ThaiCannaMed: How to Get a PT33 Cannabis Prescription Online in Bangkok

For travelers planning to visit a cannabis dispensary in Bangkok, the question of how to obtain a medical prescription has become more relevant since Thailand tightened its cannabis regulations in 2025. A prescription document known as PT33 is now required to purchase cannabis flower legally, and many dispensaries in the city have introduced a dedicated system to make that step manageable on the same visit.

ThaiCannaMed is the telemedicine service behind that process. From observation at multiple OG Distribution locations in Bangkok, this system has become the standard route for both tourists and residents to obtain a PT33 prescription — without the need to visit a separate medical facility beforehand.

This article covers what ThaiCannaMed is, what PT33 means under Thai law, what the in-store process looks like in practice, and how the medical card and prescription system works across the OG network.

1: What ThaiCannaMed Is and What It Provides

ThaiCannaMed is a Bangkok-based online telemedicine service that issues medical cannabis prescriptions (PT33) to patients and visitors in Thailand. All prescriptions are issued by licensed physicians affiliated with Wonderland Clinic, a registered medical facility with background in both Thai traditional medicine and contemporary clinical practice.

Consultations are available daily from 10:00 AM to 2:00 AM — hours that align with dispensary operating schedules across the city.

One practical feature for travelers is that the online consultation can be completed before arriving in Thailand. A PT33 prescription can be obtained in advance through ThaiCannaMed.com, which means it is possible to arrive with documentation already in place.

From observation at several Bangkok dispensaries, ThaiCannaMed has been introduced as the standard prescription pathway at OG Distribution partner locations — including Cloud Nine and Kush House — where the QR code and consultation instructions are displayed at the counter.

What PT33 Means Under Thai Law

Once issued, the prescription generates a medical card, and the PT33 document is sent directly to the patient via email. This ensures that patients always have access to an official copy of their prescription for verification when needed — whether at the dispensary counter, during a police check, or if questions arise on departure from Thailand.

Key parameters under the current framework:

This is why it functions as a point-of-sale document rather than a paper form.

What Purchasing Without a Prescription May Involve

Since June 2025, cannabis flower in Thailand has been classified as a Controlled Herb under health regulations, a classification that requires a physician-issued prescription for legal purchase and possession. It has been reported that purchasing or possessing cannabis without a valid PT33 may be subject to fines of up to 25,000 THB and potential detention of up to three months.

The Thai Ministry of Public Health has indicated that spot-check operations at dispensaries are part of ongoing compliance monitoring.

From observation, a gap remains between what the law requires and how some shops operate in practice. Many dispensaries continue selling without consistently verifying documentation. That gap, however, does not transfer legal protection to the buyer. What matters in a police check or border interaction is the documentation the individual carries — not what the shop chose to ask for at the point of sale.

One additional consideration for foreign visitors is the legal environment in their home country. In some countries, cannabis use abroad may carry implications under domestic law even when conducted legally in Thailand. Travelers are encouraged to check the regulations relevant to their country of residence before and after their visit.

2: The ThaiCannaMed Process — What It Looks Like in Practice

From personal experience completing the ThaiCannaMed consultation at Kush House on Sukhumvit Soi 22, the following is what the process involves from start to finish. Kush House is a cannabis dispensary located in the Sukhumvit area of Bangkok, close to Phrom Phong BTS station on the BTS Skytrain line.

Step 1: Scanning the QR Code at the Counter

At Kush House, the consultation begins at the counter. A ThaiCannaMed QR code is displayed at the point of entry. Scanning it opens the online consultation page directly on your phone.

Step 2: Online Health Questionnaire

The questionnaire is in English by default, with language switching available for multiple languages. The questions cover basic personal information and the reason for seeking medical cannabis — a standard intake process consistent with a medical consultation. Staff at the counter assist if any section is unclear. The form typically takes a few minutes to complete.

Step 3: Video Consultation with a Licensed Physician

After submitting the questionnaire, a video call connects to a physician from Wonderland Clinic. The doctor asks several follow-up questions based on the submitted responses. The consultation is brief. English is the primary language used; staff assistance with communication is available for those who need it.

Step 4: PT33 Issuance and Medical Card

After the video call, there is a waiting period of approximately ten minutes. The PT33 prescription is then issued, and the patient receives a medical card along with the prescription sent via email.

The card is valid for 30 days from the date of issue and is accepted at all ThaiCannaMed partner locations within the OG network. There is no need to repeat the consultation process at other participating dispensaries during that period.

3: How the Medical Card and Prescription System Works Across the OG Network

The medical card issued through ThaiCannaMed serves a function beyond the dispensary counter.From observation, three distinct uses have been confirmed.

At the Point of Sale

The card is presented at the dispensary counter to confirm prescription status before purchase. At all OG network locations, this is the standard verification step in the purchase process.

During a Police Check

If questioned while in possession of cannabis, patients can present the medical card together with the emailed PT33 prescription to demonstrate that the use is based on a valid medical authorization. If necessary, authorities can also contact the issuing provider directly for verification.

Patients are also able to keep a copy of the prescription on their phone for easy access when needed.

Network Portability Across OG Locations

Because the card is issued at the network level rather than by a single shop, it is accepted at every participating OG location for the duration of its 30-day validity period. Visiting Cloud Nine on one day and Kush House the next does not require a new prescription.

ThaiCannaMed and OG Distribution

From observation and publicly available information, ThaiCannaMed’s closest operational integration is with OG Canna / OG Distribution — the group behind Cloud Nine, Kush House, Mary Jane, Wonderland, Juicy Buds, and Lucky Luke’s. The physician network supporting the service is based at Wonderland Clinic, which sits within the OG brand family. (Source: ThaiCannaMed)

ThaiCannaMed also provides a white-label solution, meaning individual OG locations present the system under their own branding while running on the same underlying platform. The QR code panels at Cloud Nine and the counter-based consultation flow at Kush House reflect this integration.

ThaiCannaMed is not a third-party service that happens to be accepted at OG stores — it is the prescription infrastructure the OG network was built around. Within that network, the card functions as the standard, not an exception.

What ThaiCannaMed Provides in Practice

ThaiCannaMed is the mechanism through which Thailand’s medical cannabis prescription requirement can be met in a format designed for dispensary visits — including tourists who arrive with no prior knowledge of PT33 or how to obtain one.

From observation, the consultation process adds a brief step to the dispensary visit rather than a separate trip to a clinic. A same-day process produces documentation covering 30 days of purchases across multiple Bangkok locations. For travelers visiting more than one OG dispensary, or staying for an extended period, that coverage has practical value.

Thailand’s regulatory environment continues to shift. Enforcement patterns have changed since the June 2025 reclassification, and there is no reliable way to predict which locations or situations will be subject to checks on any given day. The prescription is the documentation that provides a basis for explanation when those situations arise.

Completing the consultation before purchasing, keeping the medical card and prescription accessible, and retaining it for the full duration of a stay reflect the intent of the current framework.
