Cannabis in Koh Samui 2026 — Dispensaries, Clinics & Medical Access

Koh Samui, Thailand’s second-largest island, has developed a well-established cannabis scene catering primarily to the steady stream of international tourists who visit year-round. With approximately 100 dispensaries and 10 clinics, the island offers solid coverage across its main tourist areas. The cannabis market here is distinctly tourist-oriented, with most shops located in the beach resort zones of Chaweng, Lamai, and Bophut’s Fisherman’s Village.

Following the June 2025 regulatory changes, Koh Samui’s dispensaries have adapted to the PT 33 prescription requirement with relative ease. The island’s 10 clinics are strategically located in the main tourist centers, and many dispensaries maintain referral relationships with nearby clinics. Being an island, Koh Samui’s cannabis supply is imported from the mainland, which can occasionally affect availability and pricing compared to cities with direct farm access.

The atmosphere in Koh Samui’s cannabis shops mirrors the island’s overall vibe — relaxed, friendly, and vacation-oriented. Many dispensaries double as chill-out spaces where visitors can enjoy their purchases in a comfortable setting, often with ocean views or tropical garden surroundings.

Getting a PT 33 Prescription in Koh Samui

Koh Samui has 10 clinics offering PT 33 consultations, primarily concentrated in Chaweng and Lamai. The clinics on the island are accustomed to serving international visitors and most have English-speaking doctors or translators available. Chaweng’s clinics along the main beach road are the most accessible for walk-ins, while Lamai and Bophut each have a few options. Consultation fees typically range from 400-800 THB. Due to the limited number of clinics, it is advisable to visit during morning hours to avoid potential waits, especially during peak season (December-February).

What to Know Before You Visit

• Koh Samui is a compact island but getting around requires transport. Most visitors rent scooters, but be aware that driving under the influence of cannabis is illegal in Thailand. Use the island’s songthaew (shared taxi) service or private taxis instead.
• Prices on Koh Samui tend to be 10-20% higher than mainland cities due to transport costs. Premium strains can be particularly marked up during peak tourist season.
• If you are island-hopping to Koh Phangan (a 30-minute ferry ride), your PT 33 prescription from Koh Samui is valid there as well.
