Khalifa Kush, or Wiz Khalifa OG,  is a hybrid that was bred specifically for the rap artist Wiz Khalifa, who claims it descended from an OG strain. The ‘real’ Khalifa Kush is supposedly unavailable to the public, but those who have acquired strains under this name say that the effects and aromas are similar to that of OG Kush: sour lemon and pine, with an active cerebral buzz ideal for morning and daytime use. leafly.com
