Kush is a strain of Cannabis indica. The origins of Kush Cannabis are from landrace plants mainly in Afghanistan, Northern Pakistan and North-Western India[1] with the name coming from the Hindu Kush mountain range. "Hindu Kush" strains of Cannabis were taken to the United States in the mid-to-late 1970s and continue to be available there to the present day.[2]

Kush strains were among those cultivated by the British firm GW Pharmaceuticals for its legally licensed commercial trial of medicinal cannabis.[3]
