What Cannabis Products Can You Still Buy Legally in Thailand?
What you can still legally buy in Thailand depends on whether you have a prescription. With a valid Thai prescription, you can buy cannabis flower from a licensed, medically supervised dispensary. Without a prescription, your legal options narrow to low-THC CBD products under 0.2 percent THC and a small number of Thai FDA-approved products. High-THC flower without a prescription is not a legal purchase.
With a prescription
A PT33 prescription unlocks the main product: cannabis flower, bought from a licensed dispensary that verifies the prescription and has medical supervision. This is the legal route for the high-THC products most people mean by cannabis. Everything about that purchase, from the shop's license to the prescription check, is what makes it compliant.
Without a prescription
Without a prescription, the accessible legal category is low-THC products. CBD items containing less than 0.2 percent THC are treated as health products and are widely available from legitimate retailers. In addition, a small number of cannabis products have obtained Thai FDA approval, such as certain approved edibles, which can be sold through approved channels. These are the narrow legal options for someone without a prescription.
What is not legal to buy
Not legal without a prescription: high-THC cannabis flower and high-THC products generally. Extracts above 0.2 percent THC fall under stricter narcotics rules. And regardless of product, buying from an unlicensed source or online, where prohibited, is not compliant. The legal market is real but narrow, and the boundaries are the THC content and the licensing.

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.
