What Is the Politics Behind Thailand's Cannabis U-Turn?
Thailand's cannabis U-turn was as much political as it was about public health. The party that championed the 2022 decriminalization left the governing coalition in 2025, removing its political protection, and the successor government moved to a stricter medical-only framework rather than restoring the open market. Understanding the politics explains why the reversal happened and why it is unlikely to swing back soon.
The rise and the opening
The 2022 decriminalization was closely associated with a specific political party that made it a signature policy. For a few years, that political backing kept the market open and lightly enforced, even though a full recreational law was never actually passed. The permissive period rested on political will as much as on legislation.
The coalition shift
When the political configuration changed in 2025 and the party most associated with cannabis left the governing coalition, the protection went with it. The reclassification to medical-only followed. Notably, even the original architect of decriminalization, who later became Prime Minister, did not reverse the medical-only move, which signals a settled direction rather than a temporary swing.
Why the politics point one way
The political incentives now favor clarity and control over a return to the open market. That does not rule out further tightening, including the stated intention to reclassify cannabis as a narcotic, but it makes a return to 2023-style permissiveness unlikely. For anyone assessing regulatory risk, the political read matters as much as the legal text.
Political change removed the protection the open market relied on.
No; it operated in a permissive grey zone without a full law.
No, it kept and tightened it.
Unlikely soon; the politics favor control.

Of 8,636 expired dispensary licences, 1,339 renewed. The rest did not bother. That is not a market collapsing. That is a market taking out its own trash.
CertainFewer shops, higher revenue each. The closures removed storefronts, not revenue, because the shops that closed were earning almost nothing. Every desk model read the count and stopped.
LikelyA small minority of shops earn a disproportionate share of all revenue. The bottom half earns a fraction of it. Nobody else has measured this.
