Three years after Thailand became the first Asian nation to decriminalize cannabis, its groundbreaking policy may collapse under political turmoil. The recent exit of the pro-cannabis Bhumjaithai Party from the ruling coalition, has left prohibitionists in control.
Political instability threatens everything
Thailand's Parliament faces potential dissolution amid calls for Prime Minister Paetongtarn's removal following a leaked phone call in which she called former Cambodian Prime Minister Hun Sen "Uncle" and promised to "take care" of his concerns, even referring to a prominent Thai army commander as being part of "the opposite side." In a country with 12 successful coups and 31 prime ministers since 1932, political upheaval isn't speculation—it's pattern. Whether through parliamentary maneuvering or military intervention, the disruption will derail cannabis reform along with everything else.
The coalition that couldn't hold
After the 2023 election, the anti-cannabis Move Forward Party won the most votes but couldn't form a government. The second-place Pheu Thai Party (also anti-cannabis reform) then made a fateful choice: instead of aligning with ideologically similar Move Forward, it formed a coalition with conservative parties—including Bhumjaithai, the architects of decriminalization.
This marriage of convenience was doomed from the start. Pheu Thai promised to restrict cannabis to medical use only, while Bhumjaithai and its leader Anutin Charnvirakul refused to abandon his signature achievement. By mid-2024, the coalition gave up trying to reverse course, but the cannabis divide added to the political fault line that was breaking the government apart.
Bhumjaithai's exit opens door to adult-use prohibition
With Bhumjaithai now out of government, the pro-regulation movement has lost its strongest voice in government. This clears the path for Pheu Thai (who's coalition now has only a razor thin margin) to realign with Move Forward (now the opposition People's Party)—a party similarly hostile to cannabis liberalization. What began as an innovative public health and agricultural policy now faces potential reversal rather than regulation. In fact, just days after Bhumjaithai exited the coalition, the Health Ministry began moving forward with recriminalizing cannabis. The Health Ministry issued notices that medical prescriptions will soon be required to access cannabis while the government works on a more comprehensive recriminalization policy. Additionally, last week the Office of the Narcotics Control Board "deployed over 100 officers in a coordinated sweep of 20 cannabis shops across Bangkok." Even though the minister of health stressed that the sweep had no connection to the Bhumjaithai Party exiting the ruling coalition, such a move cannot be overlooked as a sign of things to come.
Legal limbo hurts everyone
Cannabis currently exists in a regulatory vacuum that serves no one well (prohibitionists and proponents alike). While no longer a scheduled narcotic, there's no national framework governing cultivation, distribution, or sales or cannabis in Thailand. Unregulated and untested products are the standard, not the exception. Thousands of dispensaries operate without clear legal guidelines, creating compliance nightmares for investors and confusion for consumers.
The longer this "wild west" continues, the more ammunition it provides to prohibition advocates. Every incident involving unsafe products, youth access, or public disorder becomes evidence that decriminalization was a mistake. Cannabis reform proponents are losing the narrative battle by default—the absence of regulation creates the very problems that opponents will use to justify re-criminalization. Without quality controls, age restrictions, and proper oversight, Thai society bears the costs while prohibition forces collect the political benefits.
Unfortunately, without Bhumjaithai's voice in government, any legal certainly will lean towards prohibition rather than regulation.
Medical cannabis potential remains untapped
Thailand could dominate global medical cannabis markets given its agricultural advantages and growing expertise. But international buyers demand legal consistency, standardized quality, and trade compliance—none of which exist under the current system. Without formal national regulation, Thai producers remain largely locked out of lucrative export opportunities. With Pheu Thai focusing on medical cannabis, clarity here could be a bright spot in a future prohibitive regulatory framework.
No clear path forward
Thai political instability makes positive cannabis reform unlikely in the near term. If new laws do emerge quickly, it appears that they'll restrict rather than regulate. We are already seeing policy announcements from the Ministry of Health verifying this move towards restriction.
A dissolved Parliament would restart the entire political process—new elections, new coalitions, new priorities. Further electoral gains from Pheu Thai or Move Forward/People's Party could be even more disastrous for cannabis.
The bottom line
Thailand's cannabis experiment is collapsing under political chaos. In the Bhumjaithai Party's absence, the prohibitionist leadership is already moving to scale back access in favor of a restrictive medical-only program. Unless the political winds shift and Bhumjaithai regains influence within the government, Thailand's wild-west experiment appears headed for extinction.
Hopefully, this cautionary tale teaches the global cannabis community a critical lesson: decriminalization without regulation may earn applause in the short term, but it can create chaos that prohibition advocates exploit to justify reversal. We warned of this in 2022, when we explained what the Thai reforms actually meant, and wrote, "it seems like the government may end up playing a game of catch up as the market's growth outpaces regulation."
When policy creates a regulatory vacuum instead of a structured framework, opponents don't need to manufacture problems—they simply point to the inevitable disorder and declare the experiment a failure. Thailand's unraveling reform efforts are a stark reminder that sustainable cannabis reform requires deliberate regulation, not just the absence of criminalization.
