Syabu, the Malaysian name for crystal methamphetamine, is the substance behind most of the addiction cases recorded in this country. In 2024, amphetamine-type stimulants, which are mostly syabu, accounted for 139,909 of the cases recorded by the National Anti-Drugs Agency (AADK), roughly seven in ten, and the agency recorded 191,832 people in treatment across 2025. Most of them were between 19 and 39.
It is also the substance families find hardest to understand, because it does not look like the drinking or heroin use of an older generation. This is what we tell families who call about it.
Why it takes hold so quickly
Methamphetamine releases a flood of dopamine, the brain's reward signal, far larger than food, sex or any ordinary pleasure produces. The first experiences are intense: energy, confidence, no need for sleep, a feeling of being capable of anything. That is why it spreads through workplaces that reward long hours as readily as through nightlife.
With repeated use the brain adjusts. Ordinary life stops producing pleasure, the drug is needed to feel normal, and the periods between use are marked by exhaustion and low mood. At that point a person is no longer using to feel good; they are using to avoid feeling terrible. That is dependence, and it is a health condition, not a weakness.
What families usually notice
- Sleep that makes no sense: days awake, then a day or two of sleeping through. The pattern is one of the earliest signs.
- Weight loss and a changed face, as appetite disappears and skin, teeth and eyes change over months.
- Mood that swings between two states: talkative, restless and over-confident, then flat, irritable and withdrawn.
- Money and belongings that do not add up. Syabu is not cheap at the volumes dependence requires, so items go missing and explanations get thin.
- Suspicion and fear: paranoia, checking windows, accusing family members, hearing things. Psychosis is a recognised effect of heavy use and needs medical attention, not argument.
- A new circle: old friends gone, new contacts who are never introduced.
You do not need to be certain of any of this to call us. Families rarely are.
The first weeks without it
Stopping methamphetamine is not medically dangerous in the way that stopping alcohol or benzodiazepines can be, but it is hard, and it is where most attempts to stop at home fail.
The crash comes first: days of deep sleep, hunger and heavy low mood. Research summarised by NIDA puts the peak of withdrawal at two to three days after the last use, easing over about a week. What lingers for weeks and sometimes months is the part families underestimate: low mood, anxiety, poor concentration and strong cravings, often triggered by places, people and stress. This is why the first phase of a stay at Salus is built around sleep, food, routine and medical review before therapy proper begins, and why a 90-day programme is the length we work to.
Where psychosis is present, it usually settles as the drug leaves the system, but it needs psychiatric assessment, which is why every guest is seen by a psychiatrist on arrival.
What treatment that works looks like
There is currently no approved medication that treats methamphetamine dependence itself. Treatment is psychological and behavioural, and the evidence is clear about what helps:
- Cognitive behavioural therapy and motivational interviewing are the core. The Matrix Model, a structured programme built specifically for stimulant dependence and used at Salus, combines these with relapse-prevention work, family education and drug testing over several months.
- Contingency management, which gives small, immediate rewards for verified abstinence, has the strongest evidence of any single approach for stimulants. At Salus this is woven into the living prescription: progress earns real activity, real responsibility and real freedom, not tokens.
- Many people who use syabu are also carrying depression, anxiety, trauma or ADHD-type difficulties. If those are not treated, the drug tends to come back to treat them.
- Cravings months after stopping are normal. What decides the outcome is whether the person has sleep, routine, people and purpose to hold the change, which is the whole point of the Social Prescription Model.
- Families who understand the crash, the cravings and the timeline stop reading a bad week as a failed treatment.
What to do today
If someone is psychotic, violent or has collapsed, call 999 first.
For everything else, the next step is a confidential conversation. You can call or message Salus without the person knowing, describe what you are seeing, and hear from someone who has worked with syabu dependence for years what the options are. If you are not sure how to raise it with them, our guide on talking to someone you love about getting help is a good place to start.
Syabu dependence is treatable. The people we see recover take longer than a fortnight and rarely manage it alone, but they do recover.
