Recent local news about Koh Chang's cannabis shops is scarce. In March 2026 police seized more than 40 kg of cannabis bricks that washed up on Hat Sai Khao (White Sand Beach); investigators suspect a lost or abandoned maritime trafficking shipment.
Always confirm a shop's licence on the government's MC-GIS map before you visit. Listings are editorial and free.
Open MC-GIS mapWe could not confirm any listing here on the business's own website. Most details come from directories, and some shops may have closed since the June 2025 rules, so call ahead.
Mueang Trat (mainland, nearest listed clinic)
Issues PT33 on site

A small chain with three west-coast branches sharing one phone number. Its directory listing says flower requires a PT33 and staff can refer customers to a clinic on the island.

PT33 on site: not stated
