Is Buprenorphine legal in Thailand?
- Legal status
- Buprenorphine is a controlled opioid under Thailand's Narcotics Code B.E. 2564 (2021) — a lighter tier than methadone — but it is NOT legally available (registered or dispensed) domestically; methadone is the sole agonist OST medicine in Thai clinics.
- Consequences if caught
- Unauthorised possession or supply of a controlled narcotic is an offence.
- If prescribed or medical
- Not dispensed domestically; opioid-substitution treatment in Thailand is methadone-based through public health centres.
- Documentation
- A traveller may carry up to 30 daily doses of prescribed buprenorphine with a doctor's letter; confirm with the Thai FDA.
