2020 Global Cannabis Guide Chapters - Thailand

World Law Group

World Law Group

[author: Jessada Sawatdipong]*

World Law Group member firms recently collaborated on a Global Cannabis Guide that provides a brief overview of laws and policies regarding the use of cannabis in various jurisdictions. It briefly outlines information on the most important legal issues, from relevant legislation and general information to special requirements and risks.

The guide does not claim to be comprehensive, and laws in this area are quickly evolving. In particular, it does not replace professional and detailed legal advice, as facts and circumstances vary on a case-by-case basis and country-specific regulations may change.

This chapter covers Thailand. View the full guide.


I. Introduction

1. Identify the geographic scope and limits of your answers to the questions below.


History [ref. 3 Wikipedia]

The marijuana/cannabis market in Thailand has a long history. Cannabis had been part of Thai culture (as a traditional medicine) until it was banned in 1930’s. Thailand was once the land of the world’s most powerful “ganja”. It appears to have been introduced to Thailand from India. Cannabis has historically been used in Southeast Asia as an ingredient, a kitchen condiment, a medicine and a source of fiber. Laborers were known to use it as a muscle relaxer.

Cannabis can be found sold in bars and restaurants in certain parts of Thailand. Cannabis dealers sometimes work with police who shakedown customers and demand a bribe.

Criminalization [ref. 3 Wikipedia]

The possession, sale and use of marijuana/cannabis in Thailand was criminalized by the Cannabis Act BE 2477 (1935), the Narcotics Act BE 2522 (1979) and the Psychotropic Substances Act BE 2518 (1975).

The weed industry resulted in draconian drug laws applicable to both users and dealers.

Thailand reportedly has the largest prison population in Southeast Asia. Inmates convicted of drug offenses make up the largest percentage of the population.

Given the fact that the new Thai government appears supportive of developing the cannabis industry, it is likely that foreign investors will be encouraged by liberal policies, and need to establish medical grade cannabis facilities, and in due course recreational cannabis.

Cannabis Industry Overview

Investors should spend some time understanding how the cannabis industry is growing in recent years in states in the USA, Canada, etc. which have legislation and safeguards in place. On the one hand, Thailand has a grass-roots culture hundreds of years old. However, recent advances in regulation in a number of jurisdictions provide a number of guidelines which are relevant to growing the industry in Thailand. Each of the following subjects is very relevant:

1. Cultivation. Problems of over-production and low crop prices.

2. Extraction. Capital intensive, with many brands, concentrates and vape pens. Testing labs and ancillary firms.

3. Retail. Medical marijuana dispensaries and retail stores.

4. Export. Challenges of foreign market entry.

5. Import. Need for high standards for imports into Thai market.

The vertically-integrated cannabis companies provide helpful guidance.

II. Legislation

2. Please provide links to applicable statutes and regulations.

A. Is there any pending legislation that could materially alter applicable statutes or regulations?

B. Is there any proposed legislation that could materially alter applicable statutes or regulations?

See attachment, “Narcotics Act B.E. 2522 (1979) as amended up to Narcotics Act (No. 7) B.E. 2562 (2019).”

3. Are cannabis laws in your jurisdiction pretty well settled or are they constantly changing in material ways?

No. The legalization of medical cannabis was enacted only in February 2019. There are a number of draft notifications and ministerial regulations under review. The amendment to the Narcotics Act allow cannabis to be used only for medical, science and research and development.

Recent Thai Legislation

Hemp has been approved for use in industry since 2018. Under a regulation, which came into effect on January 5, 2018, licenses for growing of hemp for industrial and medical purposes could be obtained. It did not address marijuana or any other forms of cannabis.

Thailand made history in December 2018 by becoming the first country in Southeast Asia to legalize medical marijuana. The Narcotics Act BE 2522 (1979) as amended up to Narcotics Act (No. 7) BE2562 (2019) (“NA”) came into effect on 19 February 2019. This followed years of efforts to legalize medical marijuana, based on evidence that the plant can be used to treat diseases, etc. See summary of the NA which focuses on cannabis after paragraph 9 below.

III. General information (e.g., governing bodies, licenses, import/export)

4. What governing body regulates/licenses or enforces activities that are allowed in your jurisdiction?

Under the Narcotics Act, the Ministry of Public Health.

5. What cannabis functions are allowed in your jurisdiction? E.g., growing, processing, retailing.

See “Cannabis Industry Overview” above, and question 6 below.

6. What sales or use is allowed in your jurisdiction? E.g., edibles, vaping, tinctures, food additives, etc.

A. Are the rules different for medical vs. adult recreational use?

B. Are retail sales of any cannabis products restricted to specific retail channels? E.g., medical dispensaries, government-owned stores, etc.

B. Please describe restrictions on the import of cannabis seeds.


8. Does your region distinguish between different types of cannabis products? (E.g., high or low concentrations of


A. If so, what distinctions exist?

B. If so, briefly describe the differences.

C. Identify any related laws that should be considered when answering this question.

This summary of the NA focuses on cannabis, not the many other narcotics governed by the NA.

  • The NA includes 106 Sections.

  • The NA repealed 7 laws (Narcotics Act, no. 2, no. 3, no. 4, no. 5, Marijuana Act and Kratom Plant Act).
  • Narcotics are classified into 5 categories. Category V consists of narcotics which are not included in categories I to IV, such as marijuana, kratom plant, (including cannabis).Section 26/5 provides that the licensing authority may issue a license to produce, import, export, distribute or possess narcotics of category 5 only when the applicant is:

  • Rules governing advertising are prescribed in Chapter 7.

There has been further clarification by Ministry of Public Health (MoPH) notifications that identify forms of medical cannabis allowed for approved use. These include (1) registered drugs per the Drug Act; (2) Thai traditional medicines having approved compositions (now 16 formulas); and (3) drugs approved for the Special Access Scheme. There have been clarifications of specific qualifications of Thai traditional practitioners having authority to prescribe traditional cannabis medicines. There is a complex network of who can be licensed for what purposes under draft implementing regulations.

The pathway for FDA medical cannabis licensing will be set out in implementing regulations, which have been circulated for comment. There is a complex network of who can apply for licenses, which seeks to ensure control over the process. Participation by foreigners is strictly restricted for the first 5 years, starting February 19, 2019. During this period, state agencies may obtain licenses to produce, import or export cannabis; and a private entity may act only jointly with a state agency to acquire a license.

On August 31, 2019, a new notification of Ministry of Public Health came into effect, providing new exceptions for the following:

For marijuana and hemp:

  • Marijuana or hemp stalks, stem cores and fibers, if dried, and products made of such dry parts;
  • CBD extracted from marijuana or hemp, if having at least 99% purity and no more than 0.01 percent by weight of THC;
