Before You Visit
Walk-in availability is not confirmed in our data, so call ahead. The clinic does not accept insurance; plan to pay the consultation fee yourself. Once you hold a PT 33, any licensed outlet on the island can dispense against it for the 30 days it is valid, and a shop that offers to sell without one is breaking the law.
PT 33 Prescription Note
Since 26 June 2025, cannabis flower in Thailand is a controlled herb and may only be sold against a PT 33 prescription (ใบสั่งยา ปท. 33) from an authorised practitioner. Recreational sale is illegal, whatever a shop’s signage says, and a legitimate outlet will ask for your prescription before selling flower. CBD products at or below 0.2% THC are the only cannabis products sold without one. Call ahead to confirm a certified practitioner is on duty, and bring your passport or Thai ID. Our PT 33 prescription guide explains the consultation. For other outlets nearby, see cannabis clinics and dispensaries in Koh Lanta.
