How to Find the Strongest Weed Strains

Finding the strongest weed strains takes more than finding the highest THC strains. It takes a combination of research and understanding strain genetics. Here’s what you should consider.


Familiarize yourself with different strains and their potency levels. Look online for a strain’s THC content, effects, and user experiences with it. Take note of the highest THC strains. Pay attention if users note when a strain is one of the strongest weed strains.

Look at THC Testing

Trustworthy cannabis brands conduct lab testing to determine THC levels in their products. Our lab reports, for example, test for cannabinoid potency content, heavy metals, residual solvents, microbials, pesticides, terpenes and mycotoxins. These tests ensure a safer, more accurate strain for more reliable effects.

Consider Genetics

Research the genetic lineage of strains known for their potency. Some parent strains produce high-THC offspring. Understanding the genetic background can give you an idea of its potential strength.

Each strain varies in effect and strength. While each can pack a punch, think of it like different fighting styles. There’s the mind-bending sativa, but there’s also the body-melting indica.

Bruce Banner

It’s one of the strongest weed strains for its THC levels. Fortunately, it’s also a heavy sativa-dominant, making it perfect for use during the day.

Grease Monkey

If you’re looking at genetics for clues, Grease Monkey is an ideal option. Its parents are the already powerful Gorilla Glue and a Cookies and Cream variant. The result is an indica strain that delivers a fully-body experience. 

Take note: Grease Monkey may not be the best for those with a low THC tolerance!

Strawnana (Strawberry Banana)

While it’s an indica-dominant variety, Strawberry Banana often invigorates instead. Expect a surge of inspiration and even creativity. Strawnana stands as one of the strongest weed strains, resting at around 25% THC.

Maui Haze

Sour Sangria and Maui Haze are a powerful sativa duo that make them perfect as parent strains. The cross is Maui Mamba, a strain that offers an almost immediate buzzy effect. The apricot mimosa flavor is sure to be memorable, so it’s worth giving a try!

Godfather OG

One of the highest THC strains in existence, Godfather OG often exceeds 30% THC. The potent body high comes with a string of euphoric effects, too. Some consumers even find relief from symptoms of pain and stress with such a powerhouse strain.

Blue Dream

An easy strain to stay focused with, Blue Dream comes packed with a sweet berry taste. At around 80% sativa, the strain’s great for socializing, tackling tasks, and so much more. It helps users relax while they stay focused, so it’s perfect for evening or daytime use alike.

GSC (Girl Scout Cookies)

One of the most powerful strains for motivation and creativity, GSC is a legendary name in the industry. The cerebral pump offers energy and sweet euphoria at its peak. A tasty strain, too, there’s a reason it’s one of the most famous strains around.


Another sativa-dominant powerhouse is none other than Trainwreck. With quite the show-stopping name, it delivers a lemony pine scent that’s hard to forget. Its potency keeps the strain flying off the shelves as a fan favorite.

GDP (Granddaddy Purple)

Last but certainly not least, our PRPL Haze disposable offers a tart, juicy punch thanks to its parent strain: GDP. The utterly legendary Granddaddy Purple strain needs no introduction.
