SB pretreatment increased cocaine demand elasticity without altering free cocaine consumption. (A) Normalized demand elasticity (α) was significantly higher in animals when they were pretreated with SB compared to when they were pretreated with vehicle (veh) (*P < 0.05). (B) Free cocaine consumption (Q0) was not altered by SB pretreatment compared to vehicle pretreatment. (C) Demand curves constructed from mean α and Q0 values to demonstrate the increased sensitivity of demand to price with SB treatment. (D) Baseline demand elasticity (abscissa) was not associated with change in demand elasticity from baseline with SB pretreatment (ordinate).
