Cannabis in Khao San, Bangkok

Cannabis in Khao San, Bangkok sits in the backpacker quarter, where signs and window displays are aimed at travellers. That makes the area easy to find but easy to misread, because the old open-sale idea of cannabis no longer applies.

Getting there: no BTS or MRT station is near. Use a taxi or Grab, or take a Chao Phraya Express boat to Phra Arthit pier. The nearest MRT, Sam Yot, is about a 20-minute walk.

What changed in 2026: Flower may now go only to patients, and only a licensed clinic, pharmacy, herbal-product shop or traditional healer may hand it over. The patient needs a PT.33 prescription valid for up to 30 days. Selling by app, courier or vending machine is banned. Because we cannot confirm which listed businesses hold a licence, none appears by name.

Before you choose: A tourist-facing sign does not prove a licence. Ask the staff to show the licence and the prescription process before you pay, and walk away if they cannot. Keep your passport with you.
