When cannabis customers without prescriptions enter a dispensary in Thailand, staff should pause the sale, explain the medical-access requirement clearly and direct the customer towards an independent assessment by an authorised Thai practitioner. Staff must not diagnose the customer, suggest symptoms, promise approval or supply cannabis flower before a valid PT33 has been issued. Dispensaries that need a structured referral route can learn about the ThaiCannaMed Partner Programme, but using a third-party system does not transfer the retailer’s legal responsibilities.
The customer may be surprised or carrying medical paperwork from another country. Neither circumstance turns a retail employee into a clinician or removes the dispensary’s duty.
Quick answer: what should a dispensary do?
For cannabis customers without prescriptions, the correct sequence is:
- Stop the transaction before cannabis flower is supplied.
- Explain that Thailand now treats access as a medical process.
- Ask whether the customer already holds a current, usable Thai PT33.
- If not, offer a neutral route to an independent authorised practitioner.
- Keep retail staff out of diagnosis and prescribing decisions.
- Wait for the practitioner’s decision and verify any resulting documentation.
- Complete the sale only when the applicable requirements have been met.
- Record the transaction and maintain the shop’s required documentation.

Why a customer’s request is not enough
Thailand’s present framework is centred on medical use. A customer saying that cannabis helps them sleep, manage discomfort or relax does not itself authorise a sale. A social-media post, an old receipt, a foreign cannabis card or a prescription issued outside Thailand should not be treated as a substitute for the required Thai process.
For cannabis customers without prescriptions, the safest staff response is factual and calm: the shop cannot make a clinical decision, but it can explain how the customer may seek an assessment from an authorised practitioner. That protects the boundary between retail service and healthcare.
What dispensary staff can and cannot do
Staff can
- Explain the shop’s sales procedure in plain language.
- State that a valid PT33 is required before the relevant purchase can proceed.
- Provide access to an independent consultation route.
- Help with non-clinical technical steps, such as locating a QR code or opening a portal.
- Check that required documentation is present and current before completing a sale.
- Explain product labels, prices and factual retail information after authorisation.
- Follow the dispensary’s record-keeping and reporting procedures.
Staff cannot
- Diagnose a condition or decide that cannabis is medically appropriate.
- Tell a customer which symptoms to select or what to say to a practitioner.
- Guarantee that the customer will receive a prescription.
- Pressure or influence the practitioner’s independent decision.
- Change the condition, quantity, duration or other details on a PT33.
- Advise a customer to stop or alter prescribed medication.
- Supply cannabis before the required process is complete.
These limits should appear in a written staff procedure that employees can follow during a busy shift.
A seven-step workflow for cannabis customers without prescriptions
1. Identify the missing document
Ask: “Do you currently have a valid Thai PT33 for this purchase?” Do not interrogate the customer about medical details at the counter.
2. Explain the rule without giving legal theatre
A clear explanation is enough: cannabis flower is controlled for medical use, and the shop cannot proceed without the required prescription. The ThaiCannaMed patient guide explains the consultation pathway.
3. Do not coach the assessment
Employees must not tell cannabis customers without prescriptions which complaint may be accepted. The customer should provide truthful information, and the practitioner must assess it independently.
No prescription is guaranteed. A practitioner may approve a PT33, request more information, recommend a different course or decline to prescribe.
4. Provide a genuine practitioner route
A dispensary may direct the customer to an authorised practitioner or make an independent telemedicine pathway available in store. The consultation belongs to the practitioner, not the retailer.
Through ThaiCannaMed, a first consultation costs THB 600 and a renewal costs THB 400. Where advance intake has been completed, the practitioner consultation may take approximately one to five minutes. The full journey—including intake, connection, assessment and documentation—generally takes approximately five to fifteen minutes. These are different timings, not promises, and an individual case may take longer.
5. Wait for the clinical decision
A consultation link, QR code or customer record is not approval. Cannabis customers without prescriptions cannot complete the transaction unless the independent practitioner issues the appropriate PT33.
6. Verify before supplying
Staff should check the prescription’s validity and ensure that the proposed transaction matches it. A PT33 is generally valid for up to 30 days, but the authorised practitioner determines what is clinically appropriate. Retail staff cannot extend, rewrite or reinterpret it.
7. Complete the shop’s records
Prescription access is only one part of dispensary compliance. The licensee remains responsible for the shop’s licence conditions, sourcing, sales records, PT27 and PT28 processes, document retention and any reporting required by the authorities. DTAM’s controlled-herb licensing portal should be monitored alongside official regulatory notices and operating guidance.
What if the customer is a tourist?
Tourists follow the same process. A passport or foreign cannabis card does not remove the need for the applicable Thai documentation. Staff cannot convert foreign paperwork into a Thai prescription or promise approval.
The customer should also be told that receiving a PT33 does not create permission to export cannabis, carry it across an international border or ignore other restrictions. The prescription supports the approved medical use described by the practitioner; it is not a travel permit.

What if the customer is pregnant or breastfeeding?
Do not proceed with a retail sale. Escalate the situation according to the dispensary’s written procedure and direct the individual towards an appropriate healthcare professional. Staff must not attempt to weigh risks, recommend a product or present cannabis as safe during pregnancy or breastfeeding. The World Health Organization’s cannabis health information provides general public-health context, but an individual medical decision belongs to a qualified practitioner.
Why the procedure should be documented
Handling cannabis customers without prescriptions consistently is easier when every employee follows the same checklist. A useful standard operating procedure should cover:
- the wording used to pause a transaction;
- acceptable evidence and verification steps;
- the separation between retail and clinical activity;
- privacy when customers enter medical information;
- escalation to a manager when documents appear incomplete;
- refusal of sale when the required conditions are not met;
- transaction records and the shop’s PT27/PT28 responsibilities; and
- regular checks for regulatory updates.
Managers should test the procedure through short role-play scenarios so the correct response becomes routine.
Where ThaiCannaMed and Green Network fit
ThaiCannaMed can give partner dispensaries a structured route through which a customer connects with an independent authorised practitioner. Participating Green Network dispensaries can support this pathway in Bangkok and Phuket, the two areas currently confirmed for Green Network coverage.
That support does not make ThaiCannaMed the licensee, guarantee a prescription or make every later transaction automatically compliant. The dispensary retains its responsibilities. The practitioner retains clinical control. The customer must provide accurate information. Each party has a different role.
For shops that regularly receive cannabis customers without prescriptions, a clear pathway can reduce confusion at the counter and help staff maintain the correct boundary. Dispensaries can review how the Green Network supports prescription-based access and apply through the Partner Programme if the model fits their operation.
Frequently asked questions
Can a dispensary sell first and arrange the PT33 afterwards?
No. The required medical process and documentation must come before the relevant sale, not be reconstructed afterwards.
Can staff help a customer choose a medical condition?
No. Staff must not diagnose, suggest symptoms or coach answers. The customer should speak honestly with the practitioner.
Is the practitioner required to approve every customer?
No. Approval is never guaranteed. The practitioner makes an independent decision based on the individual assessment.
Does Green Network membership remove the shop’s responsibility?
No. It supplies a structured access pathway, but the licensee remains responsible for its retail operation, documentation and compliance.
Can a foreign prescription replace a Thai PT33?
No. Foreign documentation may provide background for a practitioner, but it does not replace the applicable Thai process.
The correct response is simple, but the boundaries matter
The right way to handle cannabis customers without prescriptions is to pause the sale, explain the requirement and provide access to an independent assessment without interfering in it. Only after the correct documentation has been issued and verified should the dispensary consider completing the transaction. A written workflow, trained staff and a genuine separation between retail and clinical decisions make that process clearer for the customer and safer for the business.
