Dark Star, also known as “Darkstar,” is an indica marijuana strain. Dark Star’s effects are as spacey as its name suggests: a deep, relaxed sensation throughout the body accompanied by a heavy cerebral calm. Though celestial in its effects, the strain is more likely homage to the Grateful Dead’s song “Dark Star.” A cross between Purple Kush and Mazar-I-Sharif, this dark, almost bluish strain was first bred indoors by T.H. Seeds.
