No, recreational weed is not legally permitted in Thailand. Cannabis may be supplied for medical purposes when a patient has a valid prescription issued by an authorised Thai medical professional. These restrictions apply to both Thai residents and foreign tourists.
Thailand removed cannabis from its narcotics list in 2022, leading many people to believe that recreational marijuana had been fully legalised. However, the government tightened the rules on June 26, 2025. Cannabis flower is now treated as a controlled herb, and ordinary recreational sales are prohibited.
Is Recreational Cannabis Legal?
Recreational cannabis is not legally available for unrestricted purchase or use. A person cannot simply enter a dispensary, select cannabis flower and buy it for enjoyment without medical approval.
A licensed seller may provide cannabis flower only for a genuine medical purpose supported by a prescription. Shops that continue selling cannabis freely to walk-in customers may be operating outside the present rules, even when they appear to be established dispensaries.
The change did not place the entire cannabis plant back on Thailand’s narcotics list. Instead, cannabis flower was classified as a controlled herb and made subject to strict medical, licensing and sales requirements.
How Can Someone Obtain Medical Cannabis?
A patient must first be examined by an authorised practitioner. Depending on the circumstances, the prescription may be issued by a qualified medical doctor, dentist, pharmacist, Thai traditional medicine practitioner, applied Thai traditional medicine practitioner, Chinese medicine practitioner or recognised folk healer.
The official prescription form is known as PT 33. It records the patient’s name, nationality, passport or identification number, diagnosis, dosage and prescribed quantity.
A prescription may cover no more than 30 days of treatment. The seller must retain the prescription for inspection for one year. Cannabis cannot legally be supplied merely because a customer claims to have pain, insomnia or another condition without receiving the required medical assessment.
Can Tourists Buy Weed in Thailand?
Tourists are subject to the same medical-use requirement. A foreign visitor must obtain a prescription issued in Thailand by an authorised practitioner before buying, possessing, using or transporting cannabis flower.
A passport may be used for identification, but a passport alone does not give a tourist permission to purchase cannabis. A foreign medical-marijuana card or prescription may not automatically be accepted as legal authority in Thailand.
Thailand’s official tourism guidance warns visitors not to assume that products openly displayed in shops are lawful. A shop may be violating the rules by selling cannabis without prescriptions.
Where Can Cannabis Be Sold?
Cannabis flower can be supplied only through properly licensed businesses operating within the medical framework.
Online cannabis sales and sales through vending machines are prohibited. Advertising cannabis is also forbidden. Businesses cannot sell cannabis flower in certain locations, including temples, dormitories, public parks, zoos and amusement parks.
Dispensaries are increasingly being inspected for compliance. Thai authorities reported inspecting more than 1,200 cannabis establishments during a recent enforcement period, with some inspections resulting in arrests, licence suspensions and seizures.
Is Smoking Weed in Public Legal?
No. Smoking cannabis in public places is illegal, particularly when the smoke or smell creates a public nuisance.
Restricted places can include streets, parks, shopping centres, schools, hotels, restaurants, beaches and other areas accessible to the public. A person causing a cannabis-related public nuisance may face imprisonment of up to three months, a fine of up to 25,000 baht, or both.
A private hotel room is not automatically a lawful smoking location. Hotels, landlords and property owners may prohibit smoking or cannabis use. Smoke entering corridors, neighbouring rooms or public areas can also result in complaints and enforcement action.
Are Cannabis Edibles and Oils Legal?
The legal position depends on the product’s ingredients, THC level, approval and purpose.
Cannabis extracts containing more than 0.2% THC by dry weight generally remain Category 5 narcotics. Certain properly approved CBD or low-THC products containing no more than 0.2% THC may be lawful when they comply with Thai food, medicine or herbal-product regulations.
Consumers should not assume that homemade edibles, cannabis oils, vape cartridges or products sold without proper labels are legal. Cannabis vaping creates another legal risk because electronic cigarettes and vaping devices are restricted in Thailand.
Can People Grow Cannabis at Home?
Cultivation is regulated and should not be treated as an unrestricted personal right. Registration, licensing and medical-production standards may apply depending on who is growing cannabis and what will be done with the plants.
Commercial cultivation, processing, research, sale and export of cannabis flower require official permission. Tourists should not grow cannabis during their stay or assume that the rules allowing certain Thai growers to register apply automatically to foreign visitors.
Can Cannabis Be Taken Through an Airport?
Cannabis should never be taken into or out of Thailand without specific government authorisation. A prescription allowing medical use inside Thailand does not automatically authorise international transportation.
Thai Customs increased enforcement against illegal cannabis exports in June 2026. Authorities now impose a fine calculated at 30,000 baht for every kilogram seized, require forfeiture of the cannabis and may refer unpaid or serious cases for criminal investigation.
Cannabis should also not be carried onto an international connecting flight, posted overseas or packed inside checked luggage.
Can You Drive After Using Cannabis?
Driving while impaired by cannabis is illegal. This applies to cars, motorcycles and other vehicles.
Having a valid medical prescription does not allow someone to drive while intoxicated. Police may rely on driving behaviour, physical symptoms, statements and medical testing when investigating possible impairment.
The Current Legal Position
Recreational weed is not legal in Thailand. Cannabis flower is available only for approved medical use through an authorised practitioner and a prescription covering no more than 30 days.
Tourists should not buy cannabis from ordinary walk-in sellers, smoke in public, carry it across Thailand’s border or rely on information written before the June 2025 rule change. Cannabis remains visible in many tourist areas, but its availability does not mean unrestricted purchase or recreational use is lawful.
