Cannabis Product Forms and Thai Rules

Last updated October 2026.

Cannabis is sold in more forms than most people expect. This guide explains what each one is, in plain terms, along with the Thai legal points that apply. It is an overview of products, not a recommendation to use any of them, and it does not give dosing advice.

At a glance

Flower and pre-rolls need a prescription from a Thai-licensed practitioner, and each batch should have a CoA.
Hash is a concentrate, typically much stronger than flower.
Edibles can take up to two hours to begin to take effect, and effects can last up to 12 hours.
Extracts over 0.2% THC by weight need a licence, and cannabis cosmetics need a Thai FDA licence.
Vapes and e-cigarettes have been banned in Thailand since 2014, for tourists as well as residents.

First, the legal basics

Since June 2025, cannabis flower in Thailand has been a controlled herb. Licensed shops may only supply it to adults aged 20 or over with a prescription or medical certificate from a Thai-licensed practitioner, covering no more than 30 days. It may not be supplied to pregnant or breastfeeding women. Selling cannabis online or through other electronic channels is prohibited, as is advertising.

The rules are still moving: in September 2026 the cabinet approved a draft cannabis control bill limiting cannabis to medical use, which now goes to parliament. Our guide to cannabis rules in Thailand for visitors is kept up to date.

Flower, pre-rolls and hash

Flower

Flower is the dried and cured bud of the female cannabis plant, and it is the form most people picture. In Thailand, flower sold by licensed shops must come from a GACP-certified site, such as a GACP-certified Thai farm, and each batch should have a certificate of analysis (CoA) showing its THC and CBD content. A CoA is a laboratory report for a specific batch: the batch number on the label should match the one on the report, and you can ask which laboratory carried out the tests.

Pre-rolls

A pre-roll is ground flower already rolled in paper. Because pre-rolls are made from flower, the same rules apply: a prescription is needed, and they may not be smoked in public places or on shop premises.

Hash

Hash is a concentrate made by collecting the sticky, resin-filled trichomes from the cannabis plant and pressing them into a solid or semi-solid form. Traditional methods use hand-rubbing or sieving; modern ones often use ice water. Because it is concentrated, hash is typically much stronger than flower. Our article on hash quality and adulteration goes into more detail.

Edibles, tinctures and topicals

Edibles

Edibles are foods or drinks containing cannabis. In Thailand, producing food is regulated by the Thai FDA under the Food Act, and only certain plant parts and extracts are permitted as food ingredients. Cannabis extracts containing more than 0.2% THC by weight remain controlled and need a licence, and cannabis may not be added to infant food, young children’s food or energy drinks.

The main thing to understand about edibles is timing. Health Canada notes that it can take up to two hours to begin to feel the effects of cannabis that is eaten or drunk, and up to four hours to feel the full effects. Effects can last up to 12 hours, and some residual effects up to 24 hours. That delay is why people sometimes take more than they meant to, thinking the first portion has not worked.

Edibles can also be mistaken for ordinary snacks. Store them safely, out of the reach of children and pets.

Tinctures and oils

Tinctures and oils are liquid extracts of cannabis compounds in a carrier such as oil or alcohol. In Thailand, how they are regulated depends on their THC content and how they are sold. Extracts above the 0.2% THC threshold need a licence, and products sold as medicines need Thai FDA review and registration under the Drug Act.

If you are considering a cannabis oil for a health reason, that conversation belongs with a Thai-licensed medical practitioner.

Topicals

Topicals are creams, balms and lotions made with cannabis ingredients and applied to the skin. In Thailand, cosmetic products containing cannabis or hemp ingredients need a Thai FDA licence under the Cosmetics Act. As with any cosmetic, read the ingredient list on the label, and ask the seller how the product is licensed. We do not make claims about what topical products do.

Vapes, smoking and borders: what is not allowed

Vapes are the product most likely to catch visitors out. E-cigarettes and vapes have been banned in Thailand since 2014, and the ban covers tourists as well as residents. In April 2026, Fox News reported the case of two tourists who were fined 40,000 baht after being caught vaping on a beach, and warned they could face up to five years in prison if caught again.

The ban applies to the device, whatever is in it. Do not bring vapes, cartridges or e-liquids into Thailand, and do not buy them here. The other places where cannabis may not be smoked or taken are:

Public places: smoking cannabis in public places is not permitted. Police can use public nuisance law, with penalties of up to 25,000 baht and/or three months in prison.
Dispensary premises: licensed shops may not sell flower for smoking on their premises.
Across borders: cannabis may not be taken out of Thailand. Since June 2026, smuggling penalties include up to 10 years in prison, with Customs fines calculated at 30,000 baht per kilogram.
