⚠ Critical Update — Cannabis is Effectively Illegal Again in Thailand
Following the 2024 Narcotics Act amendment, cannabis containing more than 0.2% THC is classified as a Category 5 narcotic in Thailand. Recreational use by foreigners or Thais is illegal. This page reflects the legal situation as of March 2026. Seek legal advice for your specific situation.
In 2022, Thailand made headlines worldwide when it removed cannabis from the list of Category 5 narcotics — the first Asian country to do so. Dispensaries opened on every Phuket street corner. Tourists wandered in openly. It felt like a fundamental shift.
It wasn't. By 2024, after two years of political pressure and a change in government, the Narcotics Act was amended and cannabis containing more than 0.2% THC was re-criminalised for recreational purposes. The dispensaries have mostly closed. The legal situation is murky, the enforcement is inconsistent — and for expats, the risk is significant.
Here's a clear, honest rundown of where things stand in Phuket in 2026.
Legal Status Summary — March 2026
| Activity | Legal Status | Risk Level | Notes |

| Possession for recreational use | Illegal | High | Up to ฿300,000 fine and/or imprisonment |
| Medical cannabis (with prescription) | Legal | Low (with docs) | Requires Thai doctor's prescription; obtain from licensed pharmacy only |
| Hemp-derived CBD (<0.2% THC) | Grey Zone | Medium | Not explicitly illegal but regulatory status unclear; FDA approval needed |
| Cannabis cultivation (home) | Illegal | Very High | No longer permitted since 2024 re-criminalisation |
| Sale/distribution of cannabis | Illegal | Very High | Commercial operation requires full medical licensing |
| Importing cannabis/CBD products | Illegal | Very High | Airport risk — no foreign prescriptions accepted |
| Consuming in public spaces | Illegal | High | Even medical patients cannot use in public |
What Changed — The Timeline
June 2022 — Delisting & the Gold Rush
Under then-Prime Minister Prayuth Chan-o-cha's government, cannabis was removed from the Schedule 5 narcotics list. The stated intention was medical and agricultural use, but the absence of clear recreational regulations created a legal grey zone. Dispensaries opened across Phuket, particularly in Patong, Kata, Phuket Town and Rawai. By early 2023 there were over 200 cannabis shops on the island.
2023–2024 — Political Pressure & the Reversal
Public health advocates, conservative politicians and the military raised concerns about recreational use, particularly by younger Thais. The Pheu Thai government that came to power in 2023 had cannabis re-criminalisation in its policy platform. After months of delays, the Narcotics Code Amendment Act passed in late 2024, reclassifying cannabis containing more than 0.2% THC as a Category 5 narcotic.
2025–2026 — Inconsistent Enforcement
The transition has been messy. Licensed medical dispensaries continue operating under the Public Health Ministry framework. Unlicensed dispensaries that pivoted to "wellness" and CBD products continue to operate in legal ambiguity. Police enforcement has been inconsistent — some shops operate openly with apparent tolerance; others have been raided. For expats, this inconsistency does not reduce your legal risk.
The Expat Risk Picture
Thai courts have historically treated foreigners found in possession of narcotics harshly. A conviction can result in immediate deportation and visa blacklisting in addition to criminal penalties. The "everyone's doing it" environment of 2022–2024 no longer exists. Treat cannabis the same way you'd treat heroin — as something that could end your Phuket life overnight.
Medical Cannabis — What Is Legal
Medical cannabis use is legal in Thailand under the following conditions:
- You have a prescription from a Thai-registered physician
- You obtain the medication from a licensed medical cannabis pharmacy or hospital pharmacy
- You are using only the prescribed amount and not distributing to others
- You do not consume in public spaces
Bangkok Hospital Phuket (076-254-425) and Siriroj Hospital (076-361-888) both have doctors trained in medical cannabis prescribing. You will need to demonstrate a qualifying medical condition — the list includes chronic pain, epilepsy, anxiety disorders, Parkinson's, and others. The consultation process is formal and the prescription covers specific products and dosages.
Foreign prescriptions for cannabis, CBD oil or related products have no legal standing in Thailand. If your home doctor prescribes medicinal cannabis, that prescription cannot be used to import, purchase or possess cannabis in Thailand. You need a Thai prescription from a Thai doctor.
CBD Products — The Grey Zone
Hemp-derived CBD products containing less than 0.2% THC are not explicitly illegal under the 2024 amendment. However, the Thai FDA's regulatory framework for these products is still being developed. Products sold in Thai pharmacies and licensed health shops are generally in a safer position. Imported CBD products from other countries remain a risk at border crossings, where customs officers may not distinguish between legal and illegal concentrations.
Our advice: If you use CBD products medicinally, purchase only from licensed Thai pharmacies or medical providers. Do not bring CBD products into Thailand from abroad.
What This Means for Phuket Expats — Practical Guidance
If You Have Never Used Cannabis in Thailand
Nothing changes for you. The legal situation is clearer now than the confusing grey zone of 2022–2024.
If You Used Cannabis During the 2022–2024 Period
Stop. The legal grey zone that existed then no longer exists. Any activity that continues from that period carries criminal risk that did not exist in the same way previously.
If You Have a Medical Need
Consult with Bangkok Hospital Phuket or Siriroj. Their medical cannabis programs are legitimate, properly licensed and the safest route. Do not source medication from unlicensed shops regardless of what they claim about their status.
If You Are Travelling To or Through Thailand
Do not bring any cannabis products across the Thai border. This includes CBD oil, hemp products, and vapes. Even if your product is legal in your home country, Thai customs applies Thai law. Declaration will not protect you from prosecution — it may simply result in more formal processing of a charge.

What Happened to the Dispensaries?
The roughly 200+ cannabis dispensaries that opened in Phuket after 2022 have had varied outcomes:
- Licensed medical dispensaries: Continuing to operate legally under Public Health Ministry licensing. Usually based near hospitals or in medical districts. Phuket Town and Patong areas.
- Pivoted to CBD/wellness: Many shops converted to selling hemp products, CBD oils, and "wellness" products under the 0.2% THC threshold. Legal status of specific products varies.
- Closed: A significant proportion of the recreational dispensaries have closed since 2024, particularly following enforcement actions in tourist areas.
- Underground: Some operations continue illegally. Approaching these carries obvious risk — not just criminal prosecution, but also fraud risk (misrepresented products, police informers).
⚠ Specific Warning About Bangla Road and Patong
In the peak of the dispensary era (2022–2024), Bangla Road in Patong had multiple cannabis shops operating openly. These are now either closed, converted, or operating illegally. Do not assume that because something is openly visible it is legal. Police enforcement in Patong has increased significantly since 2024.
The Broader Drug Safety Picture in Phuket
Thailand takes all drug offences seriously. It is worth understanding the broader context:
- Heroin, cocaine, methamphetamine: Category 1 narcotics — extremely serious charges, mandatory prosecution.
- MDMA / ecstasy: Category 1 narcotic. Extremely common at nightlife venues in Phuket — extremely dangerous legally. Possession can result in years of imprisonment.
- Prescription medications: Some medications legal in your home country (Adderall, Ritalin, certain benzodiazepines) are restricted in Thailand. Bring original packaging and a doctor's letter if you rely on any prescription medication.
- Ketamine: Medical anaesthetic; possession without prescription is illegal.
