A coke white tiger woke us from our slumber
To guide and protect us til the end
A white tiger is symbolized in Chinese Buddhism/mythology as one of the four spirit animals which serve as guardians for the directions of the compass. The white tiger is the protector of the West, where Frank is from. They also represent unpredictability and courage.
In this context he is characterizing cocaine as the white tiger, which protects them by the way one uses drugs as a way to escape reality, fitting in with a theme in the song, as, through cocaine, they are awakened spiritually.
