Siam Green Cannabis Co Nana — Bangkok Dispensary near Nana BTS: Review, Hours and Strains 2026

Siam Green Cannabis Co operates five locations across Thailand. The owner has a personal history with epilepsy and found relief in cannabis, specifically CBD, during that experience. That background shaped the mission: to deliver the right products to people who genuinely need cannabis as medicine. The range of unique Thai-made products stocked alongside the flower reflects the same philosophy.

Beyond flower, the shop carries medical herbs, functional mushrooms, and CBD products with genuine therapeutic intent. This article covers the most popular products with input from staff, introducing each one individually.

Strains Available at Siam Green Cannabis Co Nana

Alien Tits is a strain built on a tropical fruit and creamy sweetness profile. The aroma layers mango and pineapple-like fruitiness with a smooth vanilla-cream sweetness and a faint citrus lift. The overall effect is distinctive and layered rather than one-dimensional: the fruit comes first, then the cream builds in the back half, combining into something closer to a tropical dessert than a simple sweet. The dominant terpene, Limonene, also found in lemon and orange, keeps the fruit notes fresh and bright rather than heavy. For people who want both aroma depth and something that shifts noticeably over the course of a session.

What Makes Siam Green Cannabis Co Nana Worth Visiting

The Nana location stands out for its staff training structure. Every staff member is required to attend weekly classes run by Thai Budtender Academy, Bangkok’s largest cannabis education institution. The curriculum covers current strain information, terpene knowledge, and Thai regulatory updates, refreshed weekly by specialists. The result is that staff don’t guess: describe how you want to spend your time and they come back with a recommendation grounded in experiential direction, aroma, and terpene composition.

Watching the floor over time confirmed this. Staff remembered regular customers’ strain preferences and consumption habits. First-time visitors received careful explanations of safe use and dosing. The posture throughout was less about selling and more about finding what actually fits each person.

On the wall, a plaque: Thaiger Top Shelf Award — January 2024, Best Interior Design.

The Thaiger Top Shelf Award is a monthly recognition by The Thaiger, one of Thailand’s largest English-language media outlets, given to standout cannabis dispensaries across Thailand. Being named “best-designed dispensary in Bangkok” by a major media organization, at a time when over 8,000 dispensaries were competing for attention across the city, is a meaningful distinction.

Operating licenses, regulatory approvals, and certification documents from relevant authorities are displayed clearly on the wall. Legal proof that the shop operates in compliance. Thailand’s cannabis regulations have shifted considerably over the past few years, and it isn’t always straightforward to know which dispensaries are fully compliant. Displaying this documentation prominently communicates transparency in a way that matters, especially for first-time visitors.

The first CBD product staff recommended without hesitation was the Suk Jai (สุขใจ) CBD Extract Massage Balm, priced at ฿300. Made with Pure CBD Isolate — meaning CBD extracted to its pure form, with no THC, no other cannabinoids, and no terpenes — the product delivers the effects associated with CBD directly, without any psychoactive component.

CBD Isolate is CBD extracted from cannabis and purified to remove everything else: THC, other cannabinoids, and terpenes are all absent. The result is the most targeted form of CBD available, suited to people who want CBD’s effects without anything else in the mix.

No THC means no psychoactive effect, making this an accessible entry point for anyone new to cannabis-adjacent products or wary of strong physical sensations. The Fast Acting claim on packaging and the compact size make it a practical pick-up for travel: shoulders, legs, neck tension from a day of walking. The lowest-barrier product in the Siam Green range.

Staff mentioned a product they recommend pairing with flower: the WILDER Performance Hydration electrolyte drink mix, ฿60 per sachet. Available in pineapple, strawberry, yuzu salt, and other flavors, the formulation combines sodium, potassium, magnesium, and L-theanine — designed not just for hydration but for supporting muscle recovery and sustained focus. Zero sugar, fast hydration.

Most people picking this up were using it as a practical response to the dry throat and mild fatigue that can follow cannabis use — not chasing a strong effect, but building a comfortable baseline to work from. It functions as a low-profile companion product rather than a statement purchase.

When asked for non-cannabis product recommendations, staff pointed to two: Cordyceps Mushroom Extract Capsules (฿1,790) and Lion’s Mane Mushroom Extract Capsules (฿1,690), both USDA Organic certified.

USDA Organic certification is issued by the United States Department of Agriculture and indicates that a product has been produced without synthetic pesticides or chemical fertilizers, meeting internationally recognized standards for organic quality.

Cordyceps tends to attract people concerned with energy and stamina. Lion’s Mane tends to attract people focused on mental clarity and concentration. Neither is fast-acting in the way a supplement for immediate effect would be; both are designed for consistent use over time to support overall condition. A significant share of buyers were planning to continue using them after returning home.

Staff also highlighted the Pet dee CBD Oil (฿1,000) — a CBD oil formulated specifically for pets — as something gaining traction among cannabis-familiar visitors who own dogs or cats. As pets live longer, age-related conditions including joint inflammation and mobility issues have become more common, and CBD-based products for animals have followed.

Pet dee is organized across three use categories: Pain, Mood, and Skin and Fur, with a weight-based dosing guide included. Dosing runs from 1–3mg for dogs 2–5kg, 3–5mg for 5–12kg, and scales up from there. For owners managing joint or mobility issues in older pets, this is a product worth considering.

For visitors who prefer to avoid bringing ingestible products across borders, Siam Green’s original apparel fills the gap. The most consistently popular item is the classic logo T-shirt, with the brand logo on front and back. Several colorways are available; the grey reads as the most versatile.

The laser-engraved bamboo bong with geometric patterns and the Siam Green logo is another popular souvenir. Bamboo bongs have roots in Southeast Asian cannabis culture, which adds meaning beyond the object itself. Dispensaries in Bangkok that stock bamboo bongs are fewer than you might expect, so this is worth noting if it’s on your list.

The organic hemp rolling papers are a personal favorite — the paper that goes into a joint ends up as smoke, which makes the quality of what you’re rolling with matter more than it’s usually given credit for. The Siam Green organic hemp papers hit the right size. Staff mentioned that buying papers, a grinder, and a rolling tray together is common, and listening to in-store conversations made it clear why: the conversation naturally goes there.

On more than one visit, exchanges between customers and staff sounded less like retail and more like familiar conversation — “That strain you recommended yesterday was perfect for what I needed.” The warmth of the store comes not just from the interior design award but from the combination of well-trained staff and genuine investment in the customer’s experience.

What Siam Green Cannabis Co. communicates consistently is a focus on “how you want to spend your time” rather than “what to consume.” Flower, edibles, CBD drinks, herbal blends, kratom, papers and tools, and apparel share shelf space without any element dominating. The space doesn’t compete on intensity or novelty. There’s a lot to choose from, and somehow it stays easy to move through.

The entry-level option here is low: the Suk Jai massage balm at ฿300 requires no prior cannabis experience, no tolerance for THC, and no explanation. The ceiling is equally accessible for experienced users who want to go deeper into strain selection or explore how CBD products fit into daily life.

Siam Green is a place that keeps cannabis from feeling like a specialty category, and quietly positions it as something that fits naturally into how you look after yourself.
