PT28 reporting for cannabis dispensaries in Thailand is the monthly evidence trail showing how controlled cannabis flower was used or sold at a licensed premises. A PT28 total should never be created from memory at the end of the month. It must agree with the shop’s daily transactions, PT27 source and stock records, matching PT33 prescriptions and the physical flower remaining on site. The official DTAM guide for medical cannabis establishments requires monthly reporting within one month after the end of the relevant month.
This guide explains what PT28 records, how the forms connect, how to close the month and which mistakes create enforcement risk.
What Is PT28?
PT28 is the controlled-herb report recording cannabis flower used or sold at the licensed premises. For a dispensary, it documents flower leaving stock through reportable transactions. Licensed operators can access the official DTAM controlled-herb system using their licence details.
The purpose of PT28 reporting for cannabis dispensaries in Thailand is traceability. An inspector should be able to follow flower from its lawful source through stock, patient supply and the monthly report.
PT28 is not the patient’s prescription. It is also not a substitute for a stock ledger, receipt or licence. ThaiCannaMed’s detailed guide to PT28 and PT33 cannabis compliance explains the wider chain.
PT27, PT28 and PT33: Three Different Records
Owners often get into trouble when the three forms are treated as interchangeable.
Record | Main purpose | Practical question it answers |
PT27 | Records source and stock information | Where did the flower come from and what entered the premises? |
PT28 | Records use or sale by the licensee | What flower left stock, when and through which transaction? |
PT33 | Records the practitioner’s patient-specific prescription | What amount was medically authorised for this patient? |
The official PT33 form published in the Royal Gazette records the patient, clinical reason, daily amount, treatment days, total quantity and practitioner. A PT33 can cover no more than a 30-day treatment period.
Accurate PT28 reporting for cannabis dispensaries in Thailand connects these records without blurring their purposes. PT27 explains stock coming in. PT33 supports an authorised patient supply. PT28 records what the business did. A PT28 entry cannot make a sale compliant if no genuine PT33 existed first.
What Information Should Support a PT28 Entry?
Use the current official form and system. Each reportable movement needs retrievable evidence.
The supporting transaction file should establish:
- The date of the transaction.
- The patient or buyer identification required by the current form.
- The relevant PT33 and practitioner details for a patient supply.
- The cannabis flower product and actual quantity supplied.
- The corresponding reduction in stock.
- The receipt or internal transaction reference.
- Who checked and entered the information.
If ten grams were authorised but four supplied, record four. A promotion cannot exceed the practitioner’s authorisation.
The Monthly PT28 Reporting Deadline
Current DTAM guidance states that the licensee must submit monthly operational reports within one month after the end of the relevant month. That does not mean the business should wait until the final day.
A sensible process for PT28 reporting for cannabis dispensaries in Thailand uses three layers:
- Record each reportable transaction when it happens.
- Reconcile sales, prescriptions and stock at the end of each day or shift.
- Review and submit the completed monthly report before the deadline.
Late reconstruction creates missing details, duplicate entries and unexplained stock differences.
A Practical Month-End PT28 Workflow
1. Freeze the Reporting Period
Confirm the opening and closing dates and ensure later transactions are not accidentally included. Each licensed location should close its own reporting period even if a group uses central oversight.
2. Export or Assemble the Transaction List
Gather every reportable movement from the point-of-sale system, partner dashboard and daily controls. Check voids, returns and corrections.
3. Match Each Patient Sale to PT33
Verify the patient’s name and Thai ID or passport, practitioner details, issue date, treatment period and authorised amount. ThaiCannaMed’s PT33 prescription guide explains the fields staff should recognise.
For partners, the ThaiCannaMed telemedicine system can make consultation and prescription readiness visible. It does not permit the licensee to skip its own transaction checks or monthly report.
4. Reconcile PT27, PT28 and Physical Stock
Use a simple control calculation:
Opening stock + documented receipts − documented movements = expected closing stock
Compare the expected figure with the physical count. Investigate every difference. Do not invent a sale, prescription number or wastage entry merely to force the balance to match.
5. Review Exceptions
List missing documents, duplicates, unclear quantities, late entries and unexplained adjustments. Assign and resolve each item before submission.
6. Approve and Submit
The licensee or authorised responsible person should review the completed report, supporting totals and unresolved exceptions. Submit through the current official route and retain proof of submission.
7. Secure the Monthly File
Keep the final report, source records, transaction evidence, correction notes and submission confirmation together. DTAM’s current establishment guidance requires PT33 to remain at the dispensing premises for at least one year and accounts and supporting evidence to be retained for at least three years.
The Most Common PT28 Reporting Failures
Strong PT28 reporting for cannabis dispensaries in Thailand is usually defeated by ordinary habits.
Reporting the Prescribed Amount Instead of the Supplied Amount
PT33 sets the medical ceiling; PT28 must reflect the actual business movement. Those figures are not automatically identical.
Completing the Report Only at Month End
A monthly total without transaction-level evidence is fragile. Reporting should summarise daily controls, not excavate old receipts.
Using One Branch’s Records for Another
Each transaction belongs to the licensed premises where it occurred. Central software can support several locations, but it must preserve branch-level evidence.
Keeping PT28 Without Matching Stock Records
An apparently tidy PT28 report will not explain why the physical count differs from PT27 source records and recorded movements.
Treating Blank-Signed PT33 Forms as Evidence
In July 2026, DTAM reported a criminal complaint involving blank-signed PT33 forms allegedly completed later to support false PT28 reporting. A signature without a genuine medical assessment does not create a lawful prescription.
Corrections Must Leave a Trail
Corrections should preserve the original information, explain the change, identify who made it and retain supporting evidence.
For PT28 reporting for cannabis dispensaries in Thailand, staff should never overwrite a quantity simply because the physical count is different. First determine whether the cause was a data-entry error, an unrecorded movement, a duplicate, authorised wastage, loss or theft. Apply the correct process and escalate material discrepancies.
Enforcement Risk in 2026
Reporting is now a visible enforcement issue, not harmless back-office administration. Ministry of Public Health enforcement guidance published in June 2026 states that failing to prepare, retain or submit PT27 and PT28 reports, or submitting incomplete reports, can result in a 30-day licence suspension. Selling without PT33 can lead to a 90-day suspension, while false reporting and repeated breaches can expose the licence to revocation.
The 2026 DTAM establishment rules also make previous suspensions relevant to licence renewal. Accurate reporting therefore protects the business’s future.
What ThaiCannaMed Can and Cannot Do
ThaiCannaMed helps partner dispensaries connect patients with a licensed Thai Traditional Medicine (TTM) doctor through Wonderland Clinic and see the PT33 workflow before supply. Owners can review the dispensary partner programme for the current portal and onboarding process.
That support can reduce missing prescription information, but the licensee remains responsible for PT28 reporting for cannabis dispensaries in Thailand. ThaiCannaMed does not own the shop’s licence, stock, source records or transaction accuracy.
Frequently Asked Questions
Is PT28 the Same as PT33?
No. PT28 records use or sale by the licensed premises. PT33 is the authorised practitioner’s prescription for a named patient.
When Is PT28 Due?
For PT28 reporting for cannabis dispensaries in Thailand, current DTAM guidance requires submission within one month after the end of the relevant month. Confirm the procedure with DTAM in Bangkok or the Provincial Public Health Office outside Bangkok.
How Long Must Records Be Kept?
Keep PT33 at the dispensing premises for at least one year. Keep accounts and supporting inspection evidence for at least three years and available for inspection during operating hours.
Does a Zero-Sales Month Remove the Reporting Duty?
Do not assume that no sales means no filing. Follow the current official system and obtain instructions from the relevant licensing authority for nil activity.
Can a Partner Portal Submit Everything Automatically?
A portal can organise information, but the licensee must review the report, reconcile stock and ensure accuracy. It supports PT28 reporting for cannabis dispensaries in Thailand without replacing responsible oversight.
Make PT28 Part of Every Transaction
Reliable PT28 reporting for cannabis dispensaries in Thailand begins at the counter, not on the reporting deadline. Verify the PT33, record the quantity actually supplied, update stock, investigate differences and preserve the supporting evidence while the transaction is still fresh. Dispensary owners who want a clearer prescription pathway alongside those controls can apply to become a ThaiCannaMed partner, while retaining full responsibility for an accurate monthly submission.
