There are plenty of cannabis strains out there that’ll put you on your ass and in the couch. Some have super high THC content, with minimal terpene levels; others are the exact opposite with average THC content, but wicked terps on deck; most fall somewhere in the middle. Choosing which of them rank amongst the strongest ultimately comes down to your personal experience with cannabis and how your body reacts to it.

How Do You Know Cannabis Potency?

When discussing the strongest cannabis strains, it’s important to remember 3 things:

  • The effects of cannabis are between you and your weed. We all have our own endocannabinoid systems, and they all work differently, so what hits me in the gut like a sledgehammer might be a faceful of daisies for you.
  • It’s impossible to cover EVERY super potent cannabis strain that exists in the world, meaning there’s no true way to rank them, however, there are plenty of if-you-know-you-know weed strains out there that we all agree are not for the lighthearted and weak-lunged.
  • THC CONTENT IS NOT EVERYTHING. While true THC is the cannabis compound most known for getting you high, the highs you feel when smoking result from a combination of many factors: who grow the weed, how and where it was grown, and the chemical makeup of whatever was grown i.e. their cannabinoid and terpene profiles.

That said, here are 7 of the strongest cannabis strains in the game.

The Strongest Cannabis Strains

Blackberry Kush

Blackberry Kush is one of the most night-night cannabis strains in the whole strain-o-sphere. Every single time I smoke it, the first couple puffs are already enough to put me to bed for hours. Blackberry Kush’s genetics are unconfirmed, though it’s widely believed this indica-dominant strain is of Afghani descent. It tastes like berries and gas, which is common amongst many of the cannabis strains known to be potent, relaxing, and sleep-inducing. Novices should steer clear of Blackberry Kush.

Skywalker OG

Skywalker OG is a cross of OG Kush and Skywalker, which is a cross of Mazar and the well-known Blueberry. Many strains with Blueberry genetics are super strong, thanks to Blueberry’s potent and relaxing nature. It’s why even Blue Dream (Haze x Blueberry), thought to be the ultimate sativa-dominant hybrid with uplifting effects, can still be potently relaxing if consumed in higher doses. That said, Skywalker OG will kick your ass if you underestimate it. It’s a sweet treat with berry, floral, and diesel notes and the effects leave most people feeling relaxed, sleepy, and sedated. Zzzquil has 24 hours to respond.

GSC (formerly known as Girl Scout Cookies, commonly shortened to just Cookies) and pretty much anything with its genetics are going to be extremely potent. Thin Mint, Do-Si-Dos, Gelato and it’s many phenotypes put the proof right inside the pudding. GSC was bred by the Cookie Family, who are notorious for divulging little information about their work, so again, another strain with unconfirmed genetics. But we believe it’s Durban Poison and OG Kush. What we do know is the strain is known for being extremely potent with uniquely earthy and gassy terps that can stop any cannabis connoisseur in their tracks. The legend of GSC’s potency has set a whole new bar for California cannabis over the past decade.

Original Glue

Original Glue is any other strain that had to change its name for legal reasons. Originally known as Gorilla Glue #4 (GG#4), this potent strain was bred by a complex mix of Chem’s Sister, Sour Dubb, and Chocolate Diesel. Cool, enough with the history lesson, let’s talk about effects. The strain is named Glue because the effects leave you glued to the couch, and anyone who’s smoked this earthy and funky flower can attest to that. Relaxed, sleepy, and happy are the top 3 most common effects felt from smoking this strain, which is just dictionary-talk for wow, Original Glue gets you stoned out of your mind.

Death Star

Death Star is a potent indica that should only be consumed if you are built for hours and hours of being so stoned that you can’t function. That’s just straight up truth. Most people say this cross of the famous Sour Diesel with Sensi Star makes them feel extremely relaxed after smoking Death Star, but right after that is paranoia. Because it’s one of those strains where if high THC content sends your brain on a rollercoaster ride, then you will most definitely be overwhelmed by its strength. Some Death Star batches have tested as high as 35% THC.

True OG

There are plenty of OG Kush-related strains that could be on this list. True OG is continuously one of the most potent choices. True OG is thought to be the cross of an OG Kush with an OG Kush that was crossed with another OG Kush until the breeder finally had the perfect indica-dominant OG strain. If you want a weed strain with relaxed effects that will help quiet the world around you, this one’s an excellent option, especially as dabs. Those sweet and earthy True OG terps really pop in concentrate form.

GMO Cookies

You’ve probably gotten to this point and wondered where Chemdog is. Yes, Chemdog grandmothered the entire gassy game when it comes to those diesel-flavored strains. And in the decades since its birth, many other super potent wham-bam-thank-you-mam strains have carried on its legacy. GMO Cookies is the newest. GMO Cookies crosses the old school Chemdog with the new school GSC to give you a strain whose THC content consistently soars past 20%. And the terps? Loud. Screamers. Soon as you open a GMO jar, you start to look at the day’s to-do list like “Hmmmm, yeah, I should probably clear this before I smoke that, cause WHEW.”
