History of Cannabis Laws in Thailand 

Thailand has a long-standing relationship with cannabis, as it has been used for traditional medicinal and cultural purposes for centuries.

This classification resulted in severe penalties for cannabis-related offenses.

Legalization of Cannabis for Medical Use

In 2018, Thailand took a significant step forward by becoming the first Southeast Asian country to legalize cannabis for medical purposes. The amendment to the Narcotics Act permits the cultivation, production, import, export, possession, and use of cannabis for medical research, treatment, and traditional medicine. 

This change in Cannabis laws in Thailand allowed patients, medical professionals, and businesses to explore the potential benefits of cannabis. While under cannabis laws in Thailand, in June 2022, Thailand’s Food and Drug Administration removed marijuana and hemp from the Category 5 narcotics list. 

Conditions for Medical Use

Under the current regulations, individuals seeking to use cannabis for medical purposes must obtain a medical cannabis prescription from a licensed physician. These prescriptions are only available for specific conditions, including Chronic pain, Epilepsy, Multiple Sclerosis, Nausea caused by chemotherapy, and palliative care. The Ministry of Public Health oversees the issuance of licenses for medical practitioners and facilities involved in medical cannabis.

Cannabis Research and Development

The Thai government has actively encouraged research and development in the cannabis industry. Licensed entities, including universities, research institutions, and private companies, are authorized to conduct scientific research, develop cannabis-based medications, and cultivate cannabis plants for medical purposes. The Office of the Narcotics Control Board (ONCB) regulates and monitors these activities.

Recreational Use and Possession

While cannabis remains illegal for recreational use and possession in Thailand, the government has shown a willingness to explore the potential benefits of cannabis in the future. Several advocacy groups and lawmakers have called for decriminalizing or legalizing cannabis for recreational purposes, but no significant changes have been implemented.

Penalties and Enforcement

Although medical use is legal, strict penalties exist for the unauthorized use, possession, production, or distribution of cannabis. Violators can face imprisonment, fines, or both, depending on the severity of the offense. The severity of the penalty depends on various factors, including the amount of cannabis involved and the intent of the individual.

Import and Export Regulations

Cannabis and cannabis-derived products can be imported and exported under specific conditions for medical and research purposes. The Thai Food and Drug Administration (FDA) and the ONCB regulate and oversee these activities. Strict controls are in place to prevent illegal trafficking and ensure compliance with international drug control treaties.
