Where Does the Cannabis in Thai Dispensaries Actually Come From?

The cannabis in Thai dispensaries comes from two very different places: a certified legal-channel supply from licensed growers, and a large volume of grey-market flower that never properly passed through the licensed system. Much of what sits on dispensary shelves, by many accounts a large share, originates outside the clean legal channel even though it is sold through legal shops. This gap between legal retail and grey supply is one of the market's defining features.

The legal channel

Certified growers, meeting the GACP standard, supply the legal medical channel. This is the compliant path: certified cultivation to licensed dispensary. But the certified base is limited relative to demand, which creates a supply gap that something has to fill.

The grey channel

That gap is filled by grey-market flower: product grown or moved outside the fully compliant system that nonetheless ends up sold through licensed dispensaries. A significant portion of dispensary flower reaches the shelf this way, which is why the legal retail market and the legal supply chain are not the same size. The dispensary can be legal while a large share of its flower had an irregular journey to get there.

Why it matters

This split matters enormously for anyone assessing the market. It means retail legality overstates supply-side legality, that certified supply is scarcer than dispensary shelves suggest, and that the true structure of the market is more complicated than a shop count implies. Quantifying that split is one of the harder and more valuable pieces of market intelligence.
