Medical-Only: What the New Thai Cannabis Framework Actually Allows
Thailand's medical-only cannabis framework allows legal use with a valid Thai prescription, purchased from a licensed dispensary that has medical supervision on-site. It permits low-THC CBD products more freely, and it allows prescribed patients to possess limited amounts. What it does not allow is recreational sale, purchase without a prescription, or public consumption.
What is allowed
Under the framework, a patient consults a licensed Thai practitioner, receives a PT33 prescription valid up to 30 days if a qualifying condition is identified, and buys from a licensed dispensary. Prescribed patients may carry limited quantities, reportedly up to 30 grams. CBD products under 0.2 percent THC are treated as health products and are more accessible. These are the legal channels.
What is not allowed
Not allowed: buying cannabis flower without a prescription, recreational use, selling without a license and medical supervision, and consuming in public, which remains a nuisance offense. Extracts above 0.2 percent THC fall under stricter narcotics rules. Import and export are prohibited. The framework is permissive only within clearly drawn medical lines.
The compliance layer for businesses
For operators, the framework means a dispensary must be a medical outlet: licensed, medically supervised since January 2026, verifying prescriptions, and sourcing from certified growers. This is why so many shops closed, and why the ones that remain look more like clinics than the recreational stores of a few years ago. The framework is as much a business filter as a consumer rulebook.

Three findings from the 2026 edition, free.
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.
LikelyBuilt from 850+ dispensary visits across Thailand, 100+ dispensary owner and operator interviews, 30+ farm owner and operator interviews, and 400+ customer interviews across 40 nationalities. 101 pages. 23 chapters. Every chapter sourced, every figure confidence-tagged.
