CHIANG MAI: The first clinic to offer both traditional and modern cannabis-based treatments for diseases, such as Parkinson's, has opened its doors in this northern province.

Its 125 medical staff, including 39 doctors and four traditional Thai medicine practitioners, were kept busy as 22 people quickly registered as patients.

"At least five groups of illnesses can be cured, or relieved, by marijuana extracts," Public Health Minister Anutin Charnvirakul said yesterday as he presided over the opening of the clinic at Nakornping Hospital in Mae Rim district.

The diseases listed under modern medicine include Parkinson's, epilepsy and multiple sclerosis. Patients with insomnia, migraine, body pains, neurosis-derived tremors and paralysis are advised to seek traditional treatments provided by the clinic.

"This clinic will be one of 37 under the fourth phase of cannabis-based medical service expansion," he said.

Earlier this month, the minister opened the first stand-alone clinic treating patients with marijuana-based medicine in Nonthaburi.

Thailand, which has a tradition of using cannabis to ease pain and fatigue, legalised marijuana for medical use and research in 2017 to promote the use of cannabis-based medications.

The largest producer of medical cannabis in Thailand is the Public Health Ministry's Government Pharmaceutical Organisation. Kasetsart University's director of medical cannabis research, Natakorn Thasnas, said the university will supply 2,200kg of cannabis to the ministry.
