The three numbers Thailand's government will not publish

Ask any Thai regulator how much cannabis the country grows, how much of it moves through the legal chain, or how much gets lab-tested along the way, and you will get silence. Not a vague answer. No answer at all. That absence is not an oversight, and every model that ignores it is guessing at scale while pretending to measure it.

No Thai authority publishes national cultivation area, production tonnage, or lab-testing throughput Certain. Not the Ministry of Public Health, not the FDA, not the Department of Thai Traditional and Alternative Medicine. There is no national register that adds up hectares under cultivation across the country's growers. There is no production census that totals tonnage from seed to sale. There is no aggregated figure for how much material actually passes through a lab before it reaches a shelf. Three separate load-bearing numbers, and three separate absences.

Why the gap exists

This is not a case of bad recordkeeping. It is the structural consequence of how Thailand built the framework. Cannabis flower was decontrolled fast, licensing was distributed across GACP-certified farms that now number 217 Certain and are growing at roughly ten a week, and enforcement capacity was never built to match the pace of issuance. Each farm, each dispensary, and each lab operates as an independent node reporting into a licensing system, not a production-statistics system. Licensing tells a regulator that an entity is permitted to operate. It does not tell anyone what that entity actually produced, sold, or tested in a given month.

Add to that the fact that cannabis flower now sits under Thai traditional-medicine law as a "controlled herb" requiring a PT 33 prescription, while extracts above 0.2% THC remain Category 5 narcotics under a separate legal regime entirely. Two different laws, two different enforcement bodies, neither one tasked with national output measurement. A regulator built to control access to a herb is not the same apparatus as a regulator built to count tonnage. Thailand built the first. It never built the second.

Why it matters more than the headline numbers

Every forecast in circulation, including the ones claiming Thailand reaches $7.1 billion, $9.18 billion, or $9.6 billion by 2030, has to make an assumption about supply somewhere in its model. Revenue does not exist independent of what gets grown, processed, and tested. When the underlying tonnage, area, and throughput are unknown, any revenue figure built on top of them is a number built on a number nobody actually has. It is guessing wearing the clothes of a forecast.

The triple absence also means nobody outside the industry can independently sanity-check claims made by any single operator, promoter, or forecast. If a producer says its facility processes a given volume, there is no national baseline to compare it against. If an analyst claims the legal grey-market split moved in a given direction, there is no throughput series to test it. The absence does not just create uncertainty about the size of the market. It removes the ability to verify anyone's story about it, ours included, which is why every figure we publish carries a confidence tag rather than a claim of certainty.

This is also why so much of the public commentary on Thailand's cannabis sector defaults to shop counts. Shop counts are visible, countable, and reported: roughly 18,433 at peak, about 7,297 closed by early 2026, leaving about 11,136 operating. Counting doors is easy. It is also the wrong unit. A shop count tells you nothing about how much product moves through those doors, what fraction of it was grown legally, or what fraction was ever tested. Substituting a countable proxy for an uncountable reality is how the sector's coverage ended up thinner than the industry itself.

How a field reconstruction fills it

Filling a gap that no authority tracks requires going around the absence rather than waiting for it to close. That means building the picture from the ground up: farm-by-farm visits to estimate area under cultivation, operator interviews to triangulate typical yields and processing volumes, and direct observation of how much product actually reaches testing before sale versus how much bypasses it entirely. None of that comes from a central register, because no central register exists. It comes from counting what is actually there.

The reconstructed national cultivation area, production tonnage, and lab-testing throughput are set out in full, scenario by scenario, in the report Guessing, as any estimate built without a government baseline must be . see the reconstruction in the report → Each figure is confidence-tagged rather than presented as fact, because a reconstruction is exactly that: the best obtainable estimate of a number the government itself does not have, not a substitute for one the government has simply declined to release.

How we know this

This reconstruction is built on direct fieldwork, not modeling from a distance: 850+ dispensaries visited across the country, including 650 in Bangkok, more than 100 owner and operator interviews spanning ten-plus nationalities, and over 30 farm operators walked through their own cultivation and processing. The team also completed Thailand's full legal cannabis licensing process first-hand, which is the only way to see exactly where the paperwork stops and the physical count never begins.
