The closest Siam Green cannabis dispensary to Asok BTS is Siam Green Nana, about three minutes on foot west along Sukhumvit. Our Phrom Phong shop is one BTS stop east. Both open daily 11am to 3am.
Asok is where the BTS Sukhumvit Line and MRT Blue Line meet, with Terminal 21 right on top of the station. From here, Nana is a short walk west and Phrom Phong is one BTS stop east. Cannabis in Thailand is a controlled herb for medical use, so every visit starts with a quick in-branch consultation before you buy.

The Asok intersection is one of Bangkok's busiest transit nodes. BTS Asok and MRT Sukhumvit interchange here, Terminal 21 mall sits directly above the station, and Sukhumvit Soi 21 runs north toward the Westin and Sheraton hotel corridor. Most Sukhumvit visitors pass through Asok at least once on any given trip.
From BTS Asok, our Nana branch is quickest on foot. Come down to the south side of Sukhumvit and walk west toward Nana, past Soi 12. The shop is just past Korea Town, between Soi 10 and Soi 12, about three minutes from the station.
Heading the other way, our Phrom Phong branch is one BTS stop east at Phrom Phong station. Take Exit 3 down, turn around at the bottom of the steps, and we are right there. Phrom Phong is the residential pick: quieter blocks, near EmQuartier and Emporium, a slightly slower service rhythm. Nana is the international pick: the Sukhumvit corridor, near the Soi 11 rooftop strip and Nana Plaza, with more visitor traffic.
Both branches carry the same menu of cannabis flower, plus FDA-approved CBD and THC edibles and drinks, health supplements, branded apparel, and accessories, so the choice comes down to your direction of travel. If you are coming along the MRT Blue Line from Silom, Hua Lamphong, or Chinatown, get off at Sukhumvit (Asok): Nana is a short walk from there, and Phrom Phong is one BTS stop east.
If you are an Asok regular and want to make one branch yours, the rule of thumb is simple. Choose Nana for evening trips that pair with Soi 11 or Sukhumvit Plaza, and Phrom Phong for daytime trips around EmQuartier, Emporium, or Benjasiri Park. Both teams know the Asok-side customer well, both run on-site lounges, and both stock the full menu of flower, CBD and THC edibles and drinks, supplements, merch, and accessories.
Here is how a visit works, because the legal side is simple once you know it. Cannabis flower is a controlled herb under Thai Ministry of Public Health rules and is sold for medical use, alongside FDA-approved CBD and THC edibles and drinks, supplements, merch, and accessories. A licensed practitioner sees you in-branch for a short consultation and assessment, then issues the medical-cannabis prescription you need to buy flower, form ภ.ท.33 (PT 33). Bring photo ID or a passport, and note that the door is for ages 20 and over. Public consumption is not allowed. For visitors, a foreign prescription is not valid in Thailand, and carrying cannabis in or out of the country is prohibited, so the assessment always happens here with us.
Walk-ins are welcome at either branch, no appointment needed. From Terminal 21, Nana is about three minutes on foot to the west; for Phrom Phong, take the BTS one stop east.
