75% Indica / 25% Sativa Among its many features that OG Kush is famous for, its effects are the most important one. As one of the most potent strains in the market, OG Kush offers a powerful, quick setting, cerebral, and body-based high. The effects set in just minutes after smoking, and begin with strong feelings of euphoria, which are accompanied by an equally powerful body wide relaxing buzz. Not long after this, users can expect to find themselves seriously couch-locked and in a state of pure bliss. This is why many people consider OG Kush to be one of the best strains to help induce sleep and fight insomnia.
