Top 10 Strongest THC Strains

strongest thc strains

Back then, people who smoked weed were happy if it made them sleepy or “stoned.” But now, people want marijuana with a higher amount of THC. The effects of marijuana were not the same as they used to be. More people who use drugs for fun want stronger effects. Breeders and growers have had a hard time with this.

If you want to see how far you can go with marijuana, you might want to check out these strains that will blow your mind.

Royal Gorilla

This strain had a THC level of up to 30%, which was the next step up. Chem Sis, Sour Dubb, and Chocolate Diesel were accidentally crossed, which led to the birth of Royal Gorilla. Even seasoned customers were impressed with how strong the final product was.

About 500 to 600 grams per plant can be harvested after 8 to 9 weeks (once dried).


The THC level in The Destroyer is about 20%, which is very high for a pure Sativa. This strain can make you feel alert and happy. Compared to other Thai-cross plants, Destroyer grows quickly.

It smells and tastes sweet and has a strong lavender scent. In 8 to 12 weeks, it will start to bloom, and it can also fight off mold.

Fat Banana

US West Coast Banana OG is a parent strain of Fat Banana. It tastes fruity and sweet, and it has up to 25% THC and more. With this strain and your couch, you’ll be in a very relaxing state. It is so strong and has such a unique taste.

Fat Banana will bloom in about 7 to 8 weeks, and each plant will produce about 400 to 500 grams (once dried).


You are right, the name sounds familiar. It is the same as the highest mountain peak in Africa. That’s because it has about 20% THC, which is one of the highest levels of all Sativa strains. It was seen growing in the mountains of Tanzania. It has a nice smell and tastes like citrus. Kilimanjaro is now a well-known name in Canada.

Purple Queen

This strain has a bright violet color with a hint of lavender. You can probably guess where the name came from now. The earthy and lemony smell of Purple Queen will fill the air. It’s a cross between the Hindu Kush and the rare mountain Kush.

Purple Queen has a THC level of up to 25%, which is high enough to send you straight to your dreams. In 7 to 8 weeks, the plants will bloom. About 650 to 700 grams are produced per plant (dried).

Once the Purple Queen has dried, you’ll be able to see its true beauty, both on the outside and in its effects. Explore this strain and grow it, then cure and dry it to get a beautiful crop.

Ghost Train Haze

High Times now calls Ghost Train Haze one of the “Strongest Strains on Earth.” This strain is made up of 70% Sativa. It is a mix of Ghost OG and Neville’s Wreck. It can have as much as 28% THC. It tastes a little bit like kush and a little bit like fruit.


This strain is hard to find and has been a dream of some growers and breeders because it can get big and still have a THC level of 22%.

It smells like citrus and fruit and tastes a little bit like wood and bitterness.

Thai strain will keep you alert and happy, but you should be careful not to smoke too much.

Bruce Banner

You did read it correctly. The name of the Hulk when it looks like a person. This strain won’t make you big and green, but the effects are still worth trying. Bruce Banner has more than 24% THC, which is why it is one of the top three strains with the most THC. Bruce Banner is a mixture of OG Kush and Strawberry Diesel.


This strain is 60% indica, and it tastes sweet and fruity and smells strongly of citrus. About 18% to 19% of THC is in wappa. It is easy to find, even in the US. It yields a lot, which is impressive, and it blooms quickly, too.

Amnesia Haze

The effects of Amnesia Haze are mental, and they happen right away. This is why it is one of the most popular drugs. It tastes like citrus from the tropics and smells like spicy musk.

This type of marijuana makes you feel good. It can make you feel trippy and euphoric, and it relaxes your body very deeply and for a long time.

Flowering takes about 12 weeks, and each plant can produce between 650 and 700 grams. The genes that make up Amnesia Haze come from Original Haze, Southeast Asia, and Jamaica. The amount of THC in this strain is at least 20%.

In the past, you could get marijuana with up to 10% THC. As time went on, people started to want marijuana with more THC.

This will also put your name on a list of famous breeders if you have made one. The effects of marijuana are the best way to tell if it works or not, and it has been shown over and over again that the effects can be improved by crossing strains in line with new trends and techniques in growing marijuana.

We might end up with a super weed that gets you high for days, and we hope it can also be used in medicine. That idea isn’t too far-fetched.

In the future, we’ll be waiting for more hybrids that might have higher THC levels than the top 10 right now. We’ll also be looking forward to more research into how cannabis can be used for both recreational and medical purposes, especially for people who are dying. At least this way, it can help speed up the process of making marijuana legal.
