Medical Cannabis in Thailand: 2026 Supply Guide
As of 2026, Thailand regulates cannabis as medical-only (in force since June 2025): patients access it through licensed clinics and prescriptions, and businesses buy only with a license. On the supply side, quality rests on GACP: certified cultivation with documented traceability and a COA per batch. Here is how the supply chain works and what buyers should check.
The 2026 rules in brief
Cannabis in Thailand is a medical product: sales run through licensed businesses, and patients are served by licensed clinics. Rules have changed several times since 2022 and continue to evolve – verify current requirements with your counsel before acting.
How the supply chain works
GACP-certified farms grow and document the plant; licensed distributors, clinics and manufacturers then handle patients and finished products. Wholesale sits between the two: farms supply licensed buyers with tested, traceable flower and material – each batch with a third-party Certificate of Analysis (COA) – and those buyers serve their markets under their own licenses.
What to check before sourcing
- GACP certification (Thai and/or EU-GACP) – see what GACP-certified cannabis means.
- Third-party COA per batch – ask for a recent sample COA.
- Indoor vs greenhouse – climate-controlled rooms give batch-to-batch consistency.
- Traceability – seed-to-shipment records.
- Capacity – can the farm support recurring volumes, not one-off lots?
Where Solar Farm Thailand fits
Solar Farm Thailand is a Thai GACP certified (MOPH/DTAM) farm in Pathum Thani – 22 flowering rooms across 5,800 m², ~400 kg/month, a third-party COA on every batch and an in-house HPLC lab in commissioning. Licensed buyers can start at our cannabis wholesale hub, see the 2026 price guide, or read the GACP supplier overview. Near the capital? See our cannabis farm near Bangkok.
Verifying the license, the GACP certificate and the COA
Start with the cultivation license, not the sales deck. Check that the licensee name, site address and license period match the contracting entity and the facility you will visit; a license held by another company, or for another address, does not cover the flower you are buying. Expect the supplier to ask for your own import or wholesale license in return.
A GACP certificate is site-specific: it names the certified location, the scope of activities, the certifying body and a validity period. Confirm the address matches the license and the certificate is current, then verify it with the issuer rather than trusting the PDF. Thai GACP sits under MOPH/DTAM; for EU-GACP, ask which certification body issued it and confirm with that body.
A compliant COA comes from an independent laboratory, not the farm, and carries a lot number that matches the packaging. It should state sampling and analysis dates, the laboratory’s identity and accreditation, the method used, and results against stated limits for cannabinoid content, microbial load, heavy-metal levels and pesticide residues.
Chain of custody and the red flags to watch for
Chain-of-custody records should let you follow one lot from propagation through the flowering room, harvest, drying, trimming, packaging and dispatch, with the same batch identifier on the cultivation log, the COA, the packing list and the export paperwork. Ask for a sample lot file before contracting. Solar Farm Thailand provides export documentation and per-batch certificates of analysis to licensed buyers to support their import and QA process.
Warning signs that should pause a deal until resolved:
- Certificates supplied as screenshots, or with the site address or validity dates cropped out
- A COA generated in-house, or lot numbers that differ between the cultivation log, the COA and the packaging
- Reluctance to allow a site visit or a live video walk-through of the rooms named on the certificate
- No request for your license before volumes are discussed
Frequently asked questions
Is cannabis legal in Thailand?
It is regulated as medical-only (since June 2025) – access runs through licensed clinics and licensed businesses; rules change, so verify current requirements.
Who can buy medical cannabis wholesale in Thailand?
Licensed buyers only – hospitals, pharmacies, dispensaries, manufacturers and qualified export buyers, after license verification.
What makes supply “medical-grade”?
“medical-grade” here is a supply-chain descriptor, not a medical claim: flower cultivated under GACP (Thai and/or EU-GACP) with documented traceability and a third-party COA per batch – the paperwork licensed medical buyers are required to check.
How do patients access medical cannabis?
Through licensed clinics and prescriptions – patient access is handled by clinics, not by wholesale farms.
