My kush come from the land
This is a possible reference to California. California was a mythical island in Spanish folklore. When the Spaniards came across what is now California they thought it was an island due to the San Francisco bay and connecting rivers (the bay was quite larger than it is now). They named the land after the fabled island. In early maps California was even pictured as an island before they realized it was part of the mainland.
Wiz Khalifa has mentioned many time how his weed comes from Cali which is the best.
