In New Zealand some substances being sold as MDMA are actually synthetic cathinones (bath salts). These drugs can have more unpleasant and unpredictable effects than MDMA.

Key things to know

Use drug checking services to make sure it isn’t a different drug. If you can’t get to drug checking services, use a reagent test

Drug checking info

MDMA is usually swallowed as a pill or mixed into water. If swallowing, wait an hour for the effects to kick in before deciding to take more

Start low, go slow

If snorting, use clean straws and surfaces and rinse out your nose with a saline rinse

Safer snorting

If you can’t test it, take a lower amount in case it is something else

Stay hydrated and look after yourself during the comedown

Comedown tips

MDMA is a stimulant that comes as powder or crystals that are white or brown, or as pressed pills.

How does MDMA make you feel?

MDMA can give you the feeling of euphoria or make you more emotional and empathetic. It can also make you feel dizzy, sweaty and agitated. Remember, a low dose for one person can be a high dose for another as people’s bodies process drugs differently. 

Keep in mind that, when mixed with alcohol or other drugs, MDMA can have different effects to those listed below. Pressed pills can often contain other fillers or drugs that can also alter the effects of MDMA.

See Know Your Stuff NZ's pill library for MDMA pills that are in the NZ market and contain other substances, no MDMA or more than one dose.

A Reddit user describes the ups and downs of a lower dose of MDMA:

“I feel like when each wave hits, I panic for a few seconds as I think I am coming down and then I feel a roller coaster drop in my gut and I can feel and hear this rising electrical energy through my body and it explodes in my brain and this wave of warmth and euphoria slowly flows through my body starting in my chest.”

How much MDMA do people usually take?

There are no publicly available tests to measure how strong your drugs are, so often people start low and go slow.

This information is not a recommended dosage amount. It can't take account of your specific circumstances. Drugs affect everybody differently, depending on things like your body size, any other drugs you’ve taken, what you have eaten, where you are, and how you're feeling. Find out more under the safer using section. 

Remember, drug checking can tell you what is in your drugs, but can’t tell you how strong they are.  

The information below is from other websites about how much people commonly use overseas. It is not a recommendation and typical usage in Aotearoa may be different.

How much MDMA do people usually take - swallowed (from

Light 20 - 80mg
Common 80 - 120mg
Strong 120 - 150mg
Heavy 150mg+

How much MDMA do people usually take - snorted or shelved (from

Light 30 - 70mg
Common 70 - 120mg
Strong 120 - 165mg

How can you be safer when using MDMA?

MDMA comes in many different forms and is taken in many different ways. It can also effect everyone differently at different doses. However you are using MDMA, it is always a good idea to think about the things you can do to be safer. 

Crush, mix and measure your MDMA.                                                                                                                 MDMA is often not evenly mixed in pills or baggies. Crushing it and mixing helps to evenly distribute the drug so you don't end up with one part of the pill or baggie being a lot stronger than another. Measuring out your dose helps to avoid negative effects. Check out our article on this for more information.

If you are swallowing MDMA, wait an hour before re-dosing. 
Swallowing is the most common method of taking MDMA. It delivers the drug more slowly into your bloodstream, which can reduce your risk of overdose. However, because it releases the drug more slowly, it is good to wait 1 hour before re-dosing as you will not feel the effects right away. People may also take MDMA by snorting, smoking, injecting or taking it rectally (‘boofing’ or ‘shelving’). These methods deliver the drugs faster to your body, which can result in an increased risk of overdose.

Take care if you are snorting MDMA. 
Snorting MDMA can result in damage to your nose, especially if you do it often. If you choose to snort, try to take longer breaks between using this way to reduce the damage. Use a clean straw and surface when snorting and do not share tools with others. It is best to avoid snorting MDMA that has been pressed into pills, as it is likely to be mixed with other fillers that can be dangerous when snorted. You can also do a nasal saline rinse after snorting to clear your nose. 

Test your MDMA to make sure it isn't a different drug. 
Before you use, it’s a good idea to have your MDMA checked to see if there are other drugs like synthetic cathinones (bath salts) mixed with it. There are two ways in New Zealand to check what is in your drugs – going to a drug checking clinic where they use a spectrometer or using reagent tests yourself. For MDMA, you should use more than one reagent test as reagent tests only show if there is MDMA in the drug, not whether it is mixed with something else.

If you can't test your MDMA, start with a low dose. 
As MDMA is commonly mixed with or substituted with other, more dangerous drugs it is a good idea to start low  if you aren't sure. Many of the drugs sold as MDMA like eutylone are stronger than MDMA, so taking a smaller dose can reduce your chance of overdosing. Taking a smaller dose will also reduce the unpleasant effects if you have taken a drug that is not MDMA. 

Stay hydrated. 
MDMA can make you really active, which can dehydrate you, especially if you are dancing in a hot environment. Try to replace the water you lose without going too overboard - a glass or two an hour is usually enough.

What do comedowns from MDMA feel like, and how can you feel better?

Most people will experience some sort of comedown from MDMA. It usually starts 6–12 hours after taking it and can last for about 1–4 days. How bad the comedown is will depend on how much you took, whether you re-dosed and if you also took it with alcohol or other drugs.

They can talk you through the next steps.

If you experience psychosis, have serious disturbances in mental abilities (delirium), have a high fever, act violently, attempt suicide, have a seizure, become unresponsive or lose consciousness, these are signs of an MDMA overdose. You or the people around you should act quickly. Call 111.

Some people drink too much water when on MDMA so you may also experience symptoms of water intoxication – faintness, extreme confusion and trouble moving.

If you experience unexpected or concerning effects from MDMA you can notify High Alert to help keep others safe.

One Reddit user describes having a bad experience on MDMA at a New Year’s Eve event:

“About 30 minutes after taking the molly, I started to feel it, at first I was just more energetic but within a couple minutes I lost control of everything. All of a sudden I couldn’t feel anything in my body at all, like I was completely numb. Along with this I couldn’t move any part of my body and felt extremely heavy, I couldn’t even hold my head up or stand.”

What are the long-term effects of using MDMA?

Most people who use MDMA may only use it from time to time like at festivals, events or parties. However, some people use MDMA regularly and over a long period of time, which can lead to more long-term effects.

If you are using MDMA nasally, rectally or by injecting (even if it is just from time to time), this can cause long-term damage to your body. For more information on how to be safer when using drugs and alcohol, see Safer using.

MDMA can affect the serotonin system in your brain, and this can contribute to mental health conditions like depression and anxiety over time. At higher doses or in longer periods of use, MDMA can cause problems with memory, behaviour, personality changes and learning difficulties. MDMA has also been linked to brain events like strokes. 

If you are using MDMA regularly, it might disrupt your sleep and appetite (feeling very hungry or not hungry at all). You may also be more likely to make impulsive decisions, have trouble concentrating or have low mood.

How do you manage withdrawal from MDMA?

See the 'Making changes' page for more information on how to Manage withdrawal from drugs and alcohol.

MDMA is often talked about as not being addictive, and while it is not as addictive as other drugs, some people do become dependent on MDMA.

There are lots of reasons other than addiction that people want to stop using MDMA. You may want to take a break because you are using it more than you would like or find you are not having fun without taking it.

Below are some things to be aware of if you are taking a break or stopping MDMA use, especially if you have been using it regularly. These symptoms may be different if you have been using other substances that have been sold as MDMA or if they are mixed. Synthetic cathinones (sometimes called bath salts) that are often sold as MDMA have more unpleasant and unpredictable effects from cutting down or stopping.

You might: 

  • Have cravings to use MDMA
  • Have sore muscles or muscle cramps
  • Experience changes in appetite
  • Feel antisocial
  • Feel irritable, agitated, anxious or low
  • Have trouble concentrating or thinking
  • Have problems sleeping
  • Feel tired
  • Have memory problems

You can try:

  • Follow a tapering plan from a health professional to reduce your dose slowly.
  • Consider counselling or support groups if feelings of anxiety and depression are getting worse.
  • Lean on a support network of friends, family and professionals.
  • Stick to a routine – waking up, eating well, keeping active and rewarding yourself with things that bring you joy.
  • Practise mindfulness by writing down your feelings, doing breathing exercises or meditating.

If your symptoms worsen or don't go away, or you have ongoing insomnia, have heart palpitations, have a panic attack or hallucinate, call a doctor or Healthline (0800 611 116).

You can talk to your doctor about:

  • other medicines to help you get through withdrawal
  • rehab or withdrawal clinics in your area – visit Health Point to see what services are available.

If you feel severely emotionally distressed, have chest pain, experience psychosis or have a seizure, these are signs you could be experiencing severe withdrawal or that something serious is going on. You or the people around you should act quickly. Call 111.

How can MDMA affect your daily activities?

Even at low doses, MDMA can affect your work and everyday activities. The effects of MDMA usually peak 1–2 hours after taking it depending on how it’s used (swallowed, snorted) and can last for 4–5 hours before the effects wear off. If you take a larger dose, use regularly or mix with alcohol or other drugs, the effects can last a lot longer.

MDMA can cause changes in experiences so that the user has a change in perception or hallucinates, feels dizzy or is sensitive to sensations and surroundings (such as light). It can be unsafe to drive or operate heavy machinery when experiencing an MDMA high. It can also make you feel overly emotional, agitated, jittery or anxious, which means that interacting with others can be difficult.

Will MDMA show up on a drug test?

MDMA is usually tested for using hair, urine, saliva (spit), sweat or blood. The detection timeframes may change depending on how much MDMA you take and how often you take it. Generally, MDMA can be detected for 1–4 days in urine, 1–4 days in saliva, 1–2 days in blood, 2 days in sweat and up to 90 days in hair. It is important to remember that every person’s body is different and will process drugs differently.
