In this episode of Miami Vice called “Payback” which aired on March 14, 1986, Frank Zappa plays Mario Fuente, the head of a drug ring dealing “weasel dust.”

I spent 13 years snorting weasel dust and the best part of the experience was the anticipation prior to snorting the first line. It was straight downhill after that.
