The neighborhood
Our Silom shop sits between Sala Daeng BTS and Silom Complex, a few minutes' walk from each. Daytime customers come from the office towers on a break. Evenings bring couples after dinner near Patpong, hotel guests, and the Lumphini Park crowd. Soi Convent and Soi Pat Pong 2 are a short walk if you want food after. Everything we do runs inside Thailand's medical cannabis framework, so the team can walk you through how access works the moment you arrive.
"Silom shows up in more moods than any other part of Bangkok."
We carry cannabis flower from growers we know personally, plus FDA-approved CBD and THC edibles and drinks, health supplements, branded apparel, and accessories. Cannabis flower is a controlled herb under Thai Ministry of Public Health rules, so flower needs a medical cannabis prescription. If it's on our shelves, we'd choose it ourselves.
No upsell, no pressure. If a smaller pack is the right call for you, that's what we'll suggest. Our job is to guide you through the process, not to sell to you.
Free wifi, power outlets, room to slow down. Ask questions and sit down for an in-branch consultation before anything else. Adults 20 and older only, photo ID or passport required.

No. Cannabis is a controlled herb under Thai law, so every purchase is in person at one of our five branches across Bangkok and Koh Samui. Public consumption is also prohibited.
Yes. In Thailand, cannabis flower is for medical use, and every purchase needs a medical cannabis prescription (form ภ.ท.33, also written PT 33). A licensed practitioner issues it after an in-branch consultation and assessment. Siam Green is a licensed dispensary rather than a clinic that employs its own practitioners, so we guide you through the steps and check your photo ID or passport. Visitors should note that foreign prescriptions are not valid in Thailand, and importing or exporting cannabis is prohibited.
Yes. Every branch has staff fluent in English, and most are comfortable across Thai, English, and at least one other language.
Open 11:00 to 03:00 daily. Right on Silom Road, five minutes from Sala Daeng BTS. Bring a photo ID or passport, and our team will walk you through the medical cannabis process when you arrive.
