How Thailand went from cannabis free-for-all to medical-only

Four years ago, Thailand became the first country in Asia to decriminalise cannabis. By 2023, dispensaries had opened across Bangkok from Sukhumvit to Silom, and the country's cannabis scene had become part of the tourist experience for many visitors.

That market no longer exists in its original form. What replaced it is a medical framework built through a series of ministerial orders that accelerated through 2025 and 2026. The change was less a reversal than a course correction, moving from an unregulated consumer market to a controlled medical one.

How the regulatory shift happened

In June 2022, cannabis was removed from Thailand's narcotics code, triggering rapid dispensary growth nationwide. By late 2023, the Ministry of Public Health was already signalling that recreational use would be restricted, and a dedicated Cannabis-Hemp Act began moving through the legislative process.

The key regulatory milestones from that point:

• June 2025: Cannabis flower reclassified as a controlled herb, ending the open market that had operated since 2022

• September 2025: Medical cannabis formally restricted to five approved conditions, with prescriptions required for all flower purchases

• January 2026: Mandatory on-site licensed practitioners required at all operating dispensaries

• April 2026: Premises restricted to medical facilities, pharmacies, herbal product retailers, and the workplaces of traditional healers

The impact on the industry was significant. As of late December 2025, Thailand had 18,433 cannabis-related establishments on record. During 2025, licences for 8,636 shops expired, but only 1,339 applied for renewal, roughly 15.5%. More than 7,000 shops closed without renewing.

What is currently legal?

Cannabis is legal in Thailand, but only within a medical framework. Medical cannabis is accessible with a valid Phor Thor 33 (PT33) prescription, issued by a licensed medical practitioner, valid for approximately 30 days, and covering a specific quantity for a specific qualifying condition. 

Possession without a valid prescription is not permitted.

CBD products remain available without a prescription, provided THC content stays below the regulated threshold.

What is no longer permitted includes recreational sale, public consumption, online sales, vending machine

dispensing, and sales through channels that do not involve a licensed practitioner. Fines for public consumption can reach 25,000 baht. 

Bringing cannabis into Thailand from abroad, including from countries where it is legally prescribed, is treated as drug trafficking under Thai law. Foreign prescriptions carry no validity in Thailand.

How compliant dispensaries operate

The shops that have continued operating are those that invested in compliance before it became mandatory. The central requirement is a licensed practitioner physically present during all operating hours, able to conduct consultations and issue PT33 prescriptions on site. This is an operational requirement, not a paperwork formality.

Sourcing has also changed significantly. All commercial cannabis flower must originate from GACP-certified farms, and dispensaries are required to maintain documented records covering supply chains, prescription issuance, and dispensing. These records are subject to inspection.

LV Cannabis, operating across Bangkok and Phuket, has structured its model around this compliance framework. The broader industry picture is one of ongoing consolidation, with a further wave of licence expirations expected through 2026 and 2027. 

What separates the shops that remain from those that closed is not primarily pricing or location, but the capacity to operate within a medical framework that requires meaningful investment in staffing, sourcing, and infrastructure.

What does the process look like in practice?

A visit to a compliant dispensary now resembles a medical consultation. A licensed practitioner will assess whether cannabis is appropriate for the visitor's health concerns and, if so, issue a prescription specifying the product, quantity, and duration. A valid passport is required. Most compliant dispensaries handle the entire process in a single visit.

For anyone wondering whether weed is still legal in Bangkok, the answer is yes, but only within the same medical framework that applies across Thailand.

When choosing a dispensary, look for a licensed practitioner on site, a PT33 prescription issued before any cannabis is dispensed, and GACP compliance documentation. Any shop dispensing cannabis without a prescription check is operating outside the current legal framework.

For residents on long-stay visas, the process is the same as for tourists and Thai nationals. The PT33 framework makes no distinction based on residency status.

What comes next?

The underlying Cannabis Act continues moving through the Thai legislative process, and the current medical-only framework has cross-party support following the 2026 elections. The specific requirements around facility types, qualifying conditions, and licensing categories are still being refined, so the framework should be treated as directionally stable rather than fully settled.

Thailand's online cannabis shop tracker, launched in April 2026, allows anyone to verify whether a dispensary is currently licensed and operating legally before visiting.
