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

With at least 780 cannabis strains to choose from, deciding what the strongest weed out there is might be a tad bit difficult. Just as no two snowflakes are alike, no two weed strains are the same. Factors on which they differ include potency and appearance, as well as the different cultivation methods, effects, aromas, and tastes.

Although we cannot settle on just one marijuana strain, what we can do is make a list of the most powerful weed strains. So, if you are an experienced user, feel free to take your pick.

Still, if you are, in fact, a newbie, it might be best to stay away from some of these strains, at least until you get some notches on your belt.

What Are Strongest Weed Strains 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 of the cannabis plant, such as cannabinoids and terpenes, also play a role in a strain’s potency. Not to mention more factors, including physiological responses and innate body chemistry that determine just how high a user can get.

So, without further ado, let’s dive into the list of some of the most potent marijuana type (listed in no particular order).

The Strongest Sativa Strains

Ghost Train Haze

This sativa strain — named after one of the strongest marijuana strains on earth back in 2012 by High Times — is a cross between Ghost OG and Neville’s Wreck. With THC content of 25.5%, it packs quite a punch and is not suitable for beginners.

A bright green plant with dense buds covered in white, crystal trichomes, this strain has a tart citrus aroma and flavor, followed by earthy, floral tones. It produces quite a big yield (from 550 to almost 900 g/plant), especially if it is grown indoors.

A regular on the list of strongest strains of weed, Ghost Train Haze gives users an energetic, cerebral high with added vigor and a buzz of creativity. Like other high-THC strains, it is great for battling appetite loss and depression.

Nevertheless, people suffering from anxiety should steer clear of this marijuana strain as it can provoke intense feelings of paranoia.

Bruce Banner

Just like its namesake’s alter ego, i.e., the Hulk, Bruce Banner weed is big, green, and powerful.

Named the highest THC strain in 2017 (it has an incredible 29% THC content), this weed gives users an instant burst of euphoria and energy, before eventually relaxing the body. Bred from OG Kush and Strawberry Diesel, this strain has several phenotypes, Bruce Banner #3 being the most popular.

With its dense buds and leaves that turn a wonderful magenta, this plant is a delight to behold! Not to mention that it gives off a variety of scents and tastes that are predominantly lemony, hashy, and wonderfully spicy.

Recommended for its medical (it’s one of the best weed strains for treating stress and depression) and recreational use, Bruce Banner is unbelievably popular in the US.

Strawberry Cough

Another aptly named strain, Strawberry Cough is known for its sweet smell and thick haze that can make even the most experienced user cough.

The plant is medium-size, easy to grow both indoors and outdoors, and provides great yields. It has small, dense buds covered in red hairs and trichomes that make it look like the fruit it was named after.

But, don’t be fooled by its sweet name and flavor! This strain is one of the most potent weed strains on the market with THC content ranging between 25 and 26%.

The high this strain gives is uplifting and fills you with happiness — hence why this weed is highly recommended for relieving stress, depression, anxiety, and nausea.

Laughing Buddha

Giggles are guaranteed with this heavy-sativa strain. The love child of Thai and Jamaican, Laughing Buddha strain has a sweet, fruity scent and flavor and grows tall and big both indoors and outdoors. Flowering time is between 70 and 75 days, and the result is — strongest weed, as well as a heavy yield of frosty buds that are 22% THC and 1.6% CBD.

A perfectly named strain, the Laughing Buddha is recommended for treating symptoms of depression, fatigue, and stress. The strain has won many awards in the past and was proclaimed one of the best sativa strains in 2003 and 2016.

Chem Berry D

This cross between Chemdog and Strawberry Sour Diesel has a high THC content (up to 32%), making it a strain cannabis newbies should definitely stay clear of!

The highest THC strain hits both the body and the mind and can last for hours on end combining a feeling of euphoria and creative happiness. What’s more, Chem Berry D has an interesting terpene profile that delivers a sweet and fruity flavor accompanied by more chemical, diesel-like scents.

Patients suffering from anxiety, appetite loss, and mood swings would benefit the most from this particular weed strain due to its high THC levels.

Blue Dream

Have you ever wondered what state has the strongest weed strains? While it might be difficult to decide between the huge marijuana taxpayers such as Oregon, Colorado, and California, according to users, it is the Golden State that takes the crown!

In addition to popular weed strains, such as GSC and Sour Diesel, there is also Blue Dream, a sativa-dominant weed that gives a relaxing, easygoing high. It’s perfect for daytime use as it relaxes you, but still leaves you functional enough to be productive.

One of the most famous, best selling, and strongest weed strains for 2020 in the US, it has a great blueberry smell with undertones of vanilla and mango as well as a nice sweet berry taste which it gets from its genetic background — Blueberry Indica and Haze Sativa. Blue Dream buds are dense with neon green nugs covered in blue hairs and they contain 17 to 24% THC.

This weed is one of the best strains of all time for novice and senior users alike and is great for treating symptoms of depression, nausea, and pain.

Most Potent Weed — Indica Strains

Death Star

An all-powerful cross between Sensi Star and Sour Diesel, this indica dominant strain (21% THC content) was first developed in Ohio in the early 2000s. The Death Star strain cannot blow up planets, but it can put you in a state of carefree, relaxed euphoria, which makes it great for treating symptoms of anxiety and depression, as well as insomnia.

A frosty looking plant with orange and red pistils, this strain has a pungent smell and a citrusy, rubbery flavor.

Since it was rated as the 10th strongest weed strain in 2018, caution is advised when using this cannabis strain as a beginner seeing how it is extremely potent with a high that starts off deceptively slow but can soon become too overwhelming.

GMO Cookies

Another high-THC (over 25%), indica-dominant strain, the GMO strain has powerful sedative effects.

Developed from Chemdog and GSC, it is a dark green plant with many different aromas and an earthy, garlicky taste. This strain is great if you are looking to alleviate symptoms of stress and chronic pain. It is one of the best strains of weed for anxiety because consuming it will leave you feeling relaxed, happy, and totally famished too.

Due to many negative feelings some people have regarding GMOs, this strain is also known as Garlic Cookies — a name given by dispensaries fearing consumer pushback.

Godfather OG

Also known as the “Don of all OGs,” this indica strain has dense buds covered in trichomes and is recognizable for its piney, earthy aroma and taste, sweetened with notes of grape.

Another recognizable feature of this strain is its high THC content which can range between 22 and 25%, giving Godfather OG weed incredibly powerful sedative properties. In fact, this strain hits hard and fast, instantly putting the user in a state of deep relaxation.

It is the sedative qualities of Godfather OG that make it one of the most popular medical marijuana strains used by people suffering from insomnia, mental stress, anxiety, and chronic pain.

A cross between indica Bubba Kush, indica L.A. Confidential, and indica Granddaddy Purps, Godfather OG was proclaimed Best Indica by High Times in 2013, as well as the strongest strain in, and will probably be the strongest weed strain in 2020 as well!

Kosher Kush

The only weed strain to be blessed by a Rabbi, Kosher Kush is a multiple Cup winner that is known for its familiar and pungent smell of earth and fruit. Considered by many as the tastiest smoke out there, the Kosher Kush strain hits you hard and long.

As a result of its high THC content (21%), this pot offers relief from depression, anxiety, and insomnia. In fact, many smokers report that they had a long and peaceful sleep after taking this type of marijuana.

Constantly on the list of strongest cannabis strains, Kosher Kush is one of the best indica strains ever!

Grand Daddy Purple

Introduced in 2003 in California, this strain, which has a 23% THC content, is still fairly popular today, mostly due to its recognizable taste that is known to linger on the tongue. Belonging to the most famous purple weed strains, GDP is pretty potent as it fixes your body in place by relaxing it to the extreme, allowing your mind to travel around in a dreamy buzz at the same time.

Pretty looks are a trait of this strongest weed too. Grand Daddy Purple has a distinctive look — its purple hues are a stark contrast to the white crystal resin covering the plant.

With its fruity and earthy aroma (courtesy of its parent Purple Urkle) and its oversized buds (from its other parent, Big Bud) this indica-rich strain is usually chosen by users who need help managing stress, insomnia, appetite loss, pain, and muscle spasms.

Bubba Kush

Are you looking for the highest THC strain ever that will relax your body and transport your mind into a dreamy euphoria? Then Bubba Kush is the strain for you! Thanks to its high (27%) THC content, this weed is perfect for treating insomnia, depression, and ADHD. Still, care is advised as it is not suitable for daytime use nor is it the right fit for people who are not used to indica strains and the hit they give to the users.

Bubba Kush is considered one of the best strains of weed in the US and across the world as well. Its recognizable purple buds, sweet, hashish taste with undertones of chocolate and coffee are reasons enough for it to belong to the most popular marijuana strains out there.

Gorilla Glue

Gorilla Glue is an extremely potent, sticky weed strain (it produces a massive amount of resin) that many a user adores due to the soothing sedative effects and the light head buzz it gives.

With buds that can produce up to 30% THC, this weed will be one of the strongest strains in 2020!

Its earthy flavors of lemon and pine, as well as its somewhat sweet, coffee and moss aroma, make Gorilla Glue the perfect nighttime weed for recreational and medical use (it treats anxiety, menstrual cramps, and pain the most).

Another thing that makes this strain so appealing is the amount of buds it produces (up to 600 grams/m2). It can be a bit tricky to harvest, because of all the resin it has, but with such a big yield and such potent hits, it’s well worth the trouble.

Strawberry Banana

Looking forward to being listed as one of the strongest strains in 2020, this weed is a genetic cross between Banana Kush and the strawberry phenotype of Bubble Gum. Recognizable for its sweet, fruity flavor and smell, this marijuana strain is popular due to its high resin production and THC-content (as high as 26%).

This indica-dominant cannabis strain is easy to grow and produces large yields, especially if suitable nutrients are provided.

Strawberry Banana provides an uplifting sense of happiness that doesn’t impact your functionality, but it can affect your productivity. Its high THC makes it one of the best weed strains for anxiety, stress, and depression.

The Strongest 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 sugar.

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

This plant is known to grow quite tall — hence why early topping is recommended. Its yield is small to moderate, with buds that have a piney, hashy smell, and spicy taste.

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.


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.


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.


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 strain on the planet.

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.

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, and 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 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!

Final Thoughts

Ever since man first discovered the sedative, psychoactive, and medicinal properties of marijuana, stoners have been on the hunt for a more powerful hit. Today, you can even get paid to smoke weed — what a time to be alive!

Hopefully, this list of the strongest weed types in the world will help you find the best marijuana strain for you, whether you’re looking to add some more potent plants to your weed garden, or you need something stronger to treat a medical condition.

There are hundreds of cannabis strains out there that are only getting stronger. What makes our strongest weed selection so powerful? A mixture of influences.

The Strongest Weed Strains on Earth

At the start of 2016, we examined the six HIGH TIMES Cannabis Cups from the previous year and the thousands of entries they tallied. The goal? To ascertain exactly which of the entries deserve to be called the strongest strains on planet Earth. There are many types of weed strains with varying levels of THC. Our goal was to determine the strongest weed strain.

In years past, we’ve built our “Strongest Strains on Earth” list simply in order of potency. We’ve reorganized the article to categorize these potent strains by their place of birth. (Readers enjoyed this format last year, so we’ll use it again.) These rankings represent only one data point: THC potency, as determined by lab testing. They do not include the judges’ scores or notations, or any other cannabinoids or terpenes (the latter can be read about in our new annual feature, “The Best-Tasting Buds on Earth”). However, this year we’ve included a short list of the strongest CBD strains from 2015 to complement our THC charts.

So if you’re looking for a strain with a knockout punch, one that will get you high when you’re feeling low—you’re in the right place!

The Emperor Cookie Dough, a cross between Emperor OG and Girl Scout Cookies, was entered into the Denver US Cannabis Cup by the Greenwolf LA crew and is one of only two strains ever to cross the 30% threshold for THC. The other strain to do so? Keep on reading….

Karmasutra , a collaboration project, is a hybrid of the Karma OG crossed with Rockstar . Rockstar has two known versions: The Canadian version is a Bubba Kush x Lemon OG , while the European version is Rockbud x Sensi Star.

Veganic Strawberry Cough has been included in our “Strongest Strains on Earth” compilation (hereafter, The List) for three out of the five years that HIGH TIMES has been running it. In 2012, the VSC maxed out at just over 20% THC. Meanwhile, veganically grown strains (using Kyle Kushman’s Vegamatrix line) have made The List seven times over the course of those five years.

It’s no surprise that this year’s strongest strain—and the new record holder for the highest potency ever recorded at a High Times Cannabis Cup event—is none other than Chem Dog. Reaching 32.13% THC, the Chem has achieved what most of us thought was impossible and leaves us asking one basic question: Just how high can a flower go in terms of potency?

The Brotherhood was another organically grown entry that hit nearly 28% THC. Propagated from seed, her lineage stacks up like this: (Willie’s Wonder x Grape Krush ) x (Bubba ’91 x The White).

The Sour Kush was grown under a purple LED light, and she still went over 26% THC. Does this mean that limited-spectrum LED lamps are healthy for plants—or that the plant was stressed, producing more resin to attract pollen in order to ensure its survival? And if the latter, do you care? The debate continues ….

The Ghost Train Haze appeared in our very first “Strongest Strains on Earth” feature, taking the prize for the most potent strain of 2011 at 25.49% THC. In 2014, she was our THC champion again at nearly 27.46%. Entered last year by the fine grow team at Greenman Cannabis in Denver, the Rare Dankness–bred strain dipped slightly, but we suspect she’ll be back again next year looking for the top slot.

Chiquita Banana, a relatively new name in the fruity strains, is likely a backcross of the Banana Kush (or Banana OG ) out of NorCal , with her potency derived from one of her parents, the epic Ghost OG cut.

Appearing twice on The List for 2015, the Strawberry Banana also was named one of “The Strongest Strains on Earth” in 2014, coming in at 22.51% THC. Additionally, she recently showed up in our “Best-Tasting Buds” feature (March ’16) boasting a very prolific terpene profile. A cross between Bubblegum and Banana Kush ( OG ), the SB goes nine weeks in flower.

Gorilla Glue #4 has been steadily gaining in popularity over the past few years, combining a unique flavor with a very potent high. A super-cross of Sour Dubb x ( Chem’s Sister x Chocolate Diesel), she’s a sativa-dominant hybrid that’s been making her way across the country, and has reportedly even been seen on a menu or two in Dutch coffeeshops .

The Sunny Days doubtless gets her potency from her father, the Ghost Train Haze #1. This particular sativa-dominant hybrid is a GTH backcross whose lineage is represented as (Grape Stomper x GTH #1) bx GTH #1. This entry, hitting nearly 27% THC, was organically grown.

Death Star has been around for a while, but the Sour Diesel x Sensi Star cross has never quite lived up to initial expectations. This pheno , however, achieved new heights when grown in all-natural soil and organic nutrients from the Detroit Nutrient Company. See a trend?

Sunshine #4, an OG x Cherry Pie x Pink Panties cross, first made headlines in our “Best-Tasting Buds” feature this past March, boasting 2.2% total terps , with myrcene heading the roster. Combine that with nearly 26% THC, and you get a potent flower that took home first place in the Best Hybrid category.

2015 Cannabis Cup: Jamaica Cup

Category: Sativa Flowers (Outdoor)

% THC: 15.4

The Jamaican Cannabis Cup featured entries grown only in Jamaica, with the categories divided into Indoor, Outdoor Sativa and Outdoor Indica for flowers. The average indoor flower potency was 15.5% THC. Out of 53 total flower entries, the average outdoor potency was 10.1% THC for indicas and 10.4% THC for sativas . These averages represent the values for activated ( decarboxylated ) THC.

Each province or parish of Jamaica is represented by a primary ganja growers’ association, and many of the entries were supplied via these organizations. Rastafarians comprise a majority of these growers and have been cultivating some of these strains for many decades. They were central in organizing this Cup competition.

St. Bess Ganja Growers, which provided two of the most potent entries in the Jamaica Cup, as well as the St. Ann’s Botanical & Agro Processing Cooperative and the Orange Hill growers (of Westmoreland), were among the top associations of island cultivators.

The True OG was grown from seeds purchased from Elemental Seeds.

Eight of the 26 entries in the Best Indica category, or 31%, tested for high CBD levels (over 3%). The highest was 9.2% CBD , in a strain called Black Willy from the Accompong Maroons, Jamaica’s oldest indigenous people.

Strongest CBD Strains

As THC potency rises, so too come increasing CBD levels. We never thought we’d see the day when CBD actually catches up to THC, but that sentiment is now being challenged as we witness CBD strains crossing the 20th percentile for the first time ever.

In comparison with the results in the THC category, the CBD strains were tested by three different labs across four separate competitions, with values coming back between 15% and 21%. The top CBD strain, a Cannatonic phenotype that’s been circulating in the northern US for the past several years, also hit 19% CBD at the Michigan Cup in 2011.

Mile High Has Record High

This feature has been running annually in our hallowed pages for five years now. The previous high mark for potency was 28.35% THC for the Bruce Banner #3, set in 2013 at the Denver Cannabis Cup. Since that time, we’ve discussed at length just how high a cannabis flower could go, physiologically speaking, in terms of THC. We’ve also discussed the various lab-testing methodologies used by labs in different states. We asked the experts if we would see an end to these skyrocketing values, or would cannabis simply continue to progress until we had buds testing at over 50% THC? The truth is, there has to be a ceiling at some point: After all, a flower can’t be 100% percent THC.

In 2015, we reached a new milestone in the Mile High City, crossing the 30% threshold for the first time ever at a High Times Cannabis Cup competition. Sure, we’ve heard rumors about strains climbing as high as 35%—we’ve even examined reports submitted by growers and prepared by no-name labs. But these reports won’t be considered valid until we can certify the lab and its testing protocols, as we do for each Cup competition we hold.

In Denver, we had not one but two flower entries break the barrier and cross into a new realm of cannabis potency. And while both were entered in the same Cup, they were grown in different states, by different growers, using different genetics and techniques. Still, it’s important to remember that while we validated the testing methods used, we had only one lab running samples at this Cup, as opposed to our normal protocol of two separate labs running the samples independently.

Greenwolf , a celebrated LA dispensary, brought to the Denver Cup their Emperor Cookie Dough, which tipped the scales at 31.1% THC—an impressive number, to say the least. And then we have our good friends at Next Harvest, a perennial contender from Denver, whose Chem Dog cut surpassed the 32% mark and set the bar with a new all-time high of 32.13% THC.

This comes as no surprise to anyone who’s ever smoked a pure Chem Dog, which just happened to originate from seeds found in a pound of cannabis grown in Denver in the 1990s (and known simply as “the Dog” back then). Today, we no longer question the results, but instead celebrate the unknown. And one day, sooner or later, our questions will finally be answered as to just how high this precious plant can take us.

We’d like to pause here and thank our partner labs for providing such excellent and thorough lab results for our Cannabis Cup competitions in 2015:
