BANGKOK — Just three years after making history as the first Asian nation to decriminalize cannabis, Thailand is poised to drastically reverse course, plunging its burgeoning industry into uncertainty. New regulations, set to take effect on Thursday, June 26, 2025, will fundamentally alter access to the plant, mandating a medical prescription for purchases and imposing strict controls on supply.
The policy pivot marks a significant shift from the permissive environment that emerged following decriminalization in June 2022. That landmark decision spurred the rapid growth of an industry now estimated to comprise between 10,000 and 18,000 dispensaries across the country, many of which have opened their doors since 2022.
Sweeping Regulatory Changes Ahead
Under the forthcoming rules, acquiring cannabis will no longer be a simple retail transaction. Consumers will be required to obtain a prescription from a licensed medical professional, effectively restricting access to individuals with recognized medical conditions. Furthermore, the regulations will cap individual purchases at a 30-day supply per customer, introducing a quantity control measure previously absent in the largely unregulated market.
In addition to controlling consumer access, the new framework imposes stringent requirements on the supply chain. Dispensaries will be permitted to sell only cannabis sourced from farms holding the government’s “Good Agricultural and Collection Practices” (GACP) certifications. This mandate aims to elevate quality and safety standards but also centralizes control over production, potentially marginalizing smaller cultivators or those unable to secure the necessary certifications.
Political Drivers and Timing
The move aligns with a key pledge made by Prime Minister Paetongtarn Shinawatra’s ruling Pheu Thai Party. The party campaigned on a platform that included strengthening the country’s drug policy and restricting cannabis use primarily to medical purposes, a stark contrast to the de facto recreational use that flourished under decriminalization.
The timing of the decision is also notable. It follows the departure of the pro-cannabis Bhumjaithai Party from the governing coalition just days prior. Bhumjaithai, previously the second-largest bloc in the government, had been a key architect and proponent of the 2022 decriminalization, advocating for broader access and economic opportunities within the industry. Their exit appears to have cleared the path for Pheu Thai to implement its more restrictive agenda.
Industry Backlash and Criticism
Predictably, the impending regulations have caused considerable disruption within the Thai cannabis industry. Dispensary owners, cultivators, and related businesses face the daunting prospect of adapting their operations, potentially requiring significant investment in compliance or facing closure.
The policy shift has also drawn sharp criticism from pro-cannabis activists and industry stakeholders. Rattapon Sanrak, the owner of Highland Cafe in Bangkok and a prominent voice in the pro-cannabis movement, has publicly condemned the measures.
Sanrak described the new rules as “political revenge,” suggesting the stringent restrictions are more a consequence of political maneuvering than a genuine concern for public health or drug policy efficacy. He further warned that the measures would negatively impact the public, highlighting potential job losses, economic disruption, and a return to the black market for cannabis access.
Facing an Uncertain Future
The transition back to a strictly medical model presents significant challenges. The thousands of dispensaries that have thrived in the liberalized environment must now navigate a complex regulatory landscape requiring medical affiliations and certified supply chains. Many fear the new rules could decimate an industry that quickly became a significant contributor to tourism and local economies.
As Thailand prepares for the regulations to take effect on June 26, 2025, the future of cannabis in the country remains highly uncertain. The rapid reversal highlights the volatile political landscape surrounding the plant and serves as a cautionary tale for other nations considering similar liberalization efforts.
