The Top High THC Cannabis Strains in 2022

Thanks to advancements in technology and crossbreeding techniques, cannabis is available today with a higher THC content than ever before. According to one study by the National Library of Medicine, the potency of weed has tripled over the last thirty years. That’s a lofty claim and one that’s hard to test.

One thing we can attest to, however, is that there are new strains available today with truly eye-popping levels of THC. But before we introduce the top high THC cannabis strains, let’s look at what it all means.

What is THC?

THC, or tetrahydrocannabinol, is the primary psychoactive compound found in the marijuana plant. It’s the cannabinoid responsible for most of the psychological effects you feel when you ingest cannabis by any means, be it smoking, vaping, eating or dabbing. In other words, it’s the one responsible for getting you high.

THC is chiefly found in the resin glands on the flowers of female cannabis plants, known as trichomes. It’s a powerful substance that stimulates cells in the brain, releasing dopamine. The upside of this is that it can lead to euphoria, changing the way you think and even making you feel more creative. Add pain relief, relaxation, and full-on sedation to the list of effects, and it’s not hard to see why THC is such an incredible compound.

How people respond to THC can differ significantly. Some people may become more relaxed, while others experience full-on sleepiness, bouts of anxiety, or even paranoia. What you feel from THC can depend on many factors, but one of the biggest of these is tolerance. An experienced cannabis user will have a high tolerance level; over time, they have become ‘used to’ having THC in their body. As such, they may find weed strains with medium to high THC levels no longer give them the same buzz they used to experience. A less experienced cannabis user, or a newcomer, may find that just a couple of hits are mind-blowing and quickly succumb to the plant’s psychoactive effects.

The Best High THC Strains

If you’ve ever wondered about or wanted to try some of the higher-THC strains available, the good news is there are plenty. A word of warning, though – proceed with caution. These are among the best weed strains, are not for the faint-hearted. Beginners should be careful with dosing whenever consuming high THC strains.

With that out of the way, take a deep breath and make sure there’s a couch nearby. Here are the top high THC cannabis strains in 2022.

Purple Ghost Candy

When it comes to high THC cannabis, Purple Ghost Candy stands out among the best cannabis strains for several reasons. First of all, it’s stunning. The leaves have an ornate majesty, but the flowers are the real show-stoppers.

Purple Ghost Candy

You can quickly identify this strain from a distance by its striking purple and violet-coloured colas, and you can tell it’s quality cannabis by the appearance alone. Closer inspection reveals an abundance of dazzling trichomes, equating to a potency that’s hard to rival. Bear in mind that a good high THC cannabis delivers around 20%, then realise Purple Ghost Candy packs an eye-popping, jaw-dropping 27% THC. This is connoisseur cannabis in every way.

It’s a genetic cross of Ghost OG and Candyland Purple, making it a sativa-dominant hybrid. With relatively low levels of CBD, Purple Ghost Candy is all flavour and effects. The taste balance reads like the description of a fine wine, too. Spicy, earthy, with lemon-lime and peach tones, and a crisp mint-like bite on the aftertaste.

There’s a dazzling array of accompanying effects to Purple Ghost Candy, too. Intense relaxation for the body and mind is coupled with cerebrally stimulating effects. You can chill out to the max and still maintain a sharp social presence. This potent and delicious superstar sativa strain is easy to grow, too. It yields high, and while it carries a maximum flowering time of 12 weeks, it is worth every second of the wait.

Peyote Zkittlez

In contrast to the sativa-dominant splendour of PGC, Seedsman presents Peyote Zkittlez – one of the finest indica-dominant strains with staggering potency. By combining Peyote WiFi with Zkittlez, you find yourself with a powerful plant and simply sensational taste.

The THC content of Peyote Zkittlez is off the chain – between 26-28%, combined with mouth-watering tropical fruits and candy flavours. You won’t just taste this rainbow. You’ll hear it, feel it, and possibly even slide down it.

Peyote Zkittlez has the added advantage of being relatively easy to grow, and the yields are the impressive as the effects. Outdoor cultivators can anticipate as much as 1500gm/plant of quality nugs of cannabis. Its effects are as powerful as you’d expect, and while being a tremendous strain with a body high for relaxation, it’s surprisingly uplifting for an indica-heavy weed. This strain is a hit with medical cannabis users, too – benefits include combating anxiety and stress, making this strain a winner on all fronts.

Peyote Forum

What is it about these Peyotes? They all seem capable of breaking the needle on THC testing, and Peyote Forum is no different. In the right conditions, with the proper treatment, it’s reckoned this highly potent strain can tip the scales at 28%!

This is a finely balanced indica/sativa hybrid, born from a Girl Scout Cookies Forum cut spliced with Peyote Purple. The result is a plant as green as green can be, with the most subtle purple hues among its flowers. Upon closer inspection, you’ll see a dazzling array of prized trichomes, and quality is assured in every aspect of Peyote Purple’s make-up.

The yields may be modest, but don’t let that fool you – Peyote Purple is marijuana par excellence. A highly pungent variety, the strong Skunk characteristics from GSC are evident in its aroma, with flavours of nuts and sweet pine to boot. Lovers of genuinely dank weed will be impressed.

The effects of Peyote Forum are as pronounced as you’d hope  – maximum relaxing results, especially in the head, but with a cerebral kick. This strain can lead to sleepiness with heavier consumption, so don’t make any plans! Medical marijuana users will love the therapeutic benefits, which are said to include relief from glaucoma, headaches, migraines and stress.

Gelat OG

When you combine two strains with the quality, popularity and high potency of Gelato and OG Kush, you can only breed a winner. That’s how Gelat OG came into existence, and the outcome of this project is a winner.

This sensational California-styled strain ticks every box on the list. Easy to grow, high-yielding, succulent flavours, and the reason it makes this list – THC content of 25%. When you couple that with a low CBD content, you get a cannabis strain that’s all-powerful. An excellent strain for relaxation, the high THC content and mostly-indica nature of Gelat OG will soothe and relax as few others can.

gelat og plant

The name conjures images of fine Italian ice cream, and the taste delivers in spades. Fruity, citrusy and sweet, this is practically a dessert thanks to its supremely appetising palatable taste. The Kush factor in its lineage means this purple enchantress packs just a hint of earthiness and is well-suited to a vape. The intense aromas from this beauty call for indoor growers to practice diligent odour control.

Gelat OG requires responsible use, and as with any high THC indica strains, novices may find themselves floored with couch-lock after just a couple of puffs.

Banana Punch

If you want a colourful, potent weed with a tropical flavour, you want Banana Punch from Barney’s Farm. This is an elite strain with plenty of kick, so not one for the faint-hearted.

Barney’s Farm married two top-notch strains – Banana OG and Purple Punch. The result is Banana Punch, and with a THC content of 26%, you can bet your boots it packs a punch. It’s 55% indica and 45% sativa, meaning a blanced and potent distribution of effects. Dominant terpenes are limonene, myrcene, and caryophyllene.

Banana Punch is another fairly easy-to-grow strain, performing well indoors or out. Experienced cultivators can use a range of techniques to maximise her already-impressive yields, which can see up to 155 gm/plant achievable in an outdoor setting!

After a flowering time of just 9 weeks, Banana Punch turns any grow area into a sea of vibrant colours and sweet aromas. Sweet citrus, banana and tropical flavours give this strain the kind of palatability you can’t get enough of – but the compelling euphoric high and relaxing sensations demand common-sense consumption.

Starfire OG

A name like Starfire OG conjures images of an almost mythical, magical being – and this strain doesn’t disappoint. An indica-dominant hybrid strain, Starfire OG may be a lesser-touted cannabis strain, but it certainly sets the bar high for quality.

Those clever breeders at Silent Seeds – who specialise in high-THC marijuana strains – have created another masterpiece with Starfire OG, which delivers high yields, dense buds, and a THC content of between 24 and 28%. It’s a tall plant, stretching to 300cm in outdoor grows, and in good hands can return a staggering 1300-1500 gm/plant. Indoor growers can expect similar delight, as Starfire OG can yield up to 650 gm/m2 of top-quality bud.

This cultivar is a citrus sensation, with lemon and lime flavours offset by a touch of fuel. The quality of aroma and taste is everything you’d hope for, but the effect exceeds expectations. Prepare for a fast onset of energizing cerebral euphoria, giving way to powerful, physical relaxation. Sounds good? Feels even better.

And now, some of the highest THC strains we’ve ever heard of….

Godfather OG

The strain known as “The Don of OGs” wears the heavy crown of being one of the most potent indicas on the planet today. This insane strain clocked in at a coma-inducing 34% THC, although some claim it’s more stable around 28%. Either way, it’s a puffer you can’t refuse.

Godfather OG came to life after Alpha OG married XXX OG, and the result is frankly nuts. It’s easy to see how this bagged Best Indica at the 2013 Cannabis Cup in Los Angeles. The taste features spicy, Kush flavours with a hint of grape in there for sweetness.

Popular with medical marijuana patients, Godfather OG is highly coveted for its pain-relieving qualities. Unsurprisingly, those off-the-charts THC levels guarantee it’s equally coveted for its insomnia-busting prowess. You’ll sleep – but hopefully not with the fishes. Godfather OG is not recommended for those with a lower tolerance to THC.

The Toad

When you think of Mike Tyson, you think of one-punch knockout power, so it should come as no surprise to learn he’s behind The Toad. Tyson Ranch, the cannabis brand co-founded by Iron Mike himself, specialise in putting out new strains with head-scratchingly high THC content, and The Toad is their flagship weed.

A mostly-indica strain born from crossing Chemdawg OG and GSC (Both already known for their high -THC content), The Toad typically tests above 30%, with some tests showing THC content as high as 36%. Yikes. That stuff hits harder than Mike.

The Toad tastes of orange, cinnamon, and petrol notes, making it a true connoisseur strain in every way. The effect is one of cerebral euphoria, which then gives way to full-body relaxation. Clearly this is an X-rated strain which should only be smoked by Willie Nelson, Tommy Chong, or Snoop Dogg. Probably.

Future #1

Okay, things are starting to get out of hand now. Future #1 is a 50/50 sativa/indica hybrid born from crossing Gorilla Glue#4 and Starfighter F2, said to pack a THC content of 37%. 37%! Do you get high just from ordering it? I hope it has medicinal properties, because my head hurts just from thinking about this one.

It’s absolutely delicious, too, with aromas and flavours of pineapple and mango. The effects of smoking a strain like this are what you’d imagine – extreme euphoria, sensory stimulation and an incredibly powerful body relaxation. But the kicker with this one is that there’s a good chance you’ll experience psychedelic effects, too. Like hearing colours. Or tasting music.

One thing’s for sure – even those with a reasonable tolerance may find this one heavy-going. 37% THC….just…….
