Cannabis in Koh Lanta 2026 — Dispensaries, Farms & Medical Clinic

Koh Lanta is one of the Andaman Sea’s most laid-back islands and a growing favorite among digital nomads, long-stay travelers, and anyone who wants a quieter alternative to Phuket or Krabi. Part of Krabi province, the island has a permanent population of around 30,000 and a cannabis scene that punches above its weight — 29 dispensaries, 2 farms, and 1 medical cannabis clinic as of March 2026, totaling 32 cannabis-related listings.

Unlike the party-fueled markets of Patong or Haad Rin, Koh Lanta’s cannabis culture mirrors the island itself: relaxed, community-oriented, and spread along the west coast road that connects the ferry pier at Sala Dan to the quiet bays of the south. The island draws a mix of families, couples, remote workers, and backpackers, and its dispensaries reflect this diversity — from beachfront weed cafes to farm-to-counter operations growing their own supply.

The June 2025 regulatory changes brought the PT 33 prescription requirement to Koh Lanta, and the island’s single dedicated clinic handles consultations efficiently. With most dispensaries clustered along the main road between Sala Dan and Kantiang Bay, finding cannabis on Koh Lanta is straightforward once you have your prescription in hand.

Best Cannabis Dispensaries in Koh Lanta

Koh Lanta’s dispensary scene is competitive and well-reviewed. Here are the top-rated shops based on Google reviews.

Highest-Rated Dispensaries

FLY HOUSE Koh Lanta leads the island with 265 Google reviews and a 4.9-star rating. This combined cannabis and coffee shop has become a go-to for visitors looking for quality flower in a relaxed cafe setting.

Cannabis Bar and Restaurant takes a different approach, combining a full food menu with cannabis retail. With 207 reviews and a 4.4-star rating, it is a popular social spot — though the lower rating suggests the food-and-cannabis combo does not work perfectly for everyone.

Lanta Highland Weed Cafe (4.8 stars, 118 reviews) offers an elevated setting with views, while Lanta Kush (5.0 stars, 78 reviews) and GURU 420 Dispensary (5.0 stars, 72 reviews) maintain perfect ratings with loyal followings.

Weedology Cannabis Culture rounds out the top tier with a 4.9-star rating from 117 reviews and a second location on the island — a sign of strong local demand.

Chain Operations

Several cannabis brands operate multiple locations on Koh Lanta, offering consistency for visitors who want a reliable experience:

• High Siam — High Siam Koh Lanta (4.9 stars, 199 reviews) is part of the High Siam chain that operates across multiple Thai islands. The brand is known for consistent quality and knowledgeable staff.
• Weedology — Weedology Cannabis Culture runs two locations on Koh Lanta, giving the island broader coverage from a single trusted brand.
• Babylon Ink — This brand also operates two locations on the island, combining cannabis retail with the tattoo culture that is common on Thai islands.

Budget Options

Koh Lanta is not the cheapest island for cannabis — being a tourist destination in the Andaman Sea means prices carry a markup over mainland cities. However, competition among 29 dispensaries keeps prices more reasonable than Phuket. Look for shops further south along the main road past Klong Nin, where lower foot traffic often translates to better deals. Some dispensaries offer happy-hour discounts during afternoon hours or bulk pricing on larger purchases.

Area Breakdown

Koh Lanta’s dispensaries are spread along the west coast road that runs the length of the island from north to south. Here is what to expect in each area:

• Sala Dan (North / Ferry Pier) — The first area you reach after the ferry. Sala Dan village has the highest concentration of dispensaries, shops, and restaurants on the island. This is where most day-one purchases happen, and competition keeps prices competitive. Convenient if you want to grab your cannabis immediately after arriving.
• Klong Dao Beach — The island’s longest and most family-friendly beach, just south of Sala Dan. Several dispensaries serve the resort crowd here. Expect a slightly more upscale selection with higher prices than Sala Dan.
• Phra Ae (Long Beach) — Popular with backpackers and mid-range travelers, Long Beach has a solid cluster of dispensaries including some of the island’s best-reviewed shops. The social scene here is active, with beach bars and restaurants where cannabis-friendly attitudes prevail.
• Klong Nin — A quieter stretch in the middle of the island with a handful of dispensaries. Klong Nin attracts longer-stay visitors and digital nomads who appreciate the balance between accessibility and peace. Good value can be found here.
• Kantiang Bay — The southern bay is home to fewer dispensaries but a more secluded atmosphere. If you are staying at one of the boutique resorts in this area, check whether your dispensary of choice offers delivery.
• Old Town (Lanta Old Town) — On the east coast, the historic Old Town is a charming area of stilted houses and seafood restaurants. It has very few dispensaries — most visitors make their purchases on the west coast and bring them over. Worth visiting for the atmosphere and food regardless.

Cannabis Farms in Koh Lanta

Koh Lanta has two cannabis farms, offering visitors a chance to see island-grown cannabis up close.

Hemp Zone Thailand Farm & Shop is the standout — with 67 Google reviews and a perfect 5.0-star rating, this combined farm and retail shop lets you buy flower grown on-site. The farm-to-counter model means fresher product and the ability to see exactly where your cannabis comes from. Hemp Zone is worth a visit even if you do not plan to buy, as the farm tour gives insight into tropical cannabis cultivation.

Cannabis Super Jack Farm is a smaller operation with just 3 reviews at 4.0 stars. It is less established as a visitor destination but may appeal to enthusiasts interested in seeing a different growing operation.

Getting a PT 33 Prescription in Koh Lanta

Under the June 2025 Cannabis Act, a PT 33 prescription is required to purchase cannabis from any licensed dispensary in Thailand. Koh Lanta has one dedicated medical cannabis clinic:

Cloud 420 Medical Cannabis Clinic — 121 Google reviews, 5.0-star rating. This is the island’s go-to for PT 33 consultations. The clinic has built a strong reputation with visitors, and the perfect rating across 121 reviews suggests a smooth, professional process. English-speaking staff are available.

Because Koh Lanta has only one clinic, plan accordingly:

• Visit early in the day — Walk-in waits can increase during high season (November-April), especially in the morning when ferry arrivals peak.
• Get your PT 33 in Krabi first — If you are passing through Krabi Town or Ao Nang before catching the ferry, consider getting your prescription on the mainland where more clinics are available. Your PT 33 is valid nationwide.
• Telehealth options — Some dispensaries can arrange remote consultations with licensed physicians. Ask at the counter if the clinic is busy.

A standard PT 33 consultation on Koh Lanta costs approximately 400-700 THB.

Koh Lanta Cannabis Prices (March 2026)

Grade	Price Range (THB/gram)	Notes
Budget	100–180	Basic strains, available at smaller shops
Mid-range	180–350	Quality hybrid and imported strains
Premium	350–600	Top-shelf exotic strains at shops like FLY HOUSE and High Siam
Farm-direct	120–250	Available at Hemp Zone Farm & Shop

Koh Lanta prices are generally lower than Phuket but higher than mainland cities like Krabi Town or Bangkok. The island markup reflects transport costs and tourist demand. Farm-direct purchases at Hemp Zone offer the best value for quality product.

How to Get to Koh Lanta

• Ferry from Krabi — The most common route. Ferries and speedboats depart from Krabi’s passenger pier to Sala Dan pier on Koh Lanta’s north end. The journey takes 1.5-2 hours depending on the vessel. High-season ferries run multiple times daily; low-season service is reduced.
• Minivan from Krabi Airport — Shared minivans run directly from Krabi Airport to Koh Lanta, including the short vehicle ferry crossing between the mainland and the island. The journey takes approximately 2-2.5 hours and costs 400-600 THB. Private transfers are also available.
• Vehicle ferry — If you are driving or riding a motorbike from the mainland, two short vehicle ferry crossings connect Koh Lanta to the mainland via Koh Lanta Noi. These run frequently throughout the day.
• From Phuket — Joint ferry-minivan services connect Phuket to Koh Lanta in approximately 4-5 hours during high season.

What to Know Before You Visit

• Rainy season closures — Koh Lanta’s low season runs from May through October, with the heaviest rains in September and October. During this period, some dispensaries reduce hours or close temporarily. The island does not shut down entirely, but selection and availability are reduced. If visiting during low season, stick to the Sala Dan and Klong Dao areas where shops are most likely to remain open.
• Motorbike safety — Most visitors get around Koh Lanta by motorbike. The main west coast road is generally in good condition, but side roads to beaches and viewpoints can be steep and unpaved. Do not ride under the influence of cannabis — this is both illegal and genuinely dangerous on the island’s hilly terrain.
• Delivery options — Several dispensaries offer delivery service across the island. This is particularly useful if you are staying in Kantiang Bay or other southern areas far from the main dispensary clusters. Ask your chosen shop about delivery range and minimum orders.
• Your PT 33 works everywhere — If you already have a valid PT 33 prescription from Krabi, Phuket, Bangkok, or any other Thai city, it works on Koh Lanta. No need to visit the local clinic again.
• Island-hopping note — Koh Lanta is a common stop on Andaman island-hopping routes that include Koh Phi Phi, Koh Ngai, and Koh Mook. Cannabis options on these smaller islands are extremely limited — stock up on Koh Lanta before heading to smaller destinations.
