Magic mushrooms are wild fungi that contain psilocybin, a drug that causes hallucinations and a strong change in how people see, hear and feel for about four to six hours. They are rarely addictive in the way heroin or alcohol is, but they can trigger panic, risky accidents and lasting mental health problems, and in Malaysia possessing or selling psilocybin is an offence under the Dangerous Drugs Act 1952.
This guide explains what magic mushrooms do, the real risks, how to tell when use has become a problem and where adults in Malaysia can get help.
What magic mushrooms are
The Alcohol and Drug Foundation describes magic mushrooms as naturally occurring fungi eaten for their hallucinogenic effects. The body turns psilocybin into psilocin, which is the chemical that acts on the brain. They look much like ordinary mushrooms and are usually eaten, fresh or dried, or brewed into a tea.
Effects usually begin about 30 minutes after eating them, or within 5 to 10 minutes as a tea, and last around four to six hours. People call this a "trip".
What people feel
- changes in mood, thinking and sense of time
- colours, sounds and shapes that seem distorted, and hallucinations
- feeling giggly, excited or deeply calm, or confused and anxious
- nausea, vomiting and stomach discomfort
- a fast or irregular heartbeat, sweating, chills and a raised temperature
The next day people often feel tired, low or anxious, and some get headaches.
Magic mushrooms in Malaysia
Magic mushrooms are less common here than syabu, ganja or heroin, but they are turning up more. Experts from Universiti Sains Malaysia and Universiti Kebangsaan Malaysia told The Sun that they are sold through social media, that there have been no official seizures of psilocybin so far, and that they are not part of routine drug screening.
Products sold under the mushroom name are often not what they claim. In 2024, The Star reported that USM's National Poison Centre tested a vape line sold as "Magic Mushroom" and found synthetic drugs but no psilocybin; users had become delirious and behaved in severely abnormal ways. George Town police told RTM in 2023 that synthetic "mushroom" drugs in vapes and cigarettes had become a trend among young people. Bukit Aman narcotics police told Bernama in 2021 that drugs made from mushrooms were mostly sold as liquids and mixed into drinks at parties. Our guide to vaping addiction explains why drug-laced vapes are a growing worry.
So a person who thinks they are taking "just mushrooms" may be taking something stronger and less predictable.
The risks
Poisonous look-alikes
FRANK, the UK government's drug advice service, says the biggest danger to health is eating a poisonous mushroom by mistake. Some wild mushrooms that look similar can cause serious illness or death. Vomiting, diarrhoea, stomach pain or drowsiness hours after eating wild mushrooms need urgent medical help.
Bad trips, panic and accidents
A bad trip can bring frightening hallucinations, paranoia and panic. Australia's National Drug and Alcohol Research Centre (NDARC) says deaths are rare, and that most are due to injuries such as falls and road accidents while people are confused or terrified. Never drive after taking them, and do not leave someone who is panicking alone.
The heart
Experts quoted by The Sun warn that repeated or high doses have been linked to heart rates of 150 to 160 beats a minute. The risk is greater for people with high blood pressure, heart disease or seizure disorders, and when mushrooms are mixed with cocaine, ecstasy or amphetamines such as syabu.
Mixing with other drugs and medicines
The Alcohol and Drug Foundation says mixing magic mushrooms with ice, speed or ecstasy makes a bad trip and panic more likely. NDARC warns that taking them alongside some psychiatric medicines can cause a mental health condition to relapse or get worse.
If someone collapses, has a fit, stops breathing normally or cannot be calmed, call 999 and tell the crew what they took.
Magic mushrooms and mental health
This is where the most lasting harm can happen. FRANK says magic mushrooms can make existing mental health problems worse. NDARC says people with a personal or family history of mental illness are more vulnerable, and that psychotic symptoms lasting more than 24 hours are rare but have been reported.
Some people get flashbacks: brief visual distortions that come back weeks, months or even years later. When these keep happening and cause distress, doctors call it hallucinogen persisting perception disorder. Our guides to drug-induced psychosis, how drugs affect the brain and depression and addiction explain these links in more detail.
Warning signs that need a doctor soon:
- hearing voices or believing things others cannot see, days after use
- severe anxiety, panic attacks or feeling unreal that will not settle
- flashbacks that keep coming back
- low mood, hopelessness or thoughts of self-harm
If someone is thinking about suicide, call 999 in an emergency, the HEAL line on 15555, or Befrienders.
Are magic mushrooms addictive?
Not usually in the physical sense. The Alcohol and Drug Foundation says they do not appear to cause physical dependence, and stopping brings few withdrawal effects apart from tiredness or mild psychological effects. Tolerance builds quickly, so the same amount soon has less effect.
That does not mean use is always harmless. NDARC notes a recognised hallucinogen dependence syndrome. In practice, mushrooms are often one part of a wider pattern: weekend use alongside alcohol, ecstasy, ketamine or synthetic drugs that are addictive. Signs that drug use has become a problem include:
- using more often than planned, or needing it to cope with feelings
- taking risks while high, or needing more to get the same effect
- carrying on despite panic, paranoia or flashbacks
- money problems, missed work or pulling away from family
- using several drugs together
Our guide to the signs of drug use covers what families can look for.
Psilocybin therapy: not the same thing
You may have read that psilocybin is being studied for depression. NDARC says Australia has allowed specialist psychiatrists to prescribe psilocybin in psychedelic-assisted psychotherapy for treatment-resistant depression since July 2023, and trials are still going on. That treatment uses a measured, pure medicine with screening and support from a medical team.
It is not the same as wild or street mushrooms, whose strength and contents are unknown, and it is not approved in Malaysia. Using mushrooms to treat your own depression or anxiety carries all the risks on this page.
Magic mushrooms and the law in Malaysia
Possessing or selling psilocybin is a serious offence under the Dangerous Drugs Act 1952. Bukit Aman police have said a urine test after taking mushroom drugs will come back positive. Our guides to drug laws in Malaysia and how long drugs stay in your system explain penalties and testing.
Asking for help is treated differently from being caught. Since the amended Act 283, adults can go to AADK directly for voluntary treatment, without a court process. Bernama reported in October 2026 that about 232 people a month now do this, and that voluntary clients do not get a criminal record. Our guide to voluntary drug rehab in Malaysia explains how it works.[10][8]
Getting help to stop
There is no medicine for stopping magic mushrooms, and most people do not need a medical detox for mushrooms alone. What helps is:
- a medical and mental health check, especially if there are flashbacks, paranoia or low mood
- honest talk about every drug used, because alcohol, sleeping pills and some other drugs do need medical help to stop safely
- talking therapy to understand why the person uses and to plan for weekends, parties and the friends linked to it
- treatment for anxiety, depression or psychosis at the same time, which our dual diagnosis treatment page explains
- family support, and a plan for the months after

Common questions
How long do magic mushrooms last?
Usually about four to six hours, starting around 30 minutes after eating them. Tiredness and low mood can last into the next day, and flashbacks can happen much later.
Can you overdose on magic mushrooms?
Life-threatening effects from psilocybin alone are uncommon, but large amounts can cause severe panic, psychosis, a racing heart and seizures. The bigger dangers are poisonous look-alike mushrooms, accidents and mixing with other drugs.
Are magic mushrooms legal in Malaysia?
No. Possessing or selling psilocybin is an offence under the Dangerous Drugs Act 1952, and medical psilocybin is not approved here.
Do magic mushrooms show up on a drug test?
Experts say they are not part of routine drug screening in Malaysia, but police have said urine tests after mushroom drugs can be positive, and mushroom products often contain other drugs that are tested for.
Is "Magic Mushroom" vape the same as mushrooms?
Not necessarily. When USM's National Poison Centre tested one vape line sold under that name, it found synthetic drugs and no psilocybin.
Where to get help
If mushrooms, or the drugs that come with them, are causing problems, help is there. AADK's voluntary route is free. A private drug rehabilitation centre in Malaysia offers a residential stay away from everyday triggers, and our page on choosing an addiction rehab centre in Malaysia explains what to look for.
