Cannabis has been part of Bangkok’s history for thousands of years, transitioning from ancient medicine and spiritual rituals to a thriving medical cannabis industry today. Here’s what you need to know:
- Historical Roots: Introduced around 2000 BCE from India, cannabis was used in Thai medicine for pain relief, muscle relaxation, and easing childbirth.
- Prohibition Era: Banned in 1934 and later classified as a Category 5 drug in 1979, cannabis use was heavily restricted for decades.
- Legalization: Thailand became the first Asian nation to legalize medical cannabis in 2018 and fully decriminalized it in 2022.
- Current Industry: By 2025, Bangkok has over 11,200 licensed dispensaries, offering medical treatments, wellness tourism experiences, and cannabis-infused therapies.
Today, Bangkok is a leader in Asia’s cannabis market, balancing strict regulations with growing demand for medical and wellness applications. However, challenges like public health concerns and policy shifts remain key issues for the industry’s future.
Early History of Cannabis in Bangkok
Trade Routes from India
Cannabis made its way to Southeast Asia around 2000 BCE, traveling along ancient trade routes from India [1][3]. The shared term ganja in both Thai and Indian languages highlights this historical connection [1][3]. These early trade exchanges laid the groundwork for cannabis's role in Thai medicinal practices.
Medical Uses in Thai History
Thai healers used cannabis extensively for its therapeutic benefits. It was employed to ease pain, reduce inflammation, calm digestive issues, and alleviate headaches [1]. Muay Thai fighters, laborers, and women during childbirth also relied on its muscle-relaxing and pain-relieving properties [3].
Role in Thai Society
Cannabis grew beyond its medicinal uses during the Ayutthaya Kingdom, becoming a cultural symbol tied to nature and harmony [1]. It played various roles in Thai society, including:
- Spiritual practices: Used in Buddhist rituals and ceremonies.
- Traditional medicine: A key component in healing practices.
- Everyday applications: Utilized in fiber production and cooking.
Ancient Thai texts highlight cannabis's presence in both ceremonial and medicinal contexts, showing its deep-rooted significance in early Bangkok culture [1].
From Ban to Legal Status
Cannabis Ban Period
In the early 20th century, Western drug policies influenced Thailand to outlaw cannabis. The Cannabis Act B.E. 2477 (1934) prohibited its cultivation, possession, and distribution, setting the stage for decades of strict enforcement [4].
The 1979 Narcotics Act escalated these restrictions by classifying cannabis as a Category 5 drug. This came with harsh penalties, disrupting traditional medicinal practices and cultural norms [4][1].
During the Vietnam War and into the late 1980s, Bangkok became notorious for its illegal cannabis trade. The infamous "Thai Stick" gained global attention, with smuggling routes stretching from Australia to South Africa. At the time, the U.S. Drug Enforcement Administration labeled Thailand as Southeast Asia's leading cannabis producer [4].
After decades of prohibition, things began to shift in 2018.
Steps to Legalization
Thailand took a groundbreaking step in 2018, becoming the first Asian country to legalize medical cannabis [2]. Here are some key milestones:
| Year | Event | Impact |
|---|---|---|
| 2018 | Medical cannabis legalized | Thailand leads Asia in allowing medical use [2] |
| 2022 (June 9) | THC limit set | Cannabis extracts with less than 0.2% THC legalized [2] |
| 2022 (June) | Full decriminalization | Permitted growing, trading, and medical use of cannabis [5] |
This shift from prohibition to regulated use has positioned Bangkok as a leader in Asia's cannabis market. Following legalization, the industry grew quickly. By 2022, Thailand's cannabis market was valued at 28 billion baht (around $800 million), with projections estimating growth to 336 billion baht (roughly $9.6 billion) by 2030 [6].
"Thailand will promote cannabis policies for medical purposes. There has never once been a moment that we would think about advocating people to use cannabis in terms of recreation – or use it in a way that it could irritate others", said former health minister Anutin Charnvirakul [5].
The shift has been transformative. Nearly 8,000 dispensaries have opened nationwide, and over 1 million households have registered to grow cannabis [8]. However, there are signs of a policy adjustment. The government is now working to limit recreational use while continuing to support medical applications [7]. Health Minister Cholnan Srikaew emphasized this cautious approach, stating, "without the law to regulate cannabis it will be misused" [7].

Cannabis in Bangkok Today
Bangkok has transformed its ancient medicinal use of cannabis into a thriving modern industry.
Health Tourism Growth
Bangkok's legal cannabis framework sets it apart from nearby countries, drawing wellness tourists from around the globe [9]. Luxury venues have embraced cannabis as part of their wellness offerings. For example, the Mandarin Oriental, Bangkok collaborates with Sawasdee Clinic to provide cannabis leaf oil massages [9]. Similarly, Anantara Spas offer therapies aimed at improving sleep, reducing stress, and promoting relaxation.
"For anyone with insomnia and sleep disorders, I highly recommend trying cannabis" [9].
These wellness offerings have not only attracted visitors but also contributed to the rapid growth of Bangkok's cannabis economy.
New Business Landscape
Tourism has sparked a boom in the cannabis industry. Currently valued at $1.2 billion, Bangkok's cannabis market is expected to triple within the next five years [12].
Entrepreneurs like Boss Asakon Singsikornkun and Jamiez Rayzoowaht Spaunpullsate are capitalizing on this growth. They are working on a multi-level cannabis complex in Chinatown, which will include educational spaces, massage services, and the Rema Wellness premium medical spa [12].
Local dispensaries, such as House of Pot in Silom, have also gained a reputation for offering personalized consultations and combining cannabis with holistic health practices.
Wellness Applications
Riding the wave of tourism and business expansion, wellness centers in Bangkok are blending traditional Thai medicine with cannabis-based treatments [11]. These centers address a range of issues, including stress, anxiety, chronic pain, sleep problems, and appetite stimulation.
The Service 1921 Restaurant at Anantara Chiang Mai Resort has taken it a step further by incorporating cannabis into Thai cuisine, offering a unique culinary experience [9].
"There are people now flying from Malaysia and Singapore specifically to use, to buy, and to have this cannabis experience. And I can tell you CBD massage really, really works, which is why it's become a big thing in the sports industry in America." – Kris Thirakaosal, Managing Director of the Golden Triangle Group (GTG) [9]
While the industry faces challenges like shifting regulations and competition [10], clear policies will be essential for sustaining its growth.
Rules and Guidelines
Current Laws
Thailand's cannabis laws have undergone changes since decriminalization, with Bangkok navigating a careful balance between traditional practices and modern medical use. As of February 2025, cannabis remains legal but under strict regulations. These rules aim to blend Thailand's cultural heritage with advancements in healthcare.
Here are some of the key regulations:
- Public smoking or vaping can lead to fines of up to ฿25,000 ($714) under the Public Health Act [2].
- Possession is capped at 30 grams of cannabis or 30 milliliters of extracts [2].
- Sales are prohibited for individuals under 20, as well as pregnant or breastfeeding individuals [2].
- Recreational use could result in proposed fines of up to ฿60,000 ($1,700) [7].
"Drugs are a problem that destroys the future of the nation." - Srettha Thavisin, Former PM [6]
The Health Ministry has labeled cannabis a "controlled herb", which means cultivation and sales require proper licensing. Online sales are banned, and all transactions must happen in physical stores [6]. These regulations also define the framework for medical cannabis use, ensuring that treatments are handled responsibly.
Qualifying Health Conditions
Bangkok's medical cannabis program operates through licensed healthcare providers and approved clinics. The FDA has authorized all Public Health Ministry hospitals to prescribe cannabis treatments for specific conditions [2].
Cannabis prescriptions are commonly used for:
- Chronic pain relief
- Sleep issues
- Anxiety and stress management
- Appetite stimulation
- Certain neurological disorders
To access medical cannabis, patients must consult licensed physicians who review their conditions and provide the necessary documentation. This process requires proper medical records and compliance with Thai healthcare standards. Licensed dispensaries are the primary source for regulated cannabis products, ensuring safe and controlled access.
Licensed Dispensaries
Bangkok is home to many authorized dispensaries, forming part of Thailand's network of over 11,200 approved locations [2]. Some notable dispensaries include:
| Dispensary | Location | Features |
|---|---|---|
| House of Pot | Silom | Licensed medical consultations |
| Siam Green Cannabis Co. | Phrom Phong, Nana, Chinatown | Licensed dispensary services |
| MedMen Bangkok | Sukhumvit Soi 11, Watthana | Licensed medical guidance |
Product prices generally range from ฿450 to ฿900 ($13–26), and sellers are required to verify customer eligibility before completing a sale [13]. For those interested in cultivation, individuals must register with Thailand's Food and Drug Administration [2]. The government has also encouraged home growing, previously announcing plans to distribute one million cannabis plants to households [2].
Looking Ahead
Business Growth
Thailand's legal cannabis market is set for impressive growth. Forecasts suggest the market could expand from $1.31 billion in 2024 to $1.70 billion by 2025, with an annual growth rate of 33.0% projected through 2030 [14]. Several factors are fueling this surge:
| Factor | Impact |
|---|---|
| Medical Tourism | Growing interest from international patients exploring alternative treatments |
| CBD Products | Rising demand for wellness products like oils and tinctures |
| Export Potential | Positioned to serve the Asia-Pacific region |
| Research Development | Increased funding for medical cannabis studies |
Local businesses are stepping up to seize these opportunities. Companies such as Medicana Lab Co. and House of Pot are investing heavily in CBD production and aiming to expand into international markets [14].
"This is the most fair and open cannabis market there is in the world right now by far."
– Tai Taveepanichpan, owner of Four Twenty [15]
However, with rapid growth come significant challenges.
Current Issues
Despite the optimistic outlook, the industry faces notable hurdles. According to the Health Ministry, cases of cannabis-related psychological issues rose from 37,000 in 2022 to over 63,000 in 2023 [6].
Some of the key challenges include:
- Regulatory Uncertainty: The Thai government plans to ban recreational cannabis use by the end of 2024 [14].
- Quality Control Problems: A lack of a centralized tracking system makes it difficult to recall contaminated products [15].
- Public Health Risks: Cannabis-related psychosis cases nearly doubled, increasing from 10,619 to 20,804 in the year following decriminalization [15].
These issues must be addressed for Thailand to maintain its competitive edge in the cannabis market.
"Everyone agrees that it needs to be controlled. But government agencies lack the data to make informed decisions regarding cannabis regulation."
– Prasitchai Nunual, Writing Thailand's Cannabis Future [15]
Industry leaders are already taking steps to tackle these problems. Some dispensary owners have shown a willingness to pay higher taxes if the funds are directed toward public health programs [15]. However, frequent policy changes could discourage foreign investors and threaten the survival of legitimate cannabis businesses [8].
The industry's future hinges on clear regulations and effective oversight. With the right approach, Thailand could cement its place as a key player in the medical cannabis sector across Southeast Asia.
Summary
Bangkok’s relationship with cannabis stretches back thousands of years, beginning around 2000 BCE when it was introduced from India. Over time, its role shifted from traditional medicine and spiritual practices to prohibition, and now, to its modern use in medical treatments.
Here’s a snapshot of key milestones:
| Period | Development | Impact |

| 1934–2018 | Prohibition | Completely banned under the Marijuana Act |
| 2018 | Medical Legalization | Became the first Southeast Asian nation to allow medical use |
| 2022 | Decriminalization | Launched a regulated cannabis industry |
| 2025 | Market Growth | Over 11,200 licensed dispensaries in operation |
As the industry grows, public health concerns have surfaced, leading to tighter oversight and regulation.
"Thailand will promote cannabis policies for medical purposes. There has never once been a moment that we would think about advocating people to use cannabis in terms of recreation – or use it in a way that it could irritate others" [5]
Bangkok’s approach focuses on maintaining strict regulations to support its medical cannabis market while curbing recreational use. This balance is evident in the licensing system and the expanding cannabis industry across the city [2].
