Cannabis appears in Thai traditional medicine as an ingredient in named preparations. That history does not mean every cannabis product is a medicine, every shop is a clinic, or every symptom should be treated with cannabis. A patient needs to know who is responsible for care, what preparation is proposed and why.
This guide replaces our earlier roundup of dispensaries. That roundup blurred the distinction between budtenders and healthcare professionals and made unsupported claims about product purity. It did not provide enough information for a medical decision.
Start with the preparation, not the shop name
DTAM publishes information on traditional formulas containing cannabis. These are identifiable preparations with their own composition and context. They should not be treated as equivalent to an unnamed flower, oil or edible. DTAM information on cannabis-containing traditional preparations.
Ask for the preparation's full name, manufacturer or authorised source, ingredients, intended use and instructions. Where a practitioner prepares a formula for an individual, ask how that preparation and its directions will be documented. A translated nickname or a strain name alone may not identify the medicine.
Who is providing the assessment?
Thailand recognises several categories of professionals in the controlled-cannabis prescription framework, including Thai traditional and applied Thai traditional medicine practitioners. Their professional status and permitted scope matter. A staff member's familiarity with strains is not proof of prescribing authority. DTAM medical-cannabis establishment guidance.
Before an appointment, ask for the practitioner's name, professional category and a way to verify registration. Establish which clinic or licensed establishment is responsible for the service. If a shop arranges a consultation elsewhere, ask who conducts it and how you receive the result.
What a useful consultation should clarify
| Question | Information to leave with |
|---|---|
| What problem are we assessing? | A clear clinical question, rather than a general promise of wellness |
| Why this preparation? | An explanation relevant to your history and other treatment |
| What are the alternatives? | Other reasonable options, including no cannabis treatment |
| What could go wrong? | Relevant unwanted effects, interactions and precautions |
| How will we judge benefit? | A follow-up plan and meaningful goals |
| Who can I contact? | Instructions if symptoms worsen or a medicine problem occurs |
Bring a list of medicines and supplements, previous diagnoses and any prior reaction to cannabis. Tell the practitioner about pregnancy or breastfeeding and activities where impairment would be dangerous. Do not stop an existing medicine merely because a proposed treatment is traditional or herbal.
Separate traditional use from evidence of benefit
A record that a formula was used historically answers a historical question. Evidence that it helps a particular condition requires assessment of the actual preparation and outcomes. Research about isolated CBD, a THC-containing medicine or a different formula may not answer your question.
Ask whether the explanation is based on traditional practice, clinical studies, an individual assessment or a mixture of these. These sources of reasoning can be described honestly without calling all cannabis “medicinal.” Our medical cannabis history guide separates historical records from modern treatment evidence.
Check product records separately
Awards, genetics and imported nutrients do not establish that a product is free of contamination. A certificate of analysis needs to match the product or batch, identify the tests and show their limits. A supplier certificate and a laboratory report answer different questions.
Our cannabis sourcing guide explains the documents relevant to flower sources. A source record does not replace the clinical assessment or prove a treatment outcome.
For controlled flower, follow the applicable prescription and dispensing process. Read how to obtain a medical cannabis prescription for practical preparation before an assessment. Approval depends on the professional's decision, not on buying a consultation.
Revised 6 September 2026. This page now focuses on patient questions and documented preparations; the previous dispensary endorsements and purity guarantees have been withdrawn.
