Our Story

High Siam is a proudly Thai–owned cannabis brand built by a group of brothers with deep roots in the local stoner culture. What began as a passion project has grown into a network of cannabis shops across some of Thailand's most iconic destinations.

Each store is a reflection of the High Siam ethos: local, laid–back, and laser–focused on quality. We believe that weed is about more than just the product. It's about the environment you enjoy it in, the people around you, and the energy of the moment.

Founded by locals, for everyone
