SB pretreatment significantly increased cocaine demand elasticity only when response-contingent, cocaine-associated light+tone cues were present. (A) In the group re-stabilized and retested with light+tone cues, SB pretreatment significantly increased demand elasticity (α) (*P = 0.05). (B) In contrast, SB pretreatment did not increase demand elasticity in the group re-stabilized and retested without light+tone cues. (C and D) Free cocaine consumption (Q0) did not change as a function of SB treatment when cues were present (C) nor when cues were absent (D).
