing and tolerance in ME for more information.

As with any drug, the correct dose for you depends on factors such as weight, gender, metabolism, whether you have taken the drug recently or not, amongst many others.

How you take it matters...

MDMA usually comes in a powder or pill form, and is ingested orally. However, it is also sometimes taken nasally, but this is not recommended, as it decreases the length of the experience, cause nasal pain and can cause a more severe comedown.

How much?

  • Small/sensitive people: 60-90mg
  • Recommended dose for most people: 75-125mg
  • Large/less sensitive people: 110-150mg
  • Strong dose: 150-200mg
  • Heavy dose: 200mg+

Use a scale to measure the exact amount of MDMA you would like to take.

When do the effect kick in and for how long?

The START time below is when you will usually begin to feel the effects of MDMA from the time when you first take it. DURATION is roughly the length of time you will experience the effects, after which the effects will start to wear off and you might start to feel the comedown effects.

  • Onset: 20–70 minutes (depending on the form of the MDMA and how much food you have eaten)
  • Duration: 3–5 hours
  • Normal after-effects: up to 24 hours after

WARNING: pills in the UK and Europe contain a very high concentration of MDMA. This can lead to accidental overdoses. We recommend that you try half a pill first as it might have much more MDMA than you expect.

How often can I take it?

The Three Month Rule

MDMA works by causing large amounts of serotonin to be released, along with other neurotransmitters like dopamine. After using MDMA, your serotonin levels are lowered, and it takes a long time for your brain to build more serotonin. If you take ecstasy on a regular basis, you may be releasing and depleting your serotonin before it has a chance to fully replenish itself. This means you will be operating on lower-than-normal serotonin levels most of the time, and this can lead to depression or worsen depressive symptoms. It is recommended that you leave at the very least 1–2 months between uses, ideally 3. Save MDMA for special occasions or events only, and use it very sparingly.

Tolerance and loss of effecctiveness

Just as if you take too high a dose, consuming MDMA too often also seems to produce an irreversible loss of potency.

Risks

Long-term use and health risks

There are studies that indicate brain toxicity can occur after MDMA use. However, there is little or no knowledge of what the consequences are.

Most of the MDMA-related injuries are due to dehydration caused by increased sweating and overheating. Make sure to drink water during the night, but not too much as too much water can lead to health risks of its own.

Dependence

MDMA is not as addictive as other stimulants or depressants. However, like any other drug, it is possible to become dependant if it becomes a habit. Please read our information on dependence in our Essentials page for more information.
