Location

Khon Kaen Hospital is located on Sri Chant Road in Khon Kaen city, the capital of Khon Kaen Province and the largest urban center in Thailand’s Isan (northeastern) region. With a population of over 100,000 in the city proper and significantly more in the greater metropolitan area, Khon Kaen serves as the commercial, educational, and transportation hub for the upper Isan region. The city is home to Khon Kaen University, one of Thailand’s top public universities, and is approximately 450 km northeast of Bangkok, connected by frequent domestic flights, trains, and bus services.

Isan’s Medical Cannabis Hub

As the largest hospital in the upper Isan region, Khon Kaen Hospital’s cannabis clinic serves patients from Khon Kaen Province and neighboring provinces including Udon Thani, Maha Sarakham, and Kalasin. The clinic provides an important medical cannabis access point for this populous region of Thailand.

PT 33 Prescription Required

Buying flower here requires a PT 33 prescription. That has been the rule since 26 June 2025, when cannabis flower was reclassified as a controlled herb for medical use only. Prescriptions come from DTAM-certified doctors, Thai traditional medicine practitioners and a few other licensed professions, and each one covers at most 30 days’ supply. CBD products under 0.2% THC are the exception and need no prescription. For clinics in and around Khon Kaen, see our clinic directory and the PT 33 guide.
