Ace
From Halopedia, the Halo wiki
"Ace" is a slang term for a potent anti-anxiety agent. It is used predominantly on the human Outer Colony of Sedra, though the term has widespread usage throughout human-occupied space and can refer to a number of different drugs.[1] "Ace" is commonly combined with polypseudomorphine for recreational usage.[2]
