Koh Samui Cannabis Guide — Buying, Tiers & OG Lab

Quick answer: Adults 20+ can buy cannabis on Koh Samui from a licensed dispensary. OG Lab is a licensed hydroponic farm and shop in Taling Ngam, on the sunset side of the island. The live menu shows current strains and tier prices: the per-gram price drops at 5G+ and 20G+. Buying is in the shop. Do not smoke in public.

Who this guide is for

People land on this page with three different jobs.

Some smoke often and care about cleanliness, how the flower was cured, and whether the price per gram gets better when they buy more than a single gram. Some are on Koh Samui for a week and want a legal shop with a real address, not a rumour from a bar. A smaller group owns a licensed dispensary and needs a farm that can supply after lab tests. This page is for the first two. Shop owners should use wholesale.

We wrote it from the counter and the grow rooms, not from a list of search phrases. If a sentence does not help you decide where to go or what to buy, it does not belong here.

Buying in a licensed shop

Koh Samui has plenty of places that sell cannabis. The useful difference is whether the shop is licensed, whether you can see where the flower came from, and whether the price on the board matches the jar in your hand.

OG Lab is both the farm and the dispensary. The plants are grown on site in Taling Ngam, cured and stored by us, and sold in the same place. That is the opposite of a shelf filled with bags from somewhere else on the island. When you ask who grew a jar, the answer is the team in the rooms behind the glass, not a supplier we met once.

We have stayed open through the years when the rules in Thailand kept moving. The practical result for a guest is simple: we sell to adults, we follow the current law, and we do not treat the shop like a bar. It is a calm counter. You can take your time, ask what a strain smells like, and leave with something we would smoke ourselves. If a batch is not good enough for the people who grew it, it does not go on the menu.

Before you drive, open the full menu. It is the same list we sell from, with live prices. The page is built for a phone in the passenger seat as much as for a laptop at the hotel. If a strain is gone, it should not still be sitting there as a ghost price.

A few things we will not dress up as a service:

• We do not deliver.

• We do not ship flower off the island or out of Thailand.

• We do not sell “bulk” to someone who wants to resell without a licence.

• We do not publish a second, secret price list. The tiers on the menu are the prices.

If you want the longer version of how a visit to the counter works, read buying cannabis in Koh Samui. The short version is below.

How to read the menu

Each row is a strain. Colour marks the type: hybrid, sativa, or indica. A small mark means we grew it on the farm. Parents, flavour, and the feeling of the smoke sit under the name when we have something honest to say. A THC figure is a lab number for that batch, not a promise that you will feel a certain way.

Prices run in columns. The header shows the amount each column is for. You will usually see a single piece or a single gram, then a 5G+ column and a 20G+ column. The number in a heavier column is the price per gram once you reach that amount, not a flat fee for the whole bag. Read the header before you compare two rows. A cheap 1G price and a cheap 20G+ price are different decisions.

Farm-grown does not mean every jar is the same plant. We phenohunt. Some flower is loud and sweet, some is heavier, some is the one regulars ask for by name. If you already know what you like, say so. If you do not, start with smell. The jar is a better guide than a paragraph on a website.

Storage matters as much as the grow. Flower sits in conditions we control, then gets weighed and packed by hand when you buy it. That is why we would rather you pick it up here than have it ride around the island in a plastic bag for a day.

Larger amounts and tier prices

A lot of our guests do not buy one gram. They drive in from Chaweng, Lamai, or a villa on the west coast, stock up, and do not want to repeat the trip every evening. The menu is built for that. As the amount goes up, the price per gram goes down. The steps you will use most are 5G+ and 20G+.

Think of it the way you think of a shop outside town: you come once, you buy what you actually need, and the price respects the volume. It is still a retail sale across the counter, for personal use, to an adult. It is not a wholesale contract, and it is not a delivery.

What to do in practice:

1. Open the menu and note two or three strains, not ten.
2. Check the 5G+ and 20G+ columns for those rows, not only the first price.
3. Come to Taling Ngam during opening hours, 11:00–20:00.
4. Tell us the amount. We weigh it on jeweller’s scales and pack it in the climate-controlled room.

If you are deciding whether the drive is worth it, the FAQ Do you sell larger quantities at OG Lab? answers the policy in one screen. The article Buying cannabis in Koh Samui — retail and tiers walks through the same idea with a little more room.

We do not take reservations for a specific jar through this page. Stock moves. The menu is the reservation: if it is listed when you leave the hotel, ask for it when you arrive, and we will tell you honestly if the last of it went out an hour ago.

Getting to OG Lab

The shop is in Taling Ngam, on the west coast. Chaweng, where most visitors stay, is on the other side of the island. That sounds far until you drive it. The ring road is the trip.

Guests from Chaweng often make a loop of it. South or west along the ring road, a stop at the farm, then sunset near Nathon, which is the better side of the island for the evening light. Some people do this more than once in a week. It is a more interesting hour than sitting in traffic on the Chaweng strip looking for a shop with no parking.

Parking at OG Lab is dedicated and, in ordinary weeks, actually free when you arrive: 10 bikes and 6 cars. You do not have to hunt for a verge. If you are on a scooter from Lamai, you are here before a long playlist ends.

Hours are 11:00–20:00, every day. The phone on the door and on About is +66 98 204 0757. The pin we give guests is Google Maps. For the drive itself, Taling Ngam from Chaweng is the note we would send a friend, and How do I get to OG Lab? is the short form.

Nathon and Lamai are close enough that the farm is a normal errand, not an expedition. If you are staying on the sunset side already, you are in the neighbourhood.

Tourists and Thai law

If you are visiting Thailand, the rule that matters in daily life is smaller than the argument online. You need to be 20 or older. You buy from a licensed shop. You do not smoke on the beach, on the street, or in a bar because it is a public place. What you bought stays for private use. This page is not legal advice and not medical advice. If a rule is unclear to you, ask before you assume a photo from last year still describes this month.

A licensed shop should be able to tell you that the flower was tested. We do that before it is sold. You should also see a price before you pay, including the tier if you are buying more than a gram. If a place cannot show you either, keep walking. There are enough licensed counters on Samui that you do not need a stranger’s “trust me”.

Edibles and drinks, when they are on a menu, follow the same age rule and the same ban on public use. Read the label. Do not treat a packaged product as weaker or stronger than flower because it looks like a sweet. If you are unsure, buy the flower you can see and smell.

Carry yourself the way you would in any other country with a new rulebook: quietly, with ID if someone asks, and without turning a viewpoint into a smoking spot. The tourist FAQ is the one-paragraph version. Thailand cannabis rules for tourists is the slightly longer one.

Looking around the farm

You can buy and leave. You can also look.

The grow rooms are visible through an observation window. There are microscopes and a few science-fair pieces we like having in the room, because the work is horticulture, not a costume. The botanical garden opens to everyone from 15:00. None of that is required to buy flower. It is there because we wanted a place we would visit ourselves.

If you want a structured walk, there is a self-guided audio tour with a tablet for ฿350, and there are guided farm tours when you want a person with you. Those are a separate product. Most people who find this guide are here to shop. The window and the garden are enough for a look on the way to the counter.

More of the team, the hours, and the company details are on About OG Lab.

If you run a licensed shop

Retail tiers and wholesale are different conversations. If you run a licensed dispensary in Thailand and you want flower from this farm, after lab tests, that is wholesale. We already supply shops on the island. We ask for licence documents before the first order. There is no public wholesale price list. Write to us, visit the farm, and we will talk about the batch.

If you do not have a licence, the menu in the shop is the offer. Please do not ask the counter to pretend a retail sale is something else.
