A strain that needs a fair amount of precise control to get the result you want correctly is a great way to get into more advanced growing for the cannabis newbie.

Landrace strains are a distinctly rare experience that few people get a chance to enjoy. Despite being the true originators of cannabis worldwide, they are still not common in the west.

It is a real shame to miss out, though, as landrace strains like Highland Thai offer up incredible flavors and even more impressive effects. With a great blend of typical cannabis effects, landrace strains are something everyone should try at least once.

Let’s investigate the Highland Thai strain and find out if it is worth trying it over more conventional cannabis options.

What Is the Highland Thai Strain?

Highland Thai is a difficult strain to pin down. This strain’s exact parentage is varied, descending from the high mountainous region near Burma. This strain is a piece of history, originating from a few other landrace strains, including the confusingly named Yunnanese Chinensis.

All this means it offers a great blend of different effects and aroma that you might not typically expect in a strain from the east.

If you have never tried landrace strains, you might be surprised to find the high is incredibly intense. The high of the Highland Thai strain feels almost classic, providing a brilliant, trippy effect that takes hold almost immediately.

One of the first things you will notice is the sensation of great racing in your heart, which can feel pretty frightening. This makes Highland Thai remarkably similar to those first strains that arrived on US soil back in the 1960s, giving you the chance to participate in marijuana’s history.

In fact, if you have a chance to give it to an older friend or parent, especially one that smoked cannabis back in the day, you might help them experience a pleasant nostalgia trip.

It isn’t all intensity and discomfort, though. There is also an expansion of consciousness. You will notice that your perception of the world around you expands, giving you the feeling of total awareness and mental acuity. You won’t necessarily want to jump up and engage with a creative project, but you also won’t want to sleep either.

It is a troublesome high to accurately describe because it is, above all, a sensation of timelessness and mental expansion. If you have ever seen images or videos of stoners decades ago leaning back satisfied after toking, you might have an idea of what kind of high Highland Thai will give you.


The specific aroma of the Highland Thai strain is a bit difficult actually to identify because different variations of this strain have different aromas.

This is because different growing techniques and phenotypes have different initial aromas. Green phenotypes tend to be somewhat citrus-like, along with an inherent muskiness. However, if the coloration is purpler, then you might find it more tropically fruity, alongside just a touch of that oddly distinct vegetal smell.

This diversity is what makes Highland Thai’s aroma a bit difficult to identify, as different phenotypes are so fundamentally different from one another.


As expected, the actual taste of the Highland Thai strain differs dramatically depending on which phenotype you are enjoying. The purple varieties have that same fruitfulness that you’d expect from its aroma, but its vegetal flavor is much higher.

This distinct vegetal flavor is almost a bit too much, leaving some to prefer the flavor of the greener phenotypes. Once again, these are a lot more citrusy, along with that slightly tangy acidity you would expect from a classic landrace strain like Highland Thai.


The critical quality of the bud’s appearance is that it shifts depending on how it is grown. With colder temperatures, the plant develops purple leaves and bright coloration, giving it that signature appearance.

Besides that, the buds are tight and compact, with pistils working their way through. It is also oddly put together, with the plant’s branching being not quite symmetrical. This can make it a bit of a challenge to grow yourself because it requires some special knowledge.

So, what kind of specialized knowledge do you need to know to be able to grow your own? How can you encourage the very best coloration?

Highland Thai Strain Grow Info

Getting hold of some Highland Thai strain seeds is the first real challenge you need to consider when growing some for yourself. As it is a landrace strain, seeds tend to be a bit different from breeder to breeder, so you need to find a phenotype you like yourself.

When growing it, the main things you need to consider are its uncharacteristic branching, and how to cultivate its unique coloring.

Managing its branching is all about utilizing correct tethering and trimming to ensure it doesn’t choke itself. Keep it trained against a trellis to ensure it remains stable and sturdy as it grows.

To create a different coloration, you need to manipulate its temperature as it grows. To create a purple color, it needs to be subjected to colder temperatures, ideally during the night, and extremely regularly. Make sure it doesn’t go too low, though, or you risk damaging your plant as it attempts to grow.

Other than that, Highland Thai benefits from regular trimming in the same way all cannabis plants do. Simply trim off the very tip of the plant as it grows, allowing the plant to focus on growing more laterally, instead of tall. The lateral growth is better for utilizing the sunlight to grow more bud.

As long as you keep your Highland Thai in appropriate conditions and trimmed, it will likely grow just fine. Landrace strains are well known for both hardiness and their ability to resist both pests and disease, making Highland Thai a great strain to grow in adverse climate conditions.

THC Content – Highest Test

A big problem with most landrace strains is that their precise cannabinoid content is not especially potent.

While Highland Thai obviously does have a great deal of intensity, the exact amount of THC is not entirely clear. It likely possesses at least 15% THC, though it is unlikely to tip over the 20% mark.

CBD Content – Highest Test

Once again, the precise content of CBD within this strain is not explicit. However, it almost certainly has at least some CBD content, despite its more robust THC content, due to its landrace origins.

Since it has not been so aggressively bred to encourage more durable and more reliable THC content, there will be a small amount of CBD to balance out its strong THC effects.

This enables a multitude of beneficial medical effects of this strain, thanks to the decent blend of the two cannabinoids.

Medical Benefits of the Highland Thai Strain

The great thing about landrace strains with a blend of different cannabinoids is that they offer up all kinds of medical benefits. In fact, every single medical benefit you can associate with cannabis can be found in the Highland Thai strain.

It is a great way to reduce any kind of long-lasting pain or chronic aches you might struggle with. Additionally, if you find yourself plagued by inflammation or aching joints, this strain can be a great way to deal with it.

On the mental side of things, Highland Thai is great at helping keep back feelings of depression. As it is able to help suppress any kind of negative thoughts, you can also use it to help treat things like anxiety, or even large amounts of chronic stress.

The careful balance of CBD within this strain means that you will find yourself feeling all manner of different medical benefits, all combining together. You will be soothed, relaxed, and chilled out all at once, leaving you entirely and totally assured of your place in the world. Use Highland Thai to feel comfortable, both physically and mentally, while still able to carry on with your day.

Of course, there will always be a few side effects associated with any cannabis strain, no matter how natural it might be.

Possible Side Effects of the Highland Thai Strain

Despite its pleasant cannabinoid mixture and gentle landrace origins, even Highland Thai can’t avoid having some side effects.

The first things you will notice will be both dry eyes and dry mouth, which are as familiar as the high of cannabis itself. It isn’t at all unpleasant, though, and is easily fought off with plenty of cold water.

Besides that familiar side effect, there are some reports of people struggling with both headaches and spells of dizziness after smoking Highland Thai. However, this might be because it has a tendency to hit you quite strongly, as well as induce a plentiful amount of that mildly uncomfortable trippiness.

This trippiness can certainly overwhelm the inexperienced cannabis user, which can lead to these kinds of unpleasant side effects. However, the best way to avoid them is to watch your Highland Thai intake.

As long as you are smoking the right amount of Highland Thai for your body weight, you likely won’t struggle too much.

Final Thoughts on the Highland Thai Strain

The Highland Thai strain is an interesting example of a cannabis strain that is both a great piece of history and a brilliant strain in its own right.

Able to offer up plentiful medical benefits and a great deal of charming, trippy effects, this is a strain to take in aid of relaxation and calm.

You should share your Highland Thai bud with older relatives and friends who experienced cannabis in the ’60s and ’70s, or with anyone who wants to sample a bit of cannabis history.

Difficult to find on its own, this strain is a bit of a rare find. This is not helped by the fact that two distinct phenotypes exist, making it almost impossible to source which type of Highland Thai you actually like.

If you can find it, you should definitely give Highland Thai a try, even if just to experience the pure joy of its trippy, gently pleasant highs. Don’t worry about the heartbeat rush either; it’ll soon pass.
