Siam Green Cannabis Co Chinatown Review 2026 — Strains, THC Drinks, CBD Products & What to Buy in Bangkok’s Yaowarat

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 need cannabis as medicine. The range of unique Thai-made products stocked alongside the flower reflects that same philosophy.

Beyond flower, the shop stocks cannabis-adjacent medicinal herbs and mushrooms 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 Chinatown

Black Cherry Flambé is a hybrid strain with a rich, layered aroma profile built on ripe black cherry sweetness, berry fruitiness, and a faint spice undercurrent. The first inhale delivers the density of black cherry jam, followed by a slow-building combination of tart berry and spice notes that extends into a long finish. The overall profile is fruity and composed rather than loud, with the complexity coming from layering rather than intensity. The primary terpene, Caryophyllene, contributes the spice dimension and structural depth that holds the black cherry sweetness together without letting it tip into one-dimensionality. A profile for people who want to linger over aroma and flavor, and for anyone who wants both fruit and complexity in the same strain.

What Makes Siam Green Cannabis Co Chinatown Worth Visiting

The Chinatown location is more compact than other Siam Green outlets, but the limited floor space holds a concentrated version of the brand’s curated selection.

Beyond flower, the shop carries CBD oil, cannabis beverages, massage balm, and apparel. Unique products available specifically because this is Thailand. Visiting the store on my own trip, there were items I hadn’t seen at other cannabis dispensaries, and walking through the full range gave a clear sense of how broadly cannabis culture has embedded itself in Thai daily life.

I bought several things on this visit, and what follows covers the products that made the strongest impression.

Siam Green tends to get attention for flower quality, but the full product range extends well beyond that. CBD oil, cannabis beverages, aroma oil, and apparel are all on the floor. Several of the items I picked up were things I hadn’t come across in Japan, which made them interesting as souvenirs on top of being interesting products in their own right.

The notes below include personal impressions from things I actually tried.

The first product worth highlighting is the SEYA Broad Spectrum CBD Oil, which staff mentioned is popular with visitors from countries where CBD is legal. Two formulations were stocked: Better Sleep (1500mg), positioned for pre-sleep relaxation, and Pain Relief (3000mg), aimed at daily condition management.

CBD is one of the compounds found in cannabis, but unlike THC, it does not produce psychoactive effects. This has made it a focus for people who want relaxation and physical balance without the intoxicating high.

The BILEAF CBD Happy Stick is a roll-on aroma oil combining CBD with plant-derived essential oils. The formulation includes CBD alongside lavender oil, eucalyptus oil, and citrus-based oils, designed for a clean, fresh scent experience.

The roll-on format allows direct application to the skin, making it practical for wrists, neck, or anywhere else you’d apply a fragrance. The compact size travels easily, which makes it genuinely useful during trips rather than something you buy and leave in a drawer.

The Sukjai Thai CBD Extract Massage Balm is a massage balm using Thai-sourced CBD. The packaging describes it as a bodycare product combining CBD isolate with plant-derived ingredients, and display materials note “Pure CBD Isolate,” “Fast Acting,” and “Refreshing Formula” as the main product claims.

The tin format is compact and portable. The intended use is application with massage to shoulders, neck, arms, legs, or wherever there’s tension. Positioned for everyday self-care and refreshment rather than clinical treatment.

On the more unusual side: the WIZMAN 420 POP-UP GRINDER is a foldable paper grinder that merges Thai cannabis culture with pop art design. It looks like a comic book from the outside, but opening it reveals a grater-format grinder built into the interior for breaking down flower.

The standout feature is the illustration work based on Thai mythology and cultural references, with the packaging designed as a narrative visual story. It sits somewhere between smoking accessory and collector’s item rather than being purely functional. Lightweight and packable, which makes it easy to take along.

For Thai-specific items, the new release from Siam Green’s original apparel line, the Siam Green Apparel Collection Thai pants, stand out. The design uses elephants, tuk-tuks, and lotus flowers as motifs while keeping the overall aesthetic measured rather than loud.

These are a step removed from the generic tourist-market Thai pants. Combining the Siam Green brand logo with Thai motifs produces something wearable in daily life rather than purely as a souvenir. Matching shirt and pants sets are available, making them practical as resort wear or relaxed travel clothing.

The Siam Green Activewear Collection uses a lightweight sleeveless design suited to Thailand’s heat. Simple logo placement and a range of vivid colorways make these versatile across gym, running, beach, and everyday wear.

The cannabis connection is understated rather than billboard-style, with the brand logo handled as a single accent point. From observation, these read as sportswear first rather than cannabis brand merchandise, which is what makes them wearable outside of specific contexts. Popular as a trip souvenir and as functional activewear in equal measure.

The accessories section covers rolling trays, grinders, ashtrays, papers, and stickers. Items that make the smoking experience more comfortable and enjoyable.

The consistent Siam Green green across the range gives everything a unified feel. Wave patterns and leaf designs appear alongside the brand logo, pushing the items into lifestyle goods territory rather than purely functional smoking accessories.

Price points are accessible, and many items sit naturally alongside a flower purchase. From watching other visitors in the store, rolling trays and stickers were frequently picked up as souvenirs. The trays travel easily, and the stickers are even more so. Both work as lightweight takes on Thai cannabis culture to bring home.

Before getting to what I actually bought: some context on how the visit played out.

Siam Green staff go through regular product and cannabis education sessions, which was evident from the quality of conversation in-store. When I visited, explanations of product differences were thorough and specific, and the approach was “based on what you’re looking for, this might interest you” rather than defaulting to whatever’s popular.

The products I’m about to describe came out of that conversation. Staff introduced each one with explanation of the characteristics and how to approach them, which meant I ended up with things I wouldn’t have reached for on my own.

When I mentioned I was looking for a hybrid strain suited to a quiet, relaxed session, staff recommended Grape Skank. Grape Skank is a strain defined by the combination of dense, ripe grape sweetness with the funky, slightly gassy character of Skunk genetics. Trying it confirmed the layered profile: the flavor was as complex as the aroma, and it was one of the more memorable strains from this visit.

Local Boys “Grapefruit OG” is a Thai-made THC sparkling drink combining grapefruit flavor with cannabis. The bottle uses a tropical sunset design that fits the local atmosphere.

The defining characteristic is grapefruit’s distinctive bitterness alongside bright citrus freshness. The sweetness is restrained compared to most sparkling drinks, which makes it feel cleaner and easier to drink than standard carbonated beverages. My personal experience aligned with this: it read closer to a light craft soda than a fruit juice, and worked well as a refresher on a hot day.

The balance of natural grapefruit acidity and carbonation is clean, and it sits comfortably alongside food.

The final product is the CIBID CBD Craft Soda, a craft-soda-format CBD cannabis drink. I’ve had the Pineapple and Coconut flavor before, which combined pineapple’s fresh sweetness with a mellow coconut character in a flavor profile that fits Thailand’s climate well.

On this visit, after staff recommended Grape Skank, I paired it with Local Boys “Grapefruit OG.” Starting with Grape Skank’s dense grape sweetness and funky aromatics, then following with the grapefruit sparkling’s clean bitterness and acidity, let both the flower and the drink express their individual characters without one overwhelming the other.

I usually consume flower on its own, but pairing cannabis drinks with it opened up a different approach to the experience. For me, it was a genuine discovery of how cannabis culture in Thailand extends beyond what I’d been engaging with.

After visiting Siam Green Cannabis Co Chinatown, Thipsamai Pad Thai nearby is worth adding to the plan. Thipsamai is a long-running institution in Bangkok’s old city, also known as “Pad Thai Pratoopee” for the flame-finished version of the dish. The noodles have a more pronounced toasted character than typical street versions, and the approach to shrimp and egg has built a reputation over decades.

The omelette-wrapped pad thai in particular draws visitors consistently, and it works as a natural follow-on to a shop visit at Siam Green. Chinatown offers many street food options, but if you want a proper sit-down meal at a well-established restaurant, Thipsamai is worth factoring into the evening.

Visiting Siam Green Cannabis Co Chinatown confirmed something that’s easy to understate: this is not just a place to buy cannabis. It’s a place to experience Thai cannabis culture directly. CBD oil, massage balm, aroma oil, THC beverages, apparel. The full range shows how cannabis has been integrated into everyday life here, across wellness, lifestyle, and social spaces.

Staff knowledge was equally notable. Describing what you’re looking for produces specific, tailored recommendations rather than a generic list. Grape Skank and Local Boys “Grapefruit OG” both came out of that kind of conversation, and both turned into discoveries I wouldn’t have reached on my own.

The Chinatown location adds another dimension. Shopping here flows naturally into food tourism, and Thipsamai Pad Thai afterward rounds out an evening that’s genuinely Bangkok in character. In my own terms, Siam Green Cannabis Co Chinatown is less “a place to buy cannabis” and more “a door into Thai cannabis culture.”

If you’re looking for flower, the selection is there. If you’re looking for CBD products, cannabis beverages, or Thai-specific souvenirs, the range is equally strong. For anyone visiting Chinatown, it’s a worthwhile stop alongside the food and sightseeing.
