At Siam Green, we’ve spent years curating the finest cannabis selection in Thailand. Our team works directly with certified growers to bring you strains that deliver on quality, consistency, and experience.
Thailand’s cannabis scene has come a long way since legalization. What started as a bold move in 2022 has evolved into a thriving wellness industry that’s reshaping how locals and tourists alike think about cannabis. From the bustling streets of Bangkok to the beaches of Koh Samui, Thailand has embraced cannabis not just as a trend, but as part of its rich tradition of herbal medicine. Today, you’ll find everything from CBD cafes to premium dispensaries offering world-class strains. But with so many options flooding the market, how do you know which flowers are actually worth your time? That’s where we come in.
After listening to thousands of customers and tracking what keeps people coming back, we’ve narrowed it down to our absolute favorites for 2025! Whether you’re looking to unwind after exploring temples, spark creativity, or just get a good night’s sleep in your hotel, these seven strains have something for everyone.
Our Top 7 Strains of 2025
1. Grape Stank (Sativa-dominant)
Let’s kick things off with a crowd favorite. Grape Stank is the kind of strain that makes you stop and go, “Wait, what was I worried about again?” This sativa-dominant beauty is known to bring together creative energy and social vibes with a surprisingly calming edge. Expect flavors that blend grape, citrus, and a gassy kick that’s become its signature. Perfect for exploring Bangkok’s night markets or vibing with friends at a rooftop bar. Just don’t blame us when you suddenly become the most talkative person in your group.
2. Permanent Marker (Indica-dominant)
If you’re the type who likes to ease into the evening without getting knocked out completely, Permanent Marker is your go-to. This indica-dominant strain hits with a strong high that is known to be both relaxing and blissful. The rich floral and earthy aroma sets the stage for a peaceful journey that helps melt away travel stress. Great for winding down after a long day of sightseeing or when you just want to sink into your hotel bed and watch something mindless. Fair warning though…the munchies are real with this one.
3. Blue Runtz (Indica-dominant)
Blue Runtz is what happens when happiness becomes a physical sensation. A few minutes after your first session, this indica-dominant gem is known to lift your mind into pure contentment while washing your body with tingly, relaxed vibes. The creamy, musky flavor profile with hints of apricot and lemon makes it smooth and enjoyable. This is the strain for lazy beach days in Koh Samui or when you want to feel fully at ease without overthinking anything.
4. Charlotte’s Angel (CBD)
Not everyone visiting Thailand is chasing a heavy high, and that’s exactly why Charlotte’s Angel made our list. This CBD-rich strain is known for therapeutic benefits without the psychoactive punch. Users report relief from pain and better sleep quality, with deeply relaxing properties that feel like a warm hug. The fruity, pine, and mango notes make it pleasant to consume, and it’s a favorite among wellness-focused travelers. Think of it as your natural reset button after all that pad thai and temple climbing.
5. Tropical Tsunami (Sativa-dominant)
Want to stay sharp and focused while still feeling good? Tropical Tsunami is known to deliver an uplifting, energizing experience that keeps your head clear. This sativa-dominant strain is perfect for daytime adventures when you want a little boost without sedation. The orange and citrus flavors are refreshing and fruity, making it an ideal companion for beach activities or creative projects. It’s also great for managing stress and mild discomfort without slowing you down.
6. Ultra Mango Haze (Sativa-dominant)
Sometimes you want the best of both worlds, and Ultra Mango Haze delivers exactly that. This hybrid strain is known to offer an uplifting, euphoric high that boosts mood and creativity while keeping you relaxed enough to enjoy the moment. The sweet mango flavor is tropical and hazy in all the right ways. Whether you’re exploring Bangkok’s art scene or just hanging out with new friends at your hostel, this strain keeps the vibes positive and the conversation flowing.
7. Zapple (Sativa-dominant)
Rounding out our list is Zapple, a balanced hybrid that’s become a favorite for its versatility. With sweet, fruity flavors and citrus notes, this strain is known to bring uplifting and euphoric effects that help with stress and anxiety. It’s suitable for various occasions, whether you’re heading out for the day or settling in for the evening. Think of it as your all-purpose travel companion—reliable, enjoyable, and never too much.
