For licensed cannabis operators, understanding PT27, PT28, and PT29 in Thailand is an important part of maintaining accurate records for controlled cannabis flower. Each form serves a different purpose, and the information recorded must correspond with the business’s activities, supporting documents and physical stock.
The Department of Thai Traditional and Alternative Medicine reporting system provides online access for reports from PT27 through PT32. Where controlled cannabis flower is supplied to a patient, the business records must also connect with a valid PT33 cannabis prescription.
This article is specifically for dispensary owners, cannabis-business operators and licence holders. It explains the individual purposes of PT27, PT28 and PT29 without confusing statutory reporting obligations with ThaiCannaMed’s dispensary partner services. A clinic, network or software provider may support part of a workflow, but the licence holder remains responsible for the business’s records and decisions.
PT27, PT28 and PT29 Serve Different Purposes
Businesses researching PT27, PT28, and PT29 in Thailand may encounter descriptions that group all three forms together as monthly compliance paperwork. Although they belong to the same reporting framework, they are not interchangeable.
| Form | Main purpose |
|---|---|
| PT27 | Reports the source and quantity of controlled cannabis flower stored or held |
| PT28 | Reports the use or supply of controlled cannabis flower |
| PT29 | Reports qualifying commercial processing and sales of resulting products |
| PT33 | Records a prescription issued to a named patient by an authorised practitioner |
PT33 is not a business stock report. It records a medical decision following a genuine patient assessment. PT33 does not replace PT27, PT28 or PT29, and completing a business report cannot retrospectively authorise an improper transaction.
What Does PT27 Record?
PT27 records the source and quantity of controlled cannabis flower stored or held by the licence holder. It establishes where the flower came from, when it was obtained and how much the business retains.
Within PT27, PT28, and PT29 in Thailand, PT27 represents the incoming and holding side of the stock trail. The information should be supported by supplier details, applicable licence information, invoices, delivery documents, internal stock receipts and the quantity physically present.
The figures recorded in PT27 should agree with the business’s inventory. If the documented quantity and physical stock do not match, the licence holder should investigate and record the reason. Changing a figure simply to make the report balance weakens the entire evidence trail.
Recording incoming stock when it arrives is a practical way to reduce missing information. However, an organised PT27 record does not guarantee that the business has met every requirement applying to its licence.
What Does PT28 Record?
PT28 records how controlled cannabis flower is used or supplied. Depending on the transaction, it may include the date, buyer’s name, Thai identification number or passport number, date of birth, relevant licence details, purpose and dry-flower quantity.
For dispensaries, PT28 is where PT27, PT28, and PT29 in Thailand connects directly with patient dispensing. Before supplying controlled flower, the business must verify that:
the patient has an active Thai PT33;
the patient’s identity matches the prescription;
an authorised Thai-licensed practitioner issued it;
the treatment period remains valid; and
the supply remains within the authorised quantity.
A foreign cannabis card, overseas prescription or foreign doctor’s letter does not replace a Thai PT33. Patients who need to begin the Thai medical process should use the current ThaiCannaMed patient consultation route.
Dispensary staff cannot diagnose a customer, prescribe cannabis, coach someone to report particular symptoms, alter a PT33 or advise a patient to stop taking medication. Those decisions belong to an authorised practitioner.
PT28 entries should agree with receipts, retained prescription evidence and inventory reductions. If a quantity is recorded as supplied, the stock records must show the corresponding movement.
When Does PT29 Apply?
PT29 concerns controlled cannabis flower processed into another commercial product and the sale of the resulting product. It records information such as the processing date, quantity of flower used, product created, finished quantity, buyer details and quantity sold.
This is one of the most frequently misunderstood parts of PT27, PT28, and PT29 in Thailand. PT29 should not be described as a universal retail report that every dispensary uses in precisely the same way. Its application depends on the business’s licence and actual processing activities.
The instructions associated with PT29 distinguish products produced through processing from cannabis flower that remains clearly recognisable as flower. They give pressed or rolled flower as examples of material that may remain visibly identifiable as cannabis flower rather than becoming another processed product for PT29 reporting.
Businesses should not classify their products from an online summary alone. Where the correct treatment is uncertain, the licence holder should confirm it with DTAM or the relevant provincial public health authority.
Where PT29 applies, records should show:
the quantity of flower removed from stock;
the processing date;
the product created;
the number of finished units;
any properly recorded difference or waste; and
the processed products subsequently sold.
How the Three Reports Work Together
The practical value of PT27, PT28, and PT29 in Thailand lies in reconciliation.
PT27 establishes the source and quantity of flower held. PT28 records controlled flower used or supplied. PT29 records flower entering qualifying processing and the sale of resulting products.
The records should form a continuous trail from an authorised source to physical stock and then to supply or processing. A quantity reported through PT28 should correspond with a reduction in inventory. Flower entering a relevant processing activity should connect with the applicable PT29 output records.
Supplier evidence, receipts, inventory, PT27, PT28, applicable PT29 records and physical stock should tell the same story. A completed form cannot resolve an unexplained stock shortage or make an unsupported transaction acceptable.
Software may help organise entries, but it cannot declare a business compliant. ThaiCannaMed and the Green Network do not assume the licence holder’s reporting responsibilities.
How PT33 Connects to PT28
PT33 is the official prescription for controlled cannabis flower issued to a named patient after a genuine medical assessment. The Royal Thai Government Gazette PT33 form connects the patient, practitioner, treatment directions, authorised quantity and treatment period.
When a dispensary supplies flower to a patient, PT33 provides the medical authority for that individual supply. PT28 records the corresponding business-side movement. This is the central relationship between PT33 and PT27, PT28, and PT29 in Thailand.
A PT33 may cover no more than 30 days. ThaiCannaMed’s current operating information generally applies a maximum of 30 grams within 30 days. Up to 60 grams may be considered only for severe cases, at the practitioner’s discretion and with supporting evidence. The practitioner may prescribe less, and the dispensary cannot increase the authorised amount.
Patients must be at least 20 years old. Controlled cannabis flower should not be supplied during pregnancy or breastfeeding. ThaiCannaMed’s confirmed condition information currently includes chronic pain, insomnia, migraine, loss of appetite and Parkinson’s disease. These conditions may be assessed, but none guarantees approval.
PT33 records should be retained at the premises for at least one year. Accounts and supporting inspection evidence should be retained for at least three years. Patient identity and medical information must be stored securely and handled in accordance with Thailand’s personal-data requirements.
Reporting Frequency and Official Access
The instructions accompanying PT27, PT28 and PT29 require applicable reports at least once per month by the final day of the month. They also allow information to be entered through the official online system daily.
Operators should check the current DTAM reporting service and confirm the requirements applying to their licence. An old downloaded form, another dispensary’s procedures or a general online article should not replace current instructions from the responsible authority.
Record-Keeping Checks for Licence Holders
An internal review of PT27, PT28, and PT29 in Thailand should establish whether:
incoming flower has a documented and authorised source;
quantities received agree with supplier records;
physical stock agrees with the recorded inventory;
every supply has the required transaction evidence;
patient identity and PT33 validity were checked before dispensing;
no more than the authorised quantity was supplied;
applicable processing inputs and outputs remain traceable;
PT33 and inspection records are retained for the required periods;
sensitive patient information is stored securely; and
staff understand the limits of their role.
The forms should be reviewed as connected records rather than isolated documents. A report can appear complete while the supplier evidence, receipt, prescription or physical stock shows something different.
Common Reporting Mistakes
Businesses managing PT27, PT28, and PT29 in Thailand should avoid recording transactions late, entering quantities that do not match receipts, retaining incomplete patient evidence, leaving discrepancies unexplained or assuming another organisation is responsible.
They should also avoid copying another dispensary’s procedures without checking whether its licence and activities are comparable.
Most importantly, reporting does not authorise a transaction after the event. Prescription verification, identity matching and quantity control must occur before controlled cannabis flower is supplied.
Frequently Asked Questions
Are PT27, PT28 and PT29 the same as PT33?
No. PT27, PT28 and PT29 perform business-side reporting functions involving stock, use, supply and processing. PT33 is a patient prescription issued by an authorised practitioner after a genuine assessment.
Does every cannabis dispensary need to submit PT29?
Not automatically. PT29 relates to qualifying processing of controlled cannabis flower and sales of resulting products. Its application depends on the licence and the business’s actual activities.
Can ThaiCannaMed complete these obligations for a dispensary?
No. ThaiCannaMed may support a medical-consultation workflow, but the licence holder remains responsible for reporting, stock reconciliation, record retention and dispensing decisions.
Where are PT27, PT28 and PT29 submitted?
DTAM provides an online reporting system covering PT27 through PT32. Licence holders should confirm the current process with DTAM or their provincial public health authority.
Final Thoughts
Understanding PT27, PT28, and PT29 in Thailand means recognising three connected but different reporting functions. PT27 records the source and quantity of controlled flower held. PT28 records its use or supply. PT29 covers qualifying processing and sales of resulting products.
The reports should reconcile with supplier evidence, physical stock, transaction documents and valid PT33 records where patient dispensing is involved. ThaiCannaMed may support the medical-access process, but responsibility remains with the business and its licence holder.
For cannabis operators, PT27, PT28, and PT29 in Thailand should be maintained as connected, truthful and retrievable evidence rather than isolated paperwork.
