Methamphetamine is a very strong stimulant from the amphetamine family that speeds up your brain and body. It can give you an initial feeling of euphoria, but it can also make you feel paranoid, aggressive, and confused.
Methamphetamine also affects your reaction time and judgement. This can lead to an increased risk of accidents on the road or at work.
The effects of methamphetamine can last for up to 12 hours.
Methamphetamine increases dopamine in your brain. Dopamine is a chemical linked to feeling good and rewarded. It creates feelings of happiness and high energy, but these effects do not last. They are usually followed by a harsh comedown.
The real danger? Methamphetamine gradually destroys your brain's dopamine receptors, making it harder to feel pleasure over time.
This starts a vicious cycle: needing more methamphetamine to feel the same high, while causing more damage to your brain with each use. Methamphetamine use is hard to control, stop or cut down because of this.
As well as damaging your brain, methamphetamine can damage your heart, your lungs, your teeth and skin.
Why methamphetamine is so addictive
Methamphetamine can contribute to significant mental and physical health issues over time including:
- tooth loss and mouth sores (‘meth mouth’)
- skin sores and scarring because of intense itching
- damage to your heart and lungs that can lead to conditions like heart disease and heart attacks
- depression, anxiety, mood swings, and agitation
- symptoms of psychosis such as paranoia, hallucinations, or delusions
- sleep problems
- memory loss.
What to do if someone is having an overdose
Most people do not use methamphetamine, but if it is offered in a social situation, it can be hard to say no. Being clear in your intention to say no is the first step. There are lots of practical strategies available to help you follow through on your intention:
- Keep your answers short and confident.
- Have an excuse ready if you want to.
- Change the subject, or suggest doing something different.
- Have a buddy system.
- Just leave.
Be kind to yourself. Keep doing the things you love and stay connected to the people you care about. It could be sport, being outdoors, or spending time with friends and whānau. Anything that helps you feel good will help you stand strong against the risk of meth for yourself and those around you.
The New Zealand Drug Foundation has resources for schools, community groups, parents, and caregivers to help with talking about drugs, and supporting young people to make healthy decisions.

You might have seen images of meth users that show dramatic physical changes like missing teeth or extreme weight loss. It is true that this can happen over time, but there are much earlier signs that someone could be using meth. These include:
- changes in sleep or eating patterns
- being unusually alert or physically active
- changes in behaviour like unexpected outbursts or mood swings
- changes in social circles
- paranoia or hallucinations.
If you notice these kinds of changes, having a kōrero early on can help protect friends and whānau from meth. The Level has tips to help you plan your conversation.
