We will develop a procedure for conditioning cue-cocaine associations in human drug users.
Next, we will reactivate that learning and intervene pharmacologically to prevent the
reconsolidation of cue-drug memories. We hypothesize that a combined behavioral and
pharmacological approach will have significant potential for persistently inhibiting relapse.
