How are they used?
PMA and PMMA are usually swallowed and can also be snorted or injected.
Effects of PMA and PMMA
Use of any drug can have risks. It’s important to be careful when taking any type of drug.
PMA and PMMA affect 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 environment (where the drug is taken)
Effects may include:
- moderate stimulation
- seeing colours and shapes
- heightened senses (sight, hearing and touch)
- dizziness
- dry mouth and dehydration
- increased bodily temperature
- teeth grinding
- increased sweating
- increased heartbeat and blood pressure
- irregular eye movements
- muscle spasms
- decreased appetite
- nausea and vomiting.4-7
Impact of mood and environment
Drugs that affect a person’s mental state (psychoactive drugs) can also have varied effects depending on a person’s mood (often called the ‘set’) or the environment they are in (the ‘setting’):
- Set: a person’s state of mind, previous encounters with drugs, and expectations of what’s going to happen. For example, feelings of stress or anxiety before using PMA/PMMA may result in an unpleasant experience.8
- Setting: the environment in which someone consumes PMA/PMMA – whether it’s known and familiar, who they’re with, if they’re indoors or outdoors, the type of music and light. For example, using PMA/PMMA in a calm, quiet and relaxed environment can lead to, or contribute to, a pleasant experience but being in a noisy, crowded place may result in a negative experience.8
Overdose
If you take a large amount or have a strong batch, you could overdose.
PMA and PMMA can cause death. Call an ambulance straight away by dialling triple zero (000) if you, or someone else, has any of the following symptoms:
- extremely high body temperature
- convulsions and seizures
- difficulty breathing
- nausea and vomiting
- kidney failure
- severe hyperthermia
- coma.9
Ambulance officers do not need to involve the police.
Coming down
In the days after using PMA/PMMA, you may experience:
- difficulty concentrating
- anxiety, irritability and depression
- restless sleep and exhaustion
- loss of appetite
- paranoia (feeling suspicious and frightened).10
Long term effects
The long-term effects of PMA and PMMA have not yet been established but some research indicates they may have similar long-term effects to ecstasy.11
Tolerance and Dependence
It is possible to build up a tolerance to PMA/PMMA, which means you need to take larger amounts of it to get the same effect. However, there have been no reports of any physical withdrawal symptoms and dependence. There is potential for psychological dependence to develop (desire to keep taking the drug despite the risks).12,13
Mixing PMA and PMMA with other drugs
Mixing PMA/PMMA with other drugs can have unpredictable effects and increase the risk of harm.
- PMA/PMMA and alcohol: can increase the effects of PMA/PMMA making it more likely to increase negative effects.
- PMA/PMMA and cannabis: can increase anxiety levels and the risk of thought loops and paranoia which can lead to a negative experience.
- PMA/PMMA and ice/speed/cocaine: can cause fast heart rate, high blood pressure, constriction of the blood vessels and in extreme cases heart failure.7,12
Use of more than one drug or type of drug consumed at the same time is called polydrug use.14
More on Polydrug use
Polydrug use is a term for the use of more than one drug or type of drug at the same time or one after another. Polydrug use can involve both illicit drugs and legal substances, such as alcohol and medications.
Reducing harm
There are ways you can reduce the risk of harm when taking PMA/PMMA:
- Start with a lower dose first and wait 2 hours before taking any more
- Avoid taking higher does of PMA/PMMA. This has been known to be lethal.
- Avoid using if you have an existing heart condition, blood pressure problems, epilepsy or asthma.
- Avoid mixing with other drugs
- Drinking too much water while taking PMA/PMMA is dangerous but it is also important to maintain hydration. If dancing, take regular breaks to cool down and drink around 250-500ml of water per hour.15
