Few strains wrap all of the benefits of Sativa and Indica genes into one high-potency package better than Alien OG (also known as Alien OG Kush).

With THC content that can range from 20-28%, this weed delivers different effects depending on the user’s experience and desires. It combines a euphoric head high that can be creative or psychedelic, and a body buzz that starts out relaxing and can end up much heavier and sedating.

Some users are able to use Alien OG to help them get things done, but more are content to simply zone out and enjoy the trip.

The aroma and flavor of this nicely-balanced bud are what you’d expect from an OG strain: heavy on citrus, wood, and earth. And MMJ Patients love Alien OG for its ability to help with a variety of illnesses and conditions.


Alien OG is particularly noteworthy for its ability to deliver the type of high the user desires, as long as they’re careful with dosing.

It all begins with a head rush, hitting hard and fast. Expect pressure behind the eyes, immediately followed by powerful cerebral euphoria that erases stress and negative thoughts in a flash. From there, the effects depend on the user, their experience with high-THC strains, and what type of experience they want to have.

Uncontrolled, Alien OG is likely to provide a trippy and enjoyable few hours; colors, sounds, and time can all be pleasantly distorted without being alarming. However, users who can control their reactions to weed can often turn the head high into an energetic, motivating, and creative force that helps them get tasks accomplished.

Meanwhile, the strain is producing a tingly and relaxing body melt that can again vary with the user’s mindset and experience. Some are able to function just fine while enjoying Alien OG, while others find themselves locked firmly to the couch.

How do you determine the experience you’ll have? It’s a mix of determination, mindset, and desire; Alien OG can be what you want it to be if you have the self-control to make it so. Time spent with this strain can be productive, relaxing, social, or spacey, but only seasoned smokers can exert that type of control.

Bottom Line: Alien OG is potent and versatile. Some users will experience a psychedelic head high, while others will be motivated and energized. Some will feel a nice body buzz, others will experience couch lock. The user’s experience and desires determine the trip they’ll be taking.

Side Effects

Medical Conditions

Alien OG is as versatile for medical patients as it is for recreational users.

The euphoria and stress relief it provides is appreciated by MMJ patients who are dealing with mental health issues like depression and all forms of anxiety and stress. The focus it is able to provide some users may help them with ADD and ADHD issues. The energy boost some may experience can potentially help if they experience chronic fatigue.

That’s not all. The possibly trippy cerebral effects and strong body relaxation are appreciated by patients dealing with chronic and serious pain, headaches, and nausea, Alien’s OG tendency to bring on the munchies can help those with appetite difficulties, and the sedation it can produce with higher doses may be welcomed by people who suffer from insomnia or sleep quality issues.

Some patients call this a miracle strain.

Flavor and Aroma

Alien OG definitely inherited OG characteristics from the OG side of the family. It’s pungent, with lemon, pine, earth, and skunk scents filling whatever space you’re in; there are typical spice and hash scents in the aroma as well.

The smoke is smooth, heavy, and loaded with earthiness, along with the same lemon and pine notes prevalent in the weed’s aroma. Hash, spice, and some wood make themselves apparent in the aftertaste, although the earthiness and citrus don’t go away easily.

Flavor and Aroma Ratings:

  • Earthy: 4/5
  • Citrus: 4/5
  • Fruity: 1/5
  • Spice: 3/5
  • Wood: 2/5

Cannabinoids and Terpenes

Online resources may tell you that Alien OG’s average THC content is 18%, but we’re not sure where the less-potent flower they tested came from. You can realistically expect THC levels to be anywhere between 20-28% when you buy this strain and don’t be surprised if your flower is in the high end of that range. CBD and CBN content can vary between 0.5% and 1%.

As an OG strain, Alien OG unsurprisingly contains high levels of the terpenes myrcene, pinene, limonene, and caryophyllene, along with lesser amounts of linalool, carene, phellandrene, and terpinolene.


Alien OG was reportedly first bred in California’s Bay Area by a grower known by the handle Obsol33te, who crossed Tahoe OG (also called Tahoe OG Kush) with Alien Kush. Alien Kush is a balanced strain with moderate THC content, and Tahoe OG is a potent strain that leans heavily indica. Both contribute their Kush lineage to Alien OG’s powerful goodness.

Where to Buy Alien OG Seeds

You shouldn’t have any trouble finding Alien OG seeds since almost all major seed banks have them in stock. Vendors include MSNL (Marijuana Seeds NL), Pacific Seed Bank, Seedsman, Home Grown Cannabis Company, and Dutch Seeds Shop. Cali Exotic Shop and Cloud City Clones are among the companies offering Alien OG clones online.

Similar Strains

If you’re unable to find Alien OG, strains that deliver many of the same effects (without all of the versatility) include Motorbreath, Lava Cake and Skunk Hero. Tahoe OG is also a good substitute if you don’t mind an experience that’s more heavily sedating.
