Which Is the Most Potent, Strongest Weed on the Planet?

With at least a thousand cannabis strains available to choose from, deciding what strongest weed out there is might be a tad bit difficult. 

Regular weed users make their choice over potency, effects, and taste, but there are also the cultivation methods, health benefits, and aromas that play a part in how strong a weed is.

Although we cannot settle on just one cannabis strain, what we can do is make a list of the most powerful weed strains. The experienced are invited to make their pick, newbies are advised to wait until they get some notches on their belts. 

What Is the Strongest Weed Made Of?

Bear in mind that even though potency is mostly linked to THC content, it isn’t just high tetrahydrocannabinol levels that show how potent a marijuana strain is. 

Other compounds in the cannabis plant’s chemical makeup such as cannabinoids and terpenes, also play a role in its potency. And the factor list doesn’t stop there! 

Determining how high you can get is also your individual physiological response and innate body chemistry. Plus, there are also the conditions of keeping or the quality of your bong.

That said, let’s dive into the most powerful marijuana strains listed by their dominant types (Sativa of Indica).

Strongest Weed — Hybrid Weed Strains

The White

An Indica-dominant hybrid with 23% THC, the White is named after its trichome-covered buds, which are full of resin glands and make this plant look like it was rolled around in the sugar.  

But it’s not just its appearance that is distinctive. The White strain is also known for its lack of odor! The quality makes it a popular choice for those wishing to avoid more pungent alternatives, but still taking some of the strongest weed available.

With its calming effects on the body and the head, this weed strain is recommended for the treatment of muscle spasms, headaches, nerve pain, and stomach issues. Also, because of its sedative effects, it is recommended as a mid-day or nighttime strain. 

Gushers

A hybrid that is 60% Indica and 40% Sativa, and one of the strongest types of weed, Gushers is a cross between Gelato and Triangle Kush. Named after the delicious, juice-filled candy, Gushers is an extremely potent strain with 15 to 22% THC and almost no CBD, so not suitable for novice users.

It looks like a pine cone, with the exception of dark-green and purple colors, and it smells and tastes sweet and creamy, with undertones of sour tropical fruits. 

Be warned: Gushers strain has incredible relaxing properties that can knock you out for the whole night. Although one of the strongest marijuana types, it is not sleep-inducing; meaning, this weed will put you in such a deep state of relaxation that you wouldn’t care if the house was on fire! 

Gushers also boosts appetite, so have some food around if you are planning to indulge in this particular marijuana strain. 

Lemon Cookies

A perfectly-balanced hybrid strain, Lemon Cookies is developed from Girl Scout Cookies and Lemon Haze. 

Known for its neon green nugs with orange hairs, the said strain has a sweet lemony flavor and scent, combined with a spicy cookie overtone. 

When discussing the strongest weed in the world and its effects, Lemon’s are not as bright and explosive as its aroma and taste, but this cannabis type is still a huge mood booster.

 It promotes euphoria, but it’s not overwhelming as it relaxes your body and releases all the built-up tension and stress you have accumulated. 

The Lemon Cookies strain is rich in THC (between 21% and 28%) making it just right for those dealing with mood swings, inflammation, fatigue, and depression. 

Starfigher 

Starfighter isn’t the highest THC strain around as it only has 15% to 20% THC, but it makes up for it with a lemony pine aftertaste that can linger for hours.

 A cross between Alien Tahoe OG and Lemon Alien Dawg, this is an uplifting strain that will make you feel like you are soaring while causing extreme couch lock and relaxation. 

With medium-sized nugs and dark purple leaves, and a coat of star-like trichomes, the Starfighter strain is best grown indoors. 

Additionally, Starfighter is one of the best weed strains to treat the effects of chronic pain, depression, and anxiety. 

Chemdog 

There’s nothing subtle about this weed — from its pungent, diesel-like smell, to its high that heightens creativity while leaving the body stoned and relaxed. 

With 19% THC, Chemdog might not have the same THC levels as other weed strains, but it is amazingly potent and not suitable for new users, or novice growers for that matter. 

It is quite difficult to cultivate, but definitely worth a shot as it provides a nice yield of potent buds. Chemdog was proclaimed one of the best for 2019, with high hopes ranking among best weed strains in 2020. 

It has been around for quite some time too! Legend has it that a man named Chemdog bought some weed at a Grateful Dead concert in 1991 and took a liking to it. 

He bought some more and started growing it, thus creating this incredibly popular plant, which is also the parent of some other well-renowned strains such as Sour Diesel and OG Kush. 

This strain of marijuana is perfect for fighting arthritis, ADHD, migraines, and PMS and is most certainly the best and strongest weed in the world. 

Sour Diesel

As the name suggests, Sour Diesel is recognizable for its pungent smell of fuel, skunk, and citrus, as well as its sweet, musky flavor. 

A Sativa-dominant hybrid with “only” 19% THC, Sour Diesel provides a fast-acting, energetic buzz that heightens creativity and gives an uplifting cerebral high. Because of this, it is not recommended for patients suffering from insomnia, but rather for nerve pain, chronic fatigue, or fibromyalgia. 

Said to be the child of Chemdog 91 and Super Skunk, this is one of the best weed strains for sex, at least according to anecdotal experience. 

Sour Diesel grows well indoors, but you need a warmer climate if you want to grow it outdoors as this weed is used to the hot California sun. The buds it produces have a strong scent while flowering. 

Apple Fritter

The Californian Lumpy’s Flowers created what is now considered a part of the best strains of weed for anxiety ever. Apple Fritter inherits the fast-hitting effects and delicious apple pastry notes from its parent strains—Animal Cookies and Sour Apple.

There’s no doubt that this strain will take you a creative and comforting sweet and earthy ride, which can result in sleep, so if physical and mental comfort is what you need, don’t hesitate!  

Girl Scout Cookies 

Perhaps the most famous marijuana strain in the world, this classic California weed is developed from OG Kush and Durban Poison. 

Declared as one of the best in 2017 and looking forward to joining the best weed strains for 2020, Girl Scout Cookies is a hybrid with 60% Indica and 40% Sativa.

 It brings the best of both worlds — a powerful high that combines happiness and euphoria with a feeling of deep relaxation. 

Add the sweet, minty taste, the spicy and chocolate aroma, as well as the high THC content of up to 28% to the mix and it becomes clear why this is the best selling weed on the West Coast. 

On top of that, it is the strongest weed in California for medical marijuana users, favored by patients who are troubled by nausea, pain, and appetite loss. 

GSC is a big plant that needs a lot of space. It’s not the easiest type of marijuana to grow, but it does produce a large yield, so it’s definitely worth the effort! 

Grease Monkey

This strain is a genetic mix between Gorilla Glue (GG#4) and Cookies & Cream strain. Grease Monkey’s THC and terpene combo reserves a powerful comforting hit for all those searching to accelerate the hazy, relaxing end-of-the-day feel. 

Plus, this variety’s strongest cannabis strain can count up to 27%. Even the average (25% THC) will give you a break from chronic pain, headaches, migraines, and ease your way into a calm sleep. 

Grease Monkey’s rich genetics give out an earthy mix, with vanilla and diesel undertones, a specific taste that lingers on. Depending on your weed experience, the effects can swarm you up quickly and suddenly and leave you couch-locked, which is an expected trait of the strongest weed strains for sure. 

One thing is sure—Grease Monkey will hit you hard and give you the munchies, so you’d better plan ahead. 

Green Gelato

Just like ice cream (gelato in Italian), this slightly Indica-dominant strain has a delicious dessert-like sweet taste. The deliciousness of its buds comes as no surprise, given its origins from some of the tastiest and strongest marijuana strains — Girl Scout Cookies and Sunset Sherbet.

No doubt, Green Gelato will win you over with its sweet scent, creamy tones, and citrus undertones, but what will make you keep coming back is its mind-blowing potency. 

Despite being a balanced Indica/Sativa strain, Green Gelato averages at an amazing  27% THC! Therefore, many dub this 2020-originating cannabis plant as the strongest marijuana strain around. 

The sweet-smelling euphoria that will hit you with this strain, turns into a sleep-inducing relaxed high — excellent for winding down after a long day. 

Adored by insomniacs and pain-sufferers. Green Gelato is grumping popularity stairs to the top of the most beloved cannabis strains for 2021.

Sunset Sherbet

Sunset Sherbet is not an insanely THC-powerful strain, given that its tetrahydrocannabinol content can go up to 20%.

But what makes it part of the best weed strains is that it offers an unforgettable buzz-trip that is uncommon among the heavy Indica-leaning (85% /15%) hybrid marijuana strains.

Indeed this strain’s effects start off with an upbeat, euphoric high that will have you buzzing around, and creatively planning your next move in life, just to lure you into the couch for the second episode — a deeply relaxed weed-lock.

So to speak, Sunset Sherbet is a solution for both health-seeking potters and stoners. 

That said, its pungent sweet and earthy tones might come off as strong for some—definitely not a beginner’s “cup of tea.”
