OG Kush is a legendary Sativa strain with a name that has recognition even outside of the cannabis world. One thing that’s not up for debate is OG Kush’s potency — its THC composition has been consistently measured at between 20% and 25%. Medium to large nugget-like buds that have a dense, indica-like structure. The leaves are yellowish green. The high from OG Kush is more head-focused than physical. It starts with a sudden headrush that may lead users to feel more focused on their surroundings; sounds and colors may seem intensified. This alteration of the senses may soon give way to a general uplift in mood that progresses towards euphoria.
