If you have been reading old travel blogs, you might think Thailand is a place where you can walk into any street shop and buy recreational cannabis over the counter. That was briefly true. It is not true now — but the answer to the most-asked question is still yes, with conditions.
The 60-second answer: Tourists can still legally buy cannabis in Thailand — but only for medical use, only from a licensed outlet, and only after getting a PT 33 prescription from a licensed Thai practitioner. Smoking in public is illegal. Taking cannabis out of the country is smuggling. Get the prescription, follow the rules, and leave every gram in Thailand when you fly home.
What changed in 2025
On 26 June 2025, Thailand recriminalised recreational cannabis and returned it to a medical-only regime. Cannabis flower is now classified as a “controlled herb,” not a narcotic — but that does not make it a free-for-all. The era of unregulated recreational street sales has ended. Today, cannabis is legal in Thailand for medical use only.

Can tourists buy cannabis? Yes — with a prescription
Here is the good news for travellers: you do not have to be a Thai citizen or resident to buy cannabis legally. Tourists can buy it from a licensed outlet — but only with a PT 33 prescription issued by a licensed Thai practitioner.
Getting one is straightforward:
- Book a consultation with a licensed Thai practitioner — either in person or through a legitimate telemedicine service.
- Have a short consult, typically around 15 minutes. The practitioner assesses whether cannabis is appropriate for your condition.
- Receive your PT 33 — a paper prescription form. Your passport is used for identification.
- Buy from a licensed outlet that dispenses against the prescription in person.
A few important limits apply:
- A PT 33 is valid for up to 30 days.
- Tourist prescriptions are commonly capped at around 30 grams per month.
- With a valid prescription, you may carry up to 30 grams.
- The minimum age is 20. Cannabis is not for pregnant or breastfeeding people.
One thing trips up a lot of visitors: a foreign prescription, or a medical-cannabis card from your home country, is not valid in Thailand. It does not matter if you hold a legal medical card back home — you still need a Thai PT 33.

What about CBD?
If all you want is CBD, the rules are much simpler. CBD products with less than 0.2% THC are legal without a prescription and are sold at pharmacies, wellness shops, and some convenience stores. No consultation, no PT 33 — you buy it like any other wellness product.
Where tourists get in trouble
Buying legally is only half the story. Two things catch travellers out, and the penalties are serious. Keep them separate in your mind, because they are two different offences with two different punishments.
1. Smoking in public
Smoking cannabis in public is illegal — even if you hold a valid prescription. Public smoking, or causing a nuisance through the smell, is punishable under the Public Health Act 1992 by a fine of up to 25,000 THB and/or up to 3 months’ imprisonment. Use your prescription cannabis privately and responsibly, not on the beach or in the street.
2. Taking cannabis home
This is the big one. Do not try to take cannabis out of Thailand. Exporting it without a licence is smuggling — punishable by up to 10 years’ imprisonment and/or a fine of four times the value of the goods.
And the risk does not end at the Thai border. Thai-origin cannabis has been intercepted in the UK, Germany and elsewhere in 2026, and the UK’s National Crime Agency has introduced tougher penalties for travellers caught smuggling. Many destination countries also prosecute you on arrival. That gram of “souvenir” flower can turn into a criminal record in two countries.

Legal vs illegal for tourists — at a glance
| Legal for tourists | Illegal for tourists |
|---|---|
| Buying from a licensed outlet with a PT 33 prescription | Buying without a prescription |
| Carrying up to 30 grams with a valid PT 33 | Smoking in public / causing a smell nuisance |

| Getting a PT 33 via an in-person or legitimate telemedicine consult | Using a foreign prescription or home-country medical card |

Note there are no legal online sales of THC cannabis in Thailand. It must be dispensed in person against a PT 33.
The bottom line for travellers
You can still enjoy legal cannabis in Thailand — but as a patient, not as a tourist stopping at a street kiosk. Book a consultation, get your PT 33, buy from a licensed outlet, stay within your roughly 30-gram limit, and never smoke in public. Then, when it is time to fly home, leave every last gram in Thailand. The prescription that makes it legal here means nothing at the airport, and the penalties on both ends are simply not worth the risk.
