MK Ultra Weed Strain Information & Review

You’d expect a lot from a strain named after a secret CIA mind manipulation program, and MK Ultra (also called MKU and MK Ultra OG) delivers on that promise. This indica-dominant cannabis (70%/30%) delivers some of the most potent cerebral and physical effects that any weed can offer.

The MK Ultra high starts with almost overpowering euphoria that can become hypnotic for most users. It couples that cerebral blast with deep body relaxation that usually is overpowering. Expect to be couch-locked and probably sedated. MMJ patients rely on MK Ultra for a variety of medical and health issues.

This strain is extremely skunky but its creamy smoke tastes somewhat sweet, with notes of earth, diesel, and pine. It won the High Times Cannabis Cup for Best Indica in 2003, and just missed repeating with a second-place finish in 2004.

Effects

You’d better have your munchies and water ready by the couch before you spark up a bowl of MK Ultra. This bud hits fast and hard and goes straight to the brain before slamming the body.

The cerebral high is definitely euphoric, and it’s quite common for users to become giddy and get cases of the giggles. There’s no room for stress, anxiety, or everyday concerns during the MK Ultra experience. Many smokers describe the head buzz as hypnotic, making it difficult to focus on productive tasks. Some end up just staring into space.

There’s much more to come: a surge of heavy, extreme relaxation that melts the body and makes it almost impossible to remain standing. The next few hours will inevitably be spent on the couch, enjoying the calming but still happy high — or giving in to the growing sedative effects and falling asleep.

MK Ultra is unquestionably a strain to be enjoyed at night, or perhaps on a weekend day when your schedule is clear. You may be able to watch a movie while under its effects, although there’s no guarantee you’ll be able to follow the plot or remember what you watched.

Bottom Line: MK Ultra delivers a blast of uplifting cerebral euphoria that often turns hypnotic, and a second blast of utter relaxation that’s couch-locking and often sedating. This is a powerful strain that’s perfect for getting completed wasted at night.

• Pain: 5/5

Side Effects

While MK Ultra isn’t a strain with super-high THC levels, it’s still extremely potent and may cause dizziness, anxiety, or paranoia in inexperienced smokers or those who already suffer from anxiety issues. Those folks should microdose to see how the strain affects them before overdoing things. Otherwise, the primary side effects are cottonmouth, dry eyes, and coughing.

Negative Effects:

• Paranoid: 2/5
• Dry Mouth: 4/5
• Dry Eyes: 4/5
• Lethargy: 5/5
• Cough: 4/5

Medical Conditions

Medical marijuana patients look for many different types of benefits from weed, but an enormous number of them want to be able to take their minds off of their health issues. MK Ultra’s powerful ability to relieve stress and even induce a hypnotic state is custom-designed for those patients, particularly ones with anxiety, clinically-diagnosed stress, and depression.

The extreme relaxation this strain provides is just as helpful for MMJ users with chronic and serious pain. Those dealing with the muscle or joint pain of fibromyalgia, arthritis, and lower back injury say MK Ultra delivers strong physical relief. Patients with insomnia appreciate the somnambulant effects of the strain, and it can boost the appetite of patients who need help there.

Flavor and Aroma

MK Ultra flower is extremely pungent. Even that description doesn’t do full justice to the strain’s powerful scent, which will remind you for days that you enjoyed some of this weed. It’s skunky, with lots of diesel and earth in the aroma along with a little sweetness, citrus, and what many have described as the smell of burnt plastic.

The taste of the smoke isn’t as overpowering. There’s still lots of pungency and earthiness, but it’s tempered by sweetness and lemony flavors. The diesel is most noteworthy in MK Ultra’s aftertaste, along with pine and other woods.

Flavor and Aroma Ratings:

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

Cannabinoids and Terpenes

MK Ultra is a perfect example of why THC content isn’t the only factor that determines a strain’s potency. The average THC content in MK Ultra is 20%, far from the highest level you’ll find available in a dispensary — even though its head and body highs are among the most powerful you’ll find. Our point: genetics matter, too. There’s almost no CBD in this strain.

The terpenes that dominate MK Ultra flower are myrcene, caryophyllene, and limonene, not unusual for a strain that’s indica-dominant and skunky. There are lesser amounts of pinene, camphene, and humulene.

Lineage

Amsterdam’s T.H. Seeds first bred MK Ultra by crossing OG Kush with G13, supposedly the first time a European breeder used American OG Kush as a parent strain. OG Kush, of course, is revered for its skunky diesel characteristics and powerful high that’s quite similar to MK Ultra’s.

G13 is the more interesting story. It’s also skunky and delivers a strong, stoney high, but what’s just as noteworthy is the strain’s supposed backstory: it was allegedly first bred in a government lab where scientists were trying to create the world’s strongest strain. That’s fitting for weed that’s named after a secret government LSD experimentation project.

Where to Buy MK Ultra Seeds

This is one of the rare and unique strains whose feminized seeds are available from the original breeder, T.H. Seeds. You can also purchase regular or feminized seeds from many online seed banks, including Pacific Seed Bank, Seedsman, and Crop King Seeds. A few online vendors also sell clones of this strain.

Similar Strains

Some of the strains you might want to try instead of MK Ultra include Pink Kush, Tahoe OG, Platinum OG, Biochem, and of course, parent strain OG Kush.
