Siam Green Cannabis Co
663 Sukhumvit Rd, Khwaeng Khlong Tan Nuea, Watthana, Bangkok 10110
Lead with a budtender consultation. Siam Green built the chain around English-speaking staff and education rather than counter-and-go retail, and the brand carries Local Boys, Auracl, and Loy Gummies among the curated lineup. Walk in with your goal, sleep or social or focus, and let the budtender route the recommendation through the curated jars.
The Sukhumvit 663 branch is the one most travelers find first. You walk in off Sukhumvit Road between Phrom Phong BTS exit and the Emporium-EmQuartier corridor, and the room opens onto a counter with humidity-controlled jars and a coworking lounge at the back.
The operation runs across five locations. The Phrom Phong flagship opened January 2023, Nana on Sukhumvit 10-12 followed in 2024 near Asoke BTS and Sukhumvit MRT, and Chinatown on Maha Chai Road sits opposite Jay Fai. Silom is the newest Bangkok branch at Sala Daeng BTS exit 4, two minutes from Patpong. Chaweng on Koh Samui completes the chain. Patrick owns the company. The brand opened in 2022 and has grown into the five-location footprint since.
The model is consultation-led rather than self-serve. In-shop prescription handling is part of the process for any cannabis purchase, English-speaking budtenders walk you through strain selection, and tourists are accepted with a passport. The product range covers flower, edibles, accessories, and the curated brand list runs Local Boys, Auracl, Loy Gummies, and additional house-vetted suppliers. Typical price range across the locations sits between 450 and 900 baht.
The Sukhumvit room has a coworking space at the back, which extends the visit beyond the transaction. Travelers can browse, consult, and stay rather than buy and leave.
Bring your passport. Thai cannabis regulation requires ID for purchase, and the chain runs the prescription paperwork at the counter, so the document is the prerequisite before any consultation begins.
