GMO cookies strain review

GMO Cookies is sometimes called Garlic Cookies or GMO Cookies, but don’t let “GMO” or “garlic” scare you away. This weed isn’t genetically modified; GMO stands for “garlic, mushrooms, and onions.” Don’t let that scare you away either; the flower may smell like garlic and onions, but its taste is much more delicious.

The child of two revered strains, this extremely potent weed is almost pure indica with just 10% sativa genetics. The GMO Cookies body stone is extremely relaxing, but it’s accompanied by a happy cerebral high that makes most users just want to lie back and enjoy.

The experience isn’t an instantly-sedating one (unless you hit the pipe too hard), so the bud can provide hours of blissful, calm enjoyment before the temptation to fall asleep arrives.

Effects and Side Effects

Be sure to have snacks and water close at hand before lighting up, because GMO Cookies high is notorious for lasting for hours and hours.

The strain’s uplifting euphoria hits fast and hard, working as efficiently as the neuralyzer from the Men in Black movies to erase any semblance of daily worries, cares, or stress. Some users say it provides them with a boost in creativity, but for most, the buzz is more of a blissful, floaty, untethered experience that may even verge on the psychedelic.

GMO Cookies’ total relaxation quickly spreads throughout the body, melting muscles and relieving lingering tension. Users experienced with high-THC strains may not be immediately tethered to their couch, but most are likely to find themselves locked there for hours as the head high ebbs and flows. Over time, the experience usually morphs into sedation and sleep.

This is not a strain that’s a good choice for daytime use, of course. It’s not even one that you can feel comfortable using over the weekend if you have plans to go out later that night; there’s a good chance you’ll sleep through the evening. For nighttime use, though? It’s a powerfully-enjoyable experience.

If you’re not expecting to be couch-locked, you might consider sedation to be the most common side effect of GMO Cookies. The more concerning effects, however, are associated with overuse of the weed, or its use by new smokers or those with clinical anxiety issues; they may experience dizziness, increased anxiety, or paranoia because of the strain’s high THC content.

Dry eyes and cottonmouth are also quite likely, and dehydration is a definite possibility as well. Be sure to have lots of water nearby when you’re taking a journey with GMO Cookies.

Bottom Line: GMO Cookies’ high THC content and powerful effects will get you really, really stoned, with euphoria that can be spacey and body relaxation that will trend toward sedation and sleep for most users.

Medical Conditions

The first half of GMO Cookies’ powerful punch, blissful euphoria, is what medical marijuana patients look for when they want a strain to help them deal with stress, anxiety, depression, and more serious mood disorders. They have to be careful, though, because the strain’s potency can actually make anxiety issues worse. At best, those users should start with microdoses.

Patients using medical cannabis for physical issues say that GMO Cookies is just as effective. They love its full-body relaxation and eventual sedation as a weapon against chronic and serious pain and inflammatory diseases. This weed is also often used by insomnia sufferers (to get a good night’s sleep), and chemotherapy patients (to battle nausea and appetite issues).

Flavor and Aroma

OK, it’s time to talk about raw garlic.

The “G” in GMO Cookies is what you’ll first notice when you open a jar or baggie, and you may very well notice the “M” (mushrooms) and “O” (onions) as well. Those scents mix with the pungent aroma of spicy coffee and diesel to make this strain exceptionally loud. It’s not a repulsive smell, by any means, but it’s certainly distinctive.

Thankfully, GMO Cookies doesn’t taste exactly like its aroma. The garlic flavor is mellower and tempered by the taste of coffee, cookies, and spice, creating a much sweeter taste than you’d expect. Garlic remains in the aftertaste, though, along with some earthiness.

Flavor and Aroma Ratings:

  • Earthy: 3/5
  • Citrus: 2/5
  • Fruity: 1/5
  • Spice: 5/5
  • Wood: 2/5

Cannabinoids and Terpenes

We dare you to find a strain on the shelves of a dispensary with a higher average THC content than GMO Cookies, which comes in at a startling 28%. Of course, “average content,” means the flower you purchase may be in the mid-20s, but then again, it might be even higher. This is indeed killer weed. CBD content is low.

Terpenes with the highest concentrations in GMO Cookies include caryophyllene, limonene, and myrcene; they bring the herbal and spicy flavor while also contributing to some of the strain’s medical effects.


There are two theories about who first had the idea to cross two heritage strains, Girl Scout Cookies and a Chemdawg phenotype, to create GMO Cookies. Some believe it was a Spanish breeder, others say it was the enigmatic breeder known as skunkmasterflex. When you think about it, the marriage makes sense – both strains are revered for their potency and effects.

A different version of GMO Cookies, usually called Chem Cookies, is also on the market. Divine Genetics created it with different phenotypes of GSC and Chemdawg, and it has similar effects but more of a fruity flavor.

Where to Buy GMO Cookies Seeds

If you guessed that it’s easy to find feminized seeds for such a revered strain, you’re right; almost all big-name seed banks carry it. Just some of them: Pacific Seed Bank, Blimburn Seeds, Gelato Seeds, and MSNL.

Some vendors like Royal Queen Seeds and The Seed Connect sell the autoflowering version of GMO Cookies, and many companies that specialize in clones offer GMO Cookies, including King Kong Clones and the Clone Conservatory.

Similar Strains

There’s Chem Cookies, of course. But if you’re looking a little deeper than that, Super Skunk, Alien Rock Candy, and Lava Cake are a few more to try.
