Kush refers to a particular variety of cannabis that generally means a pure or hybrid Indica cannabis strain. Pure Indica Kush strains descend from the Hindu Kush mountains, a mountain range that spans the border of Afghanistan and Pakistan where the cannabis plant grows natively. When people refer to Kush, it generally means marijuana with the appearance of deep green colas and hints of purple, with dense, chunky buds. The effects of Kush are generally sedative and euphoric, for a happy meditative effect.
