California staple OG Kush brings about a hard-hitting cerebral high and body-melting physical effects. Those looking to simply unwind or combat nausea, pain and loss of appetite may find relief with this versatile marijuana strain.

In spite of its widespread popularity, nobody seems to agree on where it came from. The most popular theory is that it’s a cross between the hybrid Chemdawg and an indica Hindu Kush variety. Others hypothesize that it came from a bag of Chemdawg seed that was then cultivated in California, perhaps giving rise to the OG (for ocean grown) in OG Kush.

While we don’t have an exact idea of this cannabis strain’s heritage, we do know that it boasts some of the most influential genetics on the West Coast—its progeny includes the likes of Bubba Kush and Fire OG. This indica-dominant hybrid also has many regional varieties: SFV (San Fernando Valley) OG and Tahoe OG are OG Kush strains that have been cultivated and perfected in their respective areas.

With a THC content that often hovers in the low to mid 20s percentage-wise, newcomers should exercise some caution. Consumers report a heavy, yet blissful high and physical relaxation that could lead to couch lock. It’s a great strain if you’re looking to go on an adventure, but don’t want to leave the house. Alternatively, other consumers report that this cannabis strain’s cerebral effects are mellow and stimulating enough to do simple tasks and activities.

OG Kush is also a favorite in the medical cannabis community. It’s noted to have a positive effect on nausea, gastrointestinal issues and moods disorders, to name a few. Additionally, it’s often mentioned as a good strain for those with Alzheimer’s disease.
