Cannabis provides different kinds of buzz. Depending on what you seek — whether you need to relax or you seek to uplift your mood — there’s probably already a strain that’s out there for you. But if you’ve been consuming cannabis for a while now, you might have built a tolerance. Thus, here are the strongest marijuana strains that can give you the high that you’re looking for.

Strongest Marijuana Strains of 2023

1. Godfather OG

Godfather OG aka OG Godfather, “The Don of All Gs,” or simply the “Godfather” — when a strain has nicknames like those, you can just tell how well-loved the Godfather OG is. The Godfather OG is one of the strongest marijuana strains that are mostly Indica; it’s a cross between XXX OG and Alpha OG — two other beloved marijuana strains!

The Godfather OG has a hint of grape flavor. But the high it provides is the relaxing kind — which is perfect if you suffer from insomnia or you just want to relax! But this Cannabis Cup 2013 1st placer is extremely potent. Its THC levels can range from 28% to 34%!

2. GMO Cookies

Another favorite among indica-enthusiasts is the GMO Cookies or the Garlic Cookies. With a 90:10 indica/sativa ratio and 20%-24% THC levels, this is one of the strongest marijuana strains in the world. It’s almost always guaranteed that GMO Cookies will give you the sedating effects it’s reported to provide.

3. Ghost Train Haze

Ghost Train Haze is one of the strongest marijuana strains that’s mainly sativa — it has an 80:20 sativa/indica ratio. It’s a favorite among stoners because it can contain up to 28% THC. Ghost Train Haze is also reported to have a citrusy yet pine-like aroma.

As for the effects, since Ghost Train Haze is sativa-dominant, you can expect that your mood will be uplifted and it can very likely energize you! Therefore, this is an excellent strain for those who suffer from anxiety and depression.

4. Grease Monkey

One hybrid strain that’s best smoked after a long day’s work is Grease Monkey — you’re better off on the couch when you consume this marijuana strain because it’s known for its relaxing effects, but on a very intense level! Grease Monkey is a hybrid strain with THC levels that can go as high as 31% — that’s because Grease Monkey’s “parents” are Cookies and Cream, and Gorilla Glue.

Moreover, if you’re a real-life grease monkey, this strain might be for you — because it’s known for its pain-relieving effects!

5. Durban Poison

Sativa lovers: here’s a pure Sativa strain for you! Durban Poison is 100% sativa with THC levels ranging from 15%-30%. Therefore, if you want to keep your mind and body as busy and productive as South Africa’s Durban airport, you can try this strain.

Durban Poison is one of the strongest marijuana strains that’s also preferred for concentrate extraction due to the highly-visible resins of the buds. The flavor of Durban Poison is said to be spicy, earthy, and sweet.


If you’re not into the extremely-discernible effects of the strongest marijuana strains listed, WTF OG is also potent but with mellow effects on the body. If you wish to just chill out and relax, you can try this weed strain. WTF OG can also boost your mood as well as help alleviate your aches and pains.

7. Future #1

If you’re longing for that tropical vacation — or smoking weed on a tropical island — you can try Future #1. This marijuana strain is known for its mango, pineapple, and citrus flavors. Future #1 can boost creativity, amp up your euphoria when daydreaming, and help you become more sociable.

Keep in Mind

The strength of a high is highly subjective and varies from one person to the next. Also, these strongest marijuana strains can vary per cannabis dispensary. What’s “strong” in one cannabis dispensary may not be as potent as the others.

Furthermore, if you’ve only just started your stoner journey, it’s best that you start with strains that have lower levels of THC first — but even those who have built quite a tolerance should still be careful with these strongest marijuana strains: if you smoke too much weed, it can cause psychedelic effects or paranoia. For the most part, however, enjoy your weed!
