Visiting Chiang Mai and wondering how legal medical access works for foreigners? This guide explains the regulated route — why a Thai consultation and prescription are required, what documents you need, and why a prescription from home is not valid here.
Book a Consultation Talk to usForeign visitors and residents can access medical cannabis legally in Thailand through the same regulated route as Thai nationals. There is no separate or informal channel for tourists — access runs through a licensed clinic and a licensed practitioner, which is exactly how the system is designed to work.
