MDMA is a stimulant-hallucinogenic research chemical. MDMA is not the same drug as ecstasy. Ecstasy is usually combined with other substances, from caffeine to amphetamine!
The same pill/powder may take 3 hours to have and effect and 30 mins for someone else. Wait to feel the effects and then decide whether you want to redose.
Stay hydrated, but don't drink too much. 250–500ml (one or two standard glasses) per hour is recommended.
MDMA affects your body temperature. Take a break: go outside or sit down from time to time to cool down.
Here are the most common effects, not everyone necessarily experiences all of them every time they consume the drug and other effects not listed might be felt. The likelihood of experiencing negative effects is far greater at high doses.
The effects are (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
- Change in body temperature regulation
- Unexpected emotions
- Strong desire to take more MDMA when coming down
- Mild to extreme jaw clenching, tongue and cheek chewing, and teeth grinding
- 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
- Nausea and vomiting
Dose and onset
How? How Much? When? For how Long?
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.
Read our section on dosing and tolerance in ME for more information.
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.
- Small/sensitive people/first timers: 60-90mg
- Recommended dose for most people: 75-125mg
- Large/less sensitive people: 110-150mg
- Strong dose: 150-200mg
- Heavy dose: 200mg+
Guideline by body weight: 0.7mg per lb, or 1.54mg per kg
Optional redose: half of the original dose, 2–3 hours in.
Use a scale to measure the exact amount of MDMA you would like to take.
When do the effects 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 effectiveness
Consuming MDMA too often decreases the potency of this drug on your body. This may lead to consuming larger amounts of MDMA. Again, save MDMA for special occasions or events only, and use it very sparingly.
There are certain precautions you should take before doing MDMA. The advice below helps you to be physically and mentally prepared before doing it. Furthermore, we want you to be safe, and just in case you have a bad experience or some of the unwanted side effects associated with MDMA, we have also provided information on how to take care of yourself when you are in full swing. Finally, there are those uncomfortable or undesirable effects after the high have worn out, we will provide you with some practical tips on how to have a better calm down and help you to reduce the harm done to your body and brain.
Head over to our ME section if you would like to know more about harm reduction.
Test the drug
MDMA and ecstasy are often mixed with other chemicals, from caffeine to methamphetamine. We recommend that you always test your pills using a drug testing kit. Depending on the country you're in, there are places where you can send samples of your pills to be tested. Another recommended source is Pill Reports, where you can search for an ecstasy pill by its stamp and appearance. However, this is not a foolproof way to making sure that your pills are safe.
Accidental deaths have occurred due to ingesting compounds such as PMMA in a pill that was thought to be MDMA. We know some people cannot be bothered to test, but it is becoming increasingly important to do this in order to stay safe.
Check the interactions
Check our drug interaction chart above!
Drink water (but not too much!)
Drink around 500 ml of water (2-3 glasses of water) per hour to avoid overheating and dehydration. Excessive water decreases salts in the body, so be careful not to drink too much.
Take a break from dancing
MDMA can change your body temperature regulation, while dancing increases your body temperature. These combined can lead to heat stroke, so take a break from dancing from time to time to cool down.
A common mistake which can lead to a bad experience (or even to hospitalisation) is taking another dose of MDMA because the first one did not have an effect. This leads to ‘coming up’ twice as hard, which is very dangerous. MDMA takes a long time to digest and absorb, so be patient, and wait for it to kick in. After a certain point during the comedown, taking more will not lead to positive effects. It only worsens the hangover. We recommend that you abstain from redosing at the end of the night.
Find some chewing gum
Use chewing gum to avoid teeth grinding and try magnesium tablets to reduce clenching
Emergencies and overdosing
How to know if someone took an overdose:
- Serotonin syndrome: increased heart rate, shivering, twitching, over-responsive reflexes, extremely high temperatures
Do not doubt to call a paramedic if you feel any of these symptoms. You will not get into trouble.
The MDMA hangover, or comedown, varies from person to person and is dependent on the amount taken. The effects can also last from 1 up to 14 days after use.
The after-effects include:
- Fuzzy memory
- Decrease in attention or difficulty concentrating
- Some people feel happier in general and more focused.
- Mild to strong depression
Some people experience a ‘loss of magic’ after using MDMA after a couple of uses, meaning the drug doesn’t feel as good as the first few times. However, this does not happen to all people. If MDMA is taken on successive days or weeks, then the negative and comedown effects are worsened.
Additional harm reduction advice:
Drink plenty of water before and after, and we also recommend taking vitamin supplements. Here is RollSafe's
guide to supplementing vitamins with MDMA:
6 hours before
- 200mg (2 pills, normally) Magnesium Glycinate
- A glass of grapefruit juice
1–3 hours before:
- 100mg Na-R-ALA (when buying, make sure it is Na-R-ALA, not R-ALA)
- 200mg Magnesium Glycinate
- 1000mg Vitamin-C (e.g. 1x Emergen-C packet)
- 100mg Grape Seed Extract
- A Glass of grapefruit juice
- 500mg ALCAR
- 400mg EGCG
- 100mg CoQ10
30 mins before:
- 1x Tums/Rolaids (unlike the other supplements listed here, this is not for harm reduction. Instead, it increases stomach alkalinity which prolongs the roll)
2 hours after dosing:
4 hours after dosing:
- 100mg Na-R-ALA
- 5-10mg Melatonin
The following 3-7 nights:
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.
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 ME page for more information.
