Focus Fox
Focus fox is an alertness drug. At the request of Demon Squad, Pantera Holland made a batch of extra-strong focus fox (super-focus-fox) for Jerry McCaskill prior to the exorcism of Cornelius Whitemarsh. She also created a powder which can be blown in one's face to undo the effects.
Before the adventure to the Fight Club, Elmer Dink took some of the super-focus-fox. He was hyper-alert for a week. As a remedy, Psspsspss gave Elmer four fingers of Fantasy Hennessy with two drops of cave drip in it. It induced stomach cramps and confusion, and was not effective at dispelling the effects of the focus fox.
