BANGKOK: It was billed as a savior to Thailand’s post-pandemic slump, but the runaway cannabis industry has instead sparked a deep domestic backlash that could see the plant criminalised once again after next month’s election.
Thailand became the first country in Asia to decriminalise cannabis in 2022. The move was widely supported, with people told the country would emerge as a regional hub for medical cannabis that would expand the health tourism sector and create a new cash crop for farmers.
But within months it was clear the policy had instead sparked a boom in recreational use that spread to children.
Thousands of shops selling ready-rolled spliffs and fruit-flavored gummies mushroomed across the country and the smell of cannabis on city streets became as ubiquitous as grilled pork.
Doctors warned of a spike in hospital admissions, tourism groups feared the loss of high-spending visitors, and foreign governments complained of a rise in drug smuggling.
Studies have also shown growing recreational use among schoolchildren, a major point of contention among many Thais.
"It got out of control and has had a huge negative impact, especially on children and young people under 25, whose brains are still developing,” said Yodsakorn Khunphakdee, coordinator of Youth Network Against Cannabis, which submitted a petition to the Public Health Ministry last year with 200,000 signatories urging decriminalisation to be overturned.
Although authorities say the policy was designed for medical use, the lack of clear regulations created a gray area. Dispensaries with flashy neon signs dish out products freely, even after new rules established last year mandated the need for prescriptions.
Patraporn Kinorn, a doctor specialising in child psychiatry and addiction treatment, said she’s seeing an increasing number of young patients addicted to cannabis. Youths are self-administering the plant to treat depression only to find their conditions worsen, she told a seminar about cannabis-induced illnesses in Bangkok earlier this month.
"The law may say that children are already protected, but the question is: is it enough?” she said.
A study by Thailand Development Research Institute, published in 2024, showed the number of people who used cannabis for recreational purposes rose nearly ten-fold from 1.2 million in 2020 to 11.1 million in 2022. Those who take the plant for medical reasons grew from 430,000 to just 540,000 during the same period.
Father of two Thapanawong Ladkaew, a 38-year-old businessman, said the normalisation of smoking cannabis worried him as a parent, describing flea markets that openly sell it and coffee shops with bongs on display in his small northeastern town.
"My kids were asking about this out of curiosity,” Thapanawong said, suggesting recreational use should be limited to tourism party hot spots like Pattaya. "I certainly don’t want my children to try cannabis.”
Ministry of Public Health hospitalisation data analyzed by Bundit Sornpaisarn, a staff scientist at the Institute for Mental Health Policy Research in Canada, show that monthly cannabis dependence cases rose sharply from an average of 162 in the year before decriminalisation to 447 the year after, and 837 the year after that.
Cannabis-induced psychosis jumped five-fold over the same timeframe.
As many began to question the costs to society, the tide of support changed: over two thirds of Thais polled in 2024 wanted the plant reclassified as a narcotic, according to the National Institute of Development Administration.
The budding industry says it’s been left high and dry by major political parties.
Noticeably silent about the issue on the campaign trail is the man who spearheaded decriminalisation - Prime Minister Anutin Charnvirakul.
Once hailed as the "Cannabis King,” he rose to political notoriety in the 2019 election for championing the drug for medical use and as a cash crop.
A deputy leader for his ruling Bhumjaithai Party told Bloomberg News that its cannabis policy had been "distorted heavily” and was never intended for recreational purposes. If the party returns to power after the Feb 8 vote, it would push for legislation to allow only for medical use without recriminalising it.
The reformist People’s Party and Pheu Thai Party, two other political parties leading in polls, however have indicated the plant would be back on the narcotics list - although the issue is not featured in their pledges.
"We’re deeply disappointed, because the party that unlocked cannabis and our only political ally has now gone down a different path from ours,” said cannabis advocate Prasitchai Nunual, whose hopes have risen and fallen with each new government coalition. "There seems to be no future for an equitable cannabis law.”
Now Prasitchai is running for parliament, hoping to gain support for tighter regulations, including for recreational use. Although his chances of driving the change in parliament are slim, it reflects the desperation rippling through the community of cannabis advocates and entrepreneurs.
Nuttanan Wichitaksorn, a visiting research advisor at Thailand Development Research Institute, said the policy yielded "no positive economic impact at all,” even though the industry had been tipped to be worth $1 billion dollars by 2025.
In a study for the institute in 2024, he found only 25% of 177 companies surveyed were profitable. The lack of a business case is another reason political parties are ignoring the issue during election season, he concluded.
"It's not a hot issue anymore. Now they see other things that are more exciting and get more votes,” he said.
The US pot industry has grown into a US$40 billion industry since California first legalized medicinal cannabis in 1996, with weed now legal in 24 states for recreational purposes and in 40 for medical use.
Porlnarong Panor, a home grower of premium-quality buds, says he may soon stop production at his small growing facility in Bangkok and close his dispensary because of the uncertainty.
After selling a Harley Davidson and pouring his savings into grow lights and a dispensary, he feels betrayed.
"The people who unlocked it didn’t think things through from the start. They’re the government now, and they still didn’t care,” said Porlnarong, referring to Anutin.
New rules that will soon require dispensaries to become licensed medical facilities and have a medical practitioner onsite are too costly for him to implement.
"They said everyone should be able to grow and sell, but now it’s not for everyone,” he said. "Only those with big capital and certified farms can survive.”
The government has said 7,000 out of 18,000 shops didn’t apply to renew their licenses at the end of 2025 as a result of the tougher rules.
But some businesses remain optimistic stricter regulations could elevate the industry by weeding out sub-standard stores. The owners of Shaggy Buds, a dispensary in one of capital’s busiest commercial districts, said they planned to build a new store for regulatory compliance.
"I don’t think 2026 is the beginning of the end for the industry,” said Nitikrist Attakrist, a co-owner. "It is actually an opportunity. If you could pass all the criteria, you would build a strong foundation for the future.” - Bloomberg
