The World’s Best High THC Strains 2020

Every marijuana smoker knows about THC. It’s the main psychoactive cannabinoid in the marijuana plant that many are looking for.  The main thing smokers, vapers, and dabbers enjoy about high THC strains is those mind-blowing highs. High THC strains can have you sitting on the couch lost in your own mind-bending thoughts. Or can have you giggling uncontrollably as you and your friends come up with high ideas. It all depends on the strains you use. 

For those growing strains high in THC from marijuana seeds, they can also contribute to high resin production. This can be great for those that want to make hash, or just enjoy the super frosty look of their buds as they grow.

A strain high in THC can also be beneficial for medicinal users. Sometimes conditions can be so bad that medicinal patients find they have to use a lot of marijuana. Hitting the bowl or joint several times in a very short space of time isn't always a good thing. It can contribute to some unhealthy side effects, such as damaging the lungs.  High THC strains can help with this, as fewer tokes will need to be taken, but patients will still get the relief they need.

So, now that the benefits of high THC strains are understood, what strains are best when one is looking for high amounts of THC?  For both medicinal and recreational use, these are the top ten strains high in THC in 2020.

Top 10 High THC Strains

Gorilla Glue

Gorilla Glue is a strain that combines two things many smokers love - a high THC content and all the pain relief you need. Gorilla Glue averages a THC content of around 25%, which is higher than most. It will leave users with that calming high they’re looking for.

Bruce Banner #3

Known as BB3 to its many friends, Bruce Banner #3 is a cross between OG Kush and Strawberry Diesel.  Even though it’s a balanced hybrid, it has average THC of 25% to 27%, so it packs a hulking, pain-killing punch.  The overall effect is a burst of that classic Sativa euphoria followed by a stretch of deep Indica relaxation.  Taste-wise, you get a rich, satisfying base of Kush and Diesel, topped with the sweetness of strawberry.



If you like your THC on the sweet side, then you’ll love Gelato.  It’s a cross between modern classic Thin Mint Girl Scout Cookies and Sunset Sherbert.  Even though it’s slightly Indica-leaning, it has average THC of about 26% so it’s medically effective as well as tasty.

The effect of Gelato is potent but balanced.  It starts with a rush of uplifting energy which gets rid of both pain and stress and then transitions into a soothing body buzz.  Taste-wise, it really is one for people with a sweet tooth, but it’s mostly fruity sweetness rather than candy sweetness and there are notes of earth and citrus for body and freshness.

Strawberry Banana

For those that prefer an indica smoke to a sativa, Strawberry Banana may just be the high THC strain you’ve been looking for. This strain tastes just like a dessert. Combined with indica effects, it's the perfect dessert smoke after dinner or long day. While THC levels can sometimes be as high as 31.62%, most of these marijuana seeds fall at around 26%. And that’s still enough to keep you flying for some time.

Grandfather OG

If you haven’t heard yet of Grandfather OG, you may want to look into it. This indica strain has been touted as the world’s strongest marijuana strain. That’s not surprising seeing as how its THC levels have been measured up to 28%. But just like Strawberry Banana, those who are growing their own marijuana plants will likely see THC contents of at least 25%.

Big Bruce

Big Bruce is a cross between Bruce Banner #3 and Critical Kush.  This Sativa-dominant strain consistently clocks up 22%+ THC in fact 27%+ is not that unusual.  Bruce Banner is one heavy hitter.  First of all, it knocks out pain and stress, then it holds you down (gently) and forces you to take some deeply-relaxing time-out.  Taste-wise, it’s a nice balance between Diesel and Kush, rich and complex and less sweet than Bruce Banner #3.

Gorilla Bomb

Gorilla Bomb is an indica dominant, and a potent one at that. It’s a good idea not to have too much on your calendar for the day, after smoking this strain. While some strains have been known to have up to 34% THC, they typically fall more towards the 24 to 29% range. Still, not too shabby when you need a strong smoke. It’s also been called one of the strongest strains known to man.

Chem Berry D

Chem Berry D is a cross between Chem #4 and Strawberry Diesel.  It’s Sativa-dominant and regularly clocks up 25%-32% THC.  The effect of Chem Berry D is pretty unusual.  It starts with a powerful head high, moves into an equally powerful body high and then mellows into a superbly comfortable body buzz.  Taste-wise the base is mainly Diesel, maybe with a chemical edge, but there are fruity-sweet top notes for balance and freshness.

Girl Scout Cookies

Girl Scout Cookies is a cross between OG Kush and Durban Poison.  Even though it’s only slightly Indica-dominant, it has average THC of 25% to 28%.  GSC is known for its energizing, creative, basically fun high, but it’s still mainly Indica, so this is followed by a period of deep relaxation for both body and mind.  Taste-wise, there is a base of sweet earth, but it's smoothed by creamy flavours.  This is topped by sweet spices which are balanced by mint for freshness.

Ice Wreck

Anyone that knows just how potent Ice and Trainwreck can be, will be familiar with the potency that Ice Wreck brings. Ice Wreck is a cross between those two famous marijuana plants and brings THC levels up to around 27%. Plus, this one is nearly a perfectly balanced hybrid. Smokers will get both the head high, and then can settle in for a nice couch lock perfect for Netflix and chill.

Whichever type of marijuana strain you love, indica, sativa, or a hybrid of the two, there are high THC strains out there that will suit whatever you’re looking for. And while these marijuana seeds are particularly high in THC, it’s important to remember that these are just the ones that made our top ten. And there are so many others to consider!
