Packed with THC goodness

Strongest strains

If you believe the annual reports from the National Institute on Drug Abuse, weed is getting stronger. Certainly, if you measure potency by THC content, marijuana is unquestionably becoming more potent. It was even noticeable when the average THC content of weed in 2003 was 6.4% compared to just 0.72% in 1976.

One of the main reasons for this extra potency is the focus on producing sinsemilla, which is the tops of unfertilized female plants. They happen to contain the highest amount of THC. In the modern era, harvesters remove the trimmings and get rid of leaves which contain little or no THC.

It is also true that cannabis strain production has contributed to the greater strength of pot. Growers prefer marijuana strains with high cannabinoid levels, and today, the strongest selections are hybrid crosses of well-known strains. Moreover, we are uncovering stronger combinations on an almost daily basis. Back in the halcyon days of the 1960s and 1970s, finding weed with a THC content of over 10% was a rarity. Today, a significant number of strains have over 20% THC.

If you are seeking a serious high, all of the above is fantastic news. The question is: What are the world’s strongest strains in 2018? Keep reading to discover the…

5 Best and Strongest Marijuana Strains of 2018

1 – Godfather OG (The World’s Strongest Marijuana Strain?)

God Father

According to High Times at least, Godfather OG is the most potent marijuana strain on the planet. This indica dominant hybrid is reported to have a THC content of over 34%! Since it is an activated THC value, there is a good chance that the figure is conservative.

Godfather OG is cultivated by California Herbal Remedies (CHR) and is a cross of Cherry Pie, OG Kush, and Granddaddy Purps. With this information to hand, it is no surprise to learn that Godfather OG is often referred to as the ‘Don of all Kush’ strains. Even a typical strain should have a THC of over 25%.

Of course, strength means nothing without quality and Godfather OG has it in abundance. It has won the High Times Cannabis Cup for best Indica strain in the past. When you smoke this strain, it will hit you with an incredible cerebral high that soon results in euphoria. Users tend to feel happy, and soon, Godfather OG works its magic on the body. It provides you with a feeling of total relaxation and could render you immobile such is its potency.

2 – Chemdawg (The Pungent Marijuana Strain)

Chemdawg previously held the record for highest THC content; it won the coveted Cannabis Cup title with a THC level of 32.13% when cultivated by Next Harvest in Denver. It is also one of the most mysterious marijuana strains as little is known about its genetics or history. Rumor has it that Chemdawg is a cross of a Thai and Nepalese sativa.

It should go without saying that this strain is not for the newbie. It is an indica dominant hybrid (55%) that is renowned for its pungent scent which carries a hint of diesel. In fact, this strain is used to create Sour Diesel which is one of the world’s most popular marijuana strains.

When you smoke Chemdawg, it will provide you with a wonderful cerebral high that is incredibly enjoyable; once you know how to handle it! It has a powerful relaxing effect that is ideal for calming down a mind that tends to race. Furthermore, If you are stressed at work and need something to help you chill out, research shows that strains like Chemdawg is perfect because it is uplifting. However, it is also a strain conducive to creativity.

3 – Irish Cream (This Marijuana Strain is the Real McCoy)

This is yet another case of crossbreeding to yield an exceptionally powerful marijuana strain. Irish Cream is an indica developed by Mighty Irish Seeds. They crossbred Real McCoy with Cookies and Cream, and the result is a strain that clocks in at over 27% THC in many cases.

If you smoke this strain in the belief that it will taste like Bailey’s, you’re in for a disappointment as it offers classic weed flavors instead. You will find that this bud offers the taste of fresh herbs and pine; while it doesn’t taste like sweet cream, it is nonetheless a pleasant experience.

Irish Cream is an extremely potent strain which makes it ideal for treating anxiety, depression, stress, and chronic pain. The initial high is slightly cerebral, and soon, you’ll feel happy, relaxed, and sociable. Eventually, your body starts to feel the effects and you’ll begin to feel sedated. It is a carefree strain that is ideal for evening and night time use.

4 – White Tahoe Cookies (This Marijuana Strain is the New Kid on the Block)

White Tahoe Cookies

This exciting new strain was initially grown by Kush4Breakfast and is a cross of The White, Girl Scout Cookies, and Tahoe OG, so the name of the hybrid became obvious to the creator. We expect White Tahoe Cookies to become extremely popular on the West Coast. Its THC content clocks in at over 27% which makes it one of the world’s strongest.

It is an indica-dominant strain (70%) and is one of the most aesthetically pleasing marijuana strains around. White Tahoe Cookies is distributed by the Archive Seed Bank and is worth trying so that you can enjoy the sweet yet harsh notes with obvious OG undertones.

You will be shocked by just how quickly White Tahoe Cookies starts to take effect. All it needs is a single toke to understand that you’re dealing with a potent monster of a strain. Within minutes, you should feel euphoric, and your mind should become filled with great ideas because this strain is fantastic for creativity. Ultimately, you will feel a relaxing body buzz that turns into a feeling of sedation; it lasts for hours so make sure you’re safely wrapped up in bed.

5 – Strawberry Banana (The Marijuana Strain That Tastes Like Dessert)

Strawberry Banana

This indica dominant hybrid (70%) is a cross of Crocket’s Banana Kush and Strawberry Bubblegum and was developed by those crazy geniuses at Serious Seeds. It is a mainstay on the High Times Strongest Strains on Earth list. It has been on the list three years in a row and one version of the strain, grown by Greenwolf LA & Green Country Rebellion, had a THC content of 31.62%.

The average THC level is closer to 26% which still makes it one of the most reliably potent marijuana strains in the world. Strawberry Banana is known for its incredible taste which is akin to tropical strawberries. The taste is accompanied by an amazing sweet tropical strawberry scent, and a sweet banana exhale.

Strawberry Banana begins with a cerebral head high and ensures you feel relaxed and focused. Eventually, you will feel sedated and possibly couch-locked. It is a fantastic strain to handle chronic pain and according to certain studies strains like Strawberry Banana are also suitable for users suffering from depression, PTSD, or insomnia.

5 Best and Strongest Marijuana Strains of 2018

    Life Experiences

    BigDick means tinny winnie…This person person needs to inhale a lot more..This usually an act of a juicer with sour life cycle.
    Let’s wish this one a better road in the future.

  2. Aidifex

    “Caviar” is a bud rolled in hash oil then dipped in kief. We’re still around the 34% mark for strongest strain ever tested. If someone claims otherwise they’re pulling your chain or just do t know enough about what they’re talking about.

    It’s unlikely we’ll ever exceed 40% though. Think about it, greater than 40% of the bud, by volume not weight, would have to be THC and that doesn’t mean cannabinoid content.

  3. Don

    Loving Headcheese when the labs test at close to or over 30% with B-Myrcene above 10mg/g. It does the trick for my wife and I for pain and a great high. I would love to try the items on the list but we have only one dispensary in this rural town.

  4. Ted the Head

    I’m going to visit Denver soon and would like to try some new/favorite potent strains there. I enjoy the cerebral stimulation and creativity with an energetic kick. All suggestions are very much appreciated. I envy you who can sample all these treats on a daily vasis. Maybe someday my backward Hoosier state can catch up with the “up and coming” states in the union.

  5. John

    I have shapeshifter and saturn og it gets the job done

  6. Jack Herer

    For me Jack Herer is the best strains ever. It always bring me a great pleasure.

  7. Paul

    I would believe these levels of THC if a Lab report from the reported strain was included. Other then that, for all I know Trump wrote this report or should I say tweeted it.

    1. Christopher Smith

      So if Trump tweeted it or said it well it’s got to be true.

  8. Cory Finnie

    i live in michigan and been trying to get godfather og seeds and just cant find them .. are they not for sale ?

    1. Bigdick McKoy

      Are you a fucking dumbass? Of course your not going to find seeds to the strongest pot strain on the planet you dipshit.

      1. carol tolhurst
        online forum and respect.

        Insulting others is offensive and ignorant. Swearing can be humourous or offensive depending how and when it’s used. In person you’re likely to meet with someone’s knee in the groin if you spoke to them in this manner so show a little class. Smokers respect and learn from each other. If you have information to share do it with grace or don’t do it at all.

      2. Geoff Spicoli

        You seem to be kind of an angry prick for the Laid Back Pothead crowd? What’s wrong, buddy?

      3. Jay
        Weed - 1 Bigdick - 0

        Let me guess big dick, your 17 years old and still have no clue what intelligence or respect is, online or offline. You have a lifetime to get along with people and you wont go far unless you can figure that out genius. TIP: only dumbass people like to use stupid fucking idiotic names such as bigdick. Please help make the world a better a better place by educating yourself and being respectful to people around you. You know I love weed and everything about it, but when I have to read a comment such as yours in a place where I expect people are cool, your comment is rude, offensive, childish, unthinking, simple minded, disrespectful, waste of time, pointless, ….I mean nobody thinks your comment is cool or acceptable in any way but if you think it is…the dumbass is you.

      4. Kc
        2 cents

        mandatory: Internet should post your real name and photo….I wonder how the internet would run?

      5. Ray Brown

        McKoy, you haven’t gotta be rude to Mr. Finnie. A simple no, and probably won’t, would have been sufficient and sounded a lot better, not to mention more intelligent. Not being smart, just being truthful. 😉

      6. Tee

        Yeah thats the way to answer someone .. dick !! Fucking people are rude as hell online .. seem them in person and its nothing but humble pie … smh clown

  9. Chris

    Trying the chemdawg next

    1. Ray Brown

      Me too…

  10. Some guy

    I purchased an indica-dominant strain called “The White,” from two separate Oregon dispensaries. This strain was listed as having 33% and 34.03% THC. I haven’t tried most of the strains listed here, but I can say that at most of the dispensaries I visit, anything under 20% usually goes in the $4 gram/$30 ounce bins. The White has been the highest I’ve seen, though I did a pre-roll yesterday that was 28% (dawgie treat), and I have seen a few others in the 29-30 range.
    Anyway, thank you for the post

    1. Boomhauer

      Some guy is bullshittn. I been around blue cookies bubblegum white fire durban all types of cookies pies and ogs from cali and nothinf he said was true. Lame ass.

  11. Potmobile

    me thinks they have to be synthetic to achieve those levels. Any proof they are not?

    1. SyntheticDeez

      Really? I’ve never seen a synthetic bud before… how would they make them? When did MJ become a designer or ‘club’ drug? Only synthetic wanna-be MJ I have ever seen is in powder or clumps of powder… when did they start making whole buds and plants in a beaker? (I ask because of the big pics of buds posted for each strain) You, my man, are so retarded…………..
