Thailand’s Ministry of Public Health has confirmed it will push the country’s remaining cannabis dispensaries into a regulated medical clinic model, ending the open retail framework that has defined the industry since decriminalization in 2022. Public Health Minister Pattana Phromphat announced the policy on April 1, formalizing a transition that has been building through ministerial regulations over the past year.
Operators have a three-year window to convert their businesses into licensed medical facilities under the Medical Facilities Act.
The deadline is not a single cutoff but a rolling one, tied to each operator’s existing license renewal date. With around 40% of permits expiring each year, the industry will reshape itself in waves rather than overnight.
What the New Framework Requires
Under the new model, cannabis can no longer be sold through standalone dispensaries. Sales must take place through a licensed medical clinic, a modern pharmacy, or a traditional medicine pharmacy, each governed by a different statute depending on the establishment type.
Every facility must have an on-site licensed practitioner authorized to issue cannabis prescriptions, and must meet clinical standards for storage, hygiene, odor control, and record-keeping.
On top of the underlying healthcare license, each establishment also needs a separate license to sell controlled herbs, issued by the Department of Thai Traditional and Alternative Medicine and renewable every three years.
The prescription requirement is what fundamentally changes the customer relationship. Cannabis flowers can only be dispensed to patients who present a valid prescription, and only seven categories of professionals are authorized to issue them:
- Medical doctors
- Dentists
- Pharmacists
- Thai traditional medicine practitioners
- Applied Thai traditional medicine practitioners
- Traditional Chinese medicine practitioners
- Folk healers
Each prescription is capped at a 30-day supply, and walk-in retail (even with informal medical framing) is no longer permitted.
The supply side is similarly tightened. All cannabis flowers sold or exported must come from farms certified under Good Agricultural and Collection Practices (GACP), and recreational sales, advertising, and public consumption are now banned outright. Operators that fail to comply face license suspension or revocation, criminal penalties of up to one year’s imprisonment, and fines of up to THB 20,000.
A Market That Has Already Contracted Sharply
The new policy formalizes a contraction that was already well underway before the April announcement.
The number of registered cannabis outlets has fallen from a peak of around 18,000 in 2023 to roughly 11,000 today, and officials estimate that only about 3,000 of those remaining outlets are realistic candidates for conversion to the clinic model.
The rest are expected to close rather than absorb the cost and operational complexity of becoming medical facilities, which means the industry’s actual footprint will likely shrink to less than a fifth of its peak by the end of the three-year transition.
To support enforcement, the Ministry of Public Health is rolling out a verification system that includes shopfront stickers showing each outlet’s license status and expiry date, alongside a national database of authorized facilities.
The intent is to make it easier for officials to identify non-compliant operators, and help legitimate patients find providers who can lawfully serve them.
How Thailand Got Here
The political backdrop matters here, because the current rollback comes from the same political force that originally opened the industry.
Thailand became the first Asian country to decriminalize cannabis in 2022, when then Public Health Minister Anutin Charnvirakul of the Bhumjaithai Party removed cannabis from the narcotics list.
The stated intent at the time was to enable medical use, but the absence of an actual Cannabis Act left a regulatory vacuum that was quickly filled by retail entrepreneurs, particularly in tourist destinations like Bangkok, Phuket, and Pattaya.
That vacuum became politically untenable.
In June 2025, after Bhumjaithai withdrew from the ruling coalition, the Pheu Thai-led government introduced regulations classifying cannabis flower as a controlled herb and restricting sales to prescription-only.
A more comprehensive medical framework followed in December 2025, ending the consumer-retail model and requiring all license renewals to meet full medical clinic standards.
The April 2026 announcement now comes from a new Bhumjaithai-led government with Anutin serving as Prime Minister, finalizing the wind-down of the very industry his earlier policy created.
Even with this latest move, Thailand still does not have a unified Cannabis Act. The current framework relies on ministerial directives, controlled-herb notifications, and sector-specific laws stitched together without a single governing statute.
What This Means for Operators and Investors
For existing operators, the dispensary business model is effectively closed. The choice over the next three years is binary: convert into a licensed medical facility under the new framework, or exit the market when your current license expires. There is no middle path.
Operators that intend to convert should begin planning well before their renewal date, since the licensing requirements involve healthcare credentialing, facility upgrades, and supply chain changes that take time to put in place.
The opportunities that remain are concentrated upstream and downstream of retail rather than at the storefront level. The government is actively encouraging investment in:
- GACP-certified cultivation for domestic supply and export
- Extraction and processing for pharmaceutical and cosmetic applications
- Clinical research partnerships with Thai medical institutions
- Wellness and medical tourism built around licensed clinical settings
Tourist-facing cannabis businesses, on the other hand, no longer have a viable regulatory path forward.
The broader caution for anyone evaluating this market is that the regulatory environment remains unstable. Until the Cannabis & Hemp Act is passed by parliament, the framework can shift again through ministerial directives, as it has multiple times since 2022.
Operators and investors should plan for further changes rather than assume the current rules will hold.
