Hardcore OG (also called Hardcore OG Kush) is a hybrid with somewhat mysterious origins. Some report it as a cross of a Skywalker OG female with an unknown Kush male. It’s currently cultivated by California’s West Coast Cure, which claims the strain is a strong sedative with gassy, earthy kush flavors. It's been referred to as a heavy hitter.

West Coast Cure uses this strain to create its Hardcore OG badder, which was named best concentrate at the 2012 High Times Cannabis Cup in San Francisco.
