Rockstar Kush, also commonly called “Rockstar OG” by medical patients, is an indica dominant hybrid (75% indica/25% sativa) strain created through a cross of the insanely potent Rockstar X Bubba Kush strains.

The high starts with a feeling of uplifted euphoria with a hazy introspection that immediately relieves any feelings of anxiety or racing thoughts.
