They were small, brightly colored and designed to look less threatening than the drug they contained. In Thailand, tablets of yaba—an illicit methamphetamine-based stimulant—were reported in colors such as pink, purple, orange and green, with sweet flavors used to mask their bitterness. In 2013, Thai authorities warned that producers were adapting the tablets in an effort to appeal to younger users. But the strange appearance of yaba was only the surface of a much larger story: a cheap, highly addictive stimulant produced across the Golden Triangle and spreading through Southeast Asia.
What Exactly Is Yaba?
The name itself sounds almost harmless. In Thailand, yaba translates roughly as “crazy medicine,” but the drug is a form of methamphetamine, usually made into tablets and commonly combined with caffeine.
Unlike the image of a conventional pharmaceutical pill, yaba has often been heavily branded. UNODC reports that tablets found in Southeast Asia have appeared with different logos and packaging, with markings such as “999” and “Y1” frequently documented in Thailand. Those markings can help authorities link tablets to different production groups, although they do not by themselves establish where every pill originated.
The drug is a powerful stimulant that affects the central nervous system. It can produce increased alertness and energy in the short term, but methamphetamine use can also lead to dependence and serious physical and psychological problems.
That basic combination—an inexpensive tablet, a stimulant effect and a highly developed illicit supply chain—helped yaba become deeply entrenched across the region.

Why Did The Pills Look Like Candy?
This was the detail that attracted international attention.
The Guardian reported in 2013 that yaba tablets were appearing in bright colors and sweet flavors such as chocolate and strawberry, apparently to make them easier to take and less obviously associated with a bitter drug. Thai treatment specialists quoted by the newspaper warned that producers were changing the product to appeal to specific groups and that authorities believed children were among the people being targeted.
That does not mean every brightly colored tablet was intended for a child, nor does it mean that children were the dominant users of yaba. The point was that the drug market was behaving like a commercial market: producers were adapting the product’s appearance and presentation in an attempt to broaden its appeal.
That is what made the story so disturbing. A substance with the pharmacological risks of methamphetamine was being presented in a form that could look surprisingly ordinary to someone who did not know what it was.
The colorful appearance also created an illusion of familiarity. Something that resembles candy can seem less dangerous than something that looks unmistakably like an illicit drug, even though the chemistry inside the tablet has not become any safer.
The Drug Came From A Much Bigger Industry
Yaba did not emerge as an isolated problem in Thailand.
Much of the region’s methamphetamine supply has been linked to the Golden Triangle, the mountainous border area where Myanmar, Laos and Thailand meet. For decades, the region has been associated with illicit drug production and trafficking, but synthetic drugs have become an increasingly important part of that trade.
UNODC’s more recent reports show just how large the market has become. Thailand seized more than 1.05 billion methamphetamine tablets in 2024, up from roughly 395 million in 2019. The figures measure seizures rather than actual production or consumption, but they illustrate the enormous scale confronting authorities.
The tablets are also only one part of the market. Crystalline methamphetamine, commonly known as “ice,” is another major form of the drug and is generally much more potent than the tablet form.
The result is a regional synthetic-drug economy that can adapt quickly. Production can move, packaging can change and trafficking routes can shift when authorities disrupt one part of the network.
Why Yaba Became So Difficult To Control
For governments, the problem is not simply finding illegal drugs. It is disrupting a supply chain that can stretch across difficult terrain and multiple borders.
The Golden Triangle includes remote, forested areas where illicit laboratories can be difficult to locate. UNODC has documented how methamphetamine production in the region has evolved alongside changes in trafficking routes, branding and packaging.
At the street level, yaba has another advantage for traffickers: it can be distributed as a compact tablet rather than a bulky shipment of plant material. That makes it easier to conceal and move, while established demand provides an incentive for production to continue.
The drug has also been associated with very different groups of users. Earlier reporting described people using it to stay awake for long hours, while treatment specialists have warned about dependence and serious psychiatric effects associated with chronic use.
That combination of accessibility, portability and addiction makes yaba much harder to eliminate than a single police raid might suggest.
What Happens Inside The Body?
Methamphetamine is a stimulant, meaning it sharply increases activity in the brain and nervous system. Users may initially experience greater alertness, energy and reduced appetite, but the effects can come with serious risks.
The problem is not simply what happens during the period of stimulation. Repeated use can produce dependence, and heavy or chronic use has been associated with anxiety, hallucinations and psychosis. UNODC has also warned that methamphetamine use can have severe health consequences, including death.
The crash that follows prolonged stimulation can be very different from the energized state that initially attracts some users. Fatigue, depressed mood and disrupted sleep can create a cycle in which the person wants to use the drug again to escape the effects of coming down.
That cycle is one reason a tablet that looks deceptively simple can become such a serious public-health problem.
The Children’s Story Was Part Of A Larger Warning
The 2013 Guardian report focused heavily on fears that yaba manufacturers were deliberately trying to lure children through sweeter flavors, bright colors and social media. Thai officials were concerned that changing the presentation of the drug could lower the psychological barrier to experimentation among young people.
More than a decade later, the broader synthetic-drug problem is still significant. UNODC’s regional reporting shows enormous methamphetamine seizures in Thailand and continued production associated with the Golden Triangle.
But the most useful lesson from the original story is not simply that someone made drugs look like candy.
It is that illicit drug markets can behave like sophisticated consumer markets. When producers believe a different color, package, flavor or presentation might attract new customers, the product can change.
The danger is hidden behind the appearance. A colorful tablet is still a methamphetamine tablet. A sweet coating does not make the underlying drug mild, safe or suitable for a younger user.
A Tablet Designed To Hide What It Was
Yaba became notorious not because it looked frightening, but because it often did not.
The brightly colored tablets described in Thailand were a reminder that the appearance of a product tells you almost nothing about its pharmacological risk. Behind the candy-like presentation was methamphetamine, a powerful stimulant associated with dependence and serious health consequences.
The story also reveals something larger about the modern drug trade. The Golden Triangle is no longer defined only by the older image of opium production; synthetic drugs have become a huge part of the regional illicit economy, with tablet seizures reaching more than a billion in Thailand in 2024.
What looked like candy was actually a sign of something much more sophisticated: a drug market willing to change its appearance to reach new users.
And that may be the most unsettling part of the story. The danger was never in the color of the pill. It was in how effectively the appearance could make people forget what was inside.
Yaba is a tablet form of methamphetamine that became deeply established across Thailand and neighboring parts of Southeast Asia. The drug attracted international attention when reports described colorful tablets with sweet flavors, while Thai authorities warned that producers were adapting their product in an effort to appeal to younger users. The candy-like appearance did not make the drug safer; methamphetamine can cause dependence and serious physical and psychological harm. Behind the tablets is an enormous regional supply chain linked heavily to the Golden Triangle, reflected in Thailand’s seizure of more than 1.05 billion methamphetamine tablets in 2024. The story of yaba is ultimately about more than a strange-looking pill—it is about how an illicit market can change its appearance without changing the danger inside.
