GR translation: full of the Earth

[Mike Jing]

V683.21-32, P696.35-697.7   Säure got a lotta gall picking on other
people’s language like this. One night, back when he was a second-story
man, he had the incredible luck to break into the affluent home of Minne
Khlaetsch, an astrologer of the Hamburg School, who was, congenitally it
seems, unable to pronounce, even perceive, umlauts over vowels. That night
she was just coming on to what would prove to be an overdose of Hieropon,
when Säure, who back in those days was a curly-haired and good-looking kid,
surprised her in her own bedroom with his hand around an ivory chess Läufer
with a sarcastic smile on its face, and filled with good raw Peruvian
cocaine still full of the Earth—“Don’t call for help,” advises Säure
flashing his phony acid bottle, “or that pretty face goes flowing off of
its bones like vanilla pudding.”

What does "full of the Earth" mean here?
